On-farm feed formulation involves preparing nutritionally balanced rations for livestock using locally available ingredients, while keeping in mind the animals’ dietary needs and the cost-effectiveness of components. This can be done either manually or through mathematical methods such as linear programming. Key elements of the process include understanding animal nutrient requirements, the nutritional profile of ingredients, and using tools like Pearson’s square for precise formulation.
This practice is a core aspect of natural feed management, enabling farmers to create customized feed mixes with natural, locally sourced inputs. It significantly reduces reliance on commercial feeds, lowers production costs, and promotes principles of ecological balance and self-reliance integral to natural farming systems. The aim is to meet the dietary needs of various livestock species—such as cattle, buffaloes, goats, poultry, and fish—during different life stages like growth, lactation, reproduction, and maintenance, using only natural, chemical-free components.
Frequently used natural ingredients include the folloning:
• Cereal Grains: Maize, sorghum, pearl millet, rice bran (as energy providers)
• Oilseed Cakes: Groundnut, mustard, sesame (for protein)
• Pulse Residues: Broken pulses and husks (rich in digestible protein)
• Green Forages: Moringa, lucerne, subabul, cowpea (sources of vitamins and minerals)
• Minerals: Rock salt, lime powder, ash, crushed bones or eggshells
• Natural Additives: Neem leaves, garlic, turmeric, and fenugreek (for health and digestion)
Common techniques in feed Formulation are as bollows:
• Mixing ingredients manually in proportions suited to the animal’s requirements
• Enhancing digestion and microbial activity using Jeevamrit or other fermented inputs

In natural farming-based aquaculture, feed management emphasizes sustainable practices that utilize naturally occurring food sources along with lowcost supplements. This method reduces dependency on commercial feeds and chemical inputs, aligning with eco-friendly farming principles and supporting aquatic biodiversity. Fish raised in natural farming systems primarily feed on natural organisms such as plankton, algae, and detritus. These develop in ponds fertilized with organic inputs like cow dung and compost, which help create a self-sustaining aquatic ecosystem. Fish thrive by feeding through the natural food chain, minimizing the need for external inputs.
Supplementary feeding includes locally sourced plant materials such as azolla, duckweed, water hyacinth, and aquatic weeds that are rich in nutrients. Farmers also use kitchen waste, crop residues, and agricultural byproducts like rice bran and wheat bran to enhance nutritional value.
Fermented feed mixtures—made using bran, cow urine, and microbial solutions—are applied to improve digestion and nutrient uptake. These probiotic feeds support fish health and improve immunity without resorting to synthetic additives. Regular pond maintenance, including partial water renewal and organic fertilization, supports the continuous generation of natural feed organisms. This ensures a balanced and productive environment for fish rearing.
Adopting such natural feed strategies leads to healthier fish, reduced environmental impact, and lower input costs. It also complements integrated farming systems, contributing to farm sustainability and diversified income opportunities.

Backyard poultry rearing plays a vital role in natural farming systems, offering rural households a steady source of eggs, meat, and supplementary income with minimal financial input. This practice emphasizes the use of natural, locally available feed resources, avoiding dependence on commercial feeds or synthetic additives such as antibiotics.
In such systems, the poultry diet largely comprises kitchen leftovers, farmsourced grains, green leafy plants, and insects. Birds are typically allowed to forage freely, enabling them to consume a diverse range of natural items like worms, seeds, and tender greens. This scavenging behavior supports their nutritional needs by naturally providing proteins, minerals, and essential vitamins necessary for optimal growth and egg production.
To enhance their diet, farmers often include cereals such as maize, sorghum, and millet, along with protein-rich additions like pulses and oilseed cakes. Green fodders—particularly nutrient-dense options like moringa and amaranth leaves— are commonly supplied to boost vitamin and mineral intake.
Natural immunity boosters such as turmeric, neem leaves, and garlic are frequently incorporated into the birds’ feed or drinking water. These traditional herbal additives help strengthen resistance to disease, support digestion, and reduce parasitic loads. In some cases, fermented mixtures prepared from ingredients like cow dung and jaggery—resembling Jeevamrit—are provided to support gut health through probiotic action.
Providing clean, fresh water remains fundamental to maintaining poultry health. Feeding regimens are adapted to seasonal conditions, ensuring that nutritional requirements are met during periods of increased egg production or breeding.

Goats and sheep play a vital role in natural farming systems due to their adaptability, efficient utilization of feed, and importance in sustaining rural livelihoods. Proper feed management is key to ensuring their health, reproductive success, and overall productivity, all while reducing reliance on external inputs. In natural farming, the diet of goats and sheep mainly consists of locally available grasses, shrubs, tree foliage, crop residues, and forage legumes. Fodder trees such as subabul, moringa, ber, and neem serve as valuable sources of protein and micronutrients. To address seasonal shortages, farmers establish fodder reserves and adopt agroforestry systems that combine tree planting with crop cultivation.
Goats, being browsers, thrive on a wide variety of vegetation including tough shrubs and woody plants, many of which contain medicinal secondary compounds. Sheep, on the other hand, prefer grazing on grasses and herbs, making careful pasture management essential to prevent nutrient deficiencies.
Locally sourced feed supplements like oilseed cakes, pulses, and leftover kitchen food help improve protein and energy intake. Mineral blocks enriched with salt, calcium, phosphorus, and trace minerals aid in proper skeletal development and reproductive health.

Cattle and buffalo are central to livestock-based livelihoods in India, particularly within natural farming systems where emphasis is placed on maintaining animal health and productivity without the use of synthetic inputs. The feeding strategy in such systems is built around the use of locally available, chemical-free resources that support sustainability and ecological harmony.
The core of the diet for cattle and buffalo in natural farming includes green fodder, dry crop residues, and naturally sourced supplements. Green fodders such as napier grass, guinea grass, berseem, and various legumes provide essential nutrients and roughage. These are complemented by dry fodders like wheat and paddy straw, which are vital for maintaining rumen health through their fiber content.
Natural concentrates such as oilseed cakes (from mustard, groundnut, etc.), along with pulses and mineral sources like crushed limestone and rock salt, are used to supply energy, protein, and essential minerals. In addition, herbs like turmeric, ginger, and ashwagandha are incorporated to enhance digestion and boost immunity naturally.
Seasonal fodder planning is practiced to maintain a continuous supply of feed throughout the year. Farmers often rely on traditional microbial additives such as Jeevamrit—a fermented solution made from cow dung, cow urine, jaggery, and water—which promotes gut health and improves feed efficiency.
Clean and sufficient water access is also a priority, with adult cattle and buffalo requiring around 30 to 50 liters per day depending on body size and milk production.

Natural farming systems aim to reduce dependence on expensive commercial feeds by integrating locally available, non-conventional feed
resources and crop residues. These materials are not only cost-effective and environmentally friendly but also help bridge fodder shortages during lean seasons while recycling agricultural waste.
Non-conventional feeds encompass a wide array of agricultural byproducts, including oilseed cakes from neem, mahua, and karanja; legume
haulms; discarded fruits and vegetables; kitchen waste; and various agroindustrial residues. These resources are often rich in proteins, fibers, and minerals, and when used judiciously, can effectively supplement conventional fodder.
Crop residues such as wheat straw, paddy straw, maize stalks, sugarcane tops, and groundnut haulms are commonly used as dry roughage for ruminants in India. While these are generally low in protein, their fiber content is significant and can be enhanced through simple treatments like chopping, soaking, or fermenting with natural inputs such as Jeevamrit or urea to improve digestibility.
Integrating these alternative feed resources supports the principles of circular agriculture by reducing environmental waste, cutting down on feed expenses, and improving the sustainability of livestock systems. Nonetheless, appropriate care must be taken to avoid incorporating harmful or poorly digestible substances, and nutritional supplementation may be required to ensure optimal animal health.

In natural farming, feed supplements and probiotics made from organic and locally available materials are essential for improving animal health, digestion,and immunity. These methods provide a sustainable alternative to synthetic additives and antibiotics, aligning with eco friendly farming principles.
Natural feed additives consist of mineral-rich and herbal materials that enhance nutritional intake. Common sources include rock salt, powdered eggshells, bone meal, and herbal preparations made from plants like neem, turmeric, ginger, and ashwagandha. These supplements are valuable in addressing nutritional deficiencies in standard fodder, thereby supporting various physiological functions such as metabolism, reproduction, and disease resistance.
Probiotics, which are beneficial microorganisms, help establish and maintain a healthy gut environment in livestock. They facilitate better digestion, improve nutrient absorption, and prevent harmful bacteria from taking hold in the digestive system. Natural farming relies on probiotic-rich preparations such as Jeevamrit, Amritpani, and fermented cattle urine, all of which contain lactic acid bacteria, yeasts, and other helpful microbes.
Benefits of feeding probiotics are given below:
• Enhanced digestion of fibrous feed, improving energy use.
• Strengthened immune system, reducing dependence on antibiotics.
• Prevention of common digestive issues like diarrhea.
• Increased growth and milk production in livestock.
Homemade probiotic mixtures are commonly prepared by fermenting natural ingredients such as cow dung, jaggery, and fresh cow urine under anaerobic conditions. These cost-effective and eco-conscious preparations fit seamlessly within the framework of natural farming.

Fodder serves as the foundational element of livestock nutrition within natural farming frameworks. Providing animals with a consistent, nutritious, and chemical-free fodder supply throughout the year is essential to maintaining their health, optimizing productivity, and ensuring long-term sustainability. In contrast to commercial models that often depend on externally sourced feed concentrates, natural farming promotes the cultivation of fodder on-farm through organic and regenerative practices. India’s fodder supply is typically divided into the following categories:
• Green Fodder: This includes grasses like Napier, Guinea, and Dinanath, as well as legumes such as Berseem, Lucerne, and Cowpea, and nutrient-rich tree leaves from Moringa, Subabul, and Neem.
• Dry Fodder: Comprising crop residues like wheat straw, paddy straw, maize stalks, and groundnut haulms.
• Pasture and Forest Grazing: Utilization of common lands, silvopasture systems, and forest areas for grazing.
• Fodder Trees and Hedges: Protein-rich varieties like Gliricidia, Sesbania, and Leucaena, which also enhance soil fertility.
In natural farming, fodder crops are grown without the use of chemical fertilizers or pesticides. Farmers enrich soil and seeds with preparations like Jeevamrit and Beejamrit. Mulching helps conserve soil moisture, suppress weed growth, and foster microbial activity. Intercropping and crop rotation with cereals and legumes maintain ecological balance and soil vitality. Zero Budget Natural Farming (ZBNF) methods integrate livestock with crop cycles to regenerate fodder naturally.
The establishment of fodder banks and use of staggered sowing patterns ensures a steady supply even during off-seasons. In arid regions, drought-tolerant and native fodder varieties are prioritized to uphold fodder security.

India boasts a long-standing heritage of indigenous and ethnoveterinary knowledge in livestock care, developed over generations through careful observation, experience, and adaptation to local conditions. These practices emphasize sustainability and affordability, making them particularly valuable for small-scale and marginal farmers. By relying on readily available, seasonal, and natural resources, they align closely with ecological principles and traditional wisdom.
Feeding methods rooted in indigenous systems often utilize locally sourced tree leaves, grasses, agricultural residues, and customized herbal or homemade concentrates. Fodder options such as neem, babul, ber, subabul, moringa, and arhar leaves are commonly used, appreciated both for their nutritional content and medicinal properties. In several rural communities, animal diets are enhanced with supplements like bran, oilseed cakes, fermented grains, and by-products such as buttermilk residue, all aimed at improving digestion, health, and milk production.
Ethnoveterinary approaches focus on disease prevention and treatment through natural substances. Ingredients like turmeric, garlic, fenugreek, ashwagandha, and shatavari are frequently added to fodder or water to promote immunity, reproductive efficiency, and general vitality. A common post-calving practice involves feeding a mix of jaggery, wheat bran, and ajwain to lactating cows to aid in uterine cleansing and boost milk secretion.
These traditional methods offer a viable alternative to commercial feeds, synthetic additives, and antibiotics. Deeply rooted in regional customs and passed down through generations, they represent a rich repository of community knowledge. Documenting and validating these practices through scientific inquiry and participatory research can reinforce the resilience of rural livestock systems.

Animal nutrition involves providing balanced diets to farm animals to maintain their health, support growth, facilitate reproduction, and ensure high productivity. In the context of natural farming, this discipline emphasizes the useof local, naturally available feed resources, steering clear  of synthetic or commercial formulations. A sound understanding of basic nutrition and digestive physiology is crucial for creating sustainable and effective feeding strategies.
Farm animals need six fundamental nutrient groups: water, carbohydrates, proteins, fats, vitamins, and minerals. Each plays a vital role—whether in producing energy, repairing tissues, maintaining immunity, or supporting reproductive and lactation processes. Nutritional needs are influenced by species, age, physiological status (such as growth, pregnancy, or milk production), and the animal’s activity level.
Animals vary in digestive anatomy, which affects how they process feed. Ruminants—including cattle, buffalo, sheep, and goats—have a four-part stomach (rumen, reticulum, omasum, and abomasum) that enables them to digest fibrous plant matter efficiently through microbial fermentation. In the rumen, microbes break down cellulose and produce volatile fatty acids (VFAs), which serve as a primary energy source.
On the other hand, monogastric animals like pigs and poultry have a single-chambered stomach. They depend more heavily on readily digestible carbohydrates and proteins, making grains and high-protein plants ideal for their diets. Recognizing these physiological distinctions allows farmers to select feed resources appropriately—roughages and crop residues for ruminants, and concentrated energy and protein sources for monogastrics.
In natural farming systems, nutrition is supplied through a diverse mix of green fodder, leguminous leaves, tree foliage, crop by-products, and fermented inputs like Jeevamrit. These methods maintain animal health and productivity without resorting to synthetic additives, antibiotics, or hormones.

Natural Farming (NF) represents a sustainable approach to agriculture that draws upon ecological principles, minimizes reliance on external inputs, and makes extensive use of locally available resources. In contrast to conventional farming—which often depends on synthetic fertilizers and commercial animal feed—natural farming seeks to foster balance among the soil, crops, animals, and microbial life. Popularized in India by Subhash Palekar, this method promotes the use of natural preparations such as Jeevamrit, Beejamrit, and practices like mulching to enrich soil fertility and support plant vitality.
A core aspect of natural farming is the inclusion of livestock, which significantly contributes to nutrient recycling, weed suppression, and overall farm efficiency. Products like cow dung and urine form the basis of microbial formulations that boost soil activity and crop productivity. Livestock also contribute to ecological health through regulated grazing, pest management, and the breakdown of organic residues.
Animals such as cows, buffaloes, goats, sheep, backyard poultry, and fish are effectively integrated into the NF system to form a cohesive and regenerative agro-ecosystem. These animals enhance crop systems by providing organic inputs while simultaneously benefiting from pesticide-free fodder and farm-generated feed, leading to healthier livestock and improved quality of dairy, eggs, and meat.
This interdependent model reduces the need for external feed inputs, enhances natural animal wellness, and raises farm income, particularly for smallholders. Natural farming promotes the use of native breeds that thrive in local conditions with minimal intervention.
Ultimately, integrating livestock within natural farming is not just beneficial— it is vital for establishing robust, regenerative farm systems. This synergy between animals and crops supports ecological sustainability, strengthens food systems, and uplifts rural communities.

Whole blood, plasma, serum, and blood transfusions are critical life-saving therapies in veterinary medicine. They are used to restore blood volume, correct anemia, provide clotting factors, and address protein deficiencies in various disease conditions. This chapter discusses their administration doses, species-specific considerations, and disease conditions where these fluids are essential.
Key components of blood therapy
1. Whole blood: Contains red blood cells (RBCs), plasma, clotting factors, and platelets.
2. Plasma: The liquid portion of blood with clotting factors, albumin, and immunoglobulins but without RBCs and platelets.
3. Serum: Plasma without clotting factors.
4. Packed red blood cells (pRBCs): Concentrated RBCs used to treat anemia without volume overload.

Fluids and electrolytes are critical in managing dehydration, electrolyte imbalances, and shock in animals. These life-saving interventions restore homeostasis in various disease conditions. Fluid therapy is tailored based on species, body weight, disease condition, and hydration status, ensuring proper restoration of blood volume, electrolyte balance, and acid-base homeostasis. Principles of fluid therapy
1. Types of fluids
Crystalloids: Normal saline, Ringer’s solution, and lactated Ringer’s solution (LRS). Colloids: Plasma, hydroxyethyl starches, and dextrans. Dextrose solutions: For energy supply and hypoglycemia.
2. Routes of administration:
Intravenous (IV): For severe dehydration and shock.

Milk impaction in neonatal calves is a condition characterized by the improper digestion or accumulation of milk in the abomasum, leading to digestive disturbances, discomfort, and potential health complications for the calf. This condition is most commonly seen in newborn or very young calves; typically within the first few days to weeks of life, as their digestive systems are still developing and may be more susceptible to dysfunctions. Causes of milk impaction
Several factors can contribute to milk impaction in neonatal calves. Understanding these causes is essential for prevention and treatment. The primary causes are:
1. Overfeeding or undigested milk: One of the most common causes of milk impaction is overfeeding, where the calf is fed more milk than it can digest properly. Overfeeding can overwhelm the capacity of the
abomasum, leading to a backup of undigested milk. Undigested milk in the stomach can ferment, creating an acidic environment that may disrupt normal digestion and lead to impaction.
2. Inappropriate milk temperature: Milk fed to calves should be at the proper temperature, usually between 38-39°C (100-102°F). Milk that is too cold can cause a delay in the digestive process and lead to impaction, as it may not be digested as quickly as milk at the ideal temperature. Similarly, milk that is too hot can cause digestive stress or irritation.

Vitamins and minerals play crucial roles in supporting immune function across various animal species. Their supplementation can enhance immune responses, reduce disease susceptibility, and improve overall health. The appropriate doses vary depending on species, physiological state, and environmental conditions.
Cattle
1. Vitamins
Vitamin A: Enhances mucosal immunity; 30,000–50,000 IU/day.
Vitamin D: Supports macrophage function; 10,000–15,000 IU/day.
Vitamin E: Antioxidant, improves phagocyte function; 500–1,000 IU/
day.
2. Minerals
Zinc: Promotes wound healing and immune cell activity; 40–60 mg/kg feed.
Enhances neutrophil and antibody responses; 0.3 mg/kg feed.
Sheep and Goats
1. Vitamins
Vitamin A: 5,000–10,000 IU/day.
Vitamin E: 200–400 IU/day to enhance antioxidant defenses.
Vitamin D: 2,000–3,000 IU/day to maintain calcium balance and immunity.

Probiotics and prebiotics are widely used in animal nutrition to promote gut health, enhance immune function, and improve production performance. Probiotics are live microorganisms (e.g., Lactobacillus, Bifidobacterium, Bacillus, and Saccharomyces) that confer health benefits when administered in adequate amounts. Prebiotics, such as fructooligosaccharides (FOS) and mannanoligosaccharides (MOS), are non-digestible compounds that stimulate the growth of beneficial gut microbes. The optimal supplementation levels vary among speciesbased on their physiology, diet, and production goals.
Cattle
Probiotics
Lactobacillus acidophilus, Bifidobacterium bifidum, Enterococcus faecium,and Saccharomyces cerevisiae are commonly used.
Dose
Lactobacillus spp.: 1 × 109– 1 × 1010 CFU/head/day.
Saccharomyces cerevisiae: 5–10 g/head/day or 108– 109 CFU/g feed.
Prebiotics
MOS and FOS are used to improve gut integrity and nutrient absorption.

Omega-3 fatty acids, primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are renowned for their anti-inflammatory properties. They modulate inflammation by competing with arachidonic acid, reducing pro-inflammatory eicosanoids, and enhancing anti-inflammatory resolvins and protectins. The optimal supplementation dose varies among animal species due to differences in metabolism, physiology, and dietary requirements.
Dogs
For dogs, omega-3 fatty acids are often used to manage inflammatory conditions like arthritis and dermatitis. Doses of 50-100 mg/kg body weight of combined EPA and DHA are commonly recommended, with variations based on the severity of inflammation and the dog’s health status.
Cats
In cats, omega-3 supplementation is used for similar conditions as in dogs. Typical dose ranges from 30-50 mg/kg body weight of EPA and DHA, taking into account their strict carnivorous diet and specific fatty acid metabolism.
Horses
Horses benefit from omega-3 supplementation in conditions such as osteoarthritis and inflammatory airway disease. The recommended dose is about 4-6 g of combined EPA and DHA per day for an average-sized horse (~500 kg). Flaxseed oil, rich in alpha-linolenic acid (ALA), is also commonly used, although its conversion to EPA and DHA is limited.

Advances in technology are revolutionizing the detection of metabolic diseases in animals, making diagnostics more precise, rapid, and non-invasive. From wearable sensors and metabolomics to AI and nanotechnology, these tools are enhancing animal health and productivity. As these technologies become more accessible, they promise to transform veterinary medicine and animal husbandry, ensuring early detection, effective management, and improved outcomes for animals.
Sensor-based technologies have emerged as a game-changer in the detection and management of metabolic diseases in dairy animals. These tools provide continuous monitoring, early detection, and real-time insights, enabling better health management and increased productivity. This chapter explores the most promising sensor-based technologies used for diagnosing metabolic diseases in dairy animals, their applications, and the future of sensor-driven animal health management.
Metabolic diseases like ketosis, milk fever (hypocalcemia), acidosis, and displaced abomasum significantly impact dairy productivity and animal welfare. Early detection is critical for reducing treatment costs, improvingrecovery rates, and minimizing production losses. Traditional diagnostic methods are accurate and often invasive, time-consuming, and not feasible for large-scale monitoring. Therefore, sensor-based technologies offer a solution by enabling continuous and non-invasive monitoring of physiological and biochemical parameters.

The heart, composed primarily of specialized muscle tissue known as cardiac muscle, is responsible for maintaining the circulatory system’s function by pumping blood throughout the body. The unique characteristics of heart muscle allow it to respond dynamically to various physiological demands. Among these adaptive responses, hypertrophy, atrophy, and the process of pacemaking are fundamental to heart function and health. Understanding these processes is crucial for comprehending how the heart responds to different stressors, such as physical activity, disease, or aging, and how its electrical and mechanical functions are integrated.
Nature of cardiac muscle
Cardiac muscle is a specialized type of muscle tissue found only in the heart. It is unique because it combines features of both skeletal and smooth muscle, providing both strength and rhythm in its contractions. Cardiac muscle fibres are striated and connected by intercalated discs, which allow rapid transmission of electrical impulses between cells, ensuring synchronized contraction. Unlike skeletal muscle, cardiac muscle has a relatively high density of mitochondria, providing the energy necessary for continuous activity.

Haemostasis refers to the physiological process that prevents blood loss following vascular injury while maintaining fluid blood flow within the vascular system. It involves a complex interplay between the vascular endothelium, platelets, coagulation factors, and fibrinolytic proteins. In animals, laboratory tests for haemostasis play a critical role in diagnosing bleeding disorders, monitoring treatment, and investigating hypercoagulable states. This article discusses the principles, applications, and limitations of laboratory tests used to assess haemostasis in animals.
In veterinary medicine, laboratory tests for haemostasis are essential diagnostic tools for identifying bleeding disorders, hypercoagulable states, and monitoring therapeutic interventions. They are crucial in both emergency and routine clinical settings for animals. These tests provide insights into the functionality of primary haemostasis (platelet plug formation), secondary haemostasis (coagulation cascade and fibrin clot formation), and tertiary haemostasis (fibrinolysis and clot breakdown).
