Integrated Poultry Farming

Integration refers to the coordination and amalgamation of various stages in poultry production to create a seamless flow of inputs and outputs, reducing overall production costs. This approach ensures that each stage of production, from breeding to marketing, is efficiently managed within a unified system.

• Global Integration: In developed countries, poultry production is highly integrated, encompassing all stages from principal breeding to consumer distribution. This includes broiler farms, hatcheries, feed mills, processing plants, and animal healthcare products, which work together to streamline production and marketing processes.

• Indian Context: In India, integration and contract farming in poultry began with Suguna Poultry Farm Limited in 1991. While this marked the start of integration in broiler production, it did not fully represent the comprehensive integration seen in more developed systems.

• Current Practice in India: Integrators provide essential inputs such as chicks, feed, medicines, vaccines, and technical support. They also handle marketing of the final product. Poultry farmers, operating as contract growers, receive payments based on the weight of broilers or number of eggs produced. Despite these developments, integration within the layer sector remains underdeveloped in India.

Mixed and Integrated Poultry Farming

Mixed farming refers to the practice of cultivating crops and rearing livestock on the same farm, aimed at maximizing economic benefits through the efficient use of resources. This type of farming can be practiced either simultaneously or at different times, depending on the needs and conditions. In India, mixed farming is particularly significant as it typically contributes at least 10% of a farmer’s income from livestock, potentially reaching up to 49%.

Advantages of Mixed Farming

• Maximized Returns: By-products of farm activities, such as crop residues, can be effectively utilized to feed livestock, leading to higher returns.

• Year-Round Employment: Mixed farming provides continuous work opportunities throughout the year, ensuring a steady income.

• Efficient Resource Utilization: The combination of crops and livestock ensures optimal use of land, labor, and capital.

• Soil Fertility: Livestock manure contributes to maintaining and enhancing soil fertility, which is crucial for sustained crop production.

• Balanced Food Production: Mixed farming allows for the production of a variety of food items, leading to a more balanced diet throughout the year.

Organic Poultry Farming

Definition and Overview

• The FAO/WHO Codex Alimentarius Commission defines organic farming as a “holistic production management system that promotes and enhances agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity, using non-farm agronomic, biological, and mechanical methods, excluding all synthetic off-farm inputs.”

• Organic chicken farming involves raising chickens in a natural, humane environment outside of a conventional chicken house, feeding them organic feed (free from synthetic fertilizers, pesticides, and GMOs), and avoiding the use of antibiotics or growth hormones.

• The main goal is to produce healthier, environmentally friendly chicken products while ensuring high animal welfare standards.

• Conversion Period: Transitioning a conventional poultry farm to an organic one requires a certain period called the “conversion period.”

• Organic poultry farming necessitates the use of indigenous chicken varieties managed organically, allowing the birds to express their natural behavior.

• Growing Popularity: The demand for organic poultry meat is increasing due to heightened health awareness among consumers. Chicken, in particular, has become a key organic meat due to its shorter production cycle.

Introduction

Poultry diseases pose a significant threat to commercial poultry production, often resulting in substantial economic losses due to high mortality and morbidity. Early diagnosis and effective management of these diseases are crucial, as many diseases share similar symptoms, making timely and accurate identification challenging. Poultry diseases can be broadly classified into bacterial, viral, fungal, protozoan, parasitic, and nutritional deficiency diseases. The following table provides an overview of these diseases, their causative agents, symptoms, and prevention and control measures.

Poultry is one of the fastest-growing industries within agriculture and allied sectors worldwide. This rapid expansion results in the generation of substantial amounts of waste, including poultry manure, dead birds, hatchery wastes, and abattoir wastes. Proper treatment and scientific disposal of these wastes are crucial to avoid significant threats to both avian health and human safety. Unmanaged poultry wastes can lead to the spread of diseases among birds, resulting in considerable economic losses due to mortality and decreased productivity. Additionally, improper waste disposal can contribute to soil and groundwater pollution. Globally, an estimated 400 million chickens are processed weekly, generating a vast amount of waste. For instance, a broiler produces about 0.09 kg of manure daily, while a laying hen produces around 0.18 kg. Effective management of poultry waste requires a comprehensive understanding of its composition and the various physical, chemical, and microbiological processes that influence the fate of potential pollutants, particularly when the waste is applied to land.

Incubation is a critical process in poultry farming, involving the hatching of fertile eggs to produce chicks. This process can be carried out by natural or artificial means. Natural incubation involves placing eggs under a broody hen or duck, allowing the mother bird to provide the necessary warmth and conditions for hatching. In contrast, artificial incubation uses machines called incubators to create the ideal environment for the eggs to hatch. The incubation period, which varies among different poultry species, remains consistent within the same species regardless of whether natural or artificial methods are used.

Incubation

• It is simply the production of chicks by hatching fertile eggs either by natural or artificial means.

Reproductive Organs of Fowl and Formation of Egg

The reproductive system of a hen is a fascinating and intricate setup designed to produce one of nature’s most perfect foods-the egg. Understanding this system requires a look into its two primary components: the ovary and the oviduct.

The Ovary

The ovary is where the magic begins. A hen typically has two ovaries, but in most cases, only the left ovary develops fully and remains functional. The right ovary, although present, becomes rudimentary and non-functional. The left ovary is responsible for the formation of ova, the initial stage of the egg.

Inside the ovary of a hen are approximately 2000 visible yolk-filled ova. These ova are the potential eggs, each waiting to be developed and released. As a hen matures, these ova progress through various stages of development. The transformation from an immature pullet, which has a small, undeveloped oviduct weighing about 1.1 grams, to a mature pullet ready to lay eggs, involves significant changes. By the time a pullet lays her first egg, her oviduct has grown to weigh around 77.2 grams.

Feeds and Feeding of Poultry

Proper feeding is crucial for the optimal growth, health, and productivity of poultry. It constitutes a significant portion of the total production cost in poultry farming, often accounting for 70-75%. Understanding the different types of feed ingredients and their nutritional contributions is essential for formulating balanced diets that meet the specific needs of poultry at various stages of growth and production.

Different Feed Ingredients Used in Poultry

Poultry feed ingredients are broadly classified into four categories: energy rich feedstuffs, protein-rich feedstuffs, vitamin and mineral sources, and non nutritive feed additives. Typically, commercial poultry feeds are formulated by blending 10-15 different ingredients to provide a balanced diet that meets the nutritional requirements of the birds.

Introduction

The performance of any commercial stock (offspring) depends on the careful selection and scientific breeding of their parent stocks, known as “breeders.” Breeders are the backbone of any commercial poultry operation, as they produce the next generation of chickens, ensuring the continuity and quality of the flock. A breeder farm’s primary purpose is to produce a high number of fertile eggs per layer bird and to increase hatchability through proper hygienic handling of these eggs. Effective breeder farm management encompasses several key areas, including:

• Pure Line Management: Focusing on maintaining and improving specific genetic lines.

• Parent Stock Management: Managing the birds that directly produce commercial layers or broilers.

• Grandparent Stock Management: Managing the generation that produces parent stock, critical for maintaining genetic diversity and quality.

Care and Management of Meat-Type Chickens (Broilers)

Broiler Overview

• Broilers are unisex young chickens raised specifically for meat production. They are typically grown to reach a body weight of 2.0 to 2.5 kg within 5 to 6 weeks, consuming 3.0 to 3.5 kg of feed, resulting in a feed conversion ratio of 1.50 to 1.75.

• Broiler meat is flvored for its tenderness, high-quality protein content, low fat and cholesterol levels, superior flavor, and juiciness.

• The broiler production cycle is divided into three phases based on the birds’ physiological and production needs: broiler starter (0-10 days), broiler grower (11-21 days), and broiler finisher (22 days to marketing).

Brooding is a crucial phase in poultry management that involves the care of day old chicks during the early stages of their lives. Due to their underdeveloped thermoregulatory systems, chicks cannot maintain their body temperature and thus require external warmth. Proper brooding ensures the healthy growth and development of the chicks. The brooder unit typically includes several key components and considerations.

Brooding of chicks

1. Floor brooding

• Floor brooders (canopy/hover brooder or infra-red bulb brooder) are used to keep specific area(s) within the shed at the desired temperature.

• In canopy or hover brooding method, an umbrella-like canopy with two or three incandescent bulbs (40 to 100 W) each, depending on the season) are fixed at the centre, is inverted and hung in such a way that the birds can move freely in and out of it.

• The bulbs, when put on, heat the air and the hot air is trapped by the canopy preventing the escape of hot air thereby providing warmth to the chicks.

• The height of the brooder should be around 6 inches during the first week.

Housing of Poultry

Proper housing is essential for successful poultry farming, as it directly impacts the health, welfare, and productivity of the birds. Well-designed poultry housing not only provides protection and comfort but also ensures efficient management and optimal environmental conditions for the flock. This chapter explores the key aspects of poultry housing, including its purpose, site selection, and layout considerations.

Purpose of Poultry Housing

• Protection and Comfort: Provides a safe environment that shields birds from predators, harsh weather, and other external threats.

• Health and Welfare: Ensures optimal health and well-being by preventing diseases and reducing stress.

• Management: Facilitates easy and efficient management of the flock in a controlled and scientific manner.

• Cost Efficiency: Reduces overall production costs through efficient resource management.

Poultry rearing systems vary in scale and complexity, each suited to different production needs and environments. This chapter explores the main poultry housing systems, detailing their advantages and disadvantages to help in selecting the most appropriate method for various farming scenarios.

Housing Systems of Poultry

Generally, there are four types of housing systems in poultry, they are

1. Free range or extensive system,

2. Semi-intensive system,

3. Folding unit system and

4. Intensive system.

Desi chickens reared under backyard systems face several constraints such as lower productivity, higher incidence of disease outbreaks, high mortality rates during the early stages of life, and predation. Despite these challenges, the demand for rural backyard poultry is high, particularly among tribal households in rural areas. Small rural producers typically rear colored birds and produce brown-shelled eggs from Desi backyard poultry, catering to the requirements of rural consumers.

To address these issues, there is a need for specific rural poultry production programs. The Indian Council of Agricultural Research (ICAR), New Delhi, initiated a project to upgrade indigenous low input technology birds through the All India Coordinated Research Project on Poultry (AICRPP) in various parts of the country. This initiative aims to evolve improved rural backyard poultry breeds.

India’s indigenous poultry breeds play a crucial role in rural livelihoods, providing a sustainable source of nutrition and income. These native breeds are well-adapted to the local environmental conditions, demonstrating remarkable resilience and disease resistance. Despite their lower production potential compared to commercial breeds, their economic value and cultural significance make them indispensable in the rural context.

Indigenous Fowls of India

• India has a population of 217.80 million indigenous (Desi) chickens, representing 25.57% of the total poultry population (851.81 million) in India (BAHS, 2023, GOI).

• A total of 20 indigenous chicken breeds, 3 duck breeds, and 1 geese breed have been registered under the ICAR-National Bureau of Animal Genetics Resources (NBAGR) to date (Table 4.1 & 4.2).

• Indigenous fowls are typically reared under a backyard system, often referred to as “backyard poultry,” with minimal focus on housing and feeding.

Poultry Breeding

Poultry breeding is a scientific practice aimed at enhancing the genetic traits of birds to improve their productivity and quality. Historically, poultry farming began as small-scale backyard operations, but it has now evolved into a major industry. This transformation has been driven by the development of superi or breeds for both egg and meat production through advanced breeding and selection techniques. Modern poultry breeds exhibit significantly improved productive capacities, such as higher egg production and better meat quality, compared to their ancestors. Successful poultry breeding requires a deep un derstanding of the qualities and capabilities of various breeds, allowing breed ers to select and combine desirable traits to achieve specific goals, whether for size, weight, egg production, meat quality, or a combination of these factors.

• Poultry production has transitioned from a small-scale backyard venture to a significant industry.

• This growth has been largely driven by the development of superior breeds for egg and meat production, utilizing modern breeding and selection techniques.

Genetic Classification of Poultry

Understanding the genetic classification of poultry is essential for breeders and farmers to optimize the performance and standards of different commercial breeds. Here’s a detailed overview:

Evolutionary Background

• In the process of evolution, cold-blooded (poikilothermic) reptiles are considered the ancestors of birds.

• Birds are warm-blooded (homeothermic) feathered creatures adapted for hot and dry climates in their terrestrial habitats.

Chromosomal Categories

• Sex Chromosomes: Carry genetic material that determines the sex of an offspring.

• Autosomes: Non-sex chromosomes that carry the bulk of genetic information.

History of poultry production

Domestication of birds has a long history, with evidence of their existence and use dating back thousands of years. Here are some key points:

• Chickens: Archaeological evidence suggests domesticated chickens existed in China 8,000 years ago and later spread to Western Europe, possibly via Russia. The cockfighting in India 3,000 years ago indicates their cultural significance. Modern domestic chickens (Gallus domesticus) evolved from the wild red jungle fowl (Gallus gallus), native to India and Southeast Asia.

• Pigeons: The domestic pigeon (Columba livia f. domestica) is considered the world’s oldest domesticated bird.

• Geese: Domestic geese (Anseranserdomesticus in Africa, Europe, and West Asia; Ansercygnoides in East Asia) were domesticated in Egypt over 4,000 years ago and have significance in Roman mythology.

India ranks first in goat population with 148.88 million goats and 10.14% growth rate (DADF, 2019). Goat meat contributes around 37% of the total meat produced from the livestock sector in India which comes from the 42% of goat population annually (GOI, 2019). Goat has served as source of livelihood support and financial security to large section of society, especially to the resource-poor farmers. However, in the current scenario, this small ruminant farm animal has tremendous potential to be projected as the “Future Animal” for rural and urban prosperity. Rapid transformation of backyard goat farming to “commercial goat industry” is taking place in the country. The perception of goat as “poor man’s cow” to “preferred livestock species” is fast changing; therefore, to meet this transformation goat rearing system is shifting gradually from extensive low input system for livelihood purposes to semi- intensive and intensive rearing system for commercial purposes in India (Ramachandran et al., 2019). Due to their higher resilience capacity to climate change and better adaptability goats play significant role in ensuring food security. Goats have traditionally been a significant asset and source of protein for rural communities inhabiting arid and semiarid regions of the world. It is an endeavour of millions of small holders who rear animals on crop residues and Common Property Resources. The small holders produce milk, meat, fibre, skin etc for the community with virtually less capital investment, resources and formal training. They are conventionally raised on grazing resources. However, these resources are gradually shrinking over the periods both in terms of quality and quantity. On the other hand, there is continuous rise in the demand of meat which led to further deterioration of available grazing resources.

In India, agriculture is the primary occupation and source of income for the vast majority of the population. More than 58% of the population depends on agriculture for their living. Indian agriculture has been expanding for a long time with the help of related industries like sheep, goat, cow, chicken, and egg production. The world’s largest livestock population resides in India. For rural residents, the livestock industry is one of the most significant sources of revenue and employment. Agriculture and livestock are highly interdependent, with agriculture providing crop waste, a primary source of feed for livestock, while livestock provide manure and draught power to agriculture. The fact is that agricultural production and livestock raising work together to fully utilise a farm. In terms of giving families in rural and urban regions nourishing food, livestock is also crucial.

Because it is so straightforward, raising sheep and goats is more popular among landless, small, and marginal farmers who rely on common grazing and forest lands for food. Some of the factors responsible for the concentration of sheep and goat rearing among these categories include low capital intensity, prolific breeding, superior chevon/mutton quality, early sexual maturity, high-quality skin, low kidding intervals, good adaptability, no religious taboo against consumption, and steady returns.
