Introduction

In developing countries, ruminants thrive mainly on poor quality feeds and pastures, whose nutritive value is poor. They are having a low content of nitrogen, energy, minerals and vitamins and high content of lignin and silica, which limit their efficient utilization by ruminants. Therefore, these poor quality feeds and fodder needs to be upgraded in terms of their nutritive value using various treatments like physical, chemical, physico chemical and biological methods to improve intake and utilization of nutrients from poor quality roughages. However, supplementation of critical nutrients like energy, protein, minerals, vitamins also improved the productivity and health of the ruminants (Dass et al., 2011). Availability of oil cakes as protein supplement in developing countries is very poor and at a very high price, This has led to use of non-protein nitrogen source as urea, to compensate for the nitrogen deficiency of fibrous feeds (Dutta et al., 2009). Thus, enhancing intake, digestibility and availability of nutrients from poor quality roughages are only possible through optimization of rumen fermentation. The use of solid multi-nutrient block supplementation /urea-molasses blocks/ multi nutrients blocks/ pashu chocolates to provide optimum levels of various nutrients primarily for better growth of rumen micro organisms. They need rich sources of fermentable nitrogen, minerals and vitamins, which are lacking in the fibrous feeds like cereal straws (Sahoo et al, 2009). This offer several advantages such as easy transport, storage and handling, and reduced risks of poisoning as compared with other approaches, such as giving a small amount of urea in drinking water, sprinkling of urea solution on fibrous feeds before feeding, or urea-ammonization of crop residues (Dutta et al ., 2009).

A single active ingredient often is sold in several different kinds of formulations as follows:

(a) Dry Formulations
1. Granule (G)

Granule is, a ready-to-use, dry mixture of a small amount of active ingredient with inert carriers. Most are made by applying a liquid formulation of the active ingredient to coarse particles (granules) of some porous material such as clay, sand or plant material. Granule particles are much larger than dust particles; will pass through a 4-mesh sieve but not through an 80-mesh sieve (the number of wires per inch). The herbicide is absorbed into the granule, or coats the outside of it, or both. Inert ingredients may be added to make the formulation handle well. The amount of active ingredient usually ranges from 1 to 15 percent.

A premixisa mixtureofvitamins, trace minerals, medicaments, feedsupplements and diluents either individually or in a combination. It is a value added solution for feeds with sustainable safety and quality.

The main objective of premixes is to deliver the micro-ingredients in a manner desired by customer. These blends of Micro-ingredients need to be carefully selected, analysed and homogenously manufactured in controlled conditions.

Good quality premixes are manufactured as per following four fundamental principles that determine premix quality and performance :

1. Understanding the chemical and physical attributes in the microingredient to be incorporated.

2. Testing to ensure that all microingredients meet specifications.

3. Controllingthe inclusionin fullproof and secure method.

4. Blending together in speciality mixers to achieve a homogenous mix.

The formulation of ration for various categories of livestock depends upon the nutrient requirements for a particular animal or group of animals and the feeds and fodders available for the purpose. Livestock feeds can be grouped into two major categories – Roughages and concentrates, on the basis of bulkiness and chemical composition and combination of both is essential for a balanced ration.

Roughages are the bulky feeds having crude fiber more than 18% and TDN less than 60% while, Concentrates are feed or feed mixture having crude fiber less than 18% and TDN more than 60%. They are rich in either energy or protein and accordingly are called as energy concentrates (when CP is less than 18%) or protein concentrates (when CP value exceeds 18%). Various energy concentrates are grains and seeds (maize, barley, sorghum etc.), milling byproducts (brans and chunis), roots (tapioca tubers, turnip, potatoes) and molasses.

When two or more chemicals can be used in combination or mixed safely, they are said to be compatible. These combinations can be a pesticide mixed with another non-pesticide chemical, or can be two or more pesticides that are combined in the same tank mix. The reasons for combining pesticides are:

1.To control different types of pests with a single application. Often, several types of pests need to be controlled at the same time. It is generally more economical to combine the pesticides needed and make a single application.

2.To provide superior control than that obtained from one pesticide. Applicators at times combine active pesticides to kill a pest that has not been effectively controlled by either chemical alone. Many combinations are quite effective, but in most cases it is not known if the improved control is a result of an additive effect or a synergistic action of the combined chemicals on different segments of the pest population. One should always check the label prior to verify the safety and legality of mixing pesticides.

3.To increase the effectiveness of one of the chemicals. As mentioned above, this is called synergism. The material added to increase the effectiveness of the primary chemical is called a synergist. The synergist may not necessarily be pesticidal by itself, but increases the effectiveness of the pesticide with which it is combined.

The word biscuit is derived from Danis biscoctus which is Latin for twice cooked bread and refers to bread rusks that were made for mariners (ships biscuits) since the Middle Ages. The dough pieces were baked and then dried out in another cooler oven. All biscuits are made with flour (usually wheat flour) and all have low moisture content and thereby have long shelf life if protected from moisture and oxygen. It includes items also known as crackers (that make a noise of cracking when broken), Hard sweet and semi –sweet biscuits, cookies (which is the name that originated from Dutch word koekje meaning a small cake) and wafers, which are baked between hot plates from a fluid batter. The name cookie was adopted in North America where the term ‘biscuit’ can be confused with small soda raised breads or muffins. In other countries the term cookie is used primarily for wire cut products of rather rough shape, which often contain large pieces of various ingredients such as nuts, etc. The term ‘biscuit’ is used in Britain to describe a flat, crisp, baked product; the term cookie is reserved for something softer and thicker. Cookies are made from soft wheat flour and are characterized by formula high in sugar and shortening and relatively low in water. Similar product is known as biscuit in our country. In USA the term ‘cookie’ covers any flat, crisp, baked good. Cracker is a term reserved for biscuit of low sugar and fat content, frequent bland or savoury. Crackers are usually made from developed dough whereas cookies are made from weaker flour. These foods have in common their ability to stay palatable for a long period of time. Their ease of transportation and their ready consumption without any further preparation make them high on the list of staple snacks

All bread is made by baking a dough that has two basic ingredients, flour or meal and a liquid. Bakers can use a wide variety of both components. The most common type of flour used for bread and most other baked goods is made from wheat. Wheat flour has a pleasant taste and contains a large amount of an elastic protein substance called gluten. Gluten aids in baking uniformly light bread that rises (swells) properly. Other baking flours are made from barley, rye, corn, rice, oats, soybeans, and potatoes. These flours, particularly soybean flour, may equal wheat nutritionally, but none can match wheat for creating light, even-textured bread. Hard wheat flour makes lighter bread than does soft wheat flour because it is richer in gluten. Rye and whole wheat breads are made lighter by adding white flour. The liquids used in baking include water, sweet or sour milk, yogurt, wine, and beer.

Bread is either leavened or unleavened. Leavened breads contain some substance that produces bubbles of carbon-dioxide gas. These gas bubbles inflate the dough, causing it to rise and become light and porous. Most kinds of basic breads are leavened with a fungus called yeast. Biscuits, muffins, and cakes and other pastries are leavened with either baking powder or baking soda. Unleavened bread is dry and hard. Familiar kinds of unleavened breads include water crackers, the rye crisp of Sweden, and Jewish matzoth. Whether leavened or unleavened, most breads contain other ingredients in addition to flour and a liquid. An almost limitless variety of breads can be made by adding a sweetener, shortening, cheese, eggs, meat, fruit, vegetables, seeds, or nuts. A sweetener, either sugar or syrup, is used in almost all bread for its taste or as an aid to yeast growth. Bread may also have an external sweetener in the form of a decorative glaze. The high fat content of shortening and cheese increase tenderness and flakiness in bread. Perhaps the best example is the French croissant. Eggs help leaven bread dough by adding to the bread’s lightness. They can be brushed on top of the dough before baking to create a shiny crust, as in the Jewish hallah. Some breads from many nations contain fruit, a vegetable, meat, seeds, or nuts. Examples include the fruit scone of Great Britain, the spinach paratha of India, the Southern sausage bread of the United States, the Easter sesame bread of Greece, and the almond sweet bread of Finland.

Cakes are sweet baked products characterized by high level of sugar in the formulation and hence are foods of high calorific value. Among the various ingredient used flour, sugar, shortening and egg are the essential ingredients for cake manufacture. The optional ingredients are baking powder, milk, fruit etc. For cake manufacture the selection of ingredients is of paramount importance.

Major advantage of chemical herbicides over other methods of weed control is its ease of application, which saves the cost of labour for the farmer. Effectiveness of herbicide depends on how long it remains in active form in the plant /soil. The form in which any herbicide is available in the market is known as herbicide formulation. The technical active ingredient (ai.) of the herbicide is converted to a formulations so as to improve easiness of handling, retention on leaf surface, absorption and movement in the plant. Herbicides are available in different formulations.

Biofertilizer is already proven to be beneficial for agricultural and horticultural crops. The most important pre-requisite for the success of biofertilizer application is the presence of high population of viable cells which will show the desired effect on plants. Biotic interactions along with competition from native microflora is a major challenge to an applied strains of biofertilizers. The formulation is an important parameter for biofertilizer production containing efficient microbial strain with suitable carrier material and additives. The microbial strain needs suitable protective environment to increase their efficiency at the target site and also make it user-friendly. Performance of biofertilizers under field condition is the major requirement for inoculants. Inadequate formulations and poor inoculant quality are the major hurdles for the successful use of biofertilizers.

Formulation of biofertilizers has to be consistant during production, distribution, storage and transport to the farmer/end users. The shelf-life of inoculated microbial fertilizer depends on the formulation with suitable carrier material. If local production and distribution of an efficient native biofertilizer formulations are developed, the present problems in the field performance of biofertilizers could be significantly solved. Specific formulations of native strains for use in saline soils, acid soils, drought, high temperature and eroded soils requires specific formulations. Therefore,use of native strains of biofertilizer formulations which are tolerant to the abiotic stress is an important approach. The formulations of biofertilizers are challenging and limited success has been observed in the commercialization of new biofertilizers. Hence, the search for new formulations has been a continuous approach. However, the choice of the formulation depends on the application method, available equipment, farmer’s convenience, plant inherent characteristics and developmental stage, cost, mode of action and colonization pathway of the inoculated strain. Conventionally, solid based formulations are used, which have problems of low viability during storage and application.

Fungicide Formulation

Fungicide formulation is the process by which the fungicide is put into a form which can be easily produced, stored, transported and applied by practical methods in order to achieve a safe, convenient economic and effective method of disease control.The mixture of active ingredient and inert (inactive) ingredients is called a fungicide formulation.

INTRODUCTION

Many people confuse fortification with the term enrichment. There is a big difference in between these two terms. Fortification means the addition of those ingredients not normally found in a food and it is added to achieve a particular dietary purpose. Lysine may be added to corn products to increase the biological value of the protein. Salt may be iodised to prevent the occurrence of goiter. Breakfast cereals may be fortified with an array of vitamins and minerals to ensure a completely balanced nutritional meal.

In enrichment, the amounts added are designed to meet specific legal standards of minimum and maximum levels of nutrients. It is recognised that in the processing of cereal products that the removal of bran and germ causes a large portion of the vitamins and minerals naturally found in the product to be lost. During World War II an effort was made to correct this deficiency by government endorsement of the enrichment of bread, flour, and cornmeal. Wheat flour, cornmeal, corn grits, bread, ready to eat and uncooked cereals, and macroni products have been enriched with thiamine, ribo-flavin, niacin, iron and in some cases, calcium and vitamin D.

W.H.O. has defined food fortification as “a process where by nutrients are added to foods to maintain or improve the quality of the diet of a group, community or population”.

Food fortification is the procedure in which micronutrients (essential trace elements and vitamins) are added to the food. As a public health policy fortification can be carried out by the food manufacturers or by the governments to help people in combatting dietary deficiencies within a population. Fortification can be done in food even if these nutrients are originally present or not. However, it improves the nutritional status of a population by overcoming the deficiencies of micronutrients. Deficiency of micronutrients is known as hidden hunger which is a serious health risk. Access to safe and nutritious food is a must.Due to the lack of consumption of a balanced diet, adequate micronutrients are not supplied to the body. Therefore, there is a considerable loss of nutrients during the processing of food. One of the strategies to address this problem is fortification of food.

Introduction

In the existing socio-economic scenario, economic independence is considered as one of the main status indicator in the society. Women especially in rural areas are the deprived section of the society on account of their dependence on others for economic reasons. This necessitates generation opportunities so as to make them economically independent. Moreover, women’s contribution to national development is crucial. The process of development would be incomplete and lopsided, unless women are fully involved in it. Many innovations have failed due to non-satisfaction of women on the perceived attributes of innovations. So, it is necessary that they should be informed, trained, convinced of a technology primarily.

Farm women can’t emerge as a good entrepreneur, if they are not equipped with any skill, knowledge, education and information. So, research studies are essential to assess the training needs of them to become a successful entrepreneur. In order to know the training needs of farm women for entrepreneurial development, and the constraints faced by them to become a good entrepreneur.

Introduction
The global population is on track to surpass 9 billion by 2050, leading to a staggering 70% increase in the worldwide demand for food, feed, and fibre. This population growth is closely linked to significant shifts in lifestyle and consumption patterns, primarily driven by the accelerating pace of urbanization. As a consequence, it is anticipated that there will be a decline in the consumption of grains and pulses, coupled with a significant increase in the consumption of vegetables, fruits, meat, dairy, and fish. Aquaculture, a time-tested industry, stands out as a crucial source of high-quality protein for humanity (Nash, 2010; Gui et al., 2018). As our global population continues to expand, the challenges of resource scarcity and environmental degradation are becoming increasingly evident. Land resources alone are no longer sufficient to support the evolving needs of our society. Consequently, our oceans are emerging as a new frontier for human sustenance and development, with fish taking on a pivotal role as a source of high-quality protein and a fundamental dietary staple (Baiden and Bissiri, 2007). Over the past few decades, aquaculture has risen to become the fastest-growing sector within agriculture. Since 2013, its production has even outstripped that of wild fisheries (FAO, 2020). This formidable challenge presents particularly alarming situations in developing countries where poverty and hunger persist (World Bank, 2014). In such a context, fisheries and aquaculture are anticipated to play a vital role in ensuring nutritional security (Subasinghe, 2014). According to the FAO, food production will need to rise by 70% by 2050 to meet the rising demand brought on by population growth and dietary changes (FAO, 2009). By effectively using the limited water resources, the fisheries industry may serve to address this issue and contribute significantly to nutrition and food security. A significant source of nutrition, food, income, and livelihood for millions of people worldwide continues to be the fishing and aquaculture industries (FAO, 2016). Additionally, fish contribute to global food security by providing up to 17% of the protein consumed by the world's population (Bennet et al., 2018), and fishing is one of the most widely practised livelihoods worldwide (FAO, 2014). Although fish are the most diversified group of vertebrates, they are the second most threatened species after amphibians (Collen et al., 2014).
Freshwater ecosystems have been among the most endangered habitats worldwide in recent decades. Freshwater researchers have become more concerned about the devastation of riverine environments, changes in aquatic ecosystems, rapid decrease in water quality, and considerable decline in the variety and abundance of stream fishes. The presence, distribution, abundance, and diversity of fishes in the aquatic ecosystem are influenced and shaped by

Introduction

As India is the leading global economy with livestock contributing 4.66% in total GVA to Indian Economy (PIB, 2024) and ranks 1st in Milk Production, 2nd in Egg production, 5th in meat production (BAHS, 2024). Being the largest exporter of milk and meat in the world , this has led to the intensification of animal production due to the increasing demand of major livestock products (MLPs), which has led to an increasing overall use of antimicrobials. Antimicrobials are invariably used to preserve animal and public health, but also as growth promoters at a sub-therapeutic level. The overuse and misuse of antibiotics can contribute to antimicrobial resistance. The growing resistance to antimicrobial drugs could reverse the therapeutic benefits; animals’ resistance to antimicrobial drugs, reduces productivity and leads to economic losses. Unwanted antimicrobials residues may be present in products of animal origins, in animal waste contaminating soil and water and the environment. Seventy-five to ninety percent of antimicrobials used in livestock are excreted, mostly unmetabolized. AMR poses a serious threat to the safety and quality of animal origin food, food security and livelihoods. Unhealthy and unproductive animals are no longer able to generate food products of acceptable safety and quality for human consumption and can no longer contribute to income generation. Insufficient standards for residues in animal food products, reduces the livestock sectors potential of access to trade and increases public health risks (https://www.fao.org/antimicrobial-resistance/key-sectors/animal-production/ en/).

Introduction
Technology transfer and capacity building are critical to the advancement of agriculture, particularly in ensuring that research findings and innovations reach stakeholders efficiently. The Directorate of Extension (DoE) at Kerala Agricultural University (KAU) is a key player in this process, liaising with state development departments to drive technology dissemination in the agriculture and allied sectors. The DoE collaborates closely with development departments of agri and allied areas in the State, acting as a vital link to ensure that agricultural advancements reach the grassroots level. The Directorate also integrates institutional mechanisms to support this technology transfer. Through a network of Krishi Vigyan Kendras (KVKs) and several institutional mechanisms, the Directorate integrates new agricultural technologies into mainstream practices, focusing on both skill development and sustainable development strategies. It conducts workshops, seminars, and training programs focused on enhancing the skills of extension workers, farmers, and other stakeholders. The focus is not just on disseminating new technologies but also on building long-term capacity through skill development. This ensures that the stakeholders are well-equipped to implement the innovations in a way that promotes efficiency, productivity, and sustainability. In essence, the DoE at KAU is a driving force in modernizing agriculture in Kerala. Through its structured efforts in technology transfer, skill enhancement, and the promotion of sustainable practices, it enables the agricultural sector to keep pace with scientific advancements while ensuring that the benefits are accessible and applicable at the field level.
Initiatives / Interventions of DoE, KAU
The Directorate of Extension is crucial in bridging the gap between agricultural research and field-level application through various innovative initiatives. Key interventions include the popularization of agricultural technologies, primarily through farm-based production programs, Block Level Agricultural Knowledge Centres (BLAKC), and the Mukhamukham (face-to-face) Agro Clinic. The Directorate also focuses on capacity-building programs, entrepreneurship development, and ICT-enabled technology dissemination. Additionally, the Directorate supports vulnerable sections of society, develops Farmer Producer Organizations (FPOs), and implements state-funded development projects, contributing to the holistic growth of Kerala’s agricultural sector.

Introduction 
In order to ensure that future generations can prosper, sustainable development is an all-encompassing strategy that aims to strike a balance between social equity, environmental protection, and economic growth. The inclusion of genderresponsive policies is one of this agenda’s most important but often ignored components. Encouraging inclusive and sustainable development outcomes requires acknowledging and addressing the unique needs and contributions of different genders. Empowering women and other marginalized genders have positive effects on resilience, economic productivity, and environmental stewardship that go beyond local communities. Policies that are gender responsive aim to address systemic disparities by advancing equal opportunities and involvement in decision-making. These policies seek to empower marginalized groups while also utilizing their distinct viewpoints and skills to tackle urgent global issues. Women are important in agriculture and natural resource management, for example, so their input is essential in developing environmental policies that work. Gender considerations can be effectively integrated into development frameworks to produce more comprehensive solutions that lead to sustainable outcomes. In addition, promoting gender parity is not just a question of justice but also a critical component of sustainable development. Greater gender parity is associated with faster economic growth and better social outcomes in nations, according to a wealth of research. Entire communities gain when women have access to economic opportunities, healthcare, and education. In order to achieve sustainable development goals and make sure that no one is left behind, creating gender-responsive policies is therefore not just an ethical duty but also a practical necessity. In conclusion, examining the relationship between gender and sustainable development can help us better understand the many issues our world is currently facing. Gender-responsive policies should be given top priority so that we can help everyone reach their full potential and encourage creativity and resilience. This strategy opens the door for a more sustainable and inclusive future by promoting equitable development and bolstering our group’s capacity to handle social, economic, and environmental issues.

1. Introduction

A public library is a repository of diversified material that serves as the primary hub for community information the spread. It provides fair access to a wide range of information and data, meeting the diverse demands of users. Services must be inclusive, with information appropriate for all age groups and the incorporation of both classic materials and contemporary technologies across many mediums. In 1987, the ILA defined the purpose of public libraries, stating that they should serve as independent training centers for community activities. Public libraries play a pivotal role in fostering community engagement, welcoming all members to participate in various programs. Initially established by the public, these libraries later received government funding for expansion and other requirements. The systematic development of India's public library system ensued after the establishment of the Raja Rammohan Roy Library Foundation (RRRLF) in 1972.
