Precise nutrient supply
Nutrient requirements and dietary inter-relationships of energy, protein and amino acids, calcium, phosphorous, manganese, zinc, selenium, lysine, folic acid, biotin, vitamins A, E and D etc. for different classes and ages of poultry under tropical conditions have been established. Comparative efficacy of DL-methionine and methionine hydroxyl analogue(MHA) has been evaluated in the diet of broiler chickens and quails. The nutrient requirements for broilers and growing and laying quails have been successfully partitioned for developing feeding standards. These recommendations are being used by poultry farmers, feed manufacturers, researchers and Bureau of Indian Standards (BIS)
The database of nutritive/ feeding value and safe inclusion levels of alternate feed resources such as sunflower seed meal, maize gluten meal, rapeseed/mustard oil meal, rice bran, wheat bran, guar meal, cotton seed meal, tapioca, sunflower cake, niger meal, millets, molasses, apple pomace, broken rice, neem seed kernel, guar meal, meat meal, liver meal, slaughter house and hatchery wastes, poultry droppings, etc have been developed. Besides this, low cost feed formulae have successfully been developed for various poultry by incorporating alternate feed resources such as nutritious coarse cereals and agro-industrial by-products. Several ingredients in the category of nutritious cereals such as sorghum, pearl millet, finger millet, small millets and rice kani and residues such as rapeseed meal, cotton seed meal, sesame meal, groundnut meal, sunflower seed meal, safflower seed meal, toasted guar meal and niger meal etc. have been tested alone or in combination for their effective utilization in poultry rations.
Augmenting nutrient bio-availability
The nutritive value of feedstuffs has been augmented through various physical, chemical and biological treatments like water washing, wet processing (reconstitution with or without enzymes), dry processing (acidified sodium chlorite treatment for feed hygiene), roasting, autoclaving, alkali and acid treatments, fungal treatment and fermentation of the feed ingredients. Addition of microbial phytase in diets of broiler chicks, egg type chickens, guinea fowl and quails improved phosphorus utilization significantly that provided scope to reduce costlier di-calcium phosphate supplementation.
Enzyme supplementation was also found beneficial to improve utilization of sunflower seed meal, maize- finger millet or maize-sorghum based broiler starting and finishing diets. The solid substrate fermentation technique using Pleurotus sajarcaju improved the nutritive value of quail droppings. Similarly, using Aspergillus niger improved the nutritive value of toasted guar meal. The role of dietary supplementation of mineral chelates, prebiotics and probiotics, organic acids,feed sanitizers in enhancing the performance and immune response of poultry has also been established.
The safety aspects and feeding value of various genetically modified crops (Bt cotton, Bt brinjal Bt corn and quality protein maize) have also been assessed. A thin layer of chromatography procedure for determination of aflatoxin (B1) content in feeds and feedstuffs was developed. The Bureau of Indian Standards on the recommendations of the Livestock Feed Sectional Committee has adopted this method. The tolerance level of dietary aflatoxin in various domesticated avian species has been established. Efforts were made to alleviate detrimental effects of mycotoxins and pesticides through dietary modifications. Aflatoxins in the feed stuffs procurred by the Institute is regularly monitored.
Feed Formulation Software Developed
Window based unique computer software “MakeFeed” has been developed for formulation of low cost, efficient balanced feed for a wide variety of poultry like layer and broiler chickens, quails, guinea fowls, turkeys etc. using database developed in diversified agro-climatic conditions of India.
Developed feeding management packages of quails for growth and production suitable under different agro-climatic conditions for promoting quail production.
For the benefit of the small and marginal farmers and feed manufacturing industry, the division has frequently evolved scientific feed formulae based on the available feed materials in various parts of the country.
Developed low cholesterol chicken eggs enriched with omega-3 fatty acids through dietary interventions including supplimentation of copper sulphate, herbs, spirulina, statin, chromium and fish oil.
