Institute of Animal Nutrition (IAN) started functioning in April 1982 at Post Graduate Research Institute in Animal Sciences campus, Kattupakkam.


IAN is situated within PGRIAS campus which is 45th km of Grand South Trunk road from Chennai.


  • Identification of novel unconventional feeds and development of technology for feeding livestock.
  • To increase the feed efficiency in grazing animals through strategic supplementation and rumen manipulations.
  • Development of feeding strategy to sustain livestock during natural calamities.
  • Manipulation of dietary management for developing value added animal products/ functional foods for human beings.
  • Evaluation of newly released fodder crops in ruminants.
  • Formulation and evaluation of low cost complete rations.
  • Establishment of fodder bank.
  • Establishment of fodder seed production unit.
  • To evaluate feed or fodder to ascertain their quality.

  • Unconventional feed resources like Samai, Varagu, Soybean hulls, Mango-peel waste, Tapioca thippi and animal organic wastes were evaluated for ruminants.
  • Urea treatment of paddy straw, processing dehulled soyabean pods, dried fallen leaves and mature para grass were studied and recommended for feeding in ruminants.
  • Nutritive value of cultivated fodder crops like Stylosanthes hamata, Vigna unguiculata, Bajra Napier Hybrid grass (Co3) and Fodder Sorghum were evaluated and recommended for feeding in ruminants.
  • Top feed resources like Subabul (Leucaena leucocephala), Vagai (Albizzia lebbek), Peepal (Ficus religiosa), Banyan (Ficus bengalensis), Gliricidia sepium, Othiyan (Lannea coromadelica), Jack (Artocarpus heterophyllus) and Indian cork (Millingtonia hortensis) tree leaves were evaluated for dairy animals and small ruminants.

Teaching and Training

  • Training to under graduate students during their internship programme.
  • Post-graduate and doctoral programmes in Animal Nutrition.
  • Training to farmers on fodder production and compound feed manufacturing.

Technology Transferred
