OFT-3 (ANIMAL SCIENCE)

1

Title of On farm Trial

Effect of locally available feed resources (Paddy) on milk production and quality of dairy animals.

2

Problem diagnose

Banka is paddy and wheat grown area. Farmers are feeding paddy or wheat as grains and oil cakes in limited amount (100-250g) which is the main source of protein fat and minerals. Low productivity, anestrous and repeat breeding are because of deficient or excess of some nutrients. Therefore we formulate  ration based on paddy or wheat including cakes to fulfill protein requirement providing a least cost balanced feed from locally available feed resources paddy and wheat.

In Banka district mainly paddy straw used as dry fodder Amarpur, Bounsi, Banka block of Banka district  having more than 15 sugarcane mill for molasses production. Each mill produce at least 20T sugarcane bagasse and used as fuels. Due to lack of grazing grasses from the of month February to May More than One lakh Dairy cattle (ND) were migrated to west Bengal and others areas from Katoria, Chanan, Belhar and Shambhuganj block of Banka district. So, trail have designed to use of sugarcane bagasse for animal feed in Banka district.
