Evaluation of unconventional oil cakes on in vitro Methanogenesis and fermentation of feed in rumen liquor of Buffalo

Abstract

In the present experiment four unconventional oil cakes (UOC) viz. karanj (Pongamia glabra), mahua (Madhuca indica), neem (Azadirachta indica) and castor bean (Ricinus communis) were tested for their effect on methane production, total gas production, IVTD, and ammonia nitrogen concentration. In Experiment I all the UOCs (Karanj, Mahua, Neem and castor bean) were evaluated for their feed fermentation in in vitro where 70% of UOCs and 30% maize was used as a substrate (50:50 Concentrate : Wheat straw). The methane production (ml/g DM) was significantly reduced (p
