Feed Intake and Feed Conversion Ratio of Ongole Crossbred Cattle Fattened at Different Ages and Feed

This research aimed to determine the effect of dietary treatments and age on fattening process in cattle. Thirty-six Ongole crossbred cattles were allotted into two different three groups, with six replications for 24 weeks period, 4 preliminary followed by 20 data collection at Beef Cattle Research Station (BCRS). The experimental design was completely randomized a 2 x 3 factorial. cattle placed individual pens had ad-libitum access water feed, feeds elephant grass concentrate (25:75). parameters observed liveweight, DM intake, feed conversion ratio, efficiency, IOFC, BCR. Liveweight measured every fortnight intakes daily. results showed that 10% substitution DGGS cassava did not affect all observed. Age total gain. Total intake increased age, although percentage liveweight efficiency decreased increasing age. All 18 months old group better than those 30- 42-months groups. It concluded PO most profitable.
