Performances of Male Ongole Crossbred Cattle on Two Kind of Concentrate with Different Quality

Abstract

282 J.Indon.Trop.Anim.Agric. 33 [4] December 2008 The study was conducted to investigate performances of male Ongole crossbred cattle on given diet two kind of concentrate with different quality. Ten male Ongole crossbred cattle of 1.5-2 years old at about 253.10+12.34 kg of early body weight, they were divided two treatments, each consisted of five cattles. They were grown in individual pens for three months and fed Napiergrass (Pennisetum purpureum) and various concentrate (20%:80%). At the end of growing period, six cattles were slaughtered, each consisted of three cattles. Parameter observed were average daily gain, feed consumption, feed conversion ratio, percentage of carcass, component of carcass, chemical composition and physical characteristics of Longissimus dorsi and Biceps femoris muscles, feed cost per gain, and income over feed cost were tested by t-test. The results indicated that the concentrate various gave significant differences (P<0.05) on fat of carcass, fat of Biceps femoris muscle, tenderness of Longissimus dorsi and Biceps femoris muscles. It gave no significant differ-ences on average daily gain , feed consumption, feed conversion ratio, percentage of carcass, chemical composition (water, protein, fat and ash) of Longissimus dorsi and chemical composition (water, protein and ash) of Biceps femoris, and physical characteristics of Longissimus dorsi and Biceps femoris muscles.ഊFeed cost per gain T0 lowest than treatment T1 and income over feed cost of control T0 the best than treatment T1. The best fat of carcass, fat of Biceps femoris and tenderness of Longissimus dorsi and Biceps femoris of treatment (T1) than T0. The Ongole crossbred cattle had the economically of feed cost per gain and income over feed cost were more efficient of T0 than T1. Keywords : PO Cattle, Concentrate, Production Performance
