ABSTRACT
In Indonesia, the cost of feed for livestock industry is increasing day by day and now researchers are trying to use agriculture waste to overcome the scarcity of feed. In current experiment, corn cobs, an agriculture waste, were ammoniated with urea and used in the feed of Brahman cross cattle to determine their effects on the performance. This research was conducted between October and December 2021, involving Brahman cross cows (n=9) aged 8-12 months. The study utilized a randomized block design (RBD) with three treatments and three groups. The treatments administered were as follows: P0: 80% basal feed + 20% corn cobs without ammonia (0% urea), P1: 80% basal feed + 20% ammoniated corn cobs (2.5% urea), and P2: 80% basal feed + 20% ammoniated corn cobs (5% urea). The variables observed included body weight gain, feed consumption, feed conversion, and income over feed cost (IOFC). The results indicated that there were no significant differences in feed consumption (P0:7.38 ± 1.26 kg; P1:7.32±1.47 kg; P2: 7.26 ± 2.10 kg), body weight gain (P0: 0.85 ± 0.16 kg; P1:0.97±0.13 kg; P2: 0.90 ± 0.23 kg) and feed conversion (P0: 8.79 ± 1.62; P1:7.56±1.22; P2: 8.04 ± 0.35) among the treatments P0, P1, and P2, respectively; however IOFC was higher (p<0.05) in P1 (Rp. 34.054) and P2 (Rp. 30.620) as compared to P0 (Rp. 28.635) groups. These results demonstrated that the ammoniated corn cob addition in the ration of Brahman cross cattle is beneficial in terms of improved IOFC
