Response of Bali cattle compared to Bali crossed Angus on concentrate feeding

Bali cattle is one of Indonesian native cattle that has potential as a premium beef. Unfortunately, they have a small frame size. Crossing with Angus breed is expected improve the growth, frame size, and meat quality but it needs better feed quality, for example by adding feed concentrate. Fourteen Bali crossed Angus and fourteen Bali cattle at 9-15-month-old were used in this research. Trial was conducted for 30 days in an individual cages. Diet was consisted of roughage (80) and concentrate (20) (dry matter based) and contained 11 crude protein (CP) and 56.2 total digestible nutrients (TDN). The concentrate composition was rice bran (55.31) and copra cake (44.69). Results showed that total dry matter intake of Bali cross Angus cattle (5.19 kg/head/day or 2.92 body weight) was higher than Bali cattle (3.39 kg or 2.83 body weight). Crude protein intake was no significant difference (0.26 kg vs. 0.26 kg), but TDN intake was lower (1.43 kg vs. 1.90 kg). Feed intake had a positive correlation with average daily gain (0,52 vs. 0.12 kg/head/day). Bali crossed Angus cattle was more adaptive concentrate feed introduction.
