ABSTRACT
This study was conducted at an experimental animal farm in An Giang University of Vietnam. Four male Saanen crossbred goats were used in the Latin Square design (4 x 4) to evaluate the effects of feed supplement combinations on feed intake, nutrient digestibility and nitrogen retention. The feed sources were finely ground and used in the experiment were Maize (Ma), Brocken rice (Br), Cassava chip (Ca) and Wheat (Wh). The proportion of combination (% dry matter intake) in two energy feed sources was 15% and 15% such as MaCa, MaWh, BrCa and BrWh. The results show that dry matter intake per body weight of BrWh (3.42%) and BrCa (3.40%) treatments tended to high compared to the MaCa (3.29%) and MaWh (3.08%) treatments. The organic matter digestibility (%) of BrCa was not different (P>0.05) with MaWh and BrWh but it was higher (P<0.05) than MaCa (76.0, 74.9, 74.0 and 71.2, respectively). However, nitrogen retention (g/animal/day) was different (P<0.05) among treatments. It was 8.84, 7.56, 6.87 and 6.62 g corresponding to BrWh, BrCa, MaCa and MaWh treatments. Moreover, average weight gain was the same as nitrogen retention in this study. Therefore, the energy feed combination that feed intake, nutrient value, nitrogen retention and daily weight gain well from high to low were BrWh, BrCa, MaCa and MaWh.
