ABSTRACT
The experimental Charolais crossbred cattle was conducted at a Hanh Cuong farm in An Giang prefecture, Vietnam. Four male cattles at 9 months were used in the Latin Square design (4 x 4) to determine the effects of neutral detergent fiber (NDF) on feed intake, nutrient digestibility and weight gain. The NDF levels used in the experiment were 43, 47, 51 and 55 (% dry matter intake) corresponding to NDF43, NDF47, NDF51 and NDF55 treatments. Dry matter intake per body weight of NDF43 (2.40%) treatments tended to (P>0.05) high compared to the NDF47 (2.20%), NDF51 (2.22%) and NDF55 (2.16%) treatments. Total metabolism energy inclined to decrease (P>0.05) from NDF43 to NDF55 treatments. It was 42.8, 38.4, 35.5 and 35.6 MJ/cattle/day (NDF43, NDF47, NDF51 and NDF55 treatments, respectively). The DM digestibility (%) of the NDF43 treatment (64.4%) was not various (P>0.05) with NDF47 (63.3%), NDF51 (61.4%) and NDF55 treatments (55.8%). However, DM digestibility value (kg/cattle/day) was not different (P>0.05) among NDF treatments. It was highest on the NDF43 (3.13 kg) and lowest on the NDF55 treatments (2.51 kg). Moreover, the CP digestibility value (kg/cattle/day) was not different (P>0.05) among NDF treatments. It was 0.466, 0.382, 0.415 and 0.392 g corresponding to NDF43, NDF47, NDF51 and NDF55 treatments. The average weight gain was the same as digestive CP in the present study. It was 552 g for NDF43 treatment and 517 g for NDF55 treatment. Therefore, the levels of NDF well for Charolais crossbred cattle in this study from high to low were 43, 47, 51 and 55%. The likely benefit of 51% NDF will be an increase in the utilization of fibrous roughage and daily weight gain from 9 to 12 months of age in the Charolais crossbred cattle diet.
