Abstract

This experiment was conducted to investigate the effects of dietary energy level on growth performance and serum biochemical indices of Laoshan dairy goats. Thirty Laoshan dairy goats with an average body weight of (18.43±0.76) kg were used in a single-factor randomized design and equally divided into 3 groups with 10 replicates in each group and 1 goat per replicate. Goats were fed diets with consistent crude protein, calcium and phosphorus levels, but with different energy levels (10.40, 11.47 and 12.51 MJ/kg, respectively). The experiment lasted for 100 days consisted of a 10-day pre-experimental period and a 90-day experiment period. The results showed as follows:1) dry matter intake of goats at 7 and 8 months of age in 10.40 MJ/kg group was significantly lower than that in 12.51 MJ/kg group (P<0.05), and there was no significant difference at 9 months of age among groups (P>0.05). 2) Body weight of goats at 8 and 9 months of age in 10.40 MJ/kg group was significantly lower than that in 11.47 and 12.51 MJ/kg groups (P<0.05), and in 10.40, 11.47 and 12.51 MJ/kg groups compared with that before the test was increased by 141.22%,157.40% and 158.09%. Chest circumference and abdominal circumference of goats at 8 months of age in 10.40 MJ/kg group were significantly lower than those in 12.51 MJ/kg group (P<0.05), and chest circumference and rump length of goats at 9 months of age in 10.40 MJ/kg group were significantly lower than those in 12.51 MJ/kg group (P<0.05). 3) Serum urea nitrogen content in 10.40 MJ/kg group was significantly higher than that in 11.47 and 12.51 MJ/kg groups (P<0.05). Serum total cholesterol content in 10.40 MJ/kg group was significantly lower than that in 12.51 MJ/kg group (P<0.05). Serum triglyceride content in 10.40 MJ/kg group was significantly lower than that in 11.47 (P<0.05) and 12.51 MJ/kg groups (P<0.01). Overall, considering feed cost, dietary digestible energy level at 11.47 MJ/kg is the best for Laoshan dairy goats.
