Abstract

This study was conducted to investigate the effects of rumen-protected choline (RPC) on growth performance and plasma biochemical indices of lambs of Qianbeima goats. Twenty healthy lambs of Qianbeima goats aged 4 months with similar body weight were randomly divided to 2 groups {control group [(15.89±1.66) kg] and test group [(15.30±1.86) kg]} with 10 lambs in each group. Lambs in control group were fed a basal diet and those in test group were supplemented with 10 g/d RPC. The Trial lasted for 40 days, which consisted of a 10-day pretrial and a 30-day formal trial. The results showed that the supplementation of RPC: 1)significantly increased of the mean of dry matter intake during the whole period (P<0.05), and significantly reduced the ratio of feed to gain (P<0.05); 2) did not affect the apparent digestibility of dry matter, crude protein, ether extract and neutral detergent fiber (P>0.05), however, significantly increased those of acid detergent fiber and ash (P<0.05); 3) significantly increased nitrogen intake, retained nitrogen and absorbed nitrogen (P<0.05); 4) did not affect the mean of superoxide dismutase activity, as well as the concentrations of malondialdehyde, glucose, urea nitrogen, very low density lipoprotein, triglyceride, total cholesterol and creatinine in plasma during whole period (P>0.05). Under the conditions in the present study, the supplementation of 10 g/d RPC can improve growth performance but has no beneficial effects on plasma biochemical indices of lambs of Qianbeima goats.

Key words： rumen-protected choline; growth performance indices; plasma biochemical indices; lambs of Qianbeima goats
