Abstract:This experiment was conducted to study the influences of Flammulina velutipes residue on growth performance, body size indexes, feed behavior and ruminant behavior of lambs. Twelve healthy male lambs of house feeding Hu sheep with similar body weight of (18.60±1.15) kg were randomly divided into 2 groups with 6 lambs per group. Lambs in the control group were fed a basic diet, and others in the Flammulina velutipes residue group were added 30% Flammulina velutipes residue equivalent substitution of roughage in basic diet. The pre-experimental period lasted for 7 days, and the experimental period lasted for 60 days. The results showed as follows:1) the average total weight gain and average daily gain of lambs of Flammulina velutipes residue group were significantly higher than those of the control group (P<0.05). There were no significant differences in body height, body oblique length, chest circumference and cannon circumference of lambs between two groups (P>0.05). 2) There were no significant differences in average daily feed intake, average daily intake time and drinking water times and time of lambs between two groups (P>0.05). The defecation and urination times of lambs of Flammulina velutipes residue group were significantly higher than those of the control group (P<0.05 or P<0.01), the wandering time was significantly lower than that of the control group (P<0.05), and the sleeping time was significantly higher than that of the control group (P<0.05). 3) The ruminant cycle and ruminating time of lambs of Flammulina velutipes residue group were significantly higher than those of the control group (P<0.05), and the food pellet chewing times, every food pellet chewing times and every food pellet chewing time of lambs of Flammulina velutipes residue group were significantly higher than those of the control group (P<0.01). In conclusion, adding 30% Flammulina velutipes residue to the roughage in diets have positive effects on growth performance, feed behavior and ruminant behavior of lambs.
