Abstract

This experiment was conducted to study the effects of Lactococcus lactococcus and it mixed with urea added in whole corn silage on the growth performance, slaughter performance and meat quality of Dorper sheep, to provide scientific basis for better utilization of whole corn silage and meat quality improvement in fattening sheep. Sixty healthy 2-month-old weaned male Dorper sheep with similar body weight[(23.0±1.5) kg] were selected and randomly divided into 3 groups with 4 replicates per group and 5 sheep per replicate. Sheep were fed no additives whole corn silage (control group), single addition of 0.1% Lactococcus lactococcus of whole corn fresh weight (probiotics group) and 0.1% Lactococcus lactococcus mixed with 0.5% urea mixture of whole corn fresh weight (mixed group) formulated total mixed rations, respectively. The pre-experimental period lasted for 10 days, and the experimental period lasted for 90 days. The results showed as follows:1) the final body weight and average daily gain of mixed group were significantly higher than those of probiotics group and control group (P<0.05), and the feed to gain ratio of mixed group and probiotics group was significantly lower than that of the control group (P<0.05). 2) The carcass weight, dressing percentage, net meat ratio, meat to bone and GR value of mixed group were significantly higher than those of the control group (P<0.05), and the pre-slaughter weight of mixed group was significantly higher than that of probiotics group and control group (P<0.05). 3) The muscle pH_{24 h} of probiotics group was significantly lower than that of the control group (P<0.05); the drop loss and water loss ratio in muscle of mixed group and probiotics group were significantly lower than those of the control group (P<0.05), and the cooked meat ratio was significantly higher than that of the control group (P<0.05). 4) The muscle ether extract content of mixed group and probiotics group was significantly higher than that of the control group (P<0.05), and the contents of lysine, phenylalanine, valine, histidine and arginine in muscle of mixed group were significantly higher than those of probiotics group and control group (P<0.05). In conclusion, feeding the single addition of Lactococcus lactococcus in whole corn silage total mixed ration cannot change the growth performance of Dorper sheep, feeding the addition of Lactococcus lactococcus mixed with urea in whole corn silage total mixed ration can improve the growth performance, decrease the feed to gain ratio, improve the carcass weight and dressing percentage et al, and it can increase the contents of ether extract and some amino acids in muscle, improve the meat quality of sheep.
