Abstract

This experiment was conducted to study the effects of Lactobacillus plantarum and it mixed with urea added in whole corn silage on growth performance, slaughter performance and muscle quality of Dorper 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 with no additives whole corn silage (control group), single addition of 0.1% Lactobacillus plantarum of whole corn fresh weight (probiotics group) and 0.1% Lactobacillus plantarum 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 (FBW), average daily weight (ADG) and average daily feed intake (ADFI) of mixed group were significantly higher than those of probiotics group and control group (P<0.05), and there was no significant effect on feed to gain ratio (F/G) among all groups (P<0.05). 2) The pre-slaughter weight and dressing percentage of mixed group were significantly higher than those of probiotics group and control group (P<0.05), the carcass weight and kidney percentage of mixed group were significantly higher than those of the control group (P<0.05), the heart and liver percentages of the control group were significantly lower than those of mixed group and probiotics group (P<0.05), and the eye muscle area and GR value of probiotics group were significantly higher than those of mixed group and control group (P<0.05). 3) The pH, drop loss, water loss ratio and meat color of brightness (L^*) and yellowness (b^*) values in muscle of probiotics group were significantly lower than those of the control group (P<0.05), but the cooked meat ratio was significantly higher than that of the control group (P<0.05). The contents of dry matter, ether extract and crude protein in muscle of mixed group were significantly higher than those of the control group (P<0.05), and the contents of threonine, phenylalanine, leucine, isoleucine, valine, arginine, cysteine, tyrosine, glutamate, glutamate, glycine and proline in muscle of mixed group were significantly higher than those of the control group (P<0.05). In conclusion, the single addition of Lactobacillus plantarum in whole corn silage total mixed ration cannot change the growth performance of Dorper sheep, and the addition of Lactobacillus plantarum mixed with urea in whole corn silage total mixed ration is favorable for improving the growth performance, slaughter performance and muscle quality of Dorper sheep.

Key words： Lactobacillus plantarum; whole corn silage; Dorper sheep; growth performance; slaughter performance; muscle quality
