Abstract

The experiment was conducted to study the effects of dietary selenium yeast on the production performance, nitrogen metabolism, slaughter performance and meat quality of Dorper×thin-tailed Han crossbred sheep. Forty Dorper×thin-tailed Han crossbred sheep (the average body weight was about 34 kg) were randomly assigned to 4 groups, with 10 sheep in each group. Sheep in the 4 groups were fed experimental diets which supplemented with 0 (control), 0.2, 0.4, 0.8 mg/kg selenium (the form was selenium yeast). The experiment lasted for 10 days for adaption, and 70 days for test. The results showed as follows:1) average daily gain was the highest and the feed/gain was the lowest when the selenium supplemental level was 0.2 mg/kg, and average daily gain was significantly higher than that in 0.4 and 0.8 mg/kg group (P<0.05). 2) It had no significant effects on intake nitrogen, fecal nitrogen, digestible nitrogen, nitrogen deposition and apparent nitrogen digestibility (P>0.05); urinary nitrogen was the lowest and the nitrogen utilization and nitrogen bioavailability were the highest when the selenium supplemental level was 0.2 mg/kg, and it had significant difference compared with 0.4 and 0.8 mg/kg groups (P<0.05). 3) When the selenium supplemental level was 0.2 mg/kg, the dressing percentage and net meat rate were all the highest, and they were significantly higher than those in control group and 0.8 mg/kg group (P<0.05). Selenium supplemental level had no significant influence on bone to meat ratio, eye muscle area and GR value (P>0.05), but with the increasing of selenium supplemental level, those indictors increased firstly and then decrease. 4) When the selenium supplemental level was 0.4 and 0.8 mg/kg, the slaughtered pH was significantly higher than that in the control group and 0.2 mg/kg group (P<0.05), but it had no significant influence on pH_{24 h} (P>0.05). The meat color in 0.4 and 0.8 mg/kg groups was significantly higher than that in 0.2 mg/kg and control groups (P<0.05). Meat shear force and cooked meat rate were significantly higher than those in other groups when the selenium supplemental level was 0.2 mg/kg (P<0.05). It is concluded that, when the selenium supplemental level is 0.2 mg/kg, it can significantly improve the dressing percentage, reduce the pH of meat and shear force, and it can improve the cooked meat rate of the sheep. But it can cause selenium poisoning of Dorper×thin-tailed Han crossbred sheep when the selenium addition level is 0.8 mg/kg.
