Each group was fed for 6 wk with diets that contained dried mulberry leaves at 0, 5, 10, or 15%. [ Result] The rate of egg production, egg weight, egg mass, feed intake, body weight, blood glucose level, total blood cholesterol, and triglyeride, and cholesterol of egg yolk in the dietary mulberry leaf groups were lower than the 0% mulberry leaves group. Compared with the 0% group, the feed required to produce 1 kg of eggs was 12.8% more in the 15% dietary mul- berry leaf group. Body weight and cholesterol of egg yolk decreased significantly in this group (P 〈0.05). Blood glucose and triglyerides in the 15% dietary mulberry leaf group were significantly lower than in the 0 and 5% dietary mulberry leaf groups (P 〈0.05). Yolk color in all treatments was higher than in the 0% group (P 〈0.05), and Roche pigmentation score increased by 2 -2.9. One -deoxynojirimycin was detected from egg white in all treatments, and its content varied significantly between groups ( P 〈0.05). E Conclusion] This study reflected the hypoglycemic and lipid -low- ering effects of mulberry leaves on productive performance and egg quality in laying hens. The suggested proportion of dietary mulberry leaves was 5% -10%.展开更多

Results showed that the maximum yield of total flavonoids (6.1% ) was obtained from mulberry leaves with addition of 45 times the volume of water by ultrasonic extraction at 55 ℃ for three times, 55 min each. According to the verification test, the optimized technical process was reasonable and feasible with high stability.展开更多

[...[Objectives] This study was conducted to investigate the effect of mixed silage of mulberry branches and leaves on the production performance of Tan Han hybrid mutton sheep and explore the feasibility in production. [Methods] Twenty-six Tan Han hybrid mutton sheep were selected and divided into two groups, 13 in each group. The experimental group was fed with the mixed silage and the control group(CK) was fed with whole-plant corn silage. [Results] The average daily weight gain per sheep of the experimental group was 9.2% higher than that of the CK(P<0.05), and the feed conversion ratio was decreased by 6.98%(P<0.05). The average daily weight gain per sheep in the 30 d improved the gross profit by 7.75 yuan, which meant an increase of 16.32%. [Conclusions] The mulberry mixed silage is feasible in the production, and it could significantly improve the production performance of the hybrid mutton sheep.展开更多
