Effects of Different Roughages on Growth Performance and Meat Quality of Hybrid Sheep
This paper studied the impact of different roughages on production performance and meat quality of hybrid sheep (Small-tail Han sheep and local sheep).90 rams at the age of 6 months with 27.5 kg +2.5 kg were divided into three groups randomly,each group of 30.The three groups were fed with maize straw,wild chinensis,chinensis respectively for 80 days.The results showed that the net weight in chinensis group was 9.5％ and 11.5％ respectively higher than those in maize straw group and wild chinensis group significantly,but no significant difference between maize straw group and wild chinensis group(P ＞0.05).The change rule of average daily gain was as the same as the net weight.There was no significant difference on the dry matter intake (P ＞0.05),but the feed weight ratios in maize straw group and wild chinensis group were 10.74％ and 11.37％ respectively higher than that in chinensis group significantly(P＜0.05).There were no significant difference on empty stomach weight,body weight and slaughter rate(P ＞0.05).The eye muscle area in chinensis group was 20.69 cm2,were 6.25％ and 4.44％ respectively higher than those in maize straw group and wild chinensis group (P＜0.05).The protein content of muscle in chinensis group was significantly higher than that in maize straw group (P＜0.05).The fat content in maize straw group and wild chinensis group were lower (P＜ 0.05).The moisture content of muscle in corn straw group was significantly lower than those in wild chinensis group and chinensis group(P＜0.05).
