【摘要】：为了研究不同饲养方式对松辽黑猪生长性能、血液生化指标及肠道消化酶活性的影响,试验选择25 kg左右的松辽黑猪60头,随机分为2组,分别采用舍饲和放牧的方式进行生长育肥试验,在体重达到100 kg时屠宰取样测定。结果表明:放牧组松辽黑猪日增重、料重比显著低于舍饲组(P0.05);放牧组血清中除三酰甘油含量显著低于舍饲组(P0.05)外,总蛋白、白蛋白、球蛋白、胆固醇、葡萄糖、谷草转氨酶、尿素氮的含量均差异不显著(P0.05);放牧组松辽黑猪肝脏的消化酶活性显著高于舍饲组(P0.05),而小肠食糜消化酶活性差异不显著(P0.05)。说明放牧饲养可达到节粮的目的,缓解人畜争粮的紧张现状,从而提高经济效益。
[Abstract]:In order to study the effects of different feeding methods on the growth performance, blood biochemical index and intestinal digestive enzyme activity of Songliao black pigs, 60 Songliao black pigs of about 25 kg were randomly divided into two groups. The growth and fattening experiments were carried out by means of house feeding and grazing respectively, and the slaughter sampling was measured when the body weight was 100 kg. The results showed that the daily gain of Songliao black pigs in grazing group was significantly lower than that in the room feeding group (P 0.05), the serum triglyceride content in grazing group was significantly lower than that in room feeding group (P 0.05), and the total protein, albumin, globulin, cholesterol, glucose and glutamic oxaloacetic transaminase in the serum of grazing group were significantly lower than those in room feeding group. There was no significant difference in the contents of urea nitrogen and the activity of digestive enzyme in liver of grazing group was significantly higher than that of the group fed in house, but the activity of intestinal chyme was not significantly different. It is shown that grazing and feeding can achieve the goal of saving grain, alleviate the tense situation of people and animals fighting for grain, and thus improve the economic benefit.
