摘 要:
旨在探讨日粮中添加不同比例的牡丹籽饼对生长肥育猪生长性能、消化性能和屠宰性能的影响。选取体重为50 kg左右的杜长大三元杂交生长肥育猪40头,随机分为4组,试验Ⅰ组为对照组,饲喂基础日粮,试验Ⅱ组、试验Ⅲ组、试验Ⅳ组的日粮中分别添加2%、5%、8%的牡丹籽饼,各组日粮营养水平一致;预试期10 d,正试期35 d,试验结束时测定并比较各组育肥猪的生长性能、消化性能及屠宰性能指标。结果表明,试验Ⅲ组和试验Ⅳ组的平均日增重分别达到972.00 g和974.29 g,与对照组相比差异显著(P<0.05);料重比以试验Ⅲ组为最低,试验Ⅳ组次之,但组间差异不显著(P>0.05);日粮干物质、粗蛋白质、粗脂肪的消化率以试验Ⅲ组最高,粗纤维的消化率以试验Ⅰ组最高,组间差异均不显著(P>0.05);4组实验猪只在宰前活重、胴体重、屠宰率和眼肌面积上差异不显著(P>0.05)。在生长肥育猪日粮中添加不同比例的牡丹籽饼,对其生长性能、消化性能及屠宰性能没有不良影响,且有提高的趋势,综合考虑添加量以5%左右为宜。

摘 要:
This experiment was conducted to assess the effects of dietary supplementation of peony seed cake with different proportions on growth, digestion and slaughter performance of growing-finishing pigs. A total of 40 crossbred(Duroc×Yorkshire×Landrace) pigs with approximately 50 kg of body weight were randomly assigned to four groups: experiment Ⅰ group served as control and fed basil diet, experiment Ⅱ, Ⅲ, Ⅳ groups received 2%, 5%, 8% of peony seed cake supplementation in basil diet;different groups had the same nutrition level of the diet, and the pre-experiment and formal experiment lasted for 10 days and 35 days, respectively; at the end of the experiment, the indexes associated with growth, digestion and slaughter performance of the growing-finishing pigs in different groups were determined and statistically assessed. The results demonstrated that the average daily gain of experiment Ⅲ and Ⅳ groups reached up to 972.00 g and 974.29 g respectively and was significantly higher than that of control group(P>0.05); the lowest feed/gain ratio was observed in experiment Ⅲ group followed by experiment Ⅳ group, but no group differences were found(P>0.05); the experiment Ⅲ group had the highest digestibility of dry matter, crude protein and crude fat, and the experiment Ⅰ group had the highest digestibility of crude fiber, but no group differences in the digestibility of nutrients were observed(P >0.05); there were no significant differences in pre-slaughter live weight, carcass weight, dressing percentage and eye muscle area between different groups(P >0.05). Taken together, we concluded that the dietary supplementation of peony seed cake has no affection on growth, digestion and slaughter performance of growing-finishing pigs;furthermore, an improving tendency of the associated indexed is observed, and the 5% supplementation proportion of peony seed cake is recommended by this study.
