党参提取物对断奶仔猪生长性能、血清生化指标和肠道健康的影响
Effects of extract from Codonopsis pilosula on the growth performance, biochemical indexes in serum, and intestinal health of weaned piglets
目的 研究党参提取物对促进断奶仔猪生长及改善其肠道健康的影响,为改善仔猪健康和提高生猪养殖效益提供依据。 方法 选取21日龄性别、品种相同的三元断奶仔猪24头,随机分为3组,每组8个重复。对照组饲喂基础日粮,试验组分为低剂量组和高剂量组,分别在基础日粮中添加0.1%和0.2%的党参提取物,试验期间对其生长性能、血清生化指标和小肠结构进行测定。 结果 与对照组相比,党参提取物的低剂量组和高剂量组仔猪的平均日增质量分别显著提高了11.28%和20.00%,料重比分别显著降低了6.82%和9.85%;低剂量组和高剂量组的断奶仔猪血清谷草转氨酶活性分别显著降低了36.28%和39.24%,乳酸脱氢酶活性分别显著降低了28.07%和35.22%;试验组的谷草/谷丙比值显著降低。饲粮中添加党参提取物显著提高了断奶仔猪十二指肠、空肠和回肠的绒毛高度,并显著增加了十二指肠和空肠的绒隐比;但对断奶仔猪脏器指数无显著影响。 结论 在饲粮中添加党参提取物能够显著改善断奶仔猪的生长性能,减少肝脏损伤,并促进肠道健康。其中,以0.2%的添加比例效果最佳。
Objectives The effects of extract from Codonopsis pilosula on promoting the growth and intestinal health of weaned piglets were studied to provide a basis for improving the health of piglets and enhancing the efficiency of farming pigs. Methods 24 weaned piglets of the same sex and breed at 21 days of age were selected and randomly divided into 3 groups, with 8 replicates in each group. The control group was fed a basic diet, while the experimental groups were divided into a low-dose group and a high-dose group, with 0.1% and 0.2% extract from Codonopsis pilosula added to the basic diet, respectively. The growth performance, biochemical indexes in serum and the structure of small intestine were measured during the experiment. Results The average daily gain of weight in piglets in the low-dose and high-dose groups of extract from Codonopsis pilosula significantly increased by 11.28% and 20.00%, and the ratio of feed to weight significantly decreased by 6.82% and 9.85% compared with the control group. The activity of alanine aminotransferase in the serum of weaned piglets in the low-dose group and high-dose group significantly decreased by 36.28% and 39.24%, and the activity of lactate dehydrogenase significantly decreased by 28.07% and 35.22%. The ratio of glutamic straw to grain C in the experimental group decreased significantly. The addition of extract from Codonopsis pilosula to the feed significantly increased the villus height of the duodenum, jejunum, and ileum, and the ratio of pile to hide in duodenum and jejunum of weaned piglets. But it has no significant effect on the organ index of weaned piglets. Conclusions Adding extract from Codonopsis pilosula to the feed can significantly improve the growth performance, reduce liver damage, and promote intestinal health of weaned piglets. The best effect was achieved with a 0.2% addition ratio.
