饲粮添加发酵中药渣对母猪繁殖性能与子代生长性能的影响

Effects of Dietary Supplementation with Fermented Herb Residues on Reproductive Performance of Sows and Growth Performance of Their Offspring

为了探讨中药渣在母猪饲粮中添加的可行性,试验选用2-4胎次、预产期相近的健康二元母猪60头,随机分为对照组、中药渣组和发酵中药渣组,比较研究发酵前和发酵后中药渣对母猪繁殖性能和仔猪发育的影响。结果表明：与对照组相比,发酵中药渣组产仔数、产活仔数和断奶平均日增重均有所增加,断奶窝增重和哺乳仔猪腹泻率显著增加,母猪背膘损失有所降低;中药渣组木乃伊数略有增加,仔猪腹泻率明显增加。由上可见,饲粮中添加发酵中药渣制剂虽然在短期内造成仔猪一定程度的腹泻,但可提高母猪繁殖性能和仔猪生长性能。

This study was conducted to explore the possibility of the herb residues （HR） supplementation in sow diets. Sixty healthy crossbred sows with close expected date of delivery during the 2-4 parities were used and randomly allocated to one of three groups, representing the control group, HR group and fermented HR group, to determine the effects of the HR and fermented HR on reproductive performance of sows and growth performance of their offspring. The results showed that, compared with the control group, the litter size, alive litter size, and average daily gain of weaned piglets from the FHR group displayed a trend toward increasing;the litter weight gain of weaned piglets and diarrhea rate of suckling piglets significantly increased;the backfat loss of sows displayed a trend toward decreasing. The mummy size from the HR group displayed a trend toward increasing, and the diarrhea rate of piglets significantly increased compared with the control group. These findings suggested that dietary supplementation with the fermented HR results in a certain degree of diarrhea of suckling piglets, but improved the reproductive performance in sows and growth performance of piglets.
