饲粮添加不同来源的植物精油对仔猪生产性能的影响.

This study was to investigate the effects of plant essential oils from different sources on the growth performance of piglets, and to provide scientific basis for the application of plant essential oils in piglet feeding and feed production. In experiment 1, 384 PIC weaned piglets with body weight (7.90±0.46) kg were randomly divided into 4 groups with 4 replicates of 24 piglets each. The control group was fed commercial diet without antibiotic and plant essential oil, and the experimental group was fed essential oil R, essential oil A and essential oil B, respectively. The feeding trial lasted 32 days. In Experiment 2, 320 PIC nursery piglets with body weight (10.92±0.53) kg were randomly divided into 4 treatment groups with 4 replicates of 20 piglets each. The control group was fed commercial diet without antibiotic and plant essential oil, and the experimental group was fed a certain amount of essential oil R, essential oil A and essential oil B, respectively. The feeding trial lasted 23 days. The results of experiment 1 showed that compared with the control group, essential oils R and B could significantly reduce the F/G of weaned piglets (P<0.05), and the F/G of essential oil R was the lowest. In addition, only essential oil R can significantly reduce the diarrhea rate of weaned piglets (P<0.01). The results of experiment 2 showed that the F/G of nursery piglets with essential oil R was significantly lower than that of the control group and other experimental groups (P<0.05). During the experiment, there was no significant difference in diarrhea rate among all treatment groups (P>0.05). In addition, several essential oils had no significant effect on the hair condition and skin color of piglets (P>0.05). In conclusion, adding R essential oil to the diet can significantly improve the production performance of weaned and nursery piglets, and the effect is better than that of A essential oil products and B essential oil products.
