| 摘要 | [Objective] The paper was to investigate the impact of plant extracts replacing anticoccidial drugs on growth performance and fecal coccidia count in broilers. [Method] A total of 234 one-day-old healthy yellow-feathered broilers were selected and randomly divided into 3 groups, with 6 replicates in each group and 13 broilers in each replicate. The test lasted for a total of 55 d. The control group was fed the basic diet, the anticoccidial group was fed the basic diet + 500 g/t dinitolmide, and the plant extract group was fed the basic diet + 500 g/t plant extract. [Result] The daily gain of the plant extract group from 1 to 21 days of age was significantly higher than that of the anticoccidial drug group (P<0.05), and the feed/gain ratio was significantly lower than that of the anticoccidial drug group (P<0.05). There was no significant difference in daily gain and feed intake between the plant extract group and the anticoccidial drug group from 1 to 55 days of age (P>0.05), and the feed/gain ratio was reduced by 6.30% and the mortality and culling rate was reduced by 10.26%. The number of fecal coccidia at 33 days of age in the plant extract group was found to be significantly lower than that observed in the anticoccidial group and the control group (P<0.05). In conclusion, the administration of plant extracts resulted in a notable enhancement in the growth performance of chicks aged 1-21 days, when compared with the use of anticoccidial drugs. No significant difference was observed in growth performance between the plant extract and the anticoccidial drugs from 1 to 55 days of age. The administration of plant extracts resulted in a notable reduction in the fecal coccidia count. [Conclusion] Plant extracts may serve as viable alternatives to anticoccidial drugs and show promise for application in animal husbandry. |
