Effects of Plant Extracts Replacing Anti-coccidia Drugs on Broiler Performance and Fecal Coccidian Count
The experiment aimed to investigate the effect of plant extracts replacing anti-coccidian drugs on growth performance and fecal coccidian count in broilers.A total of 234 1-day-old healthy yellow-feath-ered broilers were selected and randomly divided into 3 groups,with six replicates in each group and 13 broiler chickens in each replicate.The test period was 55 days.The control group was fed the basic diet,the anticoccodidian group was fed the basic diet+500 g/t dinitolmide,and the plant extract group was fed basic diet+500 g/t plant extract.The results showed that the average daily gain of the anti-coccidian es-sential oil group from 1 to 21-day-old chicks was significantly higher than that of the anti-coccidian drug group(P＜0.05),and the feed to gain ratio was significantly lower than the drug group(P＜0.05).In the overall period,there was no significant difference in daily weight gain and feed intake between plant extract group and anti-coccidian drug group,and the feed to gain ratio decreased by 6.30％,so did the mortality rate by 10.26％.The number of fecal coccidia at 33 days in the plant extracts was significantly lower than that in the anticoccidia group and control group(P＜0.05).In conclusion,plant extracts can be used as al-ternatives for anti-coccidian drugs and have promising applicable prospect in animal husbandry.
