Effects of the Fermented Composite Medicinal Plant Agent on the Growth Performance,Blood biochemical Indices,and Antioxidant Properties of the Broilers
400 test chicken (1-day-old AA broilers) were randomly selected and divided into 4 groups. The test chicken in the blank control group was only fed with the basal diet,the test chicken in the test groups Ⅰ,Ⅱ and Ⅲ were fed with the basal diet+0.1％ gentamycin,the basal diet+0.2％ compounded Chinese herbal medicine preparation,the basal diet+0.2％ fermented compounded Chinese herbal medicine preparation respectively. The effects of the fermented compound medicinal plant agent on the growth performance,blood biochemical indices and antioxidant properties of broilers were investigated. The results showed that at 1-25 day-age,compared with control group,the daily weight gain of broilers in test groups Ⅰ,Ⅱ and Ⅲ increased by 2.24％,2.24％ and 4.50％ respectively (P<0.05),feed-to-weight ratio all decreased by 2.21％ (P<0.05). At 26-49 day-age,the daily weight gain of the broilers in test groups Ⅰ,Ⅱ and Ⅲ increased by 2.31％,4.52％ and 4.99％ respectively (P<0.05),the daily weight gain of broilers in test group Ⅲ increased by 0.45％ and 2.62％ respectively compared with that in test groups Ⅱ,Ⅰ.The feed-to-weight ratio of the broilers in test group Ⅲ decreased by 0.62％ compared with that in test groups Ⅱ,Ⅰ (P<0.05). Compared with the control group,the crude protein utilization rate of the broilers in test groups Ⅰ,Ⅱ and Ⅲ increased by 1.86％,1.77％ and 3.46％ respectively (P<0.05),and the crude protein utilization rate of the broilers in test group Ⅲ in-creased by 1.66％ and 1.57％ respectively (P<0.05) compared than that in test group. The crude fat utilization rate of the broilers in test groups Ⅰ,Ⅱ and Ⅲ increased by 0.98％,0.97％,1.76％ respectively (P<0.05) compared with that in the control group. The crude fat utilization rate of the broilers in test group Ⅲ increased by 0.77％ (P<0.05) compared with that in the test group Ⅰ. In conclusion,the ad-dition of fermented compound medicinal plant preparations could improve the growth performance and antioxidant properties,reduce the feed-to-weight ratio,and improve the morbidity,diarrhoea rate and mortality.
