Effect of Radix pulsatillae ultrafine powder on diarrhea intervention of river buffalo calves
The purpose of this experiment was to investigate the effects of different levels of Radix pulsatillae ultrafine powder on average daily gain,diarrhea,blood routine,and blood immune indexes of river buffalo calves.120 seven-day-old healthy calves were randomly divided into four groups,30 repelicates in each group and one calf in each replicate.Calves in the control group were fed basic milk(without Radix pulsatillae ultrafine powder),the group Ⅰ,group Ⅱ,and group Ⅲ were fed 5,10,and 15 g/(calves·d)Radix pulsatillae ultrafine powder,respectively,and the milk amount per meal of each calf increased with age by about 2.5～5.0 kg.The experimental period was 30 days,and the colostrum period was seven days.Milk with Radix pulsatillae ultrafine powder was fed continuously from the first day to the third day after the colostrum period,and basic milk was fed from the fourth day to the seventh day.Three cycles of feeding were carried out after the colostrum period.The results showed that the final weight and average daily gain of calves in the group Ⅲ were significantly higher than those in the control group and group Ⅰ(P<0.05).The diarrhea rate in the group Ⅰ was the highest,which was 20.00%.The diarrhea rate in the control group was 16.67%.The diarrhea rate of the group Ⅱ and group Ⅲ was 13.33%.The mortality rate of diarrhea in the control group was 3.57%,and that in the group Ⅰ,group Ⅱ,and group Ⅲ was 0.There was no significant difference in blood routine and blood immune indexes such as WBC,HGB,IgG,IgA,IgM among the groups(P>0.05).The results showed that adding 10～15 g/(calves·d)Radix pulsatillae ultrafine powder regularly could increase daily gain and reduce diarrhea of calves.
