Effects of microbial enzyme synergistic fermentation feed on growth performance and blood biochemical indicators of weaned piglets
This experiment aims to investigate the effects of microbial enzyme co fermentation feed on the growth performance,nutrient apparent digestibility,and blood biochemical indicators of weaned piglets. 96 body weight(7.61±0.58)kg 28-day-old weaned piglets were randomly divided into a control group(CT group),a lactic acid bacteria fermentation group(48 hour fermented feed),an enzyme preparation group(enzyme preparation),and a bacterial enzyme synergistic fermentation group (48 hour bacterial enzyme synergistic fermented feed). Each group had 4 replicates,with 6 pigs per replicate. The experimental period is 4 weeks. The results showed that:(1)Compared with the control group,the final weight and average daily gain of the lactic acid bacteria fermentation group and the bacterial enzyme synergistic fermentation group were significantly higher than that of CT group(P<0.05);(2)Compared with the control group,the crude protein and phosphorus digestibility of the experimental group was significantly higher than that of CT group(P<0.05),while the crude fat digestibility,organic matter digestibility,and calcium digestibility of the experimental group were higher than those of CT group(P>0.05);(3)The total protein and serum urea nitrogen levels in the lactic acid bacteria fermentation group and the bacterial enzyme synergistic fermentation group were significantly higher than those in the control group(P<0.05).From the above,it can be concluded that the treatment of bacterial enzyme co-fermentation can increase the average daily gain,the digestibility of crude protein and phosphorus,the level of serum total protein and serum urea nitrogen. It can improve the growth performance and health level of piglets.
