Study on microbial fermented litters in animal husbandry at household farm

Abstract

In this study, the effectiveness of reducing environmental pollution by using pro-biotics (VNUA Biomix) in animal husbandry at household farm level was evaluated. A total of 180 pigs (average weight of each pig was 21kg) were divided into 6 groups (30 pigs per group), of which 3 experimental pig groups were supplemented with pro-biotics into the pigsty and 3 control groups without pro-biotics. The studied results showed that adding pro-biotics to form the microbial fermented litters in the pigsty was able to reduce moisture, to keep the Coliform, E.coli and Salmonella density within permissible limits; fulfilling the requirements of bio-safety in the pig farms. There was no statistically significant difference in food consumption and weight gain between the experimental pigs and the control pigs. In addition, the use of pro-biotics to form the microbial fermented litters in the pigsty reduced the morbidity and mortality rates of the experimental pig; especially the complex respiratory diseases. The use of microbial fermented litter in the pig farms was also to reduce pollution in the common environment.
