Abstract:The purpose of this study was to investigate the effect of culture of Acerermonium Terricola (ATC) on weight gain of whitefeathered broiler chickens. In this experiment, 200 1-day-old broiler chickens were randomly divided into 2 groups. The control group was fed the basal diet, and the Acerermonium Terricola group was fed with 0.20% ATC in the basal diet. The test period was 42 days. During this period, we recorded the body weight every week, analyzed the average daily gain, and counted the feed consumption of each group during the test period, and calculated the breeding benefits brought by the gain. The results showed that during the test period, compared with the control group, the average body weight of the Acerermonium Terricola group was significantly increased by 13.23% (P<0.01); the average daily weight gain was significantly increased by 13.53% (P<0.01). The profit of Acerermonium Terricola group was 14.06% higher than that of the control group. This shows that adding ATC in the feed can significantly increase the average daily gain of broilers. This increases breeding benefits and is beneficial to the antibioticfree and breeding of poultry animals.
