In order to investigate the effects of Boluohui replacing Enramycin on piglet production performance, immune function, and intestinal health. 480 healthy 24 day old weaned ternary hybrid commercial piglets (half male and half female) with similar body weight were selected for the experiment, and randomly divided into 4 treatments, with 4 replicates per treatment and 40 piglets per replicate (see Table 1). Treatment 1: Feed a diet without any additives; Treatment 2: Feeding Boluohui; Treatment 3: Feeding with Enramycin; Treatment 4: Feed with Enramycin and Boluohui.

To investigate the effect of Boluohui extract on the slaughter performance of broiler chickens. 720 1-day-old AA broiler chickens were selected for the experiment and randomly divided into 8 treatments, with 6 replicates per treatment and 15 chickens per replicate. Adopting a 2 × 4 factorial design, i.e. Clostridium difficile (attack vs. no attack); On the basis of attacking and not attacking, four treatments were set up respectively, adding Boluohui extract at 0 mg/kg, 200 mg/kg, 400 mg/kg, and 800 mg/kg. The chicken cage samples were tested, and the composition and nutritional level of the diet were consistent among the treatments.

In order to study the effect of Boluohui extract on the production performance of commercial broiler chickens. 720 1-day-old AA broiler chickens were selected for the experiment and randomly divided into 8 treatments, with 6 replicates per treatment and 15 chickens per replicate. Using a 2 × 4 factorial design, i.e., with and without invasion of Clostridium difficile, four treatments were set up on the basis of invasion and non invasion, respectively, with the addition of Boluohui extract at 0 mg/kg, 200 mg/kg, 400 mg/kg, and 800 mg/kg. Try the chicken cage and freely eat and drink. The experimental period is 42 days.

In order to study the efficacy of Yiningyi in improving the production performance, nutrient and energy utilization efficiency, and meat production performance of commercial broiler chickens. 2240 1-day-old healthy AA broiler chickens were selected for the experiment and randomly divided into 2 treatments, with 5 replicates per treatment and 224 chickens per replicate. Treatment 1: Control group, fed with basic diet; Treatment 2: In the experimental group, a 50g/ton level of Yiningyi was added to the basic diet of the control group in treatment 1.

To investigate the efficacy of Meifei 3 in improving pork production performance and nutrient utilization efficiency. This study selected 80 healthy ternary hybrid commercial pigs weighing around 70 kg and randomly divided them into 2 treatments, with 4 replicates per treatment and 10 pigs per replicate. Treatment 1: Control group, fed with basic diet for fattening pigs; Treatment 2: In the experimental group, 500 mg/kg of Meifei No. 3 was added to the control group's diet. The experimental period is 8 weeks.

To investigate the effect of adding Yanning T1 to the diet under summer conditions on the production performance of meat rabbits, this experiment selected 2260 Yila meat rabbits at around 30 days old and added 1.0 g/kg of Yanning T1 to the basic diet. Adopting a single factor comparative experimental method. The pre trial period is 5 days, and the main trial period is 33 days.

In order to investigate the efficacy of Stress Ning C in improving the production performance, meat quality, and economic benefits of meat ducks. This study selected 40000 healthy 1-day-old meat ducks and divided them into two treatments. A control group of 20000 ducks were raised in a duck house and fed with a basic diet (nutritional level of commercial feed); The experimental group, consisting of 20000 individuals, was housed in two duck houses, with 10000 individuals per house. The control group was fed a basic diet plus 500 g/ton of stress Ning C.
