A trial was conducted at a commercial poultry farm in the United States to show the benefits of Avi-Bac WS on growth, feed efficiency, and mortality in broiler chickens

Procedure

1. A total of 800 male broiler chickens were used in a 44 day trial
2. Upon arrival the chicks were assigned to 16 pens of 50 chicks each providing eight (8) replicates per treatment.
3. All of the birds were fed a commercial broiler feeding program commonly fed in the United States
4. The starter feed containing 22% protein with the coccidiostat salinomycin and the growth promoter bacitracin was fed during days 0 – 21
5. The grower feed containing 20% protein and salinomycin and bacitracin was fed during days 22 – 41
6. The withdrawal feed containing 18% protein and bacitracin was fed during days 42 – 44
7. All of the birds were vaccinated against Marek’s Disease, Newcastle Disease and Infectious Bronchitus.
8. Eight (8) pens of birds served as the control treatment while the other eight (8) pens of birds served as the treatment group and received AVI-BAC WS on a continuous basis throughout the trial administered via the water at the rate of 25 grams per 100 liters of drinking water

A trial was conducted at a commercial poultry farm in the United States to show the benefits of Avi-Bac WS on growth, feed efficiency, and mortality in broiler chickens

Procedure

1. A total of 1,440 day-old male broiler chickens were used in a 46 day trial
2. Upon arrival the chicks were assigned to 24 pens of 60 chicks each providing 12 replicates per treatment.
3. All of the birds were fed a commercial broiler feeding program commonly fed in the United States
4. The starter feed containing 22% protein with monesin as the coccidiostat and bacitracin the growth promoter was fed during days 0 – 21
5. The grower feed containing 20% protein, monensin, and bacitracin was fed during days 22 – 41
6. The withdrawal feed containing 18% protein and bacitracin was fed during days 42 – 46
7. The treatment birds received the same feeding program as the controls
8. Twelve (12) pens of birds served as the control treatment while the other twelve (12) pens of birds served as the treatment group and received AVI-BAC WS on a continuous basis throughout the trial administered via the water at the rate of 25 grams per 100 liters of drinking water

Table 2: Evaluation of Avi-Bac WS on Broiler Chicken Performance

Results & Discussion

• The addition of AVI-BAC WS to the feeding program of the broilers resulted in a significant improvement in both final body weight and feed efficiency
• Body weight was increased by more than 1.75% while feed efficiency was also improved by 1.75%
• In addition, mortality was deceased to some extent in the birds fed AVI-BAC WS when compared with the control birds
• These results show the benefits, which can be obtained from the use of the combination of beneficial Lactobacilli and Bifidobacterium and digestive enzymes found in AVI-BAC WS to improve the performance of broiler chickens

A trial was conducted at a commercial poultry farm in the United States to show the benefits of Avi-Bac WS on growth, feed efficiency, and mortality in broiler chickens

Procedure

1. A total of 1,200 day-old male broiler chickens were used in a 45 day trial
2. Upon arrival the chicks were assigned to 24 pens of 50 chicks each providing 12 replicates per treatment.
3. All of the birds were fed a commercial broiler feeding program commonly fed in the United States
4. The starter feed containing 22% protein with salinomycin as the coccidiostat and bacitracin as a growth promoter, was fed during days 0 – 21
5. The grower feed containing 20% protein, salinomycin and bacitracin, was fed during days 22 – 41
6. The withdrawal feed containing 18% protein and bacitracin was fed during days 42 – 45
7. Twelve (12) pens of birds served as the control while the remaining twelve (12) pens served as the treatment group and were administered AVI-BAC WS via the drinking water on a continuous basis throughout the trial at the rate of 25 grams per 100 liters of drinking water

Table 3: Evaluation of Avi-Bac WS on Broiler Chicken Performance

Results & Discussion

• The addition of AVI-BAC WS to the drinking water of the broilers resulted in a significant improvement in both final body weight and feed efficiency
• The birds given the AVI-BAC WS showed a significant improvement in weight gain of 2.66%
• This increase in body weight was obtained with  a significantly improved feed efficiency when adjusted for body weight
• These results show that the administration of AVI-BAC WS, which assists in maintaining a healthy intestinal microflora to help maximize feed digestion and utilization and prevent digestive upsets, can be a valuable tool for improving the performance of broiler chickens
