Biotin and early poult growth

Area of Science:

• Animal Science
• Poultry Nutrition
• Avian Physiology

Background:

• Poultry diets require precise nutrient balancing for optimal growth.
• Animal protein sources can influence nutrient bioavailability in turkey rations.
• Biotin is an essential vitamin for poultry metabolism and growth.

Purpose of the Study:

• To evaluate the impact of dietary animal protein levels on turkey poult growth.
• To determine the efficacy of biotin supplementation in different feed formulations.
• To assess the relationship between diet composition, biotin, and turkey performance.

Main Methods:

• Commercial Broad Breasted White male poults were fed isocaloric rations with varying animal protein (0%, 7.5%, 20%) from 0-8 weeks.
• Rations were either supplemented with biotin (220 mcg/kg) or not.
• Growth data were analyzed using analysis of variance.

Main Results:

• Biotin supplementation significantly enhanced growth (P ≤ 0.005) when animal protein was present.
• No growth response to biotin was observed in soybean-milo based diets.
• Feed efficiency correlated positively with improved growth rates.
• Mortality rates were not significantly affected by dietary treatments.

Conclusions:

• Biotin is crucial for turkey poult growth when animal proteins are included in the diet.
• Diet formulation, specifically the inclusion of animal protein, dictates the need for biotin supplementation.
• Optimizing biotin levels can improve feed efficiency and overall performance in young turkeys.
