The latest Brazilian Tables for Poultry and Swine (BT 2024) nutritional program significantly improved broiler performance and economic returns. This updated program led to better feed conversion and higher net revenue compared to older standards.
Area of Science:
- Animal Science
- Poultry Nutrition
- Agricultural Economics
Background:
- Nutritional recommendations for broiler chickens require regular updates to optimize production efficiency.
- Previous nutritional programs may not reflect current genetic potential or feed ingredient availability.
Purpose of the Study:
- To evaluate the impact of updated nutritional programs on broiler chicken growth, carcass traits, body composition, and economic profitability.
- To compare the efficacy of the Brazilian Tables for Poultry and Swine (BT) 2024, BT 2017, BT 1983, and Cobb 2022 nutritional programs.
Main Methods:
- A 2x4 factorial experiment with 1,600 broiler chickens, examining sex (male/female) and four nutritional programs.
- Growth performance, carcass traits, and body composition (using DXA) were assessed.
- Statistical analysis included ANOVA and SNK tests; economic analysis evaluated feed costs and revenues.
Main Results:
- An interaction between sex and nutritional program affected performance, carcass traits, and body composition.
- BT 2024 and BT 2017 improved performance and carcass traits over BT 1983; BT 2024 showed the lowest feed intake and best feed conversion ratio.
- BT 2024 yielded the highest net revenue due to reduced feed cost per kg of ADG, despite BT 2017 having higher gross revenue.
Conclusions:
- The BT 2024 nutritional program demonstrates superior broiler performance and economic efficiency.
- Continuous updating of nutritional recommendations is crucial for maximizing broiler production and profitability.
