Nutrient adjustments of broiler during hot weather and stressful conditions

During hot weather and stressful conditions, broiler chickens may experience physiological challenges that can affect their nutrient requirements and overall well-being. To mitigate the negative impacts of heat stress and maintain optimal performance, adjustments to broiler diets are often necessary. Here are some nutrient adjustments commonly implemented during hot weather and stress conditions:

Water: Adequate access to clean, cool water is crucial for broilers during hot weather. Increased water intake helps maintain hydration, regulate body temperature through evaporative cooling (panting), and support physiological functions. Ensure that water sources are readily available and regularly monitored to prevent dehydration.

Electrolytes: Electrolytes such as sodium, potassium, and chloride play a vital role in maintaining fluid balance and electrolyte equilibrium in broilers. During hot weather, electrolyte losses through panting and sweating increase, necessitating supplementation in the diet. Electrolyte supplements can help replenish lost electrolytes and support hydration.

Vitamins: Heat stress can impair vitamin metabolism and utilization in broilers. Supplementing diets with vitamins, particularly water-soluble vitamins such as vitamin C and certain B vitamins, can help support immune function, reduce oxidative stress, and maintain overall health during hot weather. Antioxidant vitamins such as vitamin E and selenium may also be beneficial in mitigating the effects of heat stress-induced oxidative damage.

Protein and Amino Acids: Heat stress can increase protein breakdown and amino acid requirements in broilers. Adjusting dietary protein and amino acid levels to meet increased demands for protein synthesis and repair can help maintain muscle mass, support immune function, and minimize performance losses during hot weather. Ensure that diets contain adequate levels of essential amino acids, especially lysine, methionine, and threonine.

Energy: Heat stress can reduce feed intake and increase energy expenditure in broilers as they divert energy towards dissipating heat to maintain body temperature. Adjusting dietary energy levels to compensate for decreased feed intake and increased metabolic demands can help maintain energy balance and prevent excessive weight loss. Consider increasing the energy density of diets by incorporating high-energy ingredients or adjusting the inclusion levels of fats and oils.

Feed Additives: Certain feed additives, such as probiotics, prebiotics, and enzymes, may help alleviate the negative effects of heat stress on broiler performance and health. Probiotics and prebiotics support gut health and digestive function, while enzymes improve nutrient digestibility and utilization, helping broilers maintain performance during periods of stress.

Acidifiers and Buffers: Acidifiers such as organic acids and buffers such as sodium bicarbonate can help maintain gut pH balance and reduce the risk of heat stress-induced gut disturbances, such as dysbiosis and bacterial proliferation. These additives may also enhance nutrient utilization and support overall gut health in broilers during hot weather.

Antibiotic Alternatives: In regions where antibiotic growth promoters are restricted or banned, alternative strategies for promoting gut health and mitigating heat stress-induced performance losses are needed. Nutritional strategies, such as optimizing diet formulation, improving feed quality, and incorporating natural feed additives with antimicrobial or immune-modulating properties, can help support broiler health and performance without relying on antibiotics.

By implementing these nutrient adjustments and management strategies, poultry producers can help mitigate the negative impacts of hot weather and stress conditions on broiler performance, health, and welfare. It’s essential to work with qualified nutritionists and veterinarians to develop customized nutritional and management plans tailored to the specific needs of broiler flocks and production systems. Regular monitoring of flock performance, environmental conditions, and feed quality is also critical for identifying and addressing issues promptly.
