Precision Nutrition Strategies for Poultry Farming

What is Precision Nutrition Management?

Precision Nutrition Management in broiler chicken farming represents a paradigm shift. Traditionally, broilers are fed through three to five diet phases, leading to nutrient imbalances. While increasing phases boosts efficiency, it’s costly. Recent technologies enable blending feeds to meet daily nutrient needs.

This review assesses studies on varied feed phases’ impact, exploring extreme precision nutrition—daily diets matching broilers’ requirements. Precision-feeding technology promises enhanced efficiency, cost reduction, and sustainability. Beyond nutrition, it offers adaptability to environmental changes, market shifts, and farm-specific adjustments.

Nutrient Requirements for Poultry

Poultry require at least 38 nutrients in their diets in appropriate concentrations and balance. These include water, energy, protein, amino acids, vitamins, minerals, and other nutrients and additives. The nutrient requirements of poultry vary depending on many factors, such as species, age, sex, breed, production level, environmental conditions, and health status.

The most recent values of nutrient requirements for poultry were published by the National Research Council (NRC) in 1994. However, these values are based on experimental data and do not include a margin of safety or account for variations in nutrient bioavailability or quality. Therefore, adjustments should be made based on practical experience and current knowledge.

Balancing Protein and Amino Acids in Poultry Diets

Precision nutrition strategies aim to improve feed efficiency, reduce feed costs, enhance animal health and welfare, and minimize environmental impact. Precision nutrition strategies involve adjusting nutrient levels based on bird age, sex, breed, and environment, using feed additives or supplements for improved nutrient utilization, using alternative feed ingredients to reduce reliance on human-edible grains and legumes, and using feed restriction or phase-feeding to control body weight and fat deposition.

Protein is one of the most important and expensive nutrients in poultry diets. It provides the major building blocks for muscle growth, feather development, egg production, and immune function. Protein quality is determined by the amount and balance of essential amino acids (EAA) that cannot be synthesized by the bird and must be supplied by the diet. The most limiting EAA for poultry are lysine, methionine, threonine, tryptophan, and valine.

Balancing protein and amino acids in poultry diets means providing adequate levels of EAA to meet the bird’s needs without excess or deficiency. Excess protein or amino acids can increase feed costs, reduce feed intake, impair nutrient utilization, and increase nitrogen excretion. A deficiency of protein and amino acids can reduce growth rate, feed efficiency, egg production, egg quality, carcass quality, feathering, and disease resistance.

Optimizing Energy Sources for Poultry Nutrition

Energy is the most important nutrient in poultry diets because it determines feed intake and influences the utilization of other nutrients. Energy sources for poultry include carbohydrates (starches and sugars), fats (oils and animal fats), and proteins (amino acids). Carbohydrates are the main energy source for poultry because they are abundant, cheap, and easily digested. Fats are more considered concentrated sources of energy than carbohydrates and can improve feed efficiency, palatability, and energy density of diets.

However, fats can also increase the risk of rancidity, lower vitamin stability, reduce pellet quality, and affect the fatty acid composition of eggs and meat. Proteins can also provide energy for poultry, but they are more expensive than carbohydrates and fats and less efficient than fats. Therefore, proteins should be used primarily to meet amino acid requirements rather than energy needs.

Essential Vitamins and Minerals for Poultry Health

Vitamins, minerals are essential for the health and well-being of poultry. There are 13 vitamins, 15 minerals that are necessary for normal metabolism, growth, reproduction, and overall health. These include vitamins A, D3, E, K3, B1, B2, B6, B12, niacin, pantothenic acid, folic acid, biotin, and choline, as well as minerals such as calcium, phosphorus, magnesium, sodium, potassium, chloride, iron, zinc, copper, manganese.

Incorporating Fiber and Roughage in Poultry Diets

Fiber and roughage, a type of plant material, can have positive and negative effects on poultry nutrition. Fiber, mainly cellulose, hemicellulose, lignin, and pectin, can increase feed bulk, stimulate gut motility, enhance gut health, modulate blood glucose and cholesterol levels, and reduce disease risk. However, they can also reduce feed intake, lower energy and nutrient density, increase feed costs and waste production, and impair product quality. Therefore, they should be used with caution and moderation in poultry diets, and their effects should be closely monitored.

Utilizing Feed Additives for Poultry Gut Health

Feed additives, such as antibiotics, probiotics, prebiotics, enzymes, organic acids, essential oils, herbs, spices, antioxidants, and immunomodulators, are added to poultry diets to improve feed quality, animal performance, health, and welfare. They can affect poultry gut health by inhibiting pathogenic bacteria, promoting beneficial bacteria, enhancing digestion, modifying intestinal pH and microflora, balancing immunity, and reducing inflammation. However, their efficacy, safety, and legality may vary depending on the type, dose, source, quality, and regulation.

Managing Calcium and Phosphorus Levels in Poultry Feeds

Calcium and phosphorus are essential for poultry health, particularly in bone formation, maintenance, and eggshell development in laying hens. A balanced balance of these minerals is crucial throughout the bird’s lifecycle, considering factors like age, sex, breed, and production stage. Insufficient calcium can lead to poor bone quality, rachitis, and osteoporosis, while over-supplementation may cause cage layer fatigue and kidney damage.

Phosphorus is essential for energy metabolism, nucleic acid synthesis, and acid-base balance. Imbalances can result in osteomalacia, reduced egg production, and environmental pollution. Common sources of calcium and phosphorus include limestone, dicalcium phosphate, monocalcium phosphate, defluorinated phosphate, bone meal, fish meal, and phytase, an enzyme that enhances phosphorus release from plant sources.

Imbalances can lead to health complications and optimize production outcomes. Phytase’s role in sustainable nutrition is to unlock phosphorus from plant sources, reducing reliance on inorganic supplements and enhancing nutrient utilization while minimizing phosphorus excretion.

Strategies for Enhancing Digestibility in Poultry Nutrition

One of the key aspects of poultry nutrition is enhancing the digestibility of feed ingredients, which can improve nutrient utilization, performance, and gut health and reduce environmental impact. The ability of a feed ingredient or diet for poultry to digest and absorb nutrients is known as digestibility. Many factors, such as the source, type, form, and level of dietary fiber, the presence of anti-nutritional factors, the processing methods, and the interactions among feed components, can influence digestibility.

Dietary fiber is a major component of plant-based feed ingredients that can affect digestibility in poultry. Dietary fibers are classified into soluble and insoluble types, depending on their solubility in water. Soluble fiber, such as beta-glucans from barley and oats, can increase the viscosity of the digesta and reduce the activity and accessibility of digestive enzymes, resulting in lower digestibility of starch, protein, fat, and other nutrients.

Addressing Specific Nutritional Needs in Different Poultry Species

Precision feeding programs are designed to cater to the specific needs of broiler chickens raised for meat production. These programs aim to provide a balanced diet that includes energy, protein, amino acids, minerals, vitamins, and water to support their rapid growth and muscle development. The nutrient requirements of broilers vary based on factors such as age, sex, breed, health status, and environmental conditions.

One challenge in precision feeding programs is accurately estimating each bird’s nutrient intake and requirements. This can be achieved using sensors, scales, cameras, or other technologies that monitor feed intake, body weight, growth rate, feed conversion ratio, and health status.

Based on this information, feed formulation and delivery can be adjusted to provide the optimal amount and type of nutrients to each bird. Some systems use infrared sensors to measure body temperature and adjust feed energy content, while others use near-infrared spectroscopy to analyze nutrient composition and adjust feed ingredients.

Precision Feeding Programs for Broilers

Precision feeding programs for broilers can have benefits, such as improving feed efficiency, reducing feed costs, enhancing animal welfare, reducing nutrient excretion and environmental impact, and increasing meat quality and yield. However, precision feeding programs also have some challenges, such as requiring high initial investment, maintenance costs, technical skills, and data management.

Nutritional Considerations for Layer Hen Productivity

Layer hens are chickens that are raised for egg production. They have a lower growth rate and feed efficiency than broilers, but they have higher calcium and phosphorus requirements for eggshell formation. Layer hens need a balanced diet that provides enough energy, protein, amino acids, minerals, vitamins, and water to support their egg production and health.

The nutrient requirements of layer hens vary depending on their age, breed, egg size, egg production rate, health status, and environmental conditions. Therefore, precision feeding programs for layer hens aim to adjust the nutrient composition and quantity of feed according to the required needs of each flock or individual hen.

Minimizing Environmental Impact Through Precision Nutrition

Precision feeding programs for layer hens require accurate estimation of nutrient intake and requirements using sensors, scales, cameras, or other technologies. These systems monitor feed intake, body weight, egg production rate, egg quality, and health status, allowing for optimal feed formulation and delivery.

Benefits include improved feed efficiency, reduced costs, animal welfare, reduced nutrient excretion, and increased egg quality and yield. However, challenges include high initial investment, maintenance costs, technical skills, and data management.

Implementing Precision Nutrition in Organic Poultry Farming

Organic poultry farming, a system aiming to promote animal welfare, environmental sustainability, and human health, requires specific nutrition requirements such as using organic feed ingredients, providing access to pasture or outdoor areas, and avoiding synthetic additives or medications.

Implementing precision feeding programs in organic poultry farming involves finding organic feed ingredients that meet the nutrient requirements of poultry, which are often more expensive and less consistent than conventional ingredients. To ensure optimal nutrient intake, these programs need to select and formulate organic feed ingredients carefully.

Balancing feed intake and nutrient intake with access to pasture or outdoor areas is another challenge. These areas can provide additional nutrients but can also reduce feed intake due to lower palatability or increased energy expenditure for foraging or thermoregulation. Therefore, precision feeding programs must monitor and adjust feed intake and nutrient intake based on these factors.

Conclusion

Precision nutrition strategies for poultry farming improve efficiency and sustainability by accurately characterizing ingredients, determining nutrient requirements, and managing them carefully. This approach integrates modern technologies, reducing environmental impact and improving overall poultry welfare.
