Feeding Methodologies

[Olalekan Danso]

Phase feeding, a dietary strategy that involves modifying feed composition over time, is important because it optimizes nutrient intake to meet an animal’s specific needs at different stages of growth or production, leading to improved performance and reduced costs. By adjusting nutrient levels (like protein and energy) in the diet as the animal grows, phase feeding minimizes overfeeding of nutrients, reduces nutrient excretion, and promotes efficient resource use.

The nutrient needs of animals change as they grow and enter different productive stages (e.g., laying eggs). The intake of animals also increases as they grow. This combination of increasing intake and varying nutrient needs make necessary to adjust the nutrient density of the diet. Animals required amounts of nutrient on a daily basis, for example x grams of lysine per day, or x milligrams of copper per day, or x milligrams of biotin per day, or x kilocalories of metabolizable energy per day, etc. The nutrient needs of animals are usually highly correlated with the daily rate of lean tissue deposition (i.e., in growing animals) or other productive traits (e.g., lying eggs, reproduction, milk production, work, etc.). Once average the nutrient needs for a period of time are determined, we then make an estimation of the average daily feed intake for the same period of time to calculate the nutrient density of the diet. This constant change in nutrient needs and feed intake make necessary to adjust the density of the diets of animals and hence results in phase feeding programs. A feeding phase can be of any lengths of time. However, the longer the phase the most likely is that animals will be consuming excess or deficiency of nutrient at the beginning and end of a feeding phase, respectively. Thus, using more feeding phases usually results in more efficient growth performance. For poultry, most breeding companies published recommendations for feeding phases. The downside of phase feeding is the difficulty of managing feed inventory, orders, and manufacturing at the feed mill. In summary, the number of feeding phases that are better for animals should be determined based on an economic analysis that into account biological performance, feed cost, feed manufacturing capacity, feed transportation cost, feed inventory management costs (e.g., storage, logistics, etc.) and the length of the productive life of an animal.

Phase feeding programs are important for maximizing broiler productivity by managing their nutrient requirements. It takes advantage of changes in the nutrient requirements of broilers at various stages of growth

Phase feeding is a feeding strategy that divides an animal’s growth period into distinct phases, each with a slightly different diet tailored to its changing nutritional needs. This approach optimizes growth, reduces production costs, and improves feed efficiency by minimizing overfeeding and wasted nutrients.

Phase feeding systems play a vital role in poultry nutrition by tailoring feed composition to different growth and production stages
