Principles and Basis for Formula Design of Broiler Feed
Feed formula is generally based on the requirements of slaughter and processing products, while ensuring the production performance of broiler chickens and reducing feed costs. When determining the feed formula for broiler chickens, the following factors should be fully considered to ensure the profitability of the entire production chain. The supply and price situation of feed raw materials; Slaughter age and live weight; Meat yield and body mass; Consumer habits (such as skin color, length of chicken storage period, etc.); Should male and female chickens be raised together or separately.
& nbsp; The design of broiler feed formula should be based on three aspects of information. Firstly, the nutritional requirements of broiler chickens are used to determine the nutritional specifications of the diet; Secondly, it is important to understand the content and availability of these nutrients in feed materials, as they are provided by various feed materials; Also, the current market price of the selected feed raw materials. With these three aspects of information, low-cost diets can be calculated through formula software. At present, there are many software available for feed formula calculation, and the main design principles are goal programming or linear programming. The operation process is to ensure that the set nutritional upper and lower limits are met while obtaining low product costs.
& nbsp; Low cost diets do not always bring significant profits, as the key lies in the specific differences in consumer demand for terminal broiler products. This requires accurate expectations of the future market value of broiler products when designing high profit diets. When formulating a feeding plan for broiler chickens, it is necessary to consider the composition of the body, especially during the late growth and fattening periods.
& nbsp; The energy requirement in the diet is greater than any other nutrient, so high-energy feed ingredients (grains, fats, etc.) account for a large proportion in broiler formula. Long term practice has proven that diets with higher energy concentrations can achieve better feed returns and economic benefits.
One of the promising developments in the field of poultry nutrition in recent years is to increase the utilization rate of some nutritionists by adding enzyme preparations to feed, including cellulase (cell wall) degrading enzymes, protein degrading enzymes, starch degrading enzymes, and phytase. The breeding of broiler chickens has made rapid progress, and there have been significant changes in their nutrition to better meet the nutritional needs of broiler chickens at various stages.
