Design method for broiler feed formula

Abstract

The invention discloses a design method of a broiler feed formula, belonging to the feed industry. Carbohydrate, fat and protein in the feed are used as as the source of energy, but protein is not only the basic substance for forming somatic cells but also the raw material for forming various functional enzymes and hormones. Thus, only protein serves as the energy, which causes extreme waste. The purpose for the broiler to eat feed is mainly to satisfy necessary energy. If the energy is satisfied, the broiler stops eating. If energy in daily feed is insufficient, protein is decomposed to satisfy the requirement on energy, which wastes protein. If energy is too high, chicken eat few feeds, which causes insufficient protein and affects growth.

Technical field

[0001] The invention is a broiler feed formula design method, belonging to the feed industry. Background technique

[0002] Broiler feed formula design principle Energy and protein balance Broiler must have a certain basic energy for life activities. Energy comes from carbohydrates, fats and proteins in feed. However, protein is not only the basic material that constitutes somatic cells, but also the raw material for various functional enzymes and hormones. Therefore, only using protein as an energy source is a huge waste. Broilers take feed mainly to meet the necessary energy. When the energy is satisfied, eating stops. If there is insufficient energy in the diet, protein must be broken down to meet the energy needs, resulting in protein waste. However, when the energy is too high, the chicken intake will be reduced, which will cause insufficient protein and affect growth. Summary of the invention

[0004] In preparing diets, in addition to meeting the needs of calcium and phosphorus, it is also necessary to pay attention to the appropriate ratio of calcium and phosphorus according to the feeding standards. Because the absorption of phosphorus is closely related to the amount of calcium in the feed, if the ratio of calcium to phosphorus in the diet is not appropriate, or is in a combined state and is not easily dissolved, it will reduce the absorption and cause deficiency. Excessive calcium content is harmful to the growth of chicks, but also affects the absorption of phosphorus, magnesium, manganese, zinc and other elements. In general, the ratio of calcium to phosphorus is 1.1-1.5:1 for broilers and 5-6:1 for laying hens. The utilization rate of phytate phosphorus by chickens is low, about 30% for chicks and 50% for broilers; while inorganic phosphorus can be used 100%. Therefore, some inorganic phosphorus must be supplemented in the diet, and special attention should b...
