Special composite additive premix for high-protein cottonseed meal for egg-laying duck

Abstract

The invention provides a special composite additive premix for a high-protein cottonseed meal for an egg-laying duck. The special composite additive premix comprises the following components in percentage by weight: 1.22 to 1.42% of complex vitamin, 3.8 to 5.2% of complex multi-ore, 32.5 to 52.3% of compound amino acid, 0.05 to 0.2% of compound enzyme, 3.2 to 5.6% of a microbial preparation, 0.05 to 0.2% of ethoxy quinoline, 1.2 to 2.8% of a phagostimulant, 1.32 to 2.55% of an immunopotentiator, and 24.85 to 53.66% of a vector. According to the special composite additive premix for the high-protein cottonseed meal for the egg-laying duck, an additive is adopted in view of the defect due to the quality of the high-protein dephenolized cottonseed meal, so that the dosage of the high-protein dephenolized cottonseed meal is greatly increased, and the product quality is not impacted while the cost of daily ration is greatly decreased. By adopting the special composite additive premix, the cottonseed meal resource can be fully utilized, and the imbalance between supply and demand of the raw feed protein can be alleviated.

Description

technical field [0001] The invention relates to a feed, in particular to a compound additive premix for egg-duck high-protein cotton meal. Background technique [0002] Animal husbandry is an important part of large-scale agriculture, and its status in the development of my country's national economy is increasingly strengthened. 60-80% of the total production cost of animal husbandry comes from feed, and the feed industry is an important link and foundation of animal husbandry. An important factor affecting the development speed and quality of my country's animal husbandry at present is the shortage of feed raw materials. The main raw materials of the feed industry are grain raw materials (accounting for 60%), protein raw materials (accounting for 30%) and additives, etc., especially the shortage of protein feed raw materials is the most important factor restricting the development of my country's feed industry now and in the future. At present, the protein raw materials ...

Problems solved by technology

[0003] The crude protein content of ordinary cotton meal is low (40%), the crude fiber is high (12%), and the content of gossypol is high (1400ppm). Due to the factors of the process, it is also mixed with a certain amount of cotton wool, which will affect the nutrition. The ingredients are digested and absorbed. At the same time, due to the existence of gossypol, it will also cause poisoning symptoms in animals, which will have a large degree of side effects on production.

Due to the improvement of the process, the crude protein of high-protein dephenolized cottonseed meal has increased, and the content of gossypol has also decreased, but the content of gossypol is still above 500ppm, and the content of phytate phosphorus is as high as 0.65%, which affects the content of other elements. Absorption, lysine, threonine and other essential amino acids are also relatively low. According to the barrel principle of amino acids, these will affect the digestion and absorption of other amino acids, thereby reducing the manifestation of their nutritional value

At the same time, due to the existence of non-starch polysaccharides in cotton meal, when such cotton meal is used in high doses, the utilization rate of laying duck feed will be greatly reduced, and the color and smell of egg yolk will also be affected.
