Special 1% premix for laying hens

Abstract

The invention discloses a special 1% premix for laying hens. The 1% premix comprises the following components in parts by weight: copper sulfate, ferrous sulfate, zinc sulfate, manganese sulfate, 1% potassium iodide, 1% sodium selenite, methionine, rutin, sulphuretin, tetrahydroxy stilbene glucoside, choline, palm oil, laying hens multivitamins, medical stone, rice bran, a mildew inhibitor and phytase. According to the growth requirement of the laying peak period, the invention develops a premix formula specially aiming at laying hens in the laying peak period through optimizing the types anddosage of vitamins and minerals in the premix, adding methionine, phytase and other components, and simultaneously adding the sulphuretin, rutin and tetrahydroxy stilbene glucoside, so that the premixhas scientific compatibility among components, has the functions of promoting ovulation, promoting digestion, adjusting organism metabolism function and supplementing nutrition, can effectively improve the resistance of the laying hens, improve the laying rate and average egg weight of the laying hens, reduce the feed-egg ratio and egg breaking rate, and has good social and economic benefits.

Description

technical field [0001] The invention relates to a 1% special premix for laying hens, which belongs to the technical field of animal feed. Background technique [0002] Premix is ​​the abbreviation of additive premixed feed, which is the combination of one or more trace components (including various trace mineral elements, various vitamins, synthetic amino acids, certain drugs and other additives) with diluent or carrier as required It is an intermediate compound feed product made after uniform mixing. Premix is ​​an important component of complete compound feed, and the commonly used premix additive ratio is 1%-5%. At present, in order to improve the growth rate and egg production efficiency of laying hens, most of the premix products on the market increase the content of amino acids, increase the content of antibiotics, or add traditional Chinese medicine premixes. However, increasing the amino acid content will cause the cost to increase and also cause unnecessary waste ...

AI Technical Summary

Problems solved by technology

However, increasing the amino acid content will not only increase the cost, but also cause unnecessary waste of protein raw materials

And the long-term use of a large amount of antibiotics in the premix not only increases the resistance of laying hens to antibiotics, but also causes direct or indirect harm to human health due to their residues in eggs

The pharmacology of most existing traditional Chinese medicine formulas is not clear, and it is difficult to effectively improve the egg production rate of laying hens

[0003] CN201710413843.8 discloses a formula of compound premixed feed product for laying hens accounting for 3% of the feed content. It uses methionine and lysine at the same time. Although the amino acid content is increased, the cost increases and it is easy to cause waste of protein

And the feed is aimed at the whole laying period of laying hens, and the nutritional requirements of laying hens are different at different stages in the raising process of laying hens, and it lacks specific design for different laying periods of laying hens
