Embodiment 1

[0024] The premix is ​​made of the following raw materials: 10kg lysine, 10kg methionine, 2kg threonine, 0.3kg phytase with an enzyme activity of 5000U / g, and the number of colonies is 2×10 10 0.25kg of cfu / g Bacillus subtilis, 0.6kg of xylanase with an enzyme activity of 10000U / g, and 76.85kg of secondary powder.

[0025] Preparation method: just mix the raw materials of the above weight evenly to obtain the premix.

[0026] How to use: Add this premix to the conventional feed at a ratio of 2% by weight, and mix evenly; conventional feeding is enough.

Embodiment 2

[0028] The premix is ​​made of the following raw materials: 5kg lysine, 6kg methionine, 5kg threonine, 0.5kg phytase with an enzyme activity of 5000U / g, and the number of colonies is 2×10 10 0.5kg of cfu / g Bacillus subtilis, 0.5kg of xylanase with an enzyme activity of 10000U / g, and 82.5kg of secondary powder.

[0029] The preparation method and usage method are the same as in Example 1.

Embodiment 3

[0031] The premix is ​​made of the following raw materials: 17.5kg lysine, 2.5kg methionine, 1kg threonine, 0.4kg phytase with an enzyme activity of 5000U / g, and the number of colonies is 2×10 10 0.75kg of cfu / g Bacillus subtilis, 1kg of xylanase with an enzyme activity of 10000U / g, and 76.85kg of secondary powder.

[0032] The preparation method and usage method are the same as in Example 1.

Abstract

The invention discloses a premix for laying ducks. The premix comprises the following components: 5-17.5 percent by weight of lysine, 2.5-10 percent by weight of methionine, 1-5 percent by weight of threonine, phytase with the enzyme activity of 15-25U in each gram of the premix, xylanase with the enzyme activity of 50-100U in each gram of the premix, bacillus subtilis with the bacterial colony forming number of 0.5*10<8>cfu-1.5*10<8>cfu in each gram of the premix, and the balance of carriers. The formula of the premix is designed by a low-protein amino acid balancing technology and a proper amount of the phytase, the xylanase and the bacillus subtilis are simultaneously added, the nitrogen and phosphorus utilization rate is improved, the nitrogen and phosphorus emission is reduced, and the pollution of the premix to the surrounding water areas of a culturing farm is obviously reduced. By feeding the laying ducks with feed added with the premix, the nitrogen and phosphorus utilization rate of the laying ducks is improved and the nitrogen and phosphorus emission of the laying ducks is reduced under the condition of guaranteeing the healthy and normal production of the layering ducks, wherein the nitrogen emission is reduced by 30-35 percent, the phosphorus emission is reduced by 25-35 percent; and the invention has obvious economical and environmental benefits.

Description

technical field [0001] The invention relates to a compound premixed feed, in particular to a premixed feed for laying ducks. Background technique [0002] my country is the largest country in the world for laying duck breeding. There are more than 400 million laying ducks in stock, accounting for more than 70% of the total laying duck breeding in the world. The traditional water grazing and semi-grazing breeding methods for laying ducks. Generally, conventional premixes are only composed of vitamins, trace elements and some limited amino acids. These components can only fully meet the necessary nutritional needs for the growth and production of laying ducks. However, due to the anti-nutritional factors and animal Due to the digestive ability of the body itself, the nitrogen, phosphorus and other nutrients in the feed cannot be fully digested and absorbed (the general digestibility is 60-80%). environmental pollution. According to calculations, the amount of nitrogen and ph...
