Embodiment 1

[0014] Preparation: According to the literature "Preparation of nano-selenium by chitosan template method" (see: Wang Hongyan, Zhang Shengyi, Liu Mingzhu, Gao Hongwen, Tian Yupeng. Applied Chemistry. 2004, 21(8): 788-792.) Sugar is used as a soft template to prepare nano-selenium. In terms of weight percentage, the content of selenium is 0.5%.

[0015] Take 100 kilograms of montmorillonite, 2 kilograms of nano-selenium, and 3 kilograms of cysteamine and mix them well, then mix them with 500 kilograms of fructo-oligosaccharides and mix well to obtain a livestock and poultry meat quality improver.

[0016] The application test of the livestock and poultry meat quality improver on finishing pigs shows that adding 0.5-0.8% of the livestock and poultry meat quality improver in the diet significantly improves the carcass composition of the finishing pigs. The lean meat percentage increased by 3.6% (P<0.05), the fat percentage and back fat thickness were reduced by 18.5% (P<0.01) and 17....

Embodiment 2

[0018] Preparation: According to the literature "Preparation of Nano Selenium by Glucosan Template Method" (see: Wang Hongyan, Zhang Shengyi, Zhang Li, Cao Wengen, Wang Jianhua, Shi Hongwei, Zhuo Xin, Wang Cong. Journal of Anhui University (Natural Science Edition). 2005, 29( 1): The method of 81-85) uses glucosan as the soft template aqueous phase to prepare nano-selenium. In terms of weight percentage, the content of selenium is 0.1%.

[0019] Take 200 kilograms of montmorillonite, 50 kilograms of nano-selenium, and 12 kilograms of cysteamine, mix well, and then mix with 100 kilograms of fructo-oligosaccharides and mix well to obtain a livestock and poultry meat quality improver.

[0020] The application test of livestock and poultry meat quality improver on broiler chickens shows that adding 0.3-0.6% livestock and poultry meat quality improver in the diet can significantly improve the carcass composition of broiler chickens, the breast muscle rate has increased by 11.2% (P<0.01...

Embodiment 3

[0022]Preparation: According to the literature "Preparation of Nano Selenium by Sodium Carboxymethyl Cellulose Template Method" (see: Wang Hongyan, Zhang Shengyi, Gao Hongwen, Tian Yupeng. Functional Materials, 2004, 35(2): 259-261) Sodium is used as a template to prepare nano-selenium in the aqueous phase. The selenium content is 0.25% by weight percentage.

[0023] Take 150 kilograms of montmorillonite, 30 kilograms of nano-selenium, and 10 kilograms of L-carnitine and mix them well, then mix them with 310 kilograms of fructo-oligosaccharides and mix well to obtain a livestock and poultry meat quality improver.

[0024] The application test of livestock and poultry meat quality improver on meat ducks showed that adding 0.4-0.7% livestock and poultry meat quality improver in the diet increased the daily gain of meat duck by 6.8% (P<0.05) and the feed-to-weight ratio decreased by 7.2%. (P<0.05), the feathers of the test ducks are plump and shiny. The carcass composition of meat du...

Abstract

The farm meat quality improver consists of nanometer selenium 2-50 weight portions, cysteine 3-12 weight portions, fructose oligose 100-500 weight portions, and montmorillonite 100-200 weight portions; or consists of nanometer selenium 2-50 weight portions, L-carnitine 5-15 weight portions, fructose oligose 100-500 weight portions, and montmorillonite 100-200 weight portions. Montmorillonite has the effect of stabilizing nanometer selenium, cysteine and L-carnitine, controlling their release and eliminating their negative effect on digestive tract of farm animal. The synergistic effect of montmorillonite and fructose oligose can raise the digesting rate of protein in small intestine, lower the content of scatol in hypodermal fat and muscle and reduce the content of cholesterol in muscle.

Description

Technical field [0001] The invention relates to a livestock and poultry meat quality improver. Background technique [0002] Animal husbandry has always been an important pillar industry of my country's agriculture. Since the reform and opening up, with the guidance of the market economy and the popularization of breeding science and technology, my country's animal husbandry production has developed rapidly and has achieved remarkable results. As livestock products are becoming more abundant, the market for livestock products is shifting from a seller’s market to a buyer’s market, and the market’s demand for livestock products has shifted from being mainly quantity to a consumption pattern that emphasizes both quantity and quality. Analyzing the current status of the quality of livestock products in our country, the outstanding problem is that the edible quality and safety of meat have decreased significantly. Consumers generally report that the color of the meat is light, the fl...
