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.) method of natural polymer chitosan Sugar is used as soft template to prepare nano-selenium in aqueous phase. The content of selenium is 0.5% by weight.

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

[0016] The application test of the livestock and poultry meat quality improver on fattening pigs shows that adding 0.5-0.8% of the livestock and poultry meat quality improver to the diet can obviously improve the carcass composition of the fattening pigs. The lean meat rate increased by 3.6 percentage points (P<0.05), the fat rate and backfat thickness decreased by 18.5% (P<0.0...

Embodiment 2

[0018] Preparation: According to the literature "Preparation of Nano Selenium by Glucoside Glycan 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) prepares nano-selenium with glucosidan as the soft template aqueous phase. The content of selenium is 0.1% by weight.

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

[0020] The application test of the livestock and poultry meat quality improver on broilers showed that adding 0.3-0.6% of the livestock and poultry meat quality improver to the diet significantly improved the carcass composition of the broiler chicken, the breast muscle rate increased by 11.2% (P<0.01), and the abdominal fat...

Embodiment 3

[0022]Preparation: According to the method of "preparation of nano-selenium by carboxymethyl cellulose sodium template method" (see: Wang Hongyan, Zhang Shengyi, Gao Hongwen, Tian Yupeng. Functional Materials, 2004, 35(2): 259-261) with carboxymethyl cellulose Sodium was used as template to prepare nano-selenium in aqueous phase. The content of selenium is 0.25% by weight.

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

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

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 meat quality improver for livestock and poultry. 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 achieved remarkable results. Due to the increasing abundance of livestock products, 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 a quantity-based consumption pattern to a consumption pattern that emphasizes both quantity and quality. Analyzing the current situation of the quality of livestock products in my country, the prominent problem is that the edible quality and safety of meat have declined significantly. Consumers generally report that the meat is ...
