Feed additive for production of low-cholesterol eggs

Abstract

The invention belongs to the field of animal feed specially applicable to specific animals, and particularly relates to a feed additive for production of low-cholesterol eggs. The feed additive for the production of low-cholesterol eggs comprises the following components: tea polyphenols and yeast cultures. The additive significantly reduces the cholesterol content of eggs produced by laying hens,significantly improves the antioxidant resistance of the laying hens, and does not affect the egg yield, and the eggs produced have no odor.

Description

technical field [0001] The invention belongs to the field of animal feed specially suitable for specific animals, and in particular relates to a low-cholesterol egg feed additive. Background technique [0002] Laying hens are chickens that are raised to lay eggs to supply eggs. Unlike broilers, the main purpose of raising laying hens is to improve the quality of eggs, maintain or increase egg production, not to improve the quality of chicken. Eggs are the main source of income for laying hen practitioners. The development of the laying hen industry is of great significance to ensure the sufficient supply of animal food for urban and rural residents in our country. [0003] Eggs are rich in nutrients and have a high rate of digestion and utilization of nutrients, making them a good food for modern humans. my country is a big producer of laying hens. Eggs are one of the important sources of protein for the people. At present, the per capita consumption of eggs is 320 eggs per...

Problems solved by technology

However, there are still some problems, such as adding additives such as copper and fish oil to the diet of laying hens, the reduction rate of cholesterol content in eggs is about 10%, but the cholesterol content in eggs is still high; while reducing the cholesterol content in eggs, Egg production is also reduced at the same time, and the eggs have a certain odor, which affects the taste of the eggs. The method is cumbersome and unfavorable for operation. The production cost is high, and the cost is increased, so it is difficult to achieve the desired effect.

Using a class of hydroxymethylglutaryl coenzyme A reductase (HMGR) inhibitors (statins) to reduce the cholesterol content in eggs in the diet of laying hens, although the effect is good, but the price is expensive, and most of them are used for human medicine, so it is not easy Realize industrialization
