Problems solved by technology

However, since vitamin A is a fat-soluble vitamin, it has a storage function in the body. Overfeeding not only increases production costs, but also reduces egg production rate and fades egg yolk due to vitamin A poisoning.

Abstract

The invention relates to a feed additive for laying hens and a using method thereof. The additive is prepared by mixing pig gall powder and carrot powder in a weight ratio of 1:15-25. The method of using the additive is as follows: adding the additive with a mass of 2% to 5% of the feed for the laying hens to the feed of the laying hens, and after mixing evenly, the laying hens are fed conventionally. Adding a small amount of this additive to the basic layer feed can significantly increase the vitamin A content in the eggs produced while maintaining the yolk color, greatly reducing the production cost of vitamin A fortified eggs.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a feed additive for laying hens used to produce vitamin A-enhanced eggs and a use method thereof. Background technique [0002] Vitamin A is one of the essential micronutrients for the human body, and "vitamin A deficiency" is one of the four major worldwide nutritional problems confirmed by the World Health Organization (WHO). According to the survey results of WHO, about 140 million preschool children around the world suffer from vitamin A deficiency each year, and about 200,000 of the 80 million children under the age of 5 die each year due to vitamin A deficiency. The phenomenon of vitamin A deficiency among Chinese residents is also very common. In the conclusion of the fourth large-scale national nutrition and health survey released in 2010, it was pointed out that the average vitamin A intake of Chinese residents was only 59.8% of the recommended daily dietary inta...
