Abstract

The invention relates to a layer feed additive and a using method thereof. The additive is formed by mixing porcine gallbladder powder and carrot powder at a weight ratio of 1: (15-25). The using method of the additive comprises the following steps: adding the additive of which the mass is 2-5% that of the layer feed to the layer feed, mixing uniformly, and feeding the layers conventionally. By adding a small amount of additive to the basic layer feed, the vitamin A content in the egg can be obviously improved while the egg yolk color is maintained, and the cost of improving egg production with vitamin A is greatly reduced.

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...
