Method for cultivating hens laying selenium-enriched eggs

Abstract

The invention discloses a method for cultivating hens laying selenium-enriched eggs. High-selenium active feed is fed to hens from a brooding period, the henhouse temperature and appropriate stocking are controlled, the feeding amount of the high-selenium active feed is gradually increased during an egg laying peak period of the hens, and the hens are fed in a mode of combining grazing and feed supplementing in a fence. Compared with the prior art, the content of selenium in eggs produced by the hens fed according to the method is 10-15 times that of selenium in ordinary eggs in the prior art. The selenium-enriched eggs laid by the hens fed according to the feeding method can supplement enough selenium while supplementing protein, and the immunocompetence and reproductive performance of the hens can be improved; and by combination with other nutritional ingredients in the feed, medicines containing the selenium element in the prior art can be replaced. Moreover, the selenium-enriched eggs have no side effect on the body and are low in cost and suitable for being eaten for a long term, the selenium supplementing effect is ideal, and the effect of homology of medicines and foods is achieved genuinely.

Description

technical field [0001] The invention relates to the technical field of laying hens, in particular to a method for raising selenium-enriched eggs.

Problems solved by technology

Zinc deficiency is present in most children and most pregnant women, and zinc deficiency can easily cause problems such as low immunity, loss of appetite, vision loss, and skin damage. The common zinc supplement method in the prior art is to eat some Medicines or health care products with zinc element, but medicines and health care products generally have certain side effects on the body, and are expensive, not suitable for long-term use, and the effect of zinc supplementation is not very satisfactory. How can we provide a zinc-enriched egg so that People can supplement enough zinc in the body while eating eggs, and the raising method of laying hens that produce zinc-rich eggs has become an urgent demand in the chicken industry
