Selenium-rich feed for laying hens

Abstract

The invention relates to the field of feeds for livestock and poultry, specifically to a selenium-rich feed for laying hens. The feed is prepared from the following raw materials by weight: 50 to 60 parts of barley husk, 45 to 55 parts of brown rice, 60 to 70 parts of a rice bran cake, 60 to 70 parts of whole rye flour, 180 to 200 parts of corn, 50 to 60 parts of barley shorts, 35 to 40 parts of soya bean straw, 2 to 3 parts of pork liver powder, 2 to 3 parts of dried sandworm powder, 2 to 3 parts of zeolite powder, 4 to 5 parts of watermelon seeds, 1 to 2 parts of river crab meat, 0.5 to 1 part of goose egg yolk, 2 to 3 parts of goose egg shell, 3 to 4 parts of fennel sprout, 4 to 5 parts of tender stem and leaf of Nymphoides peltatum, 2 to 3 parts of heartleaf houttuynia herb, a proper amount of salt and 4 to 5 parts of a feed attractant. According to the invention, selenium-rich raw materials like watermelon seeds, pork liver powder and goose egg yolk are added into the feed, so immunity and reproductive performance of laying hens are improved, the incidence rate of chicken flocks is effectively reduced, and the daily laying rate of laying hens is increased.

Description

technical field [0001] The invention relates to the field of livestock and poultry feed, in particular to a selenium-enriched laying hen feed and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for humans and poultry. It plays an important role in various physiological processes of the body. During the breeding process of laying hens, selenium is one of the essential trace elements in chicken feed. Selenium-containing feed not only It can ensure the normal growth and development of laying hens, and can also produce selenium-containing eggs to improve the food value of eggs. However, in the actual production of chickens, there are still many shortcomings in the application of selenium. Laying hens are deficient in selenium or use excessive selenium. The phenomenon of poisoning occurs from time to time, and only by rationally configuring the content of selenium in the feed can the normal growth of the chickens be guaranteed. ...
