Feed additive for layer chicken for laying high-selenium nutrition eggs

Abstract

The invention discloses a feed additive for layer chicken for laying high-selenium nutrition eggs. The feed additive comprises, by weight, 15-28 parts of deodorization enveloping agents, 25-30 parts of dry squid meal, 12.5-15 parts of dry pig kidney powder, 17.5-19 parts of dry sea cucumber powder, 5-7 parts of dried small shrimp powder, 20-25 parts of red bean, 2.5-3 parts of wheat germ meal, 1-2 parts of garlic, 15-17 parts of arillus longan, 20-35 parts of glutinous distillers' grains, 8-20 parts of fish meal, 7-15 parts of paulownia leaves, 7-15 parts of sweet potato leaves, 3-5 parts of radix astragali, 1.5-1.8 parts of vitamin D preparations and 0.4-0.8 part of sodium selenite. The feed additive has the advantages that the feed additive is healthful and safe, and produced feed with the feed additive is reliable in quality and has good taste; the eggs contain abundant selenium elements, and accordingly selenium requirements of human bodies can be met.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed additive for laying hens producing high-selenium nutritious eggs. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, additives, whey powder, oil, meat and bone meal, grain, sweet sorghum and more than ten varieties of feed materials. [0003] With the continuous improvement of the scale and intensification of animal husbandry production, the density of livestock and poultry breeding is gradually increasing, and the odor generated by livestock and poultry and their waste is increasing, which not only affects the normal production and life of human beings, but also endangers livestock and poultry. health and reduce production performance.

Problems solved by technology

[0003] With the continuous improvement of the scale and intensification of animal husbandry production, the density of livestock and poultry breeding is gradually increasing, and the odor generated by livestock and poultry and their waste is increasing, which not only affects the normal production and life of human beings, but also endangers livestock and poultry. health, reducing production performance

Odor produced by feces in laying hens will increase the amount of harmful and toxic components such as methane, hydrogen sulfide, ammonia, and carbon dioxide in the air, resulting in a relative decrease in oxygen content in the air and an increase in turbidity. Reduce air quality, produce peculiar smell, hinder the health and survival of people and animals; seriously cause diseases of the respiratory system of humans and animals, and reduce the efficiency of laying hens and the quality of eggs
