Abstract
The invention discloses a feed additive for laying hens and application of the feed additive for the laying hens. Through use of feed additive, the function of the laying hens is not damaged, the taste of chicken is not changed and adverse effect on the laying hens are not generated while high-selenium, high-zinc and high-iron eggs can be obtained. The feed additive for the laying hens comprises an additive I composed of sodium alginate, selenium-enriched yeast, selenomethionine and selenocysteine, and an additive II composed of milkvetch, kudzuvine root, gynostemma pentaphyllum, shrimp shell meal, ramie leaf powder and lotus leaf powder; after one month of a lying-in period of the laying hens, the additive I and the additive II are alternately added into a feed, so that the content of selenium in the eggs is maintained to be 0.35-1.65mg/kg; compared with common eggs, the eggs laid by the laying hens fed with the feed additive have the advantages that the content of cholesterol is reduced by more than 35%, the content of protein is increased by more than 25%, the content of the selenium, zinc, iron and calcium is greatly increased, functions of the laying hens are not damaged, the adverse effect on the laying hens is not generated, and the original taste of the chicken is also maintained.
Description
technical field [0001] The invention relates to the production of a feed for poultry, in particular to a feed additive for poultry and its application, in particular to a feed additive for laying hens and its application. Background technique [0002] Feed additives refer to the addition of a small or trace amount of nutritive or non-nutritive substances to feed in order to improve feed utilization, ensure or improve feed quality, meet the nutritional needs of animals, promote animal growth, and ensure the health of animals. In poultry farming, especially in laying hen breeding, the scale of decentralized laying hens is generally around 10,000 feathers, and the cost of feed and management is relatively high. In addition, the price of eggs and other agricultural products such as pork has been low in recent years. In addition, often due to the occurrence of avian influenza virus, the poultry are killed by mistake, which leads to the depression of the farmers, and many farmers ...
