Problems solved by technology

In addition, in the later stage of laying eggs, the body’s ability to absorb, utilize and retain calcium in the feed decreases, resulting in a decrease in the amount of calcium used for eggshell formation, and the weight of the eggshell does not increase, resulting in deterioration of eggshell strength and eggshell thickness, and damage. Elevated rate

Abstract

The invention relates to a feed additive capable of improving egg shell quality in late laying period of laying hens. The feed additive capable of improving egg shell quality in late laying period oflaying hens is prepared by mixing the following ingredients in parts by weight: 5-8 parts of Rovimix Hy.d, 500-1000 parts of chelated zinc methionine hydroxyl analogue, 500-1000 parts of chelated manganese methionine hydroxyl analogue, 500-1000 parts of chelated copper methionine hydroxyl analogue, 20000-30000 parts of fine stone powder, and 50000-60000 parts of coarse stone powder. The feed additive disclosed by the invention is capable of improving strength and thickness of egg shell so as to reduce egg breakage rate.

Description

technical field [0001] The invention relates to a compound feed for laying hens in the late laying period, in particular to a feed additive for improving the eggshell quality of laying hens in the late laying period. Background technique [0002] Eggshell quality is one of the important indicators to measure the production performance of laying hens. Although the research on eggshell quality has continued for nearly 70 years, poor eggshells are still an important cause of economic losses in the laying hen industry; in the past 30 years, eggshell Although the quality has improved, the breakage rate of chickens raised by general professional households is still 2.0%-4.5%, and some are as high as 10.0%. The loss rate caused by breakage is between 6.0% and 10.0%. The economic loss caused to the poultry industry in the United States due to the quality of eggshells reaches more than 100 million US dollars, and the economic loss caused by this in my country reaches more than 500 m...
