Problems solved by technology

[0005] The invention provides a method for reducing the dark grain rate of eggs. By adding specific proportions of vitamins, prebiotics and amino acids to the feed of laying hens, on the basis of improving the internal nutrition of eggs, the dark grain rate of eggshells has been significantly improved. It can better improve the quality of eggshells, avoid unsalable and waste of eggs caused by the shape of eggshells, increase the commercial value of eggs, and solve the problems existing in the prior art

Abstract

The invention relates to a method for reducing the dark vein rate of eggs. The method comprises the following steps: respectively adding the following additive ingredients into daily ration feed of layers in percentage by weight: 0.01-0.015 percent of vitamins, 0.5-1 percent of probiotics and 0.05-0.1 percent of amino acid; and uniformly stirring. According to the method, a specific content of compound vitamins, compound probiotics and compound amino acids into layer feed, the dark vein rate of eggs can be remarkably improved, the commercial value of eggs and benefit of farmers can be increased while the egg quality is promoted.

Description

technical field [0001] The invention relates to a method for reducing the dark grain rate of eggs. Background technique [0002] Egg quality involves egg nutrition and eggshell quality. Declining eggshell quality will undoubtedly bring greater economic losses to farmers, and the quality of eggshells is not high, which also has a significant impact on the shelf life of eggs and the maintenance of nutrients. In view of the fact that there are many factors affecting eggshell quality, it is generally necessary to start with the cognition of eggshell quality evaluation factors. The eggshell quality evaluation factors of eggs mainly include eggshell strength, eggshell thickness, eggshell color brightness, and eggshell color uniformity. Whether there are dark spots, dark lines, gravel or abnormal wrinkle on the eggshell, etc. On the basis of the gradual improvement of laying hen breeding management, nutrient supply and environmental control, the eggshell quality of eggs is more af...
