The important influence of chicken feed on egg quality
(1) The effect of chicken feed on egg composition:
Eggs are mainly composed of protein, fat and water, in which protein contains 11.6% protein, fat 0.18%, water 86.6%; egg yolk contains protein 16.7%, fat 31.6%, moisture 49.0%; feed on eggs in protein, fat, water The composition has little effect, but it has a great influence on some trace components. The levels of riboflavin, pantothenic acid, niacin and vitamin B12 in vitamin A, vitamin D and B vitamins in feed are related to their content in eggs. Some trace elements (such as iron, copper, manganese, iodine, etc.) in the feed are high in content, and the relevant components in the eggs are also high.
(2) The effect of chicken feed on eggshell quality:
The quality of the eggshell directly affects the quality of the egg. The content and proportion of calcium and phosphorus in the feed and the content of vitamin D are closely related to the quality of the eggshell. Calcium is the main component of the eggshell. The lack of calcium in the feed causes the eggshell to become soft and weak. Therefore, it is necessary to supplement a sufficient amount of calcium, and phosphorus is closely related to the metabolism of calcium. If the phosphorus content is too high or too low, it will affect the metabolism of calcium and affect the quality of the eggshell. Therefore, the calcium and phosphorus content in the feed should be kept at a reasonable ratio. Vitamin D is also associated with calcium and phosphorus metabolism, and when vitamin D is deficient, it affects eggshell quality.
(3) The effect of feed on egg yolk color:
The color of normal egg yolk is golden or orange. However, due to the influence of pigment (mainly lutein) and lipid content in the feed, the color of the egg yolk will also change. When lutein is lacking in the feed, the yolk color becomes lighter. Because lutein is fat-soluble, its absorption and utilization are related to lipids, so lack of lipids can also cause the egg yolk to become lighter.
(4) The effect of chicken feed on the taste of eggs:
If the fish feed contains excessive fish meal, rapeseed cake, choline, etc., it tends to make the eggs smell bad and reduce the quality of the eggs. Because these kinds of feeds are decomposed into trimethylamine by the microorganisms in the digestive tract of the chicken, if the trimethylamine absorbed from the digestive tract cannot be completely excreted, some of them enter the egg yolk and produce odor.
