Laying chickens consume more nutrients during the peak period of egg production. Farmers need to make additional supplements to chickens in a timely manner to ensure the nutritional needs of laying hens. Therefore, the following principles should be followed when adjusting feeding hens: 1, reduce energy feed. The temperature in spring rises gradually. If you continue to feed high-energy feed during wintering, the weight of laying hens will increase, which will affect the egg production rate. The scientific approach is to reduce the proportion of grain feeds such as corn in the diet. 2, increase protein levels. Hens consume more protein during the egg production period, and their consumption is related to the chicken's egg production rate. Therefore, the protein raw material in the feed should be increased according to the increase of chicken egg production rate. The method is to properly add high-quality fishmeal, bean cakes, etc. in the diet and try to minimize the amount of miscellaneous fish when the cost permits. 3, vitamin supplements. Especially for vitamin D, when there is a long-term lack of diet, the egg production of laying hens will decrease, the shells will become soft and thin, and the absorption of calcium will be seriously affected. When the number of eggs produced by the chicken increases, the vitamin consumption also increases. Therefore, some green feeds can be properly fed and the amount of multidimensional ingredients in the feed can be increased. 4, increase the mineral content. The calcium requirement of the hen when it is laid is increased. For example, calcium deficiency in the feed will affect the quality of the eggshell, thereby increasing the damage of the egg. Severe chickens will cause soft shell eggs and shellless eggs. Deficiency of phosphorus, like calcium deficiency, can also cause discomfort in laying hens, such as puppies, anal fistulas, and quail eggs. Therefore, once the layer chickens are found to have dyspepsia, loss of appetite, weight loss, etc., the cause should be identified and the content of mineral supplements in the diet should be increased accordingly.
