Changes in energy demand After warming temperatures in the spring, more energy feed will increase the weight of the chickens, which will not only promote chickens to lay eggs, but will reduce the chicken's egg production rate. The reduction in metabolic energy to 2700 kcal can significantly increase chicken production. The method of reducing the metabolizable energy content of chicken feed is mainly to reduce the proportion of corn and other cereals in chicken feed.
Changes in Protein Requirements When the chicken egg production rate reaches 50%, the protein content should reach 15.5%. After every 10% increase in the chicken egg production rate, the digestible protein content of the feed should be increased by 0.5%, but not more than 18.5%. The method is mainly to add more fishmeal, bean cake and so on.
Changes in mineral demand have increased with the rate of egg production, and hens’ demand for minerals has also increased. If there is a lack of calcium in the chicken feed, the chicken will have soft shell eggs, shellless eggs, and even eggs. Therefore, at this time, the calcium content in chicken feed should be increased from 2% to 3% to 4%, and the phosphorus content should be increased from 0.5% in winter to 0.6%. If the phenomenon of poor appetite in chickens is found at this time, the amount of salt in the chicken feed should be increased to 0.1%, and some mineral feed additives should be added appropriately.
Changes in Vitamin Demand As the egg production rate in spring chickens rises, vitamin supplements are needed.
