We always believe that chickens are used to produce chicken and eggs for economic benefits. We can choose to raise chickens in chicken battery cages . In the production process of chickens, even if we are not producing eggs, we will not increase or decrease the weight of leisure. In order to maintain normal physiological functions, it is still necessary to continuously obtain various nutrients from the feed. This need for chicken is called maintaining nutritional needs.

Maintaining feeding is the minimum nutritional requirement for normal chicken life. Whether it is growing chickens, laying hens, or hens in the rest period, they must first meet maintenance needs. Because to ensure the normal production of chicken, we must first maintain a constant body temperature and maintain the normal function of the respiratory, digestive, circulatory, nervous and endocrine systems. Chickens need to carry out muscle activities of starting, lying, and walking, which consumes a considerable amount of energy.

Chickens need to maintain a variety of normal digestive and physiological responses in the cages of breeding equipment, such as maintenance of osmotic pressure, regulation of normal pH of body fluids, and maintenance of bone firmness, all of which require a certain amount of mineral elements and vitamins. In order to keep the cells and body tissues constantly updated, maintain the body shape, and the feathers continue to grow, etc., a certain amount of protein is needed to compensate. Otherwise, the chicken body will lose weight, lose weight, and deteriorate health. Therefore, it is impossible for a chicken to engage in any production activities while maintaining the nutritional level below the feeding level.

Regarding the nutrients consumed by chickens to maintain their rearing in poultry farming equipment for sale, the egg cage manufacturers believe that they cannot directly form chicken products, and there is no economic benefit. Therefore, in chicken raising, the greater the proportion of nutrients used to maintain consumption, the more products are produced. Less, the lower the feed reward. How to reduce the maintenance consumption of chickens and increase the proportion of production in production is crucial to the benefit of raising chickens. Shortening the growth cycle of broiler chickens, reducing unnecessary activities of chickens, and strengthening feeding management can all reduce the consumption of nutrients in chickens. Therefore, they are effective measures to improve the production level of chickens, improve feed conversion ratio and economic benefits.
