In the production process of laying hens, there is heavy protein and light energy, while the utilization of feed protein is neglected. Some chicken farmer feed formulations remain the same, and some add some trace ingredients. The following is a detailed discussion of the problems that exist in the material of laying hens and hopes to draw lessons from the chicken farmers.
First, the feed formulation immutable feed formula should be adjusted with different seasons, different feed intake of the flock, can not be fixed. When the intake is small, various nutrients in the feed should be increased. It can be seen from the following formula that the nutrient content in the feed varies with the feed intake. Formula: Feed intake Nutrient composition = fixed number (every chicken needs certain daily nutrition).
Second, attach importance to protein, light energy In the daily feed formulation, energy and protein are the two main elements of feed, are very important. In a sense, energy is more important than protein. Energy determines the rate of egg production in the flock and the protein determines the size of the egg. In the survival and production of chickens, energy plays a leading role. When the protein in the feed is high, while the protein is decomposed into energy, it also produces a large amount of uric acid, causing chicken gout, and at the same time increasing the feed cost, so the high-protein, low-energy feed is not a good feed. Keep energy and protein balanced; let energy and protein do their part.
Third, excessive addition of some trace components in the feed contains a variety of trace components such as vitamins, trace elements and so on. These ingredients are not as good as they are. Adding too much on the one hand will increase the cost, and on the other hand, it will affect the absorption of related nutrients. Therefore, the principles used for these substances are many, if not less, supplements. Fourth, ignoring the use of feed protein nutrition protein in feed, in fact, the composition of amino acids is not the same, the utilization is not the same, to formulate feed, you must consider the use of protein and amino acid composition is balanced, can not only consider Price, otherwise prone to protein deficiency, and even the appearance of eclosion and other phenomena.
