Use of laying hen nutrition control technique in feed

Abstract

The invention relates to a feed formula for laying hens during the egg laying period and a preparation method thereof. The ingredients of the formula are corn, soybean meal, cottonseed meal, DDGS, phytase, helmus, compound vitamin and compound trace element, etc. The proportion of the ingredients is as follows: 35 percent to 55 percent of corn, 6 percent to 12 percent of soybean meal, 2 percent to 15 percent of cottonseed meal, 10 percent to 30 percent of DDGS, 5 percent to 30 percent of rice bran, 5 percent to 15 percent of stone powder, 0.4 percent to 2.5 percent of calcium hydrogen, 0.01 percent to 0.1 percent of phytase, 0.01 percent to 0.1 percent of helmus, 0.2 percent to 0.5 percent of compound vitamin and 0.2 percent to 0.5 percent of compound trace element. In addition, 0.5 percent of micro-ecological preparation can be added for maintaining the healthy bodies of the laying hens during the egg laying period. The feed prepared by the invention is proved that the utilization rate of phytate phosphorus has additive effect (p is less than 0.05) by simultaneous adding the phytase and cellulose through feeding tests. The phytase and the cellulose can be simultaneously combined for action, thereby degrading anti-nutrients in cell wall structures and promoting the release of nutrients. The laying hens have good egg laying rate, the body health status is improved, compared with the traditional feed for feeding, the egg laying rate is improved by 1.5 to 2.0 percent, and the production efficiency of the laying hens is greatly improved.

Description

Technical field: [0001] The invention relates to a feed formula for laying hens, in particular to a feed formula and a preparation method for laying hens during laying period. Background technique [0002] Animal nutrition is developing at an unprecedented speed. The concept of nutrition and its research and application scope have been extended from traditional nutrients to non-nutritional fields. It has been proved that the principle of action of non-nutritional technology in feed is mainly reflected by improving and regulating the metabolic process of substances and increasing their utilization efficiency. Therefore, non-nutritional substances that play this role can be more accurately called metabolism-regulating substances. Modern nutrition The concept of scientific integrity is the organic combination and coordination of nutrient substances and non-nutritional regulatory substances. [0003] There are well-established theories on the role of nutrients, and supporting t...
