Laying hen premix and daily ration prepared from premix

Abstract

The invention discloses a laying hen premix and a daily ration prepared from the premix. The premix is prepared from the following components: compound trace elements, multi-vitamins, laying hen compound enzyme, fish meal, a salpingitis preventing agent, organic acid calcium, an anti-stress agent, complex probiotics, phytase, methionine, betaine, choline chloride, salt, mountain flour, calcium hydrophosphate, ethoxy quinoline, rice hull powder and zeolite powder; and the daily ration contains 5% of the laying hen premix, and is matched with corn, bean pulp, bran and mountain flour. The laying hen premix has the beneficial effects that enough calcium is stored in marrowbones of the laying hen; the laying hen is stable in calcium metabolism before and after sexual maturation; development of sexual organs is fast; the morbidity of salpingitis caused by laying is reduced to 2% or below; the laying stress is effectively relieved; the immunity of the organism is enhanced; the laying hen premix has a significant effect on maintenance of a peak laying period in future; the premix is especially applied to the laying hen; smooth transition of the laying period of the laying hen can be realized; and full play of the laying performance of the laying hen is ensured.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a premix for laying hens and a ration prepared from the premix. Background technique [0002] In the "Chicken Feeding Standards" (NY / T33-2004) promulgated by the Ministry of Agriculture of my country, the growing laying hens are divided into three stages: 0-8 weeks old, 9-18 weeks old, and 18 weeks old to the beginning of laying. The chickens are divided into two stages from the beginning of laying to the peak period of egg production (egg production rate > 85%) and the late period of egg production peak period (egg production rate < 85%). In the actual production of laying hens, laying hen breeding feed is fed from 7 or 9 weeks old to 16 weeks old; from 17 weeks to 20 weeks old, laying hen feed and rearing feed are mixed in a certain proportion. A transitional feeding regime where little or no special production feed is used during this period. At present, it is rare to see ...

AI Technical Summary

Problems solved by technology

③Laying hens are very sensitive to stress due to increased production intensity, heavy physiological burden, poor resistance

In the "Chicken Feeding Standards" (NY / T33~2004) promulgated by the Ministry of Agriculture of my country, taking the two main nutritional indicators of metabolizable energy and crude protein as an example, the metabolizable energy required to raise a full-price diet for laying hens is 2800kcal / kg, crude protein is 15.5%, the metabolizable energy and crude protein required for laying hens should be 2700kcal / kg and 16.5% for the full-price diet in the early laying period, and the metabolizable energy and crude protein required for laying hens should be 2750kcal respectively / kg and 17%, therefore, the laying hens are only fed the rearing period ration, or only the laying hens are fed the pre-laying ration, or are fed the transition day which is a mixture of the two rations in a certain proportion. grain, cannot meet the nutritional needs of laying hens
