Feeding combination for brooding layers before six-week old

Abstract

The invention provides a feeding combination for brooding layers before six-week old, which includes a feeding I for layers before two-week old and a feeding II for layers between three to six-week old, wherein the feeding I comprises corn, puffed grains, puffed soybean meal, puffed soybeans, fermented soybean meal, insect protein, one level steam fish meal, plant oil, monosaccharide or disaccharides, calcium hydrogen phosphate, limestone powder, baking soda, compound trace elements, amino acid, choline chloride, salt, anti-stress agent, multi-vitamin, compound enzyme preparation and phytase raw materials; and the feeding II comprises corn, soybean meal, fermented soybean meal, puffed soybeans, insect protein, one level steam fish meal, plant oil, monosaccharide or disaccharides, calcium hydrogen phosphate, limestone powder, baking soda, compound trace elements, amino acid, choline chloride, salt, anti-stress agent, multi-vitamin, compound enzyme preparation and phytase. Compared with the existing layer feeding, the phase combination feeding is more reasonable and scientific, and the immunity and the survive rate of layers are obviously improved and the morbidity is obviously decreased.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to a two-stage compound feed combination suitable for raising brooding layer hens (0-6 weeks old). Background technique [0002] In the "Chicken Feeding Standards" (NY / T33-2004) promulgated by the Ministry of Agriculture of my country, the age of 0-8 weeks is divided into the brooding stage of laying hens, and the nutritional needs of laying hens at the age of 0-8 weeks are recommended, based on a nutritional standard , prepare a compound feed, and feed the brooding hens before 8 weeks of age throughout the period. In production practice, the age of 0-6 weeks is listed as the stage of brooding hens, but the same nutrition is given during this period, and only one compound feed is prepared for feeding. However, the metabolism of the laying chicks is strong, and the growth and development are extremely rapid. The weight of the laying chicks increases by 2 times compared with the ...

AI Technical Summary

Problems solved by technology

However, the metabolism of the laying chicks is strong, and the growth and development are extremely rapid. The weight of the laying chicks increases by 2 times compared with the birth weight at the age of 2 weeks, and increases by 10 times at the age of 6 weeks; the immune system of the laying chicks is not perfect, and the disease resistance is poor. In the past, it mainly relied on the humoral immunity produced by B cells in the bursa of Fabricius, and T cells participated in the immune response after 40 days of age, and the immune organs matured after 70 days of age

There are occasional special feeds for brooding before 2 weeks of age on the market, but the nutritional level is not high, the effect on chicks is not satisfactory, and it cannot be well connected with the diet after 3 weeks of age

[0003] Because the structure and function of the digestive organs of the 2-week-old chicken are not fully developed, the immunity is low, the stress is great, and the relative growth rate is the fastest period in life, it is required to be given feed with high nutritional level and high digestibility; At the beginning, the secretion of digestive enzymes such as amylase and protease in the chicks increased rapidly, but if the compound feed was prepared according to the traditional one-stage nutritional standards before 8 weeks or 6 weeks of age, it would often fail to reach the level by 8 weeks or 6 weeks of age. Reaching standard weight, or underdeveloped tibia at standard weight, and low immune levels
