Premixed feed capable of increasing egg yield of laying hens in summer as well as use method of premixed feed

Abstract

The invention relates to premixed feed capable of increasing egg yield of laying hens in summer as well as a use method of the premixed feed. The composite premixed feed consists of the following components in parts by weight: 8 to 14 parts of composite vitamin, 30 to 40 parts of composite trace element, 90 to 130 parts of monocalcium phosphate and dicalcium phosphate, 250 to 300 parts of stone powder, 40 to 60 parts of table salt, 12 to 20 parts of choline, 50 to 100 parts of anti-stress functional pack, 20 to 25 parts of sodium sulfate, 25 to 35 parts of methionine, 20 to 30 parts of lysineof 70 percent, 3 to 6 parts of threonine, 5 to 8 parts of tryptophan, 10 to 20 parts of intestinal health regulator, 8 to 15 parts of composite enzyme preparation and 250 to 350 parts of kelp powder.A mode of balancing amino acid is adopted, low protein and high amino acid are adopted, plant fat is added to supplement energy, heat increment is reduced, and the anti-stress functional pack and theintestinal health additive are added, so that the heat stress resistance of the organisms can be significantly improved, and the production performance is continuous and stable in high-temperature season.

Description

technical field [0001] The invention relates to a compound premixed feed and its application method, in particular to a premixed feed and its application method for increasing egg production of laying hens in summer. Background technique [0002] Every year from May to October, the whole country is in a high temperature period. Although modern standard chicken houses have installed wet curtains or spray cooling facilities, the number of days in the house is above 30 degrees is still more than 60 days, and the chickens are in a state of severe heat stress. , feed intake decreases, egg production rate decreases, eggs are small and eggshell quality deteriorates, and in severe cases, chickens die. There are about 1.2 billion commercial laying hens in my country, and the loss of egg production caused by the high temperature in summer is huge. In addition to wet curtain ventilation, spraying and other equipment and facilities to reduce the ambient temperature in the house, improv...

Problems solved by technology

However, laying hens laying eggs is a physiological characteristic. Insufficient intake of nutrients will use up body reserves, resulting in a negative nutritional balance. This is why chickens are prone to large-scale disease outbreaks in autumn and winter.

[0004] Chinese patent "A method for improving the production performance of laying hens in summer high temperature period through nutritional regulation and control", application number: CN201710357827.1, publication number: CN107114315A, can improve the quality and palatability of feed during summer high temperature period, and enhance the body's heat resistance Stress ability, reduce the nutrient loss of feed during storage, and improve the laying performance of laying hens in the high temperature period through the regulation of 4 different nutritional factors. Without considering the amino acid balance factors and the influence of body heat increase consumption, body nutrition cannot be avoided Negative balance, and may have small eggs

The present invention can effectively reduce the tension of the central system function of laying hens, make them calm and peaceful, reduce the occurrence of crushing and suffocation, promote the digestion and absorption of nutrients, and enhance the disease resistance of laying hens. Cooling measures to reduce heat stress, without guaranteeing continuous production performance
