A kind of premixed feed and its application method for increasing egg production of laying hens in summer

Abstract

The invention discloses a premixed feed for increasing egg production of laying hens in summer and a use method thereof. The premixed feed is composed of the following components in parts by weight: 8-14 parts of compound vitamins, 15-25 parts of compound trace elements 90-130 parts of monocalcium phosphate, 250-300 parts of stone powder, 40-60 parts of table salt, 12-20 parts of choline, 50-100 parts of anti-stress function package, 20-25 parts of sodium sulfate, 25-parts of methionine 35 parts, 20-30 parts of 70% lysine, 3-6 parts of threonine, 5-8 parts of tryptophan, 10-20 parts of intestinal health regulator, 8-15 parts of compound enzyme preparation, 250 parts of kelp powder ‑350 servings. The premixed feed of the present invention can not only improve the anti-stress ability of laying hens, increase the feed intake of nutrients, but also reduce heat consumption, increase the egg production of laying hens in summer, and at the same time effectively improve the quality of eggs. practical application value.

Description

technical field [0001] The invention belongs to the technical field of feed for laying hens, and particularly relates to a premixed feed for improving egg production of laying hens in summer and a method for using the same. Background technique [0002] From May to October every year, the whole country is in high temperature. Although modern standard chicken houses have installed wet curtains or spray cooling facilities, there are still more than 60 days when the house is above 30 degrees, and the chickens are in a state of severe heat stress. , the feed intake is reduced, the egg production rate is reduced, the eggs are small and the quality of the eggshell is deteriorated, and the chickens die in severe cases. The number of commercial laying hens in my country is about 1.2 billion, and the loss caused by the decline in egg production caused by the high temperature in summer is huge. In addition to wet curtain ventilation, spraying and other equipment and facilities to red...

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 the Summer High Temperature Period through Nutrition Regulation", Application Number: CN201710357827.1, Publication Number: CN107114315A, which can improve the quality and palatability of feed during the 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 egg undersize may occur

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
