Premixed feed for improving egg yield of laying hens in summer and using method thereof

Abstract

The invention discloses a premixed feed for improving egg yield of laying hens in summer and a using method thereof. The premixed feed consists of the following components in parts by weight: 8-14 parts of multivitamins, 15-25 parts of composite trace elements, 90-130 parts of monocalcium phosphate, 250-300 parts of stone powder, 40-60 parts of edible salt, 12-20 parts of choline, 50-100 parts ofanti-stress functional packs, 20-25 parts of sodium sulfate, 25-35 parts of methionine, 20-30 parts of 70% lysine, 3-6 parts of threonine, 5-8 parts of tryptophan, 10-20 parts of an intestinal healthregulator, 8-15 parts of a complex enzyme preparation, and 250-350 parts of kelp meal. The premixed feed disclosed by the invention not only can improve the anti-stress capability of bodies of layinghens and increase the nutrient intake, but also can reduce heat increment and increase the egg yield of laying hens in summer, and simultaneously can also effectively improve the egg quality, therebyhaving good value of actual application.

Description

technical field [0001] The invention belongs to the technical field of laying hen feed, and in particular relates to a premixed feed for improving egg production of laying hens in summer and a using method thereof. Background technique [0002] From May to October every year, the whole country is in high temperature. Although the modern standard chicken house has 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, the ability to ...

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
