Method for improving production performance of laying hens in high temperature phase in summer by nutrition regulation

Abstract

The invention relates to the field of poultry production, and specifically relates to a method for improving the production performance of laying hens in a high temperature phase in summer by nutrition regulation. The method comprises the following steps: separately adding 6-9g / kg of rosemary powder, 10-20g / kg of soybean oil, 200-300mg / kg of vitamin E and 100-200mg / kg of vitamin in a laying hen feeder in the high temperature phase or May to October every year. By virtue of the method provided by the invention, the quality and palatability of the feeder in the high temperature phase in summer can be improved, the thermal stress resistance of the organs is improved, the nutrition loss of the feeder in the storage process is reduced, and the production performance of the laying hens in the high temperature phase is improved by the regulation and control of four different nutritional factors.

Description

technical field [0001] The invention relates to the field of poultry production, in particular to a new mode for improving the production performance of laying hens in the summer high temperature period through nutritional regulation and control. Background technique [0002] The breeding quantity of laying hens in my country ranks first in the world, the breeding quantity of commercial laying hens is about 1.5 billion, and the egg production accounts for more than 40% of the world. Most of the provenances of laying hens currently raised are imported from abroad, and the feeding methods and dietary formulas have been relatively stable. However, during the high temperature period in summer, although modern chicken farms use wet curtains to cool down, the temperature in the house is still maintained above 30°C during the high temperature period in summer. Egg production, egg shell thinning, and egg quality decline. At present, increasing the egg production in high temperatur...

However, during the high temperature period in summer, although modern chicken farms use wet curtains to cool down, the temperature in the house is still maintained above 30°C during the high temperature period in summer. Egg production, egg shell thinning, egg quality decline

At present, increasing the egg production in high temperature season in summer is mainly through physical methods such as cooling the house temperature and spray cooling through wet curtains. There are also suggestions to add (animal or vegetable) oil, vitamins and other methods to the feed, but usually it is a separate study of different nutritional factors. There is a lack of literature reports on the simultaneous regulation and control of multiple nutritional factors to improve the laying performance of laying hens based on nutritional principles
