Breeding method for improving liver antioxidant function of winter young sheldrakes

Abstract

The invention belongs to the technical field of biology breeding, and particularly relates to a breeding method for improving a liver antioxidant function of winter young sheldrakes. The method comprises the specific steps that (1) young sheldrake fodder is used for feeding the young sheldrakes six times every day, and feeding amount at each time is same; (2) the sheldrakes are chased out of sheldrake sheds for outside breeding, on rain and snow days, the sheldrakes are bred in the sheds, and an anti-stress nutrient solution is used for feeding the young sheldrakes once before and after the outside breeding every day; (3) shading treatment is carried out on the young sheldrake sheds every day, blue light and green light are used for performing light treatment on the young sheldrake sheds every day, the temperature inside the young sheldrake sheds is controlled to be 23-25 DEG C at 7:30-18:00 every day, and the temperature inside the young sheldrake sheds is controlled to be 20-22 DEG Cat 18:01-7:29 every day; quick growth and development and improvement of young sheldrake organs of liver, kidney and the like are effectively accelerated, robust growth of skeletons is accelerated, oxidation resistance capacity of the liver and kidney is strengthened, and winter growth capacity and egg laying capacity of the young sheldrakes are improved.

Description

technical field [0001] The invention belongs to the technical field of biological breeding, in particular to a breeding method for improving the antioxidant function of the liver of ducklings in winter. Background technique [0002] In the cold winter season, especially in the southern region where low-cost greenhouse farming is adopted, laying ducks are easily affected by low-temperature cold air and cause stress. Continuous stress often causes a series of physiological and biochemical reactions such as the neuroendocrine and immune status of the body, resulting in Livestock and poultry organs are damaged or dysfunctional, resulting in growth retardation and a decrease in egg production rate; especially for young shelducks that have just hatched in winter, the cold stress is very obvious and has a serious adverse effect on their growth, even Cause disease and death, trace it to its cause because the organs such as liver and kidney of young shelduck duck are not fully develo...

[0002] In the cold winter season, especially in the southern region where low-cost greenhouse farming is adopted, laying ducks are easily affected by low-temperature cold air and cause stress. Continuous stress often causes a series of physiological and biochemical reactions such as the neuroendocrine and immune status of the body, resulting in Livestock and poultry organs are damaged or dysfunctional, resulting in growth retardation and a decrease in egg production rate; especially for young shelducks that have just hatched in winter, the cold stress is very obvious and has a serious adverse effect on their growth, even Cause disease and death, trace it to its cause because the organs such as liver and kidney of young shelduck duck are not fully developed, cause the liver antioxidant function to be low, and then cause the young shelduck duck brooding period to be long and the success rate of brooding is low; Therefore, be badly in need of inventing a kind of Breeding methods to improve the antioxidant function of young shelduck livers in winter to change the current problems in winter breeding of young shelducks
