Problems solved by technology

However, if the stimulation intensity is too large or the acting time is too long, the body will gradually lose its coping ability, show signs of exhaustion, and appear in a pathological state, which will cause the hypothalamus-pituitary-adrenal cortex axis to be out of balance, thereby reducing the secretion of cortisol. It is the common phenomenon of chronic heat stress in production that causes cortisol levels to drop

Embodiment

[0040] 24 7-month-old New Zealand male rabbits in good body condition and equivalent weight provided by Guangxi University Animal Husbandry Test Station were selected and divided into 4 groups with 6 repetitions in each group. The experimental male rabbits were kept in a heat stress environment of 31±2°C Medium feeding, the basal ration group was the control group, and the other 3 groups were the test groups. Adding vitamin E and vitamin C on the basis of the basal ration was called the test group 1, and adding vitamin E and saccharoterpene was called the test group 2. , add vitamin E, vitamin C and lipoic acid called test 3 groups.

[0041] The basal diet was prepared according to the recommended NRC (1977) maintenance requirement for adult rabbits. The formula and nutritional level of the basal diet are shown in Table 1. Test 1 group weight ton feed adds anti-heat stress additive component and weight is that vitamin E is 600g and vitamin C is 600g; Test 2 groups of weight to...

Abstract

The invention discloses an anti-heat stress feed additive for improving reproductive function of male rabbits. The anti-heat stress feed additive is added to a basal diet feed prepared for maintaining the right amount of recommended NRC (National Research Council) (1977) adult rabbits for uniformly mixing. The anti-heat stress feed additive added to a ton of feed comprises the following components by weight: 100 to 800g of lipoic acid, 100 to 600g of vitamin E, 100 to 600g of vitamin C and 0 to 600g of Saccharicterpenin. A result shows that the additive can obviously improve sperm viability and density and reduce abnormal rate (P<0.05), wherein anti-stress test 3 has the advantage of improving sperm viability; anti-stress test 2 has the advantage of improving sperm density; and all of the three additives can obviously improve the content (P<0.05) of testosterone in serum of heat stress bucks and do not have obvious difference (P>0.05) for improving the content of T3 and cortisol.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and relates to a nutritional and health-care feed additive, in particular to a heat-resistant stress-resisting agent with the functions of improving the immunity of male rabbits, protecting the reproductive system, maintaining libido, increasing the amount of ejaculation, and improving the quality of semen. Stimulating feed additives. Background technique [0002] Heat stress refers to the sum of non-specific physiological responses made by the body to any request made by the thermal environment when it is in a high temperature environment. Heat stress affects animals in many ways. First, heat stress affects animal feed intake and production performance; second, it leads to endocrine disorder; third, it reduces animal immunity, which in turn affects animal health. . Heat stress has a great impact on the reproductive potential of breeding animals, mainly in that it leads to the delay of p...
