Feed for enhancing comprehensive breeding performance of breeder cock

Abstract

The invention discloses a feed for enhancing a comprehensive breeding performance of egg-use breeder cocks. The feed includes 1% of a pre-mixed material which provides, for per kilogram of the feed, following nutrients including: 17500-18500 IU of vitamin A, 4800-5300 IU of vitamin D3, 195-215 IU of vitamin E, 9.1-10.5 mg of vitamin K, 9.5-10.5 mg of vitamin B1, 73-90 mg of riboflavin, 9.2-11 mg of vitamin B6, 0.12-0.23 mg of vitamin B12, 8.3-9.7 mg of folate, 392-412 mg of nicotinic acid, 86-95 mg of pantothenic acid, 6.4-7.8 g of choline, 0.47-0.56 g of calcium, 0.17-0.23 g of phosphorus, 0.07-0.15 g of copper element, 0.5-0.8g of iron element, 1.2-1.5 g of zinc element, 1.2-1.7 g of manganese element, and 9.2-10.6 mg of iodine. Per kilogram of the feed contains 0.34-0.45 mg of selenized chitosan. The feed can increase secretion of reproductive hormones, can improve the quality indexes of sperm, such as the amount of sperm, the activity and the viability of the sperm and the like, of the egg-use breeder cocks, and can enhance the breeding performance of the egg-use breeder cocks.

Description

technical field [0001] The invention relates to a feed, in particular to a feed for improving the reproductive performance of breeding roosters. Background technique [0002] In the poultry industry, due to the large number of breeding hens, especially after the artificial insemination technology is adopted, the breeding scale of breeding roosters is small compared to the breeding hens, so that the quality of them is ignored by people. However, body condition and performance of male breeders are critical to optimal chick production from each hen. When the semen quality of breeding roosters declines, the fertilization rate of breeding hens will inevitably decrease, which will directly affect the production efficiency of enterprises. [0003] With the development of chicken production in the direction of intensification and scale, the research link of breeding cock nutrition is still relatively weak, there is no special breeding poultry feed, and the production of enterprises...

AI Technical Summary

Problems solved by technology

[0003] With the development of chicken production in the direction of intensification and scale, the research link of breeding cock nutrition is still relatively weak, there is no special breeding poultry feed, and the production of enterprises generally feeds breeding roosters with hen feed, and the part of hen feed High content of nutrients, such as calcium, protein, etc., and high calcium and high protein will greatly inhibit the reproductive performance of roosters
