Feed for large-type adult cock breeders

Abstract

The invention relates to a feed for feeding large-type adult cock breeders in adult stage. The feed for large-type adult cock breeders is free of fish meal. The ingredients in weight percentages of the feed are as follows: 1% to 6% of special premixed feed, 60% to 80% of corn, 15% to 20% of bean cake, 1% to 2% of calcium hydrogen phosphate, 0.3% to 0.5% of table salt, 10% to 15% of wheat, and 0.1% of methionine. Take the AA+ broiler breeder of parent generation as an example, after feeding on the feed, the peak fertilization rate of breeder egg in the chicken breeders is increased by 1.5%, and the fertilization rate of breeder egg in the full reproductive period is increased by 3%. Take the breeding farm capable of breeding 0.1 million heads of chicken breeders per year as an example, the yield of fertilized eggs is increased by 0.3 millions per year and the revenue reaches 0.45 million Yuan. Calculated on basis of breeding 30 million heads of chicken breeders per year throughout the country, the revenue reaches 0.45 billion RMB, with considerable economic benefits.

Description

technical field

[0001] The invention relates to a feed for chickens, in particular to a feed for feeding fast and large adult male roosters in adulthood. Background technique

[0002] In modern poultry farming, fast meat chickens grow faster and faster, their body size is getting bigger and bigger, their feed intake is getting more and more, and their feed conversion rate is getting higher and higher. The acceleration of the growth rate of broilers is determined by genetic breeding selection, nutritional level and ratio of feed. The rapid growth of broilers has also brought new problems to the breeding of broiler roosters: the adult roosters are large and fat, which has caused a significant decline in the insemination ability of the roosters. How to maintain a good body weight of adult breeding cocks and ensure that the breeding cocks have a good insemination ability has become a problem that must be solved. Contents of the invention
