Under normal circumstances, breeding males and breeding females are bred separately. Then, in order to maintain a high fertility rate, hatching rate, and high-quality commercial chicks, the age of males and females and the timing of breeding must be considered. And proportions. These problems are mainly in the aspect of breeding cocks.
The sexual characteristics and sexual maturity of Sanhuang chicken breeder rooster are generally earlier than those of breeder hens. However, the breeder rooster needs to produce a large amount of sperm during the breeding period and bears a heavy breeding task. Therefore, the physical constitution of a breeder rooster needs to be healthy, strong, and vigorous. It is fully mature before the start of breeding. General requirements, the age of the rooster should be greater than the breeder hen or the same age, if the breeder rooster is younger than the breeder hen, the breeder rooster should be fully mature and have good ability to breed.
One or two weeks before the breeding hens are born, the breeding cocks should be placed in breeding hens so that the breeding hens and breeding hens are familiar with each other and the mate is selected. At the same time, the cockerel in the same column also needs a certain amount of time to establish the order in the group, reducing fighting and affecting breeding. Hens need to produce fertilized eggs after more than 20 hours of cock mating, and usually reach the highest fertility rate approximately 3 days after the deployment.
The roosters can be used 20 to 80 times a day, ranging from 0.1 ml to 1 ml per ejaculate. The number of matings per rooster depends on many factors such as competition, number of hens, population level, temperature, and lighting. The breeding time is much more every morning. Rearranged and timid cocks mate less in the group. The fertilizing ability of a rooster can be maintained for more than 20 days after one mating, but the fertility rate usually falls rapidly after 4 to 5 days. If the hens change their roosters during the production of eggs, they are mainly fertilized by the sperm of the new rooster 3 days after the replacement of the new rooster.
The correct ratio of males to females helps maintain a high fertility rate. If the number of roosters is too large, it will cause the rooster to compete for breeding and fight, which in turn will reduce the breeding rate and increase the feed cost for breeding roosters. However, if the number of cocks is too small, it will reduce the breeding opportunities for some hens and reduce the fertility rate. It may also cause the cocks to be bred too frequently, consume too much, and prematurely age and affect the ability to bred later. The exact proportion of male and female chickens is related to the breeder type and size, and the denominator ratios of the various types of yellow chickens are as follows:
Local fine varieties 1:12 to 15;
High-quality three yellow chicken varieties around 1:10;
Fast large yellow chicken breeds 1:8-10.
The fertilization rate of the eggs, the body condition of the rooster, and the actual ratio of male and female chickens should be checked frequently during production. Chickens die and die almost every day. The number of males and females in each pen often changes, and it takes a while to check and adjust the proportion of males and females. For a sick, ill-tempered and unwell-behaved cockroach, the cock with an abscess on the bottom of the foot should be eliminated and replaced in time.
