First, the selection of a good rooster should be selected from the rearing to the production of the egg-laying house. The body should be selected for physical fitness, moderate body condition, long cheekbones, straight sternum, toes not bent, no physical defects, dizzy eyes, and sensitive response. The crown and meat are bright and full-blooded, with obvious male characteristics, healthy and disease-free, and a kind of cock that meets the characteristics of breeds. Choosing to keep good breed roosters is a prerequisite for a high fertility rate.
Second, the rational sex ratio of the deployment of chickens When the number of cocks is too small, individual hens will not be able to obtain mating. When there are too many cocks, the following two unfavorable factors may occur: (1) the cock fighting each other intensifies, causing the cock to die; (2) the hen is chased by the cock or is over-mated, causing some hens to be afraid of cock and unwilling to accept Rooster mating. Therefore, the appropriate male to female ratio is a key to achieving a higher fertility rate in chickens. The percentage of cock that is usually suitable is: 10% for 25 to 30 weeks, 9.5% for 30 to 35 weeks, 9% for 35 to 45 weeks, and 8% for 45 weeks.
Third, strictly control the rooster's condition The cock is too fat, the action is inconvenient, and it is easy to get leg disease, affecting the cock's climbing across the mating. When the cock is too thin, the quality of the semen is poor, lack of vitality, and it is easy to be bullied and timid by other cocks and even hens. They are afraid or unable to mate.
A good cock should be moderate in condition, free of leg problems and full of vitality. Doing the following points will help you to understand and control the condition of the rooster: (1) Regularly check the fullness of the roosters' roosters to understand the actual condition of roosters per week; (2) Regularly draw 5% to 10% each weekend. The rooster, to understand the weekly actual weight gain of the rooster, according to which to determine the next week's feed; (3) the male and female feeding separately, in order to facilitate the control of the feed intake of the rooster, so as to effectively control the status of the rooster; (4) Take effective measures to prevent roosters from eating hens.
IV. Eliminating fragile cocks in a timely manner. Supplementing a strong cock Because of the fighting, disease, or individual's poor competitiveness, there are always some cocks that become weak after a certain period of time. Weak cocks not only have poor sperm quality, but often do not mate. The existence of weak cock can only play a role, can not increase the fertilization rate of eggs, and will mislead managers to estimate the gender ratio of male and female chickens. Another problem that is often not noticed is that when weak cocks reach a certain number of cocks and are still eliminated, due to the poor competitiveness of weak cocks, the amount of material that should have been eaten by weak cocks is The strong competitive cock is eaten, and if it goes on for a long time, it will cause the weight of some cocks to be difficult to control and exceed the standard. Therefore, we should eliminate the weak cock periodically and calculate the sex ratio of the male and female. When the ratio is too small, we must add the age-appropriate cock in time.
Fifth, do a good job in the heat of the chicken house in the summer cooling work cool climate conducive to the formation of sperm, hot weather will make the quality and quantity of sperm have declined. High temperatures also inhibit the performance of the flock and reduce the number of matings of breeders, which can lead to a decrease in fertilization rates.
The following measures may be taken to help achieve the purpose of cooling off during the summer: (1) ventilation in the house; (2) cooling of the wet curtain; (3) installation of spraying devices; (4) supply of sufficient refreshing drinking water to the flock; (5 ) Decrease the flocking density of chickens; (6) Feeding anti-heat stress additives.
Sixth, the density of the flock should not be too large When the flock density is too large, some hens are not easy to get mated due to crowding, thus affecting the fertilization rate of the eggs. For 1/3 ground, 2/3 shelving houses, the suitable density is 4-6 per square meter.
VII. Strict and scientific feeding and management The flocks must be fed with high-quality and full-price compound feeds, and finding stable and reputable manufacturers as feed suppliers is the key to guaranteeing the quality of feed. The cockerel must be separated from the bait because of the high concentration of calcium in the bait and the high-calcium diet also affects the cock's semen quality.
The management of litter and scaffolding is also very important, because the hard objects in the litter and the acute angle on the scaffold are one of the important factors that cause cocks to stumble.
