How to increase the fertilization rate of chicken eggs
First, do a good job selection of roosters When you go from breeding to egg-laying, you should choose to keep a healthy body, moderate body condition, long cheekbones, straight sternum, toes that do not bend, no physical defects, eyes that are gods, and sensitive, full crown and meaty red and full, The characteristics of males are clear, healthy and disease-free. Choosing to keep good breed roosters is a prerequisite for a high fertility rate. Second, the deployment of the gender ratio of chickens When the number of cocks is too low, individual hens do not get mated. 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 cocks that are usually suitable is: 10% for 25-30 weeks, 9.5% for 30-35 weeks, 9% for 35-45 weeks, and 8% for 45 weeks. Third, strictly control the condition of a good cock When the rooster is too fat, it is inconvenient to move and it is easy to get leg problems, affecting the cock's crawling and 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 understand and control the condition of the rooster: (1) Regularly check the fullness of the roosters' roosters to understand the actual condition of the roosters' roosters each week; (2) Periodically draw 5 to 10% of the roosters each weekend. Rooster, in order to know the actual weight gain of the rooster each week, to determine the amount of feed for the next week; (3) to feed the male and female separately so as 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. Fourth, weed out the weak cock, supplement the strong rooster Due to fighting, illness, or individual's poor competitiveness, there are always some cocks that become weaker each 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 of heatstroke cooling in the chicken house The cool climate favors the production of sperm, and the hot weather will reduce the quality and quantity of sperm. 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, chicken density should not be too large When the flock density is too high, some hens are less likely to be bred due to crowding, thus affecting the fertilization rate of the eggs. For a 1/3 floor, 2/3 shelf shed, the suitable density is 4-6 per square metre. Seven, strict scientific feeding and management The flock must be fed with high-quality and full-price compound feeds, and finding suppliers with stable quality and good reputation 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.
