Reduce the feeding density and ensure good ventilation in the house.
In the brooding stage, the breeding density should not be increased for the sake of one-sided pursuit of scale, especially in order to keep warm, and ventilation should not be paid attention to. As a result, chicks are prone to respiratory diseases and arthritis when growing in a polluted air environment, which seriously affects the growth and development of chickens.5~6week-old weight is not up to standard, while chicks5~6Week's body weight was positively correlated with lifetime egg production performance.
reasonable illumination scheme
10~20weeks of breeding chicken reproductive system is very sensitive to light intensity and light time, every year4Mid to late month9The brooding chickens in the first ten days of the month are in the time when the sunshine time is getting shorter before the opening, so they need to be treated before the opening, and9Mid-late of the month to the following year4In the first ten days of the month, when the sunshine time is gradually increasing before the opening of the brood, natural light can be used before the opening of the brood. It should be noted that when adding light, the method of gradually adding light should be adopted, adding light every week.0.5hours until the light arrives16By the end of the hour, do not add violence and reduce violence.
Adopt high quality feed
At present, the metabolic energy of most feeds is on the low side. Although the crude protein level is relatively not low, the proportion of miscellaneous meal is on the high side, the content of available protein is low, and the utilization rate of feed is low, which makes the nutrition of chickens less than that of chickens. Therefore, puffed feed that is easy to digest and absorb and rich in nutrition should be used in the chick stage, so that chicks can grow rapidly and develop well.5~6Week can reach the standard weight, breeding stage, from.18weeks, the reproductive system of the chicken develops rapidly, so it should start from16After the week, pay attention to the supply of protein feed with balanced nutrition, so that the ovaries of the little hens can develop smoothly and start production in due course.
Different feeding methods in different seasons
When raising chicks in autumn and winter, the climate is suitable and the feed intake of chickens is too large, so the reserve chickens are in8~17Weeks of age should be appropriately limited feeding, so that the body maturity of the breeding chicken, sexual maturity to achieve synchronization, improve the uniform rate.;In summer brooding, due to the hot weather, the feed intake of chickens is low and the nutrition is insufficient, the energy level of feed should be increased to meet the needs of chickens. In addition, during the peak laying period, chickens should use high-energy and high-protein feed in summer, which can be used if conditions permit. The external temperature is greater30℃when adding1%~2%On the one hand, it can meet the energy shortage caused by low feed intake in hot weather, on the other hand, it can reduce the dust in the feed and improve the palatability because the oil is easy to be absorbed. In addition, high temperature and high humidity weather in summer causes mildew in feed, the reproductive system development of chickens is disturbed and inhibited, and even leads to ovarian degeneration, thus causing hens to not lay eggs, so mildew remover should be added to the feed in summer.
Reduce stress factors
To create a safe, stable and quiet living environment for chickens, strictly prevent the interference of noise, strong light and other factors, may reduce the stress of vaccination.
In short, there are many factors that affect the laying rate of laying hens. We should take different measures according to different situations to ensure that the first laying hens have a higher laying peak and improve our economic benefits.
