Huigang Yellow Chicken's grain-feeding, seed-retention and management techniques. China's local chicken breeds are widely distributed and abundant in resources. They are constantly developed and used on the basis of the original chicken breeds, and are cultivated into broiler breeds with more superior production performance. This is also the current trend of chicken rearing. It is also a meat-type chicken breed that has been widely promoted in southern China in recent years. The artificially-selected Huigang yellow chicken has many advantages such as rapid growth, strong breeding ability, and good egg production performance, and has been well received by farmers. Where is it suitable for breeding? How to carry out artificial breeding?
The Huigang yellow chicken is suitable for feeding in a wide area and is suitable for breeding in Hunan, Hubei, Jiangxi, Sichuan, Chongqing, Guangdong, etc. The habit of seasoning is to be established in the yellow chicken rearing farm, and the appropriate ambient temperature is also controlled. One of the methods is that if the ambient temperature is too high or too low, the feed will be wasted. Therefore, in winter, care should be taken to keep it warm and cold. The temperature should be kept above 10°C. In summer, it is necessary to pay attention to the heatstroke and reduce the temperature to below 28°C. At present, many places in the south have cultivated green grass for feeding. Green feed is rich in some trace elements. It has good palatability and has a good effect on chicken growth, egg production and maintaining health. The green forage grasses that are suitable for planting by the common people include hn-mc Youcai, hn-mc Youyou, and hn-mc Youyoubaiye. In the feeding process, one feed can not be used for too much one time to increase the waste of green feed. It is advisable to feed one time not more than 1/3 of the depth of the tank to prevent the big chicken from eating small troughs and the chickens from eating large troughs.
In the aspect of feed management, farmers generally limit the feeding on feeds. Limiting on feeds is a very important part of the breeding and management of broiler breeders. It directly affects the breeding performance of breeders, and it also saves feed. , a technical measure to reduce breeding chicken breeding costs. Limiting feeding should be based on factors such as age, weight, health status and season. Meat breeder chickens generally limit their feeding from the sixth week of age. The method: There is a daily limit method, a two-day stop feeding method and the next day feeding method. In order to save labor and feed evenly, the method of feeding every other day and the method of feeding for two days a week are used. Here, in addition to limiting the amount of feed, we must pay attention to the quality of feed, especially the energy and protein levels in the diet, must be formulated according to the feeding standards. After 20 weeks of age, it is changed to feed chickens. At this time, it is still necessary to limit the feeding. The main forest determines the feeding amount according to the laying rate and weight of the breeding chickens. Especially around the age of 30 weeks, egg production has risen sharply and the body weight has also increased. If the amount of feed is limited, the production performance will be greatly affected. If the feeding amount is low, the egg production rate and the quality of the egg will be affected. On the contrary, if the feeding is too much, although the egg weight increases, the pass rate is low, the egg production rate is increased slowly, the egg production peak is also low, and the fertilization rate is also affected. Impact, at the same time, due to the large body size of the chicken, will affect its lifetime production capacity, but also will increase the breeder's mortality rate. When reaching the peak of egg production, the weight of hens is generally between 2.8 and 3.0 kg, so as not to increase, so as to ensure the good production performance of the breeding chickens.
When the number of chickens to be selected stays at a certain level, the local chickens should be gradually eliminated from the rooster to the hens, and finally replaced by good breeders. In the process of achieving improved seedlings, attention should also be paid to the selection of breeding chickens. In particular, the selection and breeding of breeding roosters should be strengthened, and identification of improved varieties should be carried out. Gradually breeder chick breeding systems should be gradually established so that excellent and productive chickens can be sustained for a long time. keep it up.
The Huigang yellow chicken is relatively adaptable to the environment, so the health condition is relatively good, and the frequency of the disease is relatively small. However, with the continuous expansion of the Huigang yellow chicken, the breeding direction or variety has more and more requirements on the production performance. The high growth rate of chickens makes the other indicators have a certain impact on the resistance of the disease, especially if the concept of the breeder does not change in time, or it is believed that the disease resistance of the Huigang yellow chicken will continue to remain high. At the level, there will be many seemingly simple problems that cannot be ignored.
