Pay attention to the daily management of backup hens

Feeding and management in the early stage of production

Group at the right time. Breeder cocks and hens should be grouped in time after strict selection at the age of about 18 weeks. In order to make the rooster adapt to the new environment and facilitate the establishment of the order grade of the group, the rooster was transferred to the laying house 4 ~ 5 days in advance according to the normal proportion of male and female. In order to prevent the breeding from being pecked by each other after grouping. Then transfer to the hen, and the group should be finished at the age of 20 weeks.

Increase the light during the growing period. In order to control the sexual maturity of breeder chickens, more measures should be taken to limit the light, but lighting stimulation should be carried out from about 18 weeks of age, so that the chickens can start production in time. The implementation of light enhancement stimulation should be consistent with the mature body weight, and if the body maturity of chickens is delayed or sexual maturity is advanced, the light stimulation should be delayed for 1 ~ 2 weeks, and if the sexual maturity and body maturity of chickens are ahead of schedule, light stimulation should be increased in advance.

Change the feed. After entering the pre-production period, the feed for breeding chickens should be replaced with feed for pre-production, and the feed for pre-production should be prepared according to the physiological characteristics of breeder chickens and the requirements of future production. Its nutritional level is much higher than that of breeding hens and close to that of laying hens (slightly lower calcium content), which can improve the nutritional status of breeder hens and increase the necessary nutritional reserves. Under the condition that the weight of the chicken is kept in the recommended range, gradually increase the feed quantity, and change the feed to five or two feed or daily feed every other day, but the food intake should still be controlled to prevent the weight from gaining too fast.

Male and female are fed separately in the same column. During the breeding period, there are some differences in nutritional requirements and feed intake between Roosters and hens, and the rate of weight gain is also different. After the rooster and hen are mixed, the feeding speed of the chicken is accelerated, and it is easy for the rooster to eat more feed than the hen, resulting in overweight and affecting the reproductive condition. Therefore, after 20 weeks of age, male and female should be fed separately in the same column. The method is that the hens are fed in the feed trough, which is equipped with a grid of 4.2 cm ~ 4.5 cm wide, so that the head of the rooster can not reach in, while the head of the hen can reach into the feeding; the rooster uses the material bucket and hangs the material bucket 41 cm ~ 46 cm, in order to prevent the hen from reaching for food, and the rooster can stand up and be able to feed.

Reasonable feeding during laying period

The broiler breeder chickens will lay eggs one after another from 24 weeks to 26 weeks old, that is, they will enter the egg-laying stage. During the laying period, the breeding hens should be fed reasonably according to the changes of egg laying rate and body weight, so as to produce as many qualified breeding eggs as possible. In the feeding method, it should be noted that when feeding, the feed in the trough should be evenly distributed, and the trough should be cleaned frequently, especially in the rainy season and summer, the wet or dirty old materials in the trough must be removed, and there should be no mildew in the trough, let alone mildew feed. Feed should not be too full in the trough, otherwise it will be scattered by chickens and feed will be wasted. Drinking water must be clean and fresh, drinking fountains or sinks should be cleaned every day, and nipple drinking fountains should often be checked one by one, otherwise chickens will not be able to drink water due to reasons such as lack of water from drinking fountains, which will affect egg laying and even cause chicken death. The amount of feed should be flexibly controlled according to the change of egg production.

An increase in the amount of feed during the rising period of egg production. The egg laying rising period of broiler breeder chickens refers to the period from the laying rate of 5% to the period before the egg production peak. With the gradual increase of egg laying rate and the continuous growth of body weight, the demand for nutrition is increasing continuously. Adjusting the feed supply of chickens according to the change of egg production rate is the main measure of raising work in this period. Generally, from 24 weeks old to 27 weeks old, the feed amount of breeder hens increases by 10 g ~ 11 g per week, and that of breeder cocks by 8 g ~ 9 g per week. The increase of feed yield is earlier than the increase of egg production rate. Under normal circumstances, it is appropriate to increase the amount of feed, and the laying rate will increase at a rate of 3% to 5% per day.

Daily management of laying period

Environmental control. To provide the most suitable laying environment for laying hens, we must first have a good henhouse. Henhouses must protect laying hens from daily temperature changes. Because the egg laying will be affected when the temperature deviates from the optimum temperature range, the optimum temperature in the laying stage is 15 ℃ ~ 20 ℃, so the temperature fluctuation in one day should be avoided. The ideal relative humidity in the henhouse is 60%-70%. Ventilation makes the air environment of the chicken house good, generally through the exhaust fan ventilation, in the hot season in the chicken house installed ventilation wet curtain cooling system, can increase egg production and reduce chicken mortality.

Observe the chickens. After turning on the lights in the chicken house in the early morning, observe the mental state and feces of the chickens. If sick and weak chickens and abnormal chickens are found, they should be quarantined or eliminated in time; after turning off the lights at night, listen to the abnormal sounds of respiratory diseases in chickens, such as snoring, coughing, etc., should be isolated and eliminated in time to prevent expansion and spread. Observe the change range of the temperature, often look at the temperature and make a good record in summer, but also check the ventilation and drinking water system and light, and find that the problem is solved in time; when feeding water, observe whether the feed tank is adapted to the feeding and drinking water of chickens; observe whether there are pecking chickens, if found to be picked out in time, use purple potion to wipe out the blood or eliminate it in time.

Keep production records. In order to manage the flock well, we must make the production record of the flock well, because the production record reflects the actual production dynamics and daily activities of the flock, through which we can know and guide the production in time.
