Precautions for daily feeding of laying hens in winter

1, stop the light every night, after the chickens calm down, quietly into the henhouse, listening to chickens with or without respiratory symptoms, such as coughs, husky calls, dry, wet rales, screams. If yes, they must be singled out immediately, one must be selected, no delay, and isolation therapy should be conducted to prevent outbreaks of infectious diseases.

2. Check chickens once a day. It is advisable to find that there is no material to eat, the crown is purple, black, eyes closed, necks, wings or tail drooping, Zhang Chuanchuan, eye and nose have a lot of secretions, eye swelling, meat swollen. Phenomenal chickens should be picked out in time and placed on the downstream of the sink for observation and treatment to prevent infection of other healthy chickens. No treatment value should be eliminated immediately.

3. If a disease is found, the abnormal condition in the flock should be observed daily, and the drug should be administered in time to control the spread. In this case, drugs such as furazolidone and streptomycin that affect egg production should be used with caution. When chickens suddenly die and there are a large number of chickens, necropsy must be performed immediately to analyze the causes and prevent epidemics.

4. Observe feces every morning. Normal feces are shaped, often seen in strips, with a white layer of urate on the surface. The milk-like excrement, segmental excrement, thin excrement, egg white excrement, blood faeces, flesh red excrement, and yellow and green white excrement are all abnormal feces.

5. When changing the feed, it should be carried out gradually. At this time, attention should be paid to changes in the feed intake and egg production of the flock. If the egg production drops more significantly, the feed nutrient concentration should be increased.

6. When new chickens are transferred from bred to laying hens, chickens with weaker, less stunted, and lower body weight should be placed in the south side of the chicken cage with higher horizontal temperature and brighter light, and their management should be strengthened. Restricted feeding chickens, at this time free to feed, additional 0.1% of trace elements in feed, 2% of high quality fish meal, add 2 to 3 grams of vitamin E per 50 kilograms of feed to promote sexual maturation and body maturation So that it will be opened as soon as possible until the desired egg production is achieved.

7. Newly hatched new chickens, due to sudden changes in the environment (flat raising cages), unadapted, unfamiliar with caged living conditions and cannot drink water, eat less, should be adjusted in time, especially the use of nipple drinking water The broiler house should be carefully observed, and the chickens should be used with a drinking fountain. The phenomena of hanging heads, card necks, wings, and legs should be promptly discovered and rescued in a timely manner so as to avoid accidental casualties.

8, should always observe the quality of eggs, there are no brown eggs, soft skin eggs, too small eggs, double yellow eggs; protein, egg yolk concentration, egg yolk color is normal. Find problems and increase or decrease relevant raw materials in time.

9. In the late stage of laying, as the flock is eliminated, the number is decreasing. At this time, the flock should be merged at night. The aggressive chickens and weak chickens restricted by strong chickens from accessing, drinking, and activities are found to adjust the chicken cages in a timely manner to avoid loss.

10. Pay attention to changes in house temperature, odor, operation of fans, and switch fans and doors in time.

11. For breeder chickens, in order to increase the fertilization rate and hatching rate in the later period, the amount of feed should be strictly controlled, the weight of eggs must be reduced, and the quality of egg shells should be improved.

12, most chickens open, double yellow eggs, large eggs gradually increase, this time should pay attention to prolapse of the anus, scrofula phenomenon, and promptly will pick out the anus chicken, there is a therapeutic value of surgical treatment. Separate the snoring chicken from the scrofula and treat the injured chicken. Large wounds were sutured, lightly rubbed with purple water, and kept in isolation. At the same time, for each of the injured chickens, 4 to 50,000 penicillin units were intramuscularly injected daily, and one oxytetracycline was administered daily to prevent infection.

13. Before the peak of egg production, it is weighed once every two weeks. Each time a random sampling method is adopted, the 1% of the number of chickens is called, and the maximum, minimum and average weights are calculated. Then the weight is compared with the standard weight, and the amount of feeding is adjusted accordingly. And adjust the feed formula. After the peak period, the original feeding amount should be maintained. When the egg production volume drops sharply, the feeding amount should be slowly reduced, and the feeding amount should not be reduced too early, because the egg production rate is reduced after the peak, but the egg weight is still increasing. .

14, after the peak of egg production, chickens with chicken cocks shrinking, chickens with difficult to turn over the anus are singled out and fed with trace elements and various vitamins. Generally, egg production can be resumed within 25 to 30 days. If no measures are taken, these chickens will resume egg production for at least 2 to 3 months.

15. Observe the feed intake of chickens at any time. Every day, count the feed consumption of each chicken, and find that the feed intake has decreased. Find out the reasons and solve them in time.

16. Pay attention to catching chickens that have ran out of cages at any time to prevent birds, rats, and other animals from entering the henhouses to cause fright, flocking, and spreading diseases.
