1. Create a suitable living environment for laying hens
In order to make laying hens produce more eggs, it is necessary to create a suitable growth and egg-laying environment for the chickens as much as possible, and to take corresponding supporting feeding and management measures according to the changing laws of different seasons. In the high temperature and high humidity season in summer, attention should be paid to preventing heatstroke and cooling, strengthening ventilation in the house, maintaining a dry environment, providing sufficient and clean drinking water to the chickens, and appropriately increasing the feeding amount of green vegetables to improve the feeding ability of chickens . In winter, special attention should be paid to the cold protection and heat preservation of the chicken house and artificial supplementary lighting. The temperature in the house should be maintained above 13 ℃, the light should be 15-16 hours, and the drinking water should be properly warmed, and ice water should not be drunk.
2. Pay attention to saving feed
The biggest expense of raising chickens is feed, which accounts for more than 70% of the total cost of raising chickens. Improper feeding and management will inevitably lead to a large amount of waste of feed. The measures to reduce feed waste are: First, the installation height, depth and length of the feed trough should be exchanged according to the different weeks of age and cage density of laying hens, and the amount of feed added should not exceed 1/3 of the depth of the trough. It is necessary to feed less frequently, reduce the leftover food in the tank, and determine the daily feed amount based on the egg production rate. Generally, when the egg production rate is 50%-60%, the daily feeding amount of each chicken is about 95-100 grams, and the egg production rate is about 95-100 grams. When the egg production rate is 60%-70%, the daily feeding amount is 105-110 grams, when the egg production rate is 70%, the daily feeding amount of the chicken is 115-120 grams, and when the egg production rate reaches more than 80%, the feed is not limited, let the chickens Eat ad libitum. The second is to cut the beak. Because chickens have the habit of slicing, therefore, chicks should be decapitated at 7-9 days of age. At around 15 weeks of age, beak trimming is required for those with poor beak trimming. Thirdly, promptly eliminate non-laying hens or chickens with poor egg-laying performance. At the end of breeding, when it is transferred to the laying house, a culling should be carried out. Those who are stunted, too small, too fat, sick, and lethargic should be eliminated. In the process of laying eggs, brooding chickens, sick chickens, disabled chickens, and discontinued chickens should be eliminated at any time. In the late stage of laying eggs, the chickens that are out of production are mainly eliminated, and hens with crests, pale faces, and shrinking crests should be eliminated immediately. Chickens that are found to be too fat or too thin should also be eliminated immediately. I think the lima feed machine will give you what you want.
3.The reasons for the decline in egg production
Environmental factors: changes in light program or light intensity: such as changing the color of light at any time, suddenly stopping light, shortening the light time, weakening the light intensity, irregular light time, long and short, early and late, suddenly light and suddenly stopped, evening Forgetting to turn off the lights etc. There is a serious lack of ventilation, and there is no ventilation for a long time. Attack of natural severe weather: A sudden attack by a heat wave, typhoon or cold snap without preparation or prevention in advance. Long-term water cutoff: The water supply system fails or forgot to turn on the switch, resulting in insufficient water supply or water cutoff for a long time.
Feed Factors: Significant changes in feed composition or quality issues in the diet can cause changes in egg production. For example, the types of raw materials in the diet suddenly change, the feed is not evenly stirred, the feed is moldy and deteriorated, the replacement of fish meal and yeast powder, the high salt content, the high amount of stone powder added, the replacement of cooked bean cakes with raw bean cakes, and forgetting to add salt in the feed, etc. Reduce the feed intake of chickens, causing indigestion. The egg production rate is normal, and the weight of the chicken does not decrease, indicating that the amount of feed and the nutritional standards provided meet the physiological needs of the chicken, and there is no need to change the feed formula.
Flock sickness: Acute and chronic infectious diseases can cause a sudden drop in egg production in a flock. If chickens are attacked by virulent Newcastle disease, egg production often decreases by more than 50%; infection with egg reduction syndrome can reduce egg production rate by 20% to 40%, such as mixed infection with other diseases, egg production rate decreases by 20% above. In addition, the infection of flocks with infectious bronchitis, infectious laryngotracheitis, cholera, coccidiosis, colibacillosis, avian influenza, etc. will greatly reduce the egg production rate.
4. Disease prevention work
Reducing dead chickens and preventing the occurrence of epidemics is the key to the success or failure of raising chickens. According to the scientific hygienic and epidemic prevention procedures for controlling the occurrence of chicken diseases, various vaccines should be injected according to the age of different chickens. At the same time, the chicken house and utensils should be regularly disinfected with drugs, and the feces in the house should be removed in time. mice, to prevent mice and sparrows from entering the house and bringing the epidemic. In order to reduce the chance of the spread of the epidemic, the entry and exit of people should be reduced as much as possible, strangers are not allowed to enter the chicken house, and visitors are refused to ensure the safe operation of the chicken farm.
