In summer, the weather is hot and hot, which seriously affects the feeding and laying of laying hens. How to improve the laying rate of laying hens and the economic benefits of laying hens has become an important issue for laying hens in summer. In order to maintain high laying performance in laying hens in summer, the authors refer to the experience of layer chicken cages manufacturers, the following points should be noted.
1. Add energy feed
In the hot summer, the appetite of the laying hens is reduced and the feed intake is reduced. Experiments have shown that when the ambient temperature exceeds 25 °C, the flock will reduce its own caloric production by reducing the intake of energy feed, resulting in a corresponding decrease in the intake of other nutrients, resulting in decreased egg production performance. Feed a diet with a higher nutrient concentration. Due to the poor ability of the chicken to adjust the energy intake, the energy level in the compound feed can be appropriately increased in the summer, and 1% to 2% of the oil is added to the diet to replace the carbohydrate to supplement the energy, which helps to maintain the production of the chicken. Egg rate and egg weight. Pay attention to the amino acid balance, appropriately increase the content of digestible crude protein in the diet, and improve the utilization of amino acids.
2. Increase the number of feedings
Ensure the feed intake of the birds. The temperature in the morning and evening is relatively low. At this time, the appetite of the laying hen is higher, and the feed intake is correspondingly larger. The feeding time can be adjusted, and the feeding time is increased once in the morning and at night.
3. Add vitamin C
Vitamin preparations can increase the resistance of chickens to stress factors. Add 100 mg of vitamin C to the diet of the laying hen in the summer, or add 0.1% of the vitamin C to the drinking water. Not only can it increase the egg production rate of chickens, but it can also enhance the chicken’s own resistance to bacterial and viral diseases.
4. Stir in the appropriate amount of green and juicy feed
The green and succulent feed has good palatability and is rich in multi-vitamins, which can increase the feed intake of the hens and benefit from health and heatstroke prevention. According to reports, 50-60 grams of carrot silk per chicken per day in the laying hen diet can effectively increase the egg production rate.
5. Appropriate amount of electrolyte
Poultry body temperature regulation mainly maintains dynamic balance through two aspects of heat production and heat dissipation.
Because the chicken body is covered with feathers and no sweat glands, the body temperature is mainly adjusted by increasing the amount of breathing, increasing the amount of drinking water and excreting. Increasing the alveolar ventilation rate is necessary for respiratory cooling, but can lead to the loss of carbon dioxide, resulting in acid-base imbalance. Adding a certain amount of electrolyte in the diet of the laying hen or drinking water can maintain the blood acid-base balance on the one hand, and maintain the osmotic pressure of the body on the other hand, increase the amount of drinking water and excretion, and alleviate the harm of heat stress. The laying rate of laying hens and the reduction of mortality have a certain effect.
6. Reduce the density of breeding and strengthen ventilation
The chicken flock density should be based on the house temperature, humidity and type of house. In the hot summer, try to reduce the stocking density, strengthen the ventilation and ventilation, can effectively reduce the small ambient temperature inside the house, and can increase the heat dissipation of the chicken body. Conditional chicken farms should be equipped with exhaust devices such as fans or fans, and the axial ventilation of the axial fans is optimal. Good ventilation conditions can reduce the temperature of 3 to 8 °C, which is of great significance in the practice of chicken production.
The above is the poultry equipment manufacturer for the farmers, about the use of chicken cages to raise chickens in the hot season, reasonable feeding is a key factor in the success of chicken breeding, which is also the key knowledge of chicken breeding technology. Farmers must earnestly accumulate knowledge about raising chickens, so that chickens can be raised scientifically and efficiently to ensure the healthy breeding of chicken farms.
