1. Appropriately increase feed nutrient concentration
In the summer, when the ambient temperature exceeds 25 °C, the feed intake of the chicken will be correspondingly reduced, and the intake of nutrients will be correspondingly reduced, resulting in decreased egg production performance and poor egg quality. Diets with higher nutrient concentrations are compensated. In the hot season, the energy needs of the laying hens are reduced by 0.966 MJ per kg of feed metabolism compared to the usual feeding standard. Therefore, some experts believe that the energy concentration of feed should be appropriately reduced in summer; however, after laying hens, energy is the key to determine the egg production rate. At high temperatures, energy intake is often insufficient due to reduced feed intake, which affects egg production rate. Tests have shown that the egg production rate can be significantly increased after adding 1.5% cooked soybean oil to the feed during high temperature in summer. To this end, it is necessary to appropriately reduce the amount of cereal feed such as corn, so that it generally does not exceed 50% to 55%, and appropriately increase the nutrient concentration of the feed to ensure the normal performance of its production performance.
2. Increase the supply of protein feed as appropriate.
In the summer heat, the feed intake of chickens is reduced. Only by increasing the protein level in the feed as appropriate, and ensuring the balance of amino acids, it is possible to meet the protein needs of the laying hens. Otherwise, the egg production will be affected by insufficient protein. The protein content of the laying hens in the hot season should be increased by 1 to 2 percentage points compared with other seasons, reaching more than 18%. Therefore, it is necessary to increase the amount of the cake meal such as soybean meal and cotton kernel cake in the compound feed, and the dosage is not less than 20% to 25%. The amount of animal protein feed such as fish meal should be appropriately reduced to increase the palatability and increase the feed intake.
3. Careful use of feed additives
In order to avoid the stress reaction and egg production performance of laying hens caused by factors such as high temperature, it is necessary to add some anti-stress additives in feed or drinking water. For example, adding 0.1% to 0.4% of vitamin C and 0.2% to 0.3% of ammonium chloride in drinking water can significantly alleviate heat stress. According to the data report, adding 0.04% bacitracin to the diet can maintain the balance of the flora in the intestine, promote nutrient absorption, increase the feed conversion rate, and also have anti-stress effects. Adding 0.1% fumaric acid to feed or drinking water can effectively alleviate heat stress, increase feed intake and increase egg production rate. In a stress state such as high temperature and high humidity, 0.3% sodium bicarbonate is added to the feed (the method is first dissolved in clear water and then mixed, and fed after 10 to 15 minutes) to improve the heat resistance of the laying hen and The egg production rate has a significant effect, and at the same time it can greatly reduce the egg breakage rate. But be sure to pay attention to the amount of additives to prevent counterproductive.
4. Rational use of mineral feed
In the hot season, the phosphorus content in the diet should be increased appropriately (phosphorus can relieve heat stress), and the calcium content in the laying hen diet can be increased to 3.8% to 4%. Try to achieve calcium and phosphorus balance and keep The ratio of calcium to phosphorus is 4:1. However, too much calcium in the compound feed will affect the palatability. In order to increase the intake of calcium, it does not affect the palatability of the feed. In addition to increasing the amount of calcium in the feed, it can be supplemented separately to allow the chicken to eat ad libitum. Meet their physiological needs.
5. Pay attention to adding seasoning feed
In summer, the temperature is high, and the feed intake of the chicken is reduced. Adding certain seasoning feed to the feed can greatly improve the feed intake. Therefore, in order to improve the palatability of the feed and increase the appetite, the safe and effective flavoring agents such as sucrose, aminobenzoic acid and sodium glutamate should be selected to improve the feed intake under the premise of ensuring the quality of the feed.
6. Adjust the time to feed the feed
In production, the feeding frequency can be increased appropriately. In summer and evening, the temperature is lower. At this time, the feed intake of the laying hens is correspondingly larger. The feeding time can be adjusted. Each feeding is done before the lights are turned off in the morning and evening to ensure that the chickens are harvested. Eat enough feed.
