How to adjust chicken feed in summer
1. Appropriately increase feed nutrient concentration In summer, when the ambient temperature exceeds 25°C, the feed intake of chickens will be reduced accordingly, and the intake of nutrients will be reduced accordingly. This will result in decreased egg production performance and poor egg quality. This requires the use of Diets with higher nutrient concentrations are compensated. During the high temperature season, the energy requirement of laying hens needs to be reduced by 0.966 megajoules per kilogram of feed metabolism energy compared to the usual feeding standards. As a result, some experts believe that the energy concentration of feed should be appropriately reduced in summer; however, after laying hens, energy is the key to determining the egg production rate. High temperatures often result in insufficient energy intake due to reduced feed intake and affect egg production rates. Tests have shown that after adding 1.5% cooked soybean oil to feed during summer high temperatures, the egg production rate can be significantly increased. To this end, it is necessary to appropriately reduce the amount of cereal feeds such as corn, so that they generally do not exceed 50% to 55%, while appropriately increasing the nutrient concentration of feed to ensure the normal performance of its production performance. 2. Increase protein feed supply, as appropriate During the hot summer days, the feed intake of chickens is reduced. Only by increasing the protein levels in the diet as appropriate, and ensuring the balance of amino acids, it is possible to meet the protein requirements of the laying hens. Otherwise, the egg production will be affected due to insufficient protein. In the hot season, the protein content of laying hens should be increased by 1-2% compared with other seasons, reaching more than 18%. Therefore, it is necessary to increase the amount of feeds for cakes, such as soybean meal and cotton cakes in compound feeds, in amounts of not less than 20% to 25%. The amount of animal protein feed such as fishmeal should be appropriately reduced to increase palatability and increase feed intake. 3. Careful use of feed additives In order to avoid the stress reaction and laying performance of laying hens caused by high temperature and other factors, 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 relieve heat stress. According to data reports, the addition of 0.04% Bacillus Peptide in the diet can maintain the balance of intestinal flora, promote nutrient absorption, increase feed conversion, and also have anti-stress effects. Adding 0.1% fumaric acid to feed or drinking water can effectively relieve heat stress, increase chicken feed intake and increase egg production. Under stress conditions such as high temperature and high humidity, add 0.3% sodium bicarbonate to the feed (the method is to dissolve in water first and then mix, feed 10-15 minutes later) to improve the heat resistance of the layer and The egg production rate has a significant effect, but at the same time can greatly reduce the egg breakage rate. But be sure to pay attention to the amount of additives to prevent them from being counterproductive. 4. Reasonable use of mineral feed During the hot season, the content of phosphorus in the diet should be appropriately increased (phosphorus can relieve heat stress). At the same time, the calcium content in layer diets can be increased to 3.8% to 4%. The ratio of calcium to phosphorus is 4:1. However, too much calcium in compound feeds will affect the palatability. In order to increase the intake of calcium without affecting the palatability of the layer feed, in addition to increasing the amount of calcium in the feed, they can be supplemented separately and allow the chicken to feed freely. Meet their physiological needs. 5. Pay attention to add flavored feed In summer, the temperature is high and the feed intake of chickens is reduced. Adding certain seasoning feeds to the feed will greatly help increase feed intake. Therefore, in order to improve the palatability of feed and increase appetite, it is necessary to use a safe and effective flavoring agent such as Fen-flavor, para-aminobenzoic acid, and sodium glutamate to increase feed intake on the premise of guaranteeing feed quality. 6. Adjust the time to feed the feed During the production, the number of feedings can be appropriately increased. In the summer and early evening, the temperature is relatively low. At this time, the feed intake of the layer is relatively large. The feeding time can be adjusted, and the feeding time can be adjusted before the light is turned off in the morning and evening to ensure that the chickens are harvested. Eat enough feed. In addition, some Chinese herbs can also be used to relieve or treat heat stress, such as Xiaoshusan, which is mixed with millet, honeysuckle, isatis root, herb, gentian, etc., and added to the feed at a proportion of 1%. The effects of heat-clearing and heat-clearing and detoxification and detoxification have no side effects.
