2. Increase the supply of protein feeds in summer when it is hot, and the feed intake of chickens is reduced in summer. Only by increasing the protein levels in the feed, and ensuring the balance of amino acids, can it satisfy the protein requirements of the laying hens. Otherwise, it will affect the production due to insufficient protein. Egg volume. 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 It is necessary to add some anti-stress additives to feed or drinking water in order to prevent stress and egg production performance of laying hens caused by high temperature and other factors. 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 should increase phosphorus content in the diet during hot season (phosphorus can relieve heat stress). At the same time, the calcium content in laying hens can increase to 3.8% to 4%. To calcium and phosphorus balance, keep the ratio of calcium and phosphorus 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 the fact that seasoned feeds add high temperatures in summer and the feed intake of chickens is reduced. Adding certain seasoning feeds to feeds 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. Adjusting time The number of feedings can be appropriately increased in the production of feeds. In the morning and in the evening, the temperature in the summer is relatively low. At this time, the feed intake of the layers is also relatively large. The feeding time can be adjusted, and the feeds can be fed before the lights are turned off in the morning and evening. Once, to ensure that chickens feed enough feed.
