1. Appropriate increase in nutrient concentrations in feeds Production practices have demonstrated that the addition of 1.5% cooked soybean oil to feed during the summer high temperatures can significantly increase the egg production rate. At this time, the amount of cereal feed such as corn should be appropriately reduced, generally 50% to 55%, and the nutrient concentration of the feed should be appropriately increased.
2. Increase the supply of protein feeds in summer, as appropriate, and reduce the feed intake of chickens. Only by increasing the protein levels in the diet as appropriate, and ensuring the balance of amino acids, can the protein requirements of the chickens be met. The protein content of laying hens in this season should be increased by 1-2% compared with other seasons, reaching over 18%. It is necessary to increase the amount of feeds for cakes, such as soybean meal and cotton cakes, in formulated 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 the data, adding 0.04% Bacillus Peptide to the diet can maintain the balance of intestinal flora, promote nutrient absorption, increase feed conversion rate, and also have anti-stress effect. Adding 0.1% fumaric acid to feed or drinking water can effectively relieve heat stress, increase chicken feed intake and increase egg production. Add 0.3% sodium bicarbonate to the feed (first dissolve in water and then mix, feed 10 to 15 minutes later), which has a significant effect on improving the heat resistance and egg production rate of laying hens. Reduce egg breakage. But be sure to pay attention to the amount of additives to prevent them from being counterproductive.
4. Appropriate use of mineral feeds in the hot season to properly increase the phosphorus content in the diet can play a role in relieving the heat stress, and the calcium content in the layer diet can be increased to 3.8% to 4%, maintaining the calcium and phosphorus of 4:1. proportion. Excessive calcium content in formulated feeds will affect palatability. To increase the intake of calcium without affecting the palatability of layer chicken feed, in addition to increasing the amount of calcium in feed, it can also be supplemented separately, allowing the chicken to eat freely to meet Its physiological needs.
5. Pay attention to the addition of seasoning feeds. When summer temperatures are high, adding a certain amount of seasoning feeds to feeds will greatly help increase feed intake. Therefore, in order to increase the appetite of laying hens, it is necessary to use a safe and effective flavouring agent such as Fen-flavoring, para-aminobenzoic acid, and sodium glutamate to increase feed intake on the premise of guaranteeing feed quality.
6. Appropriately increase the number of feedings The temperature in the morning and evening in summer is relatively low. At this time, the feed intake of laying hens is relatively large. You can feed them once before turning off the lights in the morning and evening to ensure that the hens feed enough feed.
In addition, some Chinese herbs can also be used to relieve or treat heat stress. For instance, Xiaoshusan made from the blending and grinding of musk, honeysuckle, isatis root, herb, gentian, etc., is added to the feed in a proportion of 1%. Formulas not only have the effects of heat-clearing and heat-clearing, detoxification and dampness, but also have no side effects.
