I. Properly increase feed nutrient concentration
Production practices have demonstrated that the addition of 1.5% cooked soybean oil to the feed during the high temperature season in summer 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.
Second, increase the protein feed supply as appropriate
In hot summer days, the feed intake of chickens is reduced. Only by increasing the protein levels in the diet as appropriate, and ensuring the amino acid balance, can the chickens meet the protein needs. The protein content of laying hens in this season should be increased by 1-2% compared to 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, with a dosage of not less than 20%-25%. The amount of animal protein feed such as fishmeal should be appropriately reduced to increase palatability and increase feed intake.
Third, careful use of feed additives
In order to avoid stress and egg production performance 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%-0.4% of vitamin C and 0.2%-0.3% of ammonium chloride in drinking water can significantly relieve heat stress.
Fourth, the rational use of mineral feed
Appropriate increase in dietary phosphorus content in hot season can relieve heat stress, and the calcium content in laying hens' diets can increase to 3.8%-4%, maintaining a 4:1 ratio of calcium to phosphorus. 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.
Fifth, pay attention to add flavored feed
Adding a certain amount of seasoning feed to the feed during the summer when the temperature is high can greatly increase the 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. Increase the number of feedings appropriately. In summer, the temperature in the morning and in the evening 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.
