1. Appropriate increase in nutrient concentrations in feeds 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, if appropriate, increase the supply of protein feed during the summer days, the chicken feed intake is reduced. Only by increasing the protein level in the feed as appropriate, and ensuring the Amino Acid balance can meet the protein requirements of the laying chicken. 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 high temperature and other factors caused by layers of chicken stress response and egg production performance, add some anti-stress additives in feed or drinking water is necessary. 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 in the hot season appropriate increase in dietary phosphorus content can play a role in relieving heat stress, while laying hens dietary calcium content can be increased to 3.8% -4%, maintaining 4:1 of calcium and phosphorus 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.
Fifth, pay attention to add seasoning feeds in summer when the temperature is high in the feed to add a certain amount of seasoning feed 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. 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.
Riboflavin:
1. Participate in biological oxidation and energy metabolism in the body, and is related to the metabolism of carbohydrates, proteins, nucleic acids and fats, which can improve the utilization rate of proteins in the body, promote growth and development, and maintain the integrity of skin and cell membranes. It has the function of protecting the skin, hair follicles, mucous membranes and sebaceous glands.
2. Participate in the growth and metabolism of cells, and are essential nutrients for the metabolism and repair of body tissues, such as strengthening liver function and regulating the secretion of adrenaline.
3. Participate in the metabolism of vitamin B6 and niacin, which is a model of the coordination effect of B Vitamins. As prosthetic groups, FAD and FMN are involved in the conversion of tryptophan to niacin, and the conversion of vitamin B6 to pyridoxal phosphate.
4. It is related to the absorption, storage and mobilization of iron in the body.
5. It also has antioxidant activity, which may be related to flavinase-glutathione reductase.
