When zinc deficiency in the feed or zinc in the feed is not easily absorbed by livestock and poultry, zinc deficiency occurs in the livestock and poultry, resulting in loss of body mass of the livestock and poultry, thickening of the skin, and marked shrinkage of the pellets of breeding and breeding birds. Less sperm, growth, breeding are affected. Therefore, livestock and poultry feed must not be deficient in zinc, in some zinc-deficient livestock and poultry feed, zinc should be properly supplemented. The method is to mix them with zinc sulfate or zinc carbonate. The amount to be supplemented may vary depending on the species and the growing period of the livestock and poultry. Generally, the amount of zinc sulfate or zinc carbonate added per kg feed is 50-60 mg of pigs within 20 kg, 20-50 kg of pigs and 40-50 mg of pregnant sows, and 50-100 kg of pigs. 30-50 mg, 40-60 mg for sows, 30-50 mg for rams, 30-60 mg for calves, 30-60 mg for calves, 40-60 mg for fattening calves, 90 mg for calves and beef cattle, meat Baby cows 100 mg; sheep 30 mg; poultry 50-100 mg. If livestock and poultry have symptoms of zinc deficiency, the amount can be increased by 0.5-1 times. When zinc sulfate or zinc carbonate is added to the livestock feed, the food intake of calcium and zinc by livestock and poultry is also adjusted so that the calcium content in feed is maintained at a level of 0.65-0.75%. In this way, we can really achieve the purpose of zinc supplementation for livestock and poultry.
Sulfur in livestock and poultry feed can promote the synthesis of protein in livestock and poultry muscles and increase the protein content of livestock and poultry products. For sulphur content in livestock and poultry feeds, the sulphur content can be increased by adding sodium sulphate. After the addition of sodium sulfate to livestock and poultry feed, both the yield and quality of the animal feed can be significantly improved. For example, pigs can increase their weight by 8-11%, increase the lean meat percentage, and have a delicious meat quality; the egg production rate of laying hens can increase by about 20%; the hair production of long-haired rabbits can increase by 12-18%; the daily production of dairy cows. The amount of milk can be increased by 1-1.4 kg, and the feed conversion rate can be increased by 60%. The effect is good.
Zinc and sulfur are trace elements necessary for the growth and breeding of livestock and poultry. It is indispensable in livestock and poultry feed.
