Zinc and sulfur are trace elements necessary for the growth and breeding of livestock and poultry. It is indispensable in livestock and poultry feed. 2zw China Feed Industry Information Network - based on feed, serving animal husbandry

When the zinc deficiency in the feed or the zinc in the feed is not easily absorbed by the livestock, the zinc deficiency will occur in the livestock, causing the body of the livestock to lose weight, the outer skin to thicken, and the testicles of the breeding and breeding birds to shrink significantly. Less sperm, growth and breeding are affected. Therefore, livestock and poultry feed should not be deficient in zinc. In some zinc-poor livestock and poultry feeds, zinc should be properly supplemented. The method is to mix it with zinc sulfate or zinc carbonate. The amount to be supplemented may vary depending on the species and growth period of the livestock. Generally, the amount of zinc sulfate or zinc carbonate added per kilogram of feed is: 50-60 mg of pigs within 20 kg, 40-50 kg of pigs and 40-50 mg of pregnant sows, and 50-100 kg of pigs. 30-50 mg, 40-60 mg of lactating sows; 30-50 mg of rams, 30-60 mg of calves, 40-60 mg of young cows, 40-60 mg of fattening calves, 90 mg of beef and beef, meat 100 mg of young cows; 30 mg of sheep; 50-100 mg of poultry. If the livestock and poultry have symptoms of zinc deficiency, the amount of addition can be increased by 0.5 to 1 times. While adding zinc sulphate or zinc carbonate to the livestock feed, it is also necessary to adjust the food intake of calcium and zinc in the livestock and poultry, so that the calcium content in the feed is maintained at a level of 0.65% to 0.75%. In this way, the purpose of zinc supplementation for livestock and poultry can be truly achieved. 2zw China Feed Industry Information Network - based on feed, serving animal husbandry

Sulfur in livestock and poultry feed can promote the synthesis of protein in the body of livestock and poultry and improve the protein content of livestock and poultry products. For the lack of sulfur in livestock and poultry feed, the sulfur content can be increased by adding sodium sulfate. The amount added is generally 3 to 5 grams of sodium sulfate per kilogram of livestock feed. After adding sodium sulfate to livestock and poultry feed, its yield and quality can be significantly improved. For example, pigs can increase weight by 8% to 11%, increase lean meat rate, and have good meat quality; egg production rate of laying hens can be increased by about 20%; hair production of long-haired rabbits can be increased by 12% to 18%; The milk yield can be increased by 1 to 1.4 kg, and the feed conversion rate can be increased by 60%. The effect is better. 2zw China Feed Industry Information Network - based on feed, serving animal husbandry
