Nutritional effect of sodium sulfate concentration meter for the poultry. Sulfate sulfur element in 10%, one of the mineral sulfur is necessary for animal, animal sulfur 15%, poultry exists mainly in the form of organic sulfur in methionine and cysteine in sulfur-containing amino acids, such as poultry by sulfur-containing amino acid body protein synthesis, feathers and other body tissue. After analysis, the feathers of poultry and eggs, chicken and other products contain more sulfur. Add sodium sulfate not only provides sparse elements also provide steel elements, when feed when you need to increase the uranium content, you can add sodium thiosulfate, add sodium sulfate does not increase the chlorine content. Domestic tests also confirmed that add sodium sulfate in livestock and poultry feed, can significantly improve the performance of livestock and poultry. As Wang Yingbo (1995) show that the feed add 0.3% sodium sulfate to raise egg 2.4%, egg weight increased by 3.7%, benefits 10.6%. Sun Yanming (1997) proved in the hot season, joined the 0.05% sulfate in chicken water, improved laying rate is effective; Huang Chuen refusing (1997) experiments, feather pecking chicken feed in 1% sulfate, after 3 days of work, 5~ 6 days stop feather pecking, 15~ after 21 days, chickens Peck was Director of new feathers, later changed to 0.3% ~ 0. Amount of 4%, increase feed intake of the chicken, egg-laying rate of 12% ~ 15%; Peck in dietary sodium sulfate on control pain in anus-preserving solution and fresh eggs have a pronounced effect. Jingbai chicken tests show that supplement in 0.3% sulfate works best; Ukraine experts say chicken feed in 0.5% sulfate, to raise egg 15% and add 0.4% egg duck, egg production rate is the highest.
