Citric acid feeds chicken well
The citric acid mixture was fed to chickens. According to Gao Lunlun, a young scientific and technical farmer and a chicken farmer at Shanshanhou Village, Shancheng Street, Shanting District, Zaozhuang City, Shandong Province, the chicken was fed with citric acid to enhance the disease resistance of the chickens. Raising hens' egg production rate can also promote chick weight gain. 1. Specific method: Adding 14 grams of citric acid per kilogram of feed (chemically pure) can increase the egg production rate of 7-month-old hens from 81% to 95%, an increase of 14%. Adding 20 grams of citric acid per kilogram of feed (chemically pure) can increase the daily gain of 20-day-old fattening cocks from 6 grams to 8 grams, an increase of 33.3%. 2. Effect: The addition of citric acid to feed can reduce the pH of the chicken stomach, enhance the activity of digestive enzymes, increase the absorption of nutrients in the digestive tract, and facilitate the digestion of feed.
