Scallion aroma, Xin Wen. It is a very wide range of vegetables and condiments that people eat in their daily lives. Traditional Chinese medicine theory and practice and modern research have proven that Welsh onion has anti-inflammatory, bactericidal and stomachic effects, cures colds and colds, and has an inhibitory effect on influenza virus. According to instrumental research data, the stems and leaves of every 100 grams of green onions contain 0.05 mg of vitamin A, 2.0 mg of vitamin C, 2.4 g of protein, 0.3 g of fat, 9.8 g of carbohydrate, 8.6 g of total sugar, and 4.6 g of calcium. Phosphorus 3.9 grams, iron 0.1 mg, a variety of amino acids 0.0298 mg, very rich in nutritional value. At present, the lack of food intake and low utilization rate in livestock and poultry farming is a major problem encountered by farmers. Studies have shown that adding a certain amount of green onions to livestock and poultry feed is an effective way to solve this problem. Because green onion leaves are rich in bioactive substances and a variety of vitamins, they can directly promote the digestion and absorption of nutrients. In daily life, people mainly eat onion stems and a small amount of onion leaves, and most onion leaves are discarded. Especially when winter onions are stored before winter, the large number of discarded onion leaves is quite considerable. The green onion leaves will be an important feed source for the development and utilization of livestock feed. Moreover, tests have shown that the addition of a certain amount of onion leaves in feed can improve the palatability of feed, increase the feed intake of livestock and poultry, promote digestion and absorption, accelerate the growth of livestock and poultry, and prevent and control the health of livestock and poultry. . With the development of animal husbandry, the development and utilization of onion additives can improve the palatability of feed, promote appetite, improve meat quality, and increase economic efficiency. It can also be used for disease prevention and treatment of livestock and poultry without drug resistance and residue. It will be teratogenic, carcinogenic, and mutagenic. Therefore, the application of green onions in animal husbandry is very promising. The discarded fresh green onion leaves were dried and dried and then processed into powder. Adding 2% green onion leaf powder to the basal diet fed daily, the egg production rate, egg weight, and feed utilization rate were significantly improved. Adding 3% green onion leaf powder to the basic diet of finishing pigs significantly increased pig feed intake, increased feed remuneration, and improved meat quality. In the rabbit raising industry, the onion leaf powder was mixed in the concentrate and fed twice a day. The rabbits were fed 40 grams each time. The young rabbits over 3 months old were fed 25 grams, and the young rabbits within 2 months of age were 10 grams. Can prevent rabbit colds, bloating, diarrhea, constipation and other diseases.
