Since the hen chicken feed must pay attention to a reasonable proportion, the main performance is:
First, the crude protein level is too high Some farmers in order to allow chickens to produce large eggs, often increase the proportion of dietary soybean meal. Soybean meal content is too high, the body's absorption is incomplete; protein content is too high or protein-energy ratio imbalance can lead to decreased liver and kidney function in laying hens, resulting in a large number of deposition of urate or even gout.
Second, the excessive addition of stone powder in the amount of stone powder in the diet is too much or too fast, it will lead to high blood calcium layer, kidney burden, causing kidney swelling, leading to diarrhea, with the egg production rate increased step by step increase. When the body weight reaches the standard, it is added 105 days, the first time is 3%, and the egg production rate is 20% before it is added to 8%.
Third, excessive salt content to enhance appetite, to prevent the emergence of feathers, some chicken farmers add too much salt in the feed, so that chickens will have severe diarrhea.
