Salt content is too high In order to enhance appetite and prevent the occurrence of cockroaches, anal and other phenomena, excessive salt is added to the chicken feed, so that the chickens drink too much water and often have strong diarrhea. In addition, the amount of fishmeal added is too large or the added fishmeal itself contains a lot of salt, and it is easy to cause the salt content in the feed to be too high, causing diarrhea in the laying hen. The amount of stone powder added is too high Too much or too much stone powder in the diet will cause the blood calcium of the laying hen to be too high, the kidney burden to increase, causing kidney swelling and eventually diarrhea. In order to meet the egg production needs, the amount of stone powder added in the diet of the laying hen must increase gradually with the increase of the egg production rate. The crude protein level is too high In order to make chickens produce large eggs, some breeders often increase the proportion of soybean meal in the diet. The content of soybean meal is too high, the body absorption is incomplete, which stimulates the intestines and accelerates metabolism, causing the chicken feces to become yellow and thin, and the feed conversion rate is reduced. Generally, the crude protein requirement of laying hens is about 16%. The protein content is too high or the egg energy ratio is unbalanced. It is easy to cause the liver and kidney function of the laying hen to weaken, resulting in a large deposition of urate and even gout. Raw material mildew The raw materials in the feed, such as corn and peanut meal, are mildewed, and the toxins will stimulate and destroy the intestinal mucosa of the laying hens, increasing the permeability of the intestinal mucosa and causing diarrhea in the laying hens.
