- Too much salt
To increase appetite, prevent feather pecking and anus pecking. Too much salt is added to the chicken feed, so that the chickens drink too much water and often have strong diarrhea. In addition, excessive addition of fish meal or the added fish meal itself contains too much salt, which can easily lead to excessive salt content in the feed and cause diarrhea in laying hens.
- The amount of stone powder added is too high
Adding too much stone powder in the diet or increasing too fast will cause the blood calcium of the laying hen to be too high, the burden on the kidneys will increase, and the kidney will be swollen. Eventually cause diarrhea. In order to meet the needs of laying eggs, the amount of stone powder added in the diet of laying hens must be gradually increased as the laying rate rises.
- Crude protein level is too high
Some breeders want to make the chickens lay more eggs. Increase the ratio of soybean meal in the diet. The content of soybean meal is too high and the body absorbs it incompletely. This stimulates the intestines, speeds up metabolism, causes yellowing and thinning of chicken feces, and reduces the feed conversion rate. Generally, the crude protein requirement of laying hens is about 16%. Too high protein content or unbalanced egg energy ratio can easily cause weakening of the liver and kidney functions of the laying hens, resulting in a large amount of urate deposition, and even gout.
- Raw material mildew
The raw materials in the feed, such as corn, peanut meal, etc., are mildewed, and their toxins can stimulate and destroy the intestinal mucosa of the laying hens, increase the permeability of the intestinal mucosa, and cause diarrhea in the laying hens.
