First, the salt content is too high. In order to enhance appetite and prevent feathering and licking, some chicken farmers add too much salt to their diets, which can cause severe diarrhea in chickens. The large amount of fishmeal added or the salt content of the fishmeal itself is also likely to cause excessive salt content in the feed, leading to diarrhea in laying hens.
Second, the amount of stone powder is too high. If the amount of stone powder in the diet is excessively increased or increased too quickly, the blood calcium of the layer will be too high, the burden on the kidney will be increased, and the kidney swelling will be caused, eventually leading to diarrhea. The stone powder in the hen's diet must gradually increase with the increase of the egg production rate.
Third, the crude protein level is too high. Some breeders often increase the proportion of soybean meal added to the diet in order to produce more eggs. Soybean meal content is too high, the body's absorption is not complete, thus stimulating the intestinal metabolism, causing the chicken's faeces yellow hair thin. The average protein requirement for egg-laying flock is about 16%, and protein content is too high or the protein-energy ratio imbalance may cause the liver and kidney function of laying hens to weaken, resulting in large deposition of urate and even gout.
