First, the salt content in the feed is too high. To stimulate appetite and prevent feather pecking and licking, some poultry farmers add excessive amounts of salt to the diet. This can lead to severe diarrhea in chickens. Additionally, the use of large quantities of fishmeal or the naturally high salt content in some fishmeal can also contribute to an over-salted diet, which may cause digestive issues such as diarrhea in laying hens.
Second, the amount of limestone powder (stone powder) in the feed is too high. If the limestone is added in excess or increased too rapidly, it can result in elevated blood calcium levels, placing extra strain on the kidneys. This may lead to kidney swelling and, ultimately, diarrhea. It's important to gradually increase the limestone content as the hen's egg production rises to maintain a balanced mineral intake.
Third, the crude protein level in the feed is too high. Some farmers try to boost egg production by increasing the proportion of soybean meal in the diet. However, if the soybean meal content is too high, the chicken's digestive system may not fully absorb the protein, leading to increased intestinal activity and yellow, thin feces. The average protein requirement for a laying flock is around 16%. Exceeding this level or having an imbalanced protein-to-energy ratio can weaken the liver and kidney functions of the hens, resulting in the accumulation of uric acid and even gout.
In addition to these factors, improper feeding schedules, sudden changes in feed type, or poor-quality ingredients can also contribute to digestive problems. Ensuring a well-balanced diet, gradual adjustments, and high-quality feed are essential to maintaining the health and productivity of the flock. Regular monitoring of the birds' condition and adjusting the feed accordingly can help prevent many of these common issues.
