The main reasons for anus prolapse of layer chicken in chicken egg layer cage
- Accepting excessive long time of illumination before starting laying egg will cause layer chicken to lay egg prematurely and then cause prolapse of the anus.
- The protein level in the diet of layer chicken is too high, and the low energy concentration will cause an increase in sexual maturity, which is easy to cause prolapse.
- Insufficient vitamin A and vitamin E in the diet of layer chicken can easily induce inflammation and cause fallopian tube stenosis and anus
- Long-time diarrhea causes excessive water consumption in the layer chicken’s body, resulting in severe dehydration, and the inability to secret lubricate fluid effectively in the fallopian tube mucosa. The dry reproductive tract will cause anus prolapse of layer chicken when they lay eggs.
- The chickens are crowded and the stocking density in chicken egg layer cage is high. During egg-laying, the fallopian tubes or cloaca are damaged by scraping and inserting by the cage wire, which makes it difficult to reset and causes inflammation and leads to prolapse of the anus.
- Environmental factors and pathological factors are also the main reasons for prolapse of layer chicken. Such as poor ventilation, poor sanitation, etc.; diseases such as Salmonella, Escherichia coli, etc.
