A comparative study of pigeon mortality and nutritional analysis at doulotpur, Khulna

A study was carried out to investigate the Newcastle disease outbreak of pigeons in Khulna, from 16 to 26 November 2019. In squabs, growers, and adult pigeons, a confirmed case of PPMV-1 was found to be the cause of the observed mortality. Diarrhea (92.86%), nervous signs (28.57%), shivering (21.43%), and respiratory signs (7.14%) were among the symptoms displayed by the affected population. Notably, pigeons that had not received vaccinations had a 100% attack rate. Potential risks, like ingesting plastic and foraging for toxic substances, were revealed by an examination of the gut content, emphasizing the importance of appropriate dietary management. Acceptable quantities of lead, cadmium, arsenic, pH, nitrate-nitrogen, total dissolved solids, and ammonia-nitrogen were found in the water, indicating no direct causative relationship with water. To rectify deficits in zinc, vitamin A, vitamin C, lipids, protein, and fats in pigeon feed, a feed analysis is essential. These results highlight how important immunization, a healthy diet, and stringent biosecurity protocols are in inhibiting PPMV-1 outbreaks. Effective strategies including regular surveillance, quarantine, and comprehensive diagnostic approaches are crucial for the management and control of Newcastle disease in pigeon populations.
