Prevalence of Diseases in Broilers Age Group 1-14 Days at Chitwan District, Nepal

Abstract

This study was undertaken to find out the prevalence of diseases in broilers age group 1-14 days at Chitwan district, Nepal. This subjective study was carried out using the secondary data retrieved from National Avian Disease Investigation Laboratory (NADIL). Chitwan and Veterinary Teaching Hospital (VTH), Agriculture and Forestry University (AFU), Rampur, Chitwan in last two years viz. June 2016 to June 2018. The cases recorded were categorized and those up-to age 14 days old broiler chicks (n=1112) were selected for the study. Data and Informations were entered in Microsoft Excel 2010 and analyzed using SPSS ver. 22. Results illustrates that the average flock size was 913.51± 918.49 with a range from 30 to 10000 chicks. The case was reported highest in 14th day followed by 12th and 10th day. The prevalence of bacterial disease was found to be highest (57.46%) followed by mycoplasma infection (10.61%) and metabolic diseases (10.16%). Prevalence of Colibacillosis was highest (43.25%) followed by Salmonellosis (12.85%) and Chronic Respiratory Disease (CRD) (10.61%). The level of chicks’ average mortality was 2.14% of total flock size. The Pearson’s correlation between flock size and mortality was found to be 0.82, which was highly significant (p<0.01). The mortality varies significantly (p<0.01) with change in seasons, the prevalence of disease was higher in summer (32.28%) followed by winter (29.13%). Prevalence was recorded as 65.19% among age group 8-14 days and followed by 1-7 days age group (34.80%). Thus, disease management during second week followed by the first week can decrease the disease prevalence and mortality of chicks and increase the efficiency of farm.

Risk Factors Associated with Avian Influenza Subtype H9 Outbreaks in Poultry Farms of Central Lowland Nepal

“…The poultry sector provides more than fifty thousand permanent jobs and nearly half a million temporary jobs in Nepal [ 15 ]. Since the past three decades, the poultry sector is rapidly commercializing, making it nearly self-sufficient to fulfill the demand in eggs and broiler meat in Nepal [ 16 ]. However, there are several challenges in farm management and biosecurity measures implementation, resulting in high average mortality rates of poultry: 12.8% in broilers, 9.2% in layers, and 7.0% in breeders [ 15 ].…”

Situation analysis and kap on antimicrobial use and resistance among veterinarians and broiler poultry farmers of Nepal

“…A previous KAP study in Bangladesh demonstrated that the age of farmers and their farming experience influence AMU and AMR in poultry production (Hassan et al, 2021). This study observed that the mean mortality of broiler poultry flocks was 9.3±15.5%, which was slightly lower than in the previous study (Subedi et al, 2020;Sarker et al, 2022). The decrease in poultry mortality could be due to many reasons, such as the use of antimicrobials for prophylaxis, improvement of farm sanitation, increase biosecurity measures, and the availability of high-quality commercial feed and treated water.…”
