Prevalence and Risk Factors of Repeat Breeding in Commercial Dairy Farms of Chittagong District of Bangladesh

Abstract

The study was conducted to measure the prevalence of repeat breeding cows and to identify the potential risk factors of Repeat breeding syndrome in commercial dairy farms at Chittagong of Bangladesh during July 2011 to October 2012. A total of 15 government registered dairy farms having 283 cows were surveyed for individual and farm level variables identified using preset questionnaire. Out of them 56 dairy cows was sampled for bacteriological exploration and culture sensitivity test. Overall prevalence of repeat breeder cow in commercial dairying of Chittagong was 11.3%. The univariate analysis screened potential cow level exposure high yielding cows (p=0.02) and cows having peripartum events (dystocia) in last calving (p=0.001). Among farm level exposures, owner educational level (p=0.05), nature of feed offer at farm (p=0.06) were evident to be potential screened factors for repeat breeding. From the 32 repeat breeders, Staphylococcus spp. 13 (40.6%) was isolated as predominant bacteria followed by Escherichia coli 8 (25%), Bacillus spp 6 (18.8%), Corynebacterium spp 6 (18.8%) and Pseudomonas spp 5 (15.6%). The isolates of bacteria were more or less effective against eight antibiotic agents. Gentamicin 36 (97.3%) showed higher sensitivity followed by ceftriaxone 33 (89.2%), chloramphenicol 33 (89.2%) indicates the effectiveness of these antibiotics in treating repeat breeding. Moreover, the identified potential risk factors should be controlled to minimize the economic loss of dairy farms.

“…Many other studies also supported the present finding of highest sensitivity for ciprofloxacin as 75 per cent (Moharana et al, 2000), 83.33 per cent (Ingawale et al, 2003), 93.75 per cent (Mane et al, 2009), 75 per cent (Reddy et al, 2012), 71.05 per cent (Bhat et al, 2013) while Nath et al, (2014) and Rohit et al, (2019) reported lower sensitivity of 45.90 per cent and 63.50 per cent, respectively than the present study. Zaman et al, (2015) also observed highest sensitivity for ciprofloxacin and enrofloxacin (100%).…”

“…While Udayavel et al, (2013) observed lower sensitivity (32%) to enrofloxacin. Bhat et al, (2013), Kavyashree (2013), Udhayavel et al, (2013) and Nath et al, (2014) reported that large number of isolates was sensitive to ceftriaxone (67.11%, 40.26%, 64.00% and 89.20%, respectively) than observed in the present study. Less number of isolates (10.17) were sensitive in the studies by Rohit et al, (2019).…”

“…However, according to Nath et al . [ 28 ], higher experience in animal husbandry can help breeders in overcoming the challenges that arise when managing the farm. This agrees with our result that breeding experience has a significant relationship with the occurrence of repeat breeding.…”

A Study on Farming Conditions and Production Performance of Available Genotypes under Commercial Dairying of Chittagong Bangladesh

“…Private entrepreneurs and some Non-Government Organizations (NGOs) mainly operate the diary sector in Bangladesh. Chittagong is the second largest city of Bangladesh and a dense of dairy zone (Nath et al, 2014). Not only that, Chittagong is one of the dairy producing emerged areas of Bangladesh, where dairy farming has been traditionally an important and major component.…”
