Evaluation of different parameters in relation to repeat breeding of cows at the Coastal areas of Bangladesh

Abstract

The aim of this study was to evaluate the presumptive factors might be responsible for repeat breeding syndrome of cows in Bangladesh. The study was conducted in different villages around the Faculty of Animal Science and Veterinary Medicine, Patuakhali Science and Technology University, Outer campus, Barisal during the period from July to September 2017. A total of 100 repeat breeder cows were evaluated considering different presumptive influencing factors such as breed, age, parity, body condition score (BCS), fetal death, retention of placenta, post-partum endometritis, abortion, dystocia and managemental practices of cows. It was found that there was no significance (p>0.05) effect of parity and age of cows on the occurrence of repeat breeding syndrome in local and crossbred cows. Repeat breeding syndrome was significantly higher in BCS 2.0 to 2.5 in local breed and 3.0 to 3.5 in crossbred cows than that of other groups. In the study animals, dystocia was 4.0%, fetal death was 58.2%, retention of placenta was 57.1%, post-partum endometritis was 4.1% in crossbred cows. Cows in semi-intensive system raring had significantly (P<0.05) higher (53.1%) of repeat breeding than that of others systems. Animals that were not dewormed (73.5%) and vaccinated (92.9%) had 73.5 % and 92.9% repeat breeding syndrome affected cows, respectively. It may concluded that simultaneously multiple factors such as irregular deworming and vaccination, subclinical endometritis, hormonal imbalance, early embryonic death due to low progesterone level, failure of proper heat detection and so on, might be also responsible to the occurrence of repeat breeding syndrome in cows.Res.

Feeding and Breeding Management Practices of Dairy Animals in Muzaffarnagar District of Uttar Pradesh

“…Overall, 70% of dairy animals suffered from repeat breeding problems followed by 25% repeat breeding with anestrous and only 5% animals with repeat breeding and frequent vaginal discharges (Table 1). Similar findings were also reported by Matubber et al, (2018) who found that 73.5% dairy and animals suffered from repeat breeding problem. Multiple factors such as irregular deworming and vaccination, deficiency of mineral, hormonal imbalance, failure of proper heat detection, etc., generally responsible for the incidence of repeat breeding in dairy animals.…”

The Blood Biochemical Profile in Aceh Cows With Repeat Breeding

“…Kejadian RB pada sapi disebabkan oleh banyak faktor di antaranya faktor manajemen pemeliharaan, nutrisi, infeksi, dan hormonal (Barui et al, 2015;Ramandani dan Nururrozi, 2015;Matubber Matubber et al, 2018). Defisiensi nutrisi telah dilaporkan sebagai faktor utama penyebab gangguan reproduksi pada sapi perah (Kumar, 2014;Barui et al, 2015;Ahmed et al, 2017;Sulieman et al, 2017), dan kerbau (Akhtar et al, 2014;Saraswat dan Purohit, 2016).…”

Repeat breeding: prevalence and potential causes in dairy cows at different milk pocket areas of Bangladesh

“…age, body condition score, season, parity, lactation stage, milk yield, breed, nutritional management, bull factor, failure to fertilization, and early embryonic death (Nath et al 2014;Singh et al 2008;Saraswat and Purohit 2016;Washaya et al 2019). Some reports consider the degree of RB of dairy cows in speci c regions and fewer repeat breeder cases in Bangladesh but information relating to its prevalence and risk factors for RB is very scanty (Islam et al 2017;Asaduzzaman et al 2016;Matubber et al 2018). Hence, this study was undertaken to envisage the prevalence and potential risk factors associated with RB in dairy cows in selected milk pocket districts of Bangladesh, viz.…”
