“…Repeat breeding is a condition in the female cattle that fails to pregnant after being mated three times or more with a fertile bull without any observed abnormality (Amiridis et al, 2009). Repeat breeding cases are found in almost all parts of the world with the incidence ranges from 5.5-33.3% (Gustafsson and Emanuelsson, 2002;Yusuf et al, 2010).…”

This study aimed to investigate the physical property changes of cervical mucus in repeated breeder Aceh cows. Six cows consisting three normal (K1) and three repeat breeders (RB) (K2) of adult Aceh cows were used. The characteristics of K1 group were at > 2 months post parturition, successful pregnancy following once insemination, and twice regular estrus cycle twice. The K2 were cows with normal estrus but failed to be pregnant after three times artificial inseminations. Cervical mucus samples (50 ml each) were collected by aspiration using a sterile catheter and disposable syringe. The comparisons of the physical properties of cervical mucus between fertile and repeat breeder cattle were as follows.. Cervical mucus unavailability/in small quantity was 0.00 vs. 66.67%, cloudy color was 0.00 vs. 66.67%, thick consistency was 0.00 vs. 100%, fern pattern was 0.00 vs 66.67%, spinnbarkeit was 5.16±1.60 vs. 2.83±2.02 cm and pH values was 7.33±0.57 vs 9.33±1.52. in conclusion, the physical properties of cervical mucus in repeat breeder Aceh were less in quantities, more cloudy, higher in viscosity, and higher pH as compared to normal fertile cows.

“…Repeat breeding (RB), defined as cows failure to conceive from 3 or more regularly spaced services in the absence of detectable abnormalities, is a costly problem for the dairy producer [1] . The causes of this type of RB might be fertilization failure and early embryonic death [2] . Non-infectious causes are bad management, chromosomal aberrations, hormonal imbalance, anatomical defects of reproductive tract, improper timing of insemination, inadequate estrus detection, improper semen handling, infertile bulls, poor nutrition and heat stress [3] .…”

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

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.

Consequently, if the lifespan of the CL is artificially extended for some days, embryos with retarded development will possibly continue their development (Amiridis et al 2009).…”

The main objective of this study was to determine if administration of meloxicam, a cyclooxygenase (COX) two inhibitor, to heifers in which embryo transfer (ET) is more difficult and requires a greater manipulation of the tract, would be beneficial. Nulliparous recipient heifers were divided in two groups: CON (n = 102), in which animals received 10 ml of saline IM (the same volume of meloxicam) and MEL (n = 105) animals that were treated with meloxicam. According to the degree in passing the catheter, recipients from both groups were classified as Grade I, easy (< 60 s), and Grade II (more than 80 s), difficult. Immediately after embryo transfer, MEL recipients received an injection of 200 mg of meloxicam (10 ml).There was no difference in the pregnancy rates on Day 35 considering animals which presented Grade I cervix independently whether the treatment was performed or not (p = 0.22). There was a statistical difference in the pregnancy rates (p < 0.01) between both groups (49.0% and 66.7% for CON and MEL, respectively) when cervical grade was not considered, on Day 35. Considering the animals that presented Grade II cervix, the pregnancy rate was higher for MEL (21.15% and 78.84%, respectively) in both examinations (p < 0.01).The authors concluded that meloxicam had a positive influence on general pregnancy rate of treated heifers in comparison to non-treated heifers. It was also observed that pregnancy rate was not influenced by meloxicam administration in Grade I heifers. Treatment increased the pregnancy rate of Grade II heifers.
