| dc.description.abstract | Repeat breeding are those cows that fail to conceive after three or more regularly spaced
services in the absence of detectable abnormalities of the internal genitalia. Repeat
breeding is one of the main causes of economic loss of dairy farming all over the world
including Bangladesh also. The aim of this study was to investigate the effect of
treatment repeat breeder dairy crossbred cows with application of GnRH analogue
(Ovurelin®
) through IM/route in thoracic region (neck muscle) at two hours before
artificial insemination, and determination of pregnancy rates in case of repeat breeder
cows. Determination to the prevalence of repeat breeding in cows, the data were
collected by using questionnaire from 57 small scale house hold dairy farms and 189
were registered cows among them 40 crossbred dairy cows selected with a definite
history of repeat breeding and had a history of 4-6 infertile services but clinically free of
diseases were selected as a repeat breeder cow for further study. The animals were
divided into two groups. Group A (n=30) cows were treated with GnRH (Gonadotrophin
releasing Hormone) 2.5 ml intramuscularly in thoracic region before two hours of
artificial insemination. Group B (n = 10) cows were inseminated without intervention
any treatment. The treated group (n=30) were further divided into 4 categories where
conception percentage 43 in single AI group, 71 percentage in the group of combination
with penicillin, 50 percent in the group of double dose of AI and 50 percentage the group
performed two times AI at 8 hours interval. The overall conception percentage was
observed 54 in treated group and 20 percentages in control group. The results indicated
that the pregnancy rate in crossbred cows could be improved by the GnRH treatment.
The higher dose of GnRH significantly increased (P < 0.05) the first service as well as
overall pregnancy rate in a dose dependent manner in repeat breeder crossbred cow bred
previously unsuccessfully. The study was concluded that GnRH is effective in the
treatment of repeat breeding cows for achieving conception. | en_US |
