CURRENT THERAPY OF REPEAT BREEDING IN CROSS-BRED DIARY COWS WITH DILUTED POVIDONE IODINE

Abstract

This study was carried out to examine treatment of repeat breeder (RB) dairy cows
with diluted Povidone iodine (2%). Sixty cross-bred dairy cows suffer repeat
breeding were used to investigate the efficacy of intra-uterine infusion of diluted
Pvidone iodine for treatment of repeat breeding in dairy cows. Uterine swabs were
collected from uteri of the candidate cows prior treatment. After bacterial culture the
uteri of the selected cows were found mildly infected (subclinical endometritis).
They were then divided randomly into three equal groups. Group A (n = 20 cows)
was intra-uterine infused with 2% Povidone iodine 6 hours pre-insemination. Group
B (n = 20 cows) was infused with the same solution 6 hours post-insemination.
Group C (n = 20 cows) was left without treatment to serve as control. The potency
and efficacy of diluted Povidone iodine to cure repeat breeding in dairy cows was
evaluated by studying three parameters, the days open (DO), rate of service per
conception and the calving interval (CI). The results of this study revealed that, the
DO, rate of service per conception and CI were significantly (P<0.001) reduced by
intra-uterine infusion of diluted Povidone solution 6 hours pre and post insemination
as compared to the control.
It is concluded that, the repeat breeding (RB) syndrome in cross-bred dairy
cows is most likely to be due to sub-clinical endometritis of the reproductive tract as
well as deficiency of Iodine. Furthermore, intra-uterine infusion of 2% Povidone
iodine can be used successfully to improve the reproductive efficiency of RB dairy
cows
