Endometrial Regeneration and Conception Rate Following Oestrus Induction with Ovsynch Treatment in Normally Calved and RFM Treated Cows

Fixed time breeding programmes in cows, buffaloes, goats and sheep: A review

“…Deficiency of calcium, phosphorus, iron, zinc and copper in blood have been reported to be a predisposing factors for the occurrence of retention of fetal membranes and repeat breeding in dairy cattle [43,44] . RFM resulted in a delayed renewal of the ovarian activity and an increased interval between the parturition and the first ovulation [39] . Delay in puberty delays the conception and results in low reproductive efficiency in bovines.…”

“…It was concluded that administration of vitamin A prior to ovsynch programme altered the secretory pattern of estrogen and progesterone and further improved the pregnancy rate in repeat breeding cows [38] . Endometrial biopsy is a valuable tool to predict the healthiness of endometrium to decide upon the future fertility before start of estrus induction programme in sub-fertile of infertile cows or buffaloes [39] . Histopathological changes of uterine endometrium in normally calved and retained fetal membranes (RFM) treated cows indicated that increased conception rate in postpartum normally calved than the RFM treated cows positively correlated with the healthy endometrial lining and glandular development [40,41,42] .…”
