The effect of a progesterone (P4) intravaginal device (CIDR) on resynchronisation of oestrus and embryonic loss in previously timed inseminated dairy heifers
Abstract:A study was done to evaluate the effect of using progesterone (P 4 ) intravaginal device (CIDR: controlled internal drug-releasing dispenser) to synchronise the return to oestrus of previously timed inseminated (TAI) dairy heifers, and to evaluate embryo survival and pregnancy rate (PR) in the return to oestrus heifers. At the onset of the artificial insemination (AI) breeding period (day 29), heifers were randomly assigned into two groups (treated group CGPG, n 5 79) and (control group GPG, n 5 83). Every hei… Show more
