INFLUENCE OF PLASMA PROGESTERONE LEVEL AND CERVICAL MUCUS FERN PATTERN AT OESTRUS ON CONCEPTION RATE IN BOVINES

Abstract

It is essential that the insemination should be done at the optimum time to obtain higher conception rates. Many workers reported that conception rates were higher in bovines when inseminations were carried out at low progesterone levels (Appleyard and Cook, 1976; Antal et al., 1987). However, the cost and time involved in the estimation of progesterone limits its use in routine Al.
