Examines the effect of two dosages of PMSG on the onset of estrus and twinning in an African breed of sheep whose estrus was synchronized using either intravaginal progestogen sponge or prostaglandin F2 alph. Table 1 summarises the results of the study. Most ewes (>75 percent) manifested estrus w...

Results of a study conducted to determine the conception rates of Boran cattle following artificial insemination of different times from the onset of induced oestrus compared with artificial insemination following natural oestrus.

A study undertaken to characterise the oestrous cycle in Zebu cows following oestrous induction with PGF (Prostaglandin F2alpha) and examines the function of the subsequently formed CL (corpus luteum) by monitoring levels of peripheral plasma progesterone.

This work was conducted to assist the large cattle multiplication centres to produce more animals of the genotype being demanded to improve peasant farm income, to generate an alternative way of introducing the same genotype to farmers with limited income by using artificial insemination, to assi...

The luteolytic effect of prostaglandin F2á (PGF2á) during the confirmed luteal phase of the oestrous cycle was evaluated in ten Boran and ten Boran x Friesian cross-bred heifers. Following injection with 25mg Lutalyse, animals were bled every 6 h for 96 h and plasma progesterone (P4) determined ...
