[Synchronization of estrus in heifers with BOVISYNCHRON].
Copyright policy )[Synchronization of estrus in heifers with BOVISYNCHRON].
Heifers were each given 2ml of 1% solution of chlormadinone (CAP, Bovisynchron) for 15 days. Those in group I received one daily dose, while group II received half the dose twice a day. Oestrus was synchronized in all but two heifers. In group II there was a concentrated occurrence of oestrus, so that all heifers could be inseminated on the 5th and 6th days, and earlier inseminations were not needed. This decreased the time required and the number of semen pellets. Results of insemination in two of the three subgroups of group II were 51% in one and 61% in the other, compared with between 32 and 39% in the other subgroup and in group I. Ways of improving the results are discussed.
