The hormonal treatment presently used to synchronize oestrus and ovulation are not completely effective. However, bud help to provide better control of the breeding period and allow. AI on a fixed time basic. Some modifications for improving the synchronization of ovulation are foreseen, but the cost of these modification must be considered; indeed, the piece of the treatment means that they are presently used only in dairy goats, being too expensive for mixed breeds or those that are bred for meat or fibre. Another will be to increase the time during which the spermatozoa are able to fertilise the oocytes, rather than try improve the synchronization of ovulation. The encapsulation technique could be a powerful tool for this purpose. Finally, the recent pressure in some countries to to develop organic farming is forcing us to think of non-hormonal treatments for controlling the breeding periods of farm animal. In goats, the combination of photoperiodic treatment with a male effect is an interessant possibility. However, the variability in the interval between introduction of bucks and onset of oestrus (Waltken-Brown et al., 1993) that is inherent in this approach requires the goats to be inseminated according to observed oestrus. At present, these is no alternative to hormonal treatments when AI at a predetermined time is needed. |
