Özet: In general, seasonal breeding cycles of goats also lead an obstacle to planned and / or intensive production in goat farming. As a consequence of the seasonal breeding, products derived from goats are seasonal. However, there are various reproductive strategies available to induce out-of season production. One of them is hormonal methods which are unnatural, and expensive, and which can also disrupt the endocrine regulation of animals in repeated treatments for control of reproduction. Because of all these disadvantages of hormonal methods, it is proposed to use natural methods such as “buck effect" in order to control reproductive functions of goats. Buck re-introduction after isolation period can stimulate the oestrus and ovulation in anoestrous does. The “buck effect” refers to the reaction of does to re-introduction of males after complete isolation for at least a month. Although the “male effect" has been defined since the 1940s, in recent studies have been showed that different approaches may be involved in the formation and effectiveness of the male effect. In this study, the new perspectives of using “buck effect” as a ‘clean, green and ethical’ method of controlling reproduction are reviewed and some suggestions are presented.
