Reference for Bekhorot 41:2

אם תימצי לומר מטנפת חוזרת ויולדת בתוך שנתה יולדת ודאי אינה חוזרת ויולדת בתוך שנתה:

therefore, that he holds that an animal which discharges, does not subsequently give birth in the year [of its discharging]?<span class="x" onmousemove="('comment',' And in this case, it cannot bear, having given birth to three daughters in the beginning of the year. He mentions here 'discharging' because he also wishes to solve the dispute above between R. Ishmael and R. Joshua on the point whether there is a delay after a discharge as after an actual birth.');">²</span>
