红鹿（C.在下一个繁殖季节，母鹿的身体状况、存活率和繁殖力下降。成功繁殖对繁殖力的影响受种群密度、母亲年龄、小牛出生日期和性别的影响。相比之下，在1年的成功繁殖对出生体重，生存或生长的任何小牛产生的下一个赛季，显然是因为非繁殖（产）母鹿失去了更高比例的身体储备在冬季的几个月比成功的育种（母鹿）。虽然在小牛出生后的第二年再次怀孕的母亲比那些未能再次繁殖的母亲更早地断奶，但这种差异对前一个小牛的生存没有明显的影响。母鹿的母系群体的规模的增加降低了其成员的生殖性能。这种影响应包括在成功繁殖的成本中。
Successful reproduction by red deer (C. elaphus) hinds reduced the mother''s body condition, survival and fecundity during the next breeding season. The effects of successful reproduction on fecundity were modified by population density as well as by the mother''s age and the birth date and sex of her calf. In contrast, successful reproduction in 1 yr had little effect on the birth weight, survival or growth of any calf produced the following season, apparently because non-breeding (yeld) hinds lost a higher proportion of their body reserves during the winter months than successful breeders (milk hinds). Although mothers that conceived again in the year following the birth of a calf weaned their calves earlier than those that failed to breed again, this difference had no obvious effect on the survival of the previous calf. Increases in the size of matrilineal groups of hinds reduced the reproductive performance of their members. This effect should be included among the costs of successful reproduction.
