Title: The effect of pregnancy on the interval between one oestrus and the next in the tammar wallaby, Macropus eugenii. Author: Merchant JC. Journal: J Reprod Fertil; 1979 Jul; 56(2):459-63. PubMed ID: 480304. Abstract: In females mated to vasectomized males the interval between oestrous periods was 30.6 +/- 1.17 (s.d.) days but when mated to intact males and pregnancy intervened, it was 29. +/- 1.26 days (P less than 0.0025). After removal of pouch young, females carrying diapausing blastocysts gave birth 26.2 days later and came into oestrus 26.4 +/- 0.57 (s.d.) days later. When post-partum fertilization was prevented, removal of pouch young was followed by oestrus 30.4 +/- 0.99 days later (P less than 0.0005). These results indicate an influence of the conceptus upon the oestrous cycle of Macropus eugenii.[Abstract] [Full Text] [Related] [New Search]
