Conteúdo: |
Although there was a dramatic decline in total spermatozoa per ejaculate, concenption rates were unaffected. The fact that many ewes were mated by more than one ram and also that each ram will often mate each ewe more than once means that the total number of spermatozoa deposited in the anterior vagina has been more than adequate for normal fertility. It would seem than conventional ram/ewe ratios used under intensive farming conditions are unnecessarily high. Table 1: Percentages of ewes mated in first 17-day cycle and ?returns? to service. |
