Studies on reproduction in prolific ewes. 4. Sequential changes in the maternal body during pregnancy



Journal of Agricultural Science, UK 91(2): 291-304



78 Finnish Landrace X Dorset Horn ewes in lamb to Suffolk rams were slaughtered serially between 50 and 145 days of gestation. The mean litter size was 2.7. The daily feeding regime aimed to provide each ewe with 15 MJ of metabolisable energy (ME) in the 1st mth of gestation and 9.4 MJ in the 2nd and 3rd. Thereafter, the ewes were provided with a basal intake of either 9.6 MJ (low plane) or 13.4 MJ (high plane), plus 1.3 MJ for each foetus.
