Uterine Environment and Breed: DISCUSSION(2)


Also, liver weights were smaller on Day 24 in MS than WC with placental weight as a covariate. The physiological significance of these observations is unknown at this time, but they suggest that by growing more slowly, MS pigs may have an advantage by having more placenta per gram of fetus than do WC pigs. buy prednisone

A previous study of fetal pig hematology indicated a Day 30 erythrocyte count of 560 000/|ul1 and a hematocrit of 20.4% in Yorkshire and/or Duroc fetuses, which is similar to the values obtained in this study. However, the mean reticulocyte percentage was very low (1.10%) in that study compared to this study (~20%; Table 5) on Day 30. Another earlier study had values of 290 000 RBC/ jxl on Day 26 and 390 000 RBC/|xl on Day 32, which are similar to values in this study (Table 3), but reticulocyte percentages at those ages were much higher (99% and 100%, respectively) than observed on Day 30 in this study (Table 5). Other previous studies of pig hematology did not investigate these parameters during early gestation. The reason for these differences between studies is unknown, but they may be due to differences in methodologies.
