| Group A (overfed)
|
Received concentrates throughout pregnancy Had the only kidding problems in the study Kidding problems were due to large fetuses - 2 of the 5 does required Caesarian section Absolute fetal oversize occurred when the fetuses were 3.63 pounds. Fetal growth rate pattern in the WAD makes a high level of feeding unnecessary from days 1-70 A high level of feeding is not necessary between days 1-70 A high level of feeding is not necessary between days 120 to term |
|
| Group B | Received concentrates at optimal time for fetal growth and survival Had moderately sized kids with no problem births and no deaths Kids had the highest average daily weight gain Concentrate restrictions during pregnancy did not affect birth weights, survival or growth rates Concentrate feeding between days 61-120 is the most important period for strong, survivable kids |
|
| Group C (underfed) |
Received less concentrate days 61-120, part of the critical period of
fetal growth (days 90-120) Had very low birth weights, weak kids at birth and the only deaths in the study (45% died) Neonatal death was preceded by progressive weight loss and weakness - cause of death was starvation Milk production in the mothers was equal to the other groups Neonatal deaths were related to reduced concentrate feeding between days 61-120 The 5 living kids gained one-third less weight in their first month than kids in the other groups Increased concentrates in the last month did not improve birth weights, survival or growth rates |
