Twin-bearing ewes in late pregnancy have the same energy requirements as single-bearing ewes.

Question

BlackTom AI · Accepted Answer

Restating the question and options for clarity: Twin-bearing ewes in late pregnancy have the same energy requirements as single-bearing ewes.
Option 1: True. This statement is incorrect because twin-bearing ewes have higher energy needs than single-bearing ewes, especially in late pregnancy when fetal growth and uterine/placental demands are greater. Assuming equal energy requirements ignores the additional calories required to support two fetuses, which can lead to undernutrition and poorer lamb outcomes if not adjusted.
Option 2: False. This statement is correct because energy requirements increase with litter size and stage of pregnancy. In late gestation, twin-bearing ewes typically require significantly more energy to support fetal growth, maintain maternal tissue, and prepare for lactation, compared with single-bearing ewes. Treating both groups as having identical energy needs fails to account for these physiological demands.
Notes on potential misconceptions: Some might think energy needs are driven only by body weight or by time in gestation alone, but litter size adds a substantive extra requirement. Others might assume incremental differences are small, but studies and standard reproductive nutrition guidelines show meaningful increases for multiples. Finally, always consider adjusting intake based on monitoring body condition and production goals rather than relying on a one-size-fits-all plan.
