The effects of feeding propylene glycol to ewes during late pregnancy and early lactation
Published online by Cambridge University Press: 20 November 2017
Extract
The pregnant uterus has a requirement for glucose that rises rapidly towards the end of pregnancy (Robinson et al., 1977). Despite this, the dry matter (DM) intake of the ewe is often depressed during this period causing excessive mobilisation of adipose tissue and an increased concentration of plasma ketones. Propylene glycol resists fermentation in the rumen and following absorption is converted to glucose and glycogen (Andrews, 1982). There is little data available on how in feed inclusion of propylene glycol affects the productivity and energy metabolism of late pregnant and lactating ewes.
