Trans-generational effects of nutrient restriction during early and mid-pregnancy on female reproductive function in Scottish Blackface and Suffolk sheep
MetadataShow full item record
While several studies have assessed the effects of under-nutrition during pregnancy on foetal and offspring gonad development, few have addressed the reproductive performance of offspring as adults, or whether the developing reproductive axis of different genotypes responds differently to comparable nutritional stress. We have recently demonstrated that nutrient restriction during pregnancy has differential effects on lamb birth weight and faecal eggs counts at weaning in Scottish Blackface and Suffolk sheep breeds (Rooke et al., 2010), suggesting that effects of nutrition on foetal development differ between breeds. Furthermore, it has been proposed that females in better body condition produce more female than male progeny (reviewed by Rosenfeld and Roberts, 2004). This study investigated the effects of undernutrition during early and mid-pregnancy on the development of the reproductive axis in both sexes and the reproductive performance of female offspring in two contrasting commercial breeds of sheep.
