Extract

It is widely recorded that placental weight varies a great deal in uniformly treated ewes, yet this variation remains unexplained (Mellor, 1983). The aim of this experiment was to assess the effects of differing parameters on birth weight, placental weight, and number and weight of cotyledons in Texel ewes carrying the Booroola fecundity gene.
