NPH-type (medium to long action) insulin was injected subcutaneously once per day for 2 days into 10 California breed rabbits during 3 different lactation stages. Milk lactose and protein content both increased (2.4 vs. 3.1 and 14.1 vs. 15.1% resp.) significantly when insulin was injected during the lactation-peak stage. The calculated efficiencies of milk yield/kg body wt were improved by insulin injection during the late pregnancy stage as well as the lactation-peak stage.
