  • Title: Effects of restrictive suckling on postpartum reproductive performance in mares.
    Author: Henneke DR, Kreider JL.
    Journal: Am J Vet Res; 1979 Sep; 40(9):1281-4. PubMed ID: 525933.
    Abstract:
    Quarter Horse mares (n = 30) and their foals were used in a 2-year study. Objectives of the study were (i) to determine the effects of a treatment regimen, which permitted nursing for four 1-hour periods each day, on the postpartum reproductive performance of the dams, and (ii) to assess the effects of this procedure on the growth and development of foals. Mares in the restricted suckling treatment group showed estrus and ovulated sooner (P less than 0.01) after parturition than did control mares during the first year of the study, but not during the second year. Plasma progesterone concentrations were similar for both treated and control mares and remained less than 1 ng/ml from parturition to ovulation. Conception rates were not significantly influenced by treatment. However, two mares which had records of failing to have estrus while nursing a foal were bred and ovulated, and one of the two conceived while on the restricted suckling treatment. The absence of treatment effects on any of the variables measured in the foals indicates that restricted suckling did not impair foal growth and development.
