Evaluation of techniques for estimating milk production by sows 1. Deuterium oxide dilution method for estimating milk intake by piglets
S. Prawirodigdo, R. H. King, A. C. Dunkin, H. Dove
Two experiments were conducted to determine the validity of the deuterium oxide (D2O) dilution method to estimate milk intake by pigs. A total of 39 piglets weaned from their dams 24-36 hours after birth and trained to drink from artificial nipples, were used for two experiments. Estimates of milk replacer consumption of individual piglets over 1, 3, 5 and 7 days were made by the D2O dilution method and by disappearance. Milk intakes estimated by this D2O dilution method were significantly correlated (R2 = 0.98-0.99) with milk intake measured by disappearance. The average difference between estimates by disappearance and estimates by the D2O dilution method were -1%, +0.5%, +0.5% and -2.1% for measurement period of 1, 3, 5 and 7 days respectively.
