The Relationship between the Blood Plasma Vitamin A Levels of Sows and of their Suckling Pigs1

I. R. Sibbald, J. P. Bowland and R. T. Berg

University of Alberta2

Abstract

Data are presented to show that the vitamin A content of the blood plasma of suckling pigs is positively correlated (highly significant) with the level in the blood plasma of their dams. From these data regression equations were formulated which predict the vitamin A level in the blood plasma of suckling pigs from the vitamin A level in the blood plasma of their dams.

The most accurate prediction was made when the suckling pigs were 4 weeks of age, when a regression equation of Y=0.473X+10.8 was obtained. About 45% of the original variation could be controlled by the use of this equation.

Blood plasma level of vitamin A in the suckling pigs was unrelated to sex.
