A Study of Effects of Blood Types, Sires, Litter Size and Other Factors on Sex Ratios in Pigs
Abstract
dc:descriptionSex distributions were studied in association with 11 pig blood group systems, (A, B, C, D, E, F,G, H, J, K and L) in matings segregating for blood types and analyzed by using segregation ratios as well as by the least-squares method. Effects of sire, litter size and selection for high whole-body potassium per unit weight of boars on sex ratios were all considered. A total of 1,328 litters of pigs over seven generations in five breed classes (Duroc, Duroc selected, Yorkshire, Yorkshire selected and Duroc x Yorkshire crossbred selected classes) were studied.
