The data was analysed using SAS v9.1 (SAS Institute Inc. Cary, NC).
The differences between the crosses were studied by the method of
least squares using the General Linear Model (GLM) procedure. Partial
correlation coefficient was calculated to study the relationship
of the birth weight and cross-sectional area of muscle fibres. The
effect of crossbreed was adjusted for.
To study the possibility of identifying pigs from different crosses
that resemble each other on the basis of the studied properties, the
pigs were classified using discriminate analysis. Each property was
studied separately.
