ABSTRACT
The study investigated the effect of breed of
sire on growth characteristics of exotic crossbred pigs in a humid tropical
environment. Body weight and other body traits, namely body length {BL), height
at withers (HTW), heart girth (HG) and rear girth (RG) were measured biweekly
for three months (12 weeks) on 96 crossbred progeny of twelve Large White (LW)
sows mated with three different breeds of sire, namely Large White, Hampshire
(HS) and Duroc (DC) in the ratio of 1:4. The data were analyzed with Analysis
of Variance appropriate for Completely Randomized Design (C.R.D.) and
significant means were separated with Duncan's New Multiple Range Test (DNMRT).
There were significant (P<0.05) differences among the breeds of sire for BW,
HG and RG at different ages. HS- sired progeny were superior
to the progeny of the other breeds for most of the traits measured post
weaning. The analysis shows that during preweaning phase, HS - sired progeny
were superior in 48%, LW - sired progeny were superior in 40% and DC- sired in
12% in all the traits measured. HSsired progeny were superior in 70% of all
traits, while those of LW sires showed superiority in only 30% of the traits in
the post-weaning phase. Toe Hampshire breed is recommended as the preferred sire breed
for crossbreeding purposes to bring about genetic improvement in growth of pigs
in a humid tropical environment. Regressions (R? ) of body weights on linear
body measurement were all very highly significant (P<0.001) except at 70
days where R was poor (10.5%). The determined prediction equation shows that BL
and RG could be effectively used to predict body weight of pigs.
