of Large White (LW) and Nigerian Indigenous (NI) pigs was carried out
using 9 NI (1 boar and 8 gilts) and 7 LW (2 boars and 5 gilts). Their
progenies comprising 20 LW (10 boars and 10 gilts), 22 NI (12 males and
10 females) and 9 LWxNI crossbred pigs (3 males and 6 females) were used
to compare the hematological attributes at 9, 17 and 25 weeks of age.
The three breeds were managed in a similar fashion. It was observed that
heat was virtually silent among the NI gilts and intra breed sexual congresses
were more effective than the interbreed congresses. The LW pigs had significantly
higher (p<0.05) birth weight than the NI pigs (1.3 kg versus 0.8 kg)
and had longer gestation period (116.0 days versus 111.7 days) but litter
sizes were similar. No significant age or breed differences were found
in haematological parameters (p>0.05) and the values were within the
normal ranges generally accepted as reference values for healthy pigs.]]>Adebambo, O.A. and A.E.
