Abstract
The
influence of genotype (Cambodian Kondol and Kondol x Duroc) on performance
traits and digestibility indices was studied in eight piglets (average
initial weight, 10 kg) during 28 days. Feed consumption of a simple diet
consisting of wheat bran and fresh water dry fish (9:1 in dry basis) was
ad libitum.
Daily
feed intake and gain were not significantly influenced by the genotype (Kondol
0.94 kg DM and 292 g; KondolxDuroc 1.02 kg DM and 294 g).
There
were no significant effect of treatment (P>0.05) on digestibility of
DM, organic matter and N as estimated by the indirect method (Kondol 76.9,
83.4 and 75.8% respectively; KondolxDuroc 74.8, 83.2 and 76.6%
respectively). There were no evident correspondence amongst digestibility
indices and performance traits of the animals, probably due to the short
length of the trial.
Low
voluntary feed intake and rate of growth in Kondol pigs could be
understood from the point of view that this genotype has never been
improved either by selection or crossing. The use of the indirect method
for estimating total digestibility of nutrients proved to be highly
appropriated in on station conditions of performance tests. This method
can also be employed on farm and then, can be extended to rural areas,
where simple and readily approaches to the nutritive value of non
conventional feeds are of a high priority. Key words: pigs, Kondol, digestibility, performance traits |
