Abstract |
We have earlier shown that sun dried, ground, non-heated cassava chips
are highly digestible in growing pigs. In this study, we tested the
possibility that sun dried cassava meal would also be well digested by
dogs. Twelve adult dogs were subjected to a 3×3 Latin square design with
three experimental diets and three periods (three weeks each). The
control diet was a homogenized, commercial, extruded diet that was
pelleted at environmental temperature. The two test diets were made in
the same manner, but after grinding, the commercial diet was blended
with either 10 or 30% of sundried, non-heated cassava meal. The diets
were well accepted by the dogs. The inclusion of cassava in the diet did
not affect the amount and water content of faeces, but it significantly
elevated the faecal score in a dose-dependent fashion. The faecal score
for the 30% cassava diet was equivalent to diarrhoea. It was suggested
that the feeding high amounts of non-heated cassava lowers water binding
of faecal matter. The apparent digestibility of the non-structural
carbohydrates (nitrogen-free extract) in non-heated cassava, as
calculated by the difference method, was found to be 79.8% for the 10%
cassava level and 84.0% for the 30% level. It was concluded that high
intake levels of sun dried, non-heated cassava are unsuitable for dogs.
