| Summary: | Rice straw is seldom used as goat feed despite
reports of higher intake and digestibility of poor
quality roughage by this species . Studies were conducted
to evaluate local rice straw , define its limitation and
investigate means to improve its utilization by goats.
Compositional and degradability studies showed that
untreated rice straw is deficient in N and several
minerals and is poorly degraded . Calcium hydroxide and
sodium hydroxide treatment increased degradability but
the treated material was less acceptable to goats
compared to rice straw treated with urea or ammonium
hydroxide which has relatively lower degradability.
Treatment with nitric acid removed all the hemicellulose
and was totally unacceptable to goats.
The ad libitum intake and in vivo digestibility of
urea-treated straw was higher than that of urea
supplemented straw and untreated straw . |
