Abstract


The objective of this study was to the effect of biological treatments (ZAD, fungus
and ZAD with fungus) on feed intake, digestibility coefficients, nutritive value and
nitrogen balance of rice straw and some rumen liquor and blood parameters.
Twelve adult Ossami rams were divided into four similar groups and used to carried
out four metabolic trials using three animals for each group (all groups were fed the rice
straw ad. Libitum ) the first (11) was the control (untreated rice straw), the second (T2)
was rice straw treated with ZAD, the third (T3) was rice straw treated with fungus
( Pleurotus osteratus ) and the fourth (T4) was rice straw treated with ZAD and fungus.
T2, T3 and T4 increased (P<0.05) crude protein of rice straw and decreased (P<0.05) dry
matter, crude fiber, NFE, NDF, ADF, ADL and cellulose contents than the control
group. Dry matter intake (DMI) increased (P<0.05) in the groups fed rice straw treated
with ZAD, fungus and ZAD+ fungus than the control group. ZAD, fungus and ZAD +
fungus treatments increased (P<0.05) digestibility coefficients of CF, ADF, NDF, ADL,
cellulose and hemicellulose than the untreated rice straw. Total digestible nutrients
(TDN) and digestibility of crude protein (DCP) for T2, T3 and T4 were higher (P<0.05)
than untreated rice straw. The rumen liquor parameters (NH3-N) and TVFA's
concentrations were highest value after 3 hours of feeding in all groups. All of treated
rice straw groups had no significant differences (P<0.05) for urea, total protein, albumin,
globulin, GOT and GPT than untreated rice straw.

Twenty-four Ossimi lambs averages (20.0 ± 0.3 kg) were used in feeding trial lasted
120 days. Feeding trail results showed all biological treatments had higher dry matter
intake (1037, 990, 896 and 786g/d) and average daily gain (169.2, 163.3, 134.3 and
92.5g) for T2, T3, T4 and Tl, respectively. Biological treatments indicated that it they
could be good method to improve the nutritive value of rice straw.
