IN VITRO EVALUATION OF CONCENTRATE FEED CONTAINING Indigofera zollingeriana IN GOAT
Abstract: This study was
conducted to evaluate the fermentability and nutrient digestibility of concentrate
feed containing Indigofera zollingeriana using in vitro technique. Randomized
complete block design was used on 3 types of concentrate feed and 4 groups
(replicates) of goat's rumen liquid. The concentrate feeds were R1, R2 and R3
containing I. zollingeriana at 0 (control), 20 and 40%, respectively. Variables
observed were total gas production, in vitro dry matter digestibility (IVDMD),
organic matter (IVDOM), and crude protein (IVDCP), volatile fatty acid (VFA)
profiles and NH3 concentration. Data were analyzed using analysis of variance
(ANOVA). Results showed that there was no significant effect of R3 on IVDMD,
IVDOM and IVDCP as compared to R1 and R2. However, there was significant
difference (P<0.05) of the parameters between R1 and R2 (P<0.05). There
was no significant effect (P<0.05) of different Indigofera levels on total
gas production. The partial VFA of each concentrate feeds was not significantly
different, but the percentage of acetic acids of concentrates containing I.
zollingeriana were higher than those of control (P<0.05). The concentration
of rumen NH3 of R2 was lower than R1 and R3 (P<0.05) even though the IVCPD
of R2 was higher than R1. It could be concluded that the inclusion of I.
zollingeriana as concentrate feed ingredient at 20% maximum level .
