DISCUSSIONCompared to the basal die

DISCUSSION
Compared to the basal diet the best apparent
improvement in the growth performance of goats in the
present experiment was achieved with the dietary
supplement of turmeric powder, while the growth
performance of goats fed the vitamin E supplemented
diet was similar to the goats receiving the basal diet.
This is in agreement with Yang et al. (2002) who
reported no effect of the dietary vitamin E supplement
on the growth performance, carcass weight or fatness of
cattle. Intermuscular fat in the breast and flank cut
decreased in the carcass and the increased depth of the
longissimus muscle due to the vitamin E supplement;
the other indicators of the carcass quality in the present
experiment were similar for the CN and the VE
treatments. Similarly, Eikelenboom et al. (2000)
reported that dietary vitamin E treatment had not
affected the live weight before slaughter, hot carcass
weight and the dressing percentage in goats. Results
of other studies with Boer and Spanish goats
(Mahgoub et al., 2004; Mahgoub and Lu, 1998;
Turner et al., 2005; Wildeus et al., 2007) showed
higher mean dressing percentage than in the present
experiment, but this was probably due to the small
size of the local Kacang goat in comparison with the
meat type Boer or Spanish goats. Others reported the
dressing percentage in the range of 43.9-55.7% in
Boar, South Africa indigenous and Angora goats
(Tshabalalaa et al., 2003; Lupton et al., 2008), which
is similar to that in the present experiment (46.7-49.9
%). Although the goats fed the Andrographis
paniculata powder-supplemented diet produced
significantly better FE than the goats fed the basal diet,
this appeared to be at the expense of decreased feed
intake. The reason for the relatively low feed intake in
the AP treatment is not exactly known, but it could be
related to lower palatability of the AP diet in
comparison with other diets used in the present
experiment. In general, the AP treatment produced
more desirable leaner carcass with higher proportion of
meat and better longissimus muscle cut than the CN
treatment. However, further research is required to
determine the cause of lower feed intake before
Andrographis paniculata powder could be
recommended as a feed additive. The apparent growth performance was better for the turmeric-supplemented
goats than for the control goats and their daily weight
gain of 102 g day-1 was approximately equal to that
reported for Spanish goats (103 g day-1) fed an alfalfa
hay-based diet supplemented with a concentrate at
0.5% of body weight (Turner et al., 2005). The above
gains were better than that of 96 g in the castrated
Angora kids raised in a feedlot system (Lupton et al.,
2008) or 84 g obtained for the present basal diet. In
addition, there was in general more meat in the carcass
with much larger longissimus muscle in the turmeric
supplemented goats than in the control goats in the
present experiment.
