5. Conclusions
Feeding high levels of PKC and DC to growing goats improved feed intake but reduced daily gain and carcass quality. The proportion fat in the carcass and LD muscle was increased by inclusion of DC, PKC, and PO, probably because of higher fat intake. The excretion of N shifted from urine to feces as a result of feeding DC and PKC. It appears, therefore, that high dietary levels of DC or PKC (80% of DM) might have an adverse effect on growth performance and carcass quality in goats.
