A. Rojas et al., FATTY-ACID COMPOSITION OF VERATA GOAT KIDS FED EITHER GOAT MILK OR COMMERCIAL MILK REPLACER, Small ruminant research, 14(1), 1994, pp. 61-66
Fatty acid composition of perirenal fat of young Verata male and femal
e kids fed with natural milk and with three concentrations of commerci
al milk replacer was studied. There was no effect associated with sex.
In each gender the only statistical difference in fatty acid composit
ion between the four feeding groups under study were pentadecanoic aci
d (C15:0), heptadecanoic acid (C17:0) and heptadecenoic acid (C17:1) w
hich were higher in all cases in naturally fed kids (P < 0.05). The or
igin of odd-numbered fatty acids in depot fats of goat kids is discuss
ed considering the possible role of microbial rumen synthesis in goat
kids or the direct incorporation from the milk (or milk replacer) fat.
The relatively low stearic concentration in perirenal fat in all grou
ps (around 15%) suggest low ruminal activity. Determination of C15:0,
C17:0 and C17:1 in perirenal fat could help differentiate the feeding
system of young kids and might be useful for identification purposes o
f goat kid carcasses.
