Abstract:

This study was aimed to investigate the effect of sampling position, gender and feeding time on fatty acid
composition of Rex rabbit meat. Six 90-day-old and six 150-day-old (half male and half female) French Rex rabbits were
selected randomly and the fatty acid composition and lipid content of leg muscle and dorsal muscle in these samples were
analyzed. The results revealed significant differences in the total intramuscular lipid content between both genders and
between two feeding times (P < 0.05), which might be mainly attributed to the content of triglyceride (P < 0.05). A
significant difference was observed for total fatty acid composition between both genders and between two feeding times
(P < 0.05) and this marked difference between two feeding times might be related to its intramuscular triglyceride content.
However, the difference between two genders might be caused by the differences in both triglycerides and phospholipids.
Therefore among these three factors studied in this paper, gender made the biggest contributions to fatty acid composition of
French Rex rabbits, followed by feeding time, and sampling position showed the least effect.

Key words: Rex rabbit, position, gender, feeding time, fatty acid composition
