“ Copper supplementation increased backfat depth, IMF, and percentage of polyunsaturated fatty acids in LM and decreased LMA in the carcass of JYB goats.”
“Dietary Cu supplementation increased the percentage of C14:0 (P < 0.01), C20:4 (P < 0.01), and total polyunsaturated fatty acids (P = 0.03), decreased C18:1 trans (P = 0.04), and tended to decrease C18:0 (P = 0.08) in LM.”
“In particular, the analysis showed that Cu had a significant negative effect on the polyunsaturated PLFA, linoleic acid (18:2omega6,9), which has previously been reported to correlate positively (R2 = 0.92) with freeze tolerance in D. octaedra.”
“Cu was more toxic for fatty acids than Cd (even at 1 μM); mainly, PUFA levels strongly decreased (from 43% of total acids in control to 28.9% and 5.4% at 1 and 10 μM Cu treatment, respectively).”
