Description:	Abstract: The present study explored the combined effects of CC (Opuntia stricta [Haw.] Haw.) and full-fat corn germ (FFCG) as a source of supplementary PUFA on milk fatty acid (FA) composition of dairy goats fed elephant grass (EG). Twelve Saanen goats were used in a replicated 4 × 4 Latin square design in a 2 × 2 factorial arrangement of treatments (GC or FFCG as energy sources, and the inclusion or not of CC in the diet as a partial substitute for EG). The proportions of various milk FAs were influenced by CC, FFCG, or both. Significant interactions between CC and FFCG were noted for most trans-C18:1 and CLA isomers. Specifically, including CC in the FFCG-supplemented diet increased the levels of trans-11 C18:1 and cis-9, trans-11 CLA in milk fat, whereas these isomers were unchanged or slightly reduced with CC in the GC diet. Similar patterns were observed for C18:2 n-6, while C16:0 increased with CC in the GC diet. Ratios of trans-C18:1/C18:0 and trans-11 C18:1/C18:0 were notably higher when CC was included in the FFCG-supplemented diet. These findings suggest that CC inhibits the last step of rumen biohydrogenation in dairy goats, enriching milk with trans-11 C18:1 and cis-9, trans-11 CLA when supplementary PUFA is provided in the diet.
