Conjugated linoleic acid (CLA) is recognized as a bioactive compound with significant health-promoting properties. This study aimed to evaluate the potential of palm oil derivatives to enhance milk CLA levels and milk fatty acid quality in Holstein Friesian dairy cows. The study was conducted using a randomized block design (RBD) with four treatments and four replications: (1) Basal ration (Napier grass + concentrate); (2) Basal ration + 2.2% palm-calcium soap (PCS); (3) Basal ration + 2% palm-prilled fat (PPF); and (4) Basal ration + 2% hard palm stearin (HPS). The results showed that palm-prilled fat (PPF) supplementation in the dairy cow significantly improved (p < 0.05) milk fatty acid profile (C18:1-cis and Conjugated Linoleic Acid) and decreased (p < 0.05) ΣtFA in milk. Palm-prilled fat supplementation significantly increased (p < 0.05) the C14:1 and C18:1 desaturase index (DI) and enhanced the health-promoting index (HPI) in milk. Based on this study, it can be concluded that supplementation with PPF was able to enhance milk quality. Furthermore, dietary fat supplementation led to an improved milk fatty acid profile, which may increase its value as a functional food and promote human health.
