- Pomegranate seed oil (PSO) and linseed oil (LSO) in lactating goat's diet.
- PSO and LSO inclusion in diet did not affect goat's dairy performance.
- PSO increased total antioxidant capacity (TAC), but LSO decreased TAC of milk.
- Dietary PSO increased total polyphenols and decreased somatic cell count in milk.
Twenty-four Mahabadi goats (DIMÂ =Â 45Â Â±Â 6 d, BWÂ =Â 38.4Â Â±Â 3.8Â kg, average daily milk yieldÂ =Â 1.05Â Â±Â 0.14Â kg) were used in a completely randomized design experiment for 42Â days to evaluate the effects of pomegranate seed oil and linseed oil on their performance, blood metabolites and antioxidant status. Experimental diets were: 1- control diet (basal diet without added oil, COND), 2- basal diet with 25Â g/kg DM pomegranate seed oil (PSOD) and 3- basal diet with 25Â g/kg DM linseed oil (LSOD). Dry matter intake (DMI), milk yield, milk protein, milk lactose, ADG and production efficiency in dietary treatments were similar in different groups (PÂ >Â 0.05), but milk fat increased by addition of linseed and pomegranate seed oils to diet (PÂ <Â 0.05). Blood metabolites (glucose, total cholesterol, triglyceride, LDH and LDL) were not affected by dietary treatments (PÂ >Â 0.05). Relative to the COND, PSOD increased total antioxidant capacity (TAC), whereas LSOD decreased TAC of milk and blood (PÂ <Â 0.05). In contrast, compared with the COND, milk and blood malondialdehyde (MDA) content decreased in goats fed PSOD, whereas LSOD increased MDA content of milk and plasma (PÂ <Â 0.001). Also, milk somatic cell count decreased with PSOD compared with COND and LSOD (PÂ =Â 0.001). The highest level of milk total polyphenols was found in goats fed PSOD (PÂ <Â 0.0001). Results suggest that it is possible to improve antioxidant status and milk fat of dairy goats by feeding pomegranate seed oil (25Â g/kg DM) as a natural antioxidants.
