| Popis: | The objective of this experiment was to investigate the effects of dietary pomegranate seed oil and linseed oil on lactational performance, ruminal fermentation parameters, nutrients digestibility and milk fatty acid (FA) content, particularly conjugated linoleic acid (CLA), conjugated linolenic acid (CLnA) and vaccenic acid (VA) of dairy goats. Twenty-four Mahabadi goats in mid lactation were assigned to three dietary treatments: 1- control diet, basal diet without added oil (CON), 2- diet supplemented with 25 g/kg pomegranate seed oil (PSO), and 3- diet supplemented with 25 g/kg linseed oil (LSO), on a dry matter (DM) basis. Feed intake, milk yield and 4% fat-corrected milk yield were similar for goats fed different diets. Milk fat concentration ( P P P >0.05). Addition of vegetable oils to diet had no effect on apparent digestibility of nutrients and ruminal fermentation parameters ( P >0.05). The proportions of VA ( P trans -9+ trans -10, P cis- 9, trans -11 CLA (rumenic acid) increased with oil supplements ( P cis -9, trans -11, cis -13 C18:3 CLnA (punicic acid) in milk fat ( P P P P P |
