Effect of n-3 unsaturated fatty acids supplementation on milk yield of dairy goats

The aim of this research study was to determine the effect of n-3 unsaturated fatty acids (α- linoleic, eicosapentaenoic and docosahexaenoic) supplementation on milk yield of dairy goats. Furthermore, the persistence of this effect after the supplementation period was analysed. The research was conducted on dairy goats (Alpine and Saanen) bred at an indoor farm. Regarding the experimental period, the measurements of milk yield at milking (morning and evening) was performed in the period before supplementation (BS), during supplementation (S), and after supplementation (AS). Regarding the added supplement, animals were randomly allocated into control group (G- 4) with no added supplement and test groups (G- 1 ; G-2 ; G-3) where a supplement containing PUFA was added over a period of five days. Based on the obtained results, it could be concluded that the addition of PUFA in goats’ ration alters the milk production. The supplementation of docosahexaenoic and eicosapentaenoic acid in goats’ ration gives rise to a positive energy balance resulting in increase of daily milk production. Furthermore, in case of docosahexaenoic acid, these effect continued also in the period after supplementation.
