Using safflower supplementation to improve the fatty acid profile in milk of dairy goat
2015
Abstract Although supplementation effects of safflower seed oil (SSO) on dairy cattle have been extensively studied, little information exists on the effective use of SSO in lactating dairy goat. Thus, this study investigated the effects of SSO supplementation on feed intake, yield, composition and fatty acid profile of milk of lactating dairy goat. Fifteen multiparous Xinong Saanen dairy goats (63 ± 2 DIM) were assigned to a 3 × 3 Latin square for periods of 21-d. They were randomly allocated to three treatments: (A) unsupplemented (control), (B) supplemented with 10 g SSO (low dose, SSO-1), and (C) supplemented with 30 g SSO (high dose, SSO-2) per kilogram diet dry matter (DM) of total ration. Feeding SSO resulted in a significant increase of DM intake compared with the control ( P P P P 16) in milk fat. Furthermore, SSO supplementation increased cis -9, trans -11 CLA contents from 0.49 g/day of the control to 0.68 and 1.18 g/day for SSO-1 and SSO-2, respectively ( P
