| Popis: | Plant oils or oil-rich seeds that are rich in unsaturated fatty acids can be used as feedstocks to modify milk fatty acid profiles. The effect of providing lactating Nubian goats with flaxseed oil or crushed seeds on the feed intake, digestion, ruminal fermentation, lactational performance and milk fatty acid profile was assessed. Fifteen lactating does, weighing 33.2 ± 0.8 kg after parturition, were randomly assigned to three treatments in a quintuplicated 3 × 3 Latin square design. Does were stratified according to their previous milk production, parity and expected average milk yield in a 90-day experiment. Does were fed a basal diet containing 500 g of berseem clover and 500 g of concentrates (Control treatment) or the control diet supplemented with 50 g of crushed flaxseed containing 37.5% oil (Seed treatment) or 20 mL of flaxseed oil (Oil treatment). Without affecting the feed intake, crushed flaxseed and flaxseed oil increased (P |
