Effect of feeding regimen on the fatty acid profile of sheep bulk tank milk
[EN]The quality of dairy products is affected by the fatty acid (FA) profile of the milk. The aim of this study was to determine whether the feeding regimen and lactation stage of the sheep produced a healthier FA profile of milk. The study was carried out on 30 commercial farms, and the feeding reg...

| Sumario: | [EN]The quality of dairy products is affected by the fatty acid (FA) profile of the milk. The aim of this study was to determine whether the feeding regimen and lactation stage of the sheep produced a healthier FA profile of milk. The study was carried out on 30 commercial farms, and the feeding regimens studied were different grazing allowances (50%, G1; 25%, G2; 0%, G3). The variance explained by the lactation stage for the FAs was below 4.18%. The milk from the grazing allowance G1 (50% grazing time per day plus alfalfa silage and barley grains) showed a higher conjugated linoleic acid (1.16%) proportion, followed by the grazing allowances G2 (0.90%) and G3 (0.79%), which showed that grazing improved the nutritional quality of milk fat. |
