This study evaluated the effects of different dietary n-6/n-3 polyunsaturated fatty acid (PUFA) ratios on in vitro ruminant fermentation. Methane production, composition, and microbial profiles were compared after fermentation rumen fluid collected from cows that had been fed isoenergetic isoproteic experimental diets at three ratios: 3.04 (HN6, high n-6 source), 2.03 (MN6, medium 0.8 (LN6, low...

The potential to modify the milk fatty acid (FA) composition by changing the cow or goat diets is reviewed. Ruminal biohydrogenation (RBH), combined with mammary lipogenic and D-9 desaturation pathways, considerably modifies the profile of dietary FA and thus milk composition. The pasture has major effects by decreasing saturated FA and increasing FA considered as favorable for human health (c9...

Soybean oil is a high source of unsaturated fatty acids which if given to sheep have the potential accumulate in meat. However, rumen undergoes biohydrogenation by microbes, and addition fat feed has reduce fiber fermentation can an impact on animal performance. This study aimed determine effect combination protected non-protected soybean supplementation characteristics fermentation, nutrient d...

ABSTRACT Beef composition are directly influenced by the dietary fat, particularly in ruminants, due to rumen biohydrogenation, which promotes alterations fatty acid (FA) profile and affects meat quality. sensorial, chemical, FA compositions of intramuscular subcutaneous fat were evaluated, from 40 Nellore males finished on feedlot diet based, containing cottonseed (CSB) soybean by-product (SOB...
