Blood parameters of lambs fed diets with vegetable oil supplements.

摘要

The effect of different types of dietary fat on rumen parameters was assessed in 4 lambs with rumen cannulae in a 4x4 Latin square design. The basic ration for the control group consisting of meadow hay and concentrate (40:60) was supplemented for the experimental groups with 5% of rapeseed, sunflower or linseed oils. Volatile fatty acids, ammonia concentration and pH in rumen fluid, as well as glucose, free fatty acids, cholesterol and triglycerides [triacylglycerols] in blood were determined. The propionic acid level was lower (P<0.05) in the rumen fluid when 5% of rapeseed oil was added to the ration. Addition of rapeseed oil or linseed oil decreased the blood glucose level.
