A grazing experiment was undertaken to evaluate the effect of PEG supplementation on the
fatty acid composition of milk from Sarda sheep grazing sulla. Twenty-four late-lactating
sheep (12 per group), were paired and split into two groups: group control (CON), dosed
daily with a quenching gun with 200 ml of water, and group PEG, dosed with 200 ml of a
50/50 w/v water solution of PEG. The sheep grazed two 0.8 ha plots of sulla under a
rotational grazing scheme. The contents of c-9, t-11 CLA and t-11 C18: 1 in milk fat were on …

The concentration of condensed tannins (CT) in sulla (Hedysarum coronarium L.) is
moderate and overall regarded as beneficial. However, the intake of this forage can reduce
diet digestibility, particularly during flowering phase. An experiment was run to assess the
effect of CT on feeding behaviour, intake, diet digestibility and performance of dairy sheep
rotationally grazing sulla at flowering phase. Twenty-four late-lactating sheep were blocked
in two homogeneous groups and submitted to the following treatments: i) twice daily …
