The major finding from this study is that addition of WCS to the diet of lactating dairy cows resulted in a persistent reduction in CH4 emissions (g of CH4/kg of DMI) over a 12-wk period and that these reductions in CH4 are consistent with previous work that has studied the addition of oilseeds to ruminant diets.

This effect, recorded in a 2-year randomised trial carried out in healthy, elderly men and women studied together, remains to be mechanistically explained since it was observed, as in the two above-mentioned studies, in the absence of any persistent reduction in bone resorption markers.
When the same objects were shifted anew to a novel configuration, a significant persistent reduction in synaptic efficacy was once more observed (ANOVA, F1,593 = 223.48, P < 0.0001; n = 14), which was not significantly different from the change observed during novelty exploration (ANOVA, F1,587 = 2.5229, P = 0.11274; n = 14).
