The effect of grazing management and camelina seed supplementation in the diet on milk performance and milk fatty acid composition of dairy ewes – D. Mierlita, S. Daraban, F. Lup, and A. Chereji – Journal of Food, Agriculture and Environment – 2011

Summary: The objective of this study was to investigate the effects of ewes’ feeding system (grazing vs. part-time grazing) in combination or not with camelina seed (Camelina sativa L.) as dietary supplement on milk yield parameters, and especially on the fatty acid (FA) profile of milk fat. Feeding a grazing diet combined with camelina seed increased the proportion of C18:1, trans-11 FA, of C18:3 and of cis-9, trans-11 conjugated linoleic acid in milk fat at the expense of saturated fatty acids, being considered beneficial to human health. The conclusion was that when the quality and availability of pasture does not limit milk yield, limiting grazing time adversely affects FA profile in milk, with no positive effect on milk yield. Link:
