Effects of mountain grassland maturity stage and grazing management on carotenoids in sward and cow's milk

2006

Carotenoids are involved in the sensorial and nutritional values of dairy products. In grazing systems, both herbage maturity stage and grazing management may affect the amount of carotenoid ingested, thus these factors may affect carotenoid concentrations in milk. Two homogenous plots of mountain grassland (1.4 and 2.0 ha) were grazed during two cycles of growth by 6 dairy cows in mid lactation, in strip (SG) and rotational grazing (RG), respectively. We monitored the changes in carotenoid concentrations in sward and milk, measured by HPLC twice a week. Seven carotenoids were identified in the sward: violaxanthin, antheraxanthin, epilutein, lutein, zeaxanthin, ß-carotene and 13-cis ß-carot…

Environmental Management Maturity: The Role of Dynamic Validation.

2021

Maturity models enhance the performance of companies by prescribing a trajectory through stages of increasing capability. However, a recent review of maturity models concludes that current maturity models hardly meet the design principles required for prescriptive use. To address this deficiency, we conducted semistructured interviews and a Group Model Building study with industrial companies in Spain in which we studied the progression toward a Leading Green Company as the highest maturity stage of environmental management. The findings from the study were tested using surveys with enterprises in Spain, Italy, and the United Kingdom, semistructured interviews in the United Kingdom and case…

The maturity stage of the grass affects milk fatty acids of cows grazing a mountain grassland

2010

International audience; We aimed to quantify the effect of the growth stage of a mountain grassland pasture on the fatty acid (FA) composition of grass and milk. In June (growth) and October (regrowth), a mountain pasture was continuously grazed by six dairy cows in a strip grazing system. During June, the grass C18:3n-3 content decreased while C16:0, c9-C18:1 and C18:2n-6 content increased. During October, the grass FA composition was similar to that observed in the first part of June. During June, milk saturated FA (SFA) content increased while the sum of the trans FA and polyunsaturated FA (PUFA) content decreased, mainly due to the decrease in C18:3n-3 and c9t11-CLA percentages. At the …

Influence of Variety and Maturity Stage on Sterolic Composition of Virgin Olive Oil from Central-Western Sicily

Olive oil is one of the most important food products throughout the Mediterranean Basin due to its high nutritional and dietetic value. In recent years, there has been increased interest in the sterols of olive oil for their health benefts and their importance to virgin olive oil quality regulation. The impact of sterols on the human health is proved by several studies, showing that a suffcient quantity of β-sitosterol inhibits the intestinal absorption of LDL-cholesterol. In olive oil the phytosterol concentration ranges from 800 to 2600 mg kg-1. Sterol esters evaluation has been proposed as useful parameter in studies related to varietal and geographical discrimination. Cultivar and matur…
