| The fatty acid (FA) profile of ghee produced from milk of cattle–yak hybrids grazing five mountain pasture sites along a high-alpine transhumance route in Nepal was analysed. Pastures differed in altitude above sea level(2600–4500 m), time period of being grazed and phytochemical composition of the swards. Additionally, a comparison of ghee from purebred yak and hybrid was performed, with samples produced at two of the sites. Pasture site had a strong effect on almost all FAs. Proportions of oleic, linoleic and a-linolenic acid in ghee were smallest on the highest pasture at 4500 m where the largest condensed tannin concentrations in the forages were found. No systematic site effects were found for c9,t11 conjugated linoleic acid and total polyunsaturated... |

| The aim of the present research was to study the plant species selected by freeranging cattle in southern Bolivian subtropical mountain forests. The cattle were followed from May to November 2005 during 4-5 days/month in two study sites. The number of bites on the different plant species were recorded every 6 min. during 1 min. of actual observation. Additionally, plant availability was measured. The selection and availability data were ranked, giving rank number 1 to the most frequently selected plant species. Basing on this ranking system, species were categorized into four categories. Overall, 447 plant species were found in the study sites, whereof 364 were observed to be selected by the cattle. A low number of species (15, including... |
