| evaluation of long-chain alcohols as diet composition markers in goats grazing heathland areas. | an experiment was conducted to assess the potential of long-chain alcohols (lcoh), in alternative or combined with alkanes and long-chain fatty acids (lcfa), as faecal markers to estimate the diet composition of goats grazing heathland vegetation with associated improved pastures. a total of seven diets were offered across the grazing season. the diets were composed of mixtures of herb species (lolium perenne and trifolium repens) and woody species (erica spp., calluna vulgaris and ulex gallii) ... | 2012 | 22436286 |
| arthropod fauna on grassland-heathland associations under different grazing managements with domestic ruminants. | the effects of two grazer species (cattle or sheep) and two flock types (single or mixed with goats) on vegetation and arthropod fauna were studied in a factorial design on eight plots which comprised two thirds of mechanically cleared heathland and one third of improved ryegrass-clover grassland. after six grazing seasons, the shrubland areas were dominated by gorse (ulex gallii) in all treatments. herbaceous cover was higher under mixed than under single grazing, and under sheep than under cat ... | 2010 | 20338541 |
| assessment of very long-chain fatty acids as complementary or alternative natural fecal markers to n-alkanes for estimating diet composition of goats feeding on mixed diets. | this study aimed to assess the use of very long-chain fatty acids (vlcfa) as an alternative or a complement to n-alkane markers for estimation of diet composition of goats fed 7 different diets, composed of different proportions of herbaceous (lolium perenne and trifolium repens) and heathland woody species (erica umbellata, erica cinerea, calluna vulgaris, erica arborea, and ulex gallii), in a metabolism study. diet composition was estimated from vlcfa (i.e., c(22) to c(34)) and alkane (i.e., c ... | 2009 | 19395523 |
| application of long-chain alcohols as faecal markers to estimate diet composition of horses and cattle fed with herbaceous and woody species. | utilization of long-chain alcohols (lcoh) as diet composition markers in horses and cattle was assessed in a study conducted with 12 mature crossbreed mares (385±47 kg bw) and six adult non-lactating cows (499±36 kg bw) of asturiana de los valles breed. the lcoh data were combined with alkane and long-chain fatty acid (lcfa) data to test the applicability of combining these markers to estimate diet composition. animals were randomly divided into groups of three animals and received a daily total ... | 2015 | 26160068 |
