| I det økologiske husdyrhold skal dyrene have adgang til grovfoder. Grovfoderet skal ikke udgøre en bestemt andel af foderet, men være dagligt tilgængeligt for alle dyr. Grovfoderet tilfredsstiller dyrenes adfærdsmæssige behov mht. mæthed og rodeadfærd, og formodes at have en gavnlig virkning på deres sundhedstilstand. Ønsket om en øget økologisk svineproduktion påvirker økosystemets næringsstofbalance, hvorfor det er vigtigt at kende til svinenes bidrag hertil. Der er ikke særlig megen viden om, hvor godt svin udnytter grovfoder, fordi forskningen i mange år har været fokuseret på koncentrerede fodermidler, der giver maksimal foderudnyttelse og vækst. I projektet, som beskrives i det følgende, er der lavet nogle basale undersøgelser af, hvordan... |

| The present investigation aimed to study the ileal and fecal digestibility of three forages (Clover grass, Clover grass silage and Pea-Barley silage) supplemented to a basal diet. A total of 24 pigs, adapted to eating forages by supplementing a basal feed with clover grass silage from weaning, were fitted with a T-cannula at the terminal ileum at approximate 30 kg LW. For each of the three types of forage, two balance trials with 4 weeks interval were carried out. Two pigs in each test were fed the basal diet while 6 others were fed the basal diet plus forage throughout the whole experiment. The intake of forages was relative low and quite variable and accounted on average for only 10-12 % of the daily dry matter intake. Ileal digestibility estimated by... |

| The present investigatin was undertaken to study the faecal degestibility of dry matter organic matter, protein and fibre for growing pigs fed on high level roughage. The three roughage types studied were clovergrass, clovergrass silage and wholecrop pea-barley silage. The study was conducted in two experimental periods (exp 1 and exp 2). Ineach experiment 10 crossbred female pigs (5 x 2 littermates) were diveded into two groups fed either fresh clovergrass or frozen and thawed clovergrass (exp 1) and either clovergrass silage or wholecrop pea-barley silage (exp 2). |

| In 2 experiments, 10 gilts (30 kg initial liveweight) were given a basal diet with fresh or frozen/thawed clover-grass, clover-grass silage or whole-crop pea-barley silage. The faecal digestibility of gross energy (GE), DM, organic matter (OM), dietary fibre (DF) and CP were measured. The 3 roughages, leaves and stems of clover-grass and the basal diets were also tested for in vitro OM digestibility. Roughage intake was similar in both experiments and the average proportion of roughage ingested was 18-19% of DM. There were no differences between fresh and frozen/thawed clover-grass nutrient digestibility values. Glucose (cellulose) and xylose were the main constituents of the non-starch polysaccharides (NSP) in the roughages, with whole-crop pea-barley... |
