| Two trials were conducted to examine the effect of chicory included in or as additional plots of the ryegrass–white clover pastures on growth, naturally acquired nematode infections and selectivity of chicory by lambs. In Experiment 1, 31 weaned Texel lambs (36±7 kg) grazed either ryegrass–white clover (CTRL) or ryegrass–white clover–hicory pastures (CHIC). In Experiment 2, 30 weaned Shropshire lambs (32±7 kg) grazed either ryegrass–white clover (CTRL) or ryegrass–white clover with access to small additional chicory plots, which corresponded to 3% (CHIC-LO) or 6% of the total grazing area (CHIC-HI). No consistent differences in live weight gain and nematode faecal egg counts were observed in lambs grazing the different pasture types. Sward height on the... |

| Sammendrag Baggrund og formål Foreliggende rapport belyser økologisk oksekødsproduktion baseret på tyrekalve fra malkekvægsbedrifter og består dels af en analyse af interview og spørgeskemaundersøgelse blandt økologiske landmænd og dels af et litteraturstudie og modelberegninger. Tyrekalve fra økologiske malkekvægsbedrifter sælges ofte til konventionelle bedrifter, men indtil nu har der ikke foreligget konkrete data om, hvor mange og hvorfor økologiske tyrekalve sælges. Salget af økologiske tyrekalve kan anses som et etisk problem, idet økologisk jordbrug skal tilstræbe en produktion baseret på et helhedssyn. Det overordnede formål med rapporten er, at bidrage med viden omkring økologisk oksekødsproduktion baseret på tyrekalve samt at belyse faktorer,... |

| Traditional perennial ryegrass-white clover mixtures have limitations in combined productivity and quality that herbs like chicory may alleviate. This study examined the consequences on productivity and quality of as well as competition and facilitation after introducing chicory into varies ryegrass-legume-based pastures in a field study over 3 consecutive growing seasons. A cultivar of chicory, suitable for grazing, in pure stand was found to out-yield a pure stand ryegrass in terms of dry matter and nitrogen (N) accumulation but was found to yield similar to mixture of chicory and ryegrass. The inclusion of chicory, increased N accumulation per area unit irrespective of associated leguminous species but had no effect (P>0.05) on the combined dry... |
