Abstract The effects of high dietary levels of fresh or moderately oxidised fish oilon performance and blood parameters in mink females were investigated during the winter,reproduction, and lactation periods. Furthermore, the effects of the diets on kit performance wereinvestigated during the lactation and early growth periods. (more…)

Abstract A study of ewe performance was undertaken in 795 sheep flocks based on datafrom the Norwegian Sheep Recording System. Herd level data included in the annual report for 1998were used as the basis for the study Average flock size was 75.3 ewes. The material was consideredas representative of the better and more motivated sheep farmers in the mountain valley regions insouth-eastern Norway. (more…)

Abstract The size and composition of the nematode assemblage in soil under faecal patsderived from young cattle treated or untreated with either ivermectin sustained-release boluses, orthe nematophagous fungus Duddingtonia flagrans , were studied in each of three years. Soil samplestaken 4, 6, 8 and 10 weeks after four deposition dates in 1998 showed significant temporal effectsin many taxa and treatment effects in a few genera. (more…)

Abstract In Denmark, organic feeding is typically based on homegrown feed with a highproportion of roughage. Which crop to grow and use as supplementary feed is investigated in thispaper. In three experiments, barley (B) was compared with another type of supplementary feed: aconcentrate mixture (C), (more…)

Abstract This study was the first to analyze the polymorphic characteristics of a widerange of genetic markers in three Lithuanian horse breeds. Genetic variation at seven red bloodcell alloantigen (blood group) loci, 10 biochemical genetic loci and 16 microsatellites wasexaminated in 31 Zemaitukai, (more…)

Abstract Unlike most domestic livestock species, sheep are widely known as animalswith marked seasonality of breeding activity. The annual cycle of the daily photoperiod has beenidentified as the determinant factor of this phenomenon, while environmental temperature,nutritional status and social interactions may modulate it. The aim of this paper is to review thecurrent state of knowledge of reproductive seasonality in sheep. (more…)
