| The aim of this field study was to investigate interactions between gastro-intestinal nematode (GIN) infection, milk performance and age in goats in order to identify animal groups with higher susceptibility to GIN. On 3 farms (farm A: n = 29, farm B: n = 33, farm C: n = 117 milking goats) fecal egg count reduction tests (FECRT) were performed in summer. All 179 milking goats were enrolled in FECRT and individual milk performance was recorded before and after FEC for FECRT. Furthermore, in early summer and autumn bulk fecal samples were cultured for every farm and GIN genera were determined. |

| In Australia and New Zealand the formulation of breeding values for GIN resistance led to large selection programs in sheep successfully improving genetic resistance to GIN. Compared to sheep, the progress with respect to breeding for GIN resistance for various reasons has been much slower in goats. Data on heritabilities of potential auxiliary traits for selection and knowledge about their genetic correlation to production traits is limited. The present Swiss study was designed to fill this gap. A total of 1.500 goats (20 flocks) of the Alpine and Saanen breed were enrolled in the study. They were individually phenotyped twice for faecal egg count (FEC), FEC of Haemonchus (HCFEC; using fluorescin based differentiation of eggs), FAMACHA eye scores and... |
