Measurement of competitiveness in smallholder livestock systems and emerging policy advocacy: An application to Botswana
Publicado 2014“…The results show the presence of inefficiency, with about 74% of the variation in actual profit from maximum profit (profit frontier) between farms mainly arising from differences in farmers’ practices rather than random variability. Further the mean profit efficiency level of 0.58 suggests that there is a substantial scope to improve beef profitability in Botswana. …”

Heterogeneity in the antibody response to foot‐and‐mouth disease primo‐vaccinated calves
Publicado 2018“…Three linear hierarchical mixed regression models, one for each strain, were formulated to assess the heterogeneity in the immune responses to vaccination. The dependent variables were the antibody titres induced against each FMDV strain at 45 dpv, whereas sire's ‘breed’ was included as a fixed effect, ‘sire’ was included as a random effect, and ‘farm’ was considered as a hierarchical factor to account for lack of independence of within herd measurements. …”

Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor
Publicado 2005“…In total, 203 cell-count observations from 14 hoof-diseased and 32 healthy cows were analysed using mixed least-squares multivariable regression modelling. A random effect for cow identity was included. The principal explanatory variable was disease month, coded as -1 the month before diagnosis, as 0 for the same month as diagnosis, as 1 or 2 for the corresponding number of months after diagnosis, and as 3 for 3 months after diagnosis and all observations in healthy cows. …”
