6. Effects of cow-calf contact on feed intake, milk production and energy balance in dairy cows in early lactation
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : The objective of this study was to compare the production level, feed intake and energy balance in early lactation of non-suckled cows against cows in a cow-driven cow-calf contact (CCC) system. CCC systems have become interesting to evaluate as they are thought to provide a more natural behaviour for both the cow and calf, several studies have reported higher growth and better health in calves kept in these systems.

7. Effects of weaning and two separation strategies on cow-calf pairs kept together in an automatic milking system until calves were four months old
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : In the commercial dairy industry calves and cows are usually separated within 24 hours, however there is an increasing interest from the consumers to accommodate dairy cows and their calves together to improve animal welfare. Previous studies conclude that with later separation comes an increase in both calves and cows’ behavioral stress response after separation, however late separation has positive effects on the health and behavior of calves and cows.

8. LED belysning till mjölkkor : jämförelse av olika våglängder
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : Syftet med detta examensarbete var att undersöka om mjölkmängd, foderintag, me-latonin, IGF-1 (Insulin-like growth factor 1) eller aktivitet kan påverkas hos mjölkkor som exponeras för olika våglängder på ljus. Fyra olika ljusbehandlingar jämfördes med varandra vid baslinjen och vid LED. LÄS MER
9. The effects of floor system on production in automatic milking systems
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : Based on the results of a previous Master's thesis, the hypothesis was that farms with slatted floors have lower milk production, both per milking unit and per cow, than farms with solid floors in automatic milking systems. A survey with questions about the farm, the flooring system, cleaning and claw trimming routines was sent to 123 farmers with DeLaval's VMS and additional farmers with DeLaval VMS were invited to the survey via social media.

10. Cow traffic in an automatic milking rotary system : with or without parallel guiding of cows for milking
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : Automatic milking systems and automatic milking rotary systems (AMR) where the cows are gathered and held in a waiting area prior to milking are dependent on cows to enter the milking unit voluntarily. A low rate of cows that voluntarily enter the milking unit affects both the economy, working safety and cow health negatively. LÄS MER
