  1. 11. Time budgets of dairy cows in cow-calf contact system with automatic milking

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Teresa Johansson; [2021]
    Keywords : Dairy cows; Time budget; AMS; Cow-calf contact;

    Abstract : Time budgets of dairy cattle are useful to determine the amount of time the cows can allocate to all the behaviours throughout the day. In an automatic milking system (AMS), time budgets are of interest as the individuals are able to choose how to spend the majority of their time, besides the time in the milking robot, and can be used to ensure adequate amounts of time are spent on essential behaviours, such as lying and eating.

  3. 12. Bättre sårläkning hos kalvar som hålls med sin mamma? : sårläkning och salivkortisol efter avhorning av mjölkraskalvar med lång diperiod

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Rebecka Lindqvist; [2021]
    Keywords : avhorning; sårläkning; salivkortisol; nötkreatur; inhysning; social grupp;

    Abstract : Ett flertal studier indikerar på ett samband mellan social interaktion och snabbare sårläkning hos olika djurslag. Social support kan även sänka kortisolnivåer i samband med en stressad situation. Fysisk kontakt mellan ko och kalv kan därför potentiellt bidra till bättre sårläkning och lägre kortisolnivåer hos kalven efter avhorning. READ MORE

  4. 13. Effects of cow-calf contact on feed intake, milk production and energy balance in dairy cows in early lactation

    Abstract : 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.
