1. 1. 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 Management

   Författare :Carina Tufvesson; [2021]
   Nyckelord :Cow-calf contact system; dairy cow; suckling; feed intake; feeding pattern; milk production; energy balance;

   Sammanfattning : 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.

3. 2. Automatic Body Condition Scoring on Dairy Cows of the Swedish red breed

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

   Författare :Gabriella Eva Foschi Lundmark; [2016]
   Nyckelord :dairy cow management; automatic body condition score; three dimensional; ultrasonography; mjölkkors skötsel; automatisk hullbedömning; tredimensionell avbildning; ultrasonografi;

   Sammanfattning : The objective of this MSc thesis was to investigate parameters reported to be associated with dairy cows’ body condition and its changes. A valid reference of a dairy cow’s body condition was to be suggested and investigated for suitability in the development of a 3D imaging based automatic body condition scoring model. LÄS MER

4. 3. The effects of feeding low levels of concentrate to early lactating dairy cows

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

   Författare :Adriana Llopis Palomares; [2016]
   Nyckelord :early lactation; dairy cows; low concentrate; milk production; energy balance;

   Sammanfattning : Current concerns about sustainable agriculture and the needs to reduce the use of concentrates has led researchers to investigate new approaches in feeding systems for dairy cows. The beginning of lactation is a threatening episode in cow’s life. LÄS MER

5. 4. Automatic estimation of body weight and body condition score in dairy cows using 3D imaging technique

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

   Författare :Dorota Anglart; [2010]
   Nyckelord :dairy cows; body weight; automatic body condition scoring; three dimensional imaging;

   Sammanfattning : The main aim of this MSc thesis was to investigate the possibility of using three dimensional (3D) imaging technique for automatic estimation of body weight in dairy cows of two breeds; Swedish Holstein and the Swedish Red Breed (SRB). Reference data for validation of automatic BCS in SRB has been collected in previous studies and an important part of this study was to collect reference data on one more breed; the Swedish Holstein.
