1. 6. The digesta passage rate among dairy cows with different abilities to consume large quantities of roughage : its impact on the milk production, and the reliability of the chemical fibre marker

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

   Author : Maria Elisabeth Eklund; [2020]
   Keywords : chemical markers; chromium; chromium mordanted fibre; cobalt; concen-trate level; EDTA; iNDF; mean re-tention time; ethylenediaminetetraacetic acid; forage consumption; indigestible neutral detergent fibre; liquid digesta phase; MRT; rumen evacuation; sol;

   Abstract : The objectives of the present master thesis were to investigate the passage rate among lactating Holstein and Swedish red dairy cows to investigate the hypotheses of: 1) The cows’ individual total mean retention time (TMRT) has a negative relationship to the cows’ individual forage intake capacity. 2) A reduced TMRT contributes to a reduced feed efficiency, but a higher milk yield.

3. 7. Field study of the drought’s impact on feeding strategy and biological parameters in early lactation dairy cattle

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

   Author : Mikaela Würtz; [2019]
   Keywords : dairy cattle; drought; energy balance; feeding; metabolism;

   Abstract : The summer of 2018 was unusually warm and dry. For animal production, this resulted in poor pastures, reduced harvests of crops, such as roughage and grains, and increased risk for heat stress in the animals. The drought led to problems as in shortage of animal feed, which made the feeding of dairy cattle difficult. READ MORE

4. 8. Intensively processed silage using Bio-extruder : effects on gas production and forage digestibility

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

   Author : Emma Elgemark; [2019]
   Keywords : digestion rate; timothy; red clover; gas production; NDF digestibility; extruder Abstrac;

   Abstract : The dairy cow requires a high feed intake to maintain a high milk production and forage is a crucial component in dairy cows diet. Forage stimulates chewing activity and rumination which contributes to a normal and effective rumen function. READ MORE

5. 9. Variations in nutritional content of key ungulate browse species in Sweden

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Leonardo Capoani; [2019]
   Keywords : ungulate diet; cervids; nutrition; browsing; Sweden; NIR; NDF; protein;

   Abstract : Understanding variations in the nutritional content of key ungulate browse species is not an easy task. Overall, my study focused to understand seasonal variations in nutritional values, available to wild browsers, found in the main tree and shrub species present in Scandinavia. READ MORE

6. 10. Hur påverkas kotrafiken av blandfodrets sammansättning vid utfodring i automatiska mjölkningssystem?

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

   Author : Maja Blom; [2018]
   Keywords : lata kor; kotrafik; blandfoder; mjölkningsrobot; fullfodermix;

   Abstract : Studiens syfte var att undersöka hur sammansättningen av blandfoder påverkar den frivilliga kotrafiken (hur ofta korna frivilligt går till mjölkning) på gårdar med automatisk mjölkning (AM). Studien genomfördes på elva gårdar i Västra Götalands, Gävleborgs och Västernorrlands län där korna utfodrades med blandfoder på foderbordet totalt 939 kor. READ MORE
