  1. 6. Profitability of optimizing biogas production in dairy farms : an experimental case study of a Swedish dairy farm´s usage of nitrogen in digestate as a nutrient resource for crop production

    University essay from SLU/Dept. of Economics

    Author : Nils Hermansson; Albin Åkerblom; [2023]
    Keywords : biogas; optimization; profitability; economic effects; organic; conventional; agriculture; dairy farms; digestate; nitrogen; biogas; optimering; lönsamhet; ekonomiska effekter; ekologiskt; konventionellt; lantbruk; mjölkgårdar; rötrester; kväve;

    Abstract : Biogas has the potential to be a contributor to sustainable energy for electricity, fuel, and heating. Because of that, there are different alternatives for biogas plants. In this study, a farm-based biogas plant for electricity production has been of interest. READ MORE

  3. 7. Fodertillsatsen Bovaer® som metaninhibitor till mjölkkor. Med den aktiva substansen 3-nitrooxypropanol

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

    Author : Vanessa Brodin; [2023]
    Keywords : mjölkko; metan; minska; reducera; 3-NOP; 3-nitrooxypropanol; mjölkkvalitet; mjölkavkastning;

    Abstract : Att minska metanutsläppen från världens mjölkkor ger möjligheten att minska jordbrukets klimatpåverkan. Kornas metanutsläpp från fodersmältningen ger en kraftigare värmande effekt på atmosfären än vad koldioxid gör då metan är ca 32 gånger så kraftfull. Eftersom metan är en kortlivad gas kan minskning av den visa snabba resultat. READ MORE

  4. 8. A comparative study of innovation rennets from Swedish ruminants: calves, kids, and lambs

    University essay from SLU/Department of Molecular Sciences

    Author : Dena Marie Bengtsson; [2023]
    Keywords : Ruminant milk; Swedish bovine rennet; Swedish kid rennet; Swedish lamb rennet; Artisanal cheese production; Rheological properties; Curd yield; Gel firmness; Innovation; Milk coagulation time;

    Abstract : The study aimed to examine Swedish innovation rennets (lamb and kid) and bovine rennets (pepsin and chymosin) in combination with species-specific milk from goat, sheep, and cow. This was accomplished by evaluating the gross composition, casein and whey protein content, casein number of the milk types, as well as rheological properties, such as curd yield, coagulation time, and gel firmness.

  5. 9. Impact of storage at freezing temperatures on casein micelle size, coagulation properties and curd yield in bovine milk

    University essay from SLU/Department of Molecular Sciences

    Author : Ebba Bondesson; [2022]
    Keywords : Casein micelle size; milk coagulation time; gel strength; curd yield; freezing; freeze drying;

    Abstract : Frozen storage is an efficient and convenient way to preserve and transport milk, but the effect from frozen storage needs to be further researched. The objective of this study was to investigate how storage at freezing temperatures (-80°C and -20°C) of frozen and freeze-dried bovine milk samples, respectively, affects pH, casein micelle size, ethanol stability, rheological properties and curd yield.

  6. 10. How does a beef x dairy calving affect the dairy cow’s following lactation period?

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Roberto Espinola Alfonso; [2022]
    Keywords : beef cattle; dairy cattle; crossbreeding; milk yield; fertility; survival;

    Abstract : In dairy x beef breeding, much of the research has focused on the performance of the crossbred calves, yet little focus has been given to the subsequent performance of the cow itself. This study aimed to evaluate the performance of dairy cows for milk yield, fertility, and survival traits after giving birth to crossbred calves, and to compare this to the performance of dairy cows after giving birth to purebred dairy calves.
