  1. 1. Heritability of methane emission in Swedish Red cattle in northern Sweden

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

    Author : Lucy Chipondoro; [2024]
    Keywords : methane emission; heritability; swedish Red cattle; dairy cow;

    Abstract : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. READ MORE

  3. 2. 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.

  4. 3. Effect of the Cooling Rate and the Surface Film Composition on the Colloidal Stability of Whey Protein Based Emulsions of Triacylglycerols

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Charlotte Schüler; [2022]
    Keywords : Emulsion technology; Fat crystallization; Emulsified triglycerides; Colloid science; Food technology; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : The goal of this project was to investigate the effect and interplay of formulation and processing parameters on the colloidal stability of emulsified triacylglycerols from a product quality perspective. Different methods to quantify and monitor this effect over time were evaluated. READ MORE

  5. 4. Anpassningsförmåga till klimatförändringar hos kor

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

    Author : Stina Emriksson; [2019]
    Keywords : anpassningsförmåga; klimatförändringar; värmestress; värmetolerans; Bos indicus; Bos taurus;

    Abstract : Syftet med litteraturstudien är att undersöka skillnaderna mellan kons underarter och se vad det finns för åtgärder för att anpassa dem för framtida klimatförändringar. I dagsläget bedöms klimatförändringarna leda till högre temperaturer globalt som kan resultera i värmestressade kor. READ MORE

  6. 5. Validation of the role of a SNP in the VPS35 gene and its effect on non-co-agulating milk in Swedish Red Cattle

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

    Author : Gro Hylén; [2018]
    Keywords : VPS35; genotype; SNP; SR; cow; NC-milk; MCP; genomic selection;

    Abstract : From earlier studies, it is clear that nearly 20 % of the Swedish red (SR) dairy herd possess milk that doesn’t coagulate within 40 minutes after rennet addition. This is a problem when processing milk into cheese because lower cheese yield is the result of non-coagulating (NC) milk. An estimate of 17. READ MORE
