  2. 2. Mjölkningssystemen och mjölkningsrutinernas effekt på laktationskurvans uthållighet

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

    Author : Mathilda Börjesson; [2013]
    Keywords : Mjölkningssystem; Mjölkningsrutin; Mjölkningsfrekvens; Uthållighet; Kalvningsintervall;

    Abstract : Mjölkavkastningen har ökat kraftigt de senaste åren och inom mjölkproduktionen eftersträvas högavkastande kor med bra hälsa och som producerar mjölk med hög kvalitet. Ett problem med dagens mjölkproduktion med 12 månaders kalvningsintervall är att korna i genomsnitt producerar mjölk under enbart 2,5 laktation, vilket innebär att de producerar mjölk under mindre än hälften av sin livstid.

    Keywords : pre-stimulation; milk ejection; oxytocin; inhibition; post-stimulation; machine milking;

    Abstract : Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. READ MORE

  4. 4. Genetic Engineering of T Lymphocytes for Cancer Immunotherapy : Optimisation of Gene Transfer

    University essay from Institutionen för medicinsk biokemi och mikrobiologi

    Author : Camilla Lindqvist; [2006]
    Keywords : Chimeric receptor; tumour; retroviral transduction; plasmid transfection; retroviral enhancers;

    Abstract : T lymphocytes can be rendered specific against a wide range of antigens by the genetic transfer of a chimeric receptor, a fusion between the antigen-binding domain of an antibody and the signalling domain of a T cell receptor. The use of such chimeric T lymphocytes has shown promising results for cancer therapy. READ MORE
