  1. 1. Neonatal resuscitation - studies in piglets

    Författare :Rikard Linnér; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Newborn resuscitation; birth asphyxia; cerebral oxygenation; adrenaline; noradrenaline; severe hypoventilation; surfactant; nebulisation; vibrating mesh nebuliser. CPAP; lung deposition; lung distribution.;

    Sammanfattning : Background and aims: “It’s best to start with air” states the current guidelines on the resuscitation of babies at birth. In a piglet model mimicking severe neonatal asphyxia and circulatory arrest, different aspects of resuscitation were investigated (studies I-III). LÄS MER

  3. 2. Consequences of Arterial Switch Operation in Children Born with Transposition of the Great Arteries

    Författare :Cecilia Falkenberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transpositon of the great arteries; arterial switch operation; autonomous nerves system; norepinephrine; heart rate variability; cardiopulmonary bypass; piglets;

    Sammanfattning : Abstract Background: The introduction of the arterial switch operation (ASO) made it the procedure of choice for surgical correction of transposition of the great arteries. A majority of the sympathetic nerves innervate the heart alongside the great vessels; these are therefore likely to be damaged during the surgical procedure; imposing new challenges and questions that need to be addressed.

  4. 3. Factors Influencing Phytate Degradation in Piglets. Feed phytate behaviour and degradation by microbial phytases

    Författare :Katrine Pontoppidan; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pigs; in vitro digestion; P. lycii; inositol phosphates; phytate; phytase;

    Sammanfattning : Phytate, the main storage form of phosphorus (P) in plant feedstuffs, is indigestible for monogastric animals, and phytases are therefore used as feed additives to increase the digestibility of phytate-P and limit the inclusion of inorganic P. However, new and improved phytases are needed to obtain better phytate digestibility and allow for lower inclusions of inorganic P. LÄS MER

  5. 4. Strategic use of straw at farrowing : effects on behaviour, health and production in sows and piglets

    Författare :Rebecka Westin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : According to EU-regulations, sows should be provided with suitable manipulable material, this in order to meet their behavioural needs. "Strategic use of straw at farrowing" means that loose housed sows are provided with 15-20 kg of chopped straw once at 2 days prior to the calculated date of farrowing. LÄS MER

  7. 5. Congenital tremor and splay leg in Swedish piglets : a study of the viral causes and routes of transmission

    Författare :Hedvig Stenberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Congenital tremor (CT) and splay leg (SL) are diseases regularly seen in new-born piglets in Sweden. They are diagnosed based on the clinical picture, which in CT are tremor and sometimes ataxia, and in SL, a lack of adduction of the hind legs. The cause of the clinical signs is unknown, but impaired nerve function due to myelin damage is a theory. LÄS MER
