[Relationships between endogenous carnitine content and growth as carcass traits in swine].

In the present study on 29 growing female Deutsche Landrasse (DL) and Pietrain (Pi) pigs the relationship between endogenous carnitine content in plasma, in the blood lymphocytes and in the sceletal muscles with weight gain and carcass and meat quality is analysed. Significant correlations between carnitine content from rearing pigs to fattening pigs ((r)plasma rearing pig--plasma fattening pig = 0.48, (r)lymphocytes rearing pig--plasma fattening pig = 0.

Indications of associations of the porcine FOS proto-oncogene with skeletal muscle fibre traits.

Skeletal muscle fibre characteristics are key determinants of meat quality. High fibre diameters and shifting towards higher white fibre proportions lead to increasing R-values (degree of desamination of adenosine) and lactate-production, resulting in high incidences of pale, soft, exudative (PSE) meat and stress susceptibility in European and American pig breeds. Development of muscle fibres including their enzymes, is regulated by the MyoD-gene family together with transcription factors like FOS.

[Immunisation of fancy chickens against Newcastle disease].

The German Regulation on Fowl plague which is in force since 1994 laid down that any chicken of all races and all hybrids must be vaccinated against Newcastle disease (ND) in a mode that an adequate immunity is achieved. Onset, duration, and resistance to challenge of immunity induced by vaccination is well documented in the scientific literature for hybrid chicken of the layer and meat types. These data prove also innocuity and efficacy of the registered vaccines.

Cloning, structural organization, and chromosomal assignment of the porcine c-fos proto-oncogene, FOS.

The complete porcine c-fos proto-oncogene (FOS) with flanking regions was cloned and sequenced. FOS consists of four exons at amino acids 1-47, 48-131, 132-167, and 168-380 and includes all the typical motifs of the fos proto-oncogene. The promoter contains consensus sequences for CRE, SRE, CaRE, and the E-Box, as well as an AP-1 site.
