The relationship between radiographic disc calcification score and FGF4L2 genotype in dachshunds.

Background: The relationship between radiographic disc calcification score and FGF4L2 genotype has been reported in only a small number of dachshunds.

Hypothesis: A genotype with either 0 or 1 FGF4L2 copy will be associated with a lower number of calcified discs (lower K-n) compared with a genotype with 2 FGF4L2 copies.

Animals: Dachshunds registered with the Norwegian or Finnish Kennel Clubs for which both K-n and FGF4L2 genotype are known (n = 407).

Associations between housing and management factors and reproductive performance in 327 Norwegian sheep flocks.

Background: Housing sheep in insulated, warm buildings, which is common in Norway, involves high buildings costs, but has not been reported to improve health and performance. Few studies have dealt with the association between housing and management and reproductive performance.Data on housing and management during the indoor period from a questionnaire were merged with herd level data from the Norwegian Sheep Recording System, and the material included 327 sheep flocks.
