Comparative morphology of normal and cleft minipigs demonstrates dual origin of incisors.

Objective: The incisors of the mammalian dental arch develop from tissues arising from separated facial prominences. These primordial craniofacial structures undergo complex morphogenetic processes as they merge and fuse in a time and space dependent fashion. However, local contributions of precursor facial prominences to the incisors that develop subsequently remain unknown.

Evaluation of selenium status in pure bred duroc sows and their progeny.

Objectives: The aim of this trial was to determine selenium status in pure bred duroc sows and their progeny and to compare it to Czech Large White x Landrace breed.

Design: The pregnant duroc sows (n=12) and pregnant Czech Large White x Landrace sows (n=12) were fed identical diets supplemented with sodium selenite.

Results: During lactation significantly higher serum Se concentrations (p<0.
