Utilisation of iodine from different sources by sows and their progeny.

Objectives: The aim of the study was to compare iodine utilization from different sources by sows and their progeny and the levels of T3 and T4 in their serum.

Design: Pregnant Czech Large White × Landrace sows were fed with an experimental KPK diet (a diet for lactating sows) 14 days before parturition until weaning (at a piglet age of 28 days). In group A (n=50, 10 sows, 40 piglets) the feed was supplemented with KI (0.

The effects of soybean selenium proteinate on tissue selenium and meat quality traits in finishing pigs.

The purpose of the present study was to evaluate the effects of soybean selenium proteinate on Se tissue retention and meat quality in pigs. In group A (n = 11) the mixtures were supplemented with soybean selenium proteinate, in group B (n = 11) with sodium selenite and in group C (n = 11) with Se-enriched yeast (0.3 mg Se per kg in all groups).

Effects of high dietary levels of Se-enriched yeast on tissues selenium content and meat quality traits - a model study in rats.

Objectives: The aim of the trial was to evaluate effects of high dietary levels of Se-enriched yeast on selenium concentrations in muscle and liver tissue and on the meat quality traits in rats.

Design: The experimental feed mixtures were fed to Wistar Albino rats for a period of 10 weeks. They differed in the dose and in the form of Se supplement.

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.

The significance of pork as a source of dietary selenium - an evaluation of the situation in the Czech Republic.

The aim of this paper is to review current knowledge of the significance of pork as a source of Se for human consumption, and to evaluate the selenium content in pork produced in the Czech Republic. Selenium has an important role in human health. Pork could possibly be an important source of Se for the human diet.
