This article summarizes the experimental knowledge on efficacy, possible modes of action, and aspects of application of phytogenic products as feed additives for swine and poultry. Phytogenic feed additives comprise a wide variety of herbs, spices, and products derived thereof, and are mainly essential oils. The assumption that phytogenic compounds might(More)
In the study presented here, the effect of zinc deficiency on mRNA expression levels in liver and jejunum of adult rats was analyzed. Feed intake was restricted to 8 g/day. The semi-synthetic diet was fortified with pure phytate and contained either 2 microg Zn/g (Zn deficiency, n = 6) or 58 microg Zn/g (control, n = 7). After 29 days of Zn depletion(More)
Five potential reference genes for RT-qPCR application, namely histone H3, beta-actin, GAPDH, ubiquitin and 18S rRNA, were evaluated for normalization of gene expression in four selected tissues (liver, kidney, thyroid and abdominal fat). Tissues were derived from fattening pigs exposed to different amounts and type of dietary iodine. Two software(More)
In the present study, transcript profiling was carried out in liver biopsies from high-yielding dairy cows at week 5 of lactation in order to identify genes and pathways regulated by feeding rumen-protected conjugated linoleic acid (CLA) during the transition period. Analysis of a bovine whole genome microarray revealed a total number of 130 annotated(More)
