Studies on the effects of essential-oil-based feed additives on performance, ileal nutrient digestibility, and selected bacterial groups in the gastrointestinal tract of piglets1
Autor: Wilfried Vahjen, Ortwin Simon, K. Maenner
Publikováno v: Journal of Animal Science. 89:2106-2112
The aim of this study was to assess the effects of 2 different phytogenic products on performance, ileal nutrient digestibility, and composition of the intestinal microbiota. The 2 phytogenic products contained different essential oil mixtures (EOM)

Comparison of a xylanase and a complex of non starch polysaccharide-degrading enzymes with regard to performance and bacterial metabolism in weaned piglets
Autor: Tanja Osswald, Wilfried Vahjen, Klaus Schäfer, Ortwin Simon
Publikováno v: Archives of Animal Nutrition. 61:90-102
Weaned piglets were fed a wheat based diet either non-supplemented or supplemented with a multi-enzyme preparation or a xylanase mono-enzyme preparation, respectively. Both enzyme preparations increased live weight gain nonsignificantly, but only ani

In vitroandin vivocharacteristics of bacterial phytases and their efficacy in broiler chickens
Autor: E.A.I. Elkhalil, Ortwin Simon, Rainer Borriss, K. Männer
Publikováno v: British Poultry Science. 48:64-70
1. Three bacterial phytases derived from Bacillus, Escherichia coli or Klebsiella were compared with a phytase derived from Aspergillus niger in vitro and in vivo. 2. The in vitro results indicated that Aspergillus, E. coli and Klebsiella phytase dis

Weaning pig performance and faecal microbiota with and without in-feed addition of rare earth elements
Autor: K. Männer, Ortwin Simon, Mareike Kraatz, David Taras
Publikováno v: Journal of Animal Physiology and Animal Nutrition. 90:361-368
Two 6-week feeding trials were conducted on a total of 112 newly weaned piglets to examine the recently reported growth promoting effects of dietary rare earth elements (REE) in European pig production. Rare earth element-diets were supplemented with
