D-alanine (DAL) has been successfully used as a marker of bacterial nitrogen (N) in the small intestine of cows. This study compares DAL contents of intestinal bacteria in digesta of cows and pigs with respect to diet and sampling site. In isolated i

The main aims of this experiment were: 1) to study the sites and extent of digestion of the nutrients in wheat (var. Soissons) and its by-products (bran, middlings) and in recombined wheat (flour 1 bran 1 middlings); 2) the contribution of microbial

Apparent digestibility (ileal and overall) of nutrients as evaluated with PVTC-cannulated or ileo-rectal anastomised pigs fed diets containing two indigestible markers

Publikováno v: Livestock Production Science. 62:133-141

The techniques of post-valve “T” caecal cannulation (PVTC) and ileo-rectal anastomosis (IRA) and the indigestible markers Cr 2 O 3 and TiO 2 for determination of ileal digestibility of nutrients were studied in this experiment. The results showed

Introduction There is a great need for better understanding of the intestinal bioavailability of B-vitamins and the factors that influence it. In food products, however, nutrient content does not necessarily imply the proportion of nutrient content a
