Two experiments were conducted to examine the effect of level of dried distillers grains plus solubles (DDGS) supplementation (0, 10, 20, and 30%; DM basis), replacing steam-flaked (SF) corn in finishing diets, on characteristics of digestion (Exp. 1) and growth performance (Exp. 2) in calf-fed Holstein steers. In Exp.1, 4 cannulated Holstein steers (349 ± 12 kg) were used to evaluate treatment...

Lactobacillus kefiranofaciens M1 is a novel probiotic strain that was isolated from kefir grains. Previously, we have demonstrated the immunoregulatory, anti-allergic, anti-asthmatic and anti-colitis abilities of L. kefiranofaciens M1 in a number of in-vitro and in-vivo experiments. However, whether the effects of L. kefiranofaciens M1 are elicited directly on the host or act by regulating the ...

abstract: kefir is fermented milk that has a unique flavor because of acetaldehyde, diacetyl, acetoin and ethanol. the aim of this study was to evaluate flavor and aroma compounds present in kefir. two types of starter (christian hansen and sacco) and three levels of temperatures (30, 33 and 35oc) were used for the preparation of kefir samples. the samples were analyzed for acetaldehyde, diacet...

Pure and/or mixed isolated microbial cultures, in the dairy sector known as starters, are widely used in the manufacture of numerous fermented (cultured) milk products as well as in butter and cheese making (Bylund, 1995). The starter is added to the sterilized milk-based fermentation media and allowed to grow under controlled and, if necessary, on-line regulated process conditions. During the ...

The characteristics of 58 strains of Lactobacillus spp. isolated from kefir were studied. These strains were tested for adherence to human enterocyte-like Caco-2 cells, resistance to acidic pH and bile acid, antimicrobial activities against enteropathogenic bacteria and inhibition of Salmonella typhimurium attachment to Caco-2 cells. The best probiotic properties were observed in L. acidophilus...

The use of functional foods (probiotics and prebiotics) has been demonstrated to be effective for the treatment or control of several diseases. Further well designed trials to examine the effects of different probiotic components are required. It is important to establish separate functions and to gain further insight into the underlying mechanisms that include competitive exclusion and modific...
