- Abstract:
- ... 1. The effect on feed efficiency of two probiotics, one prepared with Saccharomyces boulardii and the other with Bacillus cereus var. toyoii, was tested in broilers infected with Salmonella enteritidis. 2. One-day-old chicks were divided at random into three groups and fed commercial feed devoid of antibiotics: group 1 was fed with non-supplemented feed, group 2 was supplemented with S. boulardii ...

- Abstract:
- ... 1. Glucose transporter (GLUT) proteins, one of which is the major insulin-responsive transporter GLUT4, play a crucial role in cellular glucose uptake and glucose homeostasis in mammals. The aim of this study was to identify the extent of mRNA expression of GLUT1, GLUT2, GLUT3 and GLUT8 in chickens intrinsically lacking GLUT4. 2. GLUT1 mRNA was detected in most tissues of 3-week-old broiler chicke ...

- ... 1. Three experiments were conducted to determine growth of broiler chicks fed on test diets formulated to be deficient or adequate in tryptophan (Trp) using gelatin by-product as a means of generating a Trp deficiency. Growth response estimates of broiler chicks to graduations of Trp were determined by dose-response criteria and regression analyses. Experiments were conducted using broiler chicks ...
