Phosphate is an important mineral nutrient for both human and animals in growth and physiological functions; thus, much effort in the past has been made to clarify the mechanisms governing its absorption. Previous studies have found that epidermal growth factor (EGF) inhibits phosphate absorption in human intestinal cells via modulating the interaction of transcriptional factor c-myb with sodium-phosphate cotransporter (NaPi-IIb) gene promoter. This finding provoked our interest in determining the effect of EGF on NaPi-IIb gene expression in intestinal cells of pigs and the location of EGF-responsive element in the gene promoter...

Positive effects have been observed in offspring from beef cows supplemented with corn dried distillers grain with solubles (DDGS) during late gestation. The hypothesis of this study was that late gestational DDGS supplementation to beef cows would increase blood flow (BF) to the gravid uterus and mammary gland thus impacting birthweight and post-natal growth of the offspring. Experiment 1 investigated mammary gland BF in multiparous cows during late pregnancy. Beef cows were fed a control (CON1) diet of low-quality hay (n = 5) or a supplement diet (SUP1) of low-quality hay with DDGS [1...

The trace element selenium is essential to both dogs and cats. Dry diets are formulated with a large range of ingredients, which may vary in selenium concentration and accessibility. This paper reports equations to predict the average in vitro selenium accessibility from dry pet foods based on essential dietary nutrient concentrations, including crude protein, amino acids and crude fat. Predictive equations were made using stepwise linear regression for extruded and pelleted diets. The equations can be used to aid diet formulation to optimize selenium accessibility within the diet and to prevent selenium deficiency or toxicity...

Plane of nutrition effects on body, tissue and cellular growth in the neonatal calf are poorly understood. The hypothesis that a low plane of nutrition (LPN) would limit skeletal muscle size by reducing fibre growth and muscle progenitor cell activity was tested. At birth, calves were randomly assigned to either a LPN (20% CP, 20% fat; GE=1.9 Mcal/days) or a high plane of nutrition (HPN; 27% CP, 10% fat, GE = 3.8 Mcal/days) in a 2 × 3 factorial design to test the impact of diet on neonatal calf growth, organ weight and skeletal muscle morphometry with time...

Currently, a wide array of plant preparations exerting health-promoting properties are commonly used as feed additives. Among them, Cichorium intybus L. have gained considerable attention as a source of compounds showing prebiotic character. Large body of evidence suggests that products of prebiotic fermentation (short-chain fatty acids) may influence the expression of genes encoding liver enzymes involved in the regulation of energetic metabolism. Given the above, the present study was aimed at estimating the influence of a diet supplemented with chicory root or water extract of chicory inulin on liver proteome in growing pigs...
