We hypothesized that gestational nutrition would affect calf feed efficiency and small intestinal biology, which would be correlated with feed efficiency. Multiparous beef cows (n = 36) were individually fed 1 of 3 diets from d 45 to 185 of gestation: native grass hay and supplement to meet NRC recommendations (control [CON]), 70% of CON NEm (nutrient restricted [NR]), or a NR diet with a RUP s...

Prior studies of intestinal adaptation following massive small bowel resection (SBR) have focused on growth factors and their effects on amplification of the gut mucosa. Since adaptive changes have also been described in intestinal smooth muscle, we sought to determine the effect of targeted smooth muscle growth factor overexpression on resection-induced intestinal adaptation. Male transgenic m...

Dietary supplementation with royal jelly (RJ) may improve growth, antioxidant gene expression, and intestinal capacity, possibly mitigate effects of stress induced by high stocking density (HSD) in zebrafish (Danio rerio). Effects HSD RJ on growth performance, capacity were investigated. A total 240 four-month-old used a 2 x factorial design, four treatments three replications. The consisted no...

this study presents data on age structure, sex ratio, growth, length-weight relationships and condition factor of four populations (n=312) of  two alburnoides species, collected in 2005 and 2006 from the tajan river (caspian sea basin), the ghara-chai and jajrud rivers (namak lake basin), and cheshmeh-ali spring (kavir basin) of iran. sex ratio of the fish, in the studied localities, except in ...

Changes in small intestinal structure, cytokinetics, and function are dynamic ways in which the gut adapts to diet, disease, and damage. Adequate length provides a static 'reserve' permitting an immediate response to pathophysiological changes. The length of the small intestine from conception to adulthood using data taken from eight published reports of necropsy measurement of 1010 guts is des...

background: colibacillosis in poultry, reduces growth and performance, increases mortality and causes economic losses. objectives: an experiment was conducted to study the effect of egg yolk powder and antibody (igy) on intestinal morphology and reduction of bacterial colonization in broilers infected with e. coli. methods: ten laying hens were immunized with e. coli o2: k1. the eggs were colle...

background and aim: it is well - known that sex hormones regulate bone metabolism. sex steroids increase osteoblasts activities and affect growth, remodeling and bone homeostasis. the aim of this study was to examine the effects of sex hormones deficiency on craniofacial growth in rats. methods & materials: fifty, thirty–day–old wistar rats comprised the sample in this experimental study. 25 ma...
