The purpose of this study was to provide a better understanding of the physiological role of endogenous net organic acid production in rats consuming their usual diet. Balance studies were performed over 24 h, and urine was collected in the day and night portions of the diurnal cycle. A supplemented low-electrolyte diet (LED) was fed to determine whether urinary organic anions were identical to...

digestibility in broiler chickens fed on corn-soybean meal based diets. the experimental diets consisted of 1.corn-soybean meal based control diet 2. control diet supplemented with pectinas, 3. control diet supplemented with cellulase, 4. control diet supplemented with pectinase + cellulose, 5. control diet supplemented with pectinase + hemicellulase and 6. control diet supplemented with pectin...

This study examined how eco-organic feed affects the growth performance, nutrient efficiency, utilisation, and body composition of gilthead seabream. Six different diets were tested, including a control diet (CONT) without organic ingredients four with 100% ingredients: trout (TRO), seabass (SBS), poultry (POU), mix (MIX), along (ORG) containing 30% fishmeal. The experiment lasted 70 days, fish...

Zinc is required for normal bone development and cartilage formation. The purpose of this study was to assess the effect of with adding organic Zn (alone or phytase inclusion) at the reduced dose to growing male Ross 308 chickens on somatic axis and bone tissue metabolism. 200 one-day old broilers were divided into the negative control group fed diet without Zn or phytase inclusion, positive co...

A study was conducted to investigate the effects of organic acids (OA) and competitive exclusion product (CE) on growth performance, intestinal morphology, and concentration of volatile fatty acids in the cecal content. The experiment lasted for 10 wk. Four hundred twenty 1-d-old female commercial cross turkey poults (British United Turkeys, BUT Big 9) were distributed into 4 treatments with 5 ...

A study was conducted to evaluate the short-term effects of feeding two dietary Se sources at various Se levels on the transfer of Se to the dam's milk and nursing pig. Six dietary treatments were arranged in a 2 x 2 factorial arrangement with two additional treatments in a randomized complete block designed experiment. Inorganic (sodium selenite) or organic (Se-enriched yeast) Se sources were ...

The aim of this study was to compare the effects of a new organic Se [2-hydroxy-4-methylselenobutanoic acid (HMSeBA)] with routinely used mineral and organic Se sources (sodium selenite and selenized yeast) on chosen performance criteria and Se deposition in egg and muscle of laying hens. A total of 240 laying hens (40 wk of age) were randomly assigned to 6 treatments for 56 d with 8 replicates...

Produce Inflate Human Organophosphate Exposure Assessments We read the recent report by Curl et al. (2003) concerning organophosphate (OP) pesticide exposures with considerable interest. It seems to have escaped their notice that OP pesticides yield the same dialkylphosphate (DAP) products in urine whether they are human metabolites or formed in treated fruits and vegetables and consumed in the...

Minerals and vitamins play an important role in animal nutrition with beneficial effects on animal reproductive performance. To investigate this issue, 44 Ghezel ewes weighing 55±  2 kg (Mean±SD) and 2-3 years old were randomly divided into groups (n=11), to investigate the effect of the selenium and vitamin E supplementation on blood hormones and metabolites and possible reproductive performan...
