some reports indicate a wide range for zn requirements for broiler chickens i.e. from 10.6 to 105 mg kg-1. a number of factors other than dietary zn concentration determine the need for supplementation, principally dietary phytate. therefore, the objective of the present investigation was reevaluation of the zinc requirement for broiler, fed practical diet supplemented with phytase in a dose-re...

Our objective was to study the activity of Ludwigia octovalvis hydro alcoholic extract in rats made experimentally hypertensive by a hypersodic diet. After 21 days this diet, systolic and diastolic blood pressure these animals increases 200.1 ± 1.5 / 155.6 mm Hg, respectively. Administered orally, reduces high pressure. The control group returned its normal value (113.2 1.2/76.3 1) Hg after 24 ...

This study aimed to investigate the effect of tetramethylpyrazine (TMP) supplementation on egg production, nutrient retention and cecal microbiota diversity using 288 commercial Hy-Line brown hens as wk 75 86. Four treatments consisted TMP addition at 0 (control, basal diet), 100, 150 200 mg/kg diet. The results showed that diets supplemented with improved egg-laying rate 77 compared control, w...

Phytoremediation is an efficient approach that uses plants to remediate the polluted environments.The aim of this research was to evaluate phytoremediation ability of Artemisia aucheriin the contaminated soil to Cadmium, Lead, Zinc and Nickel. A greenhouse experiment was performed to investigate the effect of Municipal Solid Waste Compost (MSWC) on phytoremediation efficiency of A....

1. Male Sprague-Dawley rats were fed on either a purified, fibre-free diet or a diet in which half the maize starch was replaced with uncooked amylomaize or potato starch (equivalent to 100 or 200 g amylase-resistant starch (ARS)/kg diet respectively). Changes in short-chain fatty acids (SCFA), pH, ammonia and a number of bacterial variables in caecal contents were then assessed. 2. Both ARS su...
