an experiment was conducted to study the effects of dietary levels of extruded full fat soybean (effsb) on performance, blood metabolites and intestinal morphology of broiler chickens. a batch of ffsb was wet extruded at 155 °c, 15 seconds to provide the extruded full fat soybean (effsb) sample. one hundred and forty four d-old ross 308 male broiler chicks were divided into 12 groups with 12 bi...

A trial was conducted to evaluate the performance of broiler birds which supplemented with a commercial inactivated probiotic. Four hundred and fifty day old broiler chickens were allocated into 3 treatments with 6 replicates each. Each replicate was placed on clean wood shavings in floor pens receiving feed and water ad libitum. In treatment 1, feed was supplemented with 500 g/ton of a heat-in...

(iranian birds). 36% of birds were endemic and 64% were migrant. cosidering the species variety in markazi province, sylvidae family is number one. the population of corvidae family are more than oth...

As colony-specific wintering ecology of small and medium-sized seabirds is poorly understood, it has been generally assumed that winter conditions have the same effect on all individuals from any given colony. However, advances in global positioning technology now allow researchers to investigate movements of smaller seabirds. We tracked black-legged kittiwakes Rissa tridactyla using geolocator...

The aim of this study was to determine the threonine requirement of broilers during a subclinical Clostridium infection. Three experiments were performed: experiments 1 and 2 to investigate the dose-response of threonine supplementation during infection and experiment 3 to validate the threonine requirement during infection. In each experiment, 1-d-old Ross 308 male broilers were used. An infec...

Experiments were conducted to determine effects of Santoquin (ethoxyquin) and oxidized fat on liver and intestinal reduced (GSH) and oxidized (GSSG) glutathione, and pulmonary hypertension syndrome (PHS) mortality. Male broilers were randomly assigned in a 2 x 2 factorial consisting of 3.5% normal (NF) or oxidized (OxF) fat with or without ethoxyquin (E). Body weights and feed intake were monit...
