Background and Aims: Newcastle disease virus (NDV) infection have been established in at least 241species of birds representing 27 of the 50 orders of the class.NDV isolate were obtained from infected ostrich flock during the outbreaks of ND in Iran 2012. The F gene fragment which codes the main functional region of the F protein was obtained by RT-PCR and sequenced. Methods: From the pathotype...
s of papers 35 142 Citric acid improves phytate phosphorus utilization in two breeds of chicks fed a corn-soybean meal diet. K. A. Rafacz*, C. Martinez, J. L. Snow, D. H. Baker, and C. M. Parsons, University of Illinois. Previous research in our laboratory has shown that citric acid improves phytate phosphorus utilization in crossbred chicks (New Hampshire x Columbian) fed a P-deficient corn-so...
Six experiments (EXP) were conducted to evaluate growth performance of different breed crosses of broiler chicks fed diets containing soybean meal, soy protein isolate (SPI), soy protein concentrate (SPC), or rice and casein. Cornish x Plymouth Rock (C x PR; EXP 1, 3, 4, 5, and 6) or New Hampshire x Columbian (NH x C; EXP 2 and 4) cross chicks were used. The chicks were fed a corn-soybean meal ...
Three colipases were purified from pancreas of two birds (ostrich and turkey) and one mammal (dromedary). After acidic and/or heat treatment and precipitation by sulfate ammonium and then ethanol, cofactors were purified by Sephadex G-50 gel filtration followed by ion-exchange chromatography first on Mono S and then on Mono Q. One molecular form was obtained from each species with a molecular m...
The pecten oculi is a structure peculiar to the avian eye. Three morphological types of pecten oculi are recognized: conical type, vaned type and pleated type. The pleated type has been well studied. However, there exists only scanty data on the morphology of the latter two types of pectens. The structure of the vaned type of pecten of the ostrich, Struthio camelus was investigated with light a...
