Chick myofibrils in different states of contraction were treated with fluorescein-labeled antibodies. The rabbit antibodies were prepared against chick myosin, light and heavy meromyosins, and actin. For any one state of contraction, a single myofibril was photographed through the phase contrast microscope, stained with one of the antisera, and photographed through the fluorescence microscope. ...

Objective- Because little information was available in the literature about the angiogenic property of enrofloxacin, this investigation was undertaken to evaluate this aspect using an in vivomodel. Design- Experimental study. Animals- Twenty fertile chicken eggs (Ross 308) with the average egg-weight of 55 ± 0.4 g were rand...

Ruminal bacteria and protozoa provide excellent organic phosphorus (P) sources for the host animal. This experiment was conducted to compare the bioavailability of bacterial and protozoal P in comparison with that of dicalcium phosphate (DCP) as a reference phosphorus source. Bacteria and protozoa were isolated from the rumen contents of dairy cows and the chick-model was used to determine the ...
