Japanese quail (Coturnix japonica) were reinforced with food for traversing a runway for either 18 or 36 trials, administered at a rate of 1 trial per day. Then, all animals received 18 extinction trials. The latency to run from the start box to the goal box was the dependent variable.

The vitamin A uptake cells in the anterior pituitary, thyroid gland, and pancreas of Japanese quails, coturnix coturnix japonica, were examined by the use of Sudan III staining, toluidine blue staining, fluorescence microscopy and electron microscopy. After excess vitamin A administration, most of interstitial cells, corresponding to fibroblasts, increased markedly the size and number of lipid ...

usefulness of Japanese quail (Coturnix coturnix japonica) as an expenT z n t a l animal was first pointed out about eight years ago (WILSON, ABBOTT and ABPLANALP 1959, 1961; PADGETT and IVEY 1959).

The present investigation was designed to assess the response of Japanese q...

This study was carried out to determine the effect of adding ginger powder at different levels (0.0, 0.5, 1.0, 2.0%) ration on performance, blood parameters and meat quality characteristics male Japanese quails. 48 quail (Coturnix coturnix Japonica) 28 days age were used in study. The experiment for 21 4 replications a cage with 12 quails each treatment groups consisting rations containing powd...
