Estimating the requirement of dietary crude protein for growing blue-breasted quail (Excalfactoria chinensis).
Two experiments were conducted to investigate the requirement for dietary crude protein (CP) in growing blue-breasted quail (BBQ). In Experiment 1, 300 1-day-old quails were randomly assigned to 10 groups according to a 2×5 factorial arrangement of treatments with two metabolisable energy (ME) levels (12.13 and 13.39 MJ/kg) and five CP concentrations (160, 190, 220, 250 and 280 g/kg) for 8 week...
متن کاملThe mechanical power output of the flight muscles of blue-breasted quail (Coturnix chinensis) during take-off.
Blue-breasted quail (Coturnix chinensis) were filmed during take-off flights. By tracking the position of the centre of mass of the bird in three dimensions, we were able to calculate the power required to increase the potential and kinetic energy. In addition, high-speed video recordings of the position of the wings over the course of the wing stroke, and morphological measurements, allowed us...
متن کاملApportioning protein requirements for maintenance v. growth for blue-breasted quail (Excalfactoria chinensis) from 7 to 21 days of age.
The aim of this study was to investigate protein requirements for the maintenance and growth of blue-breasted quail (Excalfactoria chinensis) from 7 to 21 days of age. A total of 180 quails, 7 days old, were randomly assigned to 36 cages and for 2 weeks were fed diets with a metabolisable energy concentration of 12.13 MJ/kg and a dietary CP concentration of 125, 150, 175, 200, 225 or 250 g/kg. ...
متن کاملA possible role of chorion protease in shell membrane degradation during development of quail embryos.
In the eggs of the quail Coturnix japonica, the limiting membrane demarcates the shell membrane at the interface with the albumen and decreases in width during the hatching process. This study was done to identify agents that affect the width of this limiting membrane. Zymography tests on extracts from extraembryonic tissues, yolk sacs, or chorioallantoic membranes, or all three, showed proteol...
متن کاملThe development of hepatogenic potency in the endoderm of quail embryos.
Hepatogenic potency of the endoderm is detectable in the anterior half of the endoderm of quail embryos older than 2-somite stage when endodermal fragments are cultured with or without heterologous chick mesenchymes, in the coelomic cavity of 3-day chick embryos. On the other hand, the posterior half of the endoderm never has hepatogenic potency. The hepatogenic potency of the endoderm is gradu...
