چکیده
Morphometric variation can be effectively measured within and between populations used as a basis for characterization of different livestock types. The study was aimed at contributing to the process Japanese quail (mottled brown white) through quantitative assessment. Zoometrical data on body weight 11 measurement were taken 747 mottled 272 white from six farms around Ibadan in Southwest Nigeria. Descriptive statistics showed that average reared Nigeria 158.72±2.03, 157.24±1.31, 140.6 ±1.39, 136.27±2.7g female, male, female respectively. Sexual dimorphism observed all traits with higher values recorded females. Significant correlation (P<0.001) measurements. best obtained thigh length r = 0.76 0.70 Factor solution principal component analysis, varimax rotation transformation matrix three factors identified each genetic group (total variance first 27.86, 30.16, 31.88 38.85 quail, respectively). In two strains PC1 had largest share total correlated highly weight, breast length, wing shank length. could describe generalised form quail. PC2 orthogonal loaded heavily girth neck Data also subjected linear stepwise regression. More reliable prediction regression, R² highest R²=0.71 R²=0.81 is linearly related high, positive zoometric measurements indicates these easily parts criteria assessment selection weight.

Mate-choice copying in Japanese quail, Coturnix coturnix japonica
We performed four experiments to examine effects on the mate choices of female Japanese quail, Coturnix coturnix japonica, of observing a male mate with another female. Each experiment was conducted in three phases: (1) a pre-test during which subject females were allowed to choose between two males with which to affiliate; (2) an observation phase, in which subject females either watched or di...

The present studyinvestigated the impact of selection for body weight (BW) on productive performance, predicted BW and genetic improvement of related traits in Japanese quail. Base population, selected parent and F1 progeny were tested. Pens and cages were used for rearing and breeding. A total of 240 birds in two successive generations, 27 sires and 54 dams (as selected parents) were used. Bod...
متن کاملPerceptual compensation for coarticulation by Japanese quail (Coturnix coturnix japonica).
When members of a series of synthesized stop consonants varying in third-formant (F3) characteristics and varying perceptually from /da/ to /ga/ are preceded by /al/, human listeners report hearing more /ga/ syllables than when the members of the series are preceded by /ar/. It has been suggested that this shift in identification is the result of specialized processes that compensate for acoust...
