Response to Selection for Body Weight in Japanese Quail (Coturnix coturnix japonica)
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 کاملL-Dopa Feeding Induces Body Growth and Reproductive Conditions in Japanese Quail, Coturnix coturnix Japonica
It is obvious from several studies that the different neurotransmitters are associated with various metabolic activities of the body directly or indirectly via their effects on hypothalamic/pituitary hormone but regarding the control of reproductive system catecholamines seem to have a central role. In view of above fact the present study was designed to test whether neurotransmitter precursor ...
متن کاملNutrient Benefits of Quail (Coturnix Coturnix Japonica) Eggs
Cross-sectional study of quail eggs was conducted to evaluate the nutritional compositions of carbohydrate, fat, protein, calories, vitamin, minerals and sex hormones. The results showed that average of each whole quail egg weight was 10.67 g. Their contents of ash, carbohydrate, fat, protein and moisture were 1.06, 4.01, 9.89, 12.7 and 72.25 g 100g -1 , respectively. Total energy in calories o...
متن کاملGenetic Parameters Estimated for Sexual Maturity and Weekly Live Weights of Japanese Quail (Coturnix coturnix japonica)
Covariance components and genetic parameters of weekly live body weight from hatching to six weeks of age and age of sexual maturation were estimated in a laying type Japanese quail line. The univariate and bivariate animal model analysis included hatching group and sex as fixed effects. Each trait was analysed with animal as random effect to fit the additive direct effect. Additional random ef...
متن کاملMETABOLIZABLE ENERGY AND CRUDE PROTEIN REQUIREMENTS OF TWO QUAIL SPECIES (Coturnix japonica and Coturnix ypsilophorus)
The present study aimed to investigate the effects of different levels of dietary metabolizable energy (ME) and crude protein (CP) on performance and carcass characteristics of Japanese (Coturnix japonica) and Brown (Coturnix ypsilophorus) quails during a 42 d feeding trial. A total of 720 (360 per each species) one week-old quail chicks were randomly (by species) distributed between 72 cages a...
