Comparative Growth and Plumage Development in Coturnix and Bobwhite
نویسنده
چکیده
$ EVERAL releases of Japanese Quail (Coturnix coturnix japonica) have been l__. made in the United States since 1956. This attempted stocking appears to have been unsuccessful, as were releases of this form and C. c. coturnix made more than fifty years ago (Phillips, 1928). However, recent interest in the bird has pointed up its qualities as an experimental animal. As Padgett and Ivey (1959) pointed out, Coturnix is easy to handle, hardy, has short breeding cycles, and great egg-laying ability. Objectives of the present study were to provide detailed information on eggs, growth, and plumage development of C. c. japonica, and to find accurate criteria for determining age in this bird. Bobwhites (Colinus virginianus) reared under the same conditions as the Japanese Quail furnished a standard for comparison of growth rates and plumage development.

A total number of 66 day old Japanese quail chicks divided into 2 treatment groups (33 in each treatment) with 3 replications in each having 11 birds (male, 5 and female, 6) were reared on floor and in cage system for a period of 5 weeks to know the effect of rearing system on growth performance and carcass characteristics. At the age of 35 days, average body weight and feed intake were 102.15 ...
متن کاملAssociation of Tyrosinase (TYR) and Tyrosinase-related Protein 1 (TYRP1) with Melanic Plumage Color in Korean Quails (Coturnix coturnix)
TYR (Tyrosinase) and TYRP1 (Tyrosinase-related protein 1) play crucial roles in determining the coat color of birds. In this paper, we aimed to characterize the relationship of TYR and TYRP1 genes with plumage colors in Korean quails. The SNPs were searched by cDNA sequencing and PCR-SSCP in three plumage color Korean quails (maroon, white and black plumage). Two SNPs (367T→C and 1153C→T) were ...
متن کاملDustbathing and Feather Lipid in Bobwhite (colznus Vzrgznzanus)
The general sequence of dustbathing components in Bobwhite (Co&us uirginiunus) has been described and the frequency of some of the components found to increase with dust deprivation ( Borchelt et al. 1973 ) Upon replication, a sex X deprivation interaction for the frequency of some components was discovered, with male Bobwhite exhibiting greater increases than females ( Borchelt 1972). I observ...

Myoglobin has an important physiological role in vertebrates, and as the primary sarcoplasmic pigment in meat, influences quality perception and consumer acceptability. In this study, the amino acid sequences of Japanese quail and northern bobwhite myoglobin were deduced by cDNA cloning of the coding sequence from mRNA. Japanese quail myoglobin was isolated from quail cardiac muscles, purified ...
متن کاملProduction of donor-derived offspring from cryopreserved ovarian tissue in Japanese quail (Coturnix japonica).
Cryopreservation of avian ova and embryos is challenging because of the yolky structure of the egg. As an alternative, with the development of effective cryopreservation protocols, ovarian tissue cryopreservation could be used for cryobanking for birds. Pieces of ovarian tissue of week-old Japanese quail (Coturnix japonica) were frozen at 0.5 degrees C/min in a programmable freezer or vitrified...
