“…While this observation suggests that lipid content may play an important role (Frisch, 1980;1982), other variables also appear to be important. Body weight, a function of the size of an animal's component parts (Wyatt et al, 1982) which includes testes or ovary-oviduct mass and lipid stores, was generally higher for the light-stimulated treatments than the IP treatment.…”

1. The roles of chronological age, body weight and body composition in the initiation of sexual maturation of Japanese quail (Coturnix coturnix japonica) were investigated by imposing an inhibitory photoperiod (IP), and by the intramuscular injection of turkey growth hormone (GH) or antisera to turkey growth hormone (AGH). 2. Absence of sexual maturity in the IP treatment was accompanied by reduced testis and ovary-oviduct weights, and an increased breast muscle weight expressed as a proportion of body weight. 3. Antisera to turkey growth hormone (AGH) did not completely inhibit the metabolic activities of endogenous GH. 4. The roles of chronological age, body weight and body composition in the initiation of sexual maturity were inseparable.

“…Lacking, however, is evidence on the relationships between these traits with the size and number of adipocytes in specific fat depots. In a companion paper (Wyatt et al, 1981), we reported on the inheritance of lipid deposition in the Japanese quail. Reported here are phenotypic correlations between body weight, breast weight, and various measures of adiposity in the Japanese quail.…”

Phenotypic Relationships Between Adiposity, Breast Weight, and Body Weight in Female Japanese Quail

1982

Data were obtained from 8-week-old females for body weight, breast weight, percentage carcass fat, weight of the sartorial and abdominal fat depots, and the number and size of adipocytes in the abdominal fat depot in parental lines and various crosses of Japanese quail. Correlations of breast weight with body weight, abdominal and sartorial fat depot weight, and percentage carcass fat were positive, significant, and of a similar magnitude. The relationship of body weight with percentage carcass fat was positive and significant, while those between body weight and sartorial and abdominal depot weight and size and number of adipocytes were low. Percentage carcass fat was highly correlated in a positive manner with the weight of the sartorial and abdominal fat depots. Also, there were highly significant positive correlations between depot weights and the number and size of abdominal adipocytes. (

“…A high genetic correlation has been reported between leaf fat and body weight in a randombred control population of quail (Sadjadi and Becker, 1980b). Heterotic effects for weight of abdominal and sartorial fat and percentage carcass fat have been reported; means for the hybrids were lower than for the parental lines of quail (Wyatt et al, 1982). Percent carcass fat has not increased in lines of quail selected for 4-week body weight for 50 generations in comparison to their randombred control (Campion et al, 1982).…”

“…Estimates of heritabilities of abdominal leaf fat and body weight were similar in males, but body weight was more highly heritable in females than abdominal leaf fat (Sadjadi and Baker, 1980b). Data presented by Wyatt et al (1982) also indicate a strong phenotypic correlation between carcass fat, abdominal fat, and sartorial fat at 8 weeks of age.…”

Carcass composition (protein, fat, ash, and percent dry matter), component parts, and dressing yield were determined in lines of quail undergoing divergent selection for yolk precursor, growth, or egg production. Carcass weights and yield percentages were greatest in the line selected for increased 4-week weight and lowest in the line selected for decreased 4-week weight. Carcass weights and yields were not affected by selection for yolk precursor or egg production. Carcass percent protein was lower and percent fat higher in the line selected for increased 4-week body weight but unaffected by divergent selection for yolk precursor or egg production. Percent ash did not vary with genetic changes in body weight, yolk precursor, or egg production. (
