Divergent selection for four-week body weight in Japanese quail (Coturnix coturnix japonica): response to selection and realized heritability
The Japanese quail has been utilized as a research species in establishing the genetic relationships that may also be present in other species. Divergent phenotypic selection for 4-wk BW was conducted for three generations in high (HW) and low (LW) lines. Within each line, 50 females and 25 males were selected among 600 birds, based on 4-wk BW. Mean BW at 4 wk of age in the base generation was ...

متن کاملA controlled comparison of three very-low-calorie diets: effects on weight, body composition, and symptoms.
To determine the optimal energy intake of very-low-calorie diets (VLCDs), 76 obese women were randomly assigned, in a double-blind fashion, to one of three liquid-formula diets: 1758 kJ/d (420 kcal/d), 2763 kJ/d (660 kcal/d), or 3349 kJ/d (800 kcal/d). Weight, body composition, symptoms, mood, and acceptability of the diet were assessed throughout the 6-mo study. There were no significant diffe...
متن کاملEffect of an 8-Week Anaerobic Gymnastics Training on Static, Dynamic Balance and Body Composition in Obese and Normal-Weight Children
Introduction: Among all the factors that affect human health and success, maintaining balance and paying attention to physiological characteristics and body composition can be very effective in childhood. This study aimed to evaluate and compare the effects of anaerobic gymnastics training (AGT) on static, dynamic balance, physiological indexes, and body composition in obese and normal-weight b...
متن کاملResponse to selection and genetic parameters of body and carcass weights in Japanese quail selected for 4-week body weight.
The current study was conducted to investigate the effect of short-term selection in Japanese quail for 4-wk BW and estimate genetic parameters of BW, carcass traits, and egg weight. A selected line and control line were randomly selected from a base population. In each generation, 39 sires and 78 dams were used as parents for the next generation. Data were collected over 2 consecutive hatches ...
