Adaptability of Japanese quail chicks to conditions of simulated weightlessness.
The objective of this study was to evaluate the adaptability of young Japanese quail chicks to the simulated weightlessness, represented by hypodynamy. Unsexed hatchlings were subjected to hypodynamy on either the first, second or third day of age and reared under these conditions to 21 days of age. During this period, the control quail chicks were housed in a floor box. The effect of hypodynam...
متن کاملProductive and Physiological Responses of Japanese Quail Embryos to Light Regime during Incubation Period
Various factors play important roles in influencing hatchability efficiency and growth performance during embryonic and post-hatch life, such as genetic, egg characteristics and incubation environment (Christensen, 1995; Nestor and Noble, 1995; Narushin and Romanov, 2002; Petek et al., 2003; Abiola et al., 2008). Light is one of the environmental factors that improves embryonic growth and hatch...
متن کاملComparative Evaluation of Some Properties of Chicken and Japanese Quail Eggs Subjected to Different Storage Methods
This study investigated the potential effects of egg quality indices at 95% confidence level in order to minimize quality loss during different storage conditions. The chicken and quail eggs’ quality indices including weight, albumen index, yolk index, Haugh index in fresh eggs as well as after storing in moist sawdust, oil, and refrigerator were measured for six weeks. The results revealed tha...
متن کاملAn Investigation into Enterobacteriaceae Responsible for Early Mortality in Japanese Quail Chicks and Their Antibiotic Susceptibility Patterns
Quail is an alternative source of protein for humans. These birds can be affected by common bacterial infections. Bacterial contamination of egg is the most common cause of mortality in Japanese quail chicks. In order to study the role of some members of Enterobacteriaceae responsible for early mortality in Japanese quail chicks, 100 dead or moribund quail chicks were obtained from 10 different...
متن کاملFeeding and Growth of Japanese Quail (coturnix C. Japonica) Chicks with Unpredictable Food
We investigated the effect of unpredictable feeding times on feeding activity and body mass gain in fast growing Japanese quail (Cotumix c. japonica) from 7 to 31 d of age. Quail chicks were subjected to a long day length (18L:6D) with ad libitum food during (1) 17.5 h of the light period, starting 0.5 h after lights-on (group A, n = 14), (2) 6 h of the light period, starting 0.5 h after lights...
