Short-term spatial memory responses in aged Japanese quail selected for divergent adrenocortical stress responsiveness.
Stress-induced glucocorticoids can dampen learning and spatial memory via neuronal damage to the hippocampus. Cognition losses can be transient (associated with acute stress episodes) or permanent as in aged individuals who show chronic glucocorticoid-induced accelerated brain aging and neurodegeneration (dementia). Thus, chronic versus acute stress effects on spatial memory responses of quail ...
متن کاملEgg Production Traits and Egg Quality Characteristics in Black and Brown Plumage Color Lines of Japanese Quail
The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...
متن کاملEffect of Dietary Betaine and Folic Acid Supplementation on Performance, Egg Folate Content and Egg Production of Japanese Quail
A study was conducted to investigate the effects of different betaine (BET) (0.0, 0.5 or 1.0 g/kg) and folic acid (FA) (0.0, 4.0 or 8.0 mg/kg) levels on performance, egg FA concentration and egg production of laying quails using 288 forty-two day-old Japanese quail in a 3 × 3 factorial arrangement of treatment based on randomized complete design. The results showed that none of the performance ...
متن کاملQuantitative Trait Loci for some of Behavior and Performance Traits on Chromosome 4 of Japanese Quail
The current study was conducted to identify the quantitative trait locus (QTL) for the body weight at age 1, 7, 14, 21 and 28 days and daily gain at age 0-1, 1-2, 2-3 and 3-4 weeks, slighter carcass weight and tonic immobility in Japanese quail. Two divergently lines of wild and white Japanese quail which maintained in the Animal Science Research Center of the Shahid Bahonar University of Kerma...
متن کاملeffect of divergent selection for body weight on egg production and other reproduction traits in japanese quail
the aim followed in the present research was to investigate the effect of nine generations of divergent selection on some reproductive and egg production traits in japanese quail. the results indicated that selection for 4-week body weight, increased the age at sexual maturity of hw and of lw lines, in comparison with control, for about 7 and 3 days, respectively (p
