Effects of propolis on eggshell microbial activity, hatchability, and chick performance in Japanese quail (Coturnix coturnix japonica) eggs.
Propolis is a sticky resin produced by worker honeybees from substances collected from plants, and it has strong antibacterial and antifungal properties. The purpose of this study was to establish the effects of propolis on egg weight loss, hatchability, chick performance, and to control microbial activity naturally occurring on eggshells. A total of 750 fresh eggs was randomly divided into 5 g...
متن کاملEnzyme on Japanese Quail (Coturnix japonica) Performance
An experiment was conducted to study the eff ect of phytase enzyme (Natuphos 500) supplementation in Japanese quail (Coturnix japonica) (3 to 45 days of age) on body weight, carcass performance, percentage of tibia bone ash and tibia phosphorus. Data were analyzed as a completely randomized design arranged with fi ve levels (150, 300, 600, 1200 and 2400 FTU/Kg) of phytase enzyme as treatments 1...
متن کاملMate-choice copying in Japanese quail, Coturnix coturnix japonica
We performed four experiments to examine effects on the mate choices of female Japanese quail, Coturnix coturnix japonica, of observing a male mate with another female. Each experiment was conducted in three phases: (1) a pre-test during which subject females were allowed to choose between two males with which to affiliate; (2) an observation phase, in which subject females either watched or di...
متن کاملEffect of feeding time on the reproductive performance of Japanese quail (Coturnix coturnix japonica).
Several feeding regimens are applied to improve performance of fertile egg production during times of heat stress. During a period of heat stress (34 to 36 degrees C), two feeding periods were used to measure the impact of feeding time on reproductive performance of Japanese quail (Coturnix cotunix japonica) between 44 and 60 wk of age. Each feeding time treatment had 25 individually caged male...
متن کاملPerceptual compensation for coarticulation by Japanese quail (Coturnix coturnix japonica).
When members of a series of synthesized stop consonants varying in third-formant (F3) characteristics and varying perceptually from /da/ to /ga/ are preceded by /al/, human listeners report hearing more /ga/ syllables than when the members of the series are preceded by /ar/. It has been suggested that this shift in identification is the result of specialized processes that compensate for acoust...
