    Effects of High Light Intensity on Incubation Results in Quail Hatching Eggs During Incubation Period
    (Selçuk Üniversitesi, 2018) Maman, Abdoulaziz Hamissou; Aygün, Ali; Yıldırım, İskender
    The purpose of this experiment was to establish the effects of high light intensity application during embryogenesis on incubation results in Japanese quail (Coturnix coturnix japonica) eggs. A total of 360 hatching eggs were randomly divided into 2 groups. The quail eggs (n= 360) were incubated continuously in the dark (Control; C) and in continuous light at 2900 lux (Light; L) during the first 14 days of incubation. There were no significant (P>0.05) differences in hatchability and embryonic mortality among treatments groups. The incubation time in the light-treated group was shorter than C group. The higher hatch was observed in L group at 390 to 416 h of incubation period than the C group (P<0.01). No significant differences were found between C and L group at other hatching times. These results demonstrate that continuous high light application during incubation affected the hatch time positively without adversely affecting hatchability or embryonic mortality.

    The Effect of in-ovo Injection of Lactobacilla Rhamnosus on Hatching Traits and Growth Parameters of Quails
    (Selçuk Üniversitesi, 2018 Temmuz) Abdulqader, Abbas Fadhıl; Aygun, Ali; Maman, Abdoulaziz Hamissou; Olgun, Osman
    The aim of this study was to investigate the effect of in-ovo injection ofLactobacilla Rhamnosus (0, 16x103, 32x103and 48x103cfu) as probioticsource on hatching parameters and growth performance of quails. In this, atotal of 400 quail hatching eggs, were randomly distributed among 4experimental groups. Each experimental group contained 4 replicates of 25eggs each. In-ovo injections of Lactobacilla Rhamnosus into quail eggs did notstatistically affect incubation characteristics and some tissue weights. A highamount of Lactobacilla Rhamnosus injection into the breeder quail eggsnegatively affected live weight and live weight gain. As a result, it can be saidthat low or medium levels Lactobacilla Rhamnosus injection into quail eggshave no effect on incubation and growth parameters of quails.
