Öğe The Effect of Organic and Inorganic Selenium Supplementation on Egg Production Parameters and Egg Selenium Content of Laying Japanese Quail(Kafkas Univ, Veteriner Fakultesi Dergisi, 2010) Canogullari, Sibel; Ayasan, Tugay; Baylan, Mikail; Copur, GulsenThis study was carried out to determine the effects of organic and inorganic selenium on egg production parameters and egg yolk and egg albumin's selenium contents of laying Japanese quails. A total of ninety 10-week-old quails (Coturnix coturnix Japonica) were allocated to five dietary groups of 18 quails in each. Quails were caged individually and fed diets without supplementation (basal diet), basal diet with inorganic Se (sodium selenite) 0.2 mg/kg Se containing diet and basal diet with 0.1 mg/kg Se, 0.2 mg/kg Se and 0.3 mg/kg Se containing diets for 8 weeks. At the end of the study, there were no significant differences between the groups in final body weight, feed intake, feed efficiency, egg yield and egg weight. Se concentration in egg yolk and egg albumin were higher in Se supplemented groups than control group (P<0.001) and it is established that organic Se supplementation was more effective than the inorganic Se supplementation for increase Se content of quail eggs.Öğe The effect of propolis egg shell coatings on interior egg quality(Eugen Ulmer Gmbh Co, 2008) Copur, Gulsen; Camcil, O.; Sahinler, Nuray; Gul, A.Effects of various concentrations of propolis for egg coating (5%, 8% and 10% of propolis in ethanol) on the interior quality of fresh eggs were evaluated during 4 weeks of storage. During storage, albumen height decreased whereas albumen pH increased. The albumen pH of the uncoated eggs (control; Group I), and the eggs coated with alcohol (Group II) and 5% propolis (Group III) was significantly higher (P 0.05) than the albumen pH of eggs coated with 8% (Group IV) and 10% propolis (Group V). On the other hand, at 4 weeks storage eggs of Groups IV and V had a higher albumen index than the rest of the groups. The HU value of eggs of Groups IV and V were significantly higher than for eggs of Groups I, II and III. Coating with 10% propolis (Group V) resulted in the maintenance of grade 'A' for 2 weeks longer than for the other groups. Propolis did not affect yolk-index (YI) value (p > 0.05). In conclusion, coating of eggs with 10% propolis extract improved interior egg quality during storage.Öğe Effects of dietary Ferula elaeochytris root powder on the growth and reproductive performance of Japanese quail (Coturnix coturnix japonica): It is not recommended in a breeder diet(2009) Canogullari, Sibel; Baylan, M.; Copur, Gulsen; Sahin, A.This study was conducted to investigate the effect of dietary Ferula elaeochytris (FE) root powder on the growth and reproductive performance of Japanese quail (Coturnix coturnix japonica). In the first stage of the experiment (2-5 weeks), 135 two-week old quail chicks were divided into three experimental groups, each including 45 birds: control, FE5 (5 g FE root powder per kg grower diet) and FE10 (10 g FE root powder per kg grower diet). These groups were subdivided into three replicates. Grower diet included 220 g CP and 13.0 MJ ME kg-1. In the second stage of the experiment (5-12 weeks), the quails were treated with the respective FE doses within a layer diet containing 160 g CP and 10.9 MJ kg-1. In the first stage of the experiment (growth period), addition of FE root powder to the grower diet did not affect body weight gain, feed intake or feed conversion ratio (P > 0.05). In the second stage of the experiment (reproductive period), there was no effect on age at sexual maturity, body weight of quail at 50% egg production, the first ten egg weights, mean egg weight, egg production or egg quality characteristics (P > 0.05). Even though the testis weight of male quail was increased by FE treatment in a dose-dependent manner (7.02 g, 9.72 g and 9.57 g in respective groups), fertility and hatchability were totally depressed by FE treatment. In conclusion, FE root powder had no oestrogenic effect on quail hens, but caused infertility in males, suggesting that FE root powder must not be used in breeder quail flocks. © Verlag Eugen Ulmer.Öğe Effects of dietary Ferula elaeochytris root powder on the growth and reproductive performance of Japanese quail (Coturnix coturnix japonica): it is not recommended in a breeder diet(Eugen Ulmer Gmbh Co, 2009) Canogullari, Sibel; Baylan, M.; Copur, Gulsen; Sahin, A.This study was conducted to investigate the effect of dietary Ferula elaeochytris (FE) root powder on the growth and reproductive performance of Japanese quail (Coturnix coturnix japonica).

For this study, 90 10-week-old female Japanese quails (Coturnix coturnix japonica) with similar body size were caged individually and randomly divided into five groups of 18 quails each. One group was fed a normal diet and served as control. A second group was supplemented with 0.2 mg/kg sodium selenite (In-Se) and three groups supplemented with 0.1, 0.2, and 0.3 mg/kg of a commercially available selenium-enriched yeast (O-Se1, O-Se2, and O-Se3, respectively). The eggs were collected at third and fourth weeks of the experiment and were stored at 4A degrees C and 20A degrees C for 0, 15, 30, and 45 days. Extension of the storage time to 45 days at 20A degrees C resulted in significant deterioration of egg quality. The albumen Haugh unit (HU), pH, albumen index, yolk index, and egg weight loss were the most important parameters influenced by the nature of the selenium sources, storage time, and temperature. Storage time and temperature were also significant for egg weight loss, HU, and albumen and yolk indexes. The results show that supplementation with selenium yeast significantly affected shell weight, shell thickness, HU, albumen index, yolk index, and pH. The HU decreased with increased storage time and temperature. Higher levels of Se-yeast administration resulted in greater HU compared to the selenite and control groups.Öğe Effects of Different Selection Methods for Body Weight on Some Genetic Parameters in Japanese Quail(Medwell Online, 2009) Baylan, Mikail; Canogullari, Sibel; Sahin, Ahmet; Copur, Gulsen; Baylan, MakbuleThe aim of this study was to investigate the effects on some genetic parameters of different selection methods for Body Weight (BW) in Japanese quail. For this aim, line M-55 was subjected to individual selection for 5 weeks BW while a reciprocal recurrent selection method was applied to lines R-33 and S-55 Selection lasted 2 generations. In individual lines, the percentage deviation of body weight was an average of 1.41, 1.73 and 2.19% in the 1st generation males, females and mixed sex, respectively. These parameters reached 5.57, 7.44 and 6.29% in the 2nd generation. In the reciprocal recurrent selection, heterosis of BW in the crossbred birds occurred in the positive direction and was 3.22 and 1.95% for R3S5 and S5R3, respectively in the 1st generation. In the 2nd generation, heterosis was calculated as 6.50 and 7.31% in R3S5 and S5R3, respectively, higher than the 1st generation. At the end of the 2 generations, R3S5 had higher heterosis than S5R3 BW increase was similar in the 2 selection methods. Heritability of BW in the individual lines was 0.27 and 0.73 in the 1st and 2nd generation, respectively. In the reciprocal selection, heritability of BW was estimated as 0.37 and 0.19 in the 1st generation and 0.17 and 0.27 in the 2nd generation for R3S5 and S5R3, respectively. As a result, at the end of the 2 generations of selection, an improvement in BW increase was obtained in both selection methods. If selection is continued in these lines, this may be important especially with regards BW.Öğe Effects of divergent selection methods based on body weights of quail on improvement of broiler quail parents(2009) Baylan, Mikail; Canogullari, Sibel; Sahinler, Suat; Uluocak, A. Nazim; Copur, GulsenThe purpose of this study, was to investigate the effects on body weight, weight gain, feed intake and feed efficiency of different selection methods for Body Weight (BW) in Japanese quail. For this purpose, line M55 was subjected to individual selection for 5 week BW while, a reciprocal recurrent selection method was applied to lines R33 and S55. Selection lasted 2 generations. Five weeks body weights in the parents of M55, R33 and S55 lines were obtained and were 273.5, 258.9 and 259.0 g in the beginning generation; 282.9, 284.8 and 279.5 g in the first generation and 284.6, 285.5 and 284.3 g in the 2nd generation. Average 5 weeks old body weights in the offspring of mass selection lines (M55) and offspring of cross-bred lines (R3S5 and S5R3) obtained from reciprocal mating were 279.5, 267.3 and 264.0 g in the 1 st generation and the values obtained were 300.7, 300.5 and 300.2 g in the 2nd generation. In the 2nd generation, body weight increases were higher than the 1st generation, especially in the reciprocal selection lines. Feed consumption of the 1st generation in M55, R3S5 and S5R3 lines were 768.62, 682.61 and 674.18 g and in the 2nd generation were 776.77, 790.64 and 791.71 g, respectively. Feed conversion efficiency was also calculated and was 2.83, 2.63 and 2.63 in the 1st generation and 2.66, 2.71 and 2.73 in the 2nd generation. Applying different selection methods in the present study seeking to increase body weight in quails either in parents or in offspring showed that reciprocal selection lines resulted in higher body weight than initial body weight. Feed consumption and feed conversion efficiency are similar to in the reciprocal selection lines both in the 1st and 2nd generations. © Medwell Journals, 2009.Öğe Effects of Divergent Selection Methods Based on Body Weights of Quail on Improvement of Broiler Quail Parents(Medwell Online, 2009) Baylan, Mikail; Canogullari, Sibel; Sahinler, Suat; Uluocak, A.

Quail eggs were divided into three groups according to their SI (SI-1:<= 76: SI-2:77-78 and SI-3:>= 79%) and into three groups according to their weight (A1:<13.00 g, A2:13.01-14.00 g and A3:>= 14.01 g), respectively. The mean values of hatching weight were found as 8.41, 9.40 and 10.27 g in A1, A2 and A3 egg weight groups and as 8.97, 9.37 and 8.90 g in SI-1, SI-2 and SI-3 SI groups, respectively. The differences between groups in terms of these traits were statistically significant (p<0.01). The fertility rate was not affected significantly by egg weight. The hatchability of fertile eggs was not affected by (SI) groups but it was affected by egg weight groups (p<0.01). The highest hatchability of fertile eggs was observed in A1 group (79.47%) and this was followed by A2 (78.67%) and A3 (74.86%) groups. The difference in hatchability between egg weight groups was statistically significant (p<0.01) and the mean value of this trait in A3 group was lower (64.31%) than those in A1 (72.12%) and A2 (70.45%) groups. The differences between SI groups in terms of hatchability of total eggs, embryonic mortality rates, pipped and discarded chick rates were not statistically significant. The average Body Weights (BW) for the first 2 weeks between egg weight groups were statistically significant (p<0.01) but these differences were not statistically significant after 3 weeks of age.Öğe Egg Weight but not egg shape index, determines the hatchability in Japanase quail (Coturnix coturnix japonica)(2010) Copur, Gulsen; Baylan, Mkail; Canogullari, SibelThis study was carried out to investigate the effect of egg Shape Index (SI) and Egg Weight (EW) on hatchability parameters, hatching weight and weekly live weight in Japanese quails (Coturnix coturnix japonica).

The purpose of this study was to determine the possible use of allicin as a formaldehyde alternative on broiler breeder hatching eggs. The lowest microbial counts on the eggs were obtained from formaldehyde followed by allicin. Microbial counts slightly decreased with the increasing allicin concentrations. Compared to the positive control formaldehyde, allicin treatment lowered the early and late embryonic mortality, and feed conversion ratio, but increased the discarded chick rate, pipping rate and hatchability of the fertile eggs. Allicin concentrations had no significant effect either on hatching or chick growth and development after hatching. These results imply that allicin had a potential as a hatching egg disinfectant since allicin had no detrimental effect on the developing embryo. Biotechnol. & Biotechnol. Eq. 2011, 25(2), 2494-2498Öğe Use of oregano (Origanum onites L.) essential oil as hatching egg disinfectant(Academic Journals, 2010) Copur, Gulsen; Arslan, Mehmet; Duru, Metin; Baylan, Mikail; Canogullari, Sibel; Aksan, EmineThis study was carried out to determine whether oregano (Origanum onites) essential oil works as a disinfectant for hatching egg obtained from broiler breeder flock. Oregano essential oil was applied at two doses 0.55 and 0.75 mu l/cm(3) and two exposure times, 3 and 6 h. The formaldehyde treated eggs were used as positive control and untreated eggs used as negative control. After chemical analysis, the main constituents of oregano essential oil were carvacrol, linalool, para-cymene and y-terpinene. The lowest microbial counts on eggs were obtained from oregano essential oil. Microbial inhibition increased with the increasing essential oil concentrations. Essential oil exposure times had no significant effects on microbial counts. Essential oil fumigation lowered middle embryonic mortality and discarded chick rate, but increased early and late embryonic mortalities compared to formaldehyde treatment. Essential oil doses significantly affected late embryonic mortality, discarded chicks rate, contamination rate, hatchability of fertile egg, body weight at 21 and 42 days, body weight gain and total feed consumption. But, early and middle embryonic mortality were not significantly affected by treatments. These results imply that oregano essential oil had great potential for hatching egg disinfectant and it could be used as natural egg disinfectant.
