Öğe The effects of dietary garlic powder on performance, egg yolk and serum cholesterol concentrations in laying quails(Czech Academy Agricultural Sciences, 2010) Canogullari, S.; Baylan, M.; Erdogan, Z.; Duzguner, V.; Kucukgul, A.This study was conducted to investigate the effects of garlic powder on the performance, egg traits, egg cholesterol and serum parameters of laying Japanese quails. One hundred and twenty 10-weeks-old quails were allocated to four dietary treatments. Quails were caged individually and fed diets supplemented with 0 (control), 1, 2, 4% garlic powder for 12 weeks. There were significant (P < 0.05) differences among the diets in feed consumption, feed efficiency and egg production as averaged over 12 weeks. The better values for these parameters were obtained from the 1% garlic powder supplemented group. Garlic powder addition did not significantly affect egg yolk index, egg shell weight and egg shell thickness. However, there were significant differences (P < 0.05) in egg albumen index, egg shell index and Haugh unit. There was a significant (P < 0.05) reduction in the egg yolk cholesterol concentration when the dietary level of garlic powder was increased from 0 to 4 g/kg. Plasma high density lipoprotein (HDL) cholesterol concentrations increased (P < 0.05) with increasing levels of dietary garlic powder. Plasma cholesterol (P < 0.05) and triglyceride (P < 0.05) concentration decreased with garlic powder supplementation. It was concluded that garlic powder in the diet of laying quails reduced the plasma and egg yolk cholesterol concentration.Öğe Nutritive Value of Culban (Vicia peregrina) Seeds as Dietary Protein Source for Japanese Quail (Coturnix coturnix japonica)(Medwell Online, 2009) Karaman, M.; Canogullari, S.; Baylan, M.; Kamalak, A.A 6 week feeding trial was conducted to evaluate the nutritive value of raw Vicia peregrina seed as a possible protein source in the diet of Japanese quail (Coturnix coturnix japonica) and identify the limitations to its use arising from palatability or apparent toxicity factors. At the end of experiment the body weight of Japanese quails ranged from 167.1 and 208.4 g and live weight of quails fed diets A and B were significantly (p<0.001) higher than those fed with diet C and D. Feed intake, Body Weight Gain (BWG), Feed Conversion Rate (FCR), Specific Growth Rate (SGR) and the carcass weight of Japanese quail chick fed with diets A and B was significantly (p<0.001) higher than those fed with diets C and D whereas there is no significant (p>0.05) differences among diets in terms of Protein Efficiency Ratio (PER) and Energy Efficiency Ratio (EER). There are no significant (p>0.05) differences among diets in terms of percentage of DP, heart and liver whereas the percentage of gizzard of Japanese quails fed diet with A and B was significantly lower than those fed diets C and D. As a conclusion Vicia peregrine seed has potential as an alternative feed ingredient and can be used up to 10% of diet as protein source in diets of Japanese quails without any adverse effects. Vicia peregrina seed should be processed if inclusion rate exceeded 10% of diet.Öğe USE OF ALLICIN AS AN ALTERNATIVE HATCHING EGG DISINFECTANT VERSUS FORMALDEHYDE FUMIGATION IN BROILER HATCHING EGGS(Taylor & Francis Ltd, 2011) Copur, Gulsen; Arslan, M.; Baylan, M.; Canogullari, S.Allicin, diallyl thiosulfinate, has a strong antibacterial activity against a wide range of gram-negative and gram-positive bacteria. 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.

C.; Canogullari, S.; Baylan, M.; Alasahan, S.; Aygun, A.This study was carried out to evaluate the use of propolis extract on egg storage time of table quail (Coturnix coturnix Japonica) eggs. Propolis is a sticky, resinous, dark-colored material that honey bees collect from young plants. In the experiment, 600 quail eggs were used and eggs were coated with various concentrations of propolis extract (0%: group I, 5%: group II, 10%: group III, 15%: group IV) and treated with 70% ethyl alcohol (group V). A 5-week storage period was implemented, and 120 eggs were used for each group. Consequently, the effects of storage time and shell treatments on storage time and the effects of treatments on the interior quality of eggs were determined. The results of the study confirmed highly significant differences between weekly changes in egg weight loss, albumen-yellow indexes, and Haugh units (P < 0.001). While the difference in yolk index between groups was insignificant, the difference between groups with respect to albumen index (P < 0.001), Haugh units (P < 0.001) albumen pH (P < 0.001), and egg weight loss (P < 0.001) were significant. The significance of the overall difference with regard to Haugh units varied among groups; for example, group IV showed the highest value of 87.73%, followed by group III (87.69%), group II (86.97%), group V (85.53%), and group I (85.21%). Albumen pH levels were increased with increasing storage time for each treatment group. The best egg protection results in terms of interior quality were obtained in eggs coated with 10% and 15% propolis extract during storage.
