Öğe The effect of reduced dose of PGF2? on certain reproductive parameters in awassi yearlings in anestrus synchronization protocol following the end of the breeding season(Hellenic Veterinary Medical Soc, 2022) Ozbilek, I.; Ergun, Y.; Gozer, A.; Bahan, O.; Alasahan, S.The aim of this study was to investigate the effect of the administration of half or full dose of prostaglandin F-2 alpha (PGF(2 alpha); Gestavet Prost, d-cloprostenol, HIPRA (R)) injection in a routine synchronization protocol following the end of the breeding period including intravaginal sponge (medroxyprogesterone acetate; Espanjovet, HIPRA (R)) and eCG (Oviser 500, HIPRA (R)) on certain fertility parameters in ewes.Two hundred thirty-eight Awassi yearlings (aged one year old) divided into two groups:116 ewes received a half dose (HSDP; 37.5 mu g) of PGF(2 alpha) and 122 ewes received full dose (FSDP;75 mu g).The pregnancy rates were 67.2% and 72.1% for HSDP and FSDP, respectively (P>0.05). The lambing rates were 64.7% and 63.9% for HSDP and FSDP, respectively (P>0.05).The single lambing rate in HSDP(94.7%) was higher (P<0.05) compared to that in FSDP (73.1%). The twin and multiple birth rates of FSDP was higher (P<0.05) than HSDP. As a result, it was inferred that aHSDP could be used in Awassi yearlings without experience of lamb care and in a herd in which single lambing was preferable. Moreover, due to the fact that it is more affordable and not detrimentalto fertility, it was concluded that HSDPcan offer an advantage in large flocks and can be used for manipulating fecundity ratesin yearlings.Öğe The effects of black cumin (Nigella sativa l..) seed on carcass characteristics, kidney oxidant antioxidant levels and ileum histomorphology in Japanese quails(Hellenic Veterinary Medical Soc, 2023) Kazak, F.; Cimrin, T.; Alasahan, S.; Kisacam, M. A.; Kutlu, T.This study aims to determine the effects of supplementation of different level of black cumin seeds (NS) to quail feeds on carcass characteristics, kidney oxidant antioxidant levels, and ileum histomorphology. A total of 432 mixed-gender three days old Japanese quailswere randomly divided into four groups, including 108 animals each and further into 6 replications consisting of 18 chicks. The groups were fed on either a basal diet alone (Control Group) or a basal diet supplemented with NS at rates of 0.5% (NS-0.5 Group), 1% (NS-1 Group), and 2% (NS-2 Group).It was determined that the back+neck weight in the NS-2 group and head weight and ratio in the NS-1 and NS-2 groups decreased. The thigh rate increased in the NS-0.5 group compared to the control and other NS groups. While the wing weight increased in male quails fed with NS-supplemented feed in NS-1 and NS-2 groups compared to the control group, the abdominal fat weight decreased in NS-supplemented groups.Also, the slaughter weight and hot carcass weight in female quails were significantly reduced in the NS-2 group compared to the control group.Kidney glutathione (GSH), glutathione peroxidase (GPx), and male quails' catalase (CAT) values were increased in NS groups compared to the control group. The kidney vitamin C (Vit C) increased only in the NS-2 group compared to the con-trol. In the NS-2 group, the villus height decreased both on a group basis and in female quails, while the villus width decreased only in female quails. Consequently, it was determined that dietary supplementation of NS at rates of 0.5% increased the thigh rate, dietary supplementation at three different level of NS were effective in maintaining the kidney oxidant-antioxidant balance, and the ileum histomorphology did not change except for dietary supplementation of NS at rates of 2%. Therefore, the result of this study can be stated that NS can be used as a natural antioxidant source in the quail diet.Öğe Effects of olive cake meal on serum constituents and fatty acid levels in breast muscle of Japanese quail(South African Journal Of Animal Sciences, 2020) Ozcan, C.; Cimrin, T.; Yakar, Y.; Alasahan, S.This study was aimed at determining the effects of various levels of dietary olive cake meal (OCM) on certain blood parameters and breast muscle fatty acid and cholesterol levels. For this purpose, 400 day-old Japanese quail (Coturnix coturnix japonica) chicks of both sexes were randomly assigned to four trial groups, each including five replicates of 20 animals. The quail were fed on a maize and soybean meal-based basal diet supplemented with 0%, 2.5%, 5% and 7.5% of OCM for six weeks. Dietary supplementation with 5% and 7.5% of OCM decreased total cholesterol and low-density lipoprotein cholesterol levels in the blood serum, and increased cholesterol levels in the breast muscle. Dietary supplementation with various levels of OCM decreased saturated fatty acid and polyunsaturated fatty acid levels, and increased monounsaturated fatty acid and total unsaturated fatty acid levels in the breast muscle. As a result, it was concluded that, olive cake meal, which contains a high level of olive oil, could be incorporated in poultry feed at a level of 5%, owing to its beneficial effects of decreasing serum LDL cholesterol, which plays a major role in the aetiology of cardiovascular diseases, and in reducing saturated fatty acid levels in breast muscle.Öğe Hatching Characteristics and Growth Performance of Eggs with Different Egg Shapes(Facta-Fundacio Arnco Ciencia Tecnologia Avicolas, 2016) Alasahan, S.; Copur, A. G.This study was carried out to identify the effect of the egg shape index on the hatchability, performance, and carcass yield of Japanese quails (Coturnix coturnix Japonica). Eggs were incubated in three groups, according to three different egg shape index (SI) values (Group SI-I: 70.00-73.85%, Group SI-II: 73.86-77.71% and Group SI-III: 77.72-81.57%). Unhatched eggs weight loss (HEWL) was correlated with the egg shape index groups (SI-I: 18.51%, SI-II: 13.34% and SI-III: 13.96%; p< 0.01), but not with the initial unhatched egg weight (HIEW), hatched egg weight (HEW), or eggshell weight of unhatched eggs (HSW) (p> 0.05). The live weight of female and male chicks hatched from SI-I, SI-II, and SI-III egg shape index groups were compared at weeks 4 (female/male: 249.12/237.77, 244.69/236.35, and 241.52/229.72 g, respectively) and 5 (female/male: 304.89/272.42, 295.76/274.34, and 285.42/271.29 g, respectively), and the results showed that females were heavier than males (p< 0.05; p< 0.01; p< 0.001, respectively). The effect of egg shape index on slaughter weight (p< 0.05), left leg weight (p< 0.05), liver weight (p< 0.01) and liver rate (p< 0.01) was significant. Females were heavier at slaughter than males in the egg shape index groups SI-I (p< 0.05), SI-II (p< 0.05), and SI-III (p> 0.05) (female/male: 296.87/283.80, 287.95/278.00 and 283.86/278.10 g, respectively). Males presented higher carcass yield in SI-I (p> 0.05), SI-II (p< 0.01) and SI-III (p< 0.05) (female/male: 74.40/75.92, 74.50/76.44 and 74.80/76.42%) groups than females. Egg shape index had no effect on initial egg weight (IEW), shell blunt end weight (SBW), chick weight, shank length, growth performance or carcass traits, but egg shape indexwas correlated with egg length, egg width, and hatchability of fertile eggs (p< 0.05).Öğe Selected Traits of Hatched and Unhatched Eggs and Growth Performance of Yellow Japanese Quails(Facta-Fundacio Arnco Ciencia Tecnologia Avicolas, 2017) Akpinar, Copur G.; Alasahan, S.; Ayasan, T.This study was carried out to investigate selected traits of hatched and unhatched eggs and chick growth performance of yellow Japanese quails (Coturnix japonica). Eggshell temperature at the time of transfer to the hatcher was higher in hatched eggs (38.09 degrees C) than in unhatched eggs (37.43 degrees C) (p=0.000), lower in eggs with in early embryonic mortality (37.39 degrees C) than those with late embryonic mortality (38.13 degrees C) (p=0.000), and higher in eggs with female chicks (38.14 degrees C) than those with male chicks (37.95 degrees C). Lower eggshell, yolk, and albumen weights were determined in eggs with embryonic mortality of 17-18 days (0.58 g, 3.13 g and 4.96 g) compared with those with 10-16 days (0.67 g, 3.55 g and 5.58 g) and embryonic mortality of 1-9 days (0.75 g, 3.95 g and 6.19 g) (p=0.000). Lower egg weight loss was obtained in eggs with embryonic mortality (13.85%) of 1-9 days than those with embryonic mortality of 17-18 days (26.48%) (p=0.001). Females were heavier at chick weight (8.98 g vs. 8.63 g; p=0.033) and at 4 (231.81 g vs. 211.43 g; p<0.000) and 5(260.69 g vs. 231.87 g; p<0.000) weeks of age than males, and had longer left shanks (34.39 mm vs. 33.61 mm; p=0.004).Öğe The use of propolis extract for the storage of quail eggs(Elsevier, 2015) Akpinar, G. 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.
