(Kafkas Univ, Veteriner Fakultesi Dergisi, 2015) Narinç, Doğan; Aygün, Ali; Küçükönder, Hande; Aksoy, Tülin; Gürcan, Eser Kemal
In this study, it was aimed to introduce the Bootstrap technique and to reveal the relationship between measurements of yolk color fan grades and digital colorimeter that is used for determining the yellow color of egg by utilizing this technique. For this purpose, a total of 1350 samples of 15 color grades of Roche yolk color fan and L* (lightness), a* (redness), b* (yellowness) values in the same samples were compared. The means, standard errors and confidence intervals for each color parameters of fan grades have been demonstrated by the Bootstrap technique. The grades of Roche yolk color fan in terms of L* values have been divided into 10 groups (P < 0.01), while only divided into 9 groups in terms of b* values (P < 0.01). According to the means of Redness (a*), all of the Roche yolk color fan grades (15 grades) have been determined as independent from each other (P < 0.01). With the Bootstrap method, the standard error values of means were decreased by 42.03%, 35.38% and 30.24%, respectively, and the confidence intervals were narrowed by the ratio of 42.03%, 35.38% and 30.24%, respectively. The results of the study were compared with the results of the study that was conducted by using Roche yolk color fan which is cheaper but less reliable and by using digital colorimeter method which is expensive but reliable.

(Pagepress Publ, 2007) Soysal, Mehmet İhsan; Tuna, Yahya Tuncay; Gürcan, Eser Kemal; Özkan Ünal, Emel; Kök, Süleyman; Castellano, N.; Barone, Carmela M. A.
In Turkey most farmers keep 1-2 buffaloes for family consumption and this system is very widespread in villages while farms with around 100 heads are located near to the big cities. These two most common housing systems were used to contribute to the somatic characterization of Anatolian buffalo in the context of a wide typification programme of this buffalo aimed to improve its productive and reproductive potentiality in agreement with a sustainable development. 76 males and 127 females of the Istanbul district and 32 males and 70 females raised in Danamandra village of Silivri district were measured. On each buffalo, withers height, rump height, body length, chest depth and chest width were determined. The results showed a significant difference between males and females starting from 12 months in buffaloes of Danamandra village and from 3 years of age in animals of Istanbul district.
Association between milk protein polymorphism and milk production traits in Black and White dairy cattle in Turkey
(Academic Journals, 2011) Gürcan, Eser Kemal
Milk protein polymorphism such as alpha(s1)-casein (alpha(s1)-Cn), beta-lactoglobulin (beta-Lg), beta-casein (beta-Cn) and kappa-casein (kappa-Cn) of Black and White dairy cattle were investigated in this study. The genetic structure of herd was examined for these loci. At the sametime the relationships between milk protein types and some milk production traits were determined. Milk production traits were chosen as milk yield, average daily milk yield and lactation length. These traits were associated with milk protein types. Genetic variants of milk protein were identified by starch gel electrophoresis containing mercaptoethanol and urea. The allele gene frequencies of A, B, and C of alpha(s1)-Cn loci and A, B of beta-Cn were found to be 0.01; 0.97; 0.02 and 0.95; 0.05 respectively. Furthermore, the allele frequencies of A, B of kappa-Cn and A, B of beta-Lg were found to be 0.68; 0.32 and 0.55; 0.45 respectively. For alpha(s1)-Cn BB phenotype was found to have higher milk yield than those of alpha(s1)-Cn AB and alpha(s1)-Cn BC phenotypes, and beta-Lg AA phenotype was detected to have higher milk yield than those of beta-Lg AB and beta-Lg BB types but were not statistically important. It was concluded that the genetic structure of the four loci were determined in Black and White cattle, but there was no significant association between the milk protein types and milk production traits in the study.

(Academic Journals, 2010) Gürcan, Eser Kemal; Erbas, Cengizhan; Çobanoglu, Özden
This paper aims to search genetic structures of purebred Kivircik sheep raised in Turkey based on erythrocyte potassium and glutathione types and also to determine the relationship between these components and some blood parameters. The phenotypic frequencies were 68% for LK and 32% for HK erythrocyte potassium types in the purebred Kivircik breed. The allele gene frequency of K H and K L loci were calculated as 0.56 and 0.44 respectively. There was no relationship detected between gender factor and blood parameters. But, significant relationships were obtained between erythrocyte potassium types and some blood parameters (Na-wb, Na-e, K-wb, K-p, K-e, Na-e + K-e; p<0, 05). At the same time, the correlation coefficient between Ke and Nae was calculated as R = -0.58, (p<0.01). But, correlation coefficient was not significant between blood parameters and hematocrit value (PCV). All animals were detected as low types in terms of glutathione level (GSH(h)). The mean of erythrocyte glutathione was determined as 29.79 mg/dL in red blood cell. The mean of erythrocyte potassium concentrations (Ke) were 9.22 and 23.47 mmol/L for the LK and HK types of animals, respectively and the mean differences between LK and HK types were statistically important in this study (p<0.01).
Comparison of Fatty Acid Composition between Female and Male Japanese Quail Meats
(Hindawi Ltd, 2015) Geçgel, Ümit; Yılmaz, İsmail; Gürcan, Eser Kemal; Karasu, Salih; Dülger, Gizem Çagla
The objective of the present study was to compare the proximate analysis, fatty acids composition, omega fatty acids, trans fatty acids (TFAs), and ratio of the total poly unsaturated fatty acid (Sigma PUFA) and total saturated fatty acid (Sigma SFA) of female and male quail meats. Significant differences were not observed between pH, crude fat, moisture, and ash content of female and male quail meats (p > 0.05). The male quail meat had higher fat and ash contents and lower moisture content than those of the female quail meat. The pHs of male and female quail meat were found to be 6.22 and 6.21, respectively. The results of the fatty acid composition analysis showed that C18:1 (42.14-41.23%), C16:0 (24.31-25.76%), C18:2 (13.82-13.42%), and C18:0 (7.49-7.32%) were found as the major fatty acids in the female and male quail meats. Total TFAs, Sigma SFA, monounsaturated fatty acids (Sigma MUFA), and Sigma PUFA content of the female and male quail meats were found to be 2.79-2.82%, 33.22-34.65%, 49.70-48.72%, and 14.29-13.81%, respectively.
Comparison of growth curves using non-linear regression function in Japanese quail
(Taylor & Francis Ltd, 2018) Kaplan, Selçuk; Gürcan, Eser Kemal
This study was conducted to determine the goodness of fit of Gompertz, Logistic, Von Bertalanffy, Richards, Levakovich and Janoschek growth models in Japanese quail. Therefore, weekly live-weight data obtained from 372 females and 339 males were fitted. Females' live weights were found to be higher than that of males, and the first divergence in the growth of female and male birds occurred in 21-28 days, and it survived until the experiment (P<.001). The coefficient of determination (R-2), adjusted coefficient of determination (adj. R-2), mean square error (MSE), Akaike's information criteria (AIC) and Bayesian information criterion (BIC) were used to determine the best growth model. R-2 and adjusted R-2 values of the growth models were similar and close to 1, indicating that all models perform well in describing age-related changes in live weight in quail. Based on the MSE, AIC and BIC values, Richards model was determined to be the best fitting model to the growth data of both sexes. Consequently, it has been demonstrated that Richards function which has a flexible structure in terms of inflection point is the most appropriate growth function for both female and male birds.
Conservation and Sustainable Use of Farm Animal Genetic Resource
(Zootekni Federasyonu (ZF), 2020) Soysal, M.ihsan; Ünal, Emel Özkan; Gürcan, Eser Kemal
Livestock plays a special role in the provision of ecosystem services and is an important part of agricultural ecosystems. They provide the function of providing livestock ecosystem services by converting natural elements that are not suitable for human consumption into nutritious foods such as grazing, roaming, chewing feces and urine production and by moving around in response to fluctuations in the availability of resources and climate. Farm animal genetic resources are animal species that are or may be used for food and agricultural production, populations within each species, wild populations, local breeds and primary populations, standard breeds, selected lines, breeds varieties, strains and conserved genetic materials; all are currently classified as breed. Animal genetic resources are the primary biological capital for livestock development tendered it alto food security and sustainable rural development. Preserving the diversity of farm animal genetic resources is of great importance to meet future breeding challenges. Animal genetic resources have been developed for use by humans as a result of long processes of domestication and selection and if they are no longer used for consumption, they must become extinct. The process of conserving animal genetic resources is a process that concerns not only the breeder, but also the public, as it can be used by the wider public. The most important option, referred to as insurance value, sourced from the fact that it includes protecting, conserving the breeds for the future and keeping the breeds retention of options that will respond to unforeseen future events such as climate change and production environment change.As a precaution to the future environmental conditions such as climate, shelter, feed and hygiene, the existing variation in farm animal genetic resources should be protected and developed in this review, biodiversity is generally carried out at international level and its major component of farm animal genetic resources conservation and sustainable use studies have been examined in the world and in Turkey.

(2011) Çobanoglu, Özden; Gürcan, Eser Kemal; Pala, A.
Main purpose of this study was to investigate genetic polymorphisms of Saanen (S), Maltese (M) and Turkish Hair (TH) goats based on erythrocyte potassium and glutathione types. It was also designed to detect the association between these components and some blood parameters depending on the breed comparisons. The phenotypic and alleles frequencies were calculated for potassium and glutathione types of all three breeds. The difference between low and high potassium (LK and HK, respectively) types for the means of erythrocyte potassium concentration (Ke) were statistically important for all breeds (p<O.Ol). The significant relationships between erythrocyte potassium types and blood parameters of erythrocyte sodium (Nae), whole blood potassium (Kwb), plasma potassium (Kp), erythrocyte potassium (Ke) were observed for S and TH goats. On the other hand, the important relationships were detected between erythrocyte potassium types and blood parameters of whole blood sodium (Nawb), Nae, KwbKp Ke, total monovalent cation concentration in erythrocyte (Nae+Ke) for M goat breed (p<0.05). The correlation coefficient between Na, and K, blood parameters was important and it was ranged from -0.26 to -0.34. In addition, Maltese goat breeds had a higher K, than the others but Na, was higher in TH goats. Even if parity and birth type differences were not statistically important for all blood parameters, there was indication of significant differences for these values except hematocrit value (peV), N~ and GSH concentrations depending on the potassium types within breed (p<0.05) and also among all breed analyses (p<O.OOI). © Medwell Journals, 2011.

Determination of the association of GHR/Alul gene polymorphisms with milk yield traits in Holstein and Jersey cattle raised in Turkey
(Copernicus Gesellschaft Mbh, 2021) Çobanoglu, Özden; Kul, Ertuğrul; Gürcan, Eser Kemal; Abaci, Samet Hasan; Çankaya, Soner
This research was carried out to determine the effect of a specific single nucleotide polymorphism (SNP) region in exon 10 of the growth hormone receptor (GHR) gene on milk production traits in Jersey and Holstein cows raised in Turkey. Milk samples were recorded as a test day milk yield (TDMY) and an adjusted based 305 d milk yield (305-DMY). Also, milk component traits were detected. Based on the scope of this study, a total of 748 dairy cows, including 305 Holsteins raised in the Marmara Region and 163 Holstein and 280 Jersey raised in the Black Sea Region, were genotyped for the GHR gene using the RFLP-PCR technique. Jersey cows carrying the GG genotype (5.24 %) were associated with higher fat content (P < 0.05). Jersey cows with GG and AG also had a higher protein content (3.44 % and 3.38 %, respectively) (P < 0.05). Similarly, the protein content was the highest in Holstein cows with the GG genotype (3.46 %) (P < 0.01), whereas Holstein cows having AA genotypes displayed higher TDMY (24.64 kg/d) (P < 0.05) and 305-DMY (8472.4 kg) (P < 0.01). The estimated increase in milk protein and fat contents due to the G allele was 0.07 % and 0.22 % in the Jersey breed, respectively. On the other hand, allele A was highly related to an increase in protein yield and 305-DMY of 0.04 and about 675 kg in the Holstein breed, respectively. The GHR gene should be considered as a potential candidate gene in marker-assisted selection programs to improve the performance of milk and related traits in Turkey dairy cattle populations.

(Agricultural Research Communication Centre, 2019) Gürcan, Eser Kemal; Çobanoglu, Özden; Kul, Ertuğrul; Abacı, Samet Hasan; Çankaya, Soner
This study was to determine the genetic polymorphism in terms of the DGAT1 gene among Holstein and Jersey and indigenous Native Black, East Anatolian Red and Grey Steppe in Turkey. The frequencies of K allele for the DGAT1 gene were calculated as 0.59, 0.54, 0.53, 0.62, 0.52, and 0.54 for Jersey, Holstein (Black Sea Region), Holstein (Marmara Region), and Grey Steppe, East Anatolian Red, and Native Black breeds, respectively. The F-IS values of the populations for the DGAT1 gene were detected all negative values. In overall population, F-IS value was found as 76%. The expected deviations from the Hardy-Weinberg Equilibrium in terms of the DGAT1 locus were found significant in these six different populations (P<0.01). The genetic distance values among the populations were calculated between 0.0001 and 0.0089. Based on the cluster analysis, Holstein, Native Black and East Anatolian Red were located in close cluster; however, Jersey and Grey Steppe were grouped in different cluster.

(Scientific Technical Research Council Turkey-Tubitak, 2022) Gürcan, Eser Kemal; Genç, Serdar; Kaplan, Selçuk; Özdil, Fulya; Ünal, Emel Özkan; Bulut, Hasan; Soysal, Mehmet İhsan
This research aims to determine the morphometric characteristics of the donkey (Equus asinus) populations reared in Turkey. For this purpose, live weights and body measurements were collected from 500 donkeys. The donkeys were grouped according to the factors of color, age, sex, and province and the live weights (LW) (kg), withers heights (WH), rump heights (RH), body lengths (BL), chest circumferences (CC), chest depths (CD), front shank circumferences (FSC), head lengths (HL) and ear lengths (EL) (cm) of the donkeys were measured. In the study, the males were found to have higher values of live weight, withers height, rump height, and chest depth than the females (p < 0.05). Significant differences in the live weights of the donkeys were seen by province, age, color, and sex (p < 0.01 and p < 0.05). Significant differences were found among the age groups as well (p < 0.01). Accordingly, the least squares means of the animals aged 1???3 years, 4???5 years, 6???8 years, and 9 years and over for live weight were measured as 112.10 ?? 3.11 kg, 141.54 ?? 2.76 kg, 153.98 ?? 2.42 kg, and 152.95 ?? 2.34 kg, respectively. The least squares mean of live weights were also determined as significant between the female and male animals (138.08 ?? 1.96 kg) and (142.21 ?? 2.25 kg), respectively (p 0.05). The highest correlation coefficient was calculated between live weight and body length among the donkeys (r = 0.83). Furthermore, the classical method (CM) and the fixed object photo (FOP) method were compared for photographed animals in the study. No difference in WH, RH, CD or HL was seen between the two methods (p 0.05). In conclusion, the morphometric characteristics of the donkeys were determined and it was shown that the populations were not distinguished clearly from each other and that this was fundamentally due to the transitions among the donkey populations for long years.

(Agricultural Research Communication Centre, 2017) Çobanoglu, Özden; Gürcan, Eser Kemal; Çankaya, Soner; Kul, Ertuğrul; Abaci, Samet Hasan; Ülker, Mehmet
This study aims to determine the correlations between the test-day milk yield (TDMY) and the fat and protein content as well as the fat and protein yields in Holstein dairy cows and to investigate the effects of lactation period and sampling season on these parameters. The study material consists of 1.380 records of a total of 151 head of Holstein dairy cows raised on a private farm in Samsun province. In the study, the mean TDMY, fat content, protein content, fat yield and protein yield were recorded as 20.6 +/- 5.10 kg, 3.97 +/- 0.734%, 3.23 +/- 0.276%, 0.81 +/- 0.210 kg and 0.66 +/- 0.160 kg, respectively. The effects of lactation period and sampling season on the TDMY, fat content, protein content, fat yield and protein yield were found statistically significant (P<0.01). Statistically significant negative correlations were determined between the TDMY and the fat and protein content, but positive and statistically significant (P<0.01) correlations between the TDMY and the fat and protein yields. In conclusion, it might be stated that the effects of lactation period and sampling season should also be taken into account to improve milk yield and milk components.

(Oxford Univ Press, 2018) Sabuncuoğlu, Kübra Melis; Korkmaz Turgud, Firdevs; Gürcan, Eser Kemal; Narinç, Doğan; Şamlı, Hasan Ersin
Lighting is crucial in poultry rearing and the subjects with light intensity, source, and color having been addressed in numerous studies. Numerous studies with monochromatic light from light-emitting diode (LED) bulbs have been reported. In the current study, fertile Japanese quail eggs were exposed to a dark environment (Control) or monochromatic green (560 nm) and blue (480 nm) lighting throughout incubation. There were no significant differences in hatch weight, hatchability, total embryonic mortality, hatch time, growth performance, and slaughter-carcass traits in the study (P > 0.05). Furthermore, the lowest mean in terms of early embryonic mortalities (12.37%) was determined in the group treated with green LED light-ing (P < 0.05), whereas it was discovered that the lowest mean in terms of late embryonic mortalities (13.59%) was in the group treated with blue LED lighting (P < 0.05). During the test time, the green LED group showed higher averages in terms of the number of peeps and first defecation time as response to environmental stimuli (P < 0.05). The highest mean for jumping (7.6 times) was detected in the group treated with blue LED lighting (P < 0.05). In conclusion, it was revealed that the blue and green LED lighting applied to the Japanese quail eggs in incubation had no effects on incubation traits, growth, and slaughter-carcass traits but had positive effects on some behavioral traits.
