Publication Evaluation of some environmental and genetic factors csn3 and agpat6 gene on milk yield and composition in saanen goats(Univ Zagreb Vet Faculty, 2021-01-01) Dincel, Deniz; DİNÇEL, DENİZ; Ardicli, Sena; ARDIÇLI, SENA; Samli, Hale; ŞAMLI, HALE; Ogan, M. Mustafa; Balci, Faruk; BALCI, ÖMER FARUK; Bursa Uludağ Üniversitesi/Veteriner Fakültesi.; 0000-0002-8015-9032; 0000-0003-2758-5945; 0000-0003-2382-1330; AAH-6192-2021; O-3394-2019This study was designed to determine the effect of some environmental factors on milk yield and composition in Saanen goats and the effect of CSN3 and AGPAT6 gene polymorphisms on milk production traits. Saanen goats were genotyped for milk traits, and the samples were collected during the lactation, and the milk yield/compositions of each goat were specified. In terms of the CSN3 and AGPAT6 genes, the genotypes were defined by PCR-RFLP. The milk yield (MY), lactation length (LL), protein, fat, total solid (TS), solid not fat (SNF), casein, lactose rates and yields were as follows; 388.9 +/- 17.5 kg, 243 +/- 5.81 days, 3.29 +/- 0.05%, 3.59 +/- 0.07%, 11.60 +/- 0.13%, 8.43 +/- 0.06%, 2.57 +/- 0.04%, 4.31 +/- 0.03%, 11.21 +/- 0.47 kg, 12.79 +/- 0.64 kg, 40.95 +/- 1.82 kg, 29.53 +/- 1.31 kg, 8.82 +/- 0.37 kg, 15.40 +/- 0.74 kg respectively. The determined genotype and allele frequencies of CSN3 and AGPAT6 gene were as follows; FF (%99.20), MF (%0.80), F (0.996), M (0.004); GG (%12), GC (%43.20), CC (%44.80), G (0.336), C (0.664). The impacts of lactation length on all milk yield parameters (protein, fat, TS, SNF, casein, lactose. MY) (P<0.001); the age on all milk yield parameters (P<0.001) and the protein, fat, SNF, casein rates (P<0.05), the TS rate and LL (P<0.01) were found to be significant. The birth type was not found to significantly affect any milk yield parameters. Although Saanen goats showed the variation for the AGPAT6 gene (g.9263C>G), the herd was found to be monomorphic (FF) for the CSN3 gene. The effect of the AGPAT6 gene on milk traits in Saanen goats was determined not to be statistically significant. Environmental factors, such as maternal age and lactation length, were found to significantly affect some milk traits in Saanen goats. So consideration of factors such as maternal age or lactation length could be useful for improving breeding strategies for dairy goats.Publication Evaluation of candidate gene effects and environmental factors on reproductive performance of holstein cows(South African Journal Of Animal Sciences, 2019-01-01) Ardıçlı, Sena; ARDIÇLI, SENA; Şamlı, Hale; ŞAMLI, HALE; Dinçel, Deniz; DİNÇEL, DENİZ; Soyudal, B.; Balcı, F.; BALCI, ÖMER FARUK; Bursa Uludağ Üniversitesi/Veteriner Fakültesi; 0000-0003-2758-5945; 0000-0002-8015-9032; 0000-0003-2382-1330; O-3394-2019; AAH-6488-2021; AAH-6192-2021This study investigated the impact of nine polymorphisms located in the CSN2, CSN3, CSN1S1, CSN1S2, and parity on reproductive traits. The analysis was conducted on 165 Holstein-Friesian cows. Genotypes were identified using PCR-RFLP. The data of reproductive traits for four lactations were evaluated. Statistical analysis was carried out using least squares of the GLM procedures. Results indicated that CSN2 had significant effects on days before first insemination and first insemination to pregnancy interval. The SNP at the CSN3 was significantly associated with gestation length. A novel effect of OLR1-C223A on age at first calving was observed in the present study. Moreover, DGAT1 and LGB markers were significantly associated with calving interval and days before first insemination, respectively. In addition, significant environmental effects were as follows: calving year with days before first oestrus, days open, and first insemination to pregnancy interval; season with days open, first insemination to pregnancy interval, and calving interval; parity with days before first oestrus and days open. The present results and novel associations may therefore be useful and indicative for future studies on a genetic basis of cattle reproduction traits.Publication Determination the effect of CSN1S1, CSN3 and AGPAT6 genes and lactation rank on physicochemical properties of goat milk(Sivar-soc Italiana Veterinari Animali Reddito, 2020-08-01) Deniz, Dincel; DİNÇEL, DENİZ; Sena, Ardicli; ARDIÇLI, SENA; Hale, Samli; ŞAMLI, HALE; Faruk, Balci; BALCI, ÖMER FARUK; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Genetik Anabilim Dalı.; 0000-0002-8015-9032; 0000-0003-2758-5945; AAH-6192-2021; O-3394-2019The physiochemical properties of milk are important factors in terms of the process of dairy production, quality, and profitability. However, the knowledge about the effect of genetic factors such as CSN1S1, CSN3, and AGPAT6 genes on these traits is insufficient. The objective of this study was to determine the effect of these genes and lactation rank (LR) on total acidity, citric acid, density (density), free fatty acid (FFA), freezing point degree (FPD) and urea parameters. A total of fifty (n=50) Saanen goats, which is known as the highest milk-producing breed within the goats were genotyped using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) methods. For genetic analysis, the blood samples were taken from the jugular vein by aseptic conditions. The DNA isolations were performed by the phenol-chloroform method from blood samples. Milk samples were collected during the lactation and evaluated by Fourier transform infrared (FTIR) spectroscopy for the physicochemical properties of Saanen goat milk. The statistical analysis was carried out using the least-squares of the GLM procedures. The results indicated that no significant differences were confirmed between the investigated genes with the physicochemical properties of goat milk. However, the effect of the AGPAT6 gene on density and the effect of LR on citric acid composition was found tended to be significant. Moreover, we determined the significant correlations between the physicochemical properties in the present study. According to the results, acidity was correlated with the citric acid (-0.304), density (0.641), FFA (-0.332) significantly. Other significant correlations were observed between the citric acid and FPD (0.275), LR (-0.313); the density and FFA (-0.315), FPD (0.436); the urea and LR (-0.369). These results and novel correlations may be useful for future studies on evaluating the potential impact of AGPAT6 gene on these traits to achieve breeding and commercial goals in the goat production and dairy industry.Publication Analysis of FecB, BMP15 and CAMP gene mutations in sakiz sheep(Kafkas Üniversitesi Veteriner Fakültesi Dergisi, 2015-07-01) Dincel, Deniz; Ardıçlı, Sena; Soyudal, Bahadir; Er, Mehlika; Alpay, Fazlı; Şamlı, Hale; Balcı, Faruk; DİNÇEL, DENİZ; ARDIÇLI, SENA; Soyudal, Bahadir; Er, Mehlika; ALPAY, FAZLI; ŞAMLI, HALE; BALCI, ÖMER FARUK; Uludağ Üniversitesi/Veteriner Fakültesi; 0000-0002-8015-9032; 0000-0003-2758-5945; 0000-0003-2382-1330; O-3394-2019; AAE-4562-2019; AAH-6488-2021; AAH-6192-2021; FXS-6181-2022; CNK-1840-2022; I-5009-2019Fertility traits, such as the ovulation rate and the number of offspring at birth, are genetically regulated by fecundity genes. This study was performed to identify DNA polymorphisms in Booroola (FecB), Galway (FecX(G)), Inverdale (FecX(I)) and Calpastatin (CAST) genes in Sakiz sheep. A total of 71 ewes were genotyped for gene or allelic polymorphisms in the genes listed above using the PCR-RFLP method. The results obtained from this study indicated that all of the Sakiz ewes sampled were non-carriers for FecB, FecX(G) or FecX(I) mutations. However, genotypic frequencies in the CAST gene were 0.59, 0.36 and 0.05 for AA, AB and BB, respectively. A significant deviation from Hardy-Weinberg equilibrium for the CAST gene was not observed in the investigated breed (P>0.05). As a result, more extensive screening is required as tests for newly discovered mutations are developed. Additionally, this study is the first to report a genetic polymorphism in the CAST gene in Sakiz sheep.Publication Associations between c.2832a > g polymorphism of CAST gene and meat tenderness in cattle: A meta-analysis(Kafkas Univ, Veteriner Fakultesi Dergisi, 2022-09-01) Uzabacı, Ender; UZABACI, ENDER; Dinçel, Deniz; DİNÇEL, DENİZ; Bursa Uludağ Üniversitesi/Veteriner Fakültesi.; 0000-0002-9634-0055; JPL-5273-2023Genes or genetic markers related to meat quality have been studied for many years. The CAST gene is one candidate gene affecting meat tenderness in cattle. This meta-analysis aimed to examine the association of c.2832A>G polymorphism of the CAST gene and meat tenderness in cattle. According to the determined criteria, 17 studies were included in the meta-analysis, and pooled ratios of allele and genotype frequencies were calculated. In addition, the combined Warner-Braztler Shear Force values were calculated for three studies that reported these values according to genotypes for the meat tenderness feature. Heterogeneity between studies and publication bias were also tested. As a result of the meta-analysis, pooled ratios of AA, AG, and GG genotypes are 0.578, 0.342, and 0.080; pooled ratios of A and G alleles are 0.777 and 0.223. The highest pooled ratios were obtained for AA genotype and A allele. The combined Warner-Braztler shear force values were calculated as 3.707, 3.893, and 5.137 kilogram-force for AA, AG, and GG genotypes. The highest mean shear force value was obtained for the GG genotype. In conclusion, the meta-analysis results examined the relationship between c.2832A>G polymorphism of the CAST gene and meat tenderness were closer to the population parameter. This study may improve genetic selection and provide new strategies to increase meat quality in cattle.Publication Establishment of AA-NAT, SCD, PROP1, and IGFBP3 gene frequency distributions in Karacabey merino and kivircik sheep breeds(Hellenic Veterinary Medical Soc, 2023-07-01) Dinçel, Deniz; Çobanoğlu, Özden; DİNÇEL, DENİZ; ÇOBANOĞLU, ÖZDEN; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Genetik Anabilim Dalı; JKT-4511-2023; ESN-8515-2022The aim of the current study was to investigate the genotypic dispersion of AA-NAT, SCD, PROP1, and IGFBP3 genes in the target population. Primarily, the genomic DNA was isolated from blood samples by the phenol/chloroform method. The genomic analyses were performed on a total of 160 Karacabey Merino (KM) (n=80) and Kivircik sheep (n=80). The PCR-RFLP method was used to determine the genotype of the SNPs. Deviation from Hardy-Weinberg equilibrium (HWE) and population genetic assays such as observed (Ho) and expected (He) hetero-zygosities, effective allele numbers (Ne), and the polymorphism information content (PIC) were calculated for each gene in the population. As a result, there was no deviation from HWE was determined except SCD and PROP1 gene in KM. The most frequent genotypes were found AA (66,25% and 87,50%) for AA-NAT gene, CC (93,75% and 91,25%) for SCD gene and CC genotype (70,00% and 56,25%) for PROP1 gene in KM and Kivircik sheep. Both breeds were detected monomorphic in terms of the IGFBP3 gene. In conclusion, the other regions of the IGFBP3 gene which were determined as monomorphic in the studied flock could be researched. Moreover, further studies should be necessary for defining the effects of investigated genes on related traits in KM and Kivircik sheep in terms of polymorphic genes specified.Publication Beef colour defined based on ph in holstein bull carcasses(Agricultural Research Communication Centre, 2019-11-01) ARDIÇLI, SENA; DİNÇEL, DENİZ; Balci, Faruk; BALCI, ÖMER FARUK; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Genetik Anabilim Dalı.; 0000-0003-2758-5945; 0000-0002-8015-9032; 0000-0003-2382-1330; AAH-6192-2021; O-3394-2019The present study was carried out on 510 Holstein-Fresian bulls and it aimed to evaluate the effects of season, age at slaughter and pH on meat colour characteristics. An additional aim of this analysis was to determine the impact of environmental factors including season and slaughter age on meat pH. A cluster analysis applied to all the colour coordinates divided the samples into six groups according to their ultimate pH. L*, a*, b* and C* values were significantly higher in cattle slaughtered in the winter season. Moreover, a significant effect of age at slaughter on colour coordinates was found with the exception of a* value. Meat from bulls slaughtered at 16/17 months of age was characterized by brighter colour. Among the pH groups, the highest value of L* was found in meat with pH<5.40, whereas, the highest a* and C* in pH 5.415.50. The present results may be useful and indicative for both beef industry and future studies on meat colour.Publication Association of polymorphisms in lipid and energy metabolism-related genes with fattening performance in simmental cattle(Taylor, 2022-12-01) Ardıçlı, Sena; Dincel, Deniz; Samlı, Hale; Şentürk, Nursen; Karalar, Beyza; Ünlü, Sıla; Soyudal, Bahadır; Kubad, Evrim; Balcı, Faruk; ARDIÇLI, SENA; DİNÇEL, DENİZ; ŞAMLI, HALE; Karalar, Beyza; BALCI, ÖMER FARUK; Kubad, Evrim; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Genetik Anabilim Dalı; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Moleküler Biyoloji ve Genetik Bölümü; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı; 0000-0003-2758-5945; 0000-0003-2382-1330; O-3394-2019; HGK-9411-2022; FVW-7687-2022; HLO-1002-2023; HLO-4495-2023Lipid and energy metabolism are major constituents of mammal growth and thus fattening performance of cattle. This study was designed to evaluate the effects of polymorphisms in lipid and energy metabolism-related genes including oxidized low-density lipoprotein receptor 1 (OLR1), lactoferrin (LTF), stearoyl-CoA desaturase (SCD), beta-lactoglobulin (LGB), thyroglobulin (TG), annexin A9 (ANXA9), myogenic factor 5 (MYF5), protein kinase AMP-activated non-catalytic subunit gamma 3 (PRKAG3), and pituitary-specific transcriptional factor 1 (PIT1), on fattening performance in Simmental cattle. A total of 72 purebred Simmental bulls with a similar initial age and weight were fattened on the same farm for 10 months. Association analysis was performed using linear mixed models. The OLR1 marker was significantly associated with the final weight (FW), hot carcass weight (HCW), chilled carcass weight (CCW), dressing percentage (DP), and total weight gain (TWG). SCD affected the FW, TWG, and average daily live weight gain (ADWG). The present results clearly demonstrated the significant impact of the TG marker on fattening performance. It was highly significantly associated with the FW, HCW, CCW, and TWG. The SCD x TG and the OLR1 x TG interactions had remarkable effects on the traits analyzed. The GACC and CCCC haplotypes of the SCD x TG and OLR1 x TG, respectively, were found to be powerful markers for fattening performance in Simmentals. Novel associations in this study may be useful for further genetic evaluations to improve beef cattle breeding.
