Publication Effects of gender and slaughter age on meat quality of anatolian water buffaloes(Springer, 2021-09-01) Turan, Adem; Yalçıntan, Hülya; Orman, Abdülkadir; Ekiz, Bülent; Turan, Adem; ORMAN, ABDÜLKADİR; 0000-0001-7062-1521; 0000-0001-9138-4422; 0000-0001-6458-5747; ABD-8329-2021; D-1711-2011; D-4671-2019; AAG-9134-2021The study aimed to investigate the effects of slaughter age and gender on specific carcass and technological meat quality characteristics in Anatolian water buffaloes. The study was conducted on 55 water buffaloes using a 2 x 2 factorial design with two independent variables at two levels. Gender subgroups of male (n = 29) and female (n = 26) and slaughter age subgroups of younger than 2 years of age (n = 29) and older than 2 years of age (n = 26) were evaluated. Hot carcass and cold carcass weights were higher in old water buffaloes than young ones (P < 0.001). The skin weight of old buffaloes was also higher than young buffaloes (P < 0.01). Drip loss, expressed juice, and Warner Bratzler (WB) shear force values of longissimus dorsi (LD) muscles were not influenced by age group and gender of buffaloes. The lightness (L*) and hue (H*) values were higher in young buffaloes than old animals (P < 0.001). The meat of male buffaloes had lower redness (a*) and chroma (C*) values than that of female buffaloes. The current results indicated that female water buffalo could also be used for meat production away from negative impressions on the meat quality of female water buffalo.Publication Effects of exogenous amylase in transition dairy cows fed low-starch diets: 1. lactation performance(Kafkas Üniversitesi, 2019-07-01) Gençoğlu, Hıdır; Kara, Çağdaş; Efil, Mukaddes Merve; Orman, Abdülkadir; Meral, Yavuz; Kovanlıkaya, Elif; Çetin, İsmail; Shaver, Randy Duncan; Şen, Erkan; Altaş, Tolga; GENÇOĞLU, HIDIR; KARA, ÇAĞDAŞ; Efil, Mukaddes Merve; ORMAN, ABDÜLKADİR; Kovanlıkaya, Elif; ŞEN, ERKAN; Altaş, Tolga; Veteriner Fakültesi; Zootekni Ana Bilim Dalı; 0000-0001-9451-4587 ; HJZ-4775-2023; AAG-9134-2021; DXJ-9465-2022; ESL-6788-2022; FCS-6469-2022; KHZ-5460-2024; EMV-1288-2022The objective of this trial was to determine the effect of exogenous amylase during the transition period in dairy cows on dry matter intake and lactation performance. The effect of exogenous amylase supplementation on lactation diets with low starch concentration (19.5% of dry matter) and dry period diets with moderate starch concentration (15.5% of dry matter) was evaluated. A total of 30 multiparus Holstein cows were randomly assigned to two groups fed diets with (n=15) or without amylase (n=15). Treatments were granular amylase (0.5 g of Ronozyme RumiStar per kg of total mixed ration dry matter) or control. The research was conducted starting at 21 d prepartum until 84 d postpartum. Starch and neutral detergent fiber concentrations averaged 15.5 +/- 0.5% and 15.7 +/- 0.9%, 42.6 +/- 1.1% and 43.4 +/- 1.2% in close up diets and 19.8 +/- 2.9% and 19.4 +/- 0.5%, 33.6 +/- 0.8% and 34.2 +/- 0.6% in lactation diets for control and amylase, respectively. Dry matter intake, milk yield and composition were evaluated for differences between treatments. Postpartum intakes of dry matter (DMI) and organic matter (OM), neutral detergent fiber (NDF), crude protein (CP), and starch intake were unaffected by treatment. Milk yield was not influenced by treatment, but numerically greater by 2.0 kg/d for cows fed amylase compared with control diet. The percentages of milk fat, protein and lactose were not impressed by treatment, however fat-, solid-, and energy-corrected milk were 2 kg/d greater for cows fed amylase diet than for cows fed control diet. Fat-, solid-, and energy-corrected milk feed conversions (kg/kg DMI) were 5 to 6% greater for cows fed amylase diet than for cows fed control diet (P< 0.01). It was concluded that inclusion of amylase improved the feed efficiency of lactating cows fed a low starch diet, may offer for potential to increase milk yield; but the enzyme did not affect DMI.Publication Environmental factors affecting milk and milk fat yields of holstein cows(Indian Veterinary Journal, 2008-06-01) Orman, Abdülkadir; Oğan, M. Mustafa; ORMAN, ABDÜLKADİR; OĞAN, MEHMET MUSTAFA; Veteriner Fakültesi; Zootekni Ana Bilim Dalı; 0000-0001-9138-4422; AAG-9134-2021; DKK-1988-2022Publication Effects of daily propylene glycol drenching during the Ovsynch protocol on fertility and metabolic parameters in lactating dairy cows(Wiley, 2023-06-18) Çakırcalı, Rabia; Karakaya-Bilen, Ebru; Güner, Barış; Mecitoğlu, Zafer; Ortaç, Cihan Tolga; Keskin, Abdulkadir; Orman, Abdulkadir; Gümen, Ahmet; Çakirçalı, Rabia; MECİTOĞLU, ZAFER; Ortaç, Cihan Tolga; KESKİN, ABDULKADİR; ORMAN, ABDÜLKADİR; GÜMEN, AHMET; Veteriner Fakültesi; Jinekoloji Ana Bilim Dalı; 0000-0001-9138-4422 ; 0000-0002-5557-121X ; DWK-3046-2022; AAH-1677-2021; JLZ-4927-2023; AAH-3831-2021; AAG-9134-2021; AAH-1406-2021Negative energy balance (NEB) caused by restricted feed intake leads to body condition loss (BCS), increased metabolic stress and reduced fertility in dairy cows. Propylene glycol (PG) is a precursor of ruminal propionate for gluconeogenesis used to increase metabolic adaptation to the early postpartum period. The aim of this study was to determine the effects of daily drenching of PG during the fixed-time artificial insemination (FTAI) protocol on beta-hydroxybutyric acid (BHBA), glucose, adiponectin, insulin-like growth factor-1 (IGF1) concentrations, follicle size and pregnancy rate in dairy cows. Cows (n = 148) were randomly divided into two groups and received either 300 mL of PG (PG-OVS, n = 76) or 300 mL of water (CON- -OVS, n = 72) each day of the Ovsynch protocol (GnRH-7 days-PGF2a-56 hours-GnRH-16-18-hour FTAI) between days 57 +/- 3 to 67 +/- 3 postpartum for the first service. Body condition scores (14 days before expected calving, at calving, on days 21 and 42 postpartum) were recorded. Blood samples were collected days 7 +/- 3, 21 +/- 3 postpartum, at the beginning of the Ovsynch (days 57 +/- 3) and at the time of FTAI (days 67 +/- 3) for measurements of BHBA, glucose, adiponectin and IGF1 concentrations. Ultrasonographic examinations were done to measure follicle size at the beginning of Ovsynch and FTAI and to determine pregnancy on days 30 and 60 following FTAI. There were no differences (p >.05) in glucose, adiponectin and IGF1 concentrations between the groups during the study. Although there was no difference ( p >.05) in BHBA concentrations on postpartum day 7 +/- 3, 21 +/- 3 and 57 +/- 3 between the groups, BHBA concentrations at the time of insemination was lower (p <.05) in the PG-OVS group (0.72 +/- 0.03 mmol/L) than in the CON-OVS group (0.81 +/- 0.03 mmol/L). Follicle sizes at the beginning of Ovsynch (PG-OVS, 14.5 +/- 0.48 mm; CON-OVS, 14.3 +/- 0.59 mm) and FTAI (PG-OVS, 17.8 +/- 0.52 mm; CON-OVS, 17.7 +/- 0.42 mm) were not different ( p <.05). Pregnancy rate of the cows in the PG-OVS group (46.1%, 35/76) was higher (p =.05) than in the CON-OVS group (30.6%, 22/72) on day 30 following FTAI. In conclusion, decreasing serum BHBA concentrations at the time of FTAI by means of daily drenching of PG during the Ovsynch protocol, increased the pregnancy rate at first service in lactating dairy cows. On the other hand, blood glucose was not related with pregnancy rates in our study, probably as a result of our sampling time and more rapid fluctuations of blood glucose concentrations when compared to BHBA.Publication Chick quality assesment: Visual scoring or chick length?(Elsevier, 2008-01-01) Petek, Metin; Orman, Abdulkadir; Alpay, Fazlı; Dikmen, Serdal; PETEK, METİN; ORMAN, ABDÜLKADİR; ALPAY, FAZLI; DİKMEN, SERDAL; Uludağ Üniversitesi; 0000-0001-9138-4422; 0000-0002-5611-4993; A-5731-2018; JPK-5654-2023; AAG-9134-2021; AAE-4562-2019Publication What is the best first-calving age of cows in robotic milking farms?(Taylor & Francis Ltd, 2022-12-31) İlhan, Gürkan; Çavuşoğlu, Enver; Orman, Abdulkadir; İlhan, Gürkan; ÇAVUŞOĞLU, ENVER; ORMAN, ABDÜLKADİR; Sağlık Bilimleri Enstitüsü; Hayvan Bilimleri Ana Bilim Dalı; 0000-0002-9018-3511; 0000-0001-9138-4422; ABE-4828-2020; AAG-9134-2021; CWG-8158-2022The aim of this study is to determine the effect of first-calving age (FCA) on yield parameters and productive life in dairy farms using a robotic milking system in Turkey. The cows (n = 1579) were divided into five groups (24, 25, 26, 27, 28 months and above FCA. The average milk yield was highest in 24 months of FCA (9140.31 +/- 145.55 kg) and was lowest in 27 months of FCA (8534.55 +/- 131.00 kg) (p < .05). The average service period length in the first lactation was longer in cows of 28 months old (158.92 +/- 7.28 days) than 26 and 27 months (131.96 +/- 4.45and 130.51 +/- 54.97 days respectively) old groups (p < .05). A number of lactations of cows that were 26 months old (2.52 +/- 0.09) at FCA was higher than those FCA was 24 months and 28 months (2.03 +/- 0.15 and 2.18 +/- 0.09 respectively) (p < .05). Replacement rates were not differing statistically at different lactations. The most frequent reasons for culling were mastitis and reproduction in all groups. As a result, cows in 24 months of FCA had no undesirable results in terms of milk yield, service period, number of insemination per lactation.Publication Butaphosphan and cyanocobalamin treatment of pregnant ewes: Metabolic effects and potential prophylactic effect for pregnancy toxaemia(Elsevier, 2015-04-01) Temizel, Ethem Mutlu; Batmaz, Hasan; Keskin, Abdülkadir; Orman, Abdülkadir; Gençoğlu, Hıdır; Çatık, Serkan; Topal, Onur; TEMİZEL, ETHEM MUTLU; BATMAZ, HASAN; KESKİN, ABDULKADİR; ORMAN, ABDÜLKADİR; GENÇOĞLU, HIDIR; Çatık, Serkan; TOPAL, ONUR; Veteriner Fakültesi; İç Hastalıkları Ana Bilim Dalı; 0000-0001-9138-4422; 0000-0002-1933-7354; 0000-0003-1991-8957; HJZ-4775-2023; AAH-1712-2021; AAH-3831-2021; AAG-9134-2021; S-8278-2017; ECV-4083-2022; CHM-0716-2022The effect of administration of butaphosphan and cyanocobalamin on the prophylaxis of pregnancy toxaemia in ewe was investigated. Moreover, the effects of these compounds on body weight gain and biochemical metabolism of pregnant ewe was assessed. A total of 59 pregnant Kivircik crossbred ewes were used in this study. Group I (n: 15) was administered butaphosphan and cyanocobalamin three times before delivery at 1-week intervals. Group II (n: 15) was administered butaphosphan and cyanocobalamin three times before delivery at 3-day intervals. Group III (n: 15) was administered 0.9% NaCl three times before delivery at 1-week intervals. Group IV (n: 14) was administered 0.9%NaCI three times before delivery at 3-day intervals. Six blood samples Were taken from each ewe four times before delivery and two times after delivery. Haematological and biochemical analyses were performed.The levels of BHB and NEFA in groups administered butaphosphan and cyanocobalamin were noticeably lower but there were no statistically significance. Elevated BHB (>0.8 mmol/L), subclinical pregnancies toxaemia were identified in 56.66% in test groups and 72.41% in control groups in all ewes and this was higher in the ewes bearing multiple pregnancies 71.42 in test groups and 82.35% in control groups. Subclinical pregnancy toxaemia in pregnant ewes with twins or triplets is lower than the levels for the control groups, despite the greater lamb counts and weights of the ewes in test groups.Based on our results, it was concluded that the butaphosphan and cyanocobalamin combination could be used as an alternative treatment for the prevention of pregnancy toxaemia.

Foals were classified as FTPI positive (IgG < 8 g/L) or negative (IgG >= 8 g/L) using the SNAP foal test. We compared the sensitivity and specificity of serum GCT and colostrum BRIX % for diagnosing FTPI in all foals and in the sub-group of foals which developed diarrhoea within the first month of life was noted. The relationships between the results of the serum GCT and colostrum BRIX% and diarrhoea in foals with and without FTPI were evaluated.Results: Serum GCT and colostrum BRIX % were statistically significantly different (p < 0.05) between the foals without FTPI and with FTPI classified according to the SNAP test. Using a cut-off value for serum GCT of >10, sensitivity was 100% (95% CI 92.9%-100%) and specificity 100% (98.3%-100%) while with a cut-off value of <= 24, with colostrum BRIX% of <= 24 sensitivity was 92% (80.9%-97.8%), and specificity was 98% (95.3-99.3). In the sub-group of foals without FTPI using a colostrum BRIX% cut-off value of <= 26 the sensitivity for prediction of diarrhoea in the 0-1 month period was only 72.4% (52.8-87.3, p < 0.001) with specificity 54.3% (47.6-61.1) but the test performance was not robust (ROC AUC 0.61).Main limitations: The number of repeated measurements in the evaluation of serum GCT, and colostrum BRIX% was low. More clinical problems could be examined.Conclusions: The serum GCT, and colostrum BRIX%, both economical and practical to use in the field, gave results comparable with the SNAP foal IgG test. The ability to accurately predict diarrhoea in the first month of life with these tests was limited.Publication Effects of a short-term supplementation with liquid oligofructose-enriched inulin on faecal characteristics and selected serum metabolites of healthy saanen kids(Kafkas Üniversitesi, 2015-09-01) Kara, Cağdaş; Meral, Yavuz; Yibar, Artun; Biricik, Hakan; Orman, Abdulkadir; Deniz, Gülay; Yeşilbağ, Derya; Çetin, İsmail; Gençoğlu, Hıdır; Türkmen, İsmet; KARA, ÇAĞDAŞ; Meral, Yavuz; YIBAR, ARTUN; BİRİCİK, HAKAN; ORMAN, ABDÜLKADİR; DENİZ, GÜLAY; YEŞİLBAĞ, DERYA; ÇETİN, İSMAİL; GENÇOĞLU, HIDIR; TÜRKMEN, İBRAHİM İSMET; Veteriner Fakültesi; Gıda Hijyeni ve Teknolojisi Ana Bilim Dalı; 0000-0001-7051-1349; 0000-0001-9138-4422; AAH-4032-2021; ABE-9200-2022; AAG-9134-2021; AAK-5370-2020; HJZ-4775-2023; FFA-7187-2022; DGQ-7149-2022; ISX-0239-2023; JIM-4044-2023; EDZ-7334-2022The objective of this study was to evaluate the effects of a short-term supplementation with liquid oligofructose-enriched inulin on faecal characteristics and selected serum metabolites of healthy Saanen kids. Twenty-four kids (44 days of age) were allotted to a control (CG) or an experimental (EG) group. Each group consisted of 12 kids. Each kid in EG was supplemented with 0.8 and 1.6 g/d of oligofructose-enriched inulin from day 1 to 5 and from day 6 to 15, respectively. Liquid oligofructose-enriched inulin supplementation did not affect faecal score and pH (P > 0.05). Faecal acetate, propionate and total SCFA concentrations did not differ (P > 0.05) between CG and EG, whereas faecal butyrate concentration was higher (P< 0.05) in kids supplemented with liquid oligofructose-enriched inulin. Due to trophic and antiinflammatory effects of butyrate, we hypothesize that oligofructose-enriched inulin supplementation may be useful to help tissue repair and regeneration, particularly during an intestinal infection. Faecal Lactobacillus, Bifidobacterium and Clostridium perfringens concentrations were not affected by oligofructose-enriched inulin supplementation (P > 0.05). Daily dose of oligofructose-enriched inulin tended to increase serum glucose concentrations (P < 0.09, P < 0.08). Serum urea and albumin concentrations were similar between groups (P > 0.05). Serum total protein and globulin levels were lower in EG compared with CG (P < 0.05). During the experimental period lasting for 15 days, there were no differences in growth performance parameters between groups (P > 0.05).
