Item The effect of body weight on some welfare indicators in feedlot cattle in a hot environment(Springer, 2012-03) Dikmen, Serdal; Üstüner, Hakan; Orman, Abdulkadir; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Bilimleri Anabilim Dalı.; 0000-0002-5611-4993; 0000-0002-4341-5842; 0000-0001-9138-4422; A-5731-2018; AAG-9127-2021; AAG-9134-2021; 8280302600; 16065222700; 24335834100Heat stress has important effects on the welfare of livestock. The effects of heat stress in cattle include changes in biological functions and behaviors. The aim of this study was to investigate the behavioral differences between light and heavy feedlot cattle reared in a hot environment. Sixteen male Holstein feedlot cattle were allocated to light (353.8 +/- 15.5 kg, n = 8) and heavy (737.1 +/- 15.8 kg, n = 8) groups according to their live weight and were kept in a semi-open feedlot barn. The individual behavioral response variables measured were standing, lying, feeding, drinking, ruminating, locomotor activity and elimination (urinating and defecating). The effects of group, day, observation time, replicate and all interactions were included in an explanatory statistical (GLM) model. The data were analyzed using the PROC GLM procedure of SAS. Overall, the heavy cattle spent more time standing (P < 0.001), lying (P < 0.001), and eliminating (P < 0.05) compared to the light group. In contrast, the light group spent more time eating, drinking and ruminating (P < 0.001). Locomotor activity did not differ significantly between groups (P > 0.05). During the day, heavy cattle spent more time standing (at 1600 hours) and less time eating in comparison with the light cattle (P < 0.001) (at 1300 and 1600 hours). Light and heavy feedlot cattle behaved differently in a hot environment. The findings of the study indicate that the welfare of the heavy Holstein feedlot cattle was impacted negatively when the ambient temperature was high (at 1300 hours).Item The effect of ovulatory follicle size at the time of insemination on pregnancy rate in lactating dairy cows(TÜBİTAK, 2015-09-28) Okut, Hayrettin; Keskin, Abdulkadir; Mecitoğlu, Gülnaz; Bilen, Ebru; Güner, Barış; Orman, Abdulkadir; Gümen, Ahmet; Uludağ Üniversitesi/Veteriner Fakültesi/Jinekoloji ve Doğum Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim Dalı.; 0000-0001-9138-4422; 0000-0003-2817-3221; AAG-9134-2021; AAG-4440-2019; AAH-1406-2021; AAH-3831-2021; 24473229800; 36457964000; 57040965000; 57188841418; 24335834100; 6602393069The aims of this study were to determine the factors that affect follicle size at the time of artificial insemination (AI) and to detect the relationship between ovulatory follicle size at the time of AI and pregnancy rate in dairy cows. A total of 1428 follicle size measurements were obtained from Holstein-Friesian (HF) and Swedish Red (SR) cows that were inseminated with the fixed-timed AI protocols used in this study. Follicle size was affected by breed (P - 0.0001), milk production (P - 0.01), parity (P - 0.05), and season (P = 0.04). Follicle size was greater (P = 0.0001) in the HF (15.55 mm) than the SR cows (14.88 mm). Multiparous cows had larger (P = 0.04) follicles (15.35 mm) than the primiparous cows (15.07 mm). Cows with follicle sizes between 13.5 and 17.5 mm were more likely to be pregnant than cows with other sizes follicles (P < 0.01). Embryonic loss was lower (P < 0.01) in cows with follicle sizes between 13.5 and 16.5 mm. Thus, the follicle size was affected by breed, milk production, parity, and season. Pregnancy and embryonic loss in lactating dairy cows were significantly related to follicle size.Item Effects of a combination of dietary organic acid blend and oregano essential oil (lunacompacid® herbex dry) on the performance and clostridium perfringens proliferation in the ileum of broiler chickens(Uludağ Üniversitesi, 2014-06-24) Çelikbilek, Arzu; Deniz, Gülay; Orman, Abdulkadir; Gençoglu, Hıdır; Kara, Çagdaş; Uludağ Üniversitesi/Veteriner Fakültesi.The aim of the study was to determine the effects of dietary organic acid blend (OAB) and oregano essential oil (OEO) combination (Lunacompacid® Herbex Dry) on the performance and Cp count in the ileum of broiler chickens, and establish connections between performance and Cp proliferation. A total of 200 one day-old Avian Farm male broiler chicks were randomly divided into 2 equal groups (not supplemented control and birds receiving dietary addition of Lunacompacid® Herbex Dry (2g/kg of food) for 6 weeks. Body weights, body weight gains, food intake and food efficiency were weekly evaluated in the present study. Hot carcass weight and yield, and the ileum Ph and Cp count in the ileum content of broiler chickens were determined at the end of the experiment. In the present study, the combination of dietary OAB and OEO significantly decreased ileum pH (P<0.05) and Cp count (P<0.001) in the ileum content, but did not influence growth and carcass performance of broiler chickens. It was concluded that the lack of significant effects on broiler performance could be related to ideal rearing condition of our experiment. It is possible that the use of OAB and OEO combination in diets of broiler housed under suboptimal conditions may keep down Cp proliferation in the chicken gut and therefore may improve performance in this way.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; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Gıda Hijyeni ve Teknolojisi Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim 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).Item Effects of calcium propionate by different numbers of applications in first week postpartum of dairy cows on hypocalcemia, milk production and reproductive disorders(Taylor & Francis, 2009) Kara, Çağdaş; Orman, Abdulkadir; Udum, Duygu; Yavuz, H. Melih; Kovanlıkaya, Arda; Uludağ Üniversitesi/Veterinerlik Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Veterinerlik Fakültesi/Zootekni Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Biyokimya Anabilim Dalı.; 0000-0001-7052-1694; 0000-0001-9138-4422; AAH-5167-2021; AAG-9134-2021; 31967678500; 24335834100; 31967936400; 31967662500; 31967682500This study was conducted to evaluate effects of calcium propionate on hypocalcemia, dry matter intake, body condition score, milk production and reproductive disorders in dairy cows. Twenty four multiparous Holstein cows were sorted by parity, body condition score (BCS) in close-up period and season of calving and assigned to one of the three treatments. The cows in treatment 1 (T1) received two drenches at calving and 24h after calving. The cows in treatment 2 (T2) received three drenches at calving, 24h after calving and 7 days after calving. The cows in treatment 3 (T3) were the control. Each drench contained 143g of calcium as calcium propionate (0.68kg). Parameters studied were serum calcium, glucose and nonesterified fatty acid (NEFA) concentrations, dry matter intake (DMI), BCS, milk production (MP), incidence of retained placenta (RP) and metritis. Milk fever developed in 5 of 8 cows, in 3 of 8 cows and in 3 of 8 cows in T1, T2 and T3, respectively, at calving. There was no cow with milk fever in T1 and T2 at 4h after second drench (about 28h after calving) but 3 of 8 cows in T3 had still milk fever at this time. The cows receiving two drenches recovered from milk fever in a shorter term as compared to the cows in T3. There were no differences among treatments for DMI, BCS, MP, RP, serum glucose and NEFA concentrations during the experimental period. There was no difference for metritis between T1 and T3 but incidence of metritis in T2 was significantly lower as compared to T3 (P<0.05). Two drenches of calcium propionate were beneficial in treating milk fever and three drenches of calcium propionate were considered to have had a preventive effect for metritis.Item Effects of glucosinolates and their hydrolysis products on biochemical and performance parameters in broiler chicken diets(Indian Council of Agricultural Research, 2016-03-16) Berhow, Mark Alan; Belenli, Deniz; Polat, Ümit; Orman, Abdulkadir; Yesilbağ, Derya; Berhow, Mark A.; Uludağ Üniversitesi/Veteriner Fakültesi/Biyokimya Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvancılık Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.; 0000-0001-9138-4422; AAG-9134-2021; AAK-5370-2020; 56743270100; 56235316900; 24335834100; 9246817500; 7003305843Glucosinolates are important bioactive molecules and widely found in Brassicaceae species (cress, brussels sprouts, mustard, broccoli, kale etc.). Depending on the amount of these vegetables consumed, both positive and negative metabolic effects from glucosinolate metabolites may occur. The aim of this study was to investigate inexpensive animal food sources that both increase weight gain and provide enhanced performance parameters without adversely affecting the animal's health and metabolism; to evaluate dose adjustment of food containing glucosinolates in animals; and to evaluate changes in the biochemical and performance status of chickens on the glucosinolate containing diets. Day-old Ross 308 broiler line chicks (624) were divided into 1 control and 3 treatment groups. Cress seed (Lepidium sativum) was added 0.05% for the first treatment group (group 1, 10g/kg), 0.10% for the second treatment group (group 2, 20g/kg) and 0.15% for the last treatment groups (group 3, 30 g/kg) to the diet. Serum samples were evaluated for serum glucose, adiponectin, leptin, growth hormone, estradiol and cortisol levels. Feed intake, live body weight gain and feed conversion ratio were investigated for performance parameters. The results showed that dietary cress seed supplementation as feed additive (10, 20 and 30 g/kg) did not significantly improve the dietary performance, or carcass parameters of broiler chickens. Feed intake was the highest in group 2 (20g/kg), female live weight was the highest in group 2 (20 g/kg) and 3 (30 g/kg).Item Effects of initial fattening age on carcass characteristics and meat quality in Simmental bulls imported from Austria to Turkey(South African Journal of Animal Sciences, 2017-02-07) Yalçıntan, Hülya; Ekiz, Bülent; Kandazoğlu, O.; Üstüner, Hakan; Orman, Abdulkadir; Ardıçlı, Sena; Gençoğlu, Hıdır; Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Genetik Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.; 0000-0002-4341-5842; 0000-0001-9138-4422; 0000-0003-2758-5945; AAG-9127-2021; AAG-9134-2021; O-3394-2019; HJZ-4775-2023The aim of this study was to determine the effects of initial fattening age on carcass and meat quality of Simmental bulls imported from Austria to Turkey. These animals were allocated to two initial ages of fattening groups, namely young (n = 74) and old group (n = 61) at 5.5 and 7.5 months old, respectively. After reaching the target final weights, the animals were slaughtered and the carcass characteristics, area and circumference of the longissimus thoracis et lumborum (LTL) muscle, marbling score, and meat quality, including cooking loss, water-holding capacity (WHC), shear force (WBSF), and colour parameters were evaluated in six animals per group. A comparison of hot and cold carcass weights and dressing percentages, LTL circumference, fat thickness values and marbling score indicated no significant differences between young and old groups. However, the LTL area was significantly affected by the initial age. There were no significant differences between groups in WHC, cooking loss, and WBSF values and meat colour parameters. The results of this study showed that the initial fattening age of bulls showed no significant effect on carcass and meat quality parameters, except the LTL area. The LTL area was significantly higher in young group than the old group. Further studies are needed to improve carcass and meat quality of imported Simmental bulls through modifying the initial fattening age.Item The effects of supplemental saccharomyces cerevisiae and phytase on growth performances and plasma biochemical parameters of broiler chickens(Uludağ Üniversitesi, 2015-03-20) Suzer, Bayram; Altınbaş, Burçin; Seyidoğlu, Nilay; Arıcan, İlker; Orman, Abdulkadir; Yıldız, Hüseyin; Yalçın, Murat; Uludağ Üniversitesi/Veteriner Fakültesi.Saccharomyces cerevisiae and phytase can be used as a feed supplement in combination or alone for broiler feeding. An experiment was performed to study the effect of supplemental different ratio S. cerevisiae and phytase combination on growth performances, plasma biochemical parameters and plasma enzyme activities of broiler chickens. Animal were feed ad libitum through the study. Sixty hundred 1 day-old broiler chicks were randomly selected and distributed into eight groups as control (C); phytase (P) (added 200 g Pyhase to 1000 kg of diet); S. cerevisiae (Y1) (added 0.1% S. cerevisiae of the diet); Y1+P (combination of group Y1 and P); S. cerevisiae (Y2) (added 0.2% S. cerevisiae of the diet); Y2+P (Combination of Y2 and P); Y4 (added 0.4% S. cerevisiae of the diet); Y4+P (Combination of Y4 and P) respectively. At the end of the study, blood samples were collected from 15 randomly selected broiler chickens from each group through the brachial vein on the 42nd day of the experiment. Plasma were separated and used for measurement of plasma biochemical parameters and enzyme activities. S.cerevisiae alone and combination of Phytase and S. cerevisiae increased body weight and body weight gain of broiler, especially in 6th week, except in group Y4. Although, the broiler chickens supplemented with just phytase or/and S. cerevisiae and their combination had lower plasma triglyceride, total cholesterol, LDL-cholesterol, glucose, calcium and GGT enzyme activity , they had higher HDL-cholesterol, phosphorus and ALT enzyme. Moreover, supplementation with just phytase or/and S. cerevisiae and their combination did not change the hematocrit, plasma total protein and AST enzyme levels of the broiler chickens. These results demonstrated that phytase and S. cerevisiae alone or/and their combination improved growth performance and body weight gain of the broiler chickens. So, S.cerevisiae and phytase combination may be used as an growth enhancer. However, more studies would be necessary to obtain the effects of supplementing yeast and phytase combination on growth.Item Effects of supplementary nutrition in awassi ewes on sexual behaviors and reproductive traits(Uludağ Üniversitesi, 2010) Kara, Çağdaş; Orman, Abdulkadir; Topal, Ersin; Çarkungöz, Ender; Uludağ Üniversitesi/Veteriner Fakültesi.The present study was conducted to improve sexual behavior in Awassi ewes by the nutritional supplement containing multiple nutrients, such as vitamins, minerals, amino acids and sorbitol. In addition, the purpose of this study was to evaluate the effect of this nutritional supplement on litter size in ewes and birth weight of lambs. Twenty six Awassi ewes (50 ± 3.20 kg), aged 2 to 4 years, and three sexually experienced Awassi rams (90 ± 5.30 kg), aged 3 years, were used. The ewes were sorted by age, body weight and litter size of them in previous years and assigned to one of the two groups (experimental; EG and control; CG). Each group consisted of 13 ewes. The daily ration of the ewes in EG was added 30 g/ewe the nutritional supplement for 5 days before mating period and 5 days during last month of gestation. Despite the fact that there were no statistically differences for sexual behaviors, the number of lambs born, lambing percentage and birth weights of lambs between groups (p > 0.05), our results showed that the combination of nutrients improving animal health and reproduction had a positive effect on embryonic survival, litter size and birth weight.Item Ensuring the reproduction of gazelles, whose numbers are decreasing in Türkiye and whose habitats are confined to a narrow region, in new habitats(Bursa Uludağ Üniversitesi, 2022-11-30) Uztemur, Adil; Orman, Abdulkadir; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim Dalı.; 0000-0001-9138-4422The aim of this study was to resettle Gazella Marica, whose habitats are declining in Türkiye, to the foothills of Cudi Mountain, which is connected to the Silopi District of Şırnak Province, which was previously located within the natural habitat zone. The gazelles obtained from the 75th Year Gazelle Production Station were placed in individual crates of 100x36x90 cm made of plywood, with 51 numbers (24 females, 27 males) gazelles in 2020 and 40 numbers (19 females and 21 males) in 2021. Mass releases were made with a ceremony in an area with similar climatic characteristics, which is approximately 380 km away. 1 gazelle died in 2020, 6 gazelles died in 2021. During the post-release monitoring activities, the first reproduction records of gazelles released in 2020 were successfully recorded in 2021 and 23 new individuals were obtained. The current number of individuals reached 106. It has been observed that gazelles have adapted to the area in the 2 years. Illegal hunting is prevented as the region is within the borders of military security. Monitoring studies continue for the long-term management plan.Publication Evaluation of glutaraldehyde coagulation test and colostrum brix refractometer compared with snap foal igg test in neonatal foals(Wiley, 2023-10-01) Babaeski, Serdar; Kasap, Sevim; KENNERMAN, ENGİN; KASAP, SEVİM; Kennerman, Engin; ORMAN, ABDÜLKADİR; Orman, Abdulkadir; TEMİZEL, ETHEM MUTLU; Yıldırım, Kübra Nur; YILDIRIM, KÜBRA NUR; Bursa Uludağ Üniversitesi/Veteriner Fakültesi; 0000-0001-9138-4422; AAG-9134-2021Background: Prompt diagnosis of passive transfer failure in the neonatal period is important for early treatment.Objectives: To compare the diagnostic performance of serum glutaraldehyde coagulation test (GCT) and colostrum BRIX% for failure to transfer passive immunity (FTPI) diagnosis with the results of SNAP foal test and to evaluate the results of serum GCT and colostrum BRIX% measurements in foals with diarrhoea in the 0-1 month period.Study design: In vitro experiments.Methods: Excess serum and colostrum (n: 298) from samples collected from newborn foals and their dams for clinical purposes were used. 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.Item Kuzularda besi başı ağırlığının besi performansına ve besi ekonomisine etkisi(Uludağ Üniversitesi, 1999-10-19) Oğan, Mustafa; Başpınar, Hasan; Eren, Mustafa; Orman, Abdulkadir; Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastanesi Anabilim Dalı.Bu araştırma kuzularda besi başlangıç ağırlığının besi performansına etkisini ve en ekonomik besi başı ağırlığını tespit etmek amacı ile yapılmıştır. Çalışınanın materyalini 58 baş erkek kuzu oluşturmuştur. Hayvanlar besi başlangıcında üç canlı ağırlık grubuna ayrılmışlardır. Gruplara 20, 19 ve 19 baş hayvan konulmuştur. I. grubun ortalama besi başı ağırlığı 24.72 kg, II. grubun 28.01 kg ve lll. grubun ise 31.16 kg olmuştur. tüm gruplar 43 kg canlı ağırlıkta kesilmiştir. Besi süresi gruplarda sırası ile 68.80, 59.47 ve 47.00 gün olarak gerçekleşmiştir. Günlük ortalama canlı ağırlık artışı gruplarda, sırası ile; 274.68, 274,66 ve 277.75 g bulunmuştur. Gruplar arası farklar istatistiki bakımdan önemsiz çıkmıştır. Bir kilogram canlı ağırlık artışı için tüketilen kuru madde miktarı sırası ile 6.39, 6.90 ve 6.74 kg olarak tespit edilmiştir. Bütün gruplarda marjinal gelir-gider farkı pozitif çıkmış olup en büyük fark birinci grupta hesaplanmıştır. Çalışılan gruplar arasında en uygun besi başı canlı ağırlığın 24.72 kg olduğu sonucuna varılmıştır.Item Use of thermal imaging for identification of foot lesions in dairy cattle(Taylor & Francis, 2016-04-13) Endres, Marcia; Orman, Abdulkadir; Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim Dalı.; 0000-0001-9138-4422; AAG-9134-2021; 24335834100The objective of this study was to investigate the use of infrared thermography (IRT) for detection of foot lesions in dairy cattle. Thermal images of the rear feet of 139 lactating dairy cows were taken with a thermal camera and evaluated using imaging software. Foot lesions identified in the study included white line disease (WLD), sole ulcer (SU) and digital dermatitis (DD). Temperatures at the coronary band (CBT) and the skin (ST) were recorded. Cows were scored for locomotion on a scale of 1-5 (1=normal and 5=severely lame). CBT was higher for all types of foot lesion (34.1 +/- 2.3, 33.8 +/- 1.6 and 33.1 +/- 1.6 degrees C for WLD, SU and DD, respectively) than for healthy (32.6 +/- 1.9 degrees C) feet. ST was higher only for WLD (33.2 +/- 2.0 degrees C) compared to healthy feet (31.5 +/- 1.7 degrees C). T (temperature difference between CBT and ST) was higher for SU (2.1 +/- 0.8 degrees C) than healthy feet (1.1 +/- 0.9 degrees C). Locomotion scores (LSs) were similar between healthy cows (2.2 +/- 0.7) and DD (2.4 +/- 0.7) but greater for SU and WLD cows (3.0 +/- 0.9, 3.0 +/- 0.8) than healthy cows. The threshold values established for CBT and ST were 33.5 degrees C (sensitivity=77.8%, specificity=65.2%) and 33.7 degrees C (sensitivity=44.4%, specificity=92.9%) for SU, and 34.4(o)C (sensitivity=28.1%, specificity=88.6%) and 31.8 degrees C (sensitivity=60.7%, specificity=55.4%) for overall lesion, respectively. These results indicate that IRT can be a useful tool for detection of SU, but not WLD and DD. In addition, CBT and T were the best indicators for the detection of foot lesions.Item Yemde kurutulmuş rumen içeriği kullanmanın broyler verimi üzerine etkileri(Uludağ Üniversitesi, 2000-02-03) Petek, Metin; Başpınar, Hasan; Oğan, Mustafa; Orman, Abdulkadir; Yaman, Salih; Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim Dalı.Bu çalışma rasyona ilave edilen kurutulmuş rumen içeriğinin broyler verimine etkilerini saptamak amacıyla yapılmıştır. Kontrol grubunda yer alan piliçler deneme süresince broyler başlangıç yemi ile, II ve III. gruplarda yer alan piliçler ise deneme süresince aynı yeme % 10 ve % 20 kurutulmuş rumen içeriği ilave edilen yem ile beslenmişlerdir. Canlı ağırlık, yemden yararlanma oranı ile karkas, taşlık ve karaciğer ağırlıklarının canlı ağırlık içindeki payı bakımından gruplar arasında gözlemlenen farklılıklar önemli bulunmuştur (P<0.001, P<0.01 , P<0.05, P<0.001, P<0.05). Kontrol grubunun Avrupa verimlilik Faktörü en yüksek olmasına rağmen, % 10 ve % 20 kurutulmuş rumen içeriği ile beslenen deneme gruplarının ekonomik verimliliği kontrol grubundan daha yüksek bulunmuştur. Bu çalışmada broyler yemine ilave edilen kurutulmuş rumen içeriğinin broyler verimini etkilemeksizin ekonomik olarak broyler beslemede kullanılabileceği sonucuna varılmıştır.
