Öğe Degişik Irk Koyunlarda Progesteron+ecg İle Östrusların Senkronize Edilmesi Ve Hayvanlarda Kolesterol İle Progesteron Seviyelerinin Araştırılması(Selçuk Üniversitesi, 2002) Uçar, Mehmet; Gündoğan, Mustafa; Özdemir, Mehmet; Tekerli, Mustafa; Eryavuz, Abdullah; Saban, Erdal; Özenç, ErhanÖzet: Bu çalışmada aşım sezonunda değişik ırk koyunlara senkronizasyon amacıyla florogeston asetat+eCG yapılarak bazı reproduktil parametreler ile gebe hayvanların kolesterol ve progesteron konsantrasyonlan incelendi. Afyon Kocatepe Üni versitesi Araştırma Uygulama Merkezindeki 12 Sakız, 15 Akkaraman, 14 Ivesi ve 18 Dağlıç koyun (n:59) kullanıldı. Hay vanlar rastgele ikiye aynidi ve kontrol grubunda (n:29) bulunanların östruslan arama koçuyla belirlenerek elde aşım yap- binid. Deneme grubuna (n:30) ise 40 mg florogeston asetatlı sünger intravaginal yerleştirilerek 14 gün süreyle bırakıldı Süngerlerin çıkanlacağı gün Sakızlara 500, diğerlerine 600 IU eCG intramuskuler yapıldı. Östruslar arama koçuyla be- Irtenerek, 48-52. saatler arasında elde aşım yaptırıldı. Aynca her iki gruptaki hayvanlardan gebelik öncesi dönemde iki kez, gebeliğin 45., 90. ve 135. günlerinde ve postpartum 10.günde kan alınarak kolesterol ve progesteron seviyeleri araştinidh Deneme ve kontrol gruplannda östrus gözlenme oranı 0.0 olarak belirlenirken, gebelik oranlan bakımından gruplar ve klar arası farklar önemli bulunmadı. Her iki grupta da Sakız ırkının kuzu verimi bakımından diğer irklardan üstün olduğu be- Intendi (p<0.05). Koyunlarda ortalama kolesterol değerleri gebelik öncesinde 67 15+2.35-72 26:2.50 mg/dl, gebeliğin 45 günde 64.86+1.63, 90 günde 50.07+2.07 ve 135.günde 62.69±1.63 mg/dl, postpartum 10.günde ise 46.74±1.06 mg/dl tespit edildi. Progesteronun gebelik öncesinde Sakız ırkında yüksek seviyede olduğu gözlenirken, gebelik ilerledikçe dö- nemler arası progesteron farkdan önemli bulundu (p<0.05). Gebelik öncesi 2.dönem hariç diğer dönemlerde kolesterol ve progesteron arasında pozitif korelasyon olduğu belirlendi. Ayrıca kuzu verimleri ile kolesterol ve progesteron seviyeleri ara- sanda da pozitif bir korelasyon şekillendiği gözlendi. Sonuç olarak aşım mevsiminde porgesteron+eCG uygulamalarının kontrol grubuna göre bir avantaj oluşturmadığı, kolesterol seviyelerinin gebelik dönemi ve kuzu sayısından çok fazla et- kilenmediği, progesteron konsantrasyonun gebelik ilerledikçe kuzu sayısına bağlı olmaksızın yükseldiği, ancak birçok faktörün kolesterol seviyesini etkilemesinden dolayı bu ikili arasında belirlenen pozitif korelasyonun pratikte yararlı bilgiler ver- meyeceği kanaatine varıldı.Öğe Deneysel Hi?perkolesterolemi? Oluşturulan Köpeklerde Bazı Hematoloji?k Parametreler Üzeri?ne Soğan Yağının Etki?si?(Selçuk Üniversitesi, 1995 Ocak) Keskin, Ercan; Durgun, Zafer; Kocabatmaz, Mehmet; Eryavuz, AbdullahEight dogs, 8-10 months aged, were used in the investigation. The dogs were divided into two equal groups as control and experimental. Both groups were fed diet containing 0.2% cholesterol for 16 days. At 10 th. day of this period, plasma cholesterol levels were increased four times to begining of this period in both groups. The increases in cholesterol levels in both groups caused no roughness in erytrocytes surface. After 10 th day of 16 day period, experimental group received daily 50µl of onion oil with 200 g of ground meat additon to cholesterol-supplemented diet whereas control group continued feeding cholesterol-suplemented diet and 200 g of ground meat for six days. At the 5 th. and 6 th. days of period of onion oil administration (15 th. and 16 th. days of total period). Plasma cholesterol levels in experimental group decreased slightly higher than control group and before onion oil administation, while plasma glucose level decreased significantly as compared to before onion oil administration and the same sampling time of control group (P<0,05). In the study, before and after hypercholesterolemia and after onion oil administration, it was not determined striking changes in respect of erythrocytes, leucocytes counts, haemoglobine amount and haematocrit values in both groups and between groups.Öğe Deneysel Hiperkolesterolemi Oluşturulan Köpeklerde Bazı Hematoloji?k Parametreler Üzeri?ne Soğan Yağının Etki?si?(Selçuk Üniversitesi, 1995 Nisan) Keskin, Ercan; Durgun, Zafer; Kocabatmaz, Mehmet; Eryavuz, AbdullahEight dogs, 8-10 months aged, were used in the investigation.

Forty male Ramlic lambs, 2.70 +/- 0.30 months of age, and weighing approximately 16.44 +/- 0.41 kg, were used. Lambs were divided into 4 groups as follows: faunate + control diet (FC), defaunate + control diet (DC), faunate + experimental diet (FE), and defaunate + experimental diet (DE). The control diet contained plant protein as a N source, whereas the experimental diet was supplemented with urea and sulfur, both at 3% of BW per day. The forage portion of the diet was 350 g of alfalfa hay per lamb per day. Diets were fed twice daily in equal amounts. Defaunation, or feeding a diet supplemented with urea and sulfur in place of plant protein sources, had no effect on ruminal fluid Na concentrations but there was an interaction on Na concentration in the rumen fluid. Ruminal K concentration was lower (P < 0.021) in the experimental diet versus the control diet, while it was not affected by defaunation. There was an interaction effect on Zn concentration in rumen fluid. Plasma Na, K and Zn concentrations were not affected by treatments, whereas defaunation significantly decreased (P < 0.048) plasma Fe concentration. Defaunation or N source had no effect on Na, K, Zn and Fe concentrations in wool. We concluded that both defaunation and feeding a diet supplemented with urea and sulfur in place of plant protein sources did not affect blood plasma, except for Fe, and wool Na, K, Zn and Fe concentrations despite differences in their ruminal concentration.Öğe Effects of Supplementation of Different Source and Level of Oil to Diet on Lipid Peroxidation and Some Blood Parameters in the Layer Hens(MEDWELL ONLINE, 2008) Cetingul, I. Sadi; Eryavuz, Abdullah; Aslan, Recep; Dundar, Yylmaz; Inal, FatmaThis research has been performed to determine the effects of Hazelnut Oil (HO) and Sunflower Oil (SO) added in the layer ration at various levels as an energy source onto lipid peroxidation and blood parameters of laying hens. Eight hundred laying hens at 135 days of age were used as research material in this experiment. The hens were divided into 5 groups and then each group was divided into 10 subgroups containing 16 hens each. No oil was added in feeds of control group. The other groups were given 15 g kg(-1) HO; 15 g kg(-1) SO; 30 g kg(-1) HO and the last one was mixed oil given 30 g kg(-1) MO (15 g kg(-1) HO + 15 g kg(-1) SO). No difference has been observed in terms of Malondialdehyde (MDA), Glutation (GSH), Total Cholesterol (TCH), mean corpuscular volume (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), Mean Cell Volume (MCV), glucose, White Blood Cells (WBC), Red Blood Cells (RBC), Hemoglobin (HB Packed Cell Volume (PCV) and Thrombocyte (TB) values among the groups. The source and level of the oil used in this study did not affect lipid peroxidation and hematological values.Öğe Faunalı ve Faunasız Ankara Keçilerinde Rasyona Çinko Katılmasının Bazı Rumen ve Kan Metabolitleri ile Tiftik Verimi ve Niteliğine Etkileri(Scientific Technical Research Council Turkey, 2002) Eryavuz, Abdullah; Durgun, Zafer; Keskin, ErcanThis study was conducted to determine the effects of defaunation and zinc on weight gain mohair production and quality as well as on some parameters related to blood and rumen contents in Angora goats In the study 24 male Angora goats aged 10 12 months and weighing approximately 18 kg were used The animals were equally divided into four groups as faunated (F) defaunated (D) faunated +Zn (F+Zn) and defaunated +Zn (D+Zn) Groups F and D were fed with a control ration containing 35 ppm Zn the groups F+Zn and D+Zn were fed with the same ration supplemented by 250 ppm Zn ad libitum during the investigation Defaunation and adding zinc to the ration did not affect the pH level of the rumen content NH3 N levels of the rumen contents in group F were found to be significantly higher (p<0 05) than those in groups D and D+Zn but not significantly higher than those in group F+Zn except for the first month In the investigation zinc levels of the rumen fluid and plasma determined in groups F+Zn and D+Zn were found to be higher (p<0 05) than those in groups F and D Plasma urea nitrogen levels recorded in the defaunated groups were higher than those in the faunated groups at the same sampling times and those differences at the last three sampling times were significant (p<0 05) During the study zinc supplementation of the ration on protozoon counts of the rumen contents in groups F and F+Zn did not cause any difference Entodinium ssp made up 97 8 88 3% of total protozoa The mean zinc levels of the mohair in group D+Zn were found to be higher (p<0 05) than those in group D Also the same parameter in group F+Zn was determined to be higher (p<0 05) than that of group F The mohair production in the defaunated groups was detected to be higher (p<0 05) than that in the faunated groups The mohair yield in the defaunated groups was recorded higher than that in the faunated groups In the study the longest mohair fibre lengths were obtained in groups D D+Zn F and F+Zn (in order of increasing length) In the defaunated goats the mean diameter levels of the mohair samples taken from regions of the shoulder side and britch were found to be higher than those in the faunated goats There were no effects of the defaunation and zinc supplementation to the ration on the weight gain As a result defaunation can be used to increase mohair production of Angora goats when the ration has a low zinc level.Öğe Koyunlarda Rumene Verilen Glikozun Rumen pH'si, Uçucu Yağ Asitleri ve Protozoonlar Üzerindeki Etkisi(Selçuk Üniversitesi, 1996) Keçeci, Tufan; Kocabatmaz, Mehmet; Eryavuz, AbdullahThe present study was carried out to investigate the effect of glucose that infused into rumen on ruminal pH, volatile fatty acids (VFA) and protozoa in two sheep that had been fitted with ruminal fistula. The study was conducted two period and each period contunied during 12 days. Feed was given to the animals once a day. After each feeding, sheep were ruminally infused with 500 ml (4. 2 ml/min) either deionized water (Period I) or 40% glucose so- lution (Period II). Samples of rumen contents were collected from each sheep before feeding, and 2h. 4h and 6h after infusion through the ruminal fistula. In the period i, ruminal pH and protozoa counts of sheep were found to be highest levels before feeding, compared with the levels of same parameters after feeding hours. Whereas, total VFA levels of sheep were determined to be lower amounts before feeding. Compared with the levels of same parameters in the Pe. nod I, the ruminal pH values, acetic acid levels, protozoa counts and proportions of Entodinium minimum were found to be lower amounts, but propionic acid level and proportions of Isotricha species were higher in the sheep alter glucose infusion in the Period II.
