Determination Of Performances Some Important Races And Ecotypes Of Turkish Honeybees (Apis Mellifera L.) Under Migratory Beekeeping Conditions, Ahmet Güler, Osman Kaftanoğlu Jan 1999

Determination Of Performances Some Important Races And Ecotypes Of Turkish Honeybees (Apis Mellifera L.) Under Migratory Beekeeping Conditions, Ahmet Güler, Osman Kaftanoğlu

Turkish Journal of Veterinary & Animal Sciences

This study was conducted to compare performances of some important honeybee (A. mellifera L.) races and ecotypes in Turkey. Experimental colonies were collected from 6 different regions such as Central Anatolia Region (Beypazary), North Eastern Anatolia Region (Posof), Marmara Region (Gökçeada); Thrace Region (Saray), Aegean Region (Fethiye) and Mediterranean Region (Erdemli). Genotypes were compared with respect to some physiological characteristics including honey yield, wax building activity, development of colony population and brood rearing activity. During 2 years of experiment the Muğla genotype was superior to the other genotypes in terms of development of colony population, brood rearing activity, wax building …

Sensory Properties And Firmness Of Some Fermented Dairy Products Made From Cow And Ewe's Milk, Ni̇hat Akin Jan 1999

Sensory Properties And Firmness Of Some Fermented Dairy Products Made From Cow And Ewe's Milk, Ni̇hat Akin

Turkish Journal of Veterinary & Animal Sciences

Concentrated fermented bifidus milk, acidophilus milk, Bifidus yogurt, Bioyogurt and yogurt were made from cow's and ewe's milk by using ultrafiltration and traditional methods. Sensory analysis and firmness was determined from concentrated fermented milk samples. The firmness of concentrated fermented milk products produced from cow's and ewe's milk by using ultrafiltration and traditional methods were significantly different (p < 0.05). However, the type of starter culture used and the interaction between product types and production methods was not significantly different (p > 0.05). Further, the different type of milk used and products were significantly affected on sensory properties of samples. All the products from cow's milk were marked with high scores. In addition, the most of panelist preferred yogurt to the other fermented dairy …

Investigation On Serum Ca And P Levels In Cows With Retained Placenta, Hali̇s Öcal, Yusuf Türköz, Hayretti̇n Çeti̇n, Erdal Kaygusuzoğlu, Ali̇ Ri̇şvanli, Cahi̇t Kalkan

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to investigate serum Ca and P levels in 31 cows with retained placenta (RP) and 8 cows without RP (control group). The RP was observed following normal parturition in 21 cows (RPP), and the remaining 10 cows had RP after abortion (RPA). Serum Ca and P levels did not differ significantly between the cows with RP and the control group (p>0.05). When the cows with RP were subdivided into two groups as the cows with RPP and those with RPA; the difference in the levels of P between these groups and the control group …

Some Properties Of Purified And Non-Purified Rumen Tissue Arginase In Cattle, Mi̇ne Eri̇şi̇r, Sema Temi̇zer Ozan Jan 1999

Some Properties Of Purified And Non-Purified Rumen Tissue Arginase In Cattle, Mi̇ne Eri̇şi̇r, Sema Temi̇zer Ozan

Turkish Journal of Veterinary & Animal Sciences

Some biochemical properties of purified and non-purified rumen tissue arginase were compared. Homogenization, heating, treatment with aceton, precipitation with ammonium sulfate, dialysis, several centrifugations, gel filtration on sephadex G-200 processes were utilized in the purification procedure of the enzyme. It was found that pre-incubation temperature (60 °C) of arginase and Km (4mM) to its substrate, L-arginine, did not change before and after purification. While pre-incubation period was 10 min and optimal pH 9.7 before purification, pre-incubation period was found to be 5 min and optimal pH 10 after purification. Purified enzyme achieved its highest activity at 2 mM MnCl_2 concentration, …

Pathomorphologic And Biochemical Studies On Experimental Sodium Toxication In Broilers, Hati̇ce Eröksüz Jan 1999

Pathomorphologic And Biochemical Studies On Experimental Sodium Toxication In Broilers, Hati̇ce Eröksüz

Turkish Journal of Veterinary & Animal Sciences

Pathomorphological and biochemical findings related to experimental sodium toxication were studied. Sixty male chicks were divided into five different groups. Sodium bicarbonate (group-1 and 2) and sodium chloride (group-3 and 4) were added into tap water at 6 and 12 g/l doses, respectively. The chicks in all groups were fed on standart chick and standart broiler ration. Cardiac enlargement and various degree of visceral uricosis were the main macroscopic lesions detected in group-1 and group-2. In group-3 and 4, such macroscopic lesions cardiac enlargement, testicular edema, hemorrhagic gastritis as were detected. Microscopic examinations showed the lesions related to macroscopic ones. …

Effect Of Different Enzyme Supplementation On The Performance And Ileal Ph Of Broilers Fed Wheat-And Barley-Based Diets, Müjdat Alp, Recep Kahraman, Neşe Kocabağli, İsmai̇l Abaş, Harun Aksu Jan 1999

Effect Of Different Enzyme Supplementation On The Performance And Ileal Ph Of Broilers Fed Wheat-And Barley-Based Diets, Müjdat Alp, Recep Kahraman, Neşe Kocabağli, İsmai̇l Abaş, Harun Aksu

Turkish Journal of Veterinary & Animal Sciences

This experiment was conducted to study the effects of different enzyme supplementation to wheat-and barley-based diets on the live weight gain, feed efficiency, dressing percentage and ileal pH of broiler chickens. Two hundred fourtyfive, day-old Ross-PM3 chicks were randomly assigned to a control and four treatment groups. Starter (1 to 21 days old) and grower (22 to 42 days old) diets were given without (control) or with different enzyme preparations, which are Avizyme 1200 (1000 mg/kg), Kemzyme Dry (500 mg/kg), Roxazyme-G (200 mg/kg) and Wheatzyme (700 mg/kg). At the end of the six week, average live weights of broilers were …

Determination Of Pregnancy, Embryonic-Fetal Mortality, Ovarium Functions And Uterus Diameter In Cows By Ultrasonography, Seli̇m Aslan, German Wesenauer Jan 1999

Determination Of Pregnancy, Embryonic-Fetal Mortality, Ovarium Functions And Uterus Diameter In Cows By Ultrasonography, Seli̇m Aslan, German Wesenauer

Turkish Journal of Veterinary & Animal Sciences

In this study 57 cows at the puerperal stage (between 15-45 days) and at early pregnancy period (between 8-58 days) were subjected to clinical and Ultrasonography check at 10-day intervals. On the 8 th day of post insemination (p.ins.) areas of nidation ranging from 0,5-1,5 cm were established by means of US (n=53) and on 40 animals (70,2%) the development of these areas were followed until the 58th day of pregnancy. In the other 13 cows (22,8%), begining from early embriyonic featal deaths (18) days and late embriyonic featal deaths (28 days) were established ultrasonographycally. 4 animals (7,0%) that no …

Turkish Journal of Veterinary & Animal Sciences

Serum samples collected from randomly-selected 395 cattle between June-November 1997 from the districts and central villages of Elazığ were used to determine the seroprevalence of Leptospirosis in cattle. Microscopic Agglutination Test (MAT) was used to examine serum samples for antibodies to L. hardjo, L. grippotyphosa, L. pomona and L. icterohaemorrhagiae. Positive results were obtained from eight (2.03%) samples; seven (1.77%) of which were agglutinated with L. hardjo and one (0.25%) with L. grippotyphosa antigens. There was a statistically significant difference when the seropositivity rates were compared in different districts (p=0.002). Age and sex were not determined to affect the frequency …

Turkish Journal of Veterinary & Animal Sciences

In this study, the effects of water current on nutrient components of trout (Oncorhynchus mykiss) were investigated. One year old fish averaging 550±0.06 g were used in the experiment which lasted for 3 months. In the experiment, the fish were reared in two tank of 1800 l each in the first tank (group A), water current was 1.5-2 fish length (25 cm)/sn while in the second tank (group B) there was no water current. In group A while the fillets contained 68.89±1.47 % dry matter, 19.71±0.66 % protein, 9.91±1.81 % lipit, the fillet of group B had 69.32±1.15 % dry …
