The Effect Of Dietary Vitamin E On The Arginase Activity In The Females Of Freshwater Crayfish (Astacus Leptodactylus, Esch. 1823), Mi̇ne Eri̇şi̇r, Özden Barim, Mehtap Özçeli̇k, Muzaffer Mustafa Harlioğlu

Turkish Journal of Veterinary & Animal Sciences

The effects of different levels of dietary vitamin E on the arginase activity of the hepatopancreas, gills and muscle of freshwater crayfish (Astacus leptodactylus) were investigated. The control diet contained approximately 37.41% crude protein on a dry-weight basis and 3.25 kcal g^{-1} gross energy. The diet ingredients contributed 65.83 mg kg^{-1} vitamin E to the control diet. Levels of 34.17 mg kg^{-1}, 84.17 mg kg^{-1} and 134.17 mg kg^{-1} vitamin E (DL-a-tocopherol acetate) were added to the control diet to supply 100 mg kg^{-1} in diet 1, 150 mg kg^{-1} in diet 2 and 200 mg kg^{-1} in diet 3, …

Plasma Ascorbic Acid Levels In Lambs With Coccidiosis, Şi̇ma Şahi̇nduran, Kenan Sezer, Tülay Büyükoğlu, Bayram Ali̇ Yukari, Meti̇n Koray Albay

Turkish Journal of Veterinary & Animal Sciences

This study evaluated 30 lambs, 20 naturally infected with coccidia oocysts (infected group) and 10 healthy lambs (control group). Blood samples were collected from both groups for evaluation of ascorbic acid values in plasma and blood cells analysis. Mean plasma ascorbic acid values in the infected group were lower than those in the control group (0.76 ± 0.19 and 2.00 ± 0.58 mg/dl, respectively). A decrease in erythrocyte, haemoglobin and haematocrit values and an increase in leukocyte values were determined.

Comparison Of Polymerase Chain Reaction And Conventional Methods For The Diagnosis Of Listeria Monocytogenes In Stuffed Mussels, Ergün Ö. Göksoy, Şükrü Kirkan, Osman Kaya Jan 2006

Comparison Of Polymerase Chain Reaction And Conventional Methods For The Diagnosis Of Listeria Monocytogenes In Stuffed Mussels, Ergün Ö. Göksoy, Şükrü Kirkan, Osman Kaya

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to evaluate the role of stuffed mussel as a source of Listeria monocytogenes. Polymerase chain reaction is a rapid procedure with both sensitivity and specificity for quick detection and identification of L. monocytogenes. A total of 50 mussel samples were investigated for L. monocytogenes. L. monocytogenes was not identified by the conventional method. However, PCR amplification products demonstrated that 5 out of 50 samples showed positive reactions with L. monocytogenes. The PCR positive samples showed specific amplification at approximately 343 bp for L. monocytogenes.

The objective of this study was to compare the performances of calves fed acidified milk replacer (AMR) or sweet (regular) milk replacer (SMR) at 8% of birth weight. Twenty-one calves (10 males, 11 females) were offered replacers reconstituted to 12% of dry matter over 5 weeks. In the group fed AMR, daily body weight gains of calves at the different stages of growth were comparable to those for calves fed SMR. In the preweaning period, calves offered AMR had similar dry matter intakes from starter, milk replacer and dry hay as well as total intake as those fed SMR. In …

Qingsheng Li Publications

Here we report the results of an investigation into the possibility that one mechanism responsible for the establishment of persistent human immunodeficiency virus infection is an early regulatory T (Treg) cell response that blunts virus- specific responses. Using the simian immunodeficiency virus (SIV)–infected rhesus macaque model, we show that, indeed, viral replication and immune activation in lymphatic tissue drive a premature immunosuppressive response, with dramatic increases in the frequencies of CD4+CD25+FOXP3+ Treg cells, transforming growth factor–β1+ cells, interleukin–10+ cells, and indoleamine 2,3-dioxygenase+CD3+ cells.When we compared SIV infection with rhesus cytomegalovirus (RhCMV) …

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li Jan 2006

Power Analysis For A Mixed Effects Logistic Regression Model, Yinmei Li

LSU Doctoral Dissertations

In herd health studies, the mixed effects logistic regression model with random herd effects are commonly used for modeling clustered binary data. These models are well developed and widely used in the literature, among which is the logistic-normal regression model. In contrast to the rich literature in modeling methods, the sample size/power analysis methods for such mixed effects models are sparse. The sample size/power analysis method for the logistic-normal regression model is not readily available. This study is to develop a power analysis/sample size estimation method for the logistic-normal regression model. Extended from the sample size method for the likelihood …

Meat Prices And Factors Affecting Them In Turkey, Yavuz Cevger, Engi̇n Sakarya Jan 2006

Meat Prices And Factors Affecting Them In Turkey, Yavuz Cevger, Engi̇n Sakarya

Turkish Journal of Veterinary & Animal Sciences

Secondary data from different sources were used to examine the changes in red meat prices in Turkey between 1976 and 1989 taking account of the impacts of inflation and red meat imports during that period. It is observed that in current prices a higher price increase was realized in red meat prices compared to the fattening feed prices in the period 1976-1999. When the effects of inflation and purchasing power of money are taken into account, it is determined that red meat prices rose at an increasing rate, whereas feed prices decreased after 1995. On the other hand, it was …

Effects Of Dietary Fluoride Levels On Growth, Serum Indexes And Antioxidant Systems In Growing Pigs, Xin Tao, Zi Rong Xu, Yi Zhen Wang Jan 2006

Effects Of Dietary Fluoride Levels On Growth, Serum Indexes And Antioxidant Systems In Growing Pigs, Xin Tao, Zi Rong Xu, Yi Zhen Wang

Turkish Journal of Veterinary & Animal Sciences

Ninety-six growing pigs were used to evaluate the effects of fluoride levels on growth performance, serum indexes and antioxidant systems. Four dietary treatments were formulated by supplementing fluorine (as NaF) to provide the following added fluorine levels: 0, 50, 100 and 150 mg/kg. The results showed that pigs consuming diets with 100 and 150 mg/kg fluorine added had poor growth performance, and most serum biochemical indexes were significantly altered compared to the control (P < 0.05). On the other hand, serum and liver MDA concentration significantly increased due to the addition of 150 mg/kg fluorine (P < 0.05). T-AOC levels and the activities of SOD, GSH-PX, CAT and GST of serum and liver in fluoride added groups decreased, most of which altered significantly (P < 0.05). These results indicated that excessive fluoride ingestion had an adverse effect on animal health and performance.

Turkish Journal of Veterinary & Animal Sciences

Coxiellosis is a zoonosis caused by Coxiella burnetii. This study conducted to determine the prevalence of coxiellosis in cattle and farmers in Eastern Turkey. A total of 230 cattle and 92 human sera were collected and tested for antibodies against C. burnetii by a commercial ELISA kit. The antibodies to C. burnetii were detected in 22 (9.56%) cattle and 18 (19.5%) healthy farmers. Seropositivity was found in 12 of 53 (22.6%) cattle with an abortion history, and 10 of 177 (5.6%) cattle without an abortion history (P < 0.05). There was a correlation between animal and human seroprevalence in the same district. It was observed that the seroprevalence of coxiellosis was higher in northern districts (32.4% in farmers and 15.4% in cattle) than in other districts (12.1% in farmers and 6.5% in cattle) both for humans and animals (P < 0.05). Coxiellosis was an important health problem in both humans and cattle, and the disease may cause abortion in cattle in Eastern Turkey.
