This study was carried out to determine the levels of various cytokines (TNF-α, IL-6, IL-8) and acute phase proteins (haptoglobin, C-reactive protein, serum amyloid A, alpha 1-acid glycoprotein, lactoferrin, and fibrinogen) in pneumonic calves, to reveal changes in these parameters depending on etiologic factors (bacterial, viral, bacterial + viral) in calf pneumonia, and to determine whether these parameters could be used for diagnosis and prognosis of the disease. The study was carried out on a total of 50 calves consisting of 10 healthy and 40 pneumonic animals aged 1 to 6 months. The pneumonic calves were classified into three groups: bacterial, viral and mixed (bacterial + viral). It was found that the levels of IL-6, IL-8, CRP, and TNF-α were statistically higher in the pneumonic calves than in the control group animals. It was found that the increase in levels of Serum IL-6, IL-8, and CRP were highest in the mixed infection group (bacterial + viral) and lowest in the virally infected group. Similarly, serum levels of Hp, CRP, SAA, α-1-AGP, and LF were found to be more statistically significant (P <0.01) in the infected calves than in the control group animals, but changes in fibrinogen levels were not statistically significant. Although the TP and ALB levels in the pneumonic calves were numerically higher than the same parameters in the control group, this was not statistically significant (P > 0.05). As a result, this study showed that serum levels of cytokines (IL-6, IL-8, TNF-α) and serum concentrations of acute-phase proteins (Hp, CRP, SAA, α-1-AGP, and LF) are significantly higher in the pneumonic calves than in the control group calves. Furthermore, the assessment of cytokine and acute phase protein levels can play an important role in the early diagnosis of calf pneumonia. This early diagnosis can help prevent deaths caused by pneumonia, which is the leading cause of major losses, and can also be helpful in the early treatment of pneumonia in the veterinary clinical field.

This study was conducted to investigate the prevalence of parasitic protozoan agents in lambs with diarrhoea in the Van province (Eastern Turkey). Faecal samples from 132 diarrhoeic lambs aged from one day to two months old were collected at 12 different herds from January 2005 to May 2005. The faecal samples were examined by using, native-Lugol, Fulleborn's salty water technique, and a Modified Ziehl-Neelsen staining technique for Cryptosporidium. The parasitological examination revealed that 98 (74.24%) of the lambs were infected with one or more of parasitic protozoan agents. Eimeria, Giardia, and Cryptosporidium were detected in 80 (60.60%), 64 (48.48%), and 18 (13.63%) of the lambs, respectively. According to statistical analysis, Eimeria sp. oocysts were significantly higher (P<0.01) in lambs aged between 31 and 60 d (76.81%, 53 of 69) than in those of 16-30 d of age (50%, 21 of 42) and 1-15 d of age (28.57%, 6 of 21). There were significant differences in Giardia prevalance when lambs of 1-15 d of age were compared with those 16-30 d of age (P<0.05). Statistical analysis revealed that Cryptosporidium sp. oocysts were significantly higher (P<0.01) in lambs aged between 1 and 15 d (66.66%, 14 of 21) than in those of 16-30 d of age (4.76%, 2 of 42) and 31-60 d of age (2.89%, 2 of 69). Moreover, Giardia sp. and Eimeria sp. showed significant co-occurrence (34.84%). The results obtained confirmed the fact that protozoan infections are widespread in diarrhoeic lambs in this geographical region.

Serum levels of T₃, T₄, and TSH hormones, some elements, and glucose with regard to their involvement for growth retardation in yearling rams were investigated. A total of 70 yearling rams of the Akkararnan breed, 50 of which were classified with a retarded growth, and the remaining 20 were classified as normal, were included in the study. Serum total T₃, total T₄, and TSH were measured using chemiluminescent enzyme-labelled immunometric assay with immulite kits. Serum levels of Zn, Cu, and Co were measured using atomic absorption spectrophotometer. Serum glucose was measured using auto analyser. There were significant differences between the yearling rams, with and without retarded growth for serum levels of T₃, Zn, Cu, Co, and glucose. However, there no significant differences for T₄ and TSH between the yearling rams, with and without retarded growth. The results of the study suggest that retarded growth in yearling rams is associated with the lower levels of serum total T₃, Zn, Cu, Co, and glucose; however, there is no scientific evidence for the association of T₄, and TSH in the condition.

This study was conducted to evaluate the effects of combined deficiencies of Se and vitamin E on catalase activity in order to investigate the possible interactions between Se, α- tocopherol, and catalase in lambs with white muscle disease (WMD). Ten healthy and fifteen WMD affected lambs of the Akkaraman breed were used. Serum α-tocopherol and Se levels, and catalase activity were analysed. The catalase activity as well as α-tocopherol and Se levels in lambs with WMD before the treatment (day 0), were found to be lower than those of the control group (P<0.001). Therefore, the catalase activity should be taken into consideration in lambs with WMD.
