The aim of the present study was to evaluate the effectiveness of right fossa paralumbar colostomy on the survival rate of calves with atresia coli maintained under Anatolian farming conditions. The clinical diagnosis was confirmed by clinical findings, pain and contrast radiographic examination. In clinical and indirect radiographic examination, rectum and descending colon were seen as more constricted than usual. In surgery, the abdominal cavity was opened through a vertical incision from the right paralumbar fossa. The blind end of the ascending colon was fixed to the abdominal wall in order to create a stoma. The postoperative course of the calves was obtained from the owners of the calves during a period of four months. It was learned that only one calf survived and the others died because of diarrhea within the four month period. In conclusion, this study demonstrated that although right fossa paralumbar colostomy was successfully performed for type-II atresia coli, severe functional impairment and fluid imbalance due to the loss of an important fluid resorption resulted in the death of most calves that were kept under Anatolian farming conditions.

The aim of the study was the analysis of the effect of calving season on the course of parturition and rearing results of Polish Holstein-Friesian calves of Black-and-White strain from birth to 3 months of age. Easy calvings (1;2) predominated on the farm. In spring, they accounted for 91.2% of all calvings occurring in this season. The respective values for summer, winter and autumn were 89.7%, 88.6% and 87.6%. The highest mean birth weight was characteristic of calves born in winter (40.8 kg and 44.2 kg for heifer calves and bull calves, respectively). The highest mean daily body weight gains in the whole rearing period were achieved by heifer calves born in winter (704 g) and bull calves born in spring (750 g). In the group of heifer calves and bull calves, statistically significant differences during the analysed rearing period were found (P≤0.01, P≤0.05). The highest percentage of ill calves was found in the autumn-winter season and the lowest one in spring and summer.

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.

The aim of the study was to investigate the influence of Mycoplasma bovis challenge in calves on the alteration of acute- phase response (APR). The study was performed on twelve calves aged 4-8 weeks. The animals were divided into two equal groups: experimental and control. Calves in the experimental group were intratracheally challenged with pathogenic strain of Mycoplasma bovis, whereas controls received sterile physiological saline as placebo. The blood samples were collected before (1st d) and after the mycoplasma challenge (3, 5, 7 and 9th d). The following parameters were assayed in serum: acute phase proteins (APPs), i.e. haptoglobin (Hp) and amyloid A (SAA), and eicosanoids such as prostaglandin E₂ (PGE₂), prostaglandin F₂ₐ (PGF₂ₐ), leukotrien B4 (LTB₄), and tromboxan B₂ (TXB₂). In calves of experimental group, a significant increase in concentrations of Hp and SAA was observed when compared with the controls. A decrease in both APPs to the initial values, i.e. before the challenge, was noted on the 9th d of experiment. On the other hand, the inoculation of Mycoplasma bovis caused a significant increase of the examined eicosanoids, which maintained elevated during the whole study. The stimulation of synthesis of APPs and eicosanoids in response to the challenge with Mycoplasma bovis probably indicates the effective activation of APR under these conditions.

We observed 75 Aberdeen Angus calves born in the years 2004–2007 and managed on pastures and wild areas of Karsibór, an island located in the northern part of the Szczecin Lagoon. An analysis was carried out on the results of maternal nursing of the calves in relation to subsequent calving, sex of the calf, and year of rearing.Asignificant (P≤0.01, P≤0.05) effect of subsequent calving on body weight of the calves being born was observed. The calves from the first calvings had significantly lower body weight at birth as compared to those born from the subsequent calving. On the other hand, there were no significant effects of the subsequent calving on body weight and daily weight gain of calves after weaning, even though the calves from the first calving were characterized by poorer performance in this respect. Significant differences between the data on calf nursing performance recorded in each individual year of the study result from the fact that the animals grazed on poorer quality pastures and unused land.

The main aim of the study was to compare rearing effect of calves kept outdoor in individual hutches and indoor in group pens. During the experiments following measurements were taken: body weight, daily and monthly gains and mortality. Study was conducted on 90 calves from 5th to 90th days of age and measures were taken in 3 seasons - spring, summer - autumn and winter. All calves were fed with the same feed and according to the same schedule. Results reviled that during first month calves from both groups achieved the same daily gains. However, older calves kept indoor characterized themselves by better gains and body weight. During the experiment only 2 claves were lost (mortality rate - 2.2%).

The aim of the study was to investigate acid-base changes and to determine some serum biochemical parameters in dehydrated calves with diarrhoea according to the degree of dehydratation. Thirty diarrhoeic dehydrated calves submitted to treatment in the university clinic, were used in the study. The calves were accessed as suitable for this study, if they were moderately or severely dehydrated according to clinical symptoms. All sick calves had the usual yellow and watery diarrhoea. Calves with 4% to 8% dehydration (moderate) had a weak suckle reflex, dry mucous membranes, warm mouth and partly good muscular tone. Calves with 10% and above dehydration (severe) were unable to stand, and had no suckling reflex and cold mouth. The mean pH, base excess, chloride (only severely dehydrated group) and sodium were -significantly decreased in both moderately and severely dehydrated groups. On the other hand, potassium, phosphorus, HCO₃⁻ and anion gap levels were increased, compared to that of the control group. Results of this study showed that there was a relationship between the base excess and anion gap, with a degree of clinical dehydration. However, there may not be an exact correlation between the degree of dehydration and the severity of acidosis. Based on the clinical symptoms, the results of this study could be a useful tool under field conditions, in estimating the base excess in diarrhoeic dehydrated calves, when acidosis therapy is needed.

Evaluation of the immunogenicity of the vaccine against respiratory tract infections in calves caused by Pasteurella multocida, and prepared from antigen of a local strain of serotype 3 with oil adjuvant addition, was the object of the prescnt studies. Two experiments were carried out using calves. Vaccine was given them at a dose of 2 ml i.m., twice every 14 days. In experiment 1, sera were obtained before vaccination, 2 and 5 weeks after the first vaccination, in experiment 2 - before vaccination, 2 weeks, 1 and 2 months after the first vaccination. lmmunogenicity of the vaccine was evaluated by means of an agar gel immunodiffusion (AGID) test and an ELISA test. The carrier-state of Pasteurella multocida on mucous membrane of nasal cavity was examined. lt was found that immunisation stimulated the production of the specific precipitins for serotype 3 and it caused the increase of IgG level found using ELISA test with microplate coated with whole-bacterium antigen or LPS of that serotype. The investigation confirms the good immunogenicity of the vaccine.
