Opis:
Information regarding the correct pedigree of and relationship between animals is useful for managing dairy breeding, reducing inbreeding, estimating breeding value, and establishing correct breeding programs. Additionally, the successful implementation of progeny testing is crucial for improving the genetics of dairy cattle, which depends on the availability of correct pedigree information. Incorrect pedigree information leads to bias in bull evaluation. In this study, Neogen GeneSeek Genomic Profiler (GGP) 50K SNP chips were used to identify and verify the sire of Taiwanese Holstein dairy cattle and analyze the reasons that lead to incorrect sire records. Samples were collected from 2,059 cows of 36 dairy farms, and the pedigree information was provided by breeders. The results of sire verification can be divided into three categories: submitted unconfirmed sire, submitted confirmed sire, and incorrectly submitted verified sire. Data on the sires of 1,323 (64.25%) and 572 (27.78%) dairy cows were verified and discovered, respectively. Sires of 1,895 (92.03%) dairy cattle were identified, which showed that the paternal pedigree of dairy cattle could be discovered and verified through genetic testing. An error-like analysis revealed that the data of 37 sires were incorrectly recorded because the bull’s NAAB code number was incorrectly entered into the insemination records: for 19 sires, the wrong bull was recorded because the frozen semen of a bull placed in the wrong storage tank was used, 6 had no sire records, and for 12 sires, the NAAB code of the correct bull was recorded but with a wrong stud code, marketing code, or unique number for the stud or breed. To reduce recorded sire error rates by at least 27.78%, automated identification of the mated bull must be adopted to reduce human error and improve dairy breeding management on dairy farms.

Opis:
The effects of feeding, fasting, and re-feeding on the ruminal profile of growing cattle were studied. Ruminal fluid and urine samples were obtained from 12 crossbred steers weighing approximately 300 kg during the following periods: 11 h of normal feeding (postprandial period), 48 consecutive hours of fasting, and followed by 48 h of re-feeding. Fasting promotes changes in the ruminal profile, such as an increase in ruminal pH, reduction in the number of rumen protozoa and bacteria, and decrease in the urinary excretion of allantoin; however, it does not change the urinary uric acid excretion rate. The overall mean ruminal pH was higher during fasting (7.53±0.27) in comparison to those at normal feeding (6.72±0.25) and re-feeding (6.62±0.31) (p<0.05). During re-feeding, the ruminal profile returned to normal, except for the protozoa count, which despite a slight increase only after 48 h of re-feeding, did not recover to baseline values.

Opis:
Ruminal acidosis is frequent in cattle fattening systems associated with grain-rich fibre-poor diets. This study aimed to assess the prevalence of ruminal lesions compatible with ruminal acidosis intensive fattening farms and its risk factors on farm. Rumens of 218 out of 1960 bullocks from six farms were classified in slaughterhouses, and the management practices and the type of feed were compared. The prevalence of lesions compatible with ruminal acidosis was high (65%), where 47% and 18% of the animals had ruminal lesions compatible with subacute and acute disease, respectively. Prevalence of lesions differed significantly between the farms, with differences in the management and feeding practices. Ruminal lesions compatible with ruminal acidosis are prevalent in cattle fattening units in Portugal and husbandry and feeding practices are likely to have an impact.

Opis:
In the present study we investigated the effect of bovine conglutinin on the phagocytic activity of leukocytes. We measured both the chemotactic activity of conglutinin and its effect on the internalization of zymosan particles and E. coli by granulocytes. We also assessed the binding of conglutinin to various microorganisms isolated from clinical cases in cattle. We showed that conglutinin binds strongly to the surface of yeast cells and to mannan-rich zymosan particles, while weak binding was observed in the case of the bacterial strains tested, including those whose O antigen is composed of mannan. Conglutinin (1-10 μg/ml) neither acts as a chemotactic factor for peripheral blood leukocytes nor affects ingestion of E. coli by granulocytes. However, as flow cytometry based assay showed, conglutinin (0.1-1 μg/ml) increased ingestion of zymosan expressed as mean fluorescence intensity (MFI) of positive cells.

Opis:
Theileriosis is a hemoparasitic disease that affects a wide range of different animal species and is caused by various species of Theileria. This study aimed to determine the molecular epidemiology of Theileria annulata through microscopy and PCR, in crossbred cattle in some districts of Khyber Pakhtunkhwa, Pakistan. For this study, a total of 384 blood samples were collected from cattle in the Peshawar (n=120), Charsadda (n=94), Nowshera (n=84), and Swabi (n=86) districts. Microscopy and PCR were used to determine the overall prevalence of theileriosis, which was found to be 15.8 and 22.6%, respectively. Theileria annulata was detected in blood samples through PCR in the study area, and the target gene i.e., Tams 1, of positive samples was sequenced. The sequences in the current study revealed high sequence homology (ranging from 96 to 100%) with Tams 1 sequences of neighboring countries present in the NCBI database. Season, breed, age, and sex were found to be important risk factors among the several risk factors examined, whereas, among different clinical manifestations, lymphadenopathy showed a strong association with theileriosis. According to Cohen’s kappa and ROC analysis, microscopy was proven to be a fair diagnostic test for detecting theileriosis in cattle, and may be used in combination with molecular techniques for screening a large number of animals.

Opis:
Antimicrobial resistance in Salmonella has been associated with the presence of integrons and many other resistance mechanisms contributing to the spread of antimicrobial-resistant genes within and between livestock and human populations. In this study, the presence of Salmonella serovars from broiler and cattle samples and their antimicrobial resistance, integrons, tet resistance, ESBL and resistance genes carriage were investigated. Total of 209 litter (broiler farms) and fecal samples (cattle farms) were examined by bacteriological procedures, susceptibilities against 18 antimicrobials and genes carriages were detected by singleplex and multiplex PCR. A total of 46/209 (22 %) Salmonella strains were isolated. Six different Salmonella serotypes from 46 Salmonella isolates were identified and the most common serotype was S. Infantis 38 (82.6%) from broiler litter; followed by S. Kitenge 3 (6.5 %) from fecal sample. The highest occurrence of resistance observed for penicilline (46/46, %100), lincomycin (43/46, 93.5%) and 42 isolates (43/46, 93.5%) exhibited MDR. The overall occurrence of class 1, 2 and 3 integrons carrying Salmonella in tested samples were 63.04% (29/46), 43.5% (20/46) and 84.8% (39/46) respectively. Out of the 27 isolates produced an ESBL, mostly CTX and TEM. On 46 Salmonella isolates, in 16 (34.8%) Tcr’ genes were determined. Genotypic and phenotipic detection of ESBL genes found within integrons from Salmonella isolates from different sources (broiler and cattle) can provide powerful information about health and economic risk associated with transferable multidrug resistance.

Opis:
Campylobacter species are among the most frequently identified bacterial causes of human gastroenteritis. Because Campylobacter spp. harbored by cattle can be transmitted to humans, in this study we investigated antimicrobial resistance of thermophilic Campylobacter isolated from cows. Our study included 150 strains of Campylobacter (143 strains of C. jejuni and 7 strains of C. coli) isolated from cows in South-Western Poland. The minimal inhibitory concentration (MIC) to ciprofloxacin, erythromycin, gentamicin and tetracycline were determined using the agar dilution methodology. All strains of C. coli were susceptible to all four drugs studied. The most frequently detected resistance of C. jejuni was to ciprofloxacin (26 strains 18.2%). Resistance to tetracycline was observed in 5 strains (3.5%). All strains of C. jejuni were susceptible to erythromycin and gentamicin.

Opis:
The aim of the present study was to determine whether ultrasonographic evaluation of the hepatic parenchyma could be used as a diagnostic and prognostic approach in cows and buffaloes with hepatic lipidosis. For this purpose, cows (n=16) and buffaloes (n=10) with fatty infiltration of the liver were examined by ultrasonography. Treated cows and buffaloes were monitored for hepatic changes ultrasonographically, biochemically and histologically. Clinical findings were non-specific and included anorexia, recumbency, muzzle necrosis, and icteric mucosal membranes. Laboratory data revealed neutrophilia, hyper γ-globulinemia, elevated activities of aspartate aminotransferase, γ-glutamyl transpeptidase, creatine kinase and lactate dehydrogenase, and high concentrations of insulin, total bilirubin, non-esterified fatty acids and β-hydroxyl butyric acid. Laboratory results 7, and 21 days after treatment showed progressive improvement in the chemistry profile. On admission, ultrasonographic examination of the hepatic parenchyma in cows and buffaloes revealed either increased or decreased hepatic echogenicity; histologic examination revealed marked fatty infiltration of the hepatocytes. One week after treatment, the hepatic parenchyma was visualized easily, liver boundaries were clearly imaged, and histologic examination of hepatic specimen showed a moderate degree of fatty infiltration. Three weeks after treatment, the hepatic parenchyma was almost similar to normal, the hepatic and portal blood vessels could be easily imaged, and the histologic picture had greatly improved where the liver resembled the normal organ. Six cows and seven buffaloes made a full recovery while the remaining ten cows and three buffaloes were slaughtered and thoroughly examined postmortem. Ultrasonography showed a good correlation with histologic and laboratory findings.
