The objective of the study was to establish routine parentage testing system in Beagle dogs using 22 ISAG (International Society for Animal Genetics) canine microsatellite markers (2005). Blood collections were obtained from a mother dog, 4 candidate father dogs and 3 offspring (n = 8). Genomic DNA samples were extracted from 8 Beagle dogs blood for PCR analysis. PCR products for the allele were analyzed by ABI 3130 DNA Sequencer and GeneScan (Ver 3.0) analysis and Genotyper (Ver. 2.1) software.

This study was performed to investigate the effects of urinary acupoint (BL-23, BL-28) by acupuncture (AP) and electroacupuncture (EA) on urinary bladder in dogs. Four healthy male dogs aged within the range of 6~8 months were used in this experiment. For Electrodes implantation on the bladder, dogs were to undergo surgical operation. The purpose of investigating the effect on urinary bladder was to evaluate electromyogram (EMG) changes according to AP or EA at Shen Shu (BL-23), Pang Guang Shu (BL-28) and non-acupoint.

A 4-year-old spayed female, Yorkshire terrier dog with a history of petechial and ecchymotic hemorrhages on the face, trunk and hind limb was referred to Veterinary Medical Teaching Hospital, Cheju National University. The complete blood count revealed a marked thrombocytopenia (96×10³/㎕). The biochemical profile showed only slightly increased glucose. The coagulation profile such as prothrombin time and activated partial thromboplastin time, was within the reference range. In Giemsa staining, there were no endoparasites like as Babesia spp. on the RBC.

To determine the effects of anesthesia to clove oil on the secondary stress indices, changes in haematological and blood chemistry were monitored in healthy crucian carps (Carassius auratus). 24 fishes were divided into three groups, and blood was collected before anaesthesia (control group), immediately after anaesthesia at a concentration of 30 mg/l clove oil (anesthetized group), and 24 h after anaesthesia (recovered group). The anesthesia to clove oil significantly increased glucose in anaesthetized group, and constantly decreased lactate dehydrogenase in anaesthetized group and recovered group.

Objective—To determine whether selection for the homozygous A136R171 genotype that confers resistance to classic scrapie infection negatively affects production traits in sheep. Animals—996 commercial lambs obtained from 2 flocks at separate locations across 3 consecutive years. Procedures—Genotyping at codon 136 and 171 was performed by use of commercially available testing or a single-nucleotide polymorphism assay. Carcass data were collected without knowledge of genotype approximately 24 hours after slaughter by an experienced grader. The model to analyze associations between prion protein (PRNP) genotype and production traits was based on genotype, breed, or both as fixed effects and days on feed as a covariate. Results—Average daily gain was significantly associated with only combined codons 136 and 171. In flock 1, weaning average daily gain was significantly greater in AA136 sheep than heterozygotes; the difference between QR171 and RR171 sheep, compared with QQ171 sheep, were not significant although QR171 and RR171 sheep had higher values. However, in flock 2, average daily gain was significantly greater in AV136 sheep than AA136 sheep and in QR171 sheep than QQ171 sheep. Conclusions and Clinical Relevance—Findings suggest there is an advantage for average daily gain in lambs with an arginine allele at codon 171, but there were no other genotype effects on production traits. Thus, selection for the resistant arginine allele at codon 171 to comply with USDA scrapie eradication guidelines should not be detrimental to lamb production in commercial flocks. Effects of codon 136 on average daily gain were ambiguous.

Thirty samples of Mozzarella cheese (15 made traditionally from raw milk in Tripoli city (Libya) and other 15 imported samples sold in markets related to different brand names) were examined bacteriologically for their total bacterial count, psychrophilic count, coliform count (MPN/g), presumptive Staphylococcus aureus count, as well as enterococci count. Higher counts were found in locally manufactured Mozzarella cheese. Salmonellae were absent in all examined samples for both types, while Escherichia coli were isolated from 3 samples (20%) of locally made samples. According to the suggested Libyan Standards of such samples, most of examined locally manufactured Mozzarella cheese samples were found unacceptable.

A total of 620 egg samples from different species (chickens, ducks and ostriches) and 1615 poultry samples (chickens, ducks, pigeons, quails, turkeys and ostriches) were examined for salmonella infection. 12 salmonella isolates were obtained from the egg samples (1.9%) and 67 isolates from poultry samples (4.1%). Salmonella isolates were serotyped into S. enteritidis (25 isolates), S. typhimurium (17 isolates), S. infantis (12 isolates), S. montivideo (7 isolates), 3 isolates for each of S. rubislaw and S. cerro , 2 isolates for each of S. virginia, S. agona, S. poona, and S. derby and 1 isolate for each of S. sandiago and S. kentucky. The incidence of isolation from different poultry species was discussed in details. Antibiogram of the isolated salmonellae against 10 different antibiotics revealed that norofloxacin, ciprofloxacin, cepheridin and gentamycin gave the highest activity against different salmonella isolates while amoxicillin, tetracycline, and nitrofurantoin showed the highest resistance rate. Pathogenicity of the isolated serovars was tested in chickens. All isolates were found pathogenic with various degree of virulence. SDSPAGE protein analysis for the salmonella isolated form different poultry species revealed 12 protein bands ranged from 22-289 kDa. The differences were insufficient for reliable differentiation between the isolates and accordingly, it could be used beside other molecular techniques in differentiation between the salmonella strains.

Two experiments were carried out to evaluate the efficacy of the administration of active dry yeast and/or lactobacillus preparation (AVI-BAC), either before or after the infection with antibiotic resistant field strain of Escherichia coli O127 (E. coli O127) in controlling the severity of infection in quail chicks. The quail chicks of the different experimental groups were infected orally for two successive days with 3x107 CFU of E. coli O-127 as an individual dose. The used field strain proved to be highly pathogenic for quails. Probiotics were supplemented in the drinking water for the different treatment groups at a dose level of 0.5 gm/L. The results revealed that the inclusion of lactobacilli or active dry yeast before E. coli infection has been highly effective in reducing mortality rate, organ invasion and the number of E. coli positive quail chicks. In addition, it decreased the severity of macroscopic and microscopic lesions in different organs in the probiotic treated groups as compared to the infected controls. Lactobacilli preparations were more efficient in controlling the severity of the infection. On the other hand, the administration of yeast and /or lactobacilli after inducing E. coli infection reduced the mortality rate and the severity of lesion score in different organs but probiotics failed to protect quail chicks against the infection. It has been proved that the two probiotics have synergistic effect in controlling collibacillosis in quails.

Thirty four apparently healthy cattle (9 males and 25 females) of mixed breed (Balady X Friesen) were selected for ultrasonographic investigations in this study. Ultrasonographic measurements of vertical and horizontal diameters of kidney, the diameters of the renal parenchyma and the diameter of renal sinus were determined in the middle of right and left kidneys. Twenty nine cattle (9 males and 20 females), had normal ultrasonographic appearance of both right and left kidney while the other five cows had some pathological affections including cystic kidney and renal dysplasia in their left kidneys . The vertical diameter of the right kidney was (4.84±1.18 cm) , the horizontal diameter (9.16 ± 1.35 cm) , and the vertical diameter of the renal sinus was ( 3.54 ± 1.02 cm ) . The thickness of the renal cortex and medulla ( renal parenchyma) was (2.16 ± 0.46 cm ). On the other hand ,the vertical diameter of the left kidney was (5.89 ±1.13 cm), and the vertical diameter of the renal sinus was ( 3.83 ± 1.12 cm ). The thickness of the renal cortex and medulla (renal parenchyma) was (2.46 ± 0.35 cm ). It was concluded that the ultrasonographic values determined in this study can be used as references for the diagnosis of morphologic changes in the kidney of domestic dairy cattle

The pharmacokinetic profile of ceftiofur sodium, a third generation cephalosporin, was studied in both Friesian and buffalo calves following a single intravenous and intramuscular administration of 2.2 mg kg-1 b.wt. in a cross over study with 15-day wash out period. After i.v administration the serum concentration-time curve of ceftiofur sodium was best fitted using two-compartments open model, with distribution half-lives (t½(()) of 0.384 and 0.176 h., elimination half-lives (t½(0)) of 5.047 and 1.607 h., mean residence time (MRT) of 6.926 and 2.072 h., volumes of distribution at steady-state (Vdss) of 0.206 and 0.134 L kg-1 and total body clearance (ClB) of 0.029 and 0.065 L kg-1 h-1 in Friesian and buffalo calves, respectively. Following intramuscular administration, the drug absorbed with half-lives of absorption (t½(ab)) of 1.010 and 0.217 h., maximum serum concentrations (Cmax) of 5.539 and 9.663 g ml-1 which attained after (tmax) of 3.147 and 0.825 h. and the drug was eliminated with half-lives (t½(el)) of 5.239 and 1.750 h. in Friesian and buffalo calves, respectively. The systemic intramuscular bioavailabilities were 89.82 and 99.7 %, while the in-vitro serum proteinbinding tendencies were 39.68 and 14.44 % in Friesian and buffalo calves, respectively
