This study was aimed to determine the bioequivalence of three different preparations of florfenicol using non-drugged broiler chickens. A total of 28 broiler chickens aging 30-day were divided into four equal groups; these were Group I, II, III, and IV. The birds of Group I (for effective substance) were given intravenous (i.v.) administration of florfenicol dosed at 40 mg/kg body weight (b.wt.). The birds of Group II (for reference drug), Group III (for test-1 drug), and Group IV (for test-2 drug) received florfenicol preparations with water (dosed at 40 mg/kg b.wt.) through intracrop administration. Blood samples were collected periodically from the birds of all four groups, and blood plasma was separated. Levels of florfenicol and its metabolite (florfenicol amine) in the plasma were measured by High Performance Liquid Chromatography (HPLC). In this study, the limit of detection (LOD) for florfenicol and florfenicol amine were recorded as 0.017 and 0.78 ?g/mL, respectively. On the other hand, the recovery of florfenicol and florfenicol amine were 83.4-84.6 and 82.2-83.8%, respectively. Based on the values of area under the curve (AUC), maximum concentration (Cmax), and time to maximum concentration (Tmax), test-1 drug was found to be acceptable, whereas test-2 drug was remained below the acceptable limits (80-125%) of AUC and Cmax. Thus, it was concluded that test-1 drug was bioequivalent as compared to the reference drug.   http://dx.doi.org/10.5455/javar.2014.a28

The study was aimed to investigate the molecular epidemiology and antibiotic resistance pattern of Enteropathogenic Escherichia coli (EPEC) in bovines and their handlers in Jammu, India. A total of 173 samples comprising of 103 fecal samples from bovines (60 from cattle and 43 from buffaloes), 28 stools and 42 fingertip rinses from bovine handlers were collected during August 2011 to March 2012. The isolated 126 E. coli strains (86 from bovines and 40 from handlers) belonged to 25 different serogroups in addition to rough and untypeable strains. Using multiplex polymerase chain reaction, four EPEC strains were isolated; two each from bovines and their handlers, of which two possessed the hemolysin (hlyA) gene. The prevalence of EPEC was recorded as 1.66% (n=1/60) in cattle, 2.32% (n=1/43) in buffaloes, and 2.85% (n=2/70) in their handlers. Antibiogram studies with the EPEC revealed the presence of multi-drug resistant E. coli. The isolates were mostly resistant to Amikacin, Amoxicillin, Cefixime and Streptomycin, and sensitive to Chloramphenicol. This study indicates that bovines as well as their handlers in Jammu region harbor EPEC, many of which being multi-drug resistant and carrying the hemolysin gene could be of high pathogenic potential for humans.  http://dx.doi.org/10.5455/javar.2014.a30

The aim of this study was to determine the effect of parenteral gibberellic acid (GA3) and/or vitamin D3 supplementation in diet on egg quality and blood physiological characteristics in aged laying hens. A total of 270 Lohmann Brown Classic laying hens aging 73-week were randomly assigned to equal three treatment groups (T1, T2 and T3) with equal 3 replicas in each group. The birds of group T1 (control group) were injected subcutaneously (SC) with sesame oil at 0.2 mL/kg body weight. The birds of group T2 were given with GA3 at 400 ?g/kg b.wt., SC, whereas group T3 had diet containing vitamin D3 at 500 IU/kg feed. Relative weight of albumen and egg shell, Haugh unit, shell thickness, serum glucose, serum calcium, serum phosphorous, serum estradiol, and bone calcium absorption were significantly increased in the birds of group T2 and T3. On the other hand, relative weight of yolk, yolk cholesterol, and serum cholesterol were significantly decreased in group T2 and T3 as compared to group T1. However, serum protein and albumen were unaffected in the treatments. In conclusion, the parenteral GA3 and vitamin D3 supplementation in diet could improve egg quality traits and serum blood biochemical perperties in agend laying hens. http://dx.doi.org/10.5455/javar.2014.a39

The aim of this study was to determine the reproductive parameters of sows in selected area of Bangladesh. A total of 51 sows from 21 farms were selected for this study. The data on reproductive parameters were collected from the owners by interviewing with pretested questionnaire. We found that the age at puberty, estrus cycle length,  estrus duration, interval between farrowing and onset of estrus and gestation length were 254.5±34.4 and 21.2±1.2 days,  34.2±13.2 h, 51.8±10.9 and 114.3±0.9 days, respectively. The number of required services for each pregnancy in native sows was 1.4 ±0.6, and the first service pregnancy rate using natural mating was 63.8%. Moreover, the number of piglets born per sow was 7.6±3.4. The highest piglet production (10.6±3.1) was in parity 5 and the lowest (4.1±0.6) was in parity 1. Estrus was detected in 34.1% sows on the basis of observing standing reflex when boar mounted. In conclusion, reproductive parameters in native sows of Bangladesh need to be improved for ensuring satisfactory reproductive performances. http://dx.doi.org/10.5455/javar.2015.b55

A female Labrador dog presented with a history of distended abdomen was subjected for clinical, physical, hemato-biochemical, eletrocardiographic, and ultrasonographic evaluations. Respiratory distress, weakness, fluid thrill on palpation of abdomen, cough, cyanotic tongue, and syncope were the significant manifestations. Elevated levels of creatine kinase, lactate dehydrogenase, alanine amino transferase, and alkaline phosphatase with normal blood urea nitrogen and creatinine were the common serum chemistry findings. Low voltage QRS complexes were the electrocardiographic abnormalities. Classical ground glass appearance of abdomen, and enlarged heart with increased sternal contact were the radiographic findings of abdomen and thorax. Ultrasonography of abdomen revealed floating viscera in the anechoic effusion with engorged and distended hepatic vasculature. 2-dimensional echocardiography revealed dilated right ventricle both on B- and M-mode. Further, insufficiency in mitral and tricuspid valves were recorded on pulsed and color flow Doppler. Hence, right heart failure due to ascites was confirmed, and the condition was successfully managed with losartas, spiranolactone, co-enzyme Q10 and tricholine citrate, and sorbitol.DOI: http://dx.doi.org/10.5455/javar.2014.a15J.

A case of Trypanosoma congolense savannah type infection in a 4-year old German shepherd dog weighing 26-kg was presented to the Small Animal Clinic, University of Nairobi, Kenya, with the history of anorexia and difficulty in breathing. The clinical manifestations were fever, pale mucous membrane, dyspnea and wasting. Blood examination revealed the existence of trypanosome parasites, and showed mild anemia. Internal Transcribed Spacer (ITS) based polymerase chain reaction confirmed the presence of Trypanosoma congolense savannah type. Along with supporting therapy, the case was successfully managed using diminazene aceturate injection (dosed at 3.5 mg/kg body weight) through intramuscular route. Complete recovery of the case was observed on day 6 of post-treatment. http://dx.doi.org/10.5455/javar.2014.a33

The aim of current study was to assess the seroprevalence of Neospora (N.) caninum and Toxoplasma (T.) gondii infections in aborted cattle and subsequent estimation of role of these parasites in cattle abortion in Hamedan province, Iran. Blood samples (n=85) of aborted cattle were collected from different locations of Hamedan province for a period of two years from January, 2010 to December, 2012. All the samples were evaluated for the presence of IgG-antibodies against N. caninum and T. gondii using Enzyme Linked Immuno Sorbent Assay (ELISA). The results showed that 61.2% (n=52/85), 5.9% (n=5/85) and 3.5% (n=3/85) animals were positive for N. caninum, T. gondii and co-infection of these two, respectively. There was no significant correlation between seroprevalence rates, age groups and breeding (p>0.05). However, a significant difference was found between T. gondii infection and the type of cattle (p=0.05), unlike to N. caninum (p=0.52). This is the first report of N. caninum and T. gondii co-infection in cattle in Iran. Although the rate of T. gondii infection was lower but this parasite might partly be responsible to be transmitted to humans. Further investigations and appropriate control strategies in management of cattle farms are highly recommended. DOI: http://dx.doi.org/10.5455/javar.v1i2p32-35 J. Adv. Vet. Anim.

Hibiscus (H.) sabdariffa (commonly known as “Karkadeh” in Arabic) is widely used in various pharmacological applications in Sudan. The present study was carried out to investigate the anti-inflammatory and analgesic activities of H. sabdariffa seed extracts using rat models. In acute anti-inflammatory models, oral administration of petroleum ether extract of H. sabdariffa seeds inhibited the hind paw edema (p<0.01) which was induced by carrageenan. The petroleum ether extract exhibited significant (p<0.01) inhibition of vascular permeability in rats induced by intraperitoneal injection of acetic acid (0.6%). In cotton pellet granuloma method, the petroleum ether extract of H. sabdariffa seed showed significant inhibition of granuloma. The extract reduced (p<0.001) abdominal constrictions which was induced by injection of acetic acid (0.7%). Analysis of seed oil of H. sabdariffa using Gas Chromatography revealed the presence of three fatty acids; these were linolelaidic acid, arachidic acid, and palmitic acid. In conclusion, H. sabdariffa seeds possess anti-inflammatory and analgesic activities in rat model.DOI: http://dx.doi.org/10.5455/javar.2014.a13 J. Adv. Vet. Anim. Res., 1(2): 50-57, June 2014

The study was conducted in Mokwa, Nigeria, to estimate the live body weight (LBW) of Nigerian breeds of sheep using cannon bone length (CBL), and other linear body measurements (LBM). A total of 116 sheep were measured for LBW and LBM. The animals were categorized into two sex groups as male and female, and four age groups as <12 months, 13-24 months, 25-36 months and ?37 months. The current findings showed that in almost all the age groups, the chest depth and heart girth alone or in combination gave the best fitted prediction equation(s). However, the CBL negatively correlated with LBW in the male and female (combined) of <12 months age group, and positively correlated with LBW in the age groups of 25-36 and ?37 months. http://dx.doi.org/10.5455/javar.2014.a29

NOTE: On 05/01/2015 The first author, Ozkan Simsek, was added to the website. This author was already on the PDF.The purpose of the present study was to determine the changes in selected hematology and serum biochemistry of Angora cats (Felis catus) during growth period. A total of 32 Angora cats (16 adults and 16 kittens) were used in this study. Blood samples were collected from the animals, and were analyzed for white blood cells, red blood cells, hemoglobin, packed cell volume, mean corpuscular volume (MCV), mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, granulocytes, monocytes and lymphocytes numbers. In the serum, alanine aminotransferase, aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), creatinine kinase (CK), total cholesterol, glucose, triglyceride, urea, creatinine, total protein, albumin, Ca, Mg, Pi levels were determined. Monocyte level was found higher, and ALP, LDH, CK activities and Pi levels were lower in adult cats as compared to the kittens. MCV was lower and GGT and AST activities, and glucose level were higher in kittens of 1.5-3 months old than in kittens of >3 months. Concentrations of total cholesterol and Mg were higher in kitten (1.5-3 months old) than in adult cats. In conclusion, age related effects on hematological and biochemical blood parameters have been determined for the first time in Angora cats. http://dx.doi.org/10.5455/javar.2015.b42
