The objective of this study was to evaluate the effect of exogenous fibrolytic enzyme (EFE) and/or live yeast culture supplementation in total mixed ration (TMR) on rumen fermentation patterns in buffalo. For this, four adult buffalo bulls weighing 377.05+/-43.36 kg were randomly allotted to four dietary treatments viz., TMR containing R:C ratio of 70:30 (T1), T1 supplemented with EFE at 15 g/animal/day (T2), T1 supplemented with live yeast culture at 10 g/animal/day (T3), and T1 supplemented with EFEs at 15 g/animal/day and live yeast culture at 10 g/animal/day (T4). Rumen liquor from the fistulated animals was collected at 0, 1, 2, 4, 6 and 8 h post-feeding, and was analyzed. This study revealed that rumen pH values were highest at 0 h, and were declined to minimum by 4 h post-feeding, while total volatile fatty acids (TVFA), ammonia nitrogen (NH3-N), and nitrogen (N) fractions reached to peak at 4 h post-feeding, and later followed a decreasing trend in all the treatments. Supplementation of EFE in TMR (T2 and not;) had no effect (P>0.05) on rumen pH and food and protozoal N concentration, while it influenced to increase (P<0.01) the concentration of TVFA, NH3-N and other N fractions as compared to the T1. Yeast culture supplementation in TMR (T3) increased (P<0.01) rumen pH, TVFA, NH3-N, total N, TCA-insoluble N and residual N. However, no effect (P>0.05) on food and protozoal N in buffalo bulls was found. This study indicated that, supplementation of EFE and/or live yeast culture in TMR (T4) increased (P<0.01) the rumen pH, TVFA, NH3-N and N fractions in buffalo bulls as compared to the control group. Therefore, it is concluded that supplementation of EFE and/or live yeast culture in TMR can increase the concentration of rumen metabolites in buffalo bulls.

Forty adult Friesian cows were presented to the University Veterinary Hospital, Universiti Putra Malaysia with primary complain of lameness. Upon physical examination of the cows, open wounds were found at the distal limbs, dorsal hoof, knee joint, metacarpal region, and udder. Based on history, clinical observation and physical examination, the cause of the lameness was diagnosed as of non-infectious origin; the cattle were affected with chemical burn originated from exposure to lime. The affected cattle were treated similarly to that of the line of open wound treatment; the wound was cleaned with topical application of the mixture of dermapred-iodine-benacillin. Flunixin meglumine dosed at 2.2 mg/kg bwt and Oxytetracycline dosed at 20 mg/kg bwt were given intramuscularly as anti-inflammatory and prophylactic antibiotic, respectively. This case report describes diagnosis of the cause of lameness, and its management in cattle herd caused by lime toxicity for the first time in Malaysia.

The study aimed for the detection and serotyping of Foot and Mouth Disease virus (FMDV) circulating in Kapasia Upazila, Gazipur district of Bangladesh during 2013. Twelve samples comprising of tongue epithelium (n=8) and inter digital tissue (n=4) were collected from suspected cattle, and inocula were prepared. The inocula were inoculated into confluent BHK-21 cell line for virus propagation. After 3 subsequent passages; progressive cytopathic effects (CPE) specific for FMDV i.e., rounding and flattening of cells, breaking down of the intercellular bridge and finally cell death (almost 100%) were observed; these were indicative of successful virus propagation in the cells. Viral RNA was extracted, and Reverse Transcription Polymerase Chain Reaction (RT-PCR) was performed using three sets of primers corresponding to the serotype and lsquo;O', and lsquo;Asia-1' and and lsquo;A', respectively. Out of the 12 samples, 10 (83.33%) were found to be positive for FMDV, and all of those were of serotype and lsquo;O'. It is concluded that FMDV serotype and lsquo;O' is circulating among the cattle of Gazipur district, Bangladesh. [J Adv Vet Anim Res 2015; 2(3.000): 291-295]

The present work aimed to observe the infection pattern of Bovine herpes virus-1 (BoHV-1) in dairy cattle with reproductive problems in Sudan. A total of 140 samples comprising of vaginal swab (n=97), placenta (n=15), whole blood (n=19), uterine fluid (n=1), and serum (n=8) were collected from 16 dairy herds showing particularly high rate of abortion and infertility in Khartoum State. The samples were used for virus isolation, and were tested by Enzyme-Linked Immunosorbent Assay (ELISA) and polymerase chain reaction (PCR). No virus could be isolated from the samples inoculated for isolation in cell culture. Out of 80 specimens tested by ELISA, 7 (8.75%) were found to be positive, and one sample was doubtful. Using PCR, 11 (10.7%) out of 103 samples were found to be positive. When comparing between two methods for DNA extraction, the DNA extracted by commercial kit was found to be better in quality as compared to the DNA extracted using phenol/chloroform/isoamyl-alcohol method. The study confirmed the presence of BoHV-1 in cattle farms with reproductive problems in Sudan.

The influence of two extraction solvents (ethanol and acetone) and two extraction techniques i.e., hot extraction at 400C and cold extraction at 260C were investigated on the phenolic content and antioxidant activity of extracts from Tamarindus indica seed. The antioxidant activity of T. indica was determined by evaluating 1,1-Diphenyl-2-picrylhydrazyl (DPPH) scavenging activity, ferric reducing power assay (FRAP) and ascorbic acid equivalent content (AAC). The tested sample showed appreciable amounts of total phenolic contents (51.45-71.68 mg GAE/gm of dry extract), DPPH scavenging capacity (61.18-71.17%), IC50 values (98.30-248.60), reducing power (0.6377-0.7702) and total antioxidant capacity (22.75-43.80 AAE/gm) at different solvents and techniques. Current study data shown higher extract yields, phenolic contents, scavenging activity, reducing power and antioxidant activity using ethanol solvent compared to the respective acetone solvent. In addition, higher extract yields and other properties were obtained by hot extraction at 400C compared to the cold extraction at 260C. Present study suggests that ethanol as a solvent and hot extraction technique could be better to preserve the antioxidant properties of tamarind seed. [J Adv Vet Anim Res 2015; 2(3.000): 332-337]

To explore the expected role of Bovine Viral Diarrhea Virus (BVDV) in pneumonia in cattle, cattle lungs (n=242) showing signs of pneumonia were collected from slaughter houses of three different localities located at Northern, Central and Western Sudan during 2010–2013. The collected samples were tested for the presence of BVDV antigen using Enzyme-Linked Immunosorbent Assay (ELISA), and Fluorescent Antibody Test (FAT). Twenty six (10.7%) out of 242 samples were found to be positive for BVDV. Positive results were seen in all the three studied areas, with the highest prevalence (16.7%; n=4/24) at Gezira State in Central Sudan. BVDV genome could be detected in all ELISA positive samples. The results indicated the existence of BVDV infection in cattle in different areas in Sudan, and its possible association with respiratory infections in cattle. Analysis using BLAST indicated that the sequence was identical to the previously reported BVDV-1 (GenBank accession AF220247.1.); nucleotide A was found in our study at position 9 of our sequence, whereas T was present instead in the reference virus. This is the first report of detecting BVDV antigen, genome, and its sequence analysis collected from cattle lungs in Sudan.

Pasteurella multocida type A is the etiologic agent of fowl cholera, a highly contagious and fatal disease of chickens. The present research work was performed for the isolation, identification and molecular detection of P. multocida Type A from chickens. Liver, heart and spleen of suspected dead chicken (n=35) were collected from Gazipur and Pabna districts in Bangladesh. The targeted bacteria from the samples were isolated, identified and characterized based on their morphology, staining, cultural, biochemical characters, pathogenicity test, histopathological study and Polymerase Chain Reaction (PCR). The P. multocida organism was isolated from 11.42% (n=4/35) samples. The organisms were gram negative, non-spore forming rod, non-motile, occurring singly or pairs in Gram staining, whereas in Leishman's stain, bipolar shaped organisms were observed. All the isolates were found positive for oxidase and catalase tests, produced indole, and fermented glucose, mannitol and sucrose. Necrotic foci in liver and congestion with hemorrhages in heart were found on necropsy. After pathogenicity test, the pathological changes were reconfirmed by histopathology depicting congestion, hemorrhage and lymphocyte infiltration in heart, liver and spleen tissues. In type specific PCR reaction, the organisms were confirmed as P. multocida Type A. In conclusion, P. multocida type A is prevalent among poultry in the studied regions; thus, care must be taken to control of the disease. [J Adv Vet Anim Res 2015; 2(3.000): 338-345]

The study was intended for identification and characterization of Staphylococcus aureus isolated from raw cow milk. A total of 47 milk samples were collected from Sheshmore, Shutiakhali and Bangladesh Agricultural University Dairy Farm, Mymensingh. Using bacteriological, biochemical and PCR-based identification schemes, 12 (25.53%) isolates were confirmed as S. aureus. All the isolates showed β-hemolysis on 5% sheep blood agar. S. aureus specific nuc gene (target size 279-bp) was amplified in the cases of all isolates. The isolates were found as resistant to Penicillin (100%), Erythromycin (75%) and Amoxicillin (100%). On the other hand, the isolates were sensitive to Ciprofloxacin (83.33%), Oxacillin (100%), Cloxacillin (100%) and Neomycin (100%). The isolated S. aureus showed increased resistance to broad spectrum antibiotic (e.g., Ciprofloxacin). As many people have a tendency to drink raw milk and raw milk products, there is high risk of S. aureus infection in human.

2015
Mohammad Khezri
Bovine viral diarrhea (BVD) is one of the most important diseases of cattle responsible for major economic losses in dairy industries of Iran. So far, no nationwide program has been taken in Iran to control and eradicate the disease. Moreover, until now, no vaccination program has been practiced against BVD in Iran, although the disease is prevailing in the country. For effective controlling of BVD, it is necessary to cull the affected animals, and new entry of BVD in the farm should be prevented. Focusing on biosecurity in systematic control programs of BVD can also reduce the risks of introduction and spread of other epizootic and zoonotic diseases, thereby improving both cattle health and welfare in general. In this review paper, an overview on BVD emphasizing on Iran perspective has been discussed focusing on clinical manifestations of BVD, routes of transmission of BVD virus (BVDV), its diagnostic methods and possible prevention strategies.

2015
Sirigireddy Sivajothi | V. C. Rayulu | Bhavanam Sudhakara Reddy | Karumuri Nalini Kumari
Animals affected with Trypanosoma evansi show rare serum hormonal disturbances. One of the important hormones for livestock is thyroxin, and the level of thyroxin may be reduced during the T. evansi infection. The objective of the study was to investigate thyroxin level during experimentally induced T. evansi infection in Wister albino rats. Wistar albino white rats (n=12) were challenged with the local strain of T. evansi (at 5x105 trypanosomes/animal subcutaneously). At the high parasitemia, blood was collected from the rats, and serum was separated, which was subjected for biochemical evaluation. Decreased total serum thyroxin (2.91 ±0.04 µg/dL) and free thyroxin (1.30 ±0.05 ng/dL) levels (p<0.01) were recorded in T. evansi infected rats as compared to the control group of rats. Along with lowered thyroxin levels, decreased levels of total erythrocyte count, packed cell volume, hemoglobin, total leucocyte count, total serum proteins, albumin and glucose levels were recorded. On the other hand, significant increase (p<0.01) in cholesterol, blood urea nitrogen, serum alkaline phosphatase, serum aspartate aminotransferase, and serum alanine aminotransferase levels were observed. Thus, it is concluded that trypanosomiasis induces stress on rat, which have direct effect on thyroid hormone.
