Bovine leukemia virus (BLV) is the etiological agent of enzootic bovine leukosis, the most common neoplastic disease of cattle worldwide and a serious problem for the cattle industry. Previous studies have shown the molecular prevalence of BLV and the coexistence of BLV genotype-1 and -4 in Egyptian dairy cattle; however, the molecular characteristics of BLV in Egyptian beef cattle are unknown. Therefore, we collected blood samples of 168 beef cattle from slaughterhouses in three governorates in Egypt. Based on BLV-CoCoMo-qPCR-2 targeting long terminal repeats and nested PCR targeting the env-gp51 gene, the BLV provirus infection rates were found to be 47/168 (28.0%) and 42/168 (25.0%), respectively. Phylogenetic analysis based on 501 bp of the BLV env-gp51 gene from 42 BLV isolates revealed that at least six distinctive strains (b, e, f, g, x, and z) were prevalent in cattle across the examined regions. Furthermore, phylogenetic analysis of the 420 bp sequence of the BLV env-gp51 region of the six strains against 11 known genotypes showed that the strains b, e, f, and g were clustered into genotype-1, and strains x and z were clustered into genotype-4. Our results also indicated that strains b and x exist in both dairy and beef cattle in Egypt. The present study is the first to detect and genotype BLV among beef cattle in Egypt.  相似文献   

Relationship between angioarchitecture of the testicular artery and spermiogram parameters in Egyptian buffalo bulls (bubalus bubalis)     

Ramadan G. Sary  Ragab H. Mohamed  Karim M. Khalil  Al-Lethie A. Al-lethie  Hassan A. Hussein 《Reproduction in domestic animals》2020,55(3):343-350

The current study aimed to investigate the effect of testicular artery angioarchitecture on the spermiogram parameters in Egyptian Buffalo bulls. Eight adult buffalo bulls aged between 2 and 8 years were used for semen evaluation. For anatomical studies, the masculine gonads were collected after slaughtering 30 adult bulls and prepared for injection by different masses (Urographine^®, Latex and Epoxy) through the testicular artery. The mass activity of the ejaculate was assessed immediately after collection. The sperm motility in fresh bull ejaculate was more than 80%. The overall mean percentage of sperm abnormalities was <18%. The recorded sperm abnormalities were mostly secondary one including distal protoplasmic droplet, fragmented tail, detached head, detached galea capitis and bent tail. The highest percentage of sperm viability was recorded just after sperm collection (alive > 85%). The results revealed that testicular artery can be divided into three parts (abdominal, funicular and marginal parts) along its course. The coils of the funicular part forming a cone-like structure with its base fixed to the head of the testis. Two epididymal branches to the head and tail of epididymis emanate from the funicular part which continues as pars marginalis on the lateral surface of testis before its division into the lateral and medial testicular arteries on approaching the tail extremity of the testis. The increase in the length of the testicular artery with increase in the size of the testes played a great role in the degree of complexity of the architectural vascular patterns. The degree of complexity is affected by the number of coils formed by the vessel. The increase in the convolutions of the vessel will reduce the speed of blood flow to the gonads. Thus in turn will enabling the thermoregulatory mechanism to work more efficiently and will affect the semen value.  相似文献   

Growth performance,tissue precipitation,metallothionein and cytokine transcript expression and economics in response to different dietary zinc sources in growing rabbits     

Fardos A. M. Hassan  Asmaa T. Y. Kishawy  Amira Moustafa  Elshimaa M. Roushdy 《Journal of animal physiology and animal nutrition》2021,105(5):965-974

The impact of different dietary zinc sources on the growth, serum metabolites, tissue zinc content, economics and relative expression of cytokine and metallothionein genes was evaluated in this study. A total of 120 35-day-old male New Zealand White (NZW) rabbits were randomly distributed into four dietary experimental groups with 10 replicates per group and 3 animals per replicate. The control group was fed basal diet with a Zn-free vitamin–mineral premix; the other three groups received control basal diet supplemented with 50 mg/kg level with zinc oxide (ZnO; as inorganic source), Zn-methionine (Zn-Met; as organic source) and zinc oxide nanoparticles (nano-ZnO). The results indicated that Zn-Met and nano-ZnO groups significantly improved body weight, daily weight gain (DWG), feed conversion ratio (FCR) and nutrient digestibility, as well as decreased mortality, compared to ZnO and control groups. Zn-Met and nano-ZnO significantly reduced serum total cholesterol but did not affect serum proteins and liver function. Nano-ZnO supplemented group also recorded the highest value of serum alkaline phosphatase (ALP), insulin-like growth factor (IGF-1) and lysozymes compared to other groups. Nano-ZnO supplementation had increased hepatic Zn and Cu content and decreased faecal Zn content. Also nano-ZnO group recorded higher expression levels of genes encoding for metallothionein I and metallothionein II, interleukin-2 and interferon-γ in the liver of rabbits. The findings of this study demonstrated zinc nanoparticles, and organic zinc supplementation had improved growth performance and health status of growing rabbits than inorganic zinc oxide.  相似文献   

Ultrasonography and surgical management of a perineal hernia in a donkey     

F. A. Torad  A. M. Abu-Seida  A. A. Shamaa  E. A. Hassan  A. I. Abdelgalil 《Equine Veterinary Education》2021,33(9):e313-e316

This case report records a unilateral perineal hernia in a 7-year-old female donkey. The donkey had a history of unilateral swelling lateral to the left vulvar lip and difficulty in defaecation. Upon palpation, the swelling was painless, soft and reducible. Ultrasonography revealed a hyperechoic hernia sac containing dilated nonmotile bowel with homogenous hypoechoic contents. Primary herniorrhaphy was performed after repositioning of the herniated bowel. The donkey made an uneventful recovery with no recurrence or complications for 6 months of available follow-up. In conclusion, perineal hernia should be considered in the differential diagnosis of perineal swellings in donkeys. Clinical examination, ultrasonography and surgical exploration are valuable for definite diagnosis of perineal hernia in donkeys. Surgical herniorrhaphy was successful in correcting the problem in this case.  相似文献

ObjectiveTo evaluate the cyclooxygenases (COX) inhibition, adverse effects and analgesic efficacy of dipyrone or meloxicam in cats undergoing elective ovariohysterectomy.Study designProspective, blinded, randomized, clinical study.AnimalsA total of 30 healthy young cats.MethodsThe cats were randomly assigned to three postoperative groups: D25 (dipyrone 25 mg kg^?1 every 24 hours), D12.5 (dipyrone 12.5 mg kg^?1 every 12 hours) and M (meloxicam 0.1 mg kg^?1 every 24 hours). In the first 24 hours, the drugs were administered intravenously (IV), and then orally for 6 (dipyrone) or 3 days (meloxicam). Prostanoids thromboxane B₂ and prostaglandin E₂ concentrations served as indicators of COX activity and, with physiological variables and pain and sedation scores, were measured for 24 hours after first analgesic administration. Rescue analgesia (tramadol, 2 mg kg^?1 IV) was provided if Glasgow feline composite measure pain scale (CMPS-Feline) ≥5. Laboratory tests included symmetric dimethylarginine and adverse effects were evaluated regularly up to 7 and 10 days after surgery, respectively. Parametric and nonparametric data were analyzed with two-way anova and Kruskal-Wallis tests, respectively (p < 0.05).ResultsIn the first half hour after analgesic administration, COX-1 activity was close to zero and remained significantly lower than before drug administration for 24 hours in all groups. The inhibition of COX-2 activity was significant for 30 minutes in all groups and up to 4 hours in group M. No alterations in laboratory tests or significant adverse effects were observed. Pain scores and need for rescue analgesia did not differ statistically among groups.ConclusionsDipyrone at both doses and meloxicam provided a nonselective inhibition of COX-1 and -2 activities and effective analgesia without causing significant adverse effects or laboratory tests alterations.Clinical relevanceDipyrone at both doses provides equally effective analgesia without causing adverse effects in cats undergoing ovariohysterectomy.  相似文献   

Case–control study on risk factors associated with Brucella Melitensis in goat farms in Peninsular Malaysia

Caprine brucellosis is a bacterial zoonotic infection affecting goats especially in developing countries all over the world. In Malaysia, the risk factors associated with this infection in farms have not been studied. A case–control study was carried out in goat farms in four states of Malaysia to elucidate the risk factors associated with the infection on the farms using structured questionnaires and face-to-face interviews. Results indicate that the introduction of new animals (OR?=?5.25; 90 % CI?=?1.46, 18.88), younger age category of farms (OR?=?5.53; 90 % CI?=?1.09, 21.66), and farms with single breed of goats (OR?=?8.50; 90 % CI?=?1.27, 41.97) were significant risk factors for brucellosis. In order to control brucellosis or possibly eradicate it in goat farms, these factors need to be dealt with. Enforcing stringent importation protocols or complete ban of goat importation from brucellosis endemic countries will help reduce risk of introducing new infection into the country.  相似文献

A survey of gastrointestinal parasitic infection as determined by faecal examination was conducted among domestic and wild birds in Bangladesh. Birds were sampled from households, wet markets and wetlands in Chittagong and Greater Sylhet districts during April 2012 to February 2013. Mist nets were used to catch resident wild and migratory birds. The overall prevalence of parasitic infection ranged among locations from 25 to 55% in indigenous domestic ducks (live bird samples = 304), 20% in resident wild birds (environmental faecal samples = 40) and 40% in migratory birds (live bird samples = 35). The prevalence of parasitic infection was significantly higher in indigenous domestic ducks collected during summer (39%) than winter (22%) (p = 0.04). In domestic indigenous ducks and Muscovy ducks, both single and multiple types of parasitic infections were found. However, other domestic birds and wild birds often had a single type of parasitic infection. Ascaridia spp. with an average egg load of 50–900, was commonly detected in faecal samples of domestic and wild birds in this study. Other identified parasites were Capillaria spp. and Heterakis spp. both in domestic and wild birds. Improvement of biosecurity measures for household duck farms through educating and motivating household farmers could help mitigate the effects of parasitic infection on production.  相似文献

Habib ul Hassan  Waheed Murad  Akash Tariq  Ashfaq Ahmad 《Irish veterinary journal》2014,67(1):6

Background

The Malakand valley of District Dir (Lower) is endowed with a diverse plant wealth. Ethnoveterinary knowledge provides the traditional medicines of livestock that are cheaper than standard treatment and are easily accessible.

Methods

The present study was conducted to document the traditional knowledge of ethnoveterinary practices in Malakand valley, District Dir (Lower). Data was collected from February 2012 to January 2013 by interviewing 120 inhabitants through semi-structured questionnaires. Different questions were asked to collect appropriate data regarding the use of plants for livestock treatment. Direct matrix ranking (DMR) was carried out to find out the use diversity of medicinal plants.

Findings

A total of 28 plants belonging to 23 families were collected and identified for the treatment of livestock in the study area. Majority of the plants were collected from wild (68%) habitat and very few from cultivated sources. The leaves (28%) were identified as the major plant part for herbal preparations. The most frequent ailments of livestocks in the study area were stomach disorders and Charmaikh (local disease name). Various ingredients were used along with ethnoveterinary medicines i.e. sugar, flour, milk etc. The elder people of the village had a rich knowledge as compared to the young generation. According to DMR output, Monotheca buxifolia ranked first and Dalbergia sisso and Melia azedarach ranked second due to high multipurpose uses among all species and was found most threatened in the study area.

Conclusion

It has been concluded that the native of the region heavily dependent on medicinal plants for the treatment of variety of livestock ailments. Traditional knowledge always provides a baseline for further phytochemical and pharmacological investigation. The documentation of the ethnoveterinary practices in study area was necessary before this precious knowledge is lost forever due to rapid socioeconomic, environmental and technological changes.  相似文献
