Objective: The objective of this study was to characterize Kacang goats (aged 12 years) in the highland (group 1) and lowland (group 2) areas of Jambi Province based on their body measure¬ments and body indices. Materials and Methods: A total of 320 goats were collected from lowland (n = 160), and highland (n = 160) areas with sex proportions of 80 bucks and 80 does for each area. Eight body mea¬surements and 12 body indices were used to characterize the Kacang goats from different areas. Results: The research showed that each animal group had one principal component (PC) for body measurements and four PCs for body indices. Thus, the body measurement of rump height (RH) and the body indices of area index, weight index, and thoracic development were suggested as the variables to distinguish the Kacang goats from different areas. However, the canonical correla¬tion (rc) value in the study was approximately 0.30 (low). Therefore, about 59.4% (lowland) and 60.6% (highland) of Kacang goats were characterized by the body measurements, and the body indices were indicated approximately 48.8% (lowland) and 61.2% (highland) of Kacang goats. A cluster analysis of the four Kacang populations revealed that Kacang goats in this study were grouped into a first cluster (Kerinci) and a second cluster (Muaro Jambi, Batanghari, and Sungai Penuh). Conclusion: It is concluded that body measurements and body indices cannot characterize the Kacang goats from lowland and highland areas. [J Adv Vet Anim Res 2020; 7(4.000): 734-743]

Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been reported as a worldwide emergency. Due to the extensiveness of spread and death, it has been declared as a pandemic. This review focused on the current pandemic situ¬ation and understanding the prevention and control strategies of COVID-19. Data presented here was by April 3, 2020. A total of 1,016,399 cases of COVID-19 with 53,238 deaths was reported from 204 countries and territories including two international conveyances over the world. After China, most of the new cases were from Europe, particularly Italy acting as the source of impor¬tation to many of the other countries around the world. China has obtained success by ascribing control strategies against COVID-19. The implementation of Chinas strategy, as well as the devel¬opment of a vaccine, may control the pandemic of COVID-19. Further robust studies are required for a clear understanding of transmission parameters, prevention, and control strategies of SARS-CoV-2. This review paper describes the nature of COVID-19 and the possible ways for the effective controlling of the COVID-19 or similar viral diseases that may come in the future.

Victor A. Marchenko | Salavat S. Khalikov | Yury A. Vasilenko | Mikhail M. Ilyin | Irina A. Kravchenko
Objective: Solubility and bioavailability are crucial for maximizing the activity of an antiparasitic drug. This study aimed to develop a combined preparation for antiparasitic medicines using iver¬mectin (Iver), fenbendazole (FBZ), and triclabendazole (TBZ), considering their solubility, bioavail¬ability, and activity. Materials and Methods: Innovative preparations in solid dispersions (SD) were obtained using the joint mechanical processing of drug substances with polyvinylpyrrolidone (PVP) in an LE-101 roller mill. The preparations efficacy was studied in 140 sheep spontaneously infected with gastroin¬testinal Strongylata, Dicrococelium dendriticum, Moniezia expansa, and Melophagus ovinus. The preparations were given individually to the sheep in the form of an aqueous suspension orally. Their effectiveness was evaluated using intravital and postmortem parasitological examinations. Results: The results confirmed the increase in solubility of substances by 1329 times. The exper¬iments have shown the high efficacy of SD composition of FBZ/Iver/PVP (1/1/9) containing FBZ (at 3.0 mg/kg b/w) and Iver (at 0.2 mg/kg b/w) when used against gastrointestinal Strongylates and M. expansa (95.8% and 100%, respectively), to a lesser extent against M. ovinus (38.5%). The SD composition of TBZ/Iver/PVP (1/1/9) of TBZ (at 3.0 mg/kg b/w) and Iver (at 0.2 mg/kg b/w) showed a high efficacy against gastrointestinal Strongylata and D. dendriticum (96.8% and 100%, respectively) and less activity against M. ovinus (61.6%). Conclusion: The high parasiticidal activity of SD based on FBZ, TBZ, and Iver in comparison with initial substances is explained by the formation of inclusion complexes of these substances with PVP when SD is dissolved in water and the synergistic effect of the active substances of the prepa¬rations. The resulting complexes have increased solubility in water and bioavailability. The use of such an SD suggests a significant reduction in the dosages of FBZ and TBZ without losing parasit¬icidal activity. [J Adv Vet Anim Res 2020; 7(4.000): 718-725]

Azhar F. Abdel Fattah | Shereen El. Abdel-Hamid
Objective: This study was carried out to study the influence of gender, neuter status, and training method on police dog narcotics olfaction performance, behavior, and welfare. Materials and Methods: A total of 120 German Shepherds aged 13 years were used for this study. The dogs were separated into two experiments. The first experiment (32 dogs and 28 bitches) was used to study the influence of gender on olfaction and smell to narcotics in police dog perfor¬mance and training methods with behavioral problems and welfare. The second experiment (30 dogs and 30 bitches) was used to study the influence of sexual status (entire or neutered) on the smelling of narcotics in police dog performance by comparing with intact dogs and bitches. Results: We found that there were significant differences in sex in training to detect narcotics. Male German Shepherds were found to be significantly more trainable than females. Neutering causes a difference in trainability in male and female dogs. Gonadectomy had adverse effects on training. The intact male and female German Shepherds were found to be significantly more train¬able than the neutered ones, and the reward-based method was found to be significantly more trainable than punishment. Dog training methods incorporated by punishment result in pain, suf¬fering, emotional instability, symptoms of depression, aggression, unwanted barking, growling at other people, not under control all time, less trainability, increased problematic behavior, and decreased dog welfare. Conclusion: Reward-based method is associated with lower lousy behavior and dogs with good behavior, such as, attachment attention behavior, dogs under the control of handler all times, higher trainability, less problematic behavior, and increased dog welfare.

Mohammad Shah Alam | Mohammad Zahangeer Alam | K. H. M. Nazmul Hussain Nazir | Md. Abdullahil Baki Bhuiyan
Immediate after the official declaration of COVID-19 in Bangladesh on 8 March 2020, it has created public panic which results in price plummeting of the capital market and price hike of many essential commodities. Worldwide, the outbreak of COVID-19 has declared a pandemic. In response, the Government of Bangladesh has initiated some strict measures such as stopping the entry of passengers from Europe, stopping on-arrival visas and self-quarantine for 2 weeks for all passengers return from abroad. Still, many loopholes exist at the entry points of Bangladesh. Most of the people of Bangladesh are yet to aware of the consequences of COVID-19. In this backdrop, this article has attempted to create public awareness about COVID-19, providing some guidelines to restrict this deadly disease, enlisting current challenges of this disease in Bangladesh. This review would be helpful to undertake future management practices against the fearsome COVID-19 in Bangladesh. [J Adv Vet Anim Res 2020; 7(2.000): 198-208]

Objective: This paper presents the obtained result of a study that realizes to associate a set of real and imputed single nucleotide polymorphisms (SNP) genotypes to the rear udder height in Holstein cows. Materials and methods: Forty-six Holstein cows from an arid zone of Mexico were phenotyped and genotyped for this study. Blood samples were used for DNA extraction, genotyping was per¬formed with the Illumina BovineLD Bead chip which interrogates 6,912 SNPs genome-wide, and imputation was performed using the Findhap software. After QC filters, a total of 22,251 high quality and informative SNPs were inspected. Results: The results showed the detection of 76 significant SNPs throughout the complete genome. Significant SNPs fall inside 111 Quantitative Loci Traits related to protein percentage, milk yield, and fat, among others, in chromosomes 1, 2, 3, 5, 6, 9, 10, 11, 12, 13, 19, 20, 21, 23, 26, 27, and 29. Similarly, results confirm that a genotype imputation is a convenient option for genome-wide covering when selecting economic traits with low-density real SNP panels. Conclusion: This study contributes to establishing a low-cost and profitable strategy for applying genomic selection in developing countries. [J Adv Vet Anim Res 2020; 7(2.000): 234-241]

Objective: The study aimed to explore the seroprevalence of some bacterial (Brucella spp., Chlamydia abortus) and viral [Rift Valley fever virus (RVFV), foot and mouth disease virus (FMDV)] zoonoses in domestic ruminants in Medina. Materials and Methods: A total of 1,000 blood samples from 665 sheep, 228 goats, and 107 camels were collected from the central slaughterhouse, private farms, and veterinary clinics affiliated to the Ministry of Agriculture. The samples were screened using the Enzyme-Linked Immunosorbent Assay (ELISA). The results were statistically analyzed using Statistical Package for the Social Sciences version 20. Results: Brucella was found in 7.7%, 8.8%, and 6.5% of sheep, goats, and camels sera, respec¬tively. In humans, Brucella abortus and Brucella melitensis had higher frequencies in males (61.3%, 59.8%) than in females (38.7%, 40.2%). Chlamydia abortus was reported only in sheep at a rate of 0.75%. RVFV was prevalent in sheep (10.7%) and goats (17.9%). FMDV was reported in 27.8% of sheep and 7.9% of goats. There was a highly statistical significance between Brucella, RVFV, and FMDV seropositivity and locally bred animals (p < 0.01). Multiple seropositivities have been reported among sheep and goats. Brucella was commonly observed in mixed infection with other bacterial and viral agents under study. Conclusion: The surveyed viral and bacterial agents were prevalent in ruminants in the Medina region. Since Medina is an important destination for pilgrims from all over the world, therefore, an integrated approach involving strict control measures and routine vaccination programs should be adopted to reduce the possibility of global epidemics.

Ahmed A. Elsayed | Naglaa A. Gomaa
Objective: This study was conducted to establish the normal values and repeatability of pulsed-wave (PW) Doppler ultrasonographic parameters of the hepatic portal circulation in healthy dromedary she-camels. Materials and Methods: According to the American Society of Veterinary Clinical Pathology guide¬lines, the sample size and statistical analysis were followed. Ten healthy, non-pregnant, non-lactat¬ing she-camels were selected after physical, hematological, and ultrasonographic examinations. All hepatic ultrasonographic measurements were obtained from unsedated standing she-camels at the 11th right intercostal space using B-mode and PW Doppler. Results: The ultrasonographic measurements were portal vein (PV) diameter 1.76 ± 0.37 cm; por¬tal velocity 12.3 ± 3.2 cm/sec; portal area 2.05 ± 0.57 (cm)²; portal congestion index 0.16 ± 0.04 cms; and portal blood flow volume 0.02 ± 0.05 ml/sec/kg. The intra-assay coefficient of variations (CV)% of the above-mentioned variables were 5.84 ± 4.32, 12.3 ± 7.1, 10.5 ± 5.8, 14.7 ± 7.1, and 15.8 ± 12, respectively. However, the inter-assay CV% were 13.2 ± 5.9, 18.5 ± 8.4, 19.7 ± 7.6, 17.3 ± 8.8, and 31.9 ± 15, respectively. Conclusion: This study provides data that may be used as reference values for Doppler measure¬ments of the PV in she-camels, which may help diagnose some hepatic disorders in camels.

Mostrar más [+] Menos [-]Evaluation of short-term loop colostomy in dogs using conventional and supporting subcutaneous silicone drain techniques
2020
Alaa Samy | Abdelnasser Abdalla | Awad Rizk
Objective: This study aimed at evaluating the supporting and non-supporting loop colostomy techniques in dogs. Materials and Methods: In this study, 12 adult healthy mongrel dogs were used to carry out a short-term (21 days) temporary flank loop colostomy. The dogs were divided into two groups (n = 6). In the first group (Con group), conventional stoma fixation was operated without loop support. In the second group [subcutaneous silicone drain (SSD) group], an SSD was used as a supporting bridge. The stoma was fixed by a modified, interrupted seromuscular vertical mattress suture pattern. Both peristomal and stomal complications were recorded. Results: Results showed that a total of seven dogs (58%) suffered complications. There was a sig¬nificant tendency toward less peristomal (p = 0.012) and stomal complications (p = 0.001) in the SSD group. The intensity of pain was significantly (p < 0.05) different between the two groups in the first week post surgery. Comfort with stoma care was significantly (p = 0.015) better in the SSD group, experiencing the best results. Conclusion: It is concluded that an appropriate stoma location, using a soft supporting bridge, stoma fixation using modified interrupted neuromuscular vertical mattress sutures, and proper appliance fixation by adhesive tapes and a tight T-shirt may overcome the complications of short-term loop colostomy in dogs and introduce a satisfaction for stoma care.

Dae Seung Kim | Sang Hwan Kim | Jong Taek Yoon
Objective: The study of an in vitro embryosis is crucial in genetics for breed improvement and reproduction in livestock, identifying the causes of infertility, and stem cell application. Meanwhile, the problem of nucleic acid denaturation observed during embryo development is yet to be resolved. This study was set out to analyze the nucleic acid denaturation during the development of in vitro embryos. Materials and Methods: Using an in-vitro fertilization-embryo in porcine, the cell development and apoptosis were evaluated by adding rapamycin by concentration to the TCM-199 containing 10% FBS or 10% porcine follicle fluid (pFF). Real-time PCR, zymography, DNA fragment, Western blot, and immunofluorescence analysis were also carried out to determine the development rate of inner cell mass in the in-vitro fertilization-embryo. Results: The findings indicated that the addition of rapamycin to the 10% pFF group during in vitro maturation led to an increase in the rates of cleavage and blastocyst development and the expression of active matrix metallopeptidase (MMP-9), while nucleic acid denaturation was suppressed. In other words, the addition of rapamycin was found to increase the expression of MMP-2 in the inner cell mass and trophoblast, while it inhibited apoptosis. Conclusion: The addition of rapamycin influences the regulation of apoptosis and MMPs, and based on this, it is presumed to have a positive effect on blastocyst development.
