Objective: This research was conducted to study the wound healing process of whole fruit pome¬granate extract (punica granatum) standardized with 40% ellagic acid ointment for deep sec¬ond-degree burn wound of skin in the rat (Rattus norvegicus). Materials and Methods: Powder of standardized pomegranate extract (SPE) with 40% ellagic acid was processed to become ointments. Twenty-five male rats, weighed 150180 gm at 3 months of age, were randomly divided into five groups. After anesthetized, stainless circle plate with 1 cm of diameter in 85°C was contacted firmly toward right gluteal of rat skins for 5 sec in order to create deep second-degree burn wound. Control groups consist of (T0) cream base and (T1) 1% silver sulfadiazine. Treatment groups consist of (T2) 2.5% SPE, (T3) 5% SPE, and (T4) 10% SPE. Histopathological preparation used hematoxylin-eosin stained skin samples. Histological observa¬tions were performed using the optics microscope against collagen, the number of polymorpho¬nuclear cell (PMN) infiltration, the degree of angiogenesis, and re-epithelization. The results were statistically compared between groups. Results: Microscopic observation on the wound healing process on the collagen, PMN infiltration, angiogenesis, and re-epithelization showed that topical administration of 10% SPE in burns gives the best result. This is characterized by a high density of collagen with a good arrangement, which is accompanied by a complete and mature epithelium, low number of inflammatory cells, and angiogenesis. This may be caused by the compounds in the pomegranate extract, which have the antioxidant, anti-inflammatory, and anti-bacterial effects. Conclusion: This study reveals that 10% SPE accelerates the healing of deep second-degree burn wound. Thus, pomegranate standardized with 40% ellagic acid is a promising herb for the healing of burn wound of skin. [J Adv Vet Anim Res 2019; 6(2.000): 202-207]

Objective: To explore feeding strategies and identify eventual errors that could cause poor pro¬duction and reproduction performances in dairy farms in the north of Algeria. Materials and Methods: A survey was conducted among 211 farms of different sizes, from 2014 to 2018 to compose a database that is analyzed statistically. Results: The results relative to the nutritive value of the rations showed an average dry matter intake of 15.9 ± 4.74 kg/cow/day, providing 13.2 ± 4.34 UFL (Feed Unit for Lactation) of net energy and 1306 ± 456 gm of protein digested in small intestine (PDI)/cow/day. A high proportion of concentrate intake is observed, with an average of 64.7% ± 17.4% of energy intake and 70.2% ± 16.2% of nitrogen intake. Dairy cows performances were characterized by a low milk production regarding their genetic potential (14.2 ± 4.73 kg of milk/cow/day), a calving interval > to one year (397 ± 20.4 days), though the coverage rates of their nutrient requirements reached 120%. The typology of the dietary rations allowed grouping them into three categories: deficient rations cluster (DR), correct rations cluster, and excessive rations cluster (ER). DR and ER, which are not adjusted to animals needs, were found in 57.8% of farms. Conclusion: It is obvious that the feeding management in the dairy farms in the North of Algeria is not based upon scientific achievements, contributing to relatively low performances of cows as well as to important financial losses. This finding imposes the necessity to adopt a correct and accurate rationing of animals. [J Adv Vet Anim Res 2019; 6(4.000): 567-574]

2019
Abdul Rohman
Meat-based food such as meatball and sausages are important sources of protein needed for the human body. Due to different prices, some unethical producers try to adulterate high-price meat such as beef with lower priced meat like pork and rat meat to gain economical profits, therefore, reliable and fast analytical techniques should be developed, validated, and applied for meat traceability and authenticity. Some instrumental techniques have been applied for the detection of meat adulteration, mainly relied on DNA and protein using polymerase chain reaction and chromatographic methods, respectively. But, this method is time-consuming, needs a sophisticated instrument, involves complex sample preparation which make the method is not suitable for routine analysis. As a consequence, a simpler method based on spectroscopic principles should be continuously developed. Food samples are sometimes complex which resulted in complex chemical responses. Fortunately, a statistical method called with chemometrics could solve the problems related to complex chemical data. This mini-review highlights the application of Fourier-transform infrared spectroscopy coupled with numerous chemometrics techniques for authenticity and traceability of meat and meat-based products.

Objectives: The present study was carried out to assess the antibiotic resistance and to identify the resistance genes in Escherichia coli from captive Bengal tigers at two Safari parks in Bangladesh. Materials and Methods: A number of 24 environmental fecal swab samples of Bengal tigers were collected from two different Safari parks in Bangladesh. For the isolation of E. coli, samples were submitted to a number of bacteriological screening and biochemical tests. The antibiotic susceptibility of E. coli isolates was determined by disk diffusion method. Results: Results demonstrated that 18 environmental fecal samples were positive to E. coli in bacteriological screening and biochemical test. The overall prevalence of E. coli in Bengal tiger was 75% (n = 18/24). The antibiogram study unveiled that all the isolates were resistant to ampicillin. Sulfamethoxazole-trimethoprim, nalidixic acid, and tetracycline were 89% (n = 16/18) resistant. On the contrary, 100% (n = 18/18) of the isolates were sensitive to colistin sulfate. blaTEM was detected in 78% (n = 14/18) ampicillin-resistant isolates, whereas sul2 was found in 31% (n = 5/16) of the sulfamethoxazole-trimethoprim-resistant isolates. Conclusion: This study, first time in Bangladesh, highlights a significant proportion of environmental fecal samples from captive Bengal tigers at Safari parks harboring antibiotic resistant E. coli. Transmission of resistant E. coli from Bengal tigers to humans and the environment could pose a public health risk at Safari parks in Bangladesh. [J Adv Vet Anim Res 2019; 6(3.000): 341-345]

Objective: This study was aimed at evaluating the effect of fermentation using Chrysonillia crassa and Monascus purpureus on nutritional qualities, antioxidant, and antimicrobial activities of the used rice as a poultry feed ingredient. Materials and Methods: The used rice was soaked, steamed, and spread on a tray to cool. Suspension of M. purpureus or C. crassa was inoculated on the steamed used rice, and then mixed thoroughly. Afterward, the mixture was spread out on the tray, which was then covered with an aluminum foil. It was aerobically incubated for 7 and 4 days for the M. purpureus- and C. crassa-inoculated used rice, respectively. Subsequent to sun drying, the fermented used rice was grounded and analyzed. Results: Crude protein and ash contents were higher (p < 0.05) in the used rice fermented with C. crassa or M. purpureus than in the unfermented. Conversely, carbohydrate content was lower (p < 0.05) in the fermented compared with the unfermented. Gross energy and energy from fat were higher (p < 0.05) in the used rice fermented with M. purpureus than the unfermented. Amino acids L-methionine, L-serine, L-glutamic acid, L-valine glycine, L-leucine, L proline, L-threonine, L-histidine, and L-Sistine were higher (p < 0.05) in M. purpureus-fermented used rice than in C. crassa-fermented and the unfermented used rice. However, amino acids L-isoleucine, L- alanine, L-lysine, and L-tryptophan were higher (p < 0.05) in the used rice fermented with both C. crassa and M. purpureus, compared with the unfermented. L-tyrosine content was higher (p < 0.05) in M. purpureus-fermented used rice than in the unfermented. Furthermore, the antioxidant activities of the fermented products were higher (p < 0.05) than that of the unfermented. In addition, the antimicrobial activities of the fermented products against Staphylococcus aureus were higher (p < 0.05) than that of the unfermented used rice. Conclusion: In conclusion, the used rice fermented using C. crassa and M. purpureus improved the nutritional quality, as well as the antioxidant and antimicrobial activities of the products.

Objective: The objective of the present study was to evaluate heterozygosis in cattle population, and to characterize White Fulani breed by identifying DNA markers considering microsatellites. Materials and Methods: A total of 41 cattle were randomly selected and used for sample (wool) collection for the characterization and identification of phenotypic traits of cattle in Nigeria. The DNA samples from the samples were prepared. Twelve microsatellite primers were used for the microsatellite analysis in the genomic DNA of cattle. The reinforced products were analyzed to determine polymorphic alleles and their frequencies. Results: White Fulani is characterized by a high degree of genetic diversity. The microsatellites have multiple alleles and may show heterozygosity frequencies of at least 70%. White Fulani cows and their F1 descendants form a common cluster, to which the bulls of the Kuru and Red Boro breeds are adjacent. There is a clear differentiation of purebred populations of Tajik zebu-like cattle (Q = 98.7%) and a significant proportion of white Fulani (Q = 81.8%) from Nigeria. The microsatellite analysis of zebu of Nigeria allowed identifying a total of 80 alleles. In the KURU and PAX-KR-BOR rocks, 17 and 19 alleles were identified, respectively. In F1, 51 alleles were detected. Conclusion: White Fulani cattle are characterized by a high degree of genetic diversities. This makes it a highly informative source in genetic analysis. The results can be applied in dealing with the conservation and sustainable applications of genetic resources in the Nigerian cattle population. [J Adv Vet Anim Res 2019; 6(4.000): 474-480]

Objective: The present study was aimed to evaluate dose-dependent effects of phytobiotic (Galibiotic) supplements in feed on growth performance, hematological parameters, intestinal pH, and gut bacterial population in broiler chick. Materials and Methods: A total of 50 ten day old broiler chicks were divided into five groups, namely, Group A as control (without galibiotic), Group B (galibiotic at 1 gm/kg feed), Group C (gal¬ibiotic at 2 gm/kg feed), Group D (galibiotic at 5 gm/kg feed), and Group E (galibiotic at 10 gm/kg feed). All the birds were reared for 42 days and samples were collected before and after sacrifice. Results: Live body weights showed no significant differences between the groups but overall feed conversion ratios (FCRs) of treatment groups were significantly low in Group E having the lowest. Blood samples collected for hematology differed significantly (p < 0.01) among the different groups. Intestinal pH was lower in treatment groups with Group E having the lowest. Cecal total viable count was highest in Group A and lowest in Group E. The cecal coliform count was low in all the treatment groups. Conclusion: Along with previously published report, it may conclude that the phytobiotic could be used as an alternative to antibiotics due to positive growth performance, lower FCR, carcass quality, and improved gut health of broiler chicks.

Objective: The purpose of our research was to evaluate the effect of mechanochemical technology on the efficacy of supramolecular complex of fenbendazole (SMCF) with polyvinylpyrrolidone (PVP) polymer against some helminthosis of animals.Materials and Methods: The SMCF samples with PVP were synthesized using a solid-state mechanochemical technology in activators of impact-abrading type and their physicochemical properties were analyzed. The efficacy of SMCF was studied on the laboratory model of Hymenolepis nana and Trichinella spiralis infection of mice and helminthosis of sheep.Results: In the trials conducted on laboratory models, the supramolecular complex showed 93.94% and 98.56 % efficacy at the dose of 1 mg/kg of body weight (b/w), while the substance of fenbendazole showed 7.97% and 8.33% efficacy at the same dose. A high efficacy (>94%) of the SMCF was revealed at the dose of 2.0 mg/kg of b/w at oral administration against nematodes in naturally infected sheep by the results of the fecal examination, while the substance of fenbendazole was active at the dose of 5.0 mg/kg at single oral administration. Moreover, the SMCF demonstrated 97.37% efficacy at the dose of 2 mg/kg against Moniezia spp. infection of sheep. Physicochemical studies confirmed the increase in solubility of the complex, reducing of particle sizes, amorphization of fenbendazole substance, and incorporating it with micelles of PVP.Conclusion: According to the results, supramolecular complex of fenbendazole with PVP was more active than the basic substance of fenbendazole and its anthelmintic properties were expanded.

Objective: This study aimed to measure the anthelmintic effects of betel nut (Areca catechu) and neem (Azadirachta indica) leaf extracts against Fasciola spp. in vitro in comparison with the com-mercial dewormer, Albendazole, and the negative control, nutrient broth. The study determined the extract concentration that produced the highest efficacy based on the average recorded mean motility time, gross, and microscopic changes of the flukes treated with different concentrations of plant extracts.Material and Methods: The study consisted of eight treatments. Every treatment consisted of 10%, 20%, and 40% concentrations of both betel nut extract (BNE) and neem leaf extracts, positive control treatment (Albendazole-treated) and negative control treatment (25 ml nutrient broth). The motility of the flukes on all treatments was based on the established motility criteria scoring. The flukes subjected to all treatments were processed for histopathological analysis.Results: The result of the study revealed that after exposure of Fasciola spp. under 10%, 20%, and 40% extract concentrations, betel nut showed higher efficacy having the recorded mean motility time of 0.22, 0.07 min, and no movement upon contact, respectively, than Albendazole which produced mean motility time of 0.38 min. Nevertheless, the flukes treated with 10%, 20%, and 40% neem leaf extracts obtained the average mean motility time of 220, 151, and 98 min, respectively.Conclusions: The results gathered showed that 40% BNE concentration showed the highest efficacy based on the recorded mean motility time. All treatments of betel nut extract evidently showed marked changes in the gross and microscopic morphology of the flukes. However, the neem extract was ineffective in all concentrations although changes were observed microscopically. Furthermore, the nutrient broth was proven to be effective as a culture medium since the flukes remained active until 8 h of exposure. [J Adv Vet Anim Res 2019; 6(1.000): 44-49]

Objective: This study was conducted to estimate the prevalence of Trichomonas gallinae infection in pigeon and determination of spatial factors related with T. gallinae infection among smallholder farms at Abhaynagar and Monirampur Upazillas, Jessore District, Bangladesh. Materials and Methods: This cross-sectional study has undertaken from November 24, 2017 to February 28, 2018 on randomly selected 60 pigeons from 12 smallholder farms. Wet smear technique has been used to identify T. gallinae, from swab samples collected from oropharynx and crop of the sampled birds. Results: The overall prevalence was 60% (95% CI: 46.572.4) in which 75% (95% CI: 55.189.3), 50% (95% CI: 23.076.9), and 44.4% (95% CI: 21.569.2) were in squab, adult male, and adult female, respectively. The prevalence, in the case of dead pigeons (n = 13), 69.2% showed positive to the protozoan infection in the study. On the basis of spatial distribution, T. gallinae infection in the rural area was 64% (n = 25) followed by urban area 57.1% (n = 35) of the district. The prevalence of T. gallinae was insignificantly higher at Abhaynagar upazilla in contrast to Monirampur upazilla (30%) of Jessore district. Conclusion: This research finding suggests that a significant level of (57.4%) T. gallinae infection is circulating among the pigeon population of Bangladesh. Therefore, proper housing, feeding, and disease management should be ensured by the owner to prevent this problem. [J Adv Vet Anim Res 2019; 6(4.000): 549-552]
