Objective: The increase and prevalence of multidrug-resistant bacteria in livestock animals are serious public health concerns. This study aimed to identify the presence of the blaTEM gene in extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli isolated from rectal swabs of apparently healthy pigs in Malang District, East Java, Indonesia. Materials and Methods: A total of 120 rectal swab samples were collected from the pigs. The rectal swabs were screened for the presence of E. coli using standard microbiological identifi¬cation procedures. The Kirby–Bauer disk diffusion method identified multidrug-resistant E. coli. Five different classes of antibiotics were used to identify multidrug-resistant isolates, including Ciprofloxacin, Trimethoprim, Tetracycline, Streptomycin, and Aztreonam. Multidrug-resistant E. coli isolates were characterized for the presence of ESBL using double-disk synergy test methods. The presence of blaTEM genes was determined using polymerase chain reaction methods. Results: The results of this study indicated that 107 (89.2%) out of 120 samples analyzed were positive for E. coli isolates. A total of 32 (29.9%) E. coli isolates were identified to be multidrug-re¬sistant and further subjected to molecular testing. The molecular analysis revealed (5; 15.6%) E. coli isolates to harbor the blaTEM gene. Conclusion: The results of this study revealed that pigs and products of pork origin must be considered a source of transmission of ESBL-producing E. coli to public health important under the food chain.

Objectives: The purpose of this research was to look into the impacts after the implication of feeding broiler chickens with spirulina in arsenic-incited toxicities. Materials and Methods: Birds (n = 125) were distributed equally (n = 25) into four groups treated (T1, T2, T3, T4) and a group controlled, T0 (normal feed and water without supplement), the group taking in arsenic trioxide (100 mg/l)-induced diet (T1), and the groups T2, T3, and T4 (feed supplemented with 50, 100, and 200 mg/l of spirulina along with Arsenic Trioxide, respectively). The body weight and hematobiochemical parameters were recorded every 7 days. Results: Different growth development indicators, e.g., body weight, feed intake ratio, feed conversion ratio, depression, and skin lesions, were weak in arsenic trioxide groups and upstanding in the arsenic plus spirulina group. Over and above, the lack of body weight gain in chicken (2.7%–13.00%) in the arsenic-introduced groups given spirulina (T2, T3, and T4) overtook the mere groups exposed to arsenic, where the lack of weight gain was optimum (54.90%). Thereafter, in arsenic-instituted groups given spirulina (T2, T3, and T4), the drop in total erythrocyte count, total leukocyte count, hemoglobin, and packed cell volume values became less notable than in arsenic pollutant groups (T1, p < 0.01). Two measurable factors (serum glutamate pyruvate transaminase and serum glutamic oxaloacetic transaminase) were substantially (p < 0.01) raised in the group (T1) treated with arsenic, but in the arsenic-induced groups (T2, T3, and T4) treated with spirulina, they were elevated less. Conclusion: This study demonstrates that arsenic is a threat to poultry. However, spirulina may be advantageous for alleviating the effects of arsenic in poultry.

Objective: This study assessed the impact of fermented Averrhoa bilimbi fruit filtrate (FF) on growth, gut morphology, and meat traits of high-stocked broilers. Materials and Methods: A 2 × 2 factorial trial with stocking densities (9 or 18 birds/m2) and drinking 2% FF or plain water was conducted using 378 14-day-old broiler chicks. On day 35, samples were obtained and analyzed. Results: FF improved feed efficiency and income over the feed cost of high-stocked broilers by about 7.63% and 10%, respectively, compared to high-stocked broilers receiving only water. FF decreased duodenal crypt depth and meat water-holding capacity. Meats from high-stocked broil¬ers receiving FF showed lower cholesterol than other meats. Lower cholesterol/high-density lipo¬protein (HDL) and higher HDL/low-density lipoprotein were found in meats from broilers receiving FF. Total unsaturated fatty acid (UFA) was higher in meats of high-stocked broilers receiving FF than others. The UFA/saturated fatty acid was lower in meats of high-stocked broilers receiving plain water. High-stocked broilers given FF had higher meat n-3 polyunsaturated fatty acid (PUFA). FF enhanced meat n-6 PUFA levels. The n-3/n-6 PUFA increased with high density and drinking FF. Conclusion: Drinking FF improved gut morphology and meat qualities of broilers housed in high-density pens. FF may be an excellent alternative to improve the growth and meat qualities of broilers raised in high-density houses. [J Adv Vet Anim Res 2022; 9(3.000): 536-545]

Objective: This study assessed the bacteriological quality and prevalence of foodborne bacteria in raw broiler meat sold in Mymensingh City. Materials and Methods: Thigh and breast meat samples (n = 80) from broiler chickens were randomly collected from four live bird markets (LBM) in Mymensingh city for bacteriological analysis. To determine the bacteriological quality, a 10-fold serial dilution of the thigh and breast homogenate was made. Then, total viable count (TVC), total coliform count (TCC), Staphylococci, and Salmonella spp. counts were determined using plate count agar, MacConkey agar, Mannitol salt agar, and Salmonella-Shigella agar. Gram stain, biochemical testing, PCR assays, and cultural properties were used to identify the bacterial isolates. Results: The TVC in the broiler meat sample ranged between log10 8.30 ± 0.54 colony forming unit (CFU)/gm and log10 9.04 ± 0.26 CFU/gm. TCC was found between log10 5.53 ± 0.38 CFU/gm and log10 6.66 ± 0.80 CFU/gm. The mean Staphylococcal count was recorded between log10 4.64 ± 0.61 CFU/gm and log10 6.42 ± 0.53 CFU/gm, and the total Salmonella count ranged between log10 4.75 ± 0.08 CFU/gm and log10 5.69 ± 0.58 CFU/gm. The prevalence of Escherichia coli was the highest (43.2%), followed by Staphylococcus aureus (36.8%) and Salmonella spp. (20%), respectively. Conclusions: Data from this study indicated that the TVC and TCC of raw broiler meat sold at LBM exceed the permissible limits and are contaminated with foodborne bacteria, which might cause public health hazards.

Objective: A 35-day-long trial was conducted to compare the consequences of supplementing citric acid (CA), Spirulina platensis, and their combination as natural substitutes for antibiotic growth promoters (AGP) on the productive performance, dressing percentage, and blood serum metabolites of broilers. Materials and Methods: A total of 150-day-old Cobb-500 broiler chicks were randomly assigned to 5 dietary treatment groups, each having 30 chicks in it (10 chicks per replicate cage). The dietary groups were as follows: 1- Control (corn–soybean-based), 2- Control + antibiotic (Enrofloxacin, 10 mg/kg bodyweight), 3- Control + 1% S. platensis, 4- Control + 0.5% CA, and 5- Control + 1% spirulina + 0.5% CA. Starting from day 7 up to day 21, antibiotics were administered via water; spirulina and CA were offered via feed. Results: When compared to the control, all dietary supplements significantly (p < 0.05) improved broiler growth performance. However, dressing characteristics and serum metabolites (serum creatinine, albumin, and uric acid) were not influenced (p > 0.05) by dietary changes, except cholesterol level (p < 0.05). Supplementation with antibiotics, CA, and spirulina produced com-parable results. Among them, the CA-fed group recorded the highest live weight, weight gain, feed intake, improved feed conversion ratio, and the lowest serum cholesterol level (106.5 mg/ dl). The combination group performed better than the control, but not as well as their single supplementations. Conclusions: CA and S. platensis might both be good candidates as natural alternatives to AGP (Enrofloxacin). But, among them, CA performed better in terms of production performance.

Objectives: Streptococcus agalactiae is a zoonotic human and animal pathogen that causes global economic losses in aquaculture and fatal outcomes in Tilapia. This study aimed to identify S. agalactiae isolated from different fish sources intended for human consumption phenotypically and genotypically and to characterize the virulence-associated genes fbsA (fibrinogen-binding protein FbsA), cfb (CAMP factor), and pbp1A/ponA (penicillin-binding protein 1A). Materials and Methods: Three hundred Nile Tilapia fish (Oreochromis niloticus) were collected from different farms and retail shops in Dakahlia and Damietta, Egypt, during the summer of 2020. The samples were examined using routine phenotypic methods, then characterized using polymerase chain reaction (PCR) targeting S. agalactiae-specific dltS gene. All S. agalactiae isolates were examined for the susceptibility to ten antimicrobial agents by the disc diffusion method. The virulence-associated genes (fbsA, cfb, and pbp1A/ponA) were characterized using multiplex-PCR. Results: Streptococcus agalactiae was detected in 7% (n = 21/300) samples. The isolates showed high resistance against ampicillin and erythromycin (20/21; 95%) for each. The most predominant antibiotypes through isolates were P, CN, SXT, CRO, TE, CTX, E, AMP, at 10.5% for each antibiotype. A total of 19 (90.5%) of S. agalactiae isolates showed multi-drug resistance (MDR), and those were recovered from market Tilapia fish. The virulence-associated genes (fbsA, cfb, and pbp1A/ ponA) were identified in the S. agalactiae as 100%, 76%, and 52%, respectively. Conclusions: The MDR S. agalactiae detected in raw Tilapia fish pose a significant health hazard to consumers due to their zoonotic characteristics. [J Adv Vet Anim Res 2022; 9(1.000): 95-103]

Objective: The work aimed to assess the safety and quality of broiler meat in experimental liste¬riosis changes in storage. Materials and Methods: Ross Cobb 500 chickens (40) were divided into 4 groups of 10 animals each. Chickens from three experimental groups were infected by Listeria innocua, Listeria ivanovii, and Listeria monocytogenes. Meat samples were stored for 5 days at 0°C–4°C. Meat samples were kept in the refrigerator for 3, 4, and 5 days. Microbiological and laboratory indicators of meat freshness were found on these days as well. Results: After the slaughter of chickens with experimental listeriosis, pathological changes in mus¬cles and organs were noted against the background of fattening carcasses with a high slaughter yield. By bacterial contamination, 1 day after slaughter, the meat of chickens of the experimental groups (L. innocua, L. ivanovii, and L. monocytogenes) outperformed the control group by almost 1.9, 13.9, and 24.7 times, respectively (p < 0.05). The same trend is observed for the third, fourth, and fifth days of meat storage. To keep chicken meat fresh for 5 days, only samples from the con¬trol group stayed fresh. Conclusion: According to the total bacterial contamination, the meat of chickens of the groups L. innocua and L. ivanovii was dangerous to human health after 5 and 4 days of storage, respec¬tively. From the first day after the chickens were killed, the meat of chickens that had been infected with L. monocytogenes did not meet the requirements (up to 100 CFU/gm) and was not safe to store or eat.

Objective: There are three objectives in this study; 1) to measure the live weight of pre-and post-weaning Saanen kids; 2) to determine the growth curves between males and females pre-and post-weaning Saanen kids; and 3) to analyze the body condition score (BCS) between male and female pre-and post-weaning kids. Materials and Methods: This study included pre-weaning kids aged 1 month, as well as post-wean¬ing kids aged 3–6 months. 10 pre-weaning purebred Saanen kids (n = 5 male and n = 5 female) and 20 post-weaning Saanen kids (n = 10 male and n = 10 female) were employed in this investigation. Pre-and post-weaning kids' live weights were assessed weekly on a weighing scale, and BCS was calculated based on their body frame. In the data analysis, the two-sample t-test with Minitab Software was utilized. Results: The findings revealed that pre-weaning Saanen kids gained weight steadily from week 1 to week 6, with males being heavier than females. The p-value, on the other hand, suggested that there was no difference in live weight between pre-weaning male and female Saanen kids. Over 6 weeks of sampling, the male had a larger proportion of live weight gain (80%) than the female (75%). Meanwhile, the BCS of pre-weaning Saanen kids grew from week 1 to week 6. It is critical to account for the development of muscle mass while still evaluating the fat cover to determine whether the kids are maintaining an adequate BCS. However, the live weight of post-weaning kids was inconsequential because they were still in the growing phase. As a result, from the 1st to 6th week, post-weaning kids' body weight and BCS increased as their growth progressed. After 6 weeks of sampling, females had a higher percentage of live weight than males. This is because the kids raised on the farm do not have complete control over the environmental effects. Over 6 weeks of sampling, female post-weaning Saanen kids grew a slightly higher percentage of live weight (88%) than males (85%). Conclusion: This study conducted a direct assessment study, which monitored and determined the live weight and BCS of pre-and post-weaning Saanen kids. Pre-weaning kids' average values of live weight were calculated as insignificant at the age of 1 month. The mean live weight is most affected by milk consumption from its mothers, the management of the farm, and the environment. For the post-weaning Saanen kids, the females have a slightly higher average live weight gained for 6 weeks than the males (p > 0.05). In conclusion, the live weight changes of Saanen kids during the weaning stages are independent of the BCS. [J Adv Vet Anim Res 2022; 9(3.000): 527-535]

Objective: This research aims to examine the effect of different fermentation times on the results of scanning electron microscope energy dispersive X-ray (SEM-EDX), chemical, organoleptic, and microbiological quality of banana peel. Materials and Methods: The design in this study used a completely randomized design (four treatments and four replications). The treatments in this study were different durations of fer¬mentation of banana peels; T0 = no fermentation; T1 = 6 days; T2 = 12 days; and T3 = 18 days. The research parameters were chemical, organoleptic, microbiological quality, composition, and SEM-EDX images. Analysis of chemical, organoleptic, and microbiological quality data was done using analysis of variance, followed by Duncan's multiple range testing at the 5% significance level, while the elemental composition and SEM-EDX images were analyzed descriptively. Results: The results of the study showed that the length of fermentation had a significant effect (p < 0.05) on moisture content, ash, crude fiber, nitrogen-free extract, and all organoleptic quality variables of banana peels. Different fermentation durations had no effect (p > 0.05) on crude protein, ether extract, metabolic energy, total lactic acid bacteria, total bacteria, Gram positive or negative bacteria, and total fungi on banana peels. The analysis showed that the elemental composition of banana peels is C, Na2O, Cl, K2O, MgO, SO3, SiO2, and P2O5. Conclusion: Eighteen days of fermentation improved the chemical quality, organoleptic, microbi¬ological, elemental composition, and SEM-EDX image of fermented banana peel.

Objective: The effect of Artemisia herba-alba methanolic extract monotherapy and combination therapies on the in vitro growth of several Babesia and Theileria parasites in vitro and mice was investigated in this study. Materials and Methods: Fluorescence assay using SYBR Green I stain was used to evaluate the antibabesial efficacy inhibitory of A. herba-alba either in vitro or in vivo. Hematological parameters in the treated mice were analyzed using a Celltac MEK-6450 computerized hematology analyzer. Results: Artemisia herba-alba reduced the growth of Babesia bovis, Babesia bigemina, Babesia divergens, Theileria equi, and Babesia caballi in vitro in a dose-dependent manner. The in vitro inhibitory impact of A. herba-alba on B. divergens and B. caballi cultures was amplified when combined with either diminazene aceturate (DA). In B. microti-infected mice, a combination therapy consisting of A. herba-alba and a low DA dose inhibited B. microti growth significantly (p < 0.05) better than treatment with 25 mg kg−1 DA. Conclusions: These data show that A. herba-alba, when paired with a modest DA dose, could be a promising medicinal plant for babesiosis treatment. [J Adv Vet Anim Res 2022; 9(2.000): 267-274]
