Objective: This study assessed traditional farmers' preferences for indigenous pigs and their awareness levels toward reproductive biotechnology. Materials and Methods: This cross-sectional, descriptive study employed a mixed-methods con¬current triangulation design with a pragmatic approach. For quantitative data collection, a ran¬domly selected sample size of 622 respondents was interviewed using a structured questionnaire. A semi-structured interview guide was used in seven focus group discussions (FGDs) for qualitative data. For quantitative data, descriptive statistics were used to find out how often something happened, and chi-square tests were used to look for relationships. For qualitative data, thematic analysis was used. Results: The majority (66.9%) of respondents were female, and they had largely (64.8%) attended a primary level of education. A slight majority (43.1%) of the respondents were 30–45 years old. Most respondents (65.1%) were low-income earners (below K500). Incidentally, the majority (74.1%) of respondents had low awareness of reproductive biotechnologies. Respondents' aware¬ness levels were associated with gender (p < 0.001), education (p < 0.001), income (p < 0.01), and not age (p > 0.05). With regard to trait preference, a total of seven indigenous pig traits were reportedly preferred, of which disease resistance (25.9%) and litter size (23.8%) were the most preferred. From FGDs, participants valued indigenous pigs, citing many preferred traits, of which disease resistance and litter size were the most emphasized traits. Some participants were aware of many reproductive biotechnologies and their perceived advantages. However, they were more familiar with artificial insemination, heat detection methods, and synchronization. Conclusions: The majority of respondents had low awareness of reproductive biotechnologies. Respondents' awareness was associated with sociodemographic characteristics. The identified indigenous pig traits preferred by traditional farmers included adaptive and productive traits.

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]

Objective: This short study describes the occurrence of pathogenic Leptospira spp. in two major wet markets in Kota Bharu, Kelantan, Malaysia. Materials and Methods: 30 rodents (20 rats and 10 shrews) were caught in 2 wet markets, and a postmortem was performed to extract both kidneys. Molecular diagnosis via polymerase chain reaction (PCR) was conducted to detect leptospiral DNA using universal and pathogenic Leptospira primers, respectively. Results: The results showed that 20/28 (72%) rat samples were detected positive for Leptospira spp, and all shrews were negative. Further sequencing analysis identified L. interrogans and L. borgpetersenii as the most frequently Leptospirosis species from kidney samples. Conclusions: The presented study here sheds light on the presence of pathogenic leptospires har¬boring the rat population in both wet markets in Kelantan, which presents a great public health risk to wet market workers and visitors.

Objective: Here, we developed and tested the efficacy of a vaccination protocol based on a commercially available live attenuated Salmonella enterica serovar Gallinarum (Salmonella galli¬narum) in layer chickens. Materials and Methods: 50 layer chickens of 16 weeks age were obtained and divided into two groups (n = 25), control and vaccinated. The vaccinated group received Salmonella vaccine at 0.2 ml/bird, s/c route at 16, 18, 30, and 42 weeks of age. At 21 weeks of age, birds from both groups were challenged with S. gallinarum orally at 4 × 107 colony-forming unit per bird. Results: Both rapid serum plate agglutination and enzyme-linked immunosorbent assay demonstrated a rising rate of seroconversion in vaccinated birds across the study period, with a 4% positive rate at 18 weeks, 56% at 21 weeks, 60% at 30 weeks, and 64% at each time point of 42 and 54 weeks. The vaccine showed 100% clinical protection and reduced the Salmonella shedding in the feces and eggs of the challenged birds. On the contrary, the unvaccinated challenged birds showed clinical signs and lesions typical of Salmonella infections with morbidity and mortality rates of 36% and 20%, respectively, and had high rates of Salmonella shedding in feces and eggs. Conclusions: With the proposed vaccination schedule Salmonella shedding was prevented, and a high seroconversion was confirmed. To prevent Salmonella infections in laying flocks, a 3-month interval immunization program is advised starting at the pre-laying stage. [J Adv Vet Anim Res 2022; 9(2.000): 301-309]

Objective: Quail production is ranked as an important alternative animal protein source in Cameroon. One of the main constraints of this production is the quality of feed, which lacks pro¬tein that is regularly supplied by fish meal. To avoid disagreements due to the constant shortage of fish meal, alternative protein sources are needed, and among them are crickets (Acheta domes¬ticus). The goal of this study was to find out how well Japanese quails could be raised if fish meal was replaced with cricket meal. Materials and Methods: A total of 192, 4-week-old quails were divided into 12 similar sets of 8 females and 8 males. The Four experimental diets (T00, T15, T30, and T45) were all formulated based on the level (0%, 15%, 30%, and 45%, respectively) of fish meal substitution with cricket meal in the basal diet (crude protein: 20.18% and ME: 3,013.78 kcal/kg) and randomly assigned to three sets in a completely randomized design consisting of four treatments each repeated three times. Growth, carcass, and some reproduction parameters were collected. The data were analyzed using one-way analysis of variance and the Duncan test, with a significance level of 5%. Results: Cricket meal diets increased body weight in males (204.32 ± 5.69 gm for T45) and regard¬less of the sex (226.72 ± 29.45 gm for T30) compared to 184.17 ± 3.11 gm and 214.55 ± 32.77 gm for the control group, respectively. In females, substitution at 30% increased body weight (253.80 ± 6.48 gm), while 45% induced a reduction (216.67 ± 6.49 gm) when compared to the control group value (244.92 ± 6.07 gm). Carcass yield and the proportion of different parts were not significantly affected by the experimental diets. Liver proportions were significantly higher at 15% and 35% cricket meal incorporation compared to 45%. First songs and egg laying were recorded at 7 weeks with T15, which also led to improved egg laying performance compared to the other treatments. Ovaries were poorly developed in the T45 females compared to the other treatments. Conclusions: Cricket flour might be a good candidate as a locally available protein source to sub¬stitute fish meal in the Japanese quail's diet at the finisher and reproductive stages, and the level of 30% seems to be more efficient.

Objective: This study aimed to determine the anticoccidial potential of Tinospora rumphii ethan¬olic stem extract, resulting in an effective reduction in oocysts per gram counts of Eimeria species in goats in comparison to the commercial coccidiostat toltrazuril. Materials and Methods: Eighteen goats that were naturally infected with coccidia were identified as experimental animals. The experimental animals were grouped and were administered a single dose of T. rumphii extract at concentrations of 300, 600, 1,000, and 2,000 mg extract/kg body weight. The fecal samples were collected before treatment, during the first treatment, and every week thereafter for 28 days posttreatment. Fecal examination was carried out using a modified McMaster technique to determine the oocysts per gram of feces, and the mean efficacies of the extracts were calculated. Results: Stem extracts of T. rumphii were able to lower the oocysts per gram count than pre¬treatment for all concentrations, but the efficacy, in general, was still lower than toltrazuril. A significant difference existed in the efficacy of the extracts among the treatments on day 14. Administering 1,000 mg/kg extract resulted in the highest efficacy rate (95.25%) at 14 days post¬treatment and was comparable to that of toltrazuril (89.89%). Conclusion: The results show that the T. rumphii stem extract has the potential to reduce the Eimeria species oocysts per gram counts of naturally infected goats.

Objective: Many bacteria are involved in causing mastitis in dairy cows. Perfect identification of bacteria is crucial for the appropriate choice of drug for treatment. This study aims to find out the various bacteria that cause mastitis through the 16S ribosomal ribonucleic acid (16S rRNA) gene. Materials and Methods: A total of 150 mastitis somatic cell samples were tested with bacterial nested polymerase chain reaction (PCR) universal primers, targeting the 16S rRNA gene. The primers had both Gram-positive and Gram-negative bacterial specificities. Inflammatory cytokine interleukin (IL-10), IL-4, and interferon-gamma (IFNγ) expression genes were measured and compared in mastitis-free and mastitis-affected animals. Results: Based on the PCR, 70 (46.7%) samples showed positive results. The expression of the IL-10 gene was significantly higher (p < 0.001) in mastitis-affected cows than noninfected animals. Compared to cows diagnosed with clinical mastitis, the IL-4 and IFNγ genes were expressed more strongly in healthy cows (p < 0.0001). Conclusion: Mastitis has been linked to both Gram-positive and Gram-negative bacteria. These genes are strong predictors of mastitis in the states analyzed, as evidenced by the differential expression in mastitis and healthy conditions of the IL-4, IL-10, and IFNγ genes. The genes examined here and others will be the subject of additional research. [J Adv Vet Anim Res 2022; 9(1.000): 42-52]

Objective: The purpose of this research is to detect the antibacterial properties of lactic acid bacteria (LAB) against pathogenic bacteria. Materials and Methods: Isolation and determination of Lactobacillus spp. Testing of the antibacterial activity of LAB was conducted using filtrate and nonfiltrate forms. The lactic acid bacterial isolates were confirmed to be identified through Gram staining, cell shape, catalase testing, and motility testing. Results: The results of the analysis of the LAB inhibition zone using filtrate and nonfiltrate forms against the bacteria Bacillus cereus were included in the very strong category. The results of the analysis of the LAB inhibitory zone using filtrate and nonfiltrate forms and the agar well method against Staphylococcus aureus bacteria were classified into the very strong category. The results of the LAB inhibitory zone analysis using filtrate and nonfiltrate forms with the well method against Escherichia coli bacteria are included in the very strong category, whereas the results from the LAB inhibitory zone analysis using the filtrate and nonfiltrate forms with the agar diffusion method (disks) are included in the strong category. Conclusion: Based on the results, LAB isolated from Sumba mare's milk displayed antibacterial activity in the strong and very strong categories against pathogenic bacteria such as B. cereus, S. aureus, and E. coli.

Objectives: The objective of this study was to evaluate the persistence of oxytetracycline (OTC) residue in common fish species (Catla, Rui, Mrigal, and Pangas) available in local fish markets and the corresponding transport water of the Mymensingh region. Materials and Methods: Live fish and corresponding transport water samples were analyzed by thin layer chromatography (TLC) and high-performance liquid chromatography for qualitative and quantitative detection of OTC residue, respectively. A total of 240 fish samples and 60 water samples were randomly collected from three local fish markets during the summer and winter seasons. Results: OTC residues were detected in 18 samples (13 fish and 5 water samples) in the summer and 8 samples (only fish samples) in the winter. The overall percentage of antibiotic residue positive in fish samples was 5.42%, and in water samples, it was 8.33%. In fish, OTC concentrations of TLC-positive samples ranged from 34.7 to 56.85 parts per billion (ppb) in Catla, 23.45–35.37 in Rui, 11.02–26.80 in Mrigal, and 10.80–77.55 in Pangas during summer. The concentrations were 18.5 ppb in Catla, 15–16.09 in Rui, 10–14.63 in Mrigal, and 21.02–40.11 in Pangas during the win¬ter season. On the other hand, the range of OTC concentrations of TLC-positive samples for water was 12.9–59.18 ppb during summer and below the detection level during winter. The highest prevalence of antibiotic residues among fish samples was found in Pangas (16.67%). The highest percentage of samples (15% in the fish sample and 30% in the water sample) found to be positive were collected from Mechua Bazar. The comparison between the summer and winter seasons showed that the percentage of positive antibiotic residue in the summer season (10.38% for fish and 16.67% for water) is higher than that of the winter season (6.67% for fish samples only). This variation indicates that fish transporters use more antibiotics during the summer than in the winter season. The difference between the means of fish species and water samples was not statistically significant (p > 0.05). In addition, no samples exceeded the maximum residue limits (MRL) of OTC (100 ppb) in fish set by the European Commission. Conclusion: Although the concentrations of antibiotic residues in fish edible tissues are below MRL values, the presence of antibiotic residues in transported water may lead to the development of antimicrobial resistance bacteria that are detrimental to humans, animals, and aquatic animals.

Objective: The main objective of this study is to design a synthetic vaccine from the binder of sperm-1 (BSP1). Materials and Methods: This study was carried out using bioinformatics-related techniques. BSP-1 has been chosen as one of the biomarkers of a ruminant's male fertility. We hypothesize that the BSP1 synthetic vaccines, which contain T-cell epitopes, can produce antibodies more effectively for the development of a sperm fertility detection kit. A sequence of BSP-1 peptides A0A0K1YXR5 from Bubalus bubalis (Domestic water buffalo) origin has been decided to be used to develop the peptide vaccine. Results: In this study, we succeeded in making synthetic vaccines from BSP-1 with a peptide sequence of LPEDSVPDEERVFPFTYRNRKHF. The three-dimensional theoretical prediction analy¬sis of the peptide binding pattern to its ligand, as well as the molecular docking, has also been revealed. Conclusions: A synthetic vaccine from the BSP-1 has been developed in this study with the amino acid sequence LPEDSVPDEERVFPFTYRNRKHF, which is buffer-soluble, and the three-dimensional theoretical prediction analysis of the peptide binding pattern of BSP-1 to its ligand, as well as molecular docking, has also been revealed.
