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.

Objective: This study focuses on the orocutaneous fistula (OCF), a pathological channel between the buccal cavity and the outer surface (skin) of the face, causing leakage of saliva and fluid from the oral cavity to the face externally and also the ectopic incisors (EIs) erupted in a rare position in a day-old calf. The surgical interventions for these congenital defects were further described in this study. Materials and Methods: The calf was presented with an abnormal and external opening in the left submandibular region, having congenitally exposed jawbone and muscles with the resemblance of a linear groove, and was clinically examined based on the problem of swallowing milk due to lateral passing out of liquid through the unnatural tract before entering into the digestive tract. Clinical observation revealed an OCF with four EIs that abnormally erupted in the externally exposed groove of the fistula. Reconstructive surgery (RS) was performed along with a thorough guided approach to repair the defect, emphasizing normal functionality of the buccal cavity connecting to the pharynx and cranial esophagus, and smooth extraction of the EIs was ensured without making any deep wound. Results: After 2 weeks of postoperative care with supportive medications, the calf was quite recovered, having no further complications in the submandibular region along with no visible defect in swallowing. Conclusion: OCF in calves can be fruitfully treated by RS before getting severely infected and complicated. Outside the oral cavity, submandibular EIs can be easily removed, ensuring no further bleeding and defect. [J Adv Vet Anim Res 2022; 9(3.000): 509-515]

Objective: This study aims to develop and validate an Attenuated Total Reflectance–Fourier Transform Infrared Spectroscopy (ATR-FTIR) spectroscopic technique combined with a partial least squares regression (PLSR) model for rapid quantification and monitoring of aflatoxins in chicken feeds and food grains. Materials and Methods: A model of ATR-FTIR-PLSR was developed using ATR-FTIR spectra of mixed aflatoxin standards in 100% acetonitrile (112 samples) and 75% methanol (112 samples), validated by testing its prediction on 125 feed/food samples spiked with variable concentrations of aflatoxins, and applied to screen 660 samples of commercial chicken feeds and food grains from Nigerian and Malaysian markets for total aflatoxins, for which the dietary exposure risks to aflatoxins (DERA) and associated hepatocellular carcinoma (HCC) risks were evaluated for both countries. Results: The ATR-FTIR-PLSR model demonstrated excellent prediction power [R2 = 99.59%, p = 0.001, root mean square error of calibration (RMSEC) = 1.69, RMSE p = 1.98, bias = −0.26], sensi¬tivity (limit of quantitation and limit of the method < 5.0 ng/gm), precision (coefficient of variation = 0.97–1.72), and accuracy (% recovery of 88%–106%) in all the spiked samples. The model's pre¬diction was statistically reliable (R2 = 99.8%, p < 0.05) when compared with a high-performance liquid chromatography method. Levels of aflatoxins in the commercial samples signify high DERA (0.92–138.2 ng of aflatoxins/kg BW/day) and HCC risk (1.07%–159.91% of HCC/100,000 people/ year) in the exposed populations. Conclusions: Results feature the conceivable implementation of the proposed ATR-FTIR-PLSR model for rapid, accurate determination and monitoring of aflatoxins in commercial chicken feeds and food grains; and the need to strengthen aflatoxin control/prevention strategies in the study populations.

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]

Objectives: The goal of this research was to figure out the effect of the local sorghum as silage on the performance of Bligon goats. Microbial protein synthesis, digestible nutrients, and average daily weight gain (ADWG) were measured to evaluate the goats' performance. Materials and Methods: The study was designed in a completely randomized design with a one-way pattern. Twelve female Bligon goats with 24.33 ± 2.83 kg (mean ± SEM) initial body weight were divided into three groups of total mixed ration (TMR) treatments. Group 1 received fresh Napier grass (FNG) as a control, group 2 received imported sorghum silage (ISS) of brown midrib resistance (BMR), and group 3 received local sorghum silage (LSS) of super-2. Analysis of variance was used to analyze the data on microbial protein synthesis and feed intake during the research. On the contrary, analysis of covariance was used to analyze ADWG with initial weight as a covariate. Results: Microbial protein synthesis, feed-intake, and ADWG of goats that received TMR based on silage of two varieties of sorghum, namely BMR (ISS) and super-2 (LSS), were lower (p < 0.05) than control. However, there was no significant difference between both TMR based on sorghum silages. ISS's feed conversion was better than LSS (p < 0.05), and FNG was the best. Sorghum silage as a basal ration in TMR had lower microbial protein synthesis but higher total digestible nutrient content than fresh forage, such as Napier grass. The sorghum varieties did not affect the microbial protein synthesis, digestible nutrients, and ADWG of Bligon goats. However, ISS treatment had higher feed efficiency than LSS. Conclusion: The local sorghum (super-2) silage can be used as ruminant feed as well as imported sorghum (BMR) offered as TMR. However, regardless of the cultivar, TMR based on sorghum silage cannot replace TMR based on fresh Napier grass. [J Adv Vet Anim Res 2022; 9(2.000): 175-183]

Objective: This study aimed to produce hyperimmune serum against genotype VII Newcastle disease virus (NDV) with several applications. Materials and Methods: Production of hyperimmune serum against genotype VII NDV was performed on eight New Zealand white rabbits divided into four groups. Rabbits were immunized three times on the 1st day, the 14th day, and the 30th day. Blood sampling was carried out on the 8th day after the third immunization. Results: All groups showed the same pattern of hemagglutination inhibition (HI) titer results. HI titers would peak on the 5th or the 9th day after the second immunization, then decrease until the 3rd day after the third immunization, and increase again on the 5th day after the third immu¬nization. Rabbits immunized intravenously showed higher HI titers than the other groups. These results indicate that the intravenous route for hyperimmune serum production against genotype VII Newcastle disease virus greatly affects the immune response result. Conclusions: The production of hyperimmune serum by intravenous immunization three times was able to produce the highest titer of 210 at 38 days. The agar gel precipitation test and the Western blot assay showed that the hyperimmune serum was specific for the Newcastle disease antigen. [J Adv Vet Anim Res 2022; 9(2.000): 211-220]

Objective: This experiment investigated the effect of microencapsulated turmeric by maltodextrin as an amorphous matrix material on the health status of broiler chickens. Materials and Methods: The broilers used were 144 healthy 1-day-old males. The average body weight was 47.8 ± 1.42 gm. The statistical design was based on a completely randomized design with four treatments and six replications. There were six broiler chickens in each experimental unit. The treatments were TM0 = 0 gm/kg of basal feed, TM1 = 1 gm/kg of basal feed, TM2 = 2 gm/kg of basal feed, and TM3 = 3 gm/kg of basal feed. The growth performance, physical traits, internal organs, microbial population, intestinal morphology, hematological parameters, and anti¬oxidant profile were examined. Results: The results reported that microencapsulated turmeric by maltodextrin as an amorphous matrix significantly improved the hematological parameters, growth performance, antioxidant profile, LAB, immune organs, and intestinal morphology. The results also show decreasing coli¬form and pH of the cecum. Conclusions: Dietary addition of maltodextrin microencapsulated turmeric of 3 gm/kg in basal feed can be used as a natural feed additive to improve the health status of broiler chickens.

Objective: The study aimed to determine the effect of Acalypha indica Linn. (AI) root extract and a combination of simvastatin–AI on improving the fatty pancreas in Sprague–Dawley rats induced with a high fructose and cholesterol diet. Materials and Methods: Twenty-four male Sprague–Dawley rats were induced with a high fruc¬tose and cholesterol diet for 4 weeks before being divided into four groups. Each group receiving treatments consisting of simvastatin only, A. indica extracts only, or simvastatin–A. indica extract combination. A histological examination was conducted to determine the effect of each treatment. Also, one-way analysis of variance (ANOVA) and post-hoc Bonferroni test were conducted to assess the comparison of groups from the histological examination. Results: Significant improvement was found in fatty pancreas between rats without therapy and rats treated with simvastatin therapy (p = 0.024, 95% CI: 0.038–0.696), and also between rats without treatment and rats treated with simvastatin–A. indica extract combination therapy (p = 0.000, 95% CI: 0.241–0.873) using one-way ANOVA and the post-hoc Bonferroni test. Conclusions: The results of the combination of simvastatin–A. indica Linn. root extracts treatment showed a synergistic effect on the improvement of fatty pancreas, but further research is needed to find potential adverse effects on the interaction of these two substrates to confirm the safe use of this treatment.

Objective: We investigated the effects of a source of selenium [inorganic or nano-selenium (nano-Se)] on female V-line rabbits with or without injection of ivermectin (IVM). Material and Methods: Eighty four rabbits (12 weeks old) were randomly divided into 4 groups of 21 rabbits each with the basal diet supplemented as per the following treatments: G1 (control): inorganic Se at 0.3 mg/kg diet with no IVM injection; G2: inorganic Se with IVM injection; G3: nano-Se with no IVM injection; and G4: nano-Se with IVM injection. IVM was injected subcutane¬ously at 0.2 mg/kg body weight starting when the does were 14 weeks old and repeated weekly for five consecutive weeks. Results: Replacement of inorganic Se with nano-Se improved body weight and total body weight gain, total feed intake, average feed conversion ratio, and reproductive performance (age at puberty, number of service/conception, conception rate, number of kits/litter, and lit¬ter weight at birth). Similarly, sexual activity of does, serum estrogen levels, and serum levels of antioxidants (glutathione reduced, catalase, and malondialdehyde) increased in nano-Se-sup¬plemented groups. Ivermectin treatment in inorganic Se-supplemented groups was detrimental to growth and reproductive performance, while these parameters improved in IVM-treated and nano-Se-supplemented groups. Conclusion: Nano-Se mitigated the negative effects of IVM treatment on the growth and repro¬ductive performance of does. [J Adv Vet Anim Res 2022; 9(1.000): 128-137]

Objective: The information about risk factors for a high stillbirth rate in piglets is inadequate. Therefore, this study was conducted to determine important risk factors for an extremely high stillbirth rate in a commercial pig farm in Vietnam. Materials and Methods: This study included 628 piglets and 45 Landrace × Yorkshire sows. Data including parity number, gestation length (GL), litter size (LS), piglet's gender, stillbirth, birth order, birth interval (BI), cumulative farrowing duration (CFD), birth weight (BW), crown-rump length (CRL), body mass index, and ponderal index (PI) were collected. To deal with hierarchical data where several piglets might be born from a sow, Generalized Linear Mixed Models (GLMMs) were used to examine the association between stillbirth and investigated risk factors. Results: The stillbirth rate was 14.3%, and the incidence of stillbirth at the litter level was 68.9%. The final multivariate GLMM selected eight factors, including CFD, BI, CRL, BW, PI, GL, LS, and parity, as significant risk factors for stillbirth in the piglet.

Materials and Methods: This study included 628 piglets and 45 Landrace × Yorkshire sows. Data including parity number, gestation length (GL), litter size (LS), piglet’s gender, stillbirth, birth order, birth interval (BI), cumulative farrowing duration (CFD), birth weight (BW), crown-rump length (CRL), body mass index, and ponderal index (PI) were collected. To deal with hierarchical data where several piglets might be born from a sow, Generalized Linear Mixed Models (GLMMs) were used to examine the association between stillbirth and investigated risk factors. Results: The stillbirth rate was 14.3%, and the incidence of stillbirth at the litter level was 68.9%. The final multivariate GLMM selected eight factors, including CFD, BI, CRL, BW, PI, GL, LS, and parity, as significant risk factors for stillbirth in the piglet. CFD &gt;90 min, BI &gt; 30 min, CRL 13, and parity 5–8 were associated with increased stillbirth. The final model explained 50.1% of the variation of stillbirth, in which fixed factors explained 43.6% of the variation. Conclusion: The present study indicated that the stillbirth rate in the investigated pig farm was very high, and several factors simultaneously contributed to the situation. Selection for optimal size and shape of piglets, careful supervision of parturition, and replacement of old sows should be some of the practical approaches to reduce the stillbirth rate. J. Adv. Vet.
