Abstract
Leptospirosis is a serious zoonotic disease causes by Leptospira spp. infection, and Thailand is an endemic area for both humans and animals. Infected animal such as cattle, sheep and goats can mostly be asymptomatic but can experience foetal abortions and stillbirths. Infected animals play a role in spreading the bacteria via urine. This study determined leptospirosis in meat goats of Southern Thailand by a molecular detection method. In total, 323 serum samples were collected from meat goats from representative provinces of Southern Thailand, namely Songkhla (179) and Yala (144), from April to June 2022 by the veterinarian of the Regional Livestock Health Unit 9, Songkhla, Thailand. Antibodies from previous infections were screened using the lepto-latex test. Polymerase chain reaction (PCR) targeted the LipL32 gene, and overall positivity was 76.47% (247/322). There was no statistically significant difference between the results from Songkhla (76.54%) and Yala (76.39%). The LipL32 PCR indicated an overall positivity of 9.29% (30/323), positive samples from Yala (18.75%) were significantly more abundant than those from Songkhla (1.68%) (P<0.00001). This study indicates a low active infection with a high previous infection (seroprevalence) of leptospirosis in meat goats, suggesting the circulation of leptospirosis of meat goats in Southern Thailand. DNA sequencing for analysing the serovars distribution among goat is needed. Disease prevention via vaccination based on serovar in Thailand be considered. Moreover, molecular detection of leptospirosis be applied for surveillance at herd level, and farmers and persons in contact with goats should be aware of Leptospira infections.

Abstract
This review was written to emphasize the clinical importance of the trace elements selenium (Se), copper (Cu), cobalt (Co), iodine (I), iron (Fe), zinc (Zn) and manganese (Mn) in farm animals especially camels, cattle, sheep and goats. The deficiency of Se can have major economic effects by lowering fertility, causing placental retentions, and increasing the risk of metritis and mastitis. Se contributes to the development and function of cytotoxic T cells, natural killer cells and helper T cells in the immune system. The Cu is a co-factor in numerous enzymatic processes that include the synthesis of collagen, maturation of red blood cells, the production of energy, the formation of hormones, and the defense against oxidative damage. When excessive amounts are present, it can be extremely risky. The Co is required for the formation of vitamin B12 by rumen microorganisms; thus, Vitamin B12 insufficiency is the result of Co deficiency. Co deficiency results in anemia that is both normochromic and normocytic, as well as anorexia, loss of body condition, and wasting of muscles. Decreased weight gain, photosensitivity and lacrimation, scaly ears, wool discoloration, cardiovascular diseases, and cerebrocortical necrosis are all indications of Co deficiency. Iodine deficiency is a common cause of disorders ranging from goiter to metabolic and neurological disorders. These disorders may occur from the embryonic stage until adolescence. Iodine deficiency in ruminants causes goiter, particularly in young animals, and consequently lowers the chance that lambs and newborns will survive. Animals may develop an iodine shortage for two reasons: low iodine intake and goiterogenic substance consumption. Fe is essential for several catalytic events, oxidative metabolism, oxygen transport, and cell proliferation. It functions as a cofactor for several proteins and enzymes required for the metabolism of oxygen and energy as well as for many of other vital functions. Zn is regarded to be necessary for the functioning of many proteins, important enzymes, and transcription factors because they bind to Zn. Mn plays a crucial role in the production and activation of several enzymes. It is involved in the metabolism of glucose and lipids, and it accelerates the synthesis of proteins, vitamin C, and vitamin B. Ultimately, even if trace elements are only needed in little quantities, their lack can result in many diseases and disorders in livestock, leading to significant financial losses Therefore, balanced diets are required to prevent such affections in camels, cattle, sheep and goats.

Abstract
This study aimed to evaluate the impact of different inclusion levels of a fermented mixture of palm kernel cake (PKC) and cassava byproduct (CB), combined with turmeric in feed, on broiler carcass performance, including body weight, carcass percentage, abdominal fat percentage, meat fat content, and blood cholesterol levels. The research was designed using a Completely Randomized Design with a 4×2 factorial pattern, where the first factor was the level of fermented product usage in feed (0, 10, 20, and 30%), and the second factor was the inclusion of turmeric (without and with 2.5% turmeric of total feed). The results showed an interaction effect between the level of fermented product usage and the inclusion of turmeric on blood cholesterol levels, with the combination of 30% fermented product usage and turmeric resulting in the lowest cholesterol level (110.5mg/dL). The level of fermented product usage affected body weight, abdominal fat percentage, and blood cholesterol levels but did not affect carcass percentage or meat fat content. On the other hand, including turmeric in feed reduced blood cholesterol levels and tended to increase carcass percentage. Based on these findings, it is suggested that the dosage of turmeric be increased in the feed so that the combined effect of mixed fermentation products of PKC and CB with turmeric can significantly influence all investigated variables.

Abstract
Black Soldier Fly larvae (BSFL) are larvae of the Hermetia illucens beetle, which can serve as a protein source in poultry feed; however, their impact on production and quality remains inconsistent. Therefore, this study aimed to assess the utilization of BSFL as a protein source for laying hens in terms of production performance and egg quality. Study selection followed the PRISMA protocol. This meta-analysis retrieved 44 studies from 17 articles, utilizing Hedges’d as the effect size metric. The results indicated that the production performance of laying hens fed diets containing BSFL did not differ significantly from control diets regarding egg weight, egg mass, hen day production, feed conversion ratio (FCR), and feed intake. However, significant differences (P<0.05) were observed in all egg quality parameters except for shell thickness and cholesterol content. The inclusion of BSFL in laying hen diets significantly increased (P<0.05) Haugh Unit (HU), egg yolk color score, and level of lauric, myristic, and palmitic acids. Sub-group analysis of larvae forms revealed that non-defatted BSFL exhibited the best FCR. Meta-regression analysis identified the optimal BSFL inclusion level for laying hens as 12%.

Abstract
The mutations of the growth hormone (GH) gene significantly affect the fertility traits of various cows including service per period and calving interval. Identification of GH gene polymorphism is crucial to preserve the genetic resources of Jawa-Brebes cattle. Thus, we identified the single nucleotide and genetic polymorphisms in Jawa-Brebes cattle based on intron 3 to exon 5 of the GH gene. The amplified products (1,135 bp) of the GH gene from 24 heads of Indonesian cows (Jawa-Brebes, Bali, Madura, and Peranakan Ongole [PO]) were sequenced using the 1st BASE sequencing method. Clustal W and phylogenetic analyses to detect single nucleotide polymorphism and relationship to other breeds were used in the study. A total of 13 variable sites with 10 parsimony and 3 singleton sites were detected in the GH gene within Jawa-Brebes cattle, namely 3 sites in intron 3, 6 sites in intron 4, and 4 sites in exon 5. Three Indels were detected in Jawa-Brebes cattle at the 1,540th (g.1539_1540insT), 1,549th (g.1548_1549insG), and 1,895th (g.1894_1895insC) positions. The genetic distance was 0.000 to 0.013 within Jawa-Brebes cattle. Jawa-Brebes cattle were genetically close to Indonesian local cattle (Bali, Madura, and PO cattle). In addition, Jawa-Brebes cattle had a closer relationship with Bos indicus than Bos taurus. The sequences of intron 3, intron 4, and exon 5 of GH gene were polymorphic. The study provided initial bioinformatics of GH gene sequence that might be used to preserve Jawa-Brebes cattle and as reproduction traits marker-assisted selections in further investigation.Keywords: Growth Hormone, Indonesia, Native cattle, Polymorphism.

Abstract
This study aimed to determine the efficacy of the Aeromonas veronii bv veronii BmCL-03 vaccine to control the MAS disease of African catfish (Clarias gariepinus). The research used an experimental method with a completely randomized design (CRD), five treatments, and three replications. The treatments consisted of T1: intramuscular (i.m) injection; T2: intraperitoneal injection (i.p); T3: oral; T4: immersion; T5: without vaccination (control). Booster vaccination was carried out one week after using the same method, except for oral vaccination, which was given during the first ten days. In the third week, each fish was given 0.1mL of A. veronii bv veronii suspension at a 107 CFU/mL dose for all treatments as part of the challenge test. Antibody titer, survival rate (SR), relative percent survival (RPS), mean time to death (MTD), and growth rate are among the research factors. The data were analyzed using analysis of variance (ANOVA) and Duncan multiple range test (DMRT) at a test level of 5%. The results showed that the A. veronii bv veronii BmCL-03 vaccine was significantly different (P<0.05) and could increase antibody titer, SR, RPS, and weight gain of African catfish but was not significantly different (P>0.05) to fish length and MTD. Vaccination does not hurt the growth of African catfish. The vaccine of A. veronii bv veronii effectively protects African catfish, and the i.m injection treatment is the most effective. The A. veronii bv veronii vaccine has good prospects as a vaccine product that can improve the immune system and protect African catfish.

Abstract
This study examined the effects of Moringa oleifera Lam leaf extract, using ethanol solvent at different doses, supplemented with additional minerals and vitamins, on the development of ovarian follicles in female Mus musculus. Thirty-six five-week-old female Mus musculus having reproduction disorder were used in the current experiment. The experimental design was a completely randomized design, with four different levels of M. oleifera Lam leaf extract (T1=4mg/kg Live weight (LW), T2=8mg/kg LW, T3=12mg/kg LW, and T4 or control=0 mg) fed to the animals. The data were analyzed using one-way ANOVA in SPSS and the histopathological analysis was descriptively conducted. The results indicated that treatments T1, T2, and T3 ensured adequate feed and high daily weight gain in Mus musculus. Histopathological examination of the ovaries revealed that a 4mg/kg LW dose of M. oleifera Lam leaf extract was sufficient to promote ovarian development and normalize the reproductive cycle.

Abstract
This study investigates the motility and viability of Kokok Balenggek chicken (KBC) spermatozoa in various commercial physiological solutions, specifically Ringer’s Lactate (RL), Sodium Chloride 0.9% (NaCl 0.9%), and Phosphate Buffered Saline (PBS), all stored at 4ºC. A total of 15 KBC specimens were utilized in this research. Semen collection occurred bi-weekly at 3-day intervals, followed by a comprehensive evaluation of spermatozoa quality, encompassing volume, pH, color, consistency, mass movement, motility, concentration, and viability. The results indicated that the average volume of KBC semen was 0.35±0.16 mL, characterized by a white color, thick consistency, and a pH of 7.09±0.21. Microscopic evaluation unveiled a spermatozoa mass movement score of 3.0±0.0 (+++), spermatozoa motility of 90±0.0%, live spermatozoa percentage of 95±1.71%, and a spermatozoa concentration ranging from 2419±0.74×106 cells/mL. Moreover, a significant difference (P<0.05) in the longevity of KBC spermatozoa was observed in RL solution compared to 0.9% NaCl solution and PBS. RL diluent exhibited superior performance (P<0.05) over 0.9% NaCl solution and PBS, with the longest motility and viability persisting up to 288 hours (0.71±1.82% and 0.84±2.22%). Conversely, the 0.9% NaCl solution displayed the shortest motility and viability, lasting 72 hours (1±2% and 2±4%), while the PBS solution maintained viability up to 120 hours (0.3±1.3% and 0.5±1.9%). In conclusion, storing KBC semen at 4ºC using RL diluent resulted in superior longevity, motility, and viability of spermatozoa compared to 0.9% NaCl solution and PBS.

Abstract
In this work, single-nucleotide polymorphisms (SNPs) in the II and III exon parts of the interleukin-8 (IL-8) gene and the II exon part of IL-17 (SNP c.126G>A) were studied. The effects of IL-17A gene alleles on the reproductive ability of Holstein cows (n=164, Medeu Commerce LLP) were determined. This study revealed the absence of genetic polymorphisms at the IL-8 gene locus, where carriers of only homozygous AA genotypes for both SNPs were identified. Concerning the IL-17A gene locus (SNP c.126G>A), an excessive occurrence of the heterozygous AG genotype (+15,622 specimens) was observed. Cows successfully inseminated within 45–60 and 61–90 days after calving most often had the IL-17A gene locus with homozygous GG genotypes (50.0 and 25.0%). In this group of animals, 8.06 and 19.5% had the homozygous AA genotype, and 7.77 and 25.55% had the heterozygous AG genotype. On the basis of these results, the authors believe that the G allele positively correlates with high reproductive ability in Holstein cows. The IL-17A polymorphism (SNP c.126G>A) can be used as a DNA marker of reproductive function. In cows of the Holstein breed at Mezhdurechensk AGRO LLP (n=150) and in stud bulls of Holstein and black-and-white breeds at Asyl Tulik JSC (n=37), the prevalence of the fertility haplotype was 4.67% and 5.40%, respectively, and the complex vertebral malformation hereditary anomalies occurred in 7.33% and 8.10%, respectively. The polymerase chain reaction-restriction fragment length polymorphism and real-time polymerase chain reaction methods confirmed the high diagnostic effectiveness during genetic screening. Thus, according to the existing international strategy for eliminating harmful mutations in breeding animals, examining 10–20% of livestock for carriers of genetic defects is recommended.

Abstract
Citronella waste (Cymbopogon nardus L. Rendle) is potentially used as a fiber source in livestock feed but contains a high lignin content. Processing through ammoniation and supplementation with probiotics and minerals is required to enhance digestibility in livestock feed. Saccharomyces cerevisiae and mineral sulfur are essential probiotics and minerals for improving rumen microorganism balance and optimizing fiber-digesting microorganisms. This study aims to examine the effect of S. cerevisiae and mineral sulfur supplementation on an ammoniated Citronella waste (ACW) basal diet to optimize rumen bioprocesses, thereby enhancing intake, nutrient digestibility, milk production, and milk quality in Etawa crossbreed goats. The study employed experimental methods involving PE goats, grouped based on milk production into four groups, each receiving one of four treatments (P0, P1, P2, P3). Testing with ANOVA (Analysis of Variance) and the differences obtained from the analysis of variance for the treatments were followed by the DMRT (Duncan’s Multiple Range Test). The results indicate that supplementing S. cerevisiae and mineral sulfur supplementation on ACW had no significant effect on nutrient intake, yet it significantly improved nutrient digestibility. This combination also exhibited no significant impact on milk production and quality (protein, and lactose) but substantially affected milk fat content. In conclusion, using a combination of 0.5% S. cerevisiae and 0.3% mineral sulfur, along with including Citronella waste in the diet, can enhance the efficiency of nutrient utilization in crossbred Etawa goats.

Abstract
The gradual increase of antibiotic resistance of E. coli has become alarming to public health; moreover, isolates have virulence genes affecting the severity of infections. Sequencing virulence genes and studying their phylogenic relations are effective for infection control. The current study aimed to determine the prevalence of E. coli isolates from horses suffering from respiratory manifestation and their antimicrobial resistance, virulence determinants, biofilm production, and phylogeny of these strains. Polymerase Chain Reaction (PCR) was used to detect virulent genes such as eaeA, Iss, papC, astA, AdrA, iutA, Stx1, and Stx2. Furthermore, isolates were screened for antibiotic-resistance genes such as blaTEM and Sul1. All identified E. coli strains were positive for the following virulence genes: eaeA, Iss, papC, astA, iutA, and AdrA with 100% incidence. Shiga toxin genes (Stx1 and Stx2) were not revealed in all E. coli isolates examined. Furthermore, the examined bacterial isolates harbored the ?-lactamase resistance gene (blaTEM) and sulphonamide resistance gene (Sul1). PCR products were sequenced, and four sets of DNA sequences for E. coli isolates were produced and deposited in GenBank for ast, iss, eae, and papC gene. In the present study, virulent antibiotic-resistant strains of E. coli in equines threaten the public’s health. Phylogenic analysis of these genes exhibits an effective method for disease control.

Abstract
Most cases of mastitis are caused by bacteria that infect the udder through the milk ducts causing inflammation. The objective of this study was to identify the bacteria that cause mastitis in farms that apply different milking management. Mastitis testing using the California Mastitis Test (CMT) was conducted on 132 quarters of milk samples from 33 cows in three farms with different milking management practices. The 3 positive samples from each farm were taken and analyzed for metagenomics in the laboratory. The V1-V9 regions of the 16S ribosomal RNA gene were amplified using primers 27F and 1492R under specific polymerase chain reaction conditions for bacterial identification. DNA concentration was determined using both NanoDrop spectrophotometers and Qubit fluorometer. Library preparations were conducted using Kits from Oxford Nanopore Technology. Primary data were obtained using MinKNOW version 23.04.5. The results of metagenomic analysis of mastitis cow milk samples from farms with different milking management were dominated by bacteria from the Firmicutes and Proteobacteria phylum. Streptococcus agalactiae was the dominant bacteria causing mastitis in Kemiri farm and UPTD BPBPTDK, while Lactococcus lactis was the dominant bacteria causing mastitis in UPT farm. Kemiri farm had the highest diversity of bacteria in milk compared to the other two farms. The same 56 bacterial species were found on all three farms. Different milking management practices on the three farms showed different bacterial diversity and causes of mastitis.

Abstract
The study provides evidence of a high prevalence of zoonotic gastrointestinal parasites in fecal samples from beef and dairy cattle in a central area of northeastern Thailand. This finding is particularly significant given the lack of previously reported data on potential zoonotic intestinal parasites in cattle from this region. In total, 78 and 79 fecal samples from beef cattle and dairy cattle were collected directly from fresh stool and then processed using fecal floatation and fecal sedimentation techniques to examine for intestinal protozoa and nemathelminths, respectively. In this study, 71.79% of fecal samples from beef cattle were infected with at least one parasite. In beef cattle, five groups of parasites were strongyles (51.28%), Strongyloides spp. (8.97%), Trichuris spp. (1.28%), Moniezia spp. (1.28%) and Eimeria spp. (8.97%). In dairy cattle, 84.81% (67/79) of samples showed positive with infection. Seven species of potentially zoonotic parasites are strongyles (64.56%), Strongyloides spp. (1.27%), Trichuris spp. (2.5%), Cappillaria spp. (2.5%), Toxocara spp. (5.06%), Eimeria spp. (10.13%) and Balantidium spp. (1.27%). This study provides crucial information needed to design effective strategies for the prevention and control of the parasitic zoonoses.

Abstract
As an integral and important part of the livestock industry, interest in dairy goat farming has been growing steadily in recent years. At the same time, the milk productivity of goats is largely determined by the balance and completeness of the diet. Our study aimed to determine the effect of adding chlorella suspension in combination with a probiotic to the diet of Saanen goats on the quality characteristics of the milk obtained during the milking process. The material base for the experimental study was the goat breeding farm of the Lukoz agricultural holding in the Sernursky district of the Republic of Mari El, where, according to the principle of analogs, dairy goats at the stage of the second lactation were divided into 3 groups of 20 heads each. The control group was kept on a normal diet. Goats belonging to the experimental groups received chlorella suspension daily with water at the rate of 40ml per animal. The second experimental group additionally received the probiotic Bacillus subtilis at 10g per animal. Every 10 days, milk productivity was analyzed through control milking, and blood and milk samples were taken for laboratory analysis. The study showed a significant increase in the number of erythrocytes and hemoglobin levels in the blood of the experimental groups of animals. In addition, an increase in the concentration of glucose, total protein, albumin, and globulins in the blood serum was observed, which indicates the activation of metabolic processes, including carbohydrate metabolism. Adding chlorella suspension to animals’ diets benefits the functioning of the body’s immune system. The phagocytic activity of neutrophils in the body indicates the animal’s immune status. The use of chlorella suspension in goat diets helps not only strengthen the immune system but also increases the milk yield of animals. With these supplements, goats produce more milk, and also the total protein, casein, fat, and mineral content of the milk are increased. This is an important factor for dairy producers, as it improves the quality and value of the resulting product.

Abstract
The objective of this study was to assess the effects of saponins derived from Chenopodium quinoa by-products on methane (CH4) production in a ruminal fermentation system under in vitro conditions. Additionally, the study included the analysis of short-chain fatty acids (SCFAs) and true dry matter digestibility (TDMD). The saponin extracts obtained from three quinoa varieties were Altiplano (AS), Quillahuaman (QS), and Salcedo (SS), and were tested at six different doses (0, 0.2, 0.4, 0.6, 0.8, and 1.0mg/mL) each. Rumen fluid was obtained from two fistulated Junín breed sheep, with alfalfa hay (AH) and a 1:1 mixture of maize and bran (MB) was used as basal substrates. The data were processed in a completely randomized design and replicated three times. The CH4 per dry matter (mL/g DM), after 24h of incubation significantly decreased, acetate molar concentration decreased (p<0.05) with AS (3.6%) and QS (6.4%), propionate values increased (P<0.05) to 14.4% (AS), 15.7% (QS), and 15.5% (SS), the acetate-to-propionate ratio decreased (P<0.05) across all saponins treatments compared to the control and irrespective the substrates. The CH4 to TDMD ratio decreased (P<0.05) with all saponins. Methane inhibition (mL CH4/100mgTDMD) was higher by up 25.7% in the presence of AS, followed by QS at 18.7% and SS at 14.6%. The results indicate that saponins extracted from quinoa possess significant potential as feed additives for ruminants. Their application could contribute to the reduction of methane production, which would be advantageous for both livestock efficiency and environmental sustainability.

Abstract
Stem cell therapy is one of the most promising fields of biomedical research, as enthusiasm for its applications and effectiveness have been proven in different therapeutic approaches. Therefore, we aimed to appraise the therapeutic role of adipose tissue-derived mesenchymal stem cells (AT-MSCs) in mitigating cyclophosphamide (CTX)-induced infertility in a rat model. The study included three experimental groups: control, CTX, and stem cell treatment groups. Testes were collected for histopathological analysis and gene expression assessment of protamine, prohibitin, and StAR genes. The results showed that cyclophosphamide impaired spermatogenesis and caused testicular damage. However, the transplantation of AT-MSCs facilitated the restoration of the seminiferous epithelium and enhanced the regeneration of spermatogenesis. The expression of protamine, prohibitin, and StAR genes was upregulated in the AT-MSCs group compared to the CTX group. This study provides further evidence for the relationship between the expression of protamine and prohibitin genes and male infertility. In conclusion, AT-MSCs were able to recover the spermatogenesis process and regenerate the damaged testicular elements in cyclophosphamide-treated rats.
