Dietary fiber was used for reduce feed cost in local animal production. However, other advantages effects were interesting to study. Therefore, the objective of this research was to investigated effect of fiber source diet on performance, carcass quality, oxidative stress and intestinal morphology in Thai native chicken. A total of 300 one-day-old (mixed sex) crossbred native chicks (Pradu Hang dum) were randomly assigned to 5 treatments in completely randomized design (CRD). Each treatment had 10 replicates with the crossbred native chickens 6 bird/replicates (1 to 12 weeks of age) were given different levels of banana stem and Napier grass. Treatment diets received as follows a basal diet; 100%, no supplement or control group (CON), basal diet; 95%, 90% supplemented with the banana stem at 50 g/kg, 100 g/kg (BS 5%, BS 10%) of diet, respectively, and basal diet; 95%, 90% supplemented with the Napier grass at 50 g/kg, 100 g/kg (NG 5%, NG 10%) of diet, respectively. The results of the study showed that the use of fiber source: banana stem at 50 g/kg and Napier grass 100 g/kg of the diet improved growth performance. The result showed benefits to increase body weight, improve feed conversion ratio (FCR) and feed cost per gain (FCG), improve to gut health by increase villus height (VH), Villus width (VW) in duodenal and jejunal small intestine morphology, reduced malondialdehyde (MDA) levels in serum (p < 0.001). In addition, significantly higher thigh meat percentage (p < 0.05) without effecting visceral weight and overall carcass percentage.
膳食纤维在地方动物生产中用于降低饲料成本。然而,其他的优势效应也值得研究。因此,本试验旨在研究纤维源饲粮对泰国土鸡生产性能、胴体品质、氧化应激和肠道形态的影响。试验采用完全随机设计(CRD),将300只1日龄(雌雄杂交种)杂交土鸡随机分为5个处理。每个处理10个重复,杂交土鸡6只/重复(1 ~ 12周龄),饲喂不同水平的香蕉茎和纳匹尔草。试验饲粮为基础饲粮;100%,不添加或对照组(CON),基础日粮;95%、90%分别添加50 g/kg、100 g/kg (BS 5%、BS 10%)饲粮和基础饲粮;95%、90%分别在饲粮中添加50 g/kg、100 g/kg (NG 5%、NG 10%)的纳匹尔草。研究结果表明,纤维源:香蕉茎50 g/kg和纳匹尔草100 g/kg的饲粮可提高生长性能。结果表明:增加体重,提高饲料系数(FCR)和每增重饲料成本(FCG),提高十二指肠和空肠小肠绒毛高度(VH)、绒毛宽度(VW),降低血清丙二醛(MDA)水平,有利于改善肠道健康(p < 0.001)。此外,腿肉率显著提高(p < 0.05),但对内脏重和总胴体率没有影响。

Salmonella Enteritidis is one of the most common serovars associated with gastroenteritis in humans. Fluoroquinolone resistance in non-typhoidal Salmonella including S. Enteritidis has increased globally and is considered as a threat to public health. In this study, we aimed to investigate the occurrence of ciprofloxacin resistance and plasmid-mediated quinolone resistance (PMQR) genes, and examine virulence gene profiles of 69 S. Enteritidis isolates recovered from 46 boot swab and 23 intestinal samples collected from 69 commercial intensive broiler farms in Thailand. Ciprofloxacin susceptibility of these isolates was determined using microbroth dilution method. PCR was used to detect 5 common PMQR genes (qnrA, qnrB, qnrS, aac(6')-Ib-cr and qepA) and 12 important virulence genes (agfA, invA, spaN, prgH, sitC, ssaQ, mgtC, sopB, sifA, tolC, cdtB and spvC). All S. Enteritidis showed reduced susceptibility to ciprofloxacin, with the MIC values of 0.125-0.50 µg/mL. However, these isolates did not carry PMQR genes investigated. The same virulence profile was observed among 69 S. Enteritidis isolates in which 11 virulence genes, except cdtB, were detected. The presence of virulence genes identified in invasive salmonellosis in the S. Enteritidis isolates with reduced susceptibility to ciprofloxacin could be of public health concerns. Our findings underline the need for constant monitoring of ciprofloxacin-resistant S. Enteritidis in poultry production chain to reduce public health risk.
肠炎沙门氏菌是人类肠胃炎最常见的血清型之一。包括肠炎沙门氏菌在内的非伤寒沙门氏菌对氟喹诺酮类药物的耐药性在全球范围内有所增加,并被认为是对公众健康的威胁。在本研究中,我们旨在调查环丙沙星耐药性和质粒介导的喹诺酮类耐药性(PMQR)基因的发生情况,并检测从泰国69个商业密集型肉鸡场采集的46个靴拭子和23个肠道样本中分离的69个肠炎沙门氏菌的毒力基因图谱。用微量roth稀释法测定这些分离株对环丙沙星的敏感性。用PCR方法检测5个常见PMQR基因(qnrA、qnrB、qnrS、aac(6')-Ib-cr和qepA)和12个重要毒力基因(agfA、invA、spaN、prgH、sitC、ssaQ、mgtC、sopB、sifA、tolC、cdtB和spvC)。所有肠炎沙门氏菌对环丙沙星的敏感性均降低,MIC值为0.125-0.50µg/mL。然而,这些分离株没有携带所研究的PMQR基因。在69个肠炎沙门氏菌分离株中观察到相同的毒力谱,其中除cdtB外,共检测到11个毒力基因。在对环丙沙星易感性降低的肠炎沙门氏菌分离株中,在侵袭性沙门氏菌病中鉴定出的毒力基因的存在可能会引起公众健康问题。我们的研究结果强调,需要在家禽生产链中持续监测耐环丙沙星的肠炎沙门氏菌,以降低公共健康风险。

This review article was designed to spotlight on erysipelas infection of poultry regarding the disease history and nomenclature, the bacterium, virulence factors and pathogenicity, susceptibility, infection and transmission, pathology, human infection, laboratory diagnosis, and the prevention and control. Erysipelas is an acute emerging and occupational disease that affects a wide range of birds especially turkeys. The disease is caused by a bacterium, Erysipelothrix rhusiopathiae (E. rhusiopathiae), which is a ubiquitous pathogen in the environment. Infection with E. rhusiopathiae is more common in adults than young birds and usually occur through mechanical skin injuries. Erysipelas in acute stage causes sudden death of infected birds, while some birds may show darkening of the skin or cyanosis in the head region and sharp drop in egg production. In post-mortem lesions, birds with E. rhusiopathiae show septicaemic picture, haemorrhages all over the body, valvular endocarditis, diffuse enlargement of internal organs, enteritis, and arthritis. The disease in human is known as erysipeloid and it mostly affects persons in direct contact with infected birds or contaminated poultry products. Strict biosecurity measures and treatment especially with penicillin derivatives are crucial for erysipelas control in infected birds. Living and inactivated vaccines for turkeys and other species of birds are used for prophylaxis.
本文从病史和命名、细菌、毒力因子和致病性、易感性、感染和传播、病理学、人类感染、实验室诊断和预防控制等方面对家禽丹毒感染进行了综述。丹毒是一种急性新发的职业病,影响广泛的鸟类,尤其是火鸡。这种疾病是由一种细菌引起的,这种细菌是环境中普遍存在的病原体。与幼鸟相比,感染蛇颈龙线虫在成年鸟中更常见,通常通过机械性皮肤损伤发生。丹毒在急性期会导致受感染的鸟类突然死亡,而一些鸟类可能表现出皮肤变黑或头部发绀,产卵量急剧下降。在死后病变中,患有蛇颈病的鸟类表现为败血症、全身出血、瓣膜性心内膜炎、内脏弥漫性肿大、肠炎和关节炎。这种人类疾病被称为丹毒,主要影响直接接触受感染鸟类或受污染家禽产品的人。严格的生物安全措施和治疗,特别是青霉素衍生物的治疗,对于控制受感染鸟类的丹毒至关重要。火鸡和其他鸟类的活疫苗和灭活疫苗用于预防。

Roundworm nematodes are a significant problem in goat meat farming worldwide. These parasites can cause production losses, reduce feed efficiency and compromise animal health and welfare. Macrocyclic lactones (MLs) are common anthelmintic drugs to treat roundworm nematode infection in livestock. The objective of study was to detect roundworm resistance to MLs in meat goats in Northeast Thailand. One hundred and nineteen goats from 6 herds were studied from June to December 2022. Each herd was randomly allocated to control (n=21), epinomectin (n=34), ivermectin (n=40) and moxidectin (n=24) groups. Anthelmintic resistance (AR) was assessed based on the Fecal Egg Count Reduction Test (FECRT) and larva culture at pre-treatment (D0) and 14 days post-treatment (D14). Prevalence of Strongyle nematodes and Trichuris spp. infection was 100% (6/6 herd), and 66.7% (4/6 herd), respectively. The number of Strongyle eggs was significantly reduced in the eprinomectin group (p < 0.01). In contrast, the ivermectin group was significantly increased (p < 0.01). The prevalence of ML resistance of Strongyle nematodes and Trichuris spp. was 83.3% (5/6 herd) and 25.0% (1/4 herd), respectively. The dominant larva was Haemonchus contortus at pre- and post-treatment in every herd. This study demonstrated the presence of ML resistant Strongyle nematodes as H. contortus and Trichuris spp. in this area. To reduce ML resistance it can be useful to use drugs in combination or rotate MLs with other classes of anthelmintics or in targeted treatment programs and integrated parasite management strategies. Consequently, the efficacy of anthelmintic drugs in small ruminants needs to be monitored and surveilled in this area.
圆线虫是世界范围内山羊肉养殖中的一个重要问题。这些寄生虫会造成生产损失,降低饲料效率,损害动物健康和福利。大环内酯(MLs)是治疗家畜蛔虫线虫感染的常用驱虫药。本研究的目的是检测泰国东北部肉山羊对MLs的蛔虫抗性。从2022年6月到12月,对来自6个畜群的119只山羊进行了研究。每个牛群被随机分配到对照组(n=21)、伊维菌素组(n=34)、莫西丁组(n=24)。在处理前(D0)和处理后14天(D14),根据粪便蛋数减少试验(FECRT)和幼虫培养来评估抗药性(AR)。Strongyle线虫和Tricuris spp.感染率分别为100%(6/6群体)和66.7%(4/6群体)。依普罗霉素组的Strongyle卵数显著减少(p<0.01)。相反,伊维菌素组显著增加(p<0.01)。Strongyle线虫和Tricuris spp.的ML抗性发生率分别为83.3%(5/6群)和25.0%(1/4群)。在处理前后,每个群体的优势幼虫为扭曲血蜱。这项研究证明了该地区存在抗ML的Strongyle线虫,如扭曲线虫和鞭虫。为了降低ML耐药性,将ML与其他种类的驱虫药组合或轮换使用,或在靶向治疗计划和综合寄生虫管理策略中使用药物可能是有用的。因此,需要在这一领域监测和监测驱虫药物对小型反刍动物的疗效。

Rapid influenza diagnostic tests (RIDTs) could considerably assist in clinical management resolving outbreaks of diseases in humans and animals. The RIDT for animals is rarely available and considerably expensive, especially in Thailand. In this study, therefore, the objective of this study was to determine the capacity of a commercial human RIDT “QuickNavi™Flu2”, an RIDT for influenza viruses A and B, to detect influenza viruses A antigen including 2 inactivated swine influenza viruses: H1N1 and H3N2, canine parainfluenza virus, and feline calicivirus. In addition, the efficacy of QuickNavi™Flu2 was compared with the real-time polymerase chain reaction assay (real-time rt-PCR). Both of SIV were used as stock solutions, and were serially diluted 6 concentrations before testing. The stock and diluted solutions of both SIV, specimens of canine parainfluenza virus, feline calicivirus and 96 unknown samples were tested by QuickNavi™Flu2 according to the guideline. Then all of samples were repeated testing with real-time rt-PCR assay. Results showed that Quick Navi-Flu could not give positive results for dilutions lower than 1:10 and 1:100, respectively. The sensitivity and specificity values of QuickNavi™Flu2 test in comparison to real-time rt-PCR assay for influenza A virus were 36.1% and 100%, respectively. In conclusion, a human RIDT can detect swine influenza H1N1 and H3N2 in high viral concentration, and appeared to be a useful tool for screening in animals when the viral load is sufficient.
快速流感诊断试验(RIDTs)可在很大程度上协助临床管理,解决人类和动物中的疾病暴发。动物的RIDT很少有,而且相当昂贵,特别是在泰国。因此,在本研究中,本研究的目的是确定商用人流感病毒“QuickNavi™Flu2”和流感病毒a和流感病毒B的RIDT检测流感病毒a抗原的能力,包括2种灭活的猪流感病毒:H1N1和H3N2、犬副流感病毒和猫杯状病毒。此外,将QuickNavi™Flu2的疗效与实时聚合酶链反应(real-time rt-PCR)进行比较。两种SIV均作为原液,在检测前进行连续稀释。根据指南使用QuickNavi™Flu2对SIV、犬副流感病毒、猫杯状病毒标本和96个未知样本的原液和稀释液进行检测。然后用实时rt-PCR法重复检测所有样品。结果表明,当稀释度分别低于1:10和1:100时,Quick Navi-Flu不能给出阳性结果。与实时rt-PCR相比,QuickNavi™Flu2检测甲型流感病毒的敏感性和特异性分别为36.1%和100%。综上所述,人的RIDT可以检测出高病毒浓度的猪流感H1N1和H3N2,当病毒载量足够大时,它似乎是一种有用的动物筛选工具。

Cats with azotemia and uremia are increasingly treated with integrative and alternative treatments, including herbal medicines. KID-T (Sin-gi-hwan) is a supplement made of 100% natural herbs and contains 18 herbs, and the components were designed to improve renal function in. Feline renal patients with azotemia and uremia were recruited, and the efficacy of KID-T was examined. Four cats were treated with oral KID-T twice a day for 3 months, and blood biochemical profiles were examined to monitor the toxicity and efficacy of KID-T each month. KID-T was well-tolerated and relatively safe during the treatment period. After 3 months, ammonia, blood urea nitrogen, and creatinine levels were relatively close to the normal reference range in all cats, and the urine protein–creatinine ratio decreased.

Environment represents as a reservoir for emerging and disseminating of antibiotic resistance genes. Slaughterhouse waste is one of the important sources of antibiotic resistance genes (ARGs) even after treatment processes. This study was conducted to evaluate role of farm animal slaughterhouse in dissemination of antibiotics resistance in Al-Dewanyiah, Iraq. A total of eighty samples were collected from the central farm animal slaughterhouse. The detection was based on three mobile genetic elements and nine antibiotic resistance genes. The results showed that tetO & tetK are common resistance genes in the tested samples with great relative abundance 60%. While, MGE transposon (Tn3) was detected in 80% of the tested samples. Gene encoding resistance to quinolone, methicillin, aminoglycoside and β-lactamases were also detected in the tested samples. Presence of three class of integrons as a mobile genetic were tested and the results of type 1 recorded high abundance (P>0.05) as a compare with type 2 and type 3 integrons. Furthermore, concentrations of ARGs and MGEs per gram of sample were tested using qPCR. The genes encoding for tetracycline resistance and transposon (Tn3) were found in higher concentration (P>0.05) (copy number) per gram of slaughterhouse sediments comparing with the selected genes. Quantification of ARGs and MGEs in the slaughterhouse wastes indicates that those wastes represent as a hotspot for dissemination of antibiotic resistance to the environment. Low darning and no treatment for slaughterhouse wastes might increase abundance of ARGs and resistant bacteria in the natural environment.
环境代表着抗生素耐药性基因的出现和传播。屠宰场废弃物是抗生素抗性基因(ARGs)的重要来源之一,即使在处理过程之后也是如此。本研究旨在评估农场动物屠宰场在伊拉克Dewanyiah抗生素耐药性传播中的作用。共从中央农场动物屠宰场采集了80个样本。该检测基于三个可移动遗传元件和九个抗生素抗性基因。结果表明,tetO和tetK是供试样品中常见的抗性基因,相对丰度高达60%。而在80%的测试样品中检测到MGE转座子(Tn3)。检测样本中还检测到编码对喹诺酮、甲氧西林、氨基糖苷类和β-内酰胺酶耐药性的基因。测试了三类整合子作为可移动基因的存在,与2型和3型整合子相比,1型的结果记录了高丰度(P>0.05)。此外,使用qPCR检测每克样品的ARGs和MGE的浓度。与所选基因相比,编码四环素抗性和转座子(Tn3)的基因在每克屠宰场沉积物中的浓度更高(P>0.05)(拷贝数)。屠宰场废物中ARGs和MGE的量化表明,这些废物是向环境传播抗生素耐药性的热点。屠宰场废物的低织补和不处理可能会增加自然环境中ARGs和抗性细菌的丰度。

The study aimed to elucidate serum and testicular oxidative stress changes induced by bisphenol A (BPA) and their amelioration by Azanza garckeana (AG) pulp extract and melatonin. Adult New Zealand White rabbit bucks (n = 42), with average live weight of 1.2 ± 0.03 kg and aged 10-18 months were fed ad libitum on a commercial diet. They were randomly divided into seven groups of six (6) bucks each. Group A was administered distilled water (1.5 mL); group B, BPA (100 mg/kg); group C, AG (500 mg/kg); group D, melatonin (1.0 mg/kg); group E was pre-dosed for six weeks with BPA (100 mg/kg), then AG (500 mg/kg) for another six weeks; group F was pre-dosed for six weeks with BPA (100 mg/kg ), then melatonin (1.0 mg/kg) for another six weeks; and group G was pre-dosed for six weeks with BPA (100 mg/kg), then AG (500 mg/kg) and melatonin(1.0 mg/kg) for another six weeks. There was a significant increase (p < 0.05) in the activities of both serum and testicular superoxide dismutase and catalase, concentrations of and reduced glutathione concentration as well as a decrease in MDA concentration in treatment groups. Percentage dead sperm, spermatozoa abnormalities such as detached sperm heads, free, coiled and bent tails in the groups exposed to BPA increased significantly (p < 0.05) compared to controls. It is concluded that BPA-induced oxidative stress. The administration of AG only ameliorated this negative effects better than melatonin. However, optimum results was seen when both substances were administered synergistically.
本研究旨在阐明双酚A(BPA)诱导的血清和睾丸氧化应激的变化,以及阿扎尔(AG)果肉提取物和褪黑素对其的改善作用。成年新西兰大白兔公鹿(n=42),平均活重1.2±0.03 kg,年龄10-18个月,在商业日粮中随意喂养。他们被随机分为七组,每组六(6)美元。A组给予蒸馏水(1.5mL);B组BPA(100mg/kg);C组:AG(500mg/kg);D组褪黑素(1.0mg/kg);E组用BPA(100mg/kg)预给药六周,然后用AG(500mg/kg)再给药6周;F组预给药BPA(100mg/kg)6周,然后再给药褪黑素(1.0mg/kg)6周;G组用BPA(100mg/kg)、AG(500mg/kg)和褪黑素(1.0mg/kg)预给药6周。治疗组血清和睾丸超氧化物歧化酶和过氧化氢酶活性、谷胱甘肽浓度和还原型谷胱甘肽浓度均显著升高(p<0.05),MDA浓度降低。与对照组相比,暴露于BPA组的死亡精子百分比、精子异常(如精子头脱落、游离、卷曲和弯曲的尾部)显著增加(p<0.05)。结论是BPA引起氧化应激。AG的给药只是比褪黑素更好地改善了这种负面影响。然而,当两种物质协同给药时,可以看到最佳结果。

The development of cattle industry in Iraq and its neighboring countries may be hampered by Theileria annulata (T. annulata) infection. In the present work, the cytochrome b gene (cyt-b) sequences were used to infer the phylogenetic relationships of T. annulata. Fifty blood samples collected randomly from 10 farms of Iraqi local breed cattle in Al-Diwaniyah province were analyzed for piroplasm using microscopic and molecular techniques. Microscopic examination revealed that 37 (74%) of the 50 blood samples examined were infected. In addition, the PCR test showed that 23 (62.2%) of the 37 blood samples (which tested positive (microscopically) were positive. The analysis of the cyt-b 1092 bp gene of T. annulata reported the presence of six genetically related clones. These six clones have been deposited in GenBank as [ON706262, ON706263, ON706264, ON706265, ON706266, and ON706267], and when compared to the T. annulata cyt-b gene (XM949625) from the GenBank database, a unique polymorphism at sixteen sites was discovered. Furthermore, the alignment of our amino acid sequences with the reference sequence reveals thirteen non-synonymous mutations in codons 11, 22, 33, 63, 103, 128, 130, 129, 172,178, and 190, and three silent mutations in codons 124, 128, and 275. Moreover, phylogenetically, our study clones were related to Iraqi, Indian, and Turkish clones. In conclusion, depending on the phylogenetic analysis the current study identified six T. annulata parasite isolates in Iraqi local breed cattle that were genetically related to the Indian, Iraqi, and Turkish clones.
环状泰勒菌(T.annularata)感染可能会阻碍伊拉克及其邻国畜牧业的发展。本工作利用细胞色素b基因(cyt-b)序列推断环纹T.annulata的系统发育关系。使用显微镜和分子技术对从Al-Diwaniyah省10个伊拉克当地品种牛农场随机采集的50份血液样本进行了梨形虫分析。显微镜检查显示,在检查的50份血液样本中,有37份(74%)被感染。此外,PCR检测显示,37份血液样本(显微镜下检测呈阳性)中有23份(62.2%)呈阳性。对环纹T.annulata的cyt-b1092bp基因的分析报告了六个遗传相关克隆的存在。这六个克隆已作为[ON706262、ON706263、ON706264、ON706265、ON706266和ON706267]存放在GenBank中,当与GenBank数据库中的环纹T.cyt-b基因(XM949625)相比时,在16个位点发现了独特的多态性。此外,我们的氨基酸序列与参考序列的比对揭示了密码子11、22、33、63、103、128、130、129、172178和190中的13个非同义突变,以及密码子124、128和275中的3个沉默突变。此外,在系统发育方面,我们的研究克隆与伊拉克、印度和土耳其的克隆有关。总之,根据系统发育分析,目前的研究在伊拉克当地品种的牛中鉴定了六个环纹T.annulata寄生虫分离株,这些分离株在基因上与印度、伊拉克和土耳其的克隆株有关。

This study aimed to determine the effects of threonine (Thr) and crude protein (CP) on the apparent nutrients, amino acid digestibility, and nitrogen balance of local Muscovy ducks at 8 and 10 weeks of age. The study was a 3x2 factorial design for two phases with three levels of CP (17, 18, and 19% CP) and two levels of Thr (0.7 and 0.8% Thr) for the first phase while three levels of CP (15, 16, and 17% CP) and two levels of Thr (0.5 and 0.6% Thr) for the second phase. The birds were fed and given water ad libitum for the entire experiment. The results showed that CP and Thr increased apparent nutrient digestibility, especially for DM digestibility (P < 0.05). Besides, Thr addition also increased OM, and NDF digestibility (P <0.05). In addition, nitrogen balance was better in high-dose Thr and CP diets (p<0.05). For amino acids, when increased Thr and CP levels, it increased the digestibility of Isoleucine, Threonine, and Valine (P < 0.05) while Thr levels increased Methionine, Phenylalanine, Serine, Tyrosine, and CP levels increased Isoleucine, Leucine, Lysine, Threonine, Valine, Alanine, Glutamic, Proline digestibility (P < 0.05). However, this study could not record any interactions between Thr and CP in the diet throughout the experiment (P > 0.05). It can be concluded that supplementation with 0.8% Thr and 19% CP for 5-8 weeks of age and 0.6% Thr and 17% CP for 8-10 weeks of age in the local Muscovy duck diet increased the digestibility of apparent nutrients and amino acids and balanced the nitrogen substance in the duck’s body.
本试验旨在研究苏氨酸(Thr)和粗蛋白质(CP)对8和10周龄地方麻鸭表观营养物质、氨基酸消化率和氮平衡的影响。该研究采用3x2因子设计,分为两个阶段,第一阶段为3个水平的CP (17,18,19 % CP)和2个水平的Thr(0.7和0.8% Thr),第二阶段为3个水平的CP (15,16,17 % CP)和2个水平的Thr(0.5和0.6% Thr)。在整个实验过程中,这些鸟被随意喂食和饮水。结果表明,粗蛋白质和苏氨酸提高了营养物质表观消化率,尤其是DM消化率(P < 0.05)。此外,添加Thr还提高了OM和NDF的消化率(p0.05)。综上所述,5-8周龄饲粮中添加0.8%苏氨酸和19%粗蛋白质,8-10周龄饲粮中添加0.6%苏氨酸和17%粗蛋白质可提高鸭体内表观营养物质和氨基酸的消化率,平衡鸭体内氮物质。
