Embryonic thermal manipulation was known as an effective protocol for improving post-hatch growth performance and thermotolerance acquisition among avian species. Previously, we evaluated the impact of embryonic thermal manipulation of Japanese quail on embryonic development, hatchability, and post-hatch performance. We conducted the current study to furtherly elucidate the effects of thermal manipulations of Japanese quail embryos on internal organ weights, carcass traits, and meat quality parameters at post-hatch day 35. Quail eggs of control group were incubated at 37.7 °C and relative humidity (RH) 55%. Three thermally manipulated groups of quail eggs were incubated intermittently at 41°C and 65% RH intermittently (3 hours/day): the early embryonic group (TM1) was thermally challenged at embryonic day (ED6) to ED8, the late embryonic group (TM2) was thermally challenged at ED12-14, and early/late embryonic group (TM3) was thermally challenged in both time windows. Quail meat quality parameters, carcass traits, and internal organ weights were evaluated at post-hatch day 35. The results revealed that early embryonic thermal manipulation (TM1 group) is an effective protocol for decreasing fat pad accumulation. The pH value of breast meat in all TM treatments revealed significant (P < 0.05) decreases by 5% in comparison with that of control without any negative effects on breast meat composition or sensory criteria. Early embryonic thermal manipulation would be recommended as an enhanced protocol that can be used to reach the favored lucrative effects of the thermal treatment in meat-type quail.
胚胎热操作被认为是提高禽类孵化后生长性能和耐热性获得的有效方案。此前,我们评估了日本鹌鹑胚胎热处理对胚胎发育、孵化能力和孵化后表现的影响。我们进行了目前的研究,以进一步阐明日本鹌鹑胚胎热处理对孵化后第35天内脏重量、胴体性状和肉质参数的影响。对照组鹌鹑蛋在37.7°C、相对湿度(RH)55%的条件下孵育。三组热操作鹌鹑蛋在41°C和65%RH下间歇孵育(3小时/天):早期胚胎组(TM1)在胚胎期(ED6)至ED8受到热攻击,晚期胚胎组(TML2)在ED12-14受到热攻击;早期/晚期胚胎组在两个时间窗口受到热攻击。在孵化后第35天评估鹌鹑的肉质参数、胴体性状和内脏重量。结果表明,早期胚胎热操作(TM1组)是减少脂肪垫堆积的有效方案。与对照组相比,所有TM处理的胸肉pH值显著降低了5%(P<0.05),对胸肉成分或感官标准没有任何负面影响。建议将早期胚胎热处理作为一种增强方案,用于达到肉型鹌鹑热处理的有利利润效果。

The aim of this study was to investigate the influences of sex and age on haematological values in the Posavje Horse breed. A total of 163 healthy Posavje horses (30 foals, 94 mares and 39 stallions) were used in this study; their complete blood counts and a leucogram were obtained with a haematological analyser. The horses were classified into five groups: foals (1 to 6 months, n = 30), 3 to 6 years (n = 8 stallions/21 mares), 7 to 9 years (n = 9 stallions/22 mares), 10 to 13 years (n = 8 stallions/20 mares), 14 to 15 years (n = 6 stallions/10 mares) and 16 and over (n = 8 stallions/21 mares). The results obtained show an influence of sex on haematological parameters, with red blood cell count (RBC), haematocrit (HCT) and haemoglobin concentration (HGB) being higher in stallions (P < 0.001) and white blood cell count (WBC) being higher in mares. Differences between the age groups of the Posavje horses examined indicate a decrease in RBC and HGB with a compensatory increase in mean corpuscular volume and mean corpuscular haemoglobin, a decrease in WBC and platelet counts (PLT) and proportion of lymphocytes, and an increase of neutrophil to lymphocyte ratio (N/L) with age (P < 0.001). Although the Posavje horse is classified as a draft horse breed, its haematological parameters show characteristics common to warm-blooded breeds, with the exception of the N/L ratio. One of the most important findings of this study is a higher neutrophil count in reproductively active breeding stallions. Higher levels of RBC, HGB, HCT and neutrophil count in the Posavje stallions suggest an effect of androgens (testosterone), which may be an effective mechanism to prevent infections, that can affect the survival of the stallions and thus the evolution of the species.KARAKTERIZACIJA HEMATOLOŠKEGA PROFILA PRI POSAVSKEM KONJUIzvleček: Cilj raziskave je bil proučiti vpliv spola in starosti na hematološke parametre pri pasmi posavski konj. V raziskavo je bilo vključenih 163 konj posavske pasme (30 žrebet, 94 kobil in 39 žrebcev), pri katerih smo v vzorcih krvi določali hematološke parametre s hematološkim analizatorjem. Diferencialna bela krvna slika in razmerje med nevtrofilci in limfociti (N/L) je bilo določeno na krvnih razmazih. Konje smo razdelili v pet starostnih skupin: žrebeta (od 1 do 6 mesecev, n = 30), 3 do 6 let (n = 8 žrebcev/21 kobil), 7 do 9 let (n = 9 žrebcev/22 kobil), 10 do 13 let (n = 9 žrebcev/20 kobil), 14 do 15 let (n = 6 žrebcev/10 kobil) ter 16 in več let (n = 8 žrebcev/21 kobil). Rezultati naše raziskave kažejo vpliv spola na preiskovane hematološke parametre; pri žrebcih so število rdečih krvnih celic (RBC), hematokrit (HCT) in koncentracija hemoglobina (HGB) značilno višji (P < 0,001), pri kobilah pa je višje število belih krvnih celic (WBC). Med starostnimi skupinami posavskih konj smo ugotovili zmanjšanje RBC in HGB in posledično kompenzacijo s povečanjem povprečnega volumna in hemoglobina eritrocitov, zmanjšanjem števila levkocitov, trombo
本研究的目的是调查性别和年龄对Posavje马品种血液学价值的影响。本研究共使用163匹健康的Posavje马(30匹小马驹、94匹母马和39匹种马);他们的全血细胞计数和白细胞图是用血液分析仪获得的。这些马被分为五组:小马驹(1至6个月,n=30)、3至6岁(n=8种马/21匹母马)、7至9岁(n=9种马/22匹母驴)、10至13岁(n=8种马/20匹马)、14至15岁(n=6种马/10匹母马和16岁及以上(n=8匹马/21匹马)。结果显示性别对血液学参数的影响,种马的红细胞计数(RBC)、红细胞比容(HCT)和血红蛋白浓度(HGB)较高(P<0.001),母马的白细胞计数(WBC)较高。检查的Posavje马年龄组之间的差异表明RBC和HGB减少,平均红细胞体积和平均红细胞血红蛋白代偿性增加,WBC和血小板计数(PLT)以及淋巴细胞比例下降,尽管Posavje马被归类为一个后备马品种,但其血液学参数显示出温血品种常见的特征,N/L比除外。这项研究最重要的发现之一是繁殖活跃的种马中性粒细胞计数较高。Posavje种马中较高水平的RBC、HGB、HCT和中性粒细胞计数表明雄激素(睾酮)的作用,这可能是预防感染的有效机制,会影响种马的生存,从而影响物种的进化。波萨夫斯基马血液学特征:本研究旨在研究性别和年龄对波萨夫斯基马种血液学参数的影响。这项研究包括163匹Posavje品种的马(30匹小马驹、94匹母马和39匹种马),使用血液分析仪在血液样本中测定血液学参数。在血液涂片上测定差异性白细胞计数和中性粒细胞与淋巴细胞的比率(N/L)。马被分为五个年龄组:小马驹(1至6个月,n=30)、3至6岁(n=8匹种马/21匹母马)、7至9岁(n=9匹种马/22匹马)、10至13岁(n=6匹种马/20匹母羊)、14至15岁(n=六匹种马/10匹马)和16岁及以上(n=8匹马/21匹马)。我们的研究结果表明,性别对所调查的血液学参数的影响;种马的红细胞(RBC)、红细胞压积(HCT)和血红蛋白(HGB)的数量显著较高(P<0.001),母马的白细胞(WBC)的数量则显著较高。在Posavje马的年龄组中,观察到红细胞和HGB的减少,因此红细胞的平均体积和血红蛋白的增加,白细胞、血小板(PLT)和淋巴细胞数量的减少,以及中性粒细胞和淋巴细胞之间的比率(N/L)随年龄的增加而增加(P<0.001)。Posavje马是一匹冷血马,研究中发现的血液学特征显示出温血马品种的共同特征,N/L比除外。这项研究最重要的发现之一是活跃繁殖种马中中性粒细胞数量的增加。Posavje种马较高的RBC、HGB、HCT和中性粒细胞计数表明雄激素(睾酮)的作用,这可能是预防感染的有效机制,感染会影响种马的生存,从而影响物种的进化。关键词:本土品种;Posavo马;血液学;年龄性别

The aim of the study was to investigate the effect of a therapeutic renal diet on selected clinical, biochemical, and urinary parameters and on selected parameters of oxidative stress in cats with early stages of chronic kidney disease (CKD). A prospective study of a 3-month duration was conducted to evaluate the effect of renal diet on selected clinical and laboratory parameters in client-owned cats with early stages of CKD. Of a total of 29 enrolled client-owned cats, nineteen (19) cats completed the study, ten receiving renal diet and nine receiving a diet of the owner's choice. A clinical examination was performed, and blood and urine samples were collected on the day of presentation and at regular check-ups after 3-4, 7-8, and 10-12 weeks. Serum creatinine and symmetric dimethylarginine (SDMA) concentrations and selected parameters of oxidative stress (plasma glutathione peroxidase (GPX) activity and plasma malondialdehyde (MDA) and serum selenium concentrations), were measured and electrophoresis of urinary proteins was performed. At inclusion, a significant positive correlation (p < 0.001) was found between serum selenium concentration and plasma GPX activity (Pearson correlation coefficient 0.83 (95% CI: [0.65 - 0.92]) and a significant negative correlation (p < 0.001) between serum SDMA and urine specific gravity (Pearson correlation coefficient -0.70 (95% CI: [-0.87 - (-0.38)]). At the end of the 3-month feeding trial no significant difference was found in SDMA and creatinine concentrations.

A captive crested porcupine (Hystrix cristata) adult male was imaged due to reduced food intake, anorexia, fever, nasal discharge, changes in fecal quantity and size, and respiratory difficulties. Advanced imaging diagnostic techniques such as computed tomography and magnetic resonance imaging were performed to evaluate the animal. These techniques were very helpful to delineate the dental abscess, as well as the extension of the process to other locations such as the nasal cavity and the tympanic bulla. This is the first description of rhinosinusitis secondary to a dental abscess in a porcupine.

Body temperature is a vital parameter to assess the health of exotic animals. Rectal thermometry is a common way to measure body temperature in rodents, rabbits and ferrets and often considered the gold standard. However, taking a rectal temperature often involves restraint and can lead to stress in these animals. To avoid the stress of rectal temperature measurements, alternative (often less invasive) techniques have been utilized in several species. These methods include tympanic thermometry, axillary thermometry and infrared thermography. It is however important to establish whether these strategies yield comparable readings to  the gold standard. Therefore, a literature review was performed using the MedLine and Google Scholar databases. Base terms referring to rectal temperature and thermometry were combined with species-specific search terms. Relatively few studies were identified about alternatives to rectal temperature measurements in rodents, rabbits and ferrets. In general, it can be noted that only transponder measurements have repeatedly been described to be a valid alternative to rectal temperature measurement. Further research should be conducted.
体温是评估外来动物健康状况的重要参数。直肠测温是啮齿类动物、兔子和雪貂测量体温的常用方法,通常被认为是黄金标准。然而,测量直肠温度通常需要克制,并可能导致这些动物的压力。为了避免直肠温度测量的压力,已经在几个物种中使用了替代(通常是侵入性较小的)技术。这些方法包括鼓室测温法、腋下测温法和红外热像法。然而,重要的是要确定这些策略是否能产生与金标准相当的读数。因此,使用MedLine和Google Scholar数据库进行了文献综述。直肠温度和体温测量的基本术语与特定物种的搜索术语相结合。关于啮齿类动物、兔子和雪貂直肠温度测量的替代方法,研究相对较少。通常,可以注意到,只有应答器测量被反复描述为直肠温度测量的有效替代方案。应当进行进一步的研究。

In humans, estrogens are considered protective factor against atherosclerosis because the risk increases in postmenopausal women. However, it is not clear whether estrogens are the only factor, whether sex chromosomes also have an influence, and whether estrogens play the same role in all mammals. The mouse line C57BL/6J is prone to develop atherosclerotic changes in the largest arteries after prolonged feeding of a high-fat diet containing cholesterol and cholate (Paigen diet). We aimed to examine effect of sex hormones and sex chromosome complement on the development of atherosclerotic plaques using agonadal SF-1 knockout mouse on C57BL/6J background. Gonadally intact and prepubertally gonadectomized WT and agonadal SF-1 knockout C57BL/6J mice of both sexes were exposed to a Paigen diet and a control diet for 20 weeks. We monitored their body weight, food intake, and serum lipid profile. The aortas were examined by the en face method, and the cross sections of the aortic bulbs were stained for lipid content. In all groups of mice, atherosclerotic changes were small and confined to the aortic bulb. The formation of atherosclerotic plaques was sex- and hormone-dependent, as female animals with functioning ovaries developed the most prominent atherosclerotic plaques. Gonadally intact females were also the only group that gained weight comparably on control or atherogenic diet. Diet affected blood biochemistry, but there were almost no significant differences between groups in serum lipid levels. Results indicated main mechanism causing sex-dependent differences in atherosclerosis depends on sex hormones rather than sex chromosomes. Our results also suggest that a mouse model of dietary induced atherosclerosis is of limited use to study the mechanisms of atherosclerosis in humans because the presence of estrogens impairs lipid metabolism and contributes to the formation of atherosclerotic plaques.ŽENSKI SPOLNI HORMONI PREDSTAVLJAJO DEJAVNIK TVEGANJA ZA NASTANEK ATEROSKLEROZNIH SPREMEMB PRI MIŠIH LINIJE C57BL/6J NA ATEROGENI DIETIIzvleček: Pri ženskah se v postmenopavznem obdobju poveča tveganje za razvoj ateroskleroze, zato je splošno sprejeto, da estrogeni hormoni varujejo ožilje pred razvojem tega žilnega obolenja.

在人类中,雌激素被认为是对抗动脉粥样硬化的保护因素,因为绝经后妇女的风险会增加。然而,目前尚不清楚雌激素是否是唯一的因素,性染色体是否也有影响,以及雌激素是否在所有哺乳动物中发挥着相同的作用。C57BL/6J小鼠系在长期喂食含有胆固醇和胆酸盐的高脂饮食(派根饮食)后,大动脉容易发生动脉粥样硬化变化。我们的目的是在C57BL/6J背景下,使用无角SF-1敲除小鼠来检测性激素和性染色体补体对动脉粥样硬化斑块形成的影响。将性腺完整和青春期前性腺切除的WT和无角SF-1敲除的C57BL/6J小鼠暴露于派根饮食和对照饮食20周。我们监测了他们的体重、食物摄入和血脂状况。用表面法检查主动脉,并对主动脉球的横截面进行脂质含量染色。在所有小鼠组中,动脉粥样硬化的变化都很小,仅限于主动脉球。动脉粥样硬化斑块的形成依赖于性别和激素,因为卵巢功能正常的雌性动物形成了最显著的动脉粥样硬化斑块。性腺完整的雌性也是唯一一组在对照饮食或致动脉粥样硬化饮食中体重增加的群体。饮食影响血液生化,但各组之间的血脂水平几乎没有显著差异。结果表明,引起动脉粥样硬化性别依赖性差异的主要机制是性激素而非性染色体。我们的研究结果还表明,饮食诱导的动脉粥样硬化小鼠模型在研究人类动脉粥样硬化机制方面的作用有限,因为雌激素的存在会损害脂质代谢并导致动脉粥样硬化斑块的形成。雌激素DIETHIExtract:绝经后妇女患动脉粥样硬化的风险增加,因此雌激素保护血管免受这种血管疾病的发展是公认的。然而,尚未完全研究雌激素是否是主要因素,性染色体是否也受到影响,以及性激素的作用在哺乳动物中是否相同。研究动脉粥样硬化的动物模型很少见,其中一种是C57BL/6J小鼠,如果长期喂食高脂肪食物,并添加胆固醇和胆酸盐,即所谓的派根致动脉粥样硬化饮食,它们可以在身体的主要动脉中自发发生动脉粥样硬化变化。本研究的目的是研究性激素和性染色体对血管动脉粥样硬化斑块形成的影响,使用具有抑制的SF-1基因的小鼠模型,这些小鼠在没有性器官的情况下发育。在20周的时间里,给小鼠喂食派根规定的食物,或脂肪含量较低的对照食物。由于SF-1基因(背景C57BL/6J)灭绝,两性小鼠要么没有性器官,要么在青春期前切除性腺。三分之一的雄性和雌性性腺完好无损。我们监测了动物的体重、平均食物消耗量,并进行了血脂分析。我们使用单面法检查了准备好的主动脉,并通过组织学染色和显微镜图像分析评估了主动脉瓣水平处主动脉根横向切口中斑块和脂肪的程度。在喂食致动脉粥样硬化饮食的所有小鼠组中,动脉粥样硬化变化相对较小,仅限于主动脉根部。斑块的程度取决于染色体性别和激素的存在,斑块在有卵巢的女性中最为明显。同时,完整的雌性是唯一一组在致动脉粥样硬化食物和对照食物中体重增加相似的动物,其余在致动脉粥样硬化饮食中的动物生长明显较少。食物类型对血脂有影响,但不同动物组之间实际上没有统计学上的显著差异,血清分析也不能与在雌性中观察到的其他异常相关联。研究结果表明,动脉粥样硬化变化发展过程中性别差异的主要原因是性激素,而不是性染色体。与此同时,研究结果对小鼠模型在研究饮食诱导的动脉粥样硬化方面的有用性提出了质疑,因为与人类不同,小鼠体内雌激素的存在会对脂质代谢产生负面影响,并导致动脉粥样硬化斑块的形成。关键词:动脉粥样硬化;排根饮食;性别性激素;小鼠、脂质和胆固醇

This study aimed to compare the hemato-biochemical parameters in cats suffered from FLUTD with those of healthy cats, and to evaluate the inflammatory process by measuring serum amyloid A, alpha-1-Acid glycoprotein, and plasma fibrinogen concentrations. Cats frequently suffer from feline lower urinary tract disease (FLUTD), which causes acute renal failure, electrolyte buildup, and acid-base imbalance. Acute-phase proteins can be used to monitor the inflammatory processes of feline lower urinary tract disease.The present study included thirty cats of both sexes, nine cats defined as clinically healthy cats and 21 cats with signs of idiopathic cystitis and/ or urethral obstruction for up to 24 hours were defined as cat with FLUTD group. Blood samples were collected from cephalic vein for hematological, biochemical assays and the measurement of acute-phase protein concentrations, including SAA, AGP, and fibrinogen. Serum SAA and AGP were measured using commercial ELISA kits.In cats with FLUTD, the total white blood cell count, neutrophils, and platelets count increased significantly, as did the mean values of hematological and biochemical indices. However, there was a significant decrease in the mean value of red blood cells, hemoglobin, and PCV. Blood urea nitrogen, creatinine, total proteins, albumin, potassium, and phosphorus levels all increased significantly, while sodium and chloride levels decreased significantly. When compared to clinically healthy cats, plasma fibrinogen, serum alpha-1- acid glycoprotein, and serum amyloid A levels were significantly higher in cats with FLUTD. There was a significant positive correlation between the concentrations of acute phase proteins biomarkers (SAA, AGP, and fibrinogen) and blood urea nitrogen and creatinine. It is concluded that, in cats with FLUTD, serum amyloid A, AGP, and fibrinogen could be employed as an indicator of inflammatory processes.
本研究旨在比较患FLUTD的猫与健康猫的血液生化参数,并通过测量血清淀粉样蛋白A、α -1-酸性糖蛋白和血浆纤维蛋白原浓度来评估炎症过程。猫经常患有猫下尿路疾病(FLUTD),它会导致急性肾功能衰竭,电解质积聚和酸碱失衡。急性期蛋白可用于监测猫下尿路疾病的炎症过程。本研究包括30只雌雄猫,其中9只被定义为临床健康猫,21只出现特发性膀胱炎和/或尿道阻塞症状长达24小时的猫被定义为flud组。采集头静脉血样进行血液学、生化检测和急性期蛋白浓度测定,包括SAA、AGP和纤维蛋白原。血清SAA和AGP采用商用ELISA试剂盒检测。在患有FLUTD的猫中,白细胞总数、中性粒细胞和血小板计数显著增加,血液学和生化指标的平均值也显著增加。然而,红细胞、血红蛋白和PCV的平均值显著下降。血尿素氮、肌酐、总蛋白、白蛋白、钾、磷水平均显著升高,钠、氯水平显著降低。与临床健康猫相比,FLUTD猫的血浆纤维蛋白原、血清α -1-酸性糖蛋白和血清淀粉样蛋白A水平显著升高。急性期蛋白生物标志物(SAA、AGP、纤维蛋白原)浓度与血尿素氮、肌酐呈显著正相关。由此得出结论,在患有FLUTD的猫中,血清淀粉样蛋白A、AGP和纤维蛋白原可以作为炎症过程的指标。

Bluetongue (BT) is a non-contagious virus in the Reoviridae family that infects both wild and domestic animals. It causes economic losses and reduces infected animals' production and reproduction. A total of 233 apparently healthy animals were screened for BT. Profiles of health condition of animals were identified using multiple correspondence analysis (MCA) and hierarchical cluster analysis (HCA), and the impact of the change in disease condition of animals was explored by examining the subjective evaluation of the impact of risk factors like (age, sex, season, species, and locality) with regard to BT disease providing an insight into a dataset through information visualization and it presents a useful application for visualizing associations amongst variable categories. The first two MCA dimensions retained up to 27% of the total inertia contained in the data. The positive BT results, summer, and old animals categories were loaded in the first dimension, while negative cases, Al-mounfia and winter categories were related to the second dimension. HCA identified three clusters. Cluster 1 was characterized by frequent and largely exclusive seronegative BT animals 91.67 % of animals in the cluster were seronegative, negative BTV category is the most important and related to cluster 1 with positive v-test=8.75.  Cluster 3 can named a cluster of seropositive BT, up to 88% of cases were seropositive. We can conclude that seropositive BT is associated with summer and old age categories, whereas seronegative BT is associated with young age and winter categories, and thus MCA and HCA provide convenient and easy-to-interpret analytical tools for assessing categorical data relationships.
蓝舌病毒(BT)是呼肠孤病毒科的一种非传染性病毒,可感染野生动物和家畜。它会造成经济损失,并减少受感染动物的生产和繁殖。共筛选233只明显健康的动物进行BT筛查。使用多重对应分析(MCA)和层次聚类分析(HCA)鉴定动物的健康状况,通过检查风险因素(如年龄、性别、季节、物种和地点)对BT疾病影响的主观评估,探索了动物疾病状况变化的影响,通过信息可视化提供了对数据集的深入了解,并为可视化变量类别之间的关联提供了有用的应用。前两个MCA尺寸保留了数据中包含的总惯性的27%。阳性BT结果、夏季和老年动物类别加载在第一维度,而阴性病例、Al mounfia和冬季类别与第二维度相关。HCA确定了三个集群。集群1的特点是频繁且主要是排他性的血清阴性BT动物。集群中91.67%的动物是血清阴性的,阴性BTV类别是最重要的,与集群1相关,阳性v测试=8.75。集群3可以命名为血清阳性BT集群,高达88%的病例是血清阳性。我们可以得出结论,血清阳性BT与夏季和老年类别相关,而血清阴性BT与年轻和冬季类别相关,因此MCA和HCA为评估分类数据关系提供了方便和易于解释的分析工具。

An abattoir survey was conducted from October 2020 to September 2021 to identify the primary reasons for offal and carcass condemnation of slaughtered animals in Dakahlia province, Egypt, as well as to estimate their economic loss. During the survey, 643 animals (441 cattle, 178 buffalos, 19 camels, 4 sheep, and one goat) were submitted for antemortem and postmortem inspection. The results of both inspections were collected, analyzed, and the total economic loss was estimated by adding the condemnation of offal and carcasses over a twelve-month period. Retail prices for offal (liver, lung, heart, and tongue) and carcass prices per kg were obtained from local markets. Out of 643 animals slaughtered, 2 (0.31%) were totally condemned. In addition, postmortem inspection revealed that 217 (33.74%) livers, 158 (24.57%) lungs, 5 (0.78%) hearts, 14 (2.18%) heads, and 11(1.71%) tongues were condemned. Offal were condemned mainly due to pneumonia, fascioliasis, telangiectiasis, necrosis, and hydatidosis, whereas carcasses were rejected due to generalized tuberculosis. According to this study, the financial loss at the abattoir owing to carcass and organ condemnations was 244066 Egyptian Pounds over a twelve-month period (15746 USD). The incidence of meat rejection and subsequent financial loss was high compared to the amount of local revenue. The current study concluded that bacterial and parasitic diseases are still prevalent and cause significant economic damage in Dakahlia province, Egypt. This abattoir survey offered regional information on the principal reasons for carcass and organ condemnation in slaughtered animals, as well as an estimate of the direct economic consequences. Furthermore, the findings of the current work underlined the importance of developing an efficient monitoring system for meat condemnation and enforcing animal health strategies in Egypt.
2020年10月至2021年9月进行了一项屠宰场调查,以确定埃及达喀利亚省屠宰动物内脏和胴体被谴责的主要原因,并估计其经济损失。在调查中,643只动物(441头牛、178头水牛、19头骆驼、4只绵羊和1只山羊)被提交进行了死前和死后检查。收集和分析了两次检查的结果,并通过在12个月期间对内脏和尸体进行谴责来估计总经济损失。内脏(肝、肺、心脏和舌头)的零售价格和每公斤胴体的价格均来自当地市场。在被屠宰的643只动物中,有2只(0.31%)被完全谴责。另外,尸检结果显示,有217个肝脏(33.74%)、158个肺(24.57%)、5个心脏(0.78%)、14个头部(2.18%)、11个舌头(1.71%)被判死刑。动物内脏主要因肺炎、片形吸虫病、毛细血管病、坏死和包虫病而被拒绝,而胴体则因全身性肺结核而被拒绝。根据这项研究,在12个月的时间里,由于胴体和器官的谴责,屠宰场的经济损失为244066埃及镑(15746美元)。与当地的收入相比,肉类拒食的发生率和随后的经济损失很高。目前的研究得出的结论是,细菌和寄生虫病在埃及达卡利亚省仍然普遍存在,并造成重大的经济损失。这项屠宰场调查提供了关于被屠宰动物尸体和器官遭到破坏的主要原因的区域信息,以及对直接经济后果的估计。此外,目前工作的结果强调了在埃及建立一个有效的肉类谴责监测系统和执行动物卫生战略的重要性。

Furthermore, the findings of the current work underlined the importance of developing an efficient monitoring system for meat condemnation and enforcing animal health strategies in Egypt.","PeriodicalId":21765,"journal":{"name":"Slovenian Veterinary Research","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45465043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dromedary camels (Camelus dromedarius) are adapted to their desert habitat where they are able to survive and reproduce despite very high temperatures, little vegetation, and limited water availability. The mechanism of thermoregulation in camels is highly efficient, which makes them maintain the appropriate body temperature to carry out their physiological activities. Compared to other mammals, camels are environmentally tolerant as they can be bred for milk and meat production in areas with scant natural resources depending on their unique physiological, anatomical and behavioral characteristics. The camel's digestive system has unique morphological features that make it highly adapted to its natural environment. Although the stomach of camels is divided into compartments, as in ruminants, they are referred to as pseudo-ruminants because they do not have the clearly divided four-chambered stomach found in true ruminants. However, their stomach is larger and more efficient in dealing with dry, tough, and fibrous food. Therefore, the current study aimed to review the gross anatomical and histological peculiarities and characteristic features of the dromedary camel stomach with respect to their physiological importance. The morphological characterization of the dromedary camel stomach might elucidate the functions of its different compartments. Thus, this review could add to our understanding of the physiology of the digestive system in dromedary camels.
单峰骆驼(Camelus dromedarius)适应了它们的沙漠栖息地,在那里,尽管温度非常高,植被很少,水供应有限,它们仍能生存和繁殖。骆驼的体温调节机制是高效的,使其保持适当的体温来进行生理活动。与其他哺乳动物相比,骆驼具有环境耐受性,因为它们可以根据其独特的生理、解剖和行为特征,在自然资源匮乏的地区养殖,以生产牛奶和肉类。骆驼的消化系统具有独特的形态特征,使其高度适应自然环境。虽然骆驼的胃像反刍动物一样被分成小室,但它们被称为伪反刍动物,因为它们没有真正反刍动物那样被清楚地分成四室的胃。然而,他们的胃更大,更有效地处理干燥,坚韧和纤维食物。因此,本研究旨在综述单峰骆驼胃的大体解剖和组织学特征及其生理重要性。单峰骆驼胃的形态特征可能阐明其不同胃室的功能。因此,这一综述可以增加我们对单峰骆驼消化系统生理学的理解。
