Vegetables are rich sources of vitamins, minerals and fibres. They have beneficial anti-oxidative effects. The consumption of vegetables containing heavy metals is a significant cause of many diseases. In this study, the concentrations of heavy metals in the frequently consumed vegetables sold in Gwagwalada central market , Abuja, Nigeria was investigated. Quantitative analysis of heavy metals was done using Atomic Absorption Spectrophotometer (AAS). The concentration level of lead showed that cucumber, cabbage, banana, lettuce, green peas, carrot, and onion had 8.65 ± 1.1, 0.0, 100.40 ± 10.0, 68.00 ± 7.0, 64.76 ± 5.8, 61.28 ± 5.6, and 8.92± 1.1, respectively. There was no traceable level of nickel in the fruits and vegetables while cadmium was observed to be 0.10 ± 0.1 in cabbage alone. The study showed that the fruits and vegetables sampled were contaminated with heavy metals higher than the WHO permissible limits.
蔬菜富含维生素、矿物质和纤维。它们有有益的抗氧化作用。食用含有重金属的蔬菜是许多疾病的重要原因。在这项研究中,调查了尼日利亚阿布贾瓜瓦拉达中心市场销售的经常食用的蔬菜中的重金属浓度。采用原子吸收分光光度法(AAS)对重金属进行定量分析。黄瓜、白菜、香蕉、生菜、青豆、胡萝卜、洋葱的铅浓度分别为8.65±1.1、0.0、100.40±10.0、68.00±7.0、64.76±5.8、61.28±5.6和8.92±1.1。水果和蔬菜中没有可追溯的镍含量,而仅白菜中镉含量为0.10±0.1。研究显示,抽样的水果和蔬菜重金属含量高于世界卫生组织允许的限度。

Ruminant welfare post-surgery could be improved by employing a procedural technique that causes minimal surgical stress. A total of twenty-four (n = 24) Kano Brown goats (KBGs) aged 1–2 years, weighing an average of 15.52 kg, were recruited for the study. Rumen skin clamp fixation (RSCF) and a stay suture rumenotomy (SSR) in lateral recumbency while standing restraint rumenotomy was aided by a locally fabricated mobile small ruminant surgical chute (MSRSC) were performed in groups A, B, and D, respectively, as control group C had no surgery. Six goats were allocated to each group such that each group had 3 males and females that were positive for rumen foreign body impaction (RFBI), except goats in group C that were free of RFBI. Pre- and post-rumenotomy values of vital parameters did not differ significantly (P > 0.05). The group A serum IL-6 concentrations at 72 hours post-rumenotomy (61.21 ± 44.52 ng/L) were significantly higher (P < 0.05) than those in group D (15.24 ± 3.09 ng/L) among the female KBGs. The concentrations of IL-6 at week 1 post-rumenotomy in group A were significantly higher (65.05 ± 31.11 ng/L) than in groups B (15.86 ± 0.29), D (18.75 ± 5.81) and C (14.86 ± 0.79 ng/L). The lack of significant changes in the mean values of rectal temperature, respiratory rate, and heart rate implies that the standing rumenotomy utilizing the MSRSC did not vary in surgical stress severity from the conventional approaches; RSCF and SSR, done in lateral recumbency. The IL-6 in group D was lower when compared to the values in group A females at 72 hours and at week 1 for the male KBGs, suggesting profound surgical stress among females and males in groups A and B over group D. Standing restraints cause less surgical stress than lateral recumbency restraints, making it a better procedural approach for rumenotomy in goats.
手术后反刍动物的福利可以通过采用一种程序技术来改善,这种技术可以减少手术压力。试验选用24只1-2岁的卡诺棕色山羊(KBGs),平均体重15.52 kg。a组、B组和D组分别采用侧卧位瘤胃皮钳固定(RSCF)和固定缝线切除瘤胃(SSR),并辅以局部制作的移动小反刍动物手术滑道(MSRSC)进行站立约束切除瘤胃,对照组C不进行手术。每组6只,除C组无瘤胃异物嵌塞外,每组各有3只公母瘤胃异物嵌塞(RFBI)阳性。瘤胃切除前后各重要参数值差异无统计学意义(P > 0.05)。A组女性KBGs切除后72h血清IL-6浓度(61.21±44.52 ng/L)显著高于D组(15.24±3.09 ng/L) (P < 0.05)。A组IL-6浓度(65.05±31.11 ng/L)显著高于B组(15.86±0.29)、D组(18.75±5.81)和C组(14.86±0.79)ng/L。直肠温度、呼吸频率和心率的平均值没有显著变化,这意味着使用MSRSC的站立式瘤胃切除术在手术压力严重程度上与传统入路没有差异;侧卧位RSCF和SSR。与A组相比,D组雌性在72小时和第1周时的IL-6值较低,表明A组和B组雌性和雄性的手术压力比D组大。站立约束比侧卧约束造成的手术压力更小,使其成为山羊瘤胃切除术的更好的手术方法。

Dermatophytes produce keratinases that dissolve the keratinous tissues of the skin and hairs; inflammation is caused by the host’s response to metabolic by products. The aim of this study was to isolate and identify dermatophytes from the skin of cattle presented for slaughter at Zango abattoir, Zaria, Nigeria. Samples were aseptically collected from twenty (20) cattle, cultured at room temperature for one to four weeks in Sabouraud’s Dextrose Agar (SDA). Growth from pure SDA cultures were sub-cultured on Potato dextrose agar and further incubated at room temperature for one to four weeks. Twelve animals were positive for dermatophytes either by microscopy, culture or both, thus producing an incidence of 60% with respect to the total number of the samples investigated (20). One (1) sample was positive by microscopy but eleven (11) were positive by both microscopy and culture. A large spectrum of dermatophytes consisting of eight species were recovered in the study. They were mostly zoophilic species which included M. canis, T. mentagrophytes, T. verrucosum, M. distortum and T. gallinae. Others were Geophilic specie (M. gypseum) and Anthropophilic species (T. soudanense and T. rubrum). M. canis was the most predominant species consisting of 41.7%. This study clearly demonstrated that cattle dermatophytoses in the study location was caused by different dermatophyte species with M. canis as the most prevalent. Some of the organisms are zoonotic, with public health relevance to animal handlers and butchers.
皮肤植物产生角化酶,溶解皮肤和头发的角化组织;炎症是由宿主对代谢副产物的反应引起的。本研究的目的是从尼日利亚Zaria Zango屠宰场供屠宰的牛皮肤中分离和鉴定皮肤真菌。从二十(20)头牛中无菌采集样品,在Sabouraud 's Dextrose Agar (SDA)中室温培养一至四周。将纯SDA培养物在马铃薯葡萄糖琼脂上继代培养,并在室温下进一步培养1至4周。12只动物通过显微镜、培养或两者均呈皮肤真菌阳性,因此,相对于所调查样本的总数,发病率为60%(20)。1例镜检阳性,11例镜检和培养均阳性。在研究中发现了大量的皮肤真菌,包括8种。其中以嗜兽种居多,包括犬支原体(M. canis)、mentagrophytes、疣状支原体(T. verrucosum)、扭曲支原体(M. distortum)和鸡支原体(T. gallinae)。其余为嗜地种(M. gypseum)和嗜人种(T. soudanense和T. rubrum)。犬支原体为优势种,占41.7%。本研究清楚地表明,研究地点的牛皮肤真菌是由不同种类的皮肤真菌引起的,其中以犬支原体最常见。其中一些生物是人畜共患的,与动物处理者和屠夫的公共卫生有关。

Foot and Mouth Disease is a contagious viral disease of cattle and sheep, causing ulceration of the hoofs and around the mouth. The role of small ruminants in FMD epidemiology is still poorly understood in Nigeria. The aim of the study is to determine the prevalence of Foot and Mouth Disease Virus (FMDV) antibodies in sheep and goats slaughtered in Karu abattoir. One hundred and twenty (120) sera each were collected from both sheep and goats and screened for FMDV antibodies using 3ABC ELISA. The result showed that 89 (74.2) of the sheep sera screened were positive for FMDV antibodies whereas 103 (85.8) of the goat sera were positive. It was more prevalent in goats. The finding indicates a characteristic maintenance host nature for FMD virus in small ruminants without apparent clinical signs. This study suggested an on-going infection in small ruminant co-herding with cattle as a risk factor. This risk factor may enhance FMD transmission associated with increased movement of infected live animals from endemic states to markets and abattoirs following livestock trade activities. FMD is a Transboundary Animal Disease (TAD) affecting livestock production and disrupting regional and international trade in animals and animal products. The detection of FMD antibodies in sheep and goats slaughtered in Karu abattoir suggests small ruminants play important roles in the epidemiology of Foot and Mouth Disease in Nigeria. Good tracking of origin and proper surveillance system for FMD in animals brought into the abbatoir to be slaughtered are recommended for a comprehensive prevention and control of the disease.
口蹄疫是牛羊的一种传染性病毒性疾病,可引起蹄部和口周溃烂。在尼日利亚,人们对小反刍动物在口蹄疫流行病学中的作用仍然知之甚少。该研究的目的是确定在卡鲁屠宰场屠宰的绵羊和山羊中口蹄疫病毒抗体的流行情况。采集绵羊和山羊各120份血清,用3ABC ELISA法筛选FMDV抗体。结果显示,绵羊血清中FMDV抗体阳性89份(74.2份),山羊血清中FMDV抗体阳性103份(85.8份)。在山羊中更为普遍。这一发现表明口蹄疫病毒在小反刍动物中具有特征性的维持性宿主,没有明显的临床症状。本研究表明,与牛共同放牧的小反刍动物持续感染是一个危险因素。这一风险因素可能会加强口蹄疫的传播,因为在畜牧贸易活动之后,受感染的活禽从流行国家向市场和屠宰场的流动增加。口蹄疫是一种跨界动物疾病,影响牲畜生产,扰乱动物和动物产品的区域和国际贸易。在Karu屠宰场屠宰的绵羊和山羊中检测到口蹄疫抗体表明,小型反刍动物在尼日利亚口蹄疫流行病学中发挥了重要作用。为全面预防和控制口蹄疫,建议对进入屠宰场屠宰的动物进行良好的来源追踪和适当的监测系统。

Land filling is a common method of managing solid wastes around the world and this method of waste management causes nuisance to the environment through the release of chemical laden landfill gases and leachates that can affect multiple organ systems including the male reproductive system. This study was carried out to investigate the impact of 21 days exposure of Gwagwalada landfill leachate on sexual behaviour, reproductive hormonal imbalance, gonadal and extra-gonadal sperm reserve depletion and histopathology of the testis and epididymis of adult male Wistar rats. Twenty (20) adults male Wistar rats were used and randomly selected into two (2) groups. Group A were fed with normal rat chow and tap water as drinking water ad libitum while Group B were fed with normal rat chow and 10% of Gwagwalada landfill leachate as drinking water ad libitum. Exposure was for 21 days. Results showed that exposure to GLL induced decreased mount frequency and increased mount latency as well as decreased serum concentrations of LH, FSH and testosterone. Also, there was marked weight loss of the testis (especially the left) with different morpho-phenotypic pathologies of the testis and epididymis. The present study has demonstrated the detrimental effects of Gwagwalada landfill leachate to adult males.
填埋是世界各地管理固体废物的一种常用方法,这种废物管理方法通过释放含有化学物质的填埋气体和渗滤液对环境造成滋扰,可以影响包括男性生殖系统在内的多个器官系统。本研究旨在探讨Gwagwalada垃圾渗滤液暴露21 d对成年雄性Wistar大鼠性行为、生殖激素失衡、性腺和性腺外精子储备衰竭以及睾丸和附睾组织病理学的影响。选用成年雄性Wistar大鼠20只,随机分为两组。A组以正常鼠粮和自来水作为随意饮水,B组以正常鼠粮和10%的瓜瓦拉达垃圾渗滤液作为随意饮水。暴露21天。结果表明,暴露于GLL会导致小鼠挂载次数减少,挂载潜伏期增加,血清LH、FSH和睾酮浓度降低。此外,睾丸(尤其是左侧)体重明显减轻,并伴有不同形态表型的睾丸和附睾病变。本研究证明了瓜瓦拉达垃圾渗滤液对成年雄性的有害影响。

Neoplasms constitute a major health challenge in animals and man worldwide. However, to the best of our knowledge, the prevalence of neoplasms in companion animals in Abuja, Nigeria, has not been determined. This study was therefore conducted to determine the prevalence of neoplasms in companion animals in Abuja, Nigeria. Case records from 2015 to 2020 from two renowned Veterinary Clinics in Abuja, were examined for cases of neoplasms. Data on the species, breed, sex, age, month and year of occurrence, organ(s) affected, methods of diagnosis, and treatment approach, were extracted and summarized into percentages. A total of 24 cases were recorded with 21 (87.5%) in dogs and 3 (12.5%) in cats. The highest prevalence of neoplasms was in German Shepherd (19.1%) followed by Boerboel (14.3%) and Caucasian (9.5%). In dogs, the prevalence of neoplasms was higher in males (57.1%) than females (42.9%), whereas in cats, the prevalence was higher in females (66.7%) than males (33.3%). The mean age of dogs diagnosed with neoplasms in this study was 6.56 years (SEM=1.21) while the mean age of affected cats was 10 years (SEM=0.00). The commonest types of neoplasms in dogs were papilloma (38.1%) and mast cell tumor (28.6%). The three neoplasms diagnosed in cats were mammary gland carcinoma (33.3%), lipoma (33.3%), and fibrosarcoma (33.3%). In dogs, 90.5% of the cases of neoplasms were diagnosed by physical examination only. However, in addition to physical examination in cats, 66.7% of the cases of neoplasms were diagnosed by histopathology, while 33.3% of the cases were diagnosed by ultrasonography. In this study, surgical excision was the commonest method of treatment of neoplasms in both dogs (76.2%) and cats (66.7%). There is a need for the provision of diagnostic facilities to aid the confirmatory diagnosis of neoplasms in dogs and cats in the study area.
肿瘤是全世界动物和人类面临的一个重大健康挑战。然而,据我们所知,尼日利亚阿布贾的伴侣动物中肿瘤的流行程度尚未确定。因此,进行这项研究是为了确定尼日利亚阿布贾的伴侣动物中肿瘤的患病率。对阿布贾两家著名兽医诊所2015年至2020年的病例记录进行了肿瘤病例检查。提取有关种类、品种、性别、年龄、发生月份和年份、受累器官、诊断方法和治疗方法的数据,并汇总成百分比。共24例,其中犬21例(87.5%),猫3例(12.5%)。德国牧羊犬的发病率最高(19.1%),其次是布尔波尔犬(14.3%)和高加索犬(9.5%)。在狗中,男性的肿瘤患病率(57.1%)高于女性(42.9%),而在猫中,女性的患病率(66.7%)高于男性(33.3%)。本研究中诊断为肿瘤的狗的平均年龄为6.56岁(SEM=1.21),而受影响的猫的平均年龄为10岁(SEM=0.00)。犬中最常见的肿瘤类型为乳头状瘤(38.1%)和肥大细胞瘤(28.6%)。在猫中诊断出的三种肿瘤是乳腺癌(33.3%)、脂肪瘤(33.3%)和纤维肉瘤(33.3%)。在狗中,90.5%的肿瘤病例仅通过体格检查被诊断出来。然而,在猫的体格检查中,66.7%的肿瘤是通过组织病理学诊断的,而33.3%的病例是通过超声诊断的。在本研究中,手术切除是狗(76.2%)和猫(66.7%)最常见的肿瘤治疗方法。有必要提供诊断设施,以帮助研究地区的狗和猫的肿瘤确诊。

Clarias gariepinus catfish is an important fish farmed in West African. However, the successful culture of this fish is hampered by the ever-increasing cost of feed. Study was conducted to exploit the compensatory growth patterns that has been reported in fish and to determine the effects of intermittent feed deprivation and refeeding on the production performance of juvenile Clarias gariepinus. One hundred and sixty (160) juvenile fish (80 ± 23 g; 23.55 ± 7.31 cm) were randomly distributed into four 200-liter aquaria labeled A, B, C and D. Fish in group A (the control) were fed continuously; fish in group B, were subjected to a 3-days feed deprivation and 3-days refeeding regimen; fish in group C, were subjected to a 5-days feed deprivation and 5-days refeeding regimen; and fish in group D were subjected to a 5-days feed deprivation and 7-days refeeding regimen. Growth parameters were measured in all groups for 98 days. Results shows that there were no significant variations (p > 0.05) in the final weight gained by fish in group B compared to fish in group A. Fish in groups C and D exhibited compensatory growth and had significantly higher weight gains compared to fish in group A. Fish in group B exhibited the highest compensation coefficient of 2.348 compared with 2.212 and 1.287 for groups C and D respectively. It is concluded that juvenile Clarias gariepinus can be produced following a feed deprivation and refeeding regimen, without significantly affecting its growth and production performance. The economic implication of this strategy is that production can be maximized while significantly reducing the cost of feeding. It is recommended that a 5-days feed deprivation and 5-days refeeding regimen be employed as this results in high weight gain at a reduced cost.
Clarias gariepinus鲶鱼是西非重要的养殖鱼类。然而,这种鱼的成功养殖受到不断增加的饲料成本的阻碍。本研究旨在探索已报道的鱼类代偿性生长模式,并确定间歇性断食和复食对加里平Clarias gariepinus幼鱼生产性能的影响。160条幼鱼(80±23克);23.55±7.31 cm),随机分为A、B、C、d 4个200升水族箱,A组(对照组)连续饲喂;B组分别饲喂3 d剥夺饲料和3 d复饲;C组进行5 d禁饲和5 d复饲;D组分别饲喂剥夺5 D、复喂7 D。98 d时测定各组的生长参数。结果表明,B组鱼的最终增重与a组鱼无显著差异(p > 0.05)。C组和D组鱼表现出代偿性生长,增重显著高于a组。B组鱼的代偿系数最高,分别为2.348和2.212,而C组和D组的代偿系数分别为1.287。综上所述,通过禁饲再投喂,可在不显著影响其生长和生产性能的情况下养殖加里平Clarias gariepinus幼鱼。这一战略的经济意义是,在显著降低饲养成本的同时,可以最大限度地提高产量。建议采用5天禁饲和5天复饲方案,因为这样可以以较低的成本获得较高的增重。

Peptic ulcer disease is one of the commonest gastrointestinal diseases in the world and several orthodox drugs have been employed for the treatment of this disease. Although effective, some of these drugs produce adverse effects with a great tendency for the disease to reoccur. Hence, the need for further screening of medicinal plants for potential antiulcer activity and as sources for antiulcer lead compounds. Andira inermis is one of the plants identified to be used traditionally in ulcer-related conditions. This research work was aimed at evaluating the peptic ulcer-protective effects of aqueous-methanol stem bark extract of A. inermis in rats with acetylsalicylic acid and cold stress-induced ulceration. Adult Wistar rats were grouped into 5 of five rats each. Rats in Group A were administered normal saline (30 ml/kg i.p) to serve as the negative control. Rats in groups B, C and D were pretreated with the graded doses of the extract (100, 200 and 400 mg/kg i.p). Rats in group E were treated with Cimetidine (100 mg/kg i.p) to serve as the positive control group. Thirty minutes post-treatment, ulceration was induced with acetylsalicylic acid (150 mg/kg p.o) and all the rats were subjected to cold restrain stress for a 4h period. The rats were then sacrificed humanely and their stomachs were excised for gross examination and scoring of ulcer indices. The mean ulcer indices, percentage severity of ulceration and percentage ulcer protection were determined using corresponding calculations. The results revealed that acetylsalicylic acid combined with cold stress caused mostly marked congestion, gross erosions and deep ulcers with ecchymotic and petechial hemorrhages on the gastric mucosa of the rats treated with normal saline (30 ml/kg i.p.). The aqueous methanol stem bark extract of A. inermis significantly (p < 0.05) inhibited the formation of these lesions. The extract caused increased secretion of mucous on the gastric mucosa of rats and a dose-dependent reduction in ulcer indices. This was significant (p < 0.05) at the dose of 400 mg/kg i.p of the extract. The extract, at graded doses of 100, 200 and 400 mg/kg i.p produced percent ulcer protection of 60.0%, 73.3%, and 80.0% respectively. This was comparable to Cimetidine which showed a percent ulcer protection of 86.7%. This shows that the stem bark extract of Andira inermis possesses gastro-protective effects and has the potential to be developed as an agent for the treatment of peptic ulcers..
消化性溃疡是世界上最常见的胃肠道疾病之一,目前已有几种传统药物用于治疗此病。虽然这些药物有效,但其中一些药物会产生不良反应,使疾病复发的可能性很大。因此,有必要进一步筛选具有潜在抗溃疡活性的药用植物,并作为抗溃疡铅化合物的来源。Andira inermis是一种被确定用于溃疡相关疾病的传统植物。本研究旨在探讨水甲醇提取物对乙酰水杨酸和冷应激致溃疡大鼠消化性溃疡的保护作用。成年Wistar大鼠5只,每组5只。A组大鼠给予生理盐水30 ml/kg i.p作为阴性对照。B、C、D组大鼠分别用100、200、400 mg/kg i.p的分级剂量进行预处理。E组大鼠给予西咪替丁(100 mg/kg i.p)治疗作为阳性对照组。治疗30 min后,用乙酰水杨酸(150 mg/kg p.o)致溃疡,进行冷抑制应激4h。然后人道处死大鼠,切除胃进行大体检查和溃疡指数评分。采用相应的计算方法测定平均溃疡指数、溃疡严重程度百分比和溃疡保护百分比。结果表明,乙酰水杨酸联合冷应激对生理盐水(30 ml/kg i.p)处理的大鼠胃粘膜造成明显的充血、严重糜烂和深部溃疡,并伴有瘀斑出血。甲醇水提物显著(p < 0.05)抑制了这些病变的形成。该提取物引起大鼠胃粘膜粘液分泌增加,溃疡指数呈剂量依赖性降低。在剂量为400 mg/kg i.p时,差异有统计学意义(p < 0.05)。在100,200和400mg /kg i.p的分级剂量下,溃疡保护率分别为60.0%,73.3%和80.0%。这与西米替丁相当,西米替丁的溃疡保护率为86.7%。这表明,Andira inermis茎皮提取物具有胃保护作用,并有潜力被开发为消化性溃疡的治疗剂。

Naturally mated and artificially inseminated Japanese quail (Coturnix japonica) hens’ eggs reproductive indices were investigated to evaluate natural mating or artificial insemination techniques for breeding quails in local farms. A total of 141 (108 hens and 33 cocks) matured quails of about 11 weeks of age were used for the experiment, of which 54 hens were inseminated with Citric-quail egg albumen extended semen collected from 15 fertile cocks. Another 54 hens were naturally mated by another 18 fertile cocks in a ratio of one cock to three hens (1:3). Eggs collected from both naturally mated and artificially inseminated birds were incubated for 18 days. The percentage of incubated eggs that were fertile when candled on the 7th and 12th day and hatch-out analysis after the 18th day of incubation tested fertility. Hatchability was tested by the percentage number of fertile eggs that hatched. Naturally mated and artificially inseminated hens’ eggs had a fertility of 84.0 % and 73.3 %, and a hatchability of 82.5 % and 85.5 %, respectively. The study revealed no significant difference in the frequency of fertile or hatched Japanese quail eggs (χ2 cal < χ critical at 5% or 1% level of probability). Naturally mated and artificially inseminated birds had relative fertile egg rates of 53.4 % and 46.6 %, respectively, and relative egg hatching rates of 52.5% and 47.5 %, respectively. Artificial insemination had the advantage of introducing the same volume of semen to more quail hens than a single cock in a natural mating process. However, natural mating was recommended over artificial insemination in the study area because of the technical constraints that required more workforce and amenities in the insemination process. The authors recommended research on developing restraint instruments and non-electrical semen storage methods for quail birds. The authors also proposed a restraint model for quail birds
通过对日本鹌鹑(Coturnix japonica)自然交配和人工授精母鸡的卵子生殖指数进行研究,评价自然交配和人工授精技术在当地鹌鹑养殖中的应用。试验选用11周龄左右的成熟鹌鹑141只(母鸡108只,公鸡33只),其中54只母鸡用15只可育公鸡的柠檬鹌鹑蛋蛋白扩展精液进行受精。另有54只母鸡由另外18只可生育的公鸡自然交配,比例为1公3母(1:3)。从自然交配和人工授精的鸟类中收集鸡蛋,孵育18天。第7天和第12天的孵卵率和第18天的出孵率测定了孵卵率。可孵化性是通过孵化出的受精卵的百分比来测试的。自然配种和人工授精的鸡蛋受精率分别为84.0%和73.3%,孵化率分别为82.5%和85.5%。研究显示,日本鹌鹑受精卵和孵化蛋的频率无显著差异(χ2 cal < χ在5%或1%概率水平上的临界值)。自然交配和人工授精的相对受精率分别为53.4%和46.6%,相对孵蛋率分别为52.5%和47.5%。人工授精的优点是,在自然交配过程中,与一只公鸡相比,它可以向更多的鹌鹑母鸡提供相同数量的精液。然而,由于技术限制,在人工授精过程中需要更多的劳动力和便利设施,因此在研究区域推荐自然交配而不是人工授精。作者建议研究开发鹌鹑约束仪器和非电性精液储存方法。作者还提出了一个鹌鹑约束模型

Dried crayfish are known to be important for human nutrition. Four hundred samples of dried `crayfish were purchased from six different markets and taken to bacterial zonooses laboratory for evaluation of microbial quality. Samples were analysed for bacterial load counts using standard microbiological methods. Total aerobic plate counts ranged from 6.74 ± 0.53 log10cfu/g for Bwari and 8.23 ± 0.36 log10cfu/g for Garki respectively, while total coliform counts ranged from 7.73 ± 0.48 logcfu/g for Gwagwalada to 8.31± 0.22 log10cfu/g for kubwa respectively. The common genera of bacterial isolated were Staphylococcus species (298;74.5%) and Streptococcus species (242;60.5%), Escherichia coli (230; 57%) Bacillus species (212;53%), Salmonella spcies (196; 49%) and Pseudomonas species (188; 47%). Overall, the highest value 8. 31 ± 0.22logcfu/g was obtained for both aerobic plate count and coliform counts which is much higher than the reference value of 5.7log10cfu/g for International commission on microbiological specification for food. This therefore highlights the need to improve the processing, handling, distribution, storage and transportation of dried crayfish in other to enhance consumer safety.
众所周知,干小龙虾对人体营养很重要。从六个不同的市场购入400份干小龙虾样本,送往细菌传染病实验室进行微生物质量评估。使用标准微生物学方法对样品进行细菌负荷计数分析。Bwari和Garki的需氧板总计数分别为6.74±0.53 log10cfu/g和8.23±0.36 log10cfu/g,而Gwagwalada和kubwa的大肠菌群总计数分别为7.73±0.48 log10cfu/g和8.31±0.22 log10cfu/g。检出的常见细菌属有葡萄球菌(298种,占74.5%)、链球菌(242种,占60.5%)、大肠杆菌(230种;芽孢杆菌212种,53%;沙门氏菌196种;49%)和假单胞菌种(188;47%)。总的来说,最高值为8。好氧平板计数和大肠菌群计数均为31±0.22logcfu/g,远高于国际食品微生物规范委员会的参考值5.7log10cfu/g。因此,有必要改进干燥小龙虾的加工、处理、分销、储存和运输,以提高消费者的安全。

This therefore highlights the need to improve the processing, handling, distribution, storage and transportation of dried crayfish in other to enhance consumer safety.","PeriodicalId":17442,"journal":{"name":"Journal of Veterinary and Biomedical Sciences","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84354783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
