Cross-sectional study design was implemented in Alage dairy farm to determine the overall prevalence of mastitis, its causative agents, susceptibility patterns and risk factors associated with it. A total of 111 milking dairy cows and 444 quarters were examined. Overall prevalence of mastitis at cow and quarter levels were 73 and 37%, respectively. Coagulase negative staphylococci (CNS) (37.7%) followed by Staphylococcus aureus (19.6%), Escherichia coli (9.4%), Staphylococcus intermidius (9.4%), Bacillus species (8%), Streptococcus species (5.8%), Klebsiella pneumoniae (5.8%), and Enterobacter aerogens (4.3%) were isolated in that order of decreasing frequency. From a total of seven antibiotics tested, most isolates were sensitive to Norfloxacin but showed resistance to Ampicillin. Age, stage of lactation, milk yield, hygiene score, feet problems and udder conformation were found to be risk factors significantly (P<0.05) associated with mastitis. The high prevalence rate of mastitis in a relatively well managed dairy farm implied that, it is the trickiest health problem of dairy cows that needs continued and concerted efforts in its fight. Key words: anti-biogram, mastitis, pathogens, prevalence, risk factors.
在Alage奶牛场实施横断面研究设计,以确定乳腺炎的总体患病率、其病原体、易感模式和与之相关的危险因素。共有111头奶牛和444个季度接受了检查。奶牛和四分之一奶牛乳腺炎的总体患病率分别为73%和37%。凝固酶阴性葡萄球菌(CNS)占37.7%,其次是金黄色葡萄球菌(19.6%)、大肠杆菌(9.4%)、中间葡萄球菌(9.4%)、芽孢杆菌(8%)、链球菌(5.8%)、肺炎克雷伯菌(5.8%)和产氧肠杆菌(4.3%)。从总共7种抗生素中,大多数分离株对诺氟沙星敏感,但对氨苄西林耐药。年龄、泌乳阶段、产奶量、卫生评分、足部问题和乳房构象是乳腺炎的危险因素(P<0.05)。在一个管理相对良好的奶牛场,乳房炎的高流行率意味着,这是奶牛最棘手的健康问题,需要持续和一致的努力来解决。关键词:抗菌谱,乳腺炎,病原体,患病率,危险因素。

This study was conducted in Gena Bossa district with the objective of assessing the productive and reproductive performance of indigenous chickens. Multistage stratified purposive and random sampling methods were used and a total of 138 households were interviewed in the study area. Fifteen, fifty four and sixty nine farmers selected for interviews from highland, midland and lowland agro-ecologies, respectively. From the interviewed farmers, 47, 47 and 44 farmers were poor, medium and rich wealth leveled, respectively. Farmers were categorized to their education level and 34, 34, 35 and 35 respondents were interviewed from illiterate, reading and writing, primary first and primary second cycle education level, respectively. Age at sexual maturity of pullets and cockerels were 5.64 and 5.25 months, respectively. The clutch number, eggs per clutch and total eggs/hen/year were 3.04, 12.78 and 38.53, respectively. In this survey, hatchability and survival rate of chicks were 81.72 and 38.85%, respectively. Sexual maturity, number of eggs per clutch and hatchability were significantly (p 0.05) different at different wealth levels of farmers. Generally, low productive and reproductive performance of indigenous chickens were recorded under farmer’s management condition in Gena Bossa District of Dawro Zone which needs further improvement from the government by organizing trainings for farmers on  disease control, housing and feeding of chickens to improve productive and reproductive performance. Key words: Agro-ecology, education level, wealth status, productive and reproductive performance, Indigenous chickens, Gena Bossa.
本研究在Gena Bossa地区进行,目的是评估本地鸡的生产和繁殖性能。采用多阶段分层目的和随机抽样的方法,对研究区138户家庭进行了访谈。分别从高原、中部和低地农业生态区选取15、54和69名农民进行访谈。在受访农户中,处于贫困、中等和富裕水平的农户分别为47户、47户和44户。根据受教育程度对农民进行分类,分别从文盲、读写、小学一、小学二周期教育水平对34、34、35和35名受访者进行访谈。雏鸡和公鸡性成熟年龄分别为5.64和5.25个月。蛋数、每窝蛋数和总蛋数/母鸡/年分别为3.04、12.78和38.53。本次调查的雏鸡孵化率和成活率分别为81.72%和38.85%。不同财富水平农户的性成熟、每窝卵数和孵化率差异显著(p 0.05)。总的来说,在Dawro区的Gena Bossa区,在农民的管理条件下,土鸡的生产和繁殖性能较低,这需要政府进一步改善,为农民组织有关疾病控制、鸡的饲养和饲养的培训,以提高生产和繁殖性能。关键词:农业生态,受教育程度,财富状况,生产和繁殖性能,土生鸡,肉鸡

In animal production, body weight is an important parameter for management, health and marketing decisions. This study is undertaken to determine the relationships between body weight and linear body measurements of guinea pigs. 120 guinea pigs (60 males and 60 females) were used. Body weight (BW), head-body length (HBL), chest circumference (CC), head circumference (HC), neck circumference (NC), left hind foot length (FL), and left ear length (EL) were the measured traits. The collected data were evaluated using multiple regression analysis. The obtained models of regression are : BW= - 397.374 + 10.817HBL + 16.440CC + 12.433NC - 19.039EL - 12.011FL + 12.458HC ; BW = - 560.601 + 4.531HBL + 21.649CC + 6.556NC -6.632EL – 2.086FL + 34.370HC ; BW = - 477.178 + 7.941HBL + 17.672CC + 8.758NC – 10.383EL – 1.951FL + 22.884HC, respectively for males, females and both sexes. In the regression model obtained for both sexes, the coefficients of HBL, CC and HC were significant (p < 0.01). The HC and CC coefficients for males and the CC and HC coefficients for females were also significant (p < 0.01). It was concluded that BW of guinea pigs was significantly influenced by CC, HBL, HC using multiple linear regression. Key words: Body weight, morphometric traits, equation, multiple regression, guinea pigs.
在动物生产中,体重是管理、健康和营销决策的重要参数。本研究旨在确定豚鼠体重与线性体测量之间的关系。共使用120只豚鼠(雄性60只,雌性60只)。体重(BW)、头身长(HBL)、胸围(CC)、头围(HC)、颈围(NC)、左后脚长(FL)、左耳长(EL)为测定性状。采用多元回归分析对收集的资料进行评价。得到的回归模型为:BW= - 397.374 + 10.817HBL + 16.440CC + 12.433NC - 19.039EL - 12.011FL + 12.458HC;Bw = - 560.601 + 4.531hbl + 21.649cc + 6.556nc -6.632 el - 2.086fl + 34.370hc;BW = - 477.178 + 7.941HBL + 17.672CC + 8.758NC - 10.383EL - 1.951FL + 22.884HC。在两性回归模型中,HBL、CC和HC的系数均显著(p < 0.01)。雄鼠的HC和CC系数、雌鼠的CC和HC系数均极显著(p < 0.01)。结果表明,CC、HBL、HC对豚鼠体重有显著影响。关键词:体重,形态性状,方程,多元回归,豚鼠

The study aims to determine the available beef and chicken edible offals and their prices in four major retail stores in Gaborone, Botswana. Traditionally, edible beef and chicken offal were available and sold in rural meat and informal markets around Gaborone, but recently upmarket retail stores of Gaborone sell these products. The study was done over a period of twelve months. Amongst the offals noted in the retail stores were ox tail, tongue, spleen, ox heel, kidneys, intestines, rumen, omasum, liver and ox heart for beef and feet, liver, gizzards, intestines, necks and kidneys for chicken. Offals were cheaper than the cheapest standard beef and chicken cuts being the chuck/brisket or stewing beef for beef and breast for chicken. Green beef offals were generally cheaper than red offals. The most expensive beef offal was ox tail at ~P60.00, and the cheapest offal was ox heel at ~P19.95 (USD1.00 ~ BWP11.00). For chicken, the gizzards were the most expensive at ~P49.45, with the necks being the cheapest at ~P26.59. Improved marketing and utilization of offals will reduce meat wastage. Meat processors will consequently generate more income, and assist with food security and nutrition at household level. Key words: Beef, chicken, edible offal products, pricing, retail chain stores.
该研究旨在确定博茨瓦纳哈博罗内四家主要零售商店中可用的牛肉和鸡肉可食用内脏及其价格。传统上,可食用的牛肉和鸡肉内脏可以在哈博罗内附近的农村肉类和非正式市场上买到,但最近哈博罗内的高档零售商店出售这些产品。这项研究持续了12个月。在零售商店中发现的内脏包括牛肉的牛尾、牛舌、牛脾、牛后跟、牛肾、牛肠、瘤胃、牛瓣、牛肝和牛心,以及鸡的肝、胗、肠、牛颈和牛肾。内脏比最便宜的标准牛肉和鸡肉切块便宜,比如牛头/胸肉或炖牛肉和鸡胸肉。绿牛肉内脏通常比红牛肉内脏便宜。最昂贵的牛尾为60比索,最便宜的牛后跟为19.95比索(1.00美元~ 11.00比索)。鸡胗最贵,约为49.45便士,鸡颈最便宜,约为26.59便士。改善内脏的销售和利用将减少肉类浪费。因此,肉类加工商将创造更多收入,并有助于家庭层面的粮食安全和营养。关键词:牛肉、鸡肉、食用内脏制品、定价、零售连锁店。

Aflatoxigenic fungi common to poultry feeds from Nigerian feed mills were investigated and their effects on broiler production were determined. Sixty two weeks old Abor-acre broilers were randomly divided into 5 treatment groups. Each treatment group had 3 replicates of 4 birds each. Birds in each treatment group were fed feed from one of five companies. Feed intake and body weights were determined. Blood samples were analyzed for hematological parameters. Feeds were analyzed for aflatoxin concentration using reverse phase High Performance Liquid Chromatography (HPLC). Aflatoxigenic fungi were identified by sequencing of the fungal ITS region. The major fungal contaminants identified in most of the feed samples were Aspergillus and Rhizopus species. Total aflatoxin content (AFB1+AFB2+AFG1 +AFG2) of the feeds ranged from <0.8 to 370±120 µg/kg. Feeds from three companies had aflatoxin concentrations above the European Community Regulatory Limits (ECRL, 20 μg/kg). Aflatoxin level was positively related to packed cell volume (PCV) and hemoglogin (Hb), although the relationship was not statistically significant. PCV and Hb were positively related. A negatively significant relationship was observed between the aflatoxin levels and WBC of the birds, feed intake and reduced body weight possibly because of the high aflatoxin concentrations in the feeds. The study has highlighted the effects of long storage time and poor processing of feed on intake and broiler performance. Key words: Aflatoxin, broilers, feed, hematology, fungi.
研究了尼日利亚饲料加工厂生产的家禽饲料中常见的致黄曲霉毒素真菌,并确定了它们对肉鸡生产的影响。选取62周龄1亩肉鸡,随机分为5个处理组。每个处理组设3个重复,每个重复4只鸡。每个实验组的鸟分别从五家公司中选择一家喂食饲料。测定采食量和体重。对血样进行血液学参数分析。采用反相高效液相色谱法测定饲料中黄曲霉毒素的浓度。通过真菌ITS区域的测序鉴定了黄曲霉毒素真菌。在大多数饲料样品中鉴定出的主要真菌污染物是曲霉和根霉。饲料中黄曲霉毒素总含量(AFB1+AFB2+AFG1 +AFG2)范围为<0.8 ~ 370±120µg/kg。3家公司饲料中黄曲霉毒素浓度均高于欧盟监管限值(ECRL, 20 μg/kg)。黄曲霉毒素水平与堆积细胞体积(PCV)和血红蛋白(Hb)呈正相关,但无统计学意义。PCV与Hb呈正相关。黄曲霉毒素水平与禽类白细胞计数、采食量和体重下降呈显著负相关,这可能与饲料中黄曲霉毒素含量高有关。本研究强调了饲料储存时间过长和处理不当对肉鸡采食量和生产性能的影响。关键词:黄曲霉毒素,肉鸡,饲料,血液学,真菌

The study has highlighted the effects of long storage time and poor processing of feed on intake and broiler performance. \u0000 \u0000 Key words: Aflatoxin, broilers, feed, hematology, fungi.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82900074","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}

Exotic chicken breeds were promoted and disseminated in the rural and peri-urban parts of Ethiopia, to improve the productivity of the poultry to increase the income of farmers. The study was conducted to explore the factors affecting adoption of exotic chicken breed in Tselemti and Tahtay Koraro districts of North Western zone of Tigray region, Ethiopia. A multi-stage random sampling technique was followed to select 264 respondents from the six randomly selected Kebelles of the two districts. Primary data were collected using semi-structured interview questionnaire from the respondents. Descriptive statistics and binary logistic regression model were used for analyzing the collected quantitative data. The results of the logit model indicates that family size, sex of the household head, education status of the household head, livestock holding size, extension contact, availability of exotic chicken breed, distance to the nearest market and availability of training on poultry production could play a significant role on the probability of exotic poultry breed adoption. Thus, the dissemination of different exotic chicken breeds needs to be supported with giving training to the farmers before intervention of the technology, extension backup on how to manage and awareness creation on the benefits of exotic chicken breed and giving focus in delivering and making available the chicks of exotic poultry breeds to the farmers. Key words: Adoption, exotic poultry breed, factors, binary logit model.
在埃塞俄比亚的农村和城郊地区推广和传播了外来鸡品种,以提高家禽的生产力,增加农民的收入。本研究旨在探讨埃塞俄比亚提格雷地区西北地区Tselemti和Tahtay Koraro地区外来鸡品种饲养的影响因素。采用多阶段随机抽样的方法,从两个区随机抽取的6个小客栈中抽取264名回答者。主要数据采用半结构化访谈问卷收集。采用描述性统计和二元logistic回归模型对收集到的定量数据进行分析。logit模型的结果表明,家庭规模、户主性别、户主受教育程度、牲畜饲养规模、推广联系、外来鸡品种的可得性、到最近市场的距离和家禽生产培训的可得性对外来家禽品种的采用概率有显著影响。因此,需要在技术干预之前对农民进行培训,在如何管理和提高对外来鸡品种效益的认识方面提供支持,并重点向农民提供和提供外来鸡品种的小鸡。关键词:收养,外来家禽品种,影响因素,二元logit模型。

The study aimed to determine pathological conditions across two seasons, leading to condemnations of beef edible red offals in Kgatleng District, Botswana. Offals are valued in communities of Botswana. Data from slaughter facilities was evaluated for dry/winter and wet/summer seasons. Financial losses were also determined. 7405 cattle were processed in the two seasons, with 4005 cattle slaughtered in the dry season and 3400 in the wet season. Of the slaughtered cattle, 55.2% (2209) of the dry season and 45% (1531) of the wet seasonhad some forms of pathological conditions that led to condemnations of the offals. Lungs were highly condemned at 26.2% in the wet season and 32.7% during the dry season, followed by livers at 16.2 and 18.4% in the wet and dry seasons, respectively. Emphysema led to a condemnation rate of lungs at 20% and 17% for the dry and wet seasons, respectively. The least condemned offals were the spleen at 2.3% (wet season) and 2.1% (dry season), followed by the kidneys at 0.3% (wet season) and 2% (dry season). Financially, the dry season losses were relatively higher at BWP62 950.55 compared to the wet season at BWP43 863.95. Management strategies should be put in place to avail offals to consumers. Key words: Beef, edible red offals, pathological conditions, wet and dry seasons.
该研究旨在确定两个季节的病理情况,导致博茨瓦纳kgateng地区对牛肉食用红色内脏的谴责。动物内脏在博茨瓦纳的社区是很有价值的。对屠宰设施的数据在干/冬季和湿/夏季进行了评估。经济损失也被确定。两季加工牛7405头,干季屠宰4005头,湿季屠宰3400头。在被屠宰的牛中,干季的55.2%(2209头)和湿季的45%(1531头)有某种形式的病理状况,导致了对内脏的谴责。肺在湿季和干季分别占26.2%和32.7%,其次是肝脏,湿季和干季分别占16.2%和18.4%。肺气肿导致肺的谴责率在干季和湿季分别为20%和17%。最不受谴责的内脏是脾脏,分别为2.3%(雨季)和2.1%(旱季),其次是肾脏,分别为0.3%(雨季)和2%(旱季)。从财务上看,旱季损失为BWP62 950.55,旱季损失为BWP43 863.95。管理策略应该到位,以使消费者受益。关键词:牛肉,食用红内脏,病理情况,干湿季节。
