The aim of the survey was to assess artificial insemination (AI) service delivery system and identify the challenges and opportunities of AI service in cattle production in Western Zone of Tigray Region, Ethiopia. Twenty Kebeles (lowest administrative units) and 353 respondents were purposively involved in face-to-face interview. Data analysis was performed using SPSS and mainly summarized by frequency and percentages. Chi-square test was the statistical method used to test proportions of variables. There was statistically significant (P<0.05) differences in AI service interruptions in both regular working hours and weekends and holiday hours. AI service interruption was a critical challenge in regular working days and in weekends and holidays. This is because 73% of the respondents reported that AI service was interrupted in Monday through Friday and 75% of the respondents also reported that Artificial Insemination Technicians (AITs) were not available to deliver AI service in weekends and holidays. Above half (63%) of the small scale farmers reported that AITs were very poor. Most of the very poor AITs were in midland (48%) and lowland (36%) agro-ecologies compared to the AITs in highland (16%) agro-ecology. Mobile AI service delivery system through motor bikes was the most common AI service delivery system used. The major challenges of AI service in order of their importance were lack of community awareness, poor animal management, unskilled AITs and inadequacy of AITs. The government and NGOs should solve the current challenges of AI service. The current approach and system of AI delivery should be restructured. Adequate numbers of skilled manpower should be assigned based on the standard numbers of breedable cows per AI center or per AIT. Moreover, agro-ecology based human management system and infrastructure development should be adequately addressed.  Key words: Communication means, AI service interruption, distance between homestead and AI service center, AI service delivery system, agro-ecology.
该调查的目的是评估人工授精(AI)服务提供系统,并确定人工授精服务在埃塞俄比亚提格雷地区西部地区牛生产中的挑战和机遇。有目的地对20个最低行政单位和353名受访者进行面对面访谈。数据分析采用SPSS软件,主要以频次和百分比进行汇总。卡方检验是检验变量比例的统计方法。人工智能服务中断在正常工作时间和周末假日时间的差异有统计学意义(P<0.05)。在正常工作日和周末、节假日,人工智能服务中断是一个严峻的挑战。这是因为73%的受访者表示,人工智能服务在周一至周五中断,75%的受访者还表示,人工授精技术人员(ait)在周末和节假日无法提供人工智能服务。超过一半(63%)的小农报告说,ait非常贫穷。与高地农业生态系统的农业生态系统(16%)相比,大部分非常差的农业生态系统位于中部(48%)和低地(36%)。通过摩托车的移动人工智能服务传递系统是使用最多的人工智能服务传递系统。人工智能服务的主要挑战是缺乏社区意识、动物管理不善、人工智能人员不熟练和人工智能人员不足。政府和非政府组织应该解决当前人工智能服务的挑战。目前的人工智能交付方法和系统应该进行重组。应根据每个人工智能中心或每个人工智能部门可繁殖奶牛的标准数量分配足够数量的熟练人力。此外,应充分解决以农业生态为基础的人力管理系统和基础设施建设问题。关键词:通信手段、人工智能服务中断、宅基地与人工智能服务中心距离、人工智能服务提供系统、农业生态

Cattle crossbreeding for sustainable milk production in the tropics 热带地区可持续产奶的牛杂交
Pub Date : 2020-10-31 DOI: 10.5897/ijlp2020.0717

Crossbreeding has been used to improve milk production performance of local cattle in the tropics. Crossbreeding exploits additive and non-additive allele gene effects leading to improvements in lactation length, decrease in calving interval, higher milk yields and early age of calving of cows and potentially increasing producer incomes. Varying levels of success have been reported for various crossbreeding programmes and the objective of the current review was to document the key challenges, best practices, lessons learnt and to propose sustainable interventions for future initiatives. Although crossbreeding has had some impacts on smallholder dairy production in the tropics, a number of bottlenecks affect its smooth implementation including inadequate funding, inappropriate policies, low participation of farmers and genotype and environment mismatches. The availability of large base of adapted local cattle genetic resources, innovative state of the art breeding technologies and goodwill of governments to make favourable policies and increase budgetary allocations for the livestock sector offer some prospects for crossbreeding for a sustainable dairy industry. Provision of the required infrastructure for improved management of crossbred dairy cattle including feeding and health care, access to markets, training of stakeholders, a well-trained and motivated local extension service personnel are recommended to help achieve this objective. Key words: Artificial insemination, genotype-environment interaction, local breeds.
杂交育种已被用于提高热带地区当地牛的产奶性能。杂交利用加性和非加性等位基因效应,可延长泌乳时间,缩短产犊间隔,提高产奶量,缩短产犊年龄,并有可能增加生产者收入。据报道,各种杂交计划取得了不同程度的成功,本次审查的目的是记录主要挑战、最佳做法、吸取的教训,并为未来的举措提出可持续的干预措施。尽管杂交对热带地区的小农乳制品生产产生了一些影响,但一些瓶颈影响了其顺利实施,包括资金不足、政策不适当、农民参与度低以及基因型和环境不匹配。可获得的大量适应的地方牛遗传资源、创新的最先进育种技术以及政府制定有利政策和增加对畜牧业的预算拨款的善意,为可持续乳制品行业的杂交育种提供了一些前景。建议提供必要的基础设施,以改善杂交奶牛的管理,包括喂养和保健、进入市场、培训利益攸关方、训练有素和积极进取的当地推广服务人员,以帮助实现这一目标。关键词:人工授精,基因型-环境互作,地方品种

To document current rabbit management practices in Kiambu County, a survey using structured questionnaire was undertaken in 45 farms identified using snow ball sampling technique. Data collected were subjected to descriptive statistics. Findings revealed that the majority of the respondents (57.8%) kept more than 10 does while the most prevalent breed was New Zealand White (82.2%). The main purpose of keeping rabbits for the majority (54%) of the farmers was income generation. Rabbit keepers depended on locally available feed resources with the majority (82.2%) feeding a mixture of forages and concentrate. The majority of respondents (71.1%) weaned the kits at 8 weeks of age while does were rebred at 9 weeks after kindling on 68.9% of the farms. Treatment of sick rabbits was done majorly by the farmers themselves (60.5%). Constraints identified included high cost of feeds (88.9%), diseases (84.4%) and lack of markets for rabbits and rabbit products (71.1%). This study concluded that rabbit farming in Kiambu County is practiced on small scale characterized by limited resource allocation and small flock sizes which may not support a sustainable off-take rate to meet the intended purpose of income generation.  Key words: Rabbits, feed resources, health, Kenya.
为了记录Kiambu县目前的兔子管理做法,使用结构化问卷对45个使用雪球抽样技术确定的养殖场进行了调查。收集的数据进行描述性统计。调查结果显示,大多数受访者(57.8%)养了10只以上的狗,而最常见的品种是新西兰白狗(82.2%)。大多数(54%)农民养兔的主要目的是创收。养兔人依赖当地可获得的饲料资源,大多数(82.2%)饲养饲料混合饲料和精料。大多数应答者(71.1%)在8周龄断奶,68.9%的养殖场在点燃后9周龄繁殖。病兔的治疗主要由养殖户自己完成(60.5%)。确定的制约因素包括饲料成本高(88.9%)、疾病(84.4%)和缺乏兔子和兔子产品市场(71.1%)。本研究的结论是,Kiambu县的养兔业规模较小,资源分配有限,畜群规模小,可能无法支持可持续的采收率,以满足预期的创收目的。关键词:家兔,饲料资源,卫生,肯尼亚

Poor animal health is reported as one of the major constraints of goat production leading to mortality in pastoral areas like Karamoja Sub-Region in Eastern Uganda. Based in Napak District, this study was aimed at gaining an understanding of the role of proper health management in reducing goat mortality in Kraals. Through convenience sampling, 312 pastoralists out of 388 who own animals in community kraals were reached. The study was carried out using mixed methods approach through structured interviews and focus group discussions to collect both primary and secondary data. The health management index (HMI) as a measure of proper goat health management was constructed using seven routine farm practices (Vaccination, Deworming, Use of Antibiotic, Spraying, Isolation of sick animals, Sanitation and Hygiene and Navel Cord Disinfection). Multivariable regression was conducted using STATA (12) software. The first regression was conducted to find out which socio-economic factors have influence on HMI. It was established that accessibility to training and membership to social groups improve HMP while involvement in other occupation has a negative influence. A second regression was conducted to ascertain if HMI scores affect goat mortality levels. The results revealed a negative and significant influence, implying that an improvement in HMP leads to a reduction in mortality. Enhancing mechanisms which favor practical training and social group formation in form of technology intervention platforms can enhance HMP which will ultimately reduce goat mortality. Key words: Socio-economic factors, goat health management index, Karamoja, goat, multivariable regression.
据报告,在乌干达东部的卡拉莫贾分区域等牧区,牲畜健康状况不佳是山羊生产的主要制约因素之一,导致山羊死亡。这项研究以纳帕克县为基地,旨在了解适当的健康管理在降低Kraals山羊死亡率方面的作用。通过方便抽样,访问了388名在社区牧区拥有牲畜的牧民中的312名。本研究采用混合方法,通过结构化访谈和焦点小组讨论来收集第一手和第二手数据。采用预防接种、驱虫、抗生素使用、喷洒、病畜隔离、卫生卫生和脐带消毒等7项常规措施,构建了山羊健康管理指标(HMI)。采用STATA(12)软件进行多变量回归。第一次回归是为了找出社会经济因素对HMI的影响。可以确定的是,获得培训和加入社会团体的机会可以改善HMP,而参与其他职业则会产生负面影响。进行第二次回归以确定HMI评分是否影响山羊死亡率水平。结果显示了负的和显著的影响,这意味着HMP的改善导致死亡率的降低。以技术干预平台的形式加强有利于实践训练和社会群体形成的机制,可以提高HMP,最终降低山羊死亡率。关键词:社会经济因素;山羊健康管理指数;卡拉莫贾山羊;

In Zimbabwe, at least 97% of the national goat herd is owned by smallholder indigenous farmers. The farmers rarely breed the goats for commercial purposes despite the fact that the country has potential to export goat products. Common breeds in Zimbabwe include the Matabele goats, Mashona goats, Boer goats and the Kalahari goats. With this diversity of the goats’ population, there is need to move from subsistence to commercial production. The drought prone Inyati community is likely to benefit in terms of nutrition and economic security from the goat business. Goats are a rich source of meat (chevon), milk and skins products. While there is a market for goat meat locally, communities can exploit better opportunities in the Southern Africa region such as South Africa as well as beyond the continent, to the Middle East. Goat farming is a viable enterprise and farmers in Inyati district can prosper relying on their indigenous environment. The focus of the study is Inyati community, particularly the smallholder indigenous goat farmers in the area. A purposive sample of 19 goat keeping households was selected on the basis of their flock size from 8 villages under the Inyati community. Data were collected using semi-structured group interviews coupled with personal interviews involving three to four households per village as well as observations. Extension workers, as representatives on the ground were used in the collection of information from communities. Findings of the study revealed that there were management challenges in the rearing and marketing of goats by indigenous farmers. Among other challenges were factors such as high kid mortality and lack of good management practices among farmers, lack of information on the emerging commercial goat production system, economic viability, prospects and constraints of commercial goat farming in the country. Recommended for the study was information on marketing system for goats and their products, and the mechanisms stretch from village level to markets, both locally and abroad. The study came up with a model which promotes the sharing of information between commercial goat farmers in the country. The information shared includes quality of animal’s breeds (germplasm) which are critical for the strengthening of indigenous farmer goat enterprise in Zimbabwe. Key words: Goat flock, goat breed, goat breeding, indigenous, small holder farmers.
在津巴布韦,至少97%的全国山羊群归当地小农所有。尽管该国有出口山羊产品的潜力,但农民很少出于商业目的饲养山羊。津巴布韦常见的品种包括马塔贝尔山羊、马绍纳山羊、布尔山羊和喀拉哈里山羊。由于山羊种群的多样性,有必要从自给生产转向商业生产。易受干旱影响的Inyati社区可能会从山羊生意中获得营养和经济保障。山羊是肉、奶和兽皮制品的丰富来源。虽然当地有山羊肉市场,但社区可以在南非等南部非洲地区以及非洲大陆以外的中东地区利用更好的机会。山羊养殖是一个可行的企业,Inyati地区的农民可以依靠他们的本土环境致富。研究的重点是Inyati社区,特别是该地区的小农户。从Inyati社区所属的8个村庄中选取19户山羊养殖户,根据其羊群规模进行目的抽样。数据的收集采用半结构化的小组访谈和每个村庄三到四个家庭的个人访谈以及观察。作为实地代表的推广工作人员被用于从社区收集信息。研究结果表明,土著农民在饲养和销售山羊方面存在管理挑战。其他挑战包括儿童死亡率高、农民缺乏良好的管理做法、缺乏关于新兴的商业山羊生产系统的信息、该国商业山羊养殖的经济可行性、前景和限制等因素。这项研究建议提供关于山羊及其产品销售系统的资料,以及从村庄一级到当地和国外市场的机制。这项研究提出了一个模型,可以促进该国商业山羊养殖户之间的信息共享。共享的信息包括动物品种(种质)的质量,这对加强津巴布韦当地农民山羊企业至关重要。关键词:羊群,山羊品种,山羊育种,土著,小农。

The last of us? An online survey among German farm veterinarians about the future of veterinary training, livestock farming and the profession in general 我们最后的人?一项针对德国农场兽医的在线调查,调查内容涉及兽医培训、畜牧业和整个职业的未来
Pub Date : 2020-06-30 DOI: 10.5897/IJLP2020.0697
Christian Dürnberger
This online survey investigated how German farm veterinarians perceive the future of their profession. According to the participants, the following topics should play a greater role in veterinary training: Economics, herd health management, practical education, agricultural knowledge and animal welfare issues. The top answer indicates that knowledge about entrepreneurship is seen as a crucial competence of veterinarians. In regard to urgently needed changes in livestock farming, the participants recommend a general economic restructuring, a more fact-based public and political debate, an improved control system, improved training of farmers with a focus on animal welfare and a general critical questioning of performance optimisation. While the common literature focuses on reasons for distress, the survey identified factors for job satisfaction: German farm veterinarians recommend their job because of the variety of veterinary work, the contact with animal owners, the contact with animals, economic security, the importance of the work because it is about producing food and the possibility to work outdoors. At the same time, the survey identified a general dark mood when it comes to the future of the profession and livestock farming in general. Veterinarians see themselves as part of a world that is in decline. Key words: Online survey, German farm veterinarians, veterinary ethics, food production, veterinary curriculum, animal welfare, veterinary education.
这项在线调查调查了德国农场兽医如何看待他们职业的未来。与会者认为,以下主题应该在兽医培训中发挥更大的作用:经济学、畜群健康管理、实践教育、农业知识和动物福利问题。最上面的答案表明,创业知识被视为兽医的关键能力。关于牲畜养殖迫切需要的变革,与会者建议进行全面的经济结构调整,进行更加基于事实的公共和政治辩论,改进控制系统,改进对农民的培训,重点关注动物福利,并对绩效优化进行普遍的批判性质疑。虽然一般文献关注的是痛苦的原因,但这项调查确定了工作满意度的因素:德国农场兽医推荐他们的工作是因为兽医工作的多样性,与动物主人的接触,与动物的接触,经济安全,工作的重要性,因为它是关于生产食物的,以及在户外工作的可能性。与此同时,该调查发现,当涉及到该行业和畜牧业的未来时,人们普遍感到悲观。兽医们把自己看作是这个正在衰落的世界的一部分。关键词:在线调查,德国农场兽医,兽医伦理,食品生产,兽医课程,动物福利,兽医教育。

Veterinarians see themselves as part of a world that is in decline. \u0000 \u0000 Key words: Online survey, German farm veterinarians, veterinary ethics, food production, veterinary curriculum, animal welfare, veterinary education.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83676766","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}

This study was aimed to evaluate the effect of flushing on the reproductive and body weight change on Abergelle breed does. The study indicated that a mix of 300 or 450 g wheat bran (WB) with 50 g noug seed cake (NSC) flushed per day improved the does’ conception rate (70 to 80%) and kidding rate (70%); while does flushed with low concentrate level (150 g WB plus 50 g NSC) or those not flushed had poor and reduced conception and kidding rate almost by half from the flushed ones. However, the high concentrate level is not strategic to reduce abortion rate. Does flushed with high concentrate level (300 and 450 g WB mix with 50 g NSC) were significantly (p<0.05) better in body weight at kidding (18.52 kg) and postpartum weight (19.48 kg) than does flushed with low concentrate level (16.44 and 17.70 kg, respectively). As the concentrate levels supplementation of their dam increased, birth weight of kids increased (1.73 to 2.36 kg). Therefore, the conception rate, postpartum weight, kid production of Abergelle goat can improve by flushing with 300 g WB and 50 g NSC concentrated feed. However, its effect on the reduction of abortion rate is not promising. Further study is needed on the abortion problem. Key words: Abortion rate, birth weight, body weight, conception rate, concentrated feed, goat, kidding rate, supplementation.
本研究旨在评价冲红对阿贝犬繁殖和体重变化的影响。研究表明,每天冲洗300或450克麦麸(WB)和50克足够的种子饼(NSC)的混合物可提高受孕率(70 - 80%)和开胎率(70%);而低浓缩水平(150克WB加50克NSC)冲洗的母鼠或未冲洗的母鼠的受孕率和开玩笑率较冲洗过的母鼠低,几乎降低了一半。然而,高浓缩水平并不是降低流产率的策略。高精料水平(300和450 g WB混合50 g NSC)冲犊犊的孕前体重(18.52 kg)和产后体重(19.48 kg)显著优于低精料水平(16.44和17.70 kg)冲犊犊。随着精料添加量的增加,幼仔出生体重增加(1.73 ~ 2.36 kg)。因此,300 g WB和50 g NSC浓缩饲料可提高阿贝格山羊受孕率、产后体重和产仔量。然而,其对降低堕胎率的效果并不乐观。堕胎问题需要进一步研究。关键词:流产率,出生体重,体重,受孕率,浓缩饲料,山羊,开玩笑率,添加。

Poultry farming is an important sector of the Beninese agriculture. But this sector is facing economic difficulties. The aim of this study is to evaluate the effects of Moringa oleifera powder and soybean meal on zootechnical parameters in the ISA Brown pullet. For this purpose, the experiment was carried out on a total of 250 day-old chicks with an initial average weight of 40 ± 1 g. Among these chicks, 25 subjects were used for the digestibility test and the rest were grouped into cinq (05) batches of 45 chicks fed with different rations. The test lasted 56 days. The apparent digestibility of the dry matter varied significantly from 50.0 ± 9.18 to 50.42 ± 16.11 at the 5% threshold between the different batches. Feed consumption of chicks of the different experimental batches did not show any significant variation, while for the feed conversion rate, weight gain and average daily gain, most averages vary significantly between batches and weeks. It brings out that M. oleifera powder improves the feed conversion and growth rates of ISA Brown pullets fed with a feed containing M. oleifera powder at different incorporation rates. Key words: Moringa oleifera, soybean, ISA Brown laying hens, zootechnical parameters.
家禽养殖是贝宁农业的重要组成部分。但该行业正面临经济困难。本试验旨在探讨辣木粉和豆粕对ISA褐仔鸡动物技术参数的影响。为此,选取初始平均体重为40±1 g的250只日龄雏鸡进行试验。选取25只雏鸡进行消化率试验,其余雏鸡随机分为5(05)批次,每批次45只,饲喂不同的日粮。试验持续56 d。在5%的阈值下,不同批次的干物质表观消化率在50.0±9.18 ~ 50.42±16.11之间差异显著。不同试验批次雏鸡的采食量变化不显著,而饲料转化率、增重和平均日增重在批次和周间差异显著。结果表明,在不同添加量的油棕粉饲料中,油棕粉能提高褐仔鸡的饲料转化率和生长率。关键词:辣木,大豆,ISA褐蛋鸡,动物技术参数

The study was conducted in Amhara, Oromia, Southern Nations Nationalities and Peoples and Tigray regions of the country to provide information on the performance of Artificial Insemination (AI) service delivery system, its seasonality and effectiveness. Semi-structured questionnaire was prepared to interview AI technicians (on their performance and related issues) and farmers (about the outcome of AI services). Data on field performance were received directly from AI technicians using a pre-restructured reporting format. A follow-up calving survey for AI services were provided to farmers was conducted in March 2019 to know the outcome of insemination services provided to farmers. Peak season falls from August to December when AI technicians on average perform 6.7 inseminations per day. January, February, June, and July were categorized as regular season with daily average insemination of 3.8. March, April, and May are off-season with an average of only 2.2 inseminations per day. The seasonal variation is mainly associated with availability of feed. Field level actual performance data showed significant difference (P 0.05) with mean SPC of 2.13. About 2.6 SPC obtained from a follow-up survey conducted with farmers who received AI service in a specified period. About 62% conception rate and 82% calving rates are obtained in this study. Key words:  Cattle, farmers, performance, technicians, semen.

This study was conducted to evaluate the production and reproduction performance of chicken breed under semi-scavenging system of Seka Chekorsa and Omo Nada districts of Jimma Zone. A total of 800 day old chicks were obtained from Debre Zeit Agricultural Research center. 50 day old chicks were distributed with hay box brooder, and the experiment was arranged in a nested design. The result of the current study indicated that male chickens of both breeds in this study reached sexual maturity and slaughter weight within four months in both districts and mature body weights of 1831.25 and 1569.18 g at Seka and 1615.00 and 1586.25g in Omo Nada, respectively for Lohmann dual and Dominant red barred. Although there was no statistically significant difference between the two breeds, Lohmann dual breeds attained age at first egg within 148 days and Dominant red barred (162.25 days) breeds in Seka Chekorsa and 157.50 and 160.25 days, respectively for lohmann and Dominant red barred in Omo Nada district. In general, the current study indicated good performance of Lohmann dual breeds while it needs further study to conclude number of eggs per clutch, number of eggs per hen per year and hatchability for both breeds in both study districts. So this study might be good to consider in the future in other areas. Key words: Dual purpose breed, on farm evaluation, semi-scavenging, Omo Nada, Seka Chekorsa.
本试验对吉马地区塞卡切科尔萨区和奥莫那达区半清道夫制度下鸡种的生产和繁殖性能进行了评价。从Debre Zeit农业研究中心共获得800只日龄雏鸡。50日龄雏鸡配干草箱育雏机,试验采用巢式设计。本研究结果表明,本研究两个品种的雄鸡在4个月内均达到性成熟和屠宰体重,Seka的成熟体重分别为1831.25 g和1569.18 g, Omo Nada的成熟体重分别为1615.00 g和1586.25g。虽然两种品种间差异无统计学意义,但Seka Chekorsa地区罗曼双种的首蛋龄为148 d,奥莫纳达地区罗曼双种的首蛋龄为162.25 d,奥莫纳达地区罗曼双种的首蛋龄为157.50 d,奥莫纳达地区罗曼双种的首蛋龄为160.25 d。总的来说,目前的研究表明罗曼双品种的生产性能良好,但需要进一步研究得出两个研究地区两个品种的每窝蛋数、每年每只母鸡的蛋数和孵化率。因此,这项研究可能是很好的考虑在其他领域的未来。关键词:双用途品种,田间评价,半食性,奥莫那达,塞卡切科尔萨
