A total of 161 apparently healthy male and female, grower and adult local chickens were sampled from Live bird Markets (LMB) in four Agricultural zones of the State; Gwadabawa, Tambuwal, Isa and Sokoto. They were screened for antibodies to infectious bronchitis virus using Enzyme linked Immuno Sorbent Assay (ELISA). The results obtained showed that the overall prevalence for the State was 89%, the seroprevalence was 88.89% in males and 89.00 % in females, 91.50% in adults and 70.00% in growers sampled. No significant difference was obtained between male and female chickens tested (χ2 >0.05) but significant difference was obtained in adult and grower chickens (χ2 < 0.05). No routine vaccination against infectious bronchitis is usually carried out in the area; the high prevalence observed may suggest natural infection. Efforts should be made to determine strains of IBV circulating in the study area so as to enable the choice of appropriate vaccine.
从该州四个农业区的活禽市场(LMB)抽取了161只明显健康的雄性和雌性、养殖和成年地方鸡;瓜达巴瓦,坦布瓦尔,伊萨和索科托。使用酶联免疫吸附试验(ELISA)筛选传染性支气管炎病毒抗体。结果表明,我省总流行率为89%,其中男性为88.89%,女性为89.00%,成人为91.50%,种植户为70.00%。公、母雏鸡间差异不显著(χ2 >0.05),成鸡与生长鸡间差异显著(χ2 < 0.05)。该地区通常不进行预防传染性支气管炎的常规疫苗接种;观察到的高流行率可能提示自然感染。应努力确定在研究地区流行的IBV菌株,以便能够选择适当的疫苗。

Indigenous or village or local  chickens  are  an important  source of animal protein in the form of meat and eggs, contribute to rural food security and are an important avenue for woman empowerment as indigenous chickens in poor communities are mostly owned by women in Sub Saharan Africa. There are many factors that affect dressing percentage, carcass traits and meat quality properties in indigenous chicken, such as genetics, nutrition, environment, and additives, however, genetics is one of the most important factors. The knowledge on variability of genotype of indigenous chicken accompanied by manipulation of their production system will  translate into a specific desirable  dressing percentage, carcass characteristic and meat quality properties, which is paramount criteria for consumers when it comes to making purchasing decisions. Therefore, using different indigenous chicken genotypes, the producer may sort to employ management practices which furnish with acceptable dressing percentage, carcass and meat quality properties which do not compromise and maintain health in consumers. However, very few studies have been reported on the utilization of different indigenous chickens genotypes in improvement of carcass and meat quality properties. Feeding systems, slaughter age and rearing systems are some of the environmental factors which have been examined in indigenous chickens to determine their influence on carcass and meat quality properties. It has been noted that varying the discrete variables such as genotype and sex had significant differences in the nature of corresponding carcass and meat quality properties in indigenous chickens. Variations in the genetic make-up and sexual dimorphism in indigenous chickens accounted for the observed differences in dressing percentage and carcass characteristic. The preceding review gives some insight on the influence of genotype and sex on dressing percentage, carcass parameters and meat quality properties in indigenous chickens.
土著或村庄或当地鸡是肉和蛋形式的动物蛋白的重要来源,有助于农村粮食安全,也是增强妇女权能的重要途径,因为撒哈拉以南非洲贫困社区的土著鸡大多由妇女拥有。影响土鸡屠宰率、胴体性状和肉品质的因素很多,如遗传、营养、环境和添加剂等,其中遗传是最重要的因素之一。对本地鸡基因型变异性的了解,加上对其生产系统的操纵,将转化为特定的理想屠宰率、胴体特性和肉质特性,这是消费者做出购买决定时最重要的标准。因此,使用不同的本地鸡基因型,生产者可以采取管理措施,提供可接受的屠宰率、胴体和肉品质,而不损害和保持消费者的健康。然而,利用不同的地方鸡基因型来改善胴体和肉品质的研究报道很少。饲养系统、屠宰年龄和饲养系统是一些环境因素,已在土鸡中进行了检查,以确定它们对胴体和肉质特性的影响。研究发现,不同的基因型和性别等离散变量对土鸡的胴体性质和肉质特性有显著影响。土鸡的基因组成和两性二态性的差异是观察到的屠宰率和胴体特性差异的原因。本文综述了基因型和性别对土鸡屠宰率、胴体参数和肉品质的影响。

This review article looks at some major factors that influence carcass composition in goats. The resultant carcass composition of various animal species differs considerably depending on several environmental factors and management practices. These several factors which are within control of animal producers may be manipulated to achieve desirable effects in carcass composition. Some of the factors which have been implicated to cause considerable variation in carcass composition include genetic, nutrition, age at slaughter, sex of animal and weight of animal. Carcass composition  differ among animal species, even within more similar or homogenous groups such as small ruminants and differences are mainly species dependent.
本文综述了影响山羊胴体组成的一些主要因素。不同动物物种的最终胴体组成因若干环境因素和管理做法而有很大差异。这几个在动物生产者控制范围内的因素可以加以控制,以在胴体组成方面达到理想的效果。导致胴体组成显著差异的一些因素包括遗传、营养、屠宰年龄、动物性别和动物体重。动物物种之间的胴体组成不同,即使在更相似或同质的群体中,如小反刍动物,差异主要取决于物种。

Focusing on livestock improvement strategies that enhance adaptive and coping mechanisms in the context of climate change in southern Africa 重点关注在南部非洲气候变化背景下加强适应和应对机制的牲畜改良战略
Pub Date : 2015-06-29 DOI: 10.14196/SJAS.V4I6.1874

Climate change and variability is among the first and crucial limiting factors of sustainable livestock production in southern Africa. This is on the background that southern Africa is one of the most vulnerable sub regions to climate change and climate variability, a situation aggravated by the interaction of the multiple stresses that occur at various levels and the agricultural systems’ low adaptive capacity. However, it is undisputable that many poor resource livestock farmers who are the majority in southern Africa are wholly or partially dependent on livestock for their livelihood, and livestock keepers will need to adapt to climate change for their survival. This development has spurred the need for creation and implementation of livestock improvement strategies aimed at overcoming the negative effect of climate change on livestock production. In addition, climate change induced environmental stressors will further accentuate heat, disease and water stress-related problems.  The review explores some of the likely impacts of climate change on livestock production and discusses measures to react to the expected changes in climate through livestock improvement. This is followed by a discussion of how climate change may alter the approach to genetic improvement. The report then analyses the specific issue of selection and crossbreeding systems and their implication for livestock improvement. It is suggested that the focus on livestock improvement strategies will need to take into account the alleviation of heat and water stress in the context of semi arid  livestock production systems. Livestock improvement based on livestock adaptive strategies and coping mechanisms  in the context of climate change are critical in this context. This is a result of the understanding that livestock productivity decline has become a problematic issue in southern Africa, particularly due to the long term effect of climate change. Climate change has risen to become one of the most challenging issues confronting the sub region through decline of livestock productivity. In order to lessen the extent of livestock vulnerability to climate change livestock improvement strategies should take into cognizance of enhancing adaptive  and coping mechanisms  in livestock production. In recognition of this threat to the sub region, this paper  further discusses some of the pertinent issues which proffers possible solutions aimed at aiding appropriate livestock improvement in the context of climate change. Accordingly, developing new and innovative livestock improvement strategies to understand the relationship between climate change induced stressful environment and animal productivity, while highlighting livestock improvement strategies and livestock traits to target. Promoting local animal genetic resources will be part of the mitigation strategy.
气候变化和变异是南部非洲可持续畜牧业生产的首要和关键限制因素之一。其背景是,南部非洲是最易受气候变化和气候变率影响的次区域之一,而发生在各个层面的多重压力和农业系统的低适应能力的相互作用加剧了这种情况。然而,无可争议的是,在南部非洲占多数的许多资源贫乏的畜牧农民全部或部分地依靠牲畜为生,牲畜饲养者将需要适应气候变化才能生存。这一发展促使有必要制定和实施旨在克服气候变化对畜牧业生产的负面影响的牲畜改良战略。此外,气候变化引起的环境压力因素将进一步加剧与热、疾病和水压力有关的问题。本文探讨了气候变化对畜牧业生产的一些可能影响,并讨论了通过畜牧业改良来应对预期气候变化的措施。接下来是关于气候变化如何改变基因改良方法的讨论。然后,报告分析了选择和杂交系统的具体问题及其对牲畜改良的意义。有人建议,家畜改良战略的重点将需要考虑到在半干旱牲畜生产系统的背景下减轻热量和水的压力。在此背景下,基于牲畜适应策略和应对机制的牲畜改良在气候变化背景下至关重要。这是因为人们认识到,特别是由于气候变化的长期影响,牲畜生产力下降已成为南部非洲的一个问题。气候变化导致畜牧业生产力下降,已成为该次区域面临的最具挑战性的问题之一。为了减轻畜牧业对气候变化的脆弱性,畜牧业改良战略应考虑到加强畜牧业生产中的适应和应对机制。认识到这一对次区域的威胁,本文进一步讨论了一些相关问题,提供了在气候变化背景下帮助适当改善牲畜的可能解决方案。因此,制定新的和创新的牲畜改良战略,以了解气候变化引起的应激环境与动物生产力之间的关系,同时突出牲畜改良战略和牲畜性状的目标。促进当地动物遗传资源将是缓解战略的一部分。

Rapidly growing morbidity and mortality due to heart disease is a great concerned for scientist. Among the etiology of atherosclerosis, dyslipidemia is a major risk factor. Garlic has active ingredients of allium sativum used in high blood pressure management. Garlic has been used as a therapeutic agent for many illnesses such as hypertension, dyslipidemia and cardiovascular diseases. Evidence from various studies and clinical trials proved the efficacy of garlic to reduce lipid level.However, some contradictory results are also reported. This review was undertaken to assess the role of garlic therapy in dyslipidemia. Major databases including Google, PubMed, MEDLINE, and Cochrane library view were used for literature search. Clinical trials conducted on humans assessing role of garlic therapy in dyslipidemia and the possible mechanisms responsible for such therapeutic actions were assessed. Several trials and meta-analyses have suggested positive effect of garlic on total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL) and triglycerides (TG). This review on garlic therapy in dyslipidemia suggests that it reduces elevated cholesterol to a modest extent.
心脏病迅速增长的发病率和死亡率是科学家们非常关注的问题。在动脉粥样硬化的病因中,血脂异常是一个重要的危险因素。大蒜含有大蒜的有效成分,用于高血压管理。大蒜已被用作许多疾病的治疗剂,如高血压、血脂异常和心血管疾病。来自各种研究和临床试验的证据证明了大蒜降低血脂水平的功效。然而,也报道了一些相互矛盾的结果。本综述旨在评估大蒜治疗血脂异常的作用。主要数据库包括谷歌、PubMed、MEDLINE和Cochrane图书馆视图。对人体进行的临床试验评估了大蒜治疗血脂异常的作用,并评估了这种治疗作用的可能机制。多项试验和荟萃分析表明,大蒜对总胆固醇(TC)、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)和甘油三酯(TG)有积极作用。这篇关于大蒜治疗血脂异常的综述表明,它可以在一定程度上降低升高的胆固醇。

This study was conducted to describe in morphometrical traits and body weight (BW) of indigenous goat populations reared in Belatal, Ajnar, Chhitarwara, Lamaura and Budhaura village of Jaitpur block in Mahoba. Data were obtained from 549 goats from 107 households. The BW and height at withers (HW) in Ajnar, Belatal and Budhaura doe aged 1-2 years were significantly high compared to others. Doe of Budhaura, Ajnar, Belatal and Chhitarwara had significantly high body length (BL). Significantly high chest girth (CG) values were obtained from Chhitarwara had Budhaura doe. Buck of Ajnar, Belatal and Lamaura had significantly high BW, BL and HW.  Body weight of Belatal, Ajnar and Chhitarwara doe aged 1-2 years and bucks were better estimated using CG alone. However, the best predictor for Belatal, Ajnar and Chhitarwara doe aged 1-2 years old were CG, HW and BL. CG was the primary variable to explain most of the variations in BW. Budhaura and Ajnar goat had a relatively large body frame and emphasis may be given for their improvement.

Cattle rearing plays a crucial role in the semi arid communal areas of Zimbabwe, as a result any developmental strategy that is aimed at improving household livelihood in these areas should target cattle production. The objective of the study was to assess the impact of introducing improved indigenous cattle beef breeds in Bulilima District of Matabeleland South in Zimbabwe. The study was carried out in Masendu ward comprising of six villages of Luvuluma, Mambo, Tjeboroma, Makumbi, Thandawani and Muke. A random sample of 13 livestock farmers were selected from participants of the Kellogg Foundation communal areas indigenous cattle (Tuli, Afrikaner and Nguni) improvement program through a donation of  improved indigenous beef cattle bulls. Semi-structured questionnaires were used to collect data on household demographics, socioeconomic factors, herd structure, management practices and constraints in cattle breeding program. Qualitative data were coded and analyzed using the Statistical Package for Social Sciences (SPSS 2008) computer software in order to generate descriptive statistics such as means and frequencies or percentages. The study revealed an interesting scenario on household demographics; the majority of the farmers had formal education, with only 7.7% not having attained any formal education. As a result of Kellogg Foundation bull donations some farmers (15.4%) increased their herd size to more than 30 cattle which improved their social status in the areas. Farmers interviewed showed that they were motivated to keep improved breeds with least more than half of the farmers reporting that the bulls to a certain extent increased the number of cows serviced within the community herds. Poor animal condition was reported in cattle herds due to the inadequate supply of both water and nutrition, the latter being caused by lack of good grazing. It was noted that government support was necessary in infrastructure development in order to improve community based cattle breeding programs. The need to organise market to encourage smallholder farmers to sell their animals was also cited. There was a belief that better prices were achievable at local markets if the communal herd was genetically improved for important economic traits.

养牛在津巴布韦半干旱的社区地区起着至关重要的作用,因此任何旨在改善这些地区家庭生计的发展战略都应以养牛为目标。这项研究的目的是评估在津巴布韦南马塔贝莱兰的Bulilima区引进改良的本地牛肉品种的影响。这项研究是在马森杜区进行的,包括卢武卢马、曼博、Tjeboroma、马库姆比、坦达瓦尼和穆克六个村庄。通过捐赠改良的土著肉牛,从凯洛格基金会公共地区土著牛(图利牛、阿非利卡牛和恩古尼牛)改良项目的参与者中随机抽取13名畜牧农民作为样本。采用半结构化调查问卷收集了家庭人口统计、社会经济因素、牛群结构、管理实践和牛养殖计划制约因素等方面的数据。使用社会科学统计软件包(SPSS 2008)计算机软件对定性数据进行编码和分析,以生成描述性统计数据,如平均值和频率或百分比。这项研究揭示了一个有趣的家庭人口统计情况;大多数农民接受过正规教育,只有7.7%的农民没有接受过任何正规教育。由于凯洛格基金会的牛捐赠,一些农民(15.4%)将他们的牛群规模增加到30多头,提高了他们在该地区的社会地位。接受采访的农民表明,他们有动力饲养改良品种,至少有一半以上的农民报告说,公牛在一定程度上增加了社区牛群中服务的奶牛数量。据报告,由于水和营养供应不足,牛群的动物状况很差,后者是由于缺乏良好的放牧造成的。会议指出,为了改善以社区为基础的养牛项目,政府在基础设施建设方面的支持是必要的。他们还提到,有必要组织市场,鼓励小农出售他们的牲畜。有一种观点认为,如果公共畜群在重要的经济性状上进行了基因改良,那么在当地市场上可以获得更好的价格。因此,关键结论是社区农民对改善社区牛群有积极的看法。这就需要采取多部门办法,以应对妨碍公共地区提高牛生产力的各种挑战。

The objective of the study was to assess the impact of introducing improved indigenous cattle beef breeds in Bulilima District of Matabeleland South in Zimbabwe. The study was carried out in Masendu ward comprising of six villages of Luvuluma, Mambo, Tjeboroma, Makumbi, Thandawani and Muke. A random sample of 13 livestock farmers were selected from participants of the Kellogg Foundation communal areas indigenous cattle (Tuli, Afrikaner and Nguni) improvement program through a donation of  improved indigenous beef cattle bulls. Semi-structured questionnaires were used to collect data on household demographics, socioeconomic factors, herd structure, management practices and constraints in cattle breeding program. Qualitative data were coded and analyzed using the Statistical Package for Social Sciences (SPSS 2008) computer software in order to generate descriptive statistics such as means and frequencies or percentages. The study revealed an interesting scenario on household demographics; the majority of the farmers had formal education, with only 7.7% not having attained any formal education. As a result of Kellogg Foundation bull donations some farmers (15.4%) increased their herd size to more than 30 cattle which improved their social status in the areas. Farmers interviewed showed that they were motivated to keep improved breeds with least more than half of the farmers reporting that the bulls to a certain extent increased the number of cows serviced within the community herds. Poor animal condition was reported in cattle herds due to the inadequate supply of both water and nutrition, the latter being caused by lack of good grazing. It was noted that government support was necessary in infrastructure development in order to improve community based cattle breeding programs. The need to organise market to encourage smallholder farmers to sell their animals was also cited. There was a belief that better prices were achievable at local markets if the communal herd was genetically improved for important economic traits.

To investigate antibiotic therapy with pregnant women to asymptomatic bacteriuria (AB) in Prenatal Consultation (PNC) without prior urinary tract infection at the moment of the visit in Lome health center. The urines were collected following the rules on hygienic good practices. We conducted the systematic urine culture on a chromogenic medium (Uriselect4). It enables us to identify a specific enzyme of a bacterial species or a group of species. The susceptibility was carried out following the agar - based spreading method. The following strains were the main uropathogensisolated, Escherichia coli, Klebsiella pneumonia, Enterobacterclaocea, Staphylococcus aureus, Streptococcus agalactiae, Enterococcusfecalis. Antibiotic discs from the family of Beta – lactam, lincosamide, polypeptic and quinolone were tested on various bacterial strains. All bacterial strains were resistant to ampicillin and amoxcilline. Staphococcusaureus presented resistance to cefoperazone, erythromycin and spiramycin. Enterococcusfaecalis was resistant to cephalothin, ceftazidime and chloramphenicol. The susceptibility was stressed with the view of achieving an adapted antibiotic therapy with zero effect on the foetus and the future mother.

The current goat production status and contribution to the total meat gross domestic product is still regarded as low in Sub Saharan Africa. Among some of the reasons given for unsatisfactory smallholder goat production contribution to household livelihoods is failure to understand the flock dynamics, production performance and reproductive capacity in smallholder farming sector. It is hoped that the understanding of flock dynamics, reproductive performance traits and production characteristics may assist in formulation of appropriate livestock intervention strategies to improve goat production in smallholder farming sector on the continent. Implementation of sound goat intervention stategies should be based on reproductive and productive performance monitoring data in smallholder livestock sector.  However, it is acknowledged that this approach need to be complemented with other aspects of improved general goat management such as adequate nutrition and health management. The purpose of this discussion is to explore significance of understanding flock dynamics, reproduction and production characteristics in order to increase goat contribution to smallholder household livelihood.
在撒哈拉以南非洲地区,山羊目前的生产状况和对肉类国内生产总值的贡献仍然很低。小农山羊生产对家庭生计的贡献不理想的一些原因是不了解小农农业部门的羊群动态、生产绩效和繁殖能力。希望通过对羊群动态、繁殖性能特征和生产特征的了解,有助于制定适当的牲畜干预策略,以提高非洲大陆小农农业部门的山羊产量。实施健全的山羊干预战略应以小农畜牧业的繁殖和生产绩效监测数据为基础。然而,人们认识到,这种办法需要与改进一般山羊管理的其他方面相辅相成,例如适当的营养和健康管理。本文旨在探讨了解羊群动态、繁殖和生产特征对提高山羊对小农家庭生计的贡献的意义。

Two-hundred (200) day old broiler chicks of Anak 2000 breed from a commercial hatchery were used to investigate the effect of replacing wheat offals with sweet orange peel meal in broiler rations.  The birds were fed on 0%, 50%, 75% and 100% dietary inclusion of sweet orange peel meal as replacement for wheat offals in a 28 day feeding trial.  Significant interaction between dietary levels of sweet orange peel meal and wheat offals were observed on feed efficiency and weight gain (p<0.05).  Increase in dietary levels of sweet orange peel meal reduced feed transit time in gastro-intestinal tract (GIT) (p<0.05) while supplementary wheat offal had the opposite effect (p<0.05).  It was concluded that broiler chicks could tolerate up to 75% dietary levels of sweet orange peel meal without wheat offal added to such a diet, performance was comparable to that of birds fed a standard diet with money saved in the process.
以某商业孵化场的200日龄Anak 2000品种肉鸡为试验对象,研究了用甜橙皮粕代替小麦内脏对肉鸡日粮的影响。在28 d的饲粮中分别添加0%、50%、75%和100%的甜橙皮粉替代小麦内脏。饲粮添加甜皮粕和小麦内脏对饲料效率和增重有显著交互作用(p<0.05)。饲粮中添加甜橙皮粉可缩短饲料在胃肠道的转运时间(p<0.05),添加小麦内脏则相反(p<0.05)。综上所述,在不添加小麦内脏的情况下,肉仔鸡可耐受高达75%饲粮水平的甜橙皮粉,其生产性能与饲喂标准饲粮的鸡相当,并且节省了成本。
