This project examines social dynamics of North African dama gazelles (Nanger dama ruficollis) under different combinations in a large, 202 ha, rangeland pasture in Central Texas, USA. There are many wildlife ranches in this part of Texas that keep herds of these critically endangered dama gazelles. Therefore, an increased understanding of how these pasture animals may assort themselves under different social combinations can not only help managers sustain and grow their herds but also bolster the numbers that give the species a better chance to remain viable while status in their native countries remains precarious. Investigated were: (1) 7 adult females with one adolescent male and one young adult male, (2) the same adult females and immature male without any adult males, (3) the same adult females and the young, now maturing, male with multiple adult males. It was shown that multiple adult males can co-exist in large pastures with minimal aggression, even when females are present, provided there is informed management. All the gazelles wore GPS-radio collars (7 adult females, 1 immature male, and 1-to-3 adult males depending on phase of the project). Locations were recorded every 3 hr. Visual observations were made monthly. Project duration was December 19, 2014, until June 30, 2016. Without the initial adult male, the female herd split and association values declined. With new adult males added, 2 divided the pasture, thus, separating spatially. The maturing male kept his core area where the main female group stayed, but now separated temporally. Adult males focused on areas favored by females but did not direct the movements of the females. These males did not associate as closely with females as females did with each other. Estimating maximum possible adult males for a pasture must allow for slope, vegetation density, and sites favored by females. The only two similar studies determined larger core areas under more xeric conditions, but these other studies could not assess group dynamics in detail without collars on more animals.
本项目在美国德克萨斯州中部一个202公顷的大型牧场牧场,研究了不同组合下北非大瞪羚(Nanger dama ruficollis)的社会动态。在德克萨斯州的这一地区有许多野生动物牧场,饲养着这些极度濒危的大瞪羚。因此,增加对这些牧场动物如何在不同社会组合下进行自我分类的了解,不仅可以帮助管理者维持和扩大他们的畜群,而且还可以增加数量,使该物种在其本国的地位仍然不稳定的情况下有更好的机会保持生存。调查对象为:(1)7只成年雌虫,有1只青春期雄虫和1只年轻成年雄虫;(2)同一只成年雌虫和未成熟雄虫,无成年雄虫;(3)同一只成年雌虫和正在成熟的年轻雄虫,有多只成年雄虫。研究表明,如果有明智的管理,即使有雌性存在,多只成年雄性也可以以最小的攻击性共存于大型牧场。所有的瞪羚都戴着gps无线电项圈(7只成年雌性,1只未成熟雄性,1到3只成年雄性,具体取决于项目的阶段)。每3小时记录一次位置。每月进行一次目视观察。项目时间为2014年12月19日至2016年6月30日。没有最初的成年雄象,雌象群分裂,群体价值下降。随着新的成年雄鹿的加入,两只雄鹿将牧场分割开来,从而在空间上进行分离。成熟的雄鸟一直保持着它的核心区域,主要的雌鸟群就呆在那里,但现在暂时分开了。成年雄性专注于雌性喜欢的区域,但不指导雌性的行动。这些雄性与雌性之间的关系不如雌性与雌性之间的关系密切。估计牧场上最大可能的成年雄性必须考虑到坡度、植被密度和雌性喜欢的地点。仅有的两项类似研究确定了在更干燥的条件下更大的核心区域,但其他研究无法在没有项圈的情况下详细评估群体动态。

Pork farm animals have massive function in imparting protein meals for consumers. The take a look at become performed in Hawa Gelan district, Kellem Wollega Zone Western Oromia Ethiopia with the goal to Assessment on Challenges and Opportunities of Beef Cattle Production. Assessment on challenges and opportunities of beef cattle production was carried out on 80 farmers in the study district. Majority of the respondents has been used blended manufacturing device (50%) due to the fact maximum of the red meat farm animals manufacturers had been they take part in crop manufacturing, farm animals rearing sports and dealer game. The end result of this take a look at shows that 45% of the respondents rely upon herbal pasture, 22.5% of crop residues, 15% of sparkling grass cutting, 7.5% of sugar cane and 10% of maize grain as a basal feed for his or her farm animals.

猪场动物在为消费者提供蛋白质膳食方面发挥着巨大的作用。该调查在埃塞俄比亚西部奥罗米亚州Kellem Wollega地区的Hawa Gelan地区进行,目的是评估肉牛生产的挑战和机遇。对研究区80户肉牛养殖户进行了肉牛生产面临的挑战和机遇评估。大多数受访者使用混合生产设备(50%),因为大多数红肉农场动物制造商都参与了作物生产、农场动物饲养运动和经销商游戏。这一调查的最终结果表明,45%的受访者依赖草本牧草、22.5%的作物残茬、15%的气泡草切割、7.5%的甘蔗和10%的玉米谷物作为其农场动物的基础饲料。87.5%的受访者表示生猪广告和交易的价格意志力是通过卖家/制造商和客户之间的谈判达成的,12.5%的受访者表示代理商在卖家/制造商和客户之间进行了干预。首要供水由河水、自来水和池塘决定。育肥牲畜的供应主要来自市场(购买,78.75%),其余来自个人畜群,10%和11.25%来自两者。饲料短缺、饲料成本、土地短缺、住房不足、遗传方面以及黑腿病、疙瘩状毛孔和皮肤病、巴氏杆菌病、炭疽病、腹胀和寄生虫等疾病的发生是猪肉农场动物制造业面临的最严峻的问题。饲料短缺的根本原因是土地流失、饲料费用过高和偶尔的大补饲料量。当生产者收到用于饲草生产的土地时,必须使用高级饲草。有关部门必须抓紧引进高产量饲料,并在饲料生产设备之外专门采用饲料改良技术,才能从很大程度上解决饲料短缺问题。政府必须加强猪肉农场动物产品的广告联动。在命运中,必须通过当局与所有利益相关者合作的方式来解决在查看区域中引用的限制,并且必须在这些基础上改进可能性。

Tanaman obat yang dimanfaatkan sebagai bahan campuran pada ransum unggas belum banyak dilakukan meskipun telah banyak digunakan oleh manusia, perlu dilakukan pengujian mengingat permintaan serta preferensi konsumen yang semakin kritis pada bahan makanan yang dikonsumsi. Pengumpulan data penelitian dilakukan mulai 1 maret sampai 30 maret 2021 di kandang bapak Mukarap Desa Ngayung kecamatan Maduran Kabupatan Lamongan. Riset bertujuan guna mengetahui pengaruh pemberian tepung daun mengkudu pada ransum terhadap bobot badan ayam kampung. Hasil penelitian diharapkan mampu digunakan sebagai informasi mengenai penggunaan tepung daun mengkudu pada level berapa sehingga menambah nafsu makan yang memiliki guna meningkatkan bobot badan ayam kampung. Materi riset yakni ayam kampung yang berada di kandang bapak Mukarap Desa Ngayung Kecamatan Maduran Kabupatan Lamongan sebanyak 36 ekor ayam kampung yang berumur 3 bulan. Riset menggunakan metode percobaan dengan Rancangan acak lengkap yang terdiri dari 4 perlakuan serta 3 ulangan, adapun perlakuan tersebut yakni dengan pemberian tepung daun mengkudu 5%, 10%, 15% dari ransum. Selama penelitian variabel yang diamati yakni penambahan bobot badan ayam kampung dengan varian kemudian dilanjut dengan uji beda nyata terkecil. Hasil riset menunjukkan bahwa bobot badan ayam kampung berbeda sangat nyata pada taraf signifikan 5% (P<0,05 ) dan 1% (P<0,01). Sedangkan pada konsumsi pakan tidak berbeda nyata pada taraf signifikan 5% dimana F hitung 0,271 lebih kecil dari F tabel 1% (4,07) terhadap konsumsi pakan. Percobaan ini merekomendasikan bahwa tepung daun mengkudu dapat diberikan sebanyak 10% terhadap ransum ayam kampung agar mendapat performan dan produktifitas yang optimal.
尽管人类广泛使用了这种用于家禽配给的药用植物,但由于消费者对家禽消费品的需求和偏好越来越挑剔,因此,用于测试的草药并没有多大用处。研究数据收集是从3月1日到2021年3月30日在Mukarap村Mukarap Maduran街道街道上进行的。研究的目的是确定叶粉对家禽体重的影响。研究结果预计将用于研究如何使用淀粉,以增加鸡的食欲,以增加鸡的体重。研究材料包括在kaap村Mukarap的Maduran街,拥有36个月的Maduran街。研究采用了一种由4种治疗方法和3种申命记组成的随机设计的实验方法,即用淀粉制成5%、10%和15%的口粮。在观察到的变量研究中,鸡的体重增加有变种,然后进行真正的测试。研究表明,家禽的体重在重要水平上有显著的5% (P< 0.05)和1% (P< 0.01)。而在重要的5%上,F的计数为F 271比F表1%(4.07)的饲料消费要小得多。这个实验建议,可以给棕榈叶10%的家禽配给,以获得最佳的业绩和生产力。

Penelitian bertujuan guna mengetahui pengaruh penambahan tepung tepung kunyit (Curcuma domestica val) pada pakan komersil terhadap kualitas fisik telur puyuh (Cortunix cortunix japonica) dilihat dari tebal kerabang, warna kuning telur, indeks kuning telur, indeks telur serta Haugh Unit telur puyuh. Materi pada riset yakni telur puyuh yang dihasilkan dari burung puyuh ras hitam yang diberikan ransum pakan komersial dan pakan tambahan tepung kunyit. Penelitian memakai metode Analisa laboratorium dengan Rancangan Acak Kelompok (RAK) diantaranya empat macam perlakuan serta ulangan lima kali dengan penambahan 100%+0%, 97%+3, 96%+4%, dan 95%+5%. Variabel yang di amati pada penelitian yakni Mengamati kualitas fisik telur diantaranya tebal kerabang, warna kuning telur, Indeks kuning telur,  Indeks telur, serta Haugh unit telur puyuh. Perolehan data kemudian ditabulasi serta dianalisa dengan analysis of variance (ANOVA). Apabila ada perbedaan, dilakukan Uji Jarak Berganda Duncan (UJBD) guna mengetahui perlakuan yang paling baik. Hasil penelitiaan menunjukkan bahwa tepung kunyit dengan pemberian taraf (3%,4%, dan 5%) pada pakan komersial tidak memberi pengaruh terhadap kualitas fisik (tebal kerabang, indeks kuning telur, indeks telur, haugh unit telur) tetapi memberikan pengaruh yang nyata pada warna kuning burung puyuh (Coturnix coturnix japonica). Tepung kunyit yang ditambahkan pada pakan komersial mengasilkan nilai rataan tebal kerabang telur puyuh yakni 0,392 – 0,444 mm. Nilai rataan skor warna kuning telur puyuh adalah 4,627 – 5,640. Nilai rataan indeks kuning telur puyuh adalah 0,434 – 0,441. Rataan nilai indeks telur puyuh adalah 77,784 – 78,794%. Nilai rataan haugh unit telur puyuh adalah 86,583 – 91,227.
该研究旨在确定将鹌鹑蛋的蛋黄、蛋黄颜色、蛋黄索引、蛋黄索引以及Haugh单位的蛋黄对商业饲料(Cortunix Cortunix japonica)的影响。研究的材料是一种黑鹌鹑蛋,这种鹌鹑的食物是由商业饲料和藏红花面粉制成的。研究采用了一种随机设计的实验室分析方法,设计了四种治疗方案和五种重复,分别是100%+0%、97%+3、96%+4%和95%+5%。研究中观察到的变量是观察蛋黄、蛋黄颜色、蛋黄索引、蛋黄索引以及Haugh单位的物理质量。然后通过分析变量进行分析和分析数据。如果存在差异,就进行对比度测试,以确定最佳治疗方法。研究结果表明,商业饲料中藏红花粉的含量(3%、4%和5%)对身体质量(腰酸化、蛋黄索引、蛋黄索引、蛋黄带)没有影响,而是对鹌鹑黄色(Coturnix Coturnix japonica)有明显的影响。商业饲料中加入的藏红花粉使鹌鹑蛋的腰围为0.392——0.444毫米。鹌鹑蛋黄的得分为4.627 - 5.640分。鹌鹑蛋黄黄指数为0.434—0.441。鹌鹑蛋指数的值为77.784——78.794%。rataan haugh单位的鹌鹑蛋值为86,583——91.227。

Tujuan dari penelitian ini iyalah untuk memahami alur dsitribusi tataniaga telur puyuh milik bapak budi, unsur-unsur pemasaran yang terlibat, share keuntungan yang di dapat pedagang dan efisiensi pemasaran yang di peroleh peternak telur puyuh. Metode yang digunakan yakni metode sampling (purposive random sampling dan proposional random sampling. Data di dapat dengan melaksanakan observasi dan interview langsung kepada peternak beserta unsur yang terlibat dalam pemasaran. kemudian dianalisis secara deskriptif dan kuantitatif. Hasil penelitian ini menunjukkan bahwa alur distribusi yang terbentuk terdapat satu pola yaitu pola I. untuk pola I didominasi pedagang besar (pengepul), pasar (penjual dan pengecer), peagang pengecer (toko) kemudian konsumen. Unsur-unsur pemasaran yang terlibat diantaranya  adalah Peternak telur puyuh  ( produsen) - Pedagang Besar (prngepul)-Pasar (penjual dan pengecer)-pedagang pengecer (toko) dan konsumen. Share keuntungan yang diperoleh pedagang tertinggi adalah pedagang pasar (penjual dan pengecer) yakni sebesar (7,0%) dikarenakan pedagang ini membeli telur puyuh dari pedagang besar (pengepul) dengan harga Rp. 21,000/Kg. Kemudian dijual kembali kepada konsumen akhir/konsumen di pasar maupun kepada pedagang pengecer (toko) dengan harga Rp.22.000/Kg (menyesuaikan harga pasar), Sedangkan  Share keuntungan terendah di peroleh pedagang pengecer (toko) dikarenakan unsur ini membeli telur puyuh dengan harga Rp. 22.000 – 23.000/Kg dari pedagang pasar (penjual dan pengecer) dan dijual kembali kepada konsumen dengan harga Rp.22.000-2300/Kg + kerugian yang didapat karna kebusukan telur maupun pecah saat perjalanan, jadi semakin besar populasi ternak maka semakin efisien pemasaran yang diterima oleh peternak.

The major constraint of livestock farming in Burkina Faso is the feed gap. This study aims to provide information on feed resources, availability, and uses in Bama's district. Feed Assessment Tool (FEAST) was used to evaluate feed resources and to generate possible interventions. Focus groups were held and took into account 140 farmers, of which 90 were recalled for individual surveys. We found that the Bama district was characterized by agropastoral production systems in which crop provides 65.1% of household income whereas 23.9% was from livestock. Livestock feeding throughout the year depended on natural grazing. Natural pastures contributed most often to dry matter, metabolizable energy, and crude protein in animals' total diet, respectively, with 65.4, 64.4, and 61.5%. In addition to grazing, crop residues were collected after harvest to form a dietary supplement for the animals. The study also revealed nutritional gaps, and farmers were purchasing concentrates to compensate and ensure the best livestock productivity. The dominant complement purchased was cotton cake at a rate of 623.1 kg/year/household. None of the agropastoralists grew fodder crops. Identified interventions able to improve productivity and production of animals were supplementations with: a high-energy supplement (molasses); protein byproducts; pruning products, aerial parts, and leaf-stripping without sacrificing grain/tuber yields; cereal byproducts (rice bran, corn, wheat); multi-nutritional blocks; and commercially balanced feed. Given the food shortage, especially in the dry season, better management of food resources through the collection and conservation of fodder and the adoption of forage crops could increase feed availability.
布基纳法索牲畜养殖的主要制约因素是饲料缺口。本研究旨在提供有关巴马地区饲料资源、可用性和使用情况的信息。采用饲料评估工具(FEAST)对饲料资源进行评估,并提出可能的干预措施。召开了焦点小组,对140名农民进行了调查,其中90人被召回进行个别调查。研究发现,巴马地区以农牧生产系统为特征,作物收入占家庭收入的65.1%,牲畜收入占家庭收入的23.9%。一年四季的牲畜饲养都依靠自然放牧。天然草场对动物总日粮中干物质、代谢能和粗蛋白质的贡献最大,分别为65.4、64.4和61.5%。除放牧外,收获后收集作物残余物作为动物的膳食补充剂。该研究还揭示了营养缺口,农民正在购买浓缩物来弥补并确保最佳的牲畜生产力。棉花饼是主要补品,年购买量为623.1 kg/户。农牧民都不种饲料作物。确定的能够提高动物生产力和产量的干预措施是补充:高能量补充剂(糖蜜);蛋白质的副产品;不牺牲籽粒/块茎产量的修剪产品、地上部分和剥叶;谷物副产品(米糠、玉米、小麦);multi-nutritional块;商业平衡饲料。鉴于粮食短缺,特别是在旱季,通过收集和保存饲料和采用饲料作物来更好地管理粮食资源可以增加饲料供应。

An experiment was conducted to assess the effect of millet and sorghum as alternatives to maize. on performance and egg production parameters of quails. Three hundred (300) day old quails were sourced form National Veterinary Institute Jos. The birds were brooded for two weeks and randomly allotted to three (3) different energy sources i.e. maize, millet and sorghum designated as treatment 1, 2 and 3 respectively. The birds were fed with experimental diets for six months. Results showed daily feed intake (68.35-79.86), daily weight gain (3.41-3.43) and feed conversion ratio (3.33-3.91) were not affected by the different energy sources (P>0.05). Most of the carcass parameters were statistically similar (P>0.05). The hen day egg production (80.21-84.51) and egg production parameters were not affected by the alternative energy sources (P>0.05), similarly hematological parameters showed that packed cell volume (50.20-56.00), red blood cells (4.72-5.21) and hemoglobin (16.98-18.38) were statistically similar (P>0.05). The serum biochemical parameters showed that total protein (36.20-39.80), globulins (11.60-14.44), total protein (36.20-39.80), glucose (12.68-14.82), cholesterol (5.36-6.78), urea (17.80-20.00) and ASAT (1.98-2.08) were not affected by the different energy sources (P>0.05). I It can be concluded that millet and sorghum can be alternative energy sources in quail production in semi-arid environment of Gashua Yobe state with reduction in cost of production.
研究了谷子和高粱作为玉米替代品的效果。鹌鹑生产性能及产蛋参数的研究。300只日龄鹌鹑来自乔斯国立兽医研究所。雏鸟孵育2周,随机分配3种不同的能量来源,即玉米、小米和高粱,分别作为处理1、2和3。这些鸟用试验饲料喂养了六个月。结果表明:日采食量(68.35 ~ 79.86)、日增重(3.41 ~ 3.43)和饲料系数(3.33 ~ 3.91)不受不同能量来源的影响(P < 0.05)。大部分胴体参数差异有统计学意义(P < 0.05)。替代能源对母鸡日产蛋量(80.21 ~ 84.51)和产蛋参数无显著影响(P>0.05),相似的血液学参数显示,堆积细胞体积(50.20 ~ 56.00)、红细胞(4.72 ~ 5.21)和血红蛋白(16.98 ~ 18.38)差异有统计学意义(P>0.05)。血清生化指标显示,不同能量来源对总蛋白(36.20 ~ 39.80)、球蛋白(11.60 ~ 14.44)、总蛋白(36.20 ~ 39.80)、葡萄糖(12.68 ~ 14.82)、胆固醇(5.36 ~ 6.78)、尿素(17.80 ~ 20.00)和ASAT(1.98 ~ 2.08)均无显著影响(P < 0.05)。综上所述,谷子和高粱可作为半干旱环境下Gashua Yobe州鹌鹑生产的替代能源,且可降低生产成本。

Tripterygium glycosides (TG) is isolated from an extensively used traditional Chinese medicine herb tripterygium roots and has been extensively used in the treatment of rheumatoid arthritis, nephrotic syndrome, hyperthyroidism and other diseases due to its anti-inflammatory and immunosuppressive effects. Hearing toxicity has been recently associated with TG use in human patients. In this study, authors assessed hearing toxicity and possible molecular toxic mechanisms of TG in a whole animal model. The maximum non-lethal concentration (MNLC) of TG on the zebrafish was 21 mg/L. TG induced zebrafish hair cell loss in a dose-dependent manner (p<0.001), and the saccular otolith size reduction when treated at MNLC (p<0.01). TG treatment resulted in sound-stimulated zebrafish movement reduction (p<0.001); and the rollover zebrafish percentages were elevated as TG treatment concentrations moved up. Following TG treatment, mRNA levels of the zebrafish hearing organ development genes eya1 and val were remarkably downregulated, and the expression of apoptosis-associated genes bax and caspase3 was significantly enhanced (p<0.05). These findings confirm the hearing toxicity of TG and suggest its toxic mechanisms probably are through suppressing hearing cell development and promoting hearing cell apoptosis. Authors recommend zebrafish assay as a quick and reliable screening test of hearing toxicity for drugs and health products.
雷公藤苷(triterygium glycosides, TG)是从一种广泛使用的中药雷公藤根中分离出来的,因其具有抗炎和免疫抑制作用,被广泛用于治疗类风湿性关节炎、肾病综合征、甲状腺功能亢进等疾病。听力毒性最近与人类患者使用TG有关。在本研究中,作者在全动物模型中评估了TG的听力毒性和可能的分子毒性机制。TG对斑马鱼的最大非致死浓度(MNLC)为21 mg/L。甘油三酯诱导斑马鱼毛细胞损失呈剂量依赖性(p<0.001),在MNLC处理时,囊状耳石大小减小(p<0.01)。TG治疗导致声刺激斑马鱼运动减少(p<0.001);随着TG处理浓度的升高,翻转斑马鱼的百分比升高。TG处理后,斑马鱼听觉器官发育基因eya1、val mRNA表达水平显著下调,凋亡相关基因bax、caspase3表达水平显著升高(p<0.05)。这些发现证实了TG的听力毒性,并提示其毒性机制可能是通过抑制听力细胞发育和促进听力细胞凋亡。作者推荐斑马鱼试验作为药物和保健产品的听力毒性快速可靠的筛选试验。
