A consumer questionnaire conducted with the purpose of ascertaining the acceptability of goat milk and related products in Japan was carried out on 345 guarantees of Nippon Veterinary and Life Science University in December 2006. 275 effective responses (79%) representing middle class urban households were returned. The results revealed that (1) 30% of respondents have experienced drinking goat milk and only 10% are aware of the current retail situation of goat milk and related products; (2) over 70% of goat milk drinkers raised goats by hand at some point in their past and their first experience drinking goat milk was in infancy; (3) those with experience in drinking goat milk expressed a vague evaluation and minimal understanding of drinking goat milk; (4) respondents who were inexperienced goat milk drinkers expressed a strong desire to taste and a weak desire to purchase goat milk; (5) respondents expressed low recognition regarding retailed goat milk products, but those who had already purchased goat milk products expressed a high evaluation and strong desire to purchase these products again; and (6) recognition of goat milk characteristics is low, but those with high recognition also rate goat milk highly. Goats are perceived as being 'mild and familiar.' It is necessary for those who manage goat husbandry to present goat milk and related product tasting opportunities to consumers. The key point is to make the functional differences between cow and goat milk clear and present the advantages of goat milk at the fore of this promotion. Goat milk should not be promoted merely as a drink that is similar to cow milk, but must be positioned as a functional drink or health food in order to expand the Japanese goat milk market. 相似文献

对在延安南部次生林林间草地四季放牧的安哥拉公羊的采食量和消化率测定结果:成年公羊四季干物质平均采食量每kg代谢体重分别为99.6±14.5g,102.3±19.8g,71.9±3.1g和61.6±8.3g;周岁公羊分别为91.4±15.2g,118.1±6.5g,94.0±7.7g和82.5±6.2g。四季牧草干物质消化率成年公羊分别为76.22%,75.72%,58.16%和36.05%;周岁公羊分别为77.10%,79.84%,68.43%和36.60%。根据测定结果,认为放牧安哥拉公羊的补饲时间应始于9月下旬,终于来年4月底;周岁公羊延长至5月上旬。 相似文献

采用Danscher氏组织学技术测定了口服不同剂量亚硒酸钠中毒奶山羊的心脏、肝脏、脾脏、肺脏、肾脏和大脑硒含量与分布状态;探讨了各组织器官局部病变程度与硒分布密度之间的内在联系。结果表明,中毒羊各组织器官,尤其是发生病理变化的局部组织均蓄积不同密度的反应产物;各组织局部病变程度与硒的分布密度有关,Danscher组织化学技术将组织硒含量与病理变化程度联系起来,为研究动物中毒病的一个实用手段。 相似文献

山羊圈养具有提高成活率和生产效益,保护生态环境,促进畜牧业的可持续发展的优势。但由于养殖密度大,如饲养管理不到位,增大了疫病爆发的机率。本文以武鸣县宁武镇圈养山羊为例,分析山羊圈养发生疫病的原因,总结饲养经验,从加强基础设施建设、搞好饲养管理、建立卫生消毒制度、规范疫病免疫程序等几个方面进行阐述,提出圈养山羊防控疫病具体措施。 相似文献

为了解重庆市山羊博尔纳病隐性带毒情况,分析博尔纳病病毒(BDV)的种系来源。采用巢式逆转录酶PCR结合荧光定量PCR(FQ—nRT—PCR)技术对重庆市60只山羊外周血单核细胞(PBMCs)及脑组织中的BDVP24基因片段进行了检测,将阳性产物测序,并与国外BDV毒株进行了比较。结果,山羊外周血检测阳性率为8.3%(5/60),脑组织检测阳性率为10%(6/60)。该BDVP24片段核苷酸序列与马源BDVH1766株同源性最高,达96.519/6,与标准株Strain V和He/80同源性为95.35%,并且编码的氨基酸序列也相同。表明,重庆市山羊中存在动物源性博尔纳病隐性带毒,该BDVP24核苷酸序列与Strain V和He/80株具有高度同源性。 相似文献

We evaluated forage production patterns, weight gains and blood parameters when lambs (Ovis aries) and meat‐goat (Caprus hircus) kids were finished on a mixed sward of cocksfoot (Dactylis glomerata L.), red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) with (SUP) and without (UNSUP) supplemental whole cottonseed (Gossypium hirsutum; WCS) in a replicated study. Botanical composition and energy/protein ratios of the sward varied with year and with time during the growing season. Swards had greater amounts of red clover relatively early and more cocksfoot later in the season. Suffolk (SX) lambs had the heaviest body weights, Katahdin (KA) lambs were intermediate, and meat‐goat (GX) kids were the lightest at the end of each year. Overall body weight gain followed a trend of SX > KA > GX, and WCS supplementation increased weight gain for all animals by 18%. Only in 2008 did SUP animals have higher blood urea nitrogen levels, which may indicate less efficient use of dietary nitrogen when grazing grass–legume pastures managed for high nutritive value compared with UNSUP animals. Gossypol in WCS did not affect blood packed cell volume between SUP and UNSUP lambs and meat‐goat kids. Suffolk lambs, Katahdin lambs and cross‐bred Boer meat‐goat kids finished on pasture with and without WCS supplementation produced desirable body weights for most ethnic markets in the USA. 相似文献

为促进崇明白山羊实验动物化应用和临床诊断提供数据,本研究采用全自动血细胞分析仪,对上海市崇明地区不同性别和生理状态的185只健康崇明白山羊19项主要血液生理指标进行测定。结果显示:后备母羊,妊娠母羊,哺乳母羊,成年母羊,成年公羊,断奶小母羊,断奶小公羊,哺乳小羊之间嗜酸性粒细胞计数(EO)指标差异显著(P<0.05),中性粒细胞计数(NEUT),嗜碱性粒细胞计数(BASO),嗜碱性粒细胞百分比(BASO%)3项指标差异不显著(P>0.05),其他15项指标差异均极显著(P<0.01)。说明不同性别和生理状态的崇明白山羊部分血液学指标波动范围有一定的差异。 相似文献

光周期可以影响动物体内褪黑素(MLT)的分泌,而MLT能参与机体多种生理功能的调节。本试验旨在研究光周期对山羊MLT分泌、免疫和抗氧化功能及相关基因表达的影响。将18只6月龄雌性绒山羊随机分为3组:对照(CG,自然光周期)组、短光照(SDPP,光照8 h/d,黑暗16 h/d)组和渐减光照(SIPP,光照时间从16 h/d逐渐缩短到8 h/d)组。试验期为60 d。结果表明:与对照组相比,1)在试验第30天,SDPP显著增加了血清MLT含量(P<0.05),在试验第60天,SIPP显著增加了血清MLT含量(P<0.05);2)在试验第30天,SDPP组血清总超氧化物歧化酶(T⁃SOD)、谷胱甘肽过氧化物酶(GPx)和过氧化氢酶(CAT)活性显著升高(P<0.05),丙二醛(MDA)含量显著降低(P<0.05),而SIPP组上述指标均无显著变化(P>0.05);在试验第60天,SDPP组和SIPP组血清T⁃SOD、GPx和CAT活性均显著升高(P<0.05),MDA含量显著降低(P<0.05);3)在试验第30天,SDPP显著提高了血清免疫球蛋白G(IgG)、白细胞介素-1β(IL⁃1β)和白细胞介素-2(IL⁃2)含量(P<0.05);在试验第60天,SDPP和SIPP均显著提高了血清IgG含量(P<0.05),此外,SDPP显著提高了血清IL⁃1β、IL⁃2和肿瘤坏死因子-α(TNF⁃α)含量(P<0.05),而SIPP仅显著提高了血清IL⁃1β含量(P<0.05);4)在基因表达方面,在试验第30天,SDPP显著上调了白细胞中SOD1、GPx1、GPx4、CAT、核转录因子2(Nrf2)、IL⁃1β、和IL⁃2基因相对表达量(P<0.05);在试验第60天,SDPP组白细胞中SOD1、CAT、GPx4、IL⁃1β和IL⁃2基因相对表达量显著提高(P<0.05),SIPP组白细胞中SOD1、GPx1、CAT、IL⁃1β和IL⁃2基因相对表达量显著提高(P<0.05)。上述结果表明,持续短光照能分泌更多的MLT,提高山羊的免疫和抗氧化功能。 相似文献

The effect of dietary methionine (Met) levels on endogenous N and amino acids (AA) flows at different part of the digestive tract of growing goats was determined using a 15N isotope dilution technique. Three goats (25 ± 2.5 kg) were fitted with the ruminal, duodenal and ileal cannulae and allocated to three dietary treatments in a 3 × 3 Latin square design. The dietary treatments consisted of a total mixed ration containing three levels of Met (0.15%, 0.25% and 0.35%) respectively. It was found that at 0.15% Met level, the lowest flow in endogenous N and total AA at the duodenum and ileum occurred. The endogenous N secretion contributed to 26% and 23% of the duodenal and ileal total N flows, respectively, and the proportions were not affected by the dietary Met levels. The duodenal and ileal flows of endogenous total AA were 11.1, 11.8, 11.3 g/d and 2.9, 3.9, 4.1 g/d respectively. The average real digestibility of N was 65%, 87% and 95% in the forestomach, intestine and whole digestive tract respectively. 相似文献
