人工养狗是21世纪的新兴特养项目,由于狍子相对于兔、猪、狗、狐等动物,繁殖率较低、种狍奇缺、严重制约了人工养狗业向产业化方向发展。因此,在野狍资源较丰富的地区,有计划地开展野狍人工驯化工作,变野狍为家养狗,不失为扩充种狍后备资源的一项良策。但是人工驯化野狍难度较大,猎捕野狍的人都知道“狍子气大,自己就气死了”。说的是 相似文献

1 野狍的特点 野狍俗称狍子，学名矮鹿，属双蹄目鹿科动物，现为国家野生保护动物。近年来产区不法分子过度偷猎，使野生资源非常稀少。野狍家养的成功，不仅有利于保持野生资源，也为我国广大城乡探索出一条新的致富之路。 野狍素有“草上飞”之称。它反应敏捷，行动迅速，性情活泼，胆小易惊，喜欢群居。野狍体形匀称，体质健壮，适应性和抗病力极强，且易驯化、好管理，食物来源广泛，各种阔叶树叶、野生杂草、农作物秸秆、水果皮、蔬菜等都是野狍喜食的饲料。2 饲养管理 饲养野狍要做好以下三方面工作： （1）建圈舍。狍圈一般建在庭院… 相似文献

狍的生物学特性与科学驯养 总被引：1，自引：0，他引：1
狍又名矮鹿、野狍、野羊 ,是小型鹿科动物 ,广泛分布于欧亚大陆的中部和北部 ,黑龙江、吉林、辽宁、陕西、河北、青海和甘肃等省区是我国狍的主要产区。由于野狍适应性和抗病性强 ,食性广泛 ,易人工驯养。同时由于养殖周期短 ,饲养成本低 ,经济效益高 ,野狍已成为农民脱贫致富的养殖新秀。因此 ,推广科学规范的野狍驯养技术 ,对科学保护和合理开发利用我国野狍资源 ,促进我国特种养殖业健康发展均具有极重要的现实意义。1 狍的生物学特性1 1 狍的形态特征成年狍体长 95～ 1 4 0ｃｍ ,体高 6 5～95ｃｍ ,体重 2 5～ 4 5ｋｇ。其中西北亚种… 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献

以国际标准强毒Ｒ株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离ＭＧ,并收集感染鸡所产蛋分离ＭＧ。结果表明,人工感染４８小时后上、下呼吸道及肺已被全面感染,９６小时气囊已被感染,１２０小时输卵管已能分离到ＭＧ,卵巢始终分离不到ＭＧ。人工感染鸡自１４４小时便能在其所产蛋中分离出ＭＧ。药物治疗能在７２小时内消除感染,油乳剂苗则需２４天后逐渐降低蛋内ＭＧ分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内ＭＧ,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献
