家畜的行为和生物学特性,有的取决于遗传,有的取决于后天的调教或使用。骡是公驴和母马交配所生的种间杂种,在体型和外貌上类似于驴的地方多,故在行为上与驴接近似的也多;但在生物特性上,因为它是杂种,有许作独特的地方。根据多年来各军马场繁殖军骡的经验,关于骡驹的行为与生物学特性有许多报道,现综合撰写于下,以供养骡者参考。一、记忆力很强根据养骡场的观察,从离乳到一岁半,虽经过一年的时间,远隔三、四十公里,仍能跑回原群找生母;有的虽已满2.5~3岁,如偶或遇见生母,仍能认识且表示恋母心情。因此,骡驹离乳,应远离母马群,善为 相似文献

新生骡驹溶血症是一种常见病,死亡率近100%,主要是幼骡吃亲母体初乳造成的。许多人主张骡驹生下后不让吃母奶,将奶弃掉。找奶姆或喂奶粉代哺乳,直至测定乳中凝集效价低了,再让其吃母奶。这样做不仅提高了育驹成本,还会使幼骡因得不到初乳的营养而影响发育。 相似文献

新生骡驹溶血病是初生仔驹吮食高效价抗体初乳后,表现以贫血、黄疸、血红蛋白尿为主要病症的急性免疫性贫血病。笔者应用凝集试验对85例新生骡驹进行了初生后哺初乳前的初乳——血液凝集反应预防性诊断,并对结果阳性、疑似反应的24例骡驹采取禁喂母马初乳,给人造乳,1至2天后再次同样诊断,结果转为阴性者改喂初乳的预防措施,收到良好效果,现报告如下。 相似文献

新生骡驹溶血病是初生仔驹吮食高效价抗体初乳后 ,表现以溶血黄疸、血红蛋白尿为主要病症的急性免疫性贫血病。本病在我国以新生骡驹多发。发病后目前多以停喂母马初乳、输血、补充造血物质为主的治疗方法 ,但治愈率不高。本研究采用新生骡驹的血液与哺乳母马的初乳进行平板凝集反应 ,以作为预防性诊断检查。对诊断结果阳性及可疑的骡驹采取禁喂母马初乳 ,喂给人造乳 ,1 -2天后再次同样诊断 ,结果转为阴性者改喂母马初乳。诊断检查结果阴性者准许哺母马初乳。应用这种预防性诊断方法 ,经过临床上对 86例新生骡驹的应用 ,结果表明效果良好。1… 相似文献

新生骡驹溶血病是危害新生骡驹最严重的疾病之一。自推广广州部队“初乳凝集效价测定”预测新生骡驹溶血病的方法后,我们试用“试管法”测定初乳凝集价218例,效果准确,在预防新生骡驹溶血病上起到了 相似文献

采用全天观察法,对京海黄鸡公鸡的性行为进行记录,获得京海黄鸡公鸡性行为的过程,总结京海黄鸡公鸡性行为规律,分析京海黄鸡公鸡个体间性行为的差异,并通过检测精液品质,研究京海黄鸡公鸡性行为与精液质量的关系;通过观察晴天与阴天时的性行为,分析不同的天气对京海黄鸡公鸡性行为的影响,结果显示:京海黄鸡性行为个体间差异不大,受天气的影响较为明显。本文通过对京海黄鸡公鸡性行为的观察研究,为进一步提高京海黄鸡公鸡自然交配的授精率和繁殖性能提供一定的科学依据。 相似文献

OBJECTIVE: To determine whether findings of urinalyses could be used to reliably distinguish gonadectomized cats with urine-marking behavior from those with no problem urination. DESIGN: Case control study. ANIMALS: 58 gonadectomized cats (47 males and 11 females) with urine-marking behavior (ie, marking of vertical surfaces) and 39 (26 males and 13 females) without problem urination or urinary tract-associated conditions. PROCEDURE: Urine was collected by cystocentesis from all cats. Findings of urinalyses of cats with urine-marking behavior were analyzed statistically for sex-related differences and differences between cats that marked vertical surfaces only and those that marked both vertical and horizontal surfaces; findings of urinalyses of control cats were compared between sexes. Subsequently, results of urinalyses of cats with urine-marking behavior were compared with those of control cats. RESULTS: With regard to variables measured via urinalysis, there were no differences between male and female cats within either group. Among cats with urine-marking behavior, there were no differences between those that only marked vertically and those that marked vertically and horizontally. Analyses of data from all cats with urine-marking behavior and control cats revealed no differences that could be associated with urine marking. CONCLUSIONS AND CLINICAL RELEVANCE: These data suggest that urine-marking behavior by gonadectomized cats is an aspect of normal behavior. Clinicians are advised to focus on behavioral history of house-soiling cats to differentiate between urine-marking behavior and inappropriate urination; for the latter, urinalysis is appropriate to rule out lower urinary tract disorders. 相似文献

Some of the techniques that may be used to study social, reproductive, and ingestive behavior in horses are described in this paper. One of the aspects of equine social behavior is the dominance hierarchy or patterns of agonistic behavior. Paired or group feeding from a single food source may be used to determine dominance hierarchies quickly. Focal animal studies of undisturbed groups of horses may also be used; this method takes longer, but may reveal affiliative as well as agonistic relationships among the horses. Reproductive behavior includes flehmen, the functional significance of which can be determined using combinations of field observations of harem groups and laboratory studies of stallions exposed to female urine or feces in the absence of the donor mare. Ingestive behavior may include food, salt, or water intake. Direct and indirect measurements of intake can be made and used to answer questions regarding the ability of horses to control their energy intake when the diet is diluted, the effect of feral equids on the ecology of an area, and the abilities of horses to compensate for dehydration and hypovolemia. 相似文献

Unsolicited reports of estrous behavior in mares thought to be pregnant were received from owners or caretakers of Arabian mares. Estrous behavior was confirmed and mares were examined for pregnancy. Gender of the conceptus was determined at foaling in 11 mares in which estrous behavior was confirmed while an apparently viable, ultrasonically normal-appearing conceptus was present. In 9 mares in which the day of ovulation was known (Day 0), the estrous behavior occurred on Day 12, 13 or 14 (5 mares), Day 18 or 20 (2 mares), Day 40 (1 mare) and Day 60 (1 mare). In another study, 55 pony mares were observed for estrous behavior every 3 days for 20 minutes during Days 11 to 40. Estrous behavior was observed in 1 mare (2%) on Day 24. Combined for the 2 studies, the incidence of a female conceptus (12/12) was greater (P<0.01) than the incidence of a male conceptus (0/12) in mares that exhibited estrous behavior. 相似文献

Resource managers continually attempt to influence stakeholder behavior to protect ecosystems. To aid managers and further our understanding of the human dimensions of natural resource management researchers have developed theories of pro-environmental behavior and to identify barriers to such behavior. However, there is a paucity of research integrating the two. There is a need to understand how perceived barriers influence the adoption of pro-environmental behaviors directly and how these barriers interact with the antecedents to pro-environmental behavior. Using the value-belief-norm theory as a guiding framework, we sought to fill this gap by investigating the effect of two barriers (lack of knowledge and low self-efficacy) among the antecedents to climate change–related behavior of anglers and other stakeholders (n = 324) living adjacent to Australia’s Great Barrier Reef. Results suggested that modeling/theorizing about how barriers fit into this process is complex because of differing contexts and levels of inclusion of barriers in existing theories. 相似文献
