Habitat use and locomotion of the François' langur (Trachypithecus francoisi) in limestone habitats of Nonggang,China

We collected data on habitat use and locomotion of the François' langur (Trachypithecus francoisi) between August 2003 and July 2004 at Nonggang Nature Reserve, China. A total of 739 h of behavioral data were collected during this study. We tested 2 predictions: (1) that the langurs may have special patterns of habitat use and locomotion adaptive to the limestone habitat, and (2) the langurs may exhibit different patterns of habitat use and locomotion among different zones of limestone hill. Our results indicated that François– langurs spent more time in the low‐risk, relatively food‐poor cliff–hilltop areas. When young leaves and fruit were scarce in the dry season, the langurs increased their time in the high‐risk, food‐rich valley basin. François– langurs were semi‐terrestrial, and leaping and climbing were their main locomotor modes. These behavioral patterns are considered to be related to characteristics of topography and vegetation in limestone habitat, such as large areas of cliff and discontinuous canopy. Our results also supported Prediction 2. The langurs confined locomotion to the main canopy and frequently adopted leaping while traveling in the hillside and valley basin. While traveling in cliff–hilltop areas, they tended to stay in the lower stratus (≤5 m) or move on the ground, and walking and climbing were their dominant traveling modes.

The influence of rearing conditions on the physical growth of captive Japanese macaques (Macaca fuscata)

To clarify the influence of rearing conditions on the growth of various body parts of Japanese macaques (Macaca fuscata), two groups reared under different conditions, i.e., a group born and reared in open enclosures (Enclosure group) and another consisting of macaques born and reared in cages (Caged group), were somatometrically analyzed. Somatometric data on 36 measures of various body parts were collected from 77 males and 92 females. Growth in many body parts was smaller in the Caged group than in the Enclosure group. Body parts that exhibited large incremental increases were more sensitive to differences in rearing space at the infantile growth stage in both sexes. Recovery from delayed growth at the pubertal growth stage was found in many body parts. However, the size of some locomotor elements such as the wrist and hand, and ankle and foot strongly reflected limitations of space and changes due to this were irreversible. Females were more sensitive than males to such differences in rearing conditions. We conclude that open enclosures with ample rearing space are necessary for the innate growth of Japanese macaques to occur.     

提高母羊产雌羔比例试验研究

新疆畜牧科学院研制生产的育肥素是一种内源激素和酶系统,对家畜进行生理调控,除了使畜体能快速增重外,还能提高牲畜胎儿的雌性比例.本研究课题正是利用育肥素这一综合功能开展对羔羊性别的研究. 1 目的及内容 适龄生产母畜在畜群中比例的高低是畜牧业能否快速发展的决定因素,因此大量增加母畜、提高适龄生产母畜的比例成为当前畜牧业快速发展的重要课题和途径之一.     

高原藏猪在亚热带环境生长发育和繁殖特性的比较研究

通过常规方法,对引入到广州地区的藏猪G1代进行了生长发育和繁殖指标的测定,包括G1代藏猪不同月龄的体重、体尺(体高、体长、胸围)值.测定母猪每胎产仔猪数、初生头重、离乳数和离乳率等.结果表明:藏猪繁殖力的各项指标高于原产地放牧藏猪猪群,而低于舍饲的藏猪猪群;雌雄藏猪体重相比较,除了1月龄有极显著性差异(P<0.01)和2月龄有显著差异(P<0.05)外,其余月龄雌雄之间均无差异;体尺值随月龄增长逐渐增加,不同性别之间,除6月龄体高雄性高于雌性外(P<0.05),其余月龄不同性别藏猪均无差异(P>0.05).说明经过2年的风土驯化,藏猪基本适应了亚热带气候环境,能够正常生长繁殖,并且保持了生长缓慢、小体型的特点,非常适合用于动物实验研究.     

日粮碳水化合物对幼龄反刍动物生长发育的影响

幼龄反刍动物胃肠道正处于发育阶段,微生物区系尚未完全建立且不稳定,容易受到日粮结构的影响,同时直接影响其后续的饲养管理。但目前这方面的数据缺乏,亟需开展研究。碳水化合物是日粮中重要的能源物质,为动物提供所需的大部分能量。本文从碳水化合物分类、瘤胃发育特点、非纤维性碳水化合物和纤维性碳水化合物及其适宜比例对幼龄反刍动物生长发育的影响几方面进行归纳总结,以期为幼龄反刍动物日粮合理配制提供理论依据。     

Effects of surgical implantation of temperature dataloggers on reproduction of captive striped skunks (Mephitis mephitis).

A total of 20 (14 females, six males) captive striped skunks (Mephitis mephitis) with miniature temperature dataloggers implanted free in the abdominal cavity were examined for reproductive performance and pathology because of implants. Eleven of 12 female skunks reproduced successfully 45.9+/-3.7 days after surgery to remove implanted dataloggers. The pregnancy rate of 91.7% (11/12) was much higher than other captive studies and was comparable with that of wild skunks. Eight striped skunks (six males, two females) that were euthanatized and necropsied after having implants in the abdominal cavity for 5 mo showed no apparent pathology associated with the implant. Implantation of the intraperitoneal devices did not lead to complications in abdominal tissues. Neither implant nor surgery affected reproduction. We conclude that implanted dataloggers can safely be used in physiologic studies of striped skunks or possibly other small carnivores in captive or field studies.     

大气CO2浓度升高对绿色型豌豆蚜生长发育和繁殖的影响

为了研究大气CO₂浓度升高对绿色型豌豆蚜生长发育和繁殖的影响,应用CO₂人工气候箱,CO₂浓度设置中等浓度[(550±27) μL/L]和高浓度[(750±37) μL/L],并以当前浓度[(375±18) μL/L]为对照,观察并记录了饲养在蚕豆上的连续3代绿色型豌豆蚜的生长发育和繁殖指标。结果表明,随着CO₂浓度升高,连续3代绿色型豌豆蚜发育历期均缩短,初产若蚜体重、成蚜体重、体质量差和相对日均体重增长率均呈增加趋势;各世代的繁殖期延长,平均产蚜量和最大产蚜量均增加;各世代的净增殖率(R₀)增大,平均世代周期(T)延长,内禀增长率(r_m)和周限增长率(λ)均减小。因此,绿色型豌豆蚜的种群数量随着CO₂浓度升高而下降,故推测未来大气CO₂浓度的升高可能不利于豌豆蚜的发生。
