Studies on the Haematology and Trace Element Status of Adult Bactrian Camels (Camelus bactrianus) in China     

Zongping L 《Veterinary research communications》2003,27(5):397-405

Reference values were established for some haematological and serum biochemical constituents in Bactrian camels (Camelus bactrianus) in China. The contents of seven trace elements in the blood, hair, liver, kidney, heart, spleen, lung, cerebrum, cerebellum, rib, ovary, pancreas and gluteal muscle of Bactrian camels were also measured. Some of these values are reported for the first time for Bactrian camels in China. Most haematological and serum biochemical values were similar to those of cattle, yaks, sheep and dromedary camels, but the mean serum albumin concentration and the albumim/globulin ratio were significantly higher than those in other ruminants and the mean thyroxine concentration was half that in dromedary camels. The liver contained the highest concentrations of copper, zinc, manganese and iron, and the renal cortex contained the highest concentration of selenium. The concentrations of selenium, cobalt, zinc, manganese and molybdenum in the tissues were within the reference ranges for other ruminants, but the mean iron and copper concentrations in the liver were significantly higher than those in other ruminants.  相似文献   

The Arterial Supply to the Eye of the Bactrian Camel (Camelus bactrianus)   总被引：1，自引：0，他引：1  

Wang JL 《Veterinary research communications》2002,26(7):505-512

The arterial supply to the eye of the bactrian camel (Camelus bactrianus) was studied by gross dissection. The supply came from the external ophthalmic, external ethmoidal and malar and maxillary tubercular arteries, ophthalmic rete mirabile, and the rostral epidural rete mirabile. The external ophthalmic artery gave rise to branches to supply the dorsal oblique muscle, lacrimal gland, superior and inferior eyelids, and the lateral angle of the eye, and to take part in the formation of the rostral epidural rete and the ophthalmic rete mirabile. The external ethmoidal artery detached off some branches to supply the ventral and medial dorsal rectus oblique muscles, the conjunctiva of the superior eyelid and the fat body of the orbit. The branches of the malar artery supplied the inferior, superior and third eyelids, ventral oblique muscle, and the medial angle of the eye. The ophthalmic rete mirabile gave off many branches to supply the rectus muscles of the eye, dorsal oblique and retractor oculi muscles, levator muscle of the superior eyelid, and the choroid.  相似文献

双峰驼红细胞的形态与特性研究     

陈怀涛  任安华 《畜牧兽医学报》1996,27(2):171-177

用光镜、电镜与血常规检查法研究了我国２８峰双峰鸵红细胞的形态特征和生物特性。这些动物的红细胞呈椭圆形，很薄，其边缘看来光滑，但在胞浆膜上有些小突起。经测定，红细胞平均体积（ＭＣＶ）较小（２３．９７±３．９５ｆｌ），但红细胞血红蛋白平均浓度（ＭＣＨＣ）比牛和马的高（３６．７５±５．１７ｇ％＞２７．６７±０．９６ｇ％或２８．４７±３．６５ｇ％，Ｐ＜０．０１）。同时双峰驼红细胞对渗透性溶解的抵抗力很强。作者发现，双峰驼红细胞在低渗透溶解前约可膨胀到原体积的１６０％。因此，红细胞在双峰驼体内的水－电解质代谢上有重要意义。  相似文献   

Potential of Pakistani camel for dairy and other uses     

Muhammad YAQOOB  Haq NAWAZ 《Animal Science Journal》2007,78(5):467-475

Camels have the potential for milk, meat and draught power and can contribute a handsome share of the production of these commodities. The potential of this wonderful animal has never been realized and it could be harnessed as a prospective milk producing animal. The future of animals that can thrive under harsh environmental conditions, the camel being at the top of the list, is bright. The camel is still a neglected species in Pakistan and has not received the proper attention of researchers and scientists. The population explosion, urbanization and industrialization have expanded agricultural activities to produce more food for the rapid growing human population of the country. Cultivated areas are shrinking, thus reducing the fodder production area for buffalo and cattle. Under these circumstances we have to search for other available sources to enhance milk production. The environmental changes occurring on the earth and the water shortage in the region have also adversely affected the production potential of buffalo, cattle, goats and sheep. Under these changing ecological circumstances, rearing camel is the best option for more milk production and the proper utilization of the vast unused lands of this country. Most studies also have named the camel as an animal of great socioeconomic importance in large tracts of the industrializing world. The camel serves as a cheaper source of power for drawing water from wells, plowing and leveling land, working mini extraction mills (extracting from oil seeds), grinding wheat, corn and other grains and crushing sugarcane and pulling carts for the transportation of goods as well as people.  相似文献   

Effect of Season on the Productivity of Camels (Camelus dromedarius and the Prevalence of Their Major Parasites in Eastern Ethiopia     

Zeleke M  Bekele T 《Tropical animal health and production》2001,33(4):321-329

The productivity and the prevalence rates of the major parasites of camels (Camelus dromedarius) kept under traditional management conditions at Errer valley, Ethiopia were assessed for a year (October 1997–September 1998). The daily milk offtake was significantly higher (p<0.05) during the wet season (3.12±0.03 L) than during the dry season (1.49±0.04 L). Likewise, significantly higher (p<0.05) daily weight gains (50.68±0.54 g) were observed during the wet season than during dry season in immature camels aged 1–4 years. Trypanosoma evansi, Sarcoptes scabiei and strongyle parasites were present throughout the year, but their prevalence rates were higher during the rainy months than during the dry months. The minimum and maximum point prevalence rates for T. evansi were 5.4% and 20.6%, respectively. Similarly, the point prevalence rates for S. scabiei also varied from 4.7% during the dry season to 21.7% during the rainy months. The highest strongyle egg counts per gram of faeces and highest point prevalence rate (85.7%) were observed in October, a rainy month, whereas the lowest number of eggs per gram of faeces and the lowest point prevalence rate (61.5%) were recorded in April, a dry month.  相似文献   

Preliminary Observations on the Concentrations of Serum Luteinizing Hormone and Follicle-stimulating Hormone during Gestation in Bactrian Camels (Camelus bactrianus)   总被引：1，自引：0，他引：1  

Zhao XX  Zhang Y  Chen BX 《Veterinary research communications》2001,25(2):153-160

The concentrations of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in the serum of the Bactrian camel (Camelus bactrianus) throughout pregnancy were analysed by radioimmunoassay. The samples were withdrawn at intervals of half a month. The serum LH concentrations varied significantly between 2.2±0.9 and 20.3±18.8 ng/ml during the pregnancy, with the highest value on the day of artificial insemination, which indicated that a preovulatory LH peak appeared. Thereafter, the LH concentration tended to fall, reaching a fairly constant low level by the eighth month of pregnancy. The serum FSH concentrations varied between 7.0±0.2 and 28.9±0.4 ng/ml during gestation, with the peak value being reached at 4.5 months, followed by a marked drop to 7.0±0.2 ng/ml at 7.5 months.  相似文献
