羟基蛋氨酸螯合铜对断奶仔猪和育肥猪生长性能及组织铜含量的影响

文章旨在评估日粮添加有机铜(羟基蛋氨酸铜)及不同铜源和添加水平对仔猪和育肥猪生长性能及组织铜含量的影响。本研究共分为3个试验,试验1评估日粮添加6和170 mg/kg硫酸铜及170 mg/kg羟基蛋氨酸铜对1~42 d断奶仔猪生长性能和组织铜含量的影响。试验2评估日粮不同铜源对1~21 d仔猪生长性能和肝脏微量元素含量的影响。试验3评估日粮不同铜源对育肥猪屠宰性能的影响。与对照组和硫酸铜组相比,羟基蛋氨酸铜组仔猪末重均提高6%(P0.05)。与硫酸铜组相比,羟基蛋氨酸铜组1~14 d仔猪日增重和日采食量分别提高了22.9%和8.6%(P0.05),同时显著降低了料比(P0.05)。硫酸铜组肝脏铜含量较对照组提高了2.7倍(P0.05),较羟基蛋氨酸铜组提高了4.5倍(P0.05)。羟基蛋氨酸铜组较对照组和碱铜组显著提高了肝脏铜含量(P0.05)。80 mg/kg羟基蛋氨酸铜组较对照组和160 mg/kg硫酸铜组显著提高了育肥猪屠体重(P0.05)。80和160 mg/kg羟基蛋氨酸铜较160 mg/kg硫酸铜和对照组显著提高了眼肌深度(P0.05)。综上所述,羟基蛋氨酸铜可以提高仔猪的生长性能和肝脏铜含量,但对仔猪促生长作用所需的添加量较硫酸铜小。80 mg/kg羟基蛋氨酸铜可以提高育肥猪生长性能和眼肌深度。

蛋氨酸铜对肉鸡生长性能及某些生理生化指标的影响

选择1日龄健康AA肉仔鸡120只,随机分成4组,使用蛋氨酸铜作为铜源,对照组基础日粮铜含量为11 mg/kg,3个试验组日粮中铜含量分别为110 mg/kg、220 mg/kg和330 mg/kg,各试验组肉仔鸡均饲喂添加蛋氨酸铜的玉米一豆饼型日粮至60日龄结束试验.在12,24,36,48,60日龄称量各组鸡体重并计算出36,60日龄时的料肉比;在12,36,60日龄采血,进行红细胞数、血红蛋白含量及血清GH、T3、T4水平的测定.结果表明:与对照组相比,日粮中含铜110 mg/kg、220 mg/kg和330 mg/kg对雏鸡生长有明显的促进作用(P<0.05),料肉比稍有提高,但与对照组差异不显著(P>0.05);血液红细胞数和血红蛋白含量都在正常范围内,没有出现异常减少;高铜(110 mg/kg、220 mg/kg和330 mg/kg)组鸡血清GH水平均低于对照组,而T3、T4浓度均显著高于对照组(P<0.05).结果说明高铜可促进肉鸡生长,影响血清中与生长有关的激素水平.     

不同铜源对仔猪生长性能、腹泻率及血清免疫和抗氧化功能的影响

试验旨在研究日粮中添加不同铜源(柠檬酸铜、硫酸铜或碱式氯化铜)对仔猪生长性能、腹泻率及血清免疫和抗氧化功能的影响。选用21日龄断奶、健康、平均体重(6.41±0.32)kg的杜×长×大仔猪64头,按单因素试验设计原则,随机分为4个处理,每个处理4个重复,每个重复4头猪(公、母各半)。对照组不额外添加铜,试验在基础日粮中分别添加90 mg/kg硫酸铜、90 mg/kg碱式氯化铜或90 mg/kg柠檬酸铜(均以铜计)。预试期3 d,正试期28 d。结果表明:与对照组相比,添加柠檬酸铜组仔猪平均日增重提高了25.89%(P0.05),仔猪腹泻率降低了66.79%(P0.05),仔猪血清丙二醛含量降低了21.38%(P0.05);但仔猪平均日采食量、耗料增重比、血清IgA、IgG、IgM和铜蓝蛋白含量均无显著差异(P0.05);与对照组相比,添加硫酸铜或碱式氯化铜对仔猪生长性能、腹泻率及血清免疫和抗氧化指标均无显著影响(P0.05);与硫酸铜组和碱式氯化铜组相比,添加柠檬酸铜使仔猪腹泻率降低66.79%和63.82%(P0.05),但对仔猪生长性能及血清免疫和抗氧化指标无显著影响(P0.05)。综上,在仔猪日粮中添加90 mg/kg柠檬酸铜可以提高平均日增重、降低腹泻率和降低血清丙二醛含量。     

日粮补充不同来源的锌和铜对仔猪生长性能和血清参数的影响

文章旨在研究日粮补充不同来源的锌和铜对仔猪生长性能和血清参数的影响。试验将90头21日龄断奶仔猪随机分成3个试验组,每组10个重复。对照组饲喂基础日粮,试验1组在基础日粮中饲喂150 mg/kg硫酸铜+150 mg/kg硫酸锌,试验2组在基础日粮中饲喂150 mg/kg蛋氨酸铜+150 mg/kg蛋氨酸锌,预试期2 d、正试期14 d。试验结果,与对照组相比,在终末体重、日平均采食量与日平均增重上,试验1组、试验2组更高（P＜0.05）,F/G均显著低于对照组（P＜0.05）,试验2组F/G较试验1组显著降低（P＜0.05）|与对照组相比,试验1组、试验2组血清SOD活性、GSH活性、Zn水平、IgG含量较对照组显著提高（P＜0.05）,MDA含量、UN水平较对照组显著降低（P＜0.05）。结论,相较于硫酸锌、硫酸铜的补充,日粮补充蛋氨酸锌与蛋氨酸铜更有利于促进仔猪生长,改善血清抗氧化酶活性,提高机体免疫力。 [关键词]仔猪|蛋氨酸铜|蛋氨酸锌|生长性能|血清参数     

高铜对雏鸡脑组织一氧化氦含量和一氧化氮合酶活性的影响

1日龄艾维菌肉鸡健雏360羽,随机分为6组,分别喂以对照组日粮(10.89 mg/kg Cu)和高铜日粮(100 mg/kg Cu,高铜Ⅰ组;200 mg/kg Cu,高铜Ⅱ组;400 mg/kg Cu,高铜Ⅲ组;600 mg/kg Cu,高铜Ⅳ组;800 mg/kg Cu,高铜Ⅴ组)6周,观察高铜对雏鸡脑组织和血清一氧化氮(N0)含量及一氧化氮合酶(NOS)活性变化的影响,探讨高铜对雏鸡脑组织的损伤机理.高铜Ⅱ、Ⅲ、Ⅳ和Ⅴ组脑组织和血清NO的含量较对照组显著或极显著升高(P<0.05或P<0.01).NOS的活性随日粮铜含量的升高而升高,各高铜组脑组织NOS的活性较对照组极显著升高(P<0.01);高铜Ⅱ、Ⅲ、Ⅳ和Ⅴ组血清NOS的活性较对照组显著或极显著升高(P<0.05或P<0.01).日粮铜水平在200 mg/kg及以上时,脑组织和血清NO的含量和NOS的活性随日粮铜的含量升高而升高,脑组织因氧化而受损.     

白术、微米白术和白术多糖对断奶仔猪生长性能和肠道形态及微生态区系的影响

Prevalence and seasonal incidence of nematode parasites and fluke infections of sheep and goats in eastern Ethiopia

Sissay, M.M., Uggla, A. and Waller, P.J., XXXX. Prevalence and seasonal incidence of nematode parasites and fluke infections of sheep and goats in eastern Ethiopia. Tropical Animal Health and Production, XXXX. A 2-year abattoir survey was carried out to determine the prevalence, abundance and seasonal incidence of gastro-intestinal (GI) nematodes and trematodes (flukes) of sheep and goats in the semi-arid zone of eastern Ethiopia. During May 2003 to April 2005, viscera including liver, lungs and GI tracts were collected from 655 sheep and 632 goats slaughtered at 4 abattoirs located in the towns of Haramaya, Harar, Dire Dawa and Jijiga in eastern Ethiopia. All animals were raised in the farming areas located within the community boundaries for each town. Collected materials were transported within 24 h to the parasitology laboratory of Haramaya University for immediate processing. Thirteen species belonging to 9 genera of GI nematodes (Haemonchus contortus, Trichostrongylus axei, T. colubriformis, T. vitrinus, Nematodirus filicollis, N. spathiger, Oesophagostomum columbianum, O. venulosum, Strongyloides papillosus, Bunostomum trigonocephalum, Trichuris ovis, Cooperia curticei and Chabertia ovina), and 4 species belonging to 3 genera of trematodes (Fasciola hepatica, F. gigantica, Paramphistomum {Calicohoron} microbothrium and Dicrocoelium dendriticum) were recorded in both sheep and goats. All animals in this investigation were infected with multiple species to varying degrees. The mean burdens of adult nematodes were generally moderate in both sheep and goats and showed patterns of seasonal abundance that corresponded with the bi-modal annual rainfall pattern, with highest burdens around the middle of the rainy season. In both sheep and goats there were significant differences in the mean worm burdens and abundance of the different nematode species between the four geographic locations, with worm burdens in the Haramaya and Harar areas greater than those observed in the Dire Dawa and Jijiga locations. Similar seasonal variations were also observed in the prevalence of flukes. But there were no significant differences in the prevalence of each fluke species between the four locations. Overall, the results showed that Haemonchus, Trichostrongylus, Nematodirus, Oesophagostomum, Fasciola and Paramphistomum species were the most abundant helminth parasites of sheep and goats in eastern Ethiopia.     

Phase I evaluation of CCNU (lomustine) in tumor-bearing cats

1-(2-Chloroethyl)3-cyclohexyl-1-nitrosourea (CCNU) is an alkylating agent in the nitrosourea subclass. A prospective evaluation of CCNU was done to determine the maximally tolerated dosage of CCNU in tumor-bearing cats. Response data were obtained when available. Twenty-five cats were treated with CCNU at a dosage of 50-60 mg/m3 body surface area. Complete hematologic data were available for 13 cats. Neutropenia was the acute dose-limiting toxicity. The median neutrophil count at the nadir was 1,000 cells/microL (mean, 2,433 cells/microL; range, 0-9,694 cells/microL). The time of neutrophil nadir was variable, occurring 7-28 days after treatment, and counts sometimes did not return to normal for up to 14 days after the nadir. Based on these findings, a 6-week dosing interval and weekly hematologic monitoring after the 1st treatment with CCNU are recommended. The nadir of the platelet count may occur 14-21 days after treatment. The median platelet count at the nadir was 43,500 cells/microL. No gastrointestinal, renal, or hepatic toxicities were observed after a single CCNU treatment, and additional studies to evaluate the potential for cumulative toxicity should be performed. Five cats with lymphoma and 1 cat with mast cell tumor had measurable responses to CCNU. Phase II studies to evaluate antitumor activity should be completed with a dosing regimen of 50-60 mg/m3 every 6 weeks.     

Prevalence of gastric lesions in racing Alaskan sled dogs

Human and equine athletes are reported to have a high prevalence of gastric disease, and anecdotal evidence suggests a similar phenomenon applies to racing sled dogs. To investigate the prevalence of gastric disease in racing sled dogs, we conducted 2 gastroscopy studies on dogs competing in the annual Iditarod Sled Dog Race. A pilot study of dogs that were either dropped from the 2000 Iditarod Sled Dog Race because of illness or that finished the race indicated that, approximately 5 days after competing, 10 of 28 dogs (35%) had endoscopic evidence of gastric ulceration, erosion, or hemorrhage. The next year, an endoscopic study of 73 dogs participating in the 2001 Iditarod race was performed in order to evaluate a larger population of dogs. Data from 70 of these dogs could be used; 34 (48.5%) had ulceration, erosion, gastric hemorrhage, or some combination of these findings. When this group of 70 dogs was compared retrospectively to a control group of 87 dogs presented to the Texas A&M University (TAMU) Veterinary Medical Teaching Hospital, the Iditarod sled dogs had a significantly higher prevalence (P = .049) of gastric lesions. These findings suggest that, similar to athletes of other species, elite canine athletes have an increased prevalence of gastric disease compared to the canine population at large.     

Furosemide continuous rate infusion in the horse: evaluation of enhanced efficacy and reduced side effects

Continuous rate infusion (CRI) of furosemide in humans is considered superior to intermittent administration (IA). This study examined whether furosemide CRI, compared with IA, would increase diuretic efficacy with decreased fluid and electrolyte fluctuations and activation of the renin-angiotensin-aldosterone system (RAAS) in the horse. Five mares were used in a crossover-design study. During a 24-hour period, each horse received a total of 3 mg/kg furosemide by either CRI (0.12 mg/kg/h preceded by a loading dose of 0.12 mg/kg IV) or IA (1 mg/kg IV q8h). There was not a statistically significant difference in urine volume over 24 hours between methods; however, urine volume was significantly greater after CRI compared with IA during the first 8 hours ([median 25th percentile, 75th percentile]: 9.6 L [8.9, 14.4] for CRI versus 5.9 L [5.3, 6.0] for IA). CRI produced a more uniform urine flow, decreased fluctuations in plasma volume, and suppressed renal concentrating ability throughout the infusion period. Potassium, Ca, and Cl excretion was greater during CRI than IA (1,133 mmol [1.110, 1,229] versus 764 mmol [709, 904], 102.7 mmol [96.0, 117.2] versus 73.3 mmol [65.0, 73.5], and 1,776 mmol [1,657, 2.378] versus 1,596 mmol [1,457, 1,767], respectively). Elimination half-lives of furosemide were 1.35 and 0.47 hours for CRI and IA, respectively. The area under the excretion rate curve was 1,285.7 and 184.2 mL x mg/mL for CRI and IA, respectively. Furosemide CRI (0.12 mg/kg/h) for 8 hours, preceded by a loading dose (0.12 mg/kg), is recommended when profound diuresis is needed acutely in horses.     

Y‐chromosomal variation of local goat breeds of Turkey close to the domestication centre

Genetic variations in chromosome Y are enabling researchers to identify paternal lineages, which are informative for introgressions and migrations. In this study, the male‐specific region markers, sex‐determining region‐Y (SRY), amelogenin (AMELY) and zinc finger (ZFY) were analysed in seven Turkish native goat breeds, Angora, Kilis, Hair, Honaml?, Norduz, Gürcü and Abaza. A SNP in the ZFY gene defined a new haplotype Y2C. All domestic haplogroups originate from Capra aegagrus, while the finding of Y1A, Y1B, Y2A and Y2C in 32, 4, 126 and 2 Turkish domestic goats, respectively, appears to indicate a predomestic origin of the major haplotypes. The occurrence of four haplotypes in the Hair goat and, in contrast, a frequency of 96% of Y1A in the Kilis breed illustrate that Y‐chromosomal variants have a more breed‐dependent distribution than mitochondrial or autosomal DNA. This probably reflects male founder effects, but a role in adaptation cannot be excluded.     

The Epidemiology of Gastrointestinal Nematodes of Dairy Cattle in Central Kenya

The epidemiology of H. placei and of other gastrointestinal nematodes in yearling dairy cattle was examined on two farms in Kiambu District, central Kenya during each of 13 one-month periods from April 1993 to April 1994. On each farm, 32 newly weaned dairy calves were given a single dose of albendazole and then placed on experimental pastures. Twelve of the animals were designated for bi-monthly slaughter (n = 2) and analysis of worm population characteristics and 20 were designated for blood and faecal collection and for weighing. Two parasite-free tracer calves were grazed alongside the weaner calves each month throughout the study period and were also slaughtered for analysis of worm populations. Faecal egg counts, haematological and serum pepsinogen determinations, herbage larval counts, and animal live weight changes were recorded monthly. The study revealed that Haemonchus placei, Trichostrongylus axei, Cooperia spp. and Oesophagostomum radiatum were responsible for parasitic gastroenteritis and that H. placei was the predominant nematode present in the young cattle on both farms. Faecal egg counts from resident cattle and necropsy worm counts revealed that pasture larval levels were directly related to the amount of rainfall. The total worm burdens in the animals were highest during the rainy season (March–June and October–December) and lowest during the dry seasons (July–September and January–February). The very low recovery of immature larvae of H. placei from the tracer calves indicated that arrested development is not a feature of the life cycle of this parasite in central Kenya. The maintenance of the parasite population depended on continuous cycling of infection between the host and the pasture. The agroclimatic conditions of the study area were such that, in general, favourable weather conditions for the development and survival of the free-living stages of gastrointestinal nematodes existed all year round.     

Diversity of Ectoparasites in Sheep Flocks in Sa~o Paulo,Brazil

The occurrence of ectoparasites in sheep flocks is frequently reported but seldom quantified. Sheep production used to be a predominantly family activity in the state of Sa~o Paulo (Brazil), but it began to become a commercial activity in the past decade. Thus, information about the ectoparasites existing in sheep flocks has become necessary. The present data were obtained by means of questionnaires sent to all sheep breeders belonging to the `Associaça~o Paulista de Criadores de Ovinos' (ASPACO; Sa~o Paulo State Association of Sheep Breeders). Response reliability was tested by means of random visits paid to 10.6% of the respondents. Most of the properties (89.5%) reported the presence of one or more ectoparasites. Screw-worm (Cochliomyia hominivorax) was the most frequent ectoparasite (72.5%), followed by bot fly larvae (Dermatobia hominis, 45.0%), ticks (Amblyomma cajennense) and Boophilus microplus, 31.3%) and finally lice (Damalinia ovis, 13.8%). Combined infestations also occurred, the most common one being screw-worm with bot fly larvae (36.0%) followed by bot fly larvae with ticks (13.9%), screw-worm with ticks (9.3%), bot fly larvae with lice (6.9%), and ticks with lice (5.0%). The most common triple combination was screw-worm, bot fly larvae and ticks (12.8%). Breeds raised for meat or wool were attacked by bot fly larvae and ticks more often than other breeds. Lice were only absent from animals of indigenous breeds. The relationships among these ectoparasites are discussed in terms of sheep breeds, flock size, seasonality and the ectoparasitic combinations on the host.     

Feline intracranial neoplasia: retrospective review of 160 cases (1985-2001)

The purpose of this study was to determine the frequency of different tumor types within a large cohort of cats with intracranial neoplasia and to attempt to correlate signalment, tumor size and location, and survival time for each tumor. Medical records of 160 cats with confirmed intracranial neoplasia evaluated between 1985 and 2001 were reviewed. Parameters evaluated included age, sex, breed, FeLV/FIV status, clinical signs, duration of signs, number of tumors, tumor location(s), imaging results, treatment, survival times, and histopathologic diagnosis. Most of the cats were older (11.3 +/- 3.8 years). Primary tumors accounted for 70.6% of cases. Metastasis and direct extension of secondary tumors accounted for only 5.6 and 3.8% of cases, respectively. Twelve cats (7.5%) had 2 or more discrete tumors of the same type, whereas 16 cats (10.0%) had 2 different types of intracranial tumors. The most common tumor types were meningioma (n = 93, 58.1%), lymphoma (n = 23, 14.4%), pituitary tumors (n = 14, 8.8%), and gliomas (n = 12, 7.5%). The most common neurological signs were altered consciousness (n = 42, 26.2%), circling (n = 36, 22.5%), and seizures (n = 36, 22.5%). Cats without specific neurological signs were common (n = 34, 21.2%). The tumor was considered an incidental finding in 30 (18.8%) cats. In addition to expected relationships (eg, meninges and meningioma, pituitary and pituitary tumors), we found that lesion location was predictive of tumor type with diffuse cerebral or brainstem involvement predictive of lymphoma and third ventricle involvement predictive of meningioma.
