盈江土地肥沃,气候宜人,雨量充沛,资源丰富,具有发展山羊养殖的优越条件,养羊业也是现代畜牧业的重要组成部分,是山区农民增收的重要来源,2012年9月止,盈江县山羊存栏27 003只,肉产量153吨.长期以来寄生虫病制约着养羊业的发展,特别是球虫病往往被忽视,而球虫病是山羊常见的一种寄生虫病,山羊球虫病的病原体为艾美尔科艾美尔属的原虫,主要感染1～3月龄羊羔,成年羊也感染但症状不明显.山羊球虫病的主要特征表现为粪不成形或拉稀,食欲下降,生长发育不良,严重时高度贫血,衰竭而死亡.
1 流行病学
球虫病的传染源是病羊和带虫羊,虫卵随粪便排到外界,污染了牧地、牧草、饲料、饮水、用具和环境,经消化道使健康的羊被感染.据观察无论什么品种及各种年龄的山羊对球虫病均易感染,但1～3月龄的羊羔发病率和死亡率较高,发病率高达100％,死亡率在50％以上.成年山羊感染率也相当高,但不发病或很少发病,仅为带虫者,成为病源的主要传播源. 相似文献

Decoquinate was evaluated as a coccidiostat in domestic goats. Fifty goats less than 4 months of age were assigned to 5 groups (pens) of 10 goats each and were treated for 87 days with 0 (control), 0.3, 0.5, 1.0, or 4.0 mg of decoquinate in feed/kg of body weight. Goats were inoculated orally weight. Goats were inoculated orally with 30,000 oocysts, mainly Eimeria christenseni (74%) and E ninakohlyakimovae (20%) on day 19. Nontreated goats developed profuse watery diarrhea and tenesmus and gained weight poorly; 2 died. Treated goats did not develop clinical coccidiosis and gained significantly more weight (P less than 0.05), regardless of the dose used. Treated goats also had significantly fewer (P less than 0.05) oocysts in feces than did nontreated controls. Oocyst numbers were inversely related to dose; a more rapid decrease in oocyst numbers occurred as the dose was increased. At the doses used, decoquinate was safe in goats and was an effective drug for the prevention of clinical coccidiosis. 相似文献

Fifty, 2–3 month old dairy goats were each vaccinated orally with 10000 sporocysts of Sarcocystis capracanis and 25 age-matched goats served as uninoculated controls. Groups of vaccinated and control goats were challenged with lethal doses of S. capracanis at 95, 113, 205, and 274 days post-vaccination. Vaccinated goats developed subclinical sarcocystosis. Twenty-three vaccinated goats and 1 control goat died of intestinal coccidiosis and bacterial pneumonia, 15–118 days after vaccination. Myositis and degenerating sarcocysts were seen in muscles of goats necropsied at 90–186 days postvaccination. Very few, or no sarcocysts were seen in goats necropsied at 272 and 332 days post-vaccination. Vaccinated goats survived a lethal challenge inoculation indicating persistent protective immunity. 相似文献

Ponazuril (toltrazuril sulfone) is a triazine antiprotozoal agent that targets apicomplexan organisms. Ponazuril may have clinical application in the treatment of clinical coccidiosis due to Eimeria species in goats, along with other protozoal infections. To evaluate the absorption, distribution and elimination characteristics of ponazuril in goats, a sensitive, validated high‐pressure liquid chromatography and mass spectroscopy method for ponazuril in caprine plasma was developed. After a single oral dose of ponazuril at 10 mg/kg, plasma samples from seven weanling goats were collected and assayed. Plasma concentrations of ponazuril in the goats peaked at 36 ± 13 h post drug administration at a concentration of 9 ± 2 μg/mL. Concentrations declined to an average of 4.2 ± 0.8 μg/mL after 168 h with an average elimination half‐life of 129 ± 72 h post drug administration. This study shows that ponazuril is relatively well absorbed after a single oral dose in goats. Efficacy trials are underway to determine clinical efficacy of ponazuril in the treatment of clinical coccidiosis in goats at 10 mg/kg dosage. 相似文献

The protozoan diseases, coccidiosis and cryptosporidiosis, are important enteric diseases of sheep and goats, resulting in diarrhea, inefficient weight gains, and occasionally death. Coccidiosis is a widespread, serious economic disease affecting animals who are preweaned, recently weaned, or in unsanitary, stressful, or crowded conditions, as well as after entering feedlots. The Eimeria species in sheep and goats are relatively host specific. Control is accomplished through sanitation and by incorporating one of the modern coccidiostats, such as lasalocid or decoquinate, in feed or salt to ensure an intake of approximately 1 mg of drug per kg of body weight per day for at least 30 consecutive days. Prevention and control of coccidiosis results in significantly greater weight gains and production, whereas disease with or without treatment is likely to result in inefficient production and economic loss to the producer. Cryptosporidiosis, caused by Cryptosporidium parvum, is primarily a disease of lambs and kids less than 30 days of age and is usually a milder disease than coccidiosis. Infective oocysts are passed in feces and are transmitted by oral ingestion. Oocysts readily infect a variety of animals, including humans. Cryptosporidiosis is a prevalent disease in neonatal ruminants and in humans. Effective treatments are not available, but because the disease is usually mild and self-limited, supportive care, primarily hydration, is important. Control is strict sanitation and quarantine of sick animals. Disinfection of contaminated housing with ammonia or formalin will kill the oocysts. The cyst-forming coccidia diseases, toxoplasmosis and sarcocystosis, utilize two hosts in their life cycles: sheep or goats and carnivores. Abortions and reproductive failures are major manifestations of disease. Control is through elimination of carnivore feces from the premises through management. 相似文献

OBJECTIVE: To evaluate signalment, history, clinical and pathologic findings, and seasonal weather patterns in association with fatal gastrointestinal parasitism in goats. DESIGN: Retrospective case series. ANIMALS: 152 goats that were > 1 day of age. PROCEDURES: Characteristics including age and counts of coccidia oocysts and trichostrongyle ova (eggs) per gram of feces (EPG) in goats that died because of gastrointestinal parasitism and goats that died because of other causes were compared. Weather data and annual incidence of caprine fatal gastrointestinal parasitism were investigated. RESULTS: Death was attributed to gastrointestinal parasitism in 31 of 152 (20%) goats (median age, 5 months; range, 1 month to 7 years); deaths were attributed to coccidiosis (n = 7 goats; median age, 4 months; median EPG, 2,225), trichostrongylosis (6 goats; median age, 1.25 years; median EPG, 3,700), or dual infection (18 goats; median age, 6.7 months; median EPG, 8,088 coccidia and 5,475 trichostrongyles). Sudden onset of weakness or death was a common historical finding; diarrhea was evident in 15 goats. Common postmortem findings in these goats included cachexia, tissue pallor, poorly formed feces, and mesenteric lymphadenomegaly. Wet weather in spring and summer was associated with increased annual incidence of fatal gastrointestinal parasitism in goats. CONCLUSIONS AND CLINICAL RELEVANCE: Gastrointestinal parasitism is an important cause of death in goats. Clinical signs may not develop until just prior to death, and diagnosis is achieved via parasitologic evaluation of feces and necropsy. Seasonal weather patterns should be considered on an annual basis when designing parasite control programs for goats. 相似文献

Diversity and seasonal occurrence of coccidia in a communally reared mixed flock of sheep and goats at Mafikeng, North West Province, South Africa, was determined between March 2008 and February 2009. Faecal specimens were collected directly from the rectum of the animals and the number of oocysts per gram of faeces (opg) determined. The mean monthly opg for goats was significantly higher than that for sheep. Higher oocyst counts were observed during the hot, rainy season than during the cold, dry season. The highest mean values for both the sheep (862.5 opg) and goats (1200 opg) were recorded during March. Six species (Eimeria crandallis, E. bakuensis, E. weybridgensis, E. ahsata, E. intricata, and E. ovinoidalis) were recovered from sheep, with E. crandallis and E. bakuensis occurring most frequently. The last 2 species, together with E. ahsata, are considered among the most pathogenic species in sheep. In goats, 7 species (E. arloingi, E. jolchijevi, E. caprina, E. alijevi, E. caprovina, E. christenseni and E. hirci) were recovered, with E. arloingi and E. jolchijevi occurring most frequently. Up to 5 Eimeria species were recovered from individual specimens in goats while up to 4 were recovered in sheep. No cross-infections between goats and sheep were recorded and no clinical coccidiosis was noted during the study. It is increasingly becoming evident that the pathogenic E. arloingi is one of the most commonly occurring Eimeria species in goats in South Africa. 相似文献

The study was carried out in a flock consisting of 110 goats. Nine species of coccidia were found: Eimeria christenseni, E. arloingi, E. jolchijev, E. ninakohlyakimovae, E. alijevi, E. apsheronica, E. caprina, E. caprovina and E. hirci. Eighty-one percent of adults and 100% of kids were infected. Number of oocysts per gram of feces in kids ranged form 1200 to 202000. Clinical symptoms in about 50% of kids were observed. Toltrazuril (Baycox, Bayer), 20 mg/kg of body weight was highly efficacious in therapy of goat coccidiosis. 相似文献
