猪群的健康检查

对猪进行定期健康检查时该作哪些项目,又该什么时候进行? 应该珍惜身体的健康,因为健康不会是永久的.每个养猪企业或迟或早都可能遇到疾病侵扰而发生经济损失.     

营销破茧——给用户一个购买借口

1畅销的秘密人只会买自己需要的东西吗?好东西自然不愁卖吗?只要能满足生猪生长需要的饲料就一定畅销吗?本来这些问题是不需要加问号的,也是应当肯定的,但是因为购买行为里掺杂了人的心     

鸡败血支原体病的诊治

鸡败血支原体病又称为鸡慢性呼吸道病，因该病发展缓慢，病程较长，死亡率不高，而常被养鸡户忽视，但其长期存在和蔓延，造成的幼鸡生长不良，成年鸡产蛋减少，经济损失极大。下面对该病的诊治作以概述。     

Hypocalcemia in a dog

A case of hypocalcemia was presented with a concurrent hyperphosphatemia. Normal renal function tests excluded primary renal insufficiency. The diet was thought to contain a normal ratio of calcium and phosphorus and, therefore, nutritional secondary hyperparathyroidism was not considered. The radiographs showed normal bone density and the dog was not lame. Concentrations of immunoreactive parathyroid hormone were measured in an attempt to classify the etiology. The dog was successfully managed with calcium supplementation and vitamin D(3) or oral calcium alone.     

Phycomycosis in a dog

SUMMARY A case of phycomycosis, with skin lesions, in a dog is reported. Hyphomyces destruens (Pythium gracile) was identified from aspirate collected from a regional lymph node, and characteristic hyphae were seen in stained sections of a biopsy specimen of affected skin. Incidence, pathogenesis and therapy are discussed.     

Protothecosis in a dog

A case of a disseminated algal infection is reported in a young rough-coated collie dog with progressive neurologic deficits, blindness, and hemorrhagic diarrhea. Prototheca zopfii organisms were cultured from feces, urine, and blood. At necropsy, granulomas containing typical organisms were identified within the proximal colon, heart, kidneys, and eyes.     

Oligodendroglioma in a dog

Oligodendroglioma of the left thalamic region of the brain of a dog is described. Over a period of approximately 6 months the tumour caused progressive posterior ataxia, listlessness, tilting of the head and circling to the right, nystagmus, blindness of the right eye and atrophy of the temporal muscle. The histological features on which the diagnosis was based were the presence of characteristically-shaped basophilic neoplastic cells with a clear space or ‘halo’ around them, scanty cytoplasm, small, stubby processes seen in silver-stained sections, and vascular proliferation. Résumé. On décrit un oligodendrogliǒme dans la partie gauche du thalamus du cerveau d'un chien. Après une période d'environ six mois, la tumeur avail causé une ataxie postérieure progressive, de l'apathie, un penchement de la těte avec oscillation à droite, un nystagme, une cécité de l'oeil droit et une atrophie du muscle temporal. Les particularités histologiques sur lesquelles on s'est fondé pour le diagnostic comprenaient la présence de cellules néoplastes basophiles d'une forme caractéristique, entourées d'un cercle clair ou ‘halo’, un cytoplasme insuffisant, des fromations petites et trapues observées dans les sections teintées d'argent et une proligération vasculaire. Zusammenfassung. Ein Fall von Oligodendrogliom der linken Thalamusregion des Gehirns eines Hundes wird beschrieben. Über eine Periode von annähernd 6 Monaten verursachte der Tumor progressive posteriore Ataxie, Teilnahmslosigkeit, Schiefhaltung des Kopfes und Kreisbewegung nach rechts, Nystagmus, Blindheit des rechten Auges und Atrophie des Musculus temporalis. Die histologischen Merkmale, auf denen die Diagnose beruhte, waren die Anwesenheit charakteristisch geformter basophiler neoplastischer Zellen, die von einem freien Raum oder “Lichthof” umgeben waren, spärliche Cytoplasmen, kleine, knollige Wucherungen, die in silbergefärbten Schnitten beobachtet wurden, und vasculäre Proliferation.
