犬细小病毒病是由细小病毒引起的一种急性传染病，该病无明显的季节性，但寒冷季节多发。该病潜伏期为7～14天，感染率可达90％。幼犬易感，常表现为急性心肌炎，死亡率可达60％-70％，中青年犬感染时，常表现出血性肠炎，死亡率可达20％左右。因此，该病的早期诊断与治疗非常重要。笔者现以许昌东郊一养犬场为例将该病的治疗措施介绍如下。 相似文献

猪水肿病又名大肠杆菌毒血症，俗称小猪摇摆症．是断乳仔猪（断乳后1～2周）常见多发病，呈地方性流行，病死率高（约90％）。本病无明显的季节性，但以春季的4—5月和秋季的9～10月发病较多．特别是在气候骤变和阴雨季节更易发病。近几个月来，山东省淄川区一些养猪场相继发生仔猪水肿病，由于该病发病突然，且致死率很高，易给养猪业造成较大的损失。笔者在临床的早期治疗中采用中西医结合疗法，取得了较好的疗效．现将治疗方法总结如下. 相似文献

我国自1979年首次发现传染性法氏囊病(IBD)以来，IBD已成为严重威胁我国养鸡业的重要疫病之一。IBD病毒(IBDV)在上世纪70年代后期到80年代表现为强毒型，自90年代初开始出现超强毒型IBDV。目前该病在流行过程中，病原的毒力发生了变化，加上鸡群中免疫水平不一致，导致该病临床症状和病理变化等方面出现非典型化趋势，给诊断和防制带来了许多麻烦。 相似文献

Abomasal ulceration occurs commonly in suckling calves, and the cause for the high prevalence of abomasal ulceration is unknown. We hypothesized that diet may play a role in the etiopathogenesis of abomasal ulceration. Six male dairy calves with an abomasal body cannula suckled fresh Holstein cow's milk, all milk-protein milk replacer, or combined milk- and soy-protein milk replacer twice daily at 12% of body weight/d. Abomasal luminal pH was measured every second for 24 hours by using a miniature glass pH electrode. Mean 24-hour abomasal luminal pH for all milk-protein milk replacer (3.22) and combined milk- and soy-protein milk replacer (3.27) were similar but significantly (P < .05) higher than that for cow's milk (2.77; standard error = 0.08). Both milk-replacer formulations failed to clot after the addition of chymosin, whereas cow's milk clotted within 2 minutes. The in vitro titration curve of cow's milk and all milk-protein milk replacer were similar, but different to that of combined milk- and soy-protein milk replacer. The osmolalities of all milk-protein milk replacer (375 mOsm/kg) and combined milk- and soy-protein milk replacer (410 mOsm/kg) were greater than that of cow's milk (278 mOsm/kg). The slightly lower mean abomasal luminal pH in calves suckling cow's milk, compared to milk replacer, was probably due to clotting of cow's milk, with extrusion of low pH whey, and a slower rate of abomasal emptying caused by the hyperosmolality of milk replacer. Examination of our results suggests that suckling cow's milk may increase the prevalence of abomasal ulceration by decreasing mean luminal pH, although this remains to be determined. 相似文献

Lamb, beef and cow's milk are common causes of cutaneous adverse food reactions in dogs. The aim of this study was to identify the proteins responsible for cutaneous adverse reactions to these foods. Ten dogs with allergen-specific serum immunoglobulin (Ig)E to lamb, beef and cow's milk were included in the study. These dogs had been diagnosed with cutaneous adverse food reactions by convincing clinical history and food-elimination diet trials followed by challenge exposure. Sera were analysed by enzyme-linked immunosorbent assay with bovine proteins and SDS-PAGE immunoblots with lamb, beef and cow's milk extracts. All the dogs had specific IgE against bovine IgG, and it was the only protein in the cow's milk extract that bound IgE from the sera studied. In the lamb and beef extracts, the major allergens recognized by the specific IgE of most sera had molecular masses between 51 and 58 kDa, which were identified as phosphoglucomutase and the IgG heavy chain. Other IgE-binding proteins with molecular masses of 27, 31, 33, 37 and 42 kDa were also detected with some sera. Our results indicate that bovine IgG is a major allergen in cow's milk and hence it appears to be a source of cross-reactivity with beef and probably with lamb because of the high homology with ovine immunoglobulins. These results are similar to those found for meat allergy in humans. However, this is the first time that phosphoglucomutase has been identified as an important allergen involved in allergic reactions to lamb and beef. 相似文献

In the past, it has been reported that neonatal diets made from unheated cow's milk were superior to those made from heated cow's milk. It was observed that piglets were equally protected from rotaviral diarrhea when they were fed diets made from either unheated milk that came from a cow immunized against porcine rotavirus or from a cow that was not immunized. Because of this observation, we examined four pools of "normal" cows' colostrum and 58 samples of "normal" cow's milk for the presence of antibody to rotavirus. All pools of colostrum, collected in four different years, had immunofluorescent antibody titers of 1:100 to rotavirus. Seventy-two percent of the samples of milk were also positive--titer no higher than 1:10. Antibodies to rotavirus were found in cow's milk at a creamery prior to but not after pasteurization. Rotaviral antibodies were detected in one out of eight brands of milk bought at the market--perhaps indicating inadequate pasteurization for this brand. These results support the proposition that, at least in part, unheated milk is superior to heated milk because unheated milk contains antibody to an ubiquitous enteropathogen like rotavirus. 相似文献

Ten calves which had contracted acute diarrhoea caused by rotavirus, coronavirus and Cryptosporidium were used to test the hypothesis that feeding lactose-hydrolysed cow's milk instead of unprocessed cow's milk improves sugar absorption in diarrhoeic calves. The animals were rehydrated with an orally administered solution containing electrolytes and glucose. Thereafter the calves received one test meal of whole fresh cow's milk whose lactose had been hydrolysed by added lactase and one test meal of unprocessed cow's milk at an interval of 24 h in a cross-over design trial. In comparison with unprocessed milk, the intake of milk containing hydrolysed lactose resulted in a slight decrease of mean breath hydrogen concentration (P = 0.18), but also a slight decrease of mean blood galactose concentration (P = 0.14). There was no treatment effect on mean plasma glucose concentration. Peak plasma glucose and blood galactose concentration tended to be delayed after the intake of lactose-hydrolysed milk, which implies that gastric emptying was probably delayed. The results show that feeding milk which contains hydrolysed lactose does not significantly improve lactose utilization in calves that are suffering from benign infectious diarrhoea. 相似文献

Milk and blood serum from clinically mastitis infected, subclinically mastitis infected and healthy Friesian cows (15 samples from each of 3 groups) were evaluated for macrominerals (sodium, potassium, calcium, magnesium and phosphorus). The milk from cows infected with subclinical mastitis revealed a significant decrease in potassium (P < 0.001) and a significant increase in sodium and phosphorus content (P < 0.01). Similarly, the milk from cows with the clinical form of the disease showed a significant increase in sodium (P < 0.001) and a significant decrease in potassium, magnesium (P < 0.001) and calcium (P < 0.01). Comparison of healthy cow's milk with that from cows with subclinical mastitis revealed a highly significant increase in sodium (P < 0.001). Comparison of healthy cow's milk with that of clinically mastitic milk showed a highly significant decrease in levels of calcium, magnesium (P < 0.001) and potassium (P < 0.01). However, sodium increased highly significantly (P < 0.001). Comparison of macro-minerals in milk from cows with subclinical and clinical mastitis revealed a significant decrease in potassium contents (P < 0.05) compared with that of healthy cows. Potassium levels were found to decrease significantly (P < 0.05) in subclinically infected cow's blood serum. However, calcium and phosphorus showed a significant decrease (P < 0.01) in blood serum samples from the clinically infected cows. 相似文献
