我国即将加入WTO ,这对我国畜牧业而言无疑是一大机遇 ,但同时也是一大挑战。许多国家对动物产品的要求 ,不仅要有满意的质量和合理的价格 ,还要求在饲养、运输和屠宰过程中给动物以一定的“福利”。事实上 ,动物福利与动物的生产性能也有多方面的联系。“动物福利”即“动物善待” ,我国许多畜牧兽医工作者对这方面还缺乏了解。为此 ,我们刊登上海市畜牧兽医站王永康推广研究员翻译的这篇文章以供读者参考。  相似文献   

Nutrient intake of horses in Thoroughbred and Standardbred stables     

LL SOUTHWOOD  DL EVANS†  WL BRYDEN‡  RJ ROSE 《Australian veterinary journal》1993,70(5):164-168

SUMMARY Twenty-five Thoroughbred (TB) and 25 Standardbred (SB) stables were visited to determine their feeding practices. The ingredients of the main feed of the day for a mature gelding of average size in full training were weighed at each stable. Nutrient content of diets was calculated using published data for the individual ingredients. Results are expressed as mean±sd. The estimated body weight of TB horses was 493±34 kg and 437±32 kg for SB horses. There was considerable variation in diet composition and nutrient intake between stables. The TB trainers fed 11.0±2.4 kg and SB trainers 11.8±2.5 kg per day. The concentrate component of the diet weighed 7.8±1.6 and 7.7±2.3 kg for TB and SB stables, respectively, and the roughage component for TB horses 3.3±1.4 and SB horses 4.1±1.4 kg per day. The digestible energy intake of horses at TB stables was 129±29 MJ per day and at SB stables 132±31 MJ per day. Crude protein intake of TB horses was 1452±363 g and SB horses 1442±338 g per day. There were differences in some feeding practices at TB and SB stables. Standardbred trainers fed more roughage than TB trainers. Standardbred trainers fed chaffed lucerne (alfalfa) and cereal hays as the major roughage, whereas TB trainers fed more hay. The major hay type fed by TB trainers was lucerne, whereas many SB trainers preferred clover hay. Both trainers fed oats as the major grain, but TB trainers fed slightly more maize (corn) than SB trainers. The SB trainers fed barley as part of the concentrate component of the diet, whereas TB trainers usually fed boiled barley and linseed oil in winter only. Although many trainers used vitamin and mineral supplements, this appeared unnecessary in many Instances, especially with respect to Iron. Calcium and NaCI supplementation was necessary for some diets. We concluded that while there was a wide range in feed intake and diet composition for both TB and SB horses, average nutrient intakes were similar to National Research Council (1989) recommendations for horses performing intense work.  相似文献

Detection and genetic diversity of porcine rotavirus A,B and C in eastern Australian piggeries

Rotaviruses (RV) have a high prevalence in piggeries worldwide and are one of the major pathogens causing severe diarrhoea in young pigs. RV species A, B, and C have been linked to piglet diarrhoea in Australian pig herds, but their genetic diversity has not been studied in detail. Based on sequencing of the structural viral protein 7 (VP7) RVA G genotypes G3, G4 and G5, and RVC types G1, G3, G5, and G6 have been identified in Australian piggeries in previous studies. Although occurrence of RVB was reported in Australia in 1988, no further genetic analysis has been conducted. To improve health management decisions in Australian pig herds, more information on RV prevalence and genetic diversity is needed. Here, 243 enteric samples collected from 20 pig farms within Eastern Australia were analysed for the presence of RV in different age groups using a novel PCR-based multiplex assay (Pork MultiPath™ enteric panel). RVA, RVB, and RVC were detected in 10, 14, and 14 farms, respectively. Further sequencing of VP7 in selected RV-positive samples revealed G genotypes G2, G5, G9 (RVA), G6, G8, G14, G16, G20 (RVB), and G1, G3, G5, G6 (RVC) present. RVA was only detected in young (<10 weeks old) pigs whereas RVB and RVC were also detected in older animals (>11 weeks old). Interestingly, RVB and RVC G-type occurrence differed between age groups. In conclusion, this study provides new insights on the prevalence and diversity of different RV species in pig herds of Eastern Australia whilst demonstrating the ability of the Pork MultiPath™ technology to accurately differentiate between these RV species.  相似文献

Detection of Ureaplasma diversum in the upper airways of Australian feedlot cattle     

RJ Barnewall  IB Marsh  PMV Cusack  F Galea  N Sales  JC Quinn 《Australian veterinary journal》2023,101(6):254-257

Bovine respiratory disease (BRD) exerts a major impact on the beef cattle industry nationally and worldwide, with a range of aetiological factors impacting its pathogenesis. Previous research has focussed on an increasing number of bacteria and viruses that have been shown to play a role in eliciting disease. Recently, additional agents have been emerging as potential contributors to BRD, including the opportunistic pathogen Ureaplasma diversum. To determine if U. diversum was present in Australian feedlot cattle and if that presence was linked to BRD, nasal swabs were collected from a cohort of 34 hospital pen animals and compared to 216 apparently healthy animals sampled contemporaneously at feedlot induction and again after 14 days on feed at an Australian feedlot. All samples were subjected to a de novo polymerase chain reaction (PCR) assay targeting U. diversum in combination with other BRD agents. U. diversum was detected at a low prevalence in cattle at induction (Day 0: 6.9%, Day 14: 9.7%), but in a significantly greater proportion of cattle sampled from the hospital pen (58.8%). When considering the presence of other BRD-associated agents, co-detection of U. diversum and Mycoplasma bovis was most common in hospital pen animals receiving treatment for BRD. These findings suggest that U. diversum may be an opportunistic pathogen involved in the aetiology of BRD in Australian feedlot cattle, in combination with other agents, with further studies are warranted to identify if a causal relationship exists.  相似文献

Distribution of immune cells in the female reproductive tract in uninfected and FIV infected cats     

Butterworth JL  English RV  Jordan HL  Tompkins MB 《Veterinary immunology and immunopathology》2001,83(1-2):37-51

Cell-free and cell-associated FIV effectively cross the mucosa of the feline female reproductive tract. To identify possible cellular targets of FIV and to characterize changes in mucosal immunity after infection, we examined the types and numbers of immune cells residing in the reproductive tracts of control and intravaginally FIV-infected cats. Sections of the vestibule, vagina, cervix, uterus, and ovaries, were examined by immunohistochemistry for CD4+ and CD8+ T lymphocytes, CD22+ B lymphocytes, CD1a+ dendritic cells, and CD14+ macrophages. The reproductive tract of uninfected cats contained substantial numbers of CD8+ T lymphocytes, CD4+ T lymphocytes and macrophages, as well as moderate numbers of CD1a+ dendritic cells, and few B lymphocytes. The most prominent change between FIV- and FIV+ cats was a marked decrease in the concentration of CD4+ T lymphocytes resulting in inverted CD4+:CD8+ ratios throughout the reproductive tract of infected cats. There was also a trend towards increasing numbers of CD1a+ dendritic cells in the intravaginally-infected FIV+ cats, and decreasing numbers of macrophages and CD22+ B lymphocytes. This study indicates that similar to the peripheral immune system, FIV infection is associated with CD4+ cell loss and reduced CD4+:CD8+ ratios in the female reproductive mucosal tissue.  相似文献   

Zollinger-Ellison syndrome and myelofibrosis in a dog   总被引：1，自引：0，他引：1

Zollinger-Ellison syndrome and myelofibrosis were diagnosed concurrently in a 10-year-old neutered female Brittany Spaniel. Documentation of gastric ulceration, hypergastrinemia, and gastrin-secreting islet cell tumor with splenic metastases facilitated the diagnosis of Zollinger-Ellison syndrome. Patchy long-bone medullary sclerosis, nonregenerative anemia and thrombocytopenia, multiple acellular bone marrow aspirates, marked splenic extramedullary hematopoiesis, and acellular core bone marrow biopsy with areas of necrosis and fibrosis supported the diagnosis of myelofibrosis. Despite the medical and surgical management attempted, the dog was euthanatized because of signs of severe intractable bone pain. Myelofibrosis has been documented in association with canine and human neoplastic disease. A direct causal relationship between gastrinoma and myelofibrosis was not clearly established in this instance.  相似文献
