初生仔猪免疫力差,消化器官未发育完全,加之环境与代谢方式的转变,造成仔猪易被病原微生物感染。随着集约化程度提高及全封闭饲养模式的采用,仔猪病毒性腹泻成为了常发病,对此需分析病因,并制订相应的管理和预防措施,以减少发病。新生仔猪病毒性腹泻主要与免疫及饲养管理因素等有关,同时也与母猪的饲养管理情况、生物安全措施,舍内温度,猪的营养水平有密切关系。  相似文献

正在猪养殖业中,许多陈旧的猪养殖方式,由于缺乏科学合理性,经常引发大量仔猪患病以及死亡的情况,给饲养者带来了巨大的损失。而随着养殖业的不断发展,出现了更多新型的养殖技术,由于当前仔猪饲养技术还不成熟,不能按照猪生理特点给出详细的养殖管理技术方案,因此如何更合理的完善猪饲养管理技术仍然是当前猪养殖业的重要课题。1哺乳仔猪的生理特点1.1发育快代谢旺盛乳猪刚出生时,体积小体重轻,但是生长发育极为迅速,  相似文献

一般将28日龄以内还未断奶的猪称为哺乳仔猪.哺乳仔猪具有新陈代谢旺盛、消化和免疫系统发育不健全、体温调节能力差等生理特点.对哺乳仔猪加强饲养管理,不仅可以提高其成活率、增加其断奶重,而且有利于保育猪和育肥猪的生长发育,进而对养殖场的经济效益产生影响.现主要通过阐述哺乳仔猪的生理特点和饲养管理中的关键技术点,为广大养殖户...  相似文献

在仔猪饲养当中,断奶仔猪的饲养十分关键,断奶是仔猪出生之后所面临的重要应激性事件,仔猪在断奶之后一般需要依赖固体饲料生存,但是其自身的消化功能还没有完全发育,所以很容易出现营养应激情况.此外,仔猪在断奶期内受到环境影响与心理影响等,生长发育也会出现变化,如果断奶仔猪无法得到较好的饲养管理,甚至会出现僵猪情况,这样会给养殖人员带来极为严重的经济损失,对于仔猪饲养的推广也极为不利.笔者将在本文当中针对断奶仔猪的饲养管理进行相关分析,现根据具体情况作如下分析.  相似文献

影响仔猪胃肠道发育的因素   总被引:1,自引:0,他引:1  
仔猪胃肠发育的情况直接影响了营养物质的消化、吸收及利用,及时找到影响其发育的因素对仔猪的营养管理是非常有意义的。目前发现的诸多因素中,生长因子及营养物质对其发育起到促进作用,而抗营养因子往往对其发育不利。本文从生长因子、营养物质到抗营养因子角度出发,分析了它们对仔猪肠道发育影响,为今后合理配制仔猪饲养阶段的日粮提供依据。  相似文献

动物胃肠道被视为抵御外界病原体的一道重要屏障,胃肠道健康与动物机体健康密不可分。动物胃肠道中栖息着大量多样性的微生物种群,微生物之间的相互作用复杂且多样,微生物的功能和种类组成影响着胃肠道的稳态平衡。微生物群通过定植在胃肠道黏膜,在黏膜免疫系统发育中起着至关重要的作用,同时也对胃肠道健康与功能起着重要作用。调控胃肠道健康的方式有很多种,目前主要通过添加益生元、益生素等非营养物质和营养调控剂来调控胃肠道功能和维护胃肠道健康。但相较于其他营养调控剂来说,免疫球蛋白调控胃肠道的研究报道较少,属于新的免疫调控技术,其具有特异专一性、易生产且成本低、效果显著等优点。免疫调节是一种高效且相对安全的调节方式。作者介绍了4种免疫球蛋白(IgG、IgA、IgY、纳米抗体)的主要理化性质,总结了现阶段免疫球蛋白对胃肠道功能调节的进展及展望,从而为应用免疫球蛋白调控动物胃肠道健康和促进营养代谢提供指导。  相似文献

The value of proper diet in the management of the gastrointestinal patient has been demonstrated. As experience and knowledge increase, diets will become more refined to address specific diet-related abnormalities. There is an increasing awareness in veterinary medicine, and justifiably so, of the benefit of nutritional support, administered enterally or parenterally. Aggressive, early, and adequate nutritional support may be the most important factor responsible for a successful response to other aspects of therapy and recovery, and has to represent an improvement in veterinary medicine.  相似文献

Dietary protein, carbohydrates, fats and fibre have marked influences on gastrointestinal tract function and dysfunction. This article reviews the nutritional management of common gastrointestinal disorders in companion animals and introduces some of the current areas of research including probiotics, prebiotics, protein-hydrolysate diets, immunonutrition and dietary fibre.

Nutritional management of oesophageal disease revolves around varying the consistency of the diet and feeding the animal from an elevated container. Provision of bowel rest remains the mainstay of the management of acute gastroenteritis but food-based oral rehydration solutions are a useful adjunct. The recommended diet for chronic small bowel diarrhoea is a highly digestible, hypoallergenic, gluten-free, low-lactose and low-fat diet with modest amounts of fermentable fibre. The use of probiotics in the management of diarrhoea in companion animals has not yet been shown to be beneficial. It is likely that prebiotics will prove more effective than probiotics in the prevention of enteropathogenic infections.

Approximately 50% of cats in New Zealand that suffer from chronic idiopathic vomiting or diarrhoea will respond to a novel-protein-elimination diet and approximately 30% meet the diagnostic criteria for food sensitivity. Growing evidence supports the use of protein-hydrolysate diets in the management of inflammatory bowel disease and further advances in immunonutrition are expected. The dietary management of colitis should include a hypoallergenic diet with a fermentable fibre source.

Manipulation of the diet provides clinicians a powerful therapeutic strategy to be used alone or concurrently with drug therapy in the management of gastrointestinal disorders.  相似文献

The gastrointestinal tract of neonatal calves is relatively mature but still requires morphological and functional changes. The intake of colostrum with its nutrient and non-nutrient components exerts marked effects on gastrointestinal development and function. Colostrum intake provides immunoprotection (passive immunity by immunoglobulins) and is essential for survival of neonates of most species. Furthermore, there are important transient as well as long-lasting systemic effects on the nutritional status, on metabolism, and on various endocrine systems due to intake of nutrient and non-nutrient colostral components that contribute to survival in the stressful postnatal period. Colostrum is much more than just a supplier of immunoglobulins.  相似文献

Abnormalities affecting the pancreas or small intestine can result in malabsorption and diarrhoea by interfering with either the degradative or absorptive phases in the handling of one or more nutrients. Diet may be involved in the pathogenesis of certain disorders and can also influence the nature and severity of the clinical manifestations of gastrointestinal disease. Exocrine pancreatic insufficiency can have serious nutritional consequences as the pancreas plays a crucial role in the degradation of the main dietary constituents. Whereas gastrointestinal peptidases help compensate for pancreatic protease deficiencies, malabsorption of carbohydrate and fat occurs and can result in osmotic and secretory diarrhoea, respectively. Small intestinal disease can result in malabsorption by interference with either the number or functioning of individual enterocytes. Diarrhoea may be due to stimulated secretion and diminished absorption of fluid and electrolytes, and also to the osmotic effects of small molecules, particularly carbohydrates, that remain in the lumen. Specific therapy depends on the disease. Dietary management is also important, for example with a restricted fat diet containing highly digestible carbohydrate and a high quality protein source. Where a specific dietary sensitivity is suspected, such as gluten-enteropathy, a hypoallergenic diet may prove particularly valuable.  相似文献

为研究四君子汤对脾虚大鼠胃肠运动和胃肠激素含量影响,用营养性半固体糊灌胃法测定大鼠胃排空率和肠推进率,采集胃窦基础电位信号,ELISA法测定胃肠组织中CCK、MTL蛋白水平。结果显示,与对照组比,脾虚组胃排空率下降,肠推进率上升,胃电振幅和频率均降低;胃窦内CCK明显升高(P0.05),十二指肠和空肠内CCK显著降低(P0.05);MTL在脾虚大鼠消化道内呈整体降低趋势,仅在空肠内极显著降低(P0.01)。与脾虚组比,治疗组胃排空率升高,肠推进率下降,胃电振幅和频率均回升;胃窦内CCK明显降低(P0.05),十二指肠和空肠内CCK显著升高(P0.05);消化道内MTL含量整体回升。由此可见,四君子汤可以平衡紊乱的胃肌电活动,调节脾虚大鼠的胃肠运动,调节消化道内局部CCK和MTL含量。  相似文献
