牛磺酸的生产及其在畜禽养殖中的应用 总被引：1，自引：0，他引：1
牛磺酸是动物体内一种半必需、游离氨基酸;它具有广泛的生物学功能,可调节神经传导,维持视网膜、内分泌、肝脏、心脏功能,促进脑的发育,抗氧化等。因其具有独特的生理及药理功能,已广泛应用于医药和食品行业。作者侧重介绍了牛磺酸在动物机体中的代谢情况及牛磺酸的生产,概述了牛磺酸对畜禽生长性能、繁殖能力、免疫力、采食等方面的作用,展望了牛磺酸在畜禽养殖业的应用前景。 相似文献

牛磺酸的研发现状 总被引：7，自引：0，他引：7
牛磺酸〔2-氨基乙磺酸(H2N-CH2-CH2-SO3H)Taurine〕又名牛黄酸、牛胆酸、牛胆碱、牛胆素,因182年首次从牛胆之中分离出来而得名[1]。过去被认为是机体内含硫氨基酸无功能的终末代谢产物,但近年来研究证明牛磺酸具有广泛的生物学功能[2]。牛磺酸不仅参与维持机体内环境稳态,而且在中枢、消化、生殖心血管、免疫和内分泌等系统生理功能正常发挥具有重要的调节作用,机体内几乎所有正常生理功能的维持和调节都需要牛磺酸的参与,其作用可与水分子的作用相提并论[3]。牛磺酸的生物学作用是近十几年来国际学术界的研究热点之一,国际组织自1990… 相似文献

新型添加剂牛磺酸在养殖业上的应用研究 总被引：1，自引：0，他引：1
孙艳侠 《养殖与饲料．饲料世界》2006,(11):35-36
牛磺酸（Taurin）也称牛黄酸、牛胆酸、牛胆碱、牛胆素，它是人、猴、猿、家畜、家禽等的条件性必需氨基酸，自身只能合成其生理需要的30％～40％，也就是说自身合成牛磺酸的数量有限，不能满足机体需要，它们所需的牛磺酸主要从食物中获得。牛磺酸参与维持机体内环境稳态调节，对神经、消化、生殖、心血管、免疫和内分泌等生理功能的正常发挥具有重要的调节作用。其作用可与水分子的作用相提并论，被广泛作为保健食品、医药和饲料添加剂，在动物营养中具有十分重要的作用。本文对牛磺酸在养殖业中的应用及其发展前景作一阐述，以促进它作为新型添加剂在养殖业中的推广和应用。 相似文献

Oxidative stress is ubiquitous in livestock and poultry production.When the body is in the situation of harmful stimulation in vitro or in vivo,the oxidation system and antioxidant system are in a state of imbalance,leading to metabolic disorders,which depresses the growth and development of animals,decreases disease resistance and quality of livestock products seriously,and has a negative impact on the production and health of livestock and poultry.So it is important to find an effective measure to alleviate the health of livestock and poultry.Lipoic acid,tea polyphenol,VE and other antioxidants play significant roles in reducing oxidative stress.In this paper,the effects of oxidative stress on broiler and mitigation technology research were outlined. 相似文献

Board-invited review: intrauterine growth retardation: implications for the animal sciences 总被引：1，自引：0，他引：1
Intrauterine growth retardation (IUGR), defined as impaired growth and development of the mammalian embryo/fetus or its organs during pregnancy, is a major concern in domestic animal production. Fetal growth restriction reduces neonatal survival, has a permanent stunting effect on postnatal growth and the efficiency of feed/forage utilization in offspring, negatively affects whole body composition and meat quality, and impairs long-term health and athletic performance. Knowledge of the underlying mechanisms has important implications for the prevention of IUGR and is crucial for enhancing the efficiency of livestock production and animal health. Fetal growth within the uterus is a complex biological event influenced by genetic, epigenetic, and environmental factors, as well as maternal maturity. These factors impact on the size and functional capacity of the placenta, uteroplacental blood flows, transfer of nutrients and oxygen from mother to fetus, conceptus nutrient availability, the endocrine milieu, and metabolic pathways. Alterations in fetal nutrition and endocrine status may result in developmental adaptations that permanently change the structure, physiology, metabolism, and postnatal growth of the offspring. Impaired placental syntheses of nitric oxide (a major vasodilator and angiogenic factor) and polyamines (key regulators of DNA and protein synthesis) may provide a unified explanation for the etiology of IUGR in response to maternal undernutrition and overnutrition. There is growing evidence that maternal nutritional status can alter the epigenetic state (stable alterations of gene expression through DNA methylation and histone modifications) of the fetal genome. This may provide a molecular mechanism for the role of maternal nutrition on fetal programming and genomic imprinting. Innovative interdisciplinary research in the areas of nutrition, reproductive physiology, and vascular biology will play an important role in designing the next generation of nutrient-balanced gestation diets and developing new tools for livestock management that will enhance the efficiency of animal production and improve animal well being. 相似文献

Copper is one of the essential trace elements, which plays an important part in growth and development of animals. To solve the shortcomings of high inorganic copper doses in practical production,development and effective utilization of new organic copper source has become the focus of the current industry. The author introduced the nutrition function, distribution, absorption, transshipment and excretion of copper in the body,summarized the research situation and application prospects of different copper sources in livestock production, hoping to provide the reference for popularization and application of organic copper in actual production. 相似文献
