皇竹草的栽培与利用 总被引：2，自引：0，他引：2
皇竹草是一种多年生禾草类植物,是由象草和非洲狼尾草杂交育成。学名为Ponnisetum hydridum,英文名为Hybrid Giant Napier,原产于哥伦比亚,因其叶长,茎似斑竹,又称竹草、甘蔗草、巨象草等。皇竹草最早是为改善生态环境从哥伦比亚引入我国海南省的。近几年的研究发现它具有很好的应用前景,可以作为一种营养价值较好的食用蛋白质新资源。皇竹草作为良好的动物饲料,近些年来已被我国海南、四川、湖南、江苏、广东、广西、江西等省份引种并应用。1皇竹草的饲用价值1.1优良生物特性皇竹草生长期短,产量极高,分蘖多,再生能力强。当年栽培的皇竹… 相似文献

试验旨在探究基肥法、追肥法，老篼繁殖、茎芽分蘖繁殖对皇竹草生长性能的影响。试验在相同茎芽分蘖繁殖方法下，探究基肥法、追肥法对皇竹草地径、株高、分蘖数及单株生物量的影响；在相同追肥法下，探究老篼繁殖、茎芽分蘖繁殖组对皇竹草地径、株高、分蘖数及单株生物量的影响。结果显示，8月下旬基肥法皇竹草株高、分蘖数均极显著高于追肥法（P<0.01），单株生物量极显著低于追肥法（P<0.01）；老篼繁殖皇竹草株高、分蘖数和单株生物量均极显著高于茎芽分蘖繁殖（P<0.01）。9月下旬基肥法皇竹草单株生物量极显著低于追肥法（P<0.01）；老篼繁殖皇竹草单株生物量极显著低于茎芽分蘖繁殖（P<0.01）。研究表明，在基肥下，皇竹草分蘖强度大、分蘖数多；当追肥后，皇竹草生长迅速、单株生物量增多。在老篼繁殖、茎芽分蘖繁殖方法下，当皇竹草密度不大时，皇竹草单株生物量与分蘖数呈正相关；密度过大时，皇竹草单株生物量与分蘖数呈负相关。 相似文献

The anabolic steroid and antimicrobial growth promoters may be regarded as the first generation of animal growth promoters or performance enhancers. There is major investment in the development of new techniques to improve the efficiency of farm animal production. These techniques are reviewed under the headings of growth hormone (somatotrophin) and related techniques, immunological techniques, the beta-adrenergic agonists and the direct genetic manipulation of farm animals. 相似文献

Perineural nerve blocks are often used in equine practice, especially since the use of diagnostic and surgical procedures in the standing sedated horse have expanded over recent decades. The purpose of this review is to discuss the different perineural nerve blocks for the equine head. The review starts with the currently most used blind approaches as described in textbooks and scientific studies. In human medicine, the role of guided techniques, such as ultrasound guidance, advanced imaging guidance and nerve stimulator guided techniques, is very extensively described. These techniques are promising to use in equine medicine as well. The first studies that describe these techniques in equine cases are also discussed in this review, as well as the possibilities for neuromodulation in equine pain syndromes like equine trigeminus-mediated headshaking and the role of perineural nerve blocks in diagnosing this syndrome. 相似文献

Virus isolation, immunofluorescent staining and DNA probe hybridization, three techniques for the detection of pseudorabies virus (PRV) have been compared in pigs experimentally infected with the Thailand CB-1 strain PRV. The virus isolation and DNA hybridization detection demonstrated a good correlation in detecting infection in live animals by nasal swabbing. In white blood cells an earlier detection was seen with the DNA-hybridization techniques. Consistent results with all the three techniques tested were found in organ materials as nasal mucosa and tonsils as well as in the olfactory bulb. 相似文献

Objectives – To introduce the basic equipment necessary to perform interventional radiology (IR) techniques in the veterinary setting, particularly those procedures of interest to the criticalist. Data Sources – Veterinary and human literature as well as author's experience. Human Data Synthesis – Since the 1950s, diagnostic angiography has played an important role in human medicine. However, over the last 2–3 decades, this once purely diagnostic modality has become a subspecialty in human medicine with vast applications throughout the body. These techniques have replaced more invasive surgeries as the standard‐of‐care in many circumstances. Veterinary Data Synthesis – Although comparable data are not available in the veterinary literature, many IR and interventional endoscopy techniques are poised to replace more invasive procedures in veterinary medicine. In addition, these techniques have already been shown to offer treatment options for patients in whom more traditional therapies have failed, have been declined, or are not indicated due to comorbidities or substantial risk to patient health. Conclusions – Like our human medical counterparts, the use of IR techniques will likely play and increasingly important role in the care of veterinary patients. With this in mind, it is important to become familiar with both the equipment used in these techniques as well as their applications both currently in clinical cases and in the near future. 相似文献

Transgenesis offers new possibilities to rapidly modify the genome of living organisms. The application of transgenesis to farm animals faces many problems, more than those observed in the transgenesis of laboratory animals, as there are currently many different techniques available to obtain transgenic animals, which all have problems regarding low efficiency and high costs. When these techniques are applied to farm animals the problems concerning transgenesis are multiplied. Two main techniques, male pronuclear microinjection and sperm mediated gene transfer, utilised in farm animal transgenesis, are briefly presented. The improvement of these techniques and the employment of other biotechnologies such as cloning, could expand the uses of transgenic farm animals for human health. 相似文献

Ultrasonography is the imaging technology of choice for the evaluation of the reproduction system and of pregnancy in both humans and animals. Over the past 10 years, there have been significant technological improvements of the equipment, while new technologies have been developed. Doppler, contrast-enhanced ultrasonography, elastography, and 3D/4D ultrasonography are advanced ultrasound techniques that have been designed as methods to increase the diagnostic sensitivity of two-dimensional (b-mode) ultrasound, and not as stand-alone tests. The basic physics as well as the advantages and limitations of these advanced ultrasound methods are briefly described. In the reproductive diagnostics of small animals, these techniques have gained an increased popularity as proved by the increased publication of several reports that are also briefly summarized in this review. Clinical applicability is to date limited because of a lack of research on the diagnostic value in concrete situations. Future research projects should focus also on standardization of the used techniques, on determination of thresholds to discriminate between healthy or diseases or fertile versus infertile and on the predictive value of advanced ultrasound findings. Continuing development and optimization of different ultrasound techniques as well as the increase of related scientific interest and worldwide research promises that the clinical interest on the use of advanced ultrasound techniques will increase in future. 相似文献
