Topic:Biotechnology
Biotechnology in horses encompasses the application of biological techniques and tools to enhance equine health, performance, and reproduction. This field includes genetic engineering, cloning, and the development of vaccines and therapeutics tailored to equine physiology. Techniques such as gene editing and stem cell therapy are explored for their potential to address genetic disorders, improve tissue regeneration, and enhance disease resistance in horses. Additionally, advancements in reproductive biotechnology, such as artificial insemination and embryo transfer, contribute to genetic diversity and breeding efficiency. This page compiles peer-reviewed research studies and scholarly articles that investigate the applications, methodologies, and implications of biotechnology in equine science.
Purification of follicle-stimulating hormone from horse anterior pituitary glands. Fresh horse-pituitary glands were extracted with 40% ethanol and the gonadotropins were recovered by increasing the alcohol concentration to 85% followed by drying with acetone. This preparation was further extracted with water at pH 5, and the extract was adjusted to pH 7 and lyophilized. The follicle-stimulating hormone in the pH-5-souluble fraction was purified by zone electrophoresis and resolved into six components by starch-gel electrophoresis. One of these components contained follicle-stimulating hormone which was recovered in the elution cell and the contaminating starch was separated...
Adaptation of equine abortion virus to Earle’s L cells in serum-free medium with plaque formation. The research article discusses the successful adaptation of the Equine Abortion Virus (EAV) to L-M 929 cells, the impact on infected cultures, and possible reasons for earlier unsuccessful attempts. It […]
Hysteroscopic insemination of small numbers of spermatozoa at the uterotubal junction of preovulatory mares. Mares were inseminated with motile spermatozoa suspended in 30-150 microliters Tyrode's medium directly onto the uterotubal papilla at the anterior tip of the uterine horn, ipsilateral to the ovary containing a dominant preovulatory follicle of > or = 35 mm in diameter, by means of a fine gamete intrafallopian transfer (GIFT) catheter passed through the working channel of a strobed light videoendoscope. Insemination of 10, 8, 25, 14, 11 and 10 mares with, respectively, 10.0, 5.0, 1.0, 0.5, 0.1 or 0.001 x 10(6) motile spermatozoa resulted in conception rates of, respectively, 60, 75, 64, 29,...
