![]() If a teaser bitch is not available, many dogs will respond favorable to swab scent from an estrous bitch. Minitube microscope parts manual#Some males may not require any external stimulus beyond manual massage to attain erection. You will need a dog handler, a bitch handler, a estrous teaser bitch (optimally), collection cones, nonspermacidal lubricant, 15-ml conical centrifuge tubes, a microscope, microscope slides, coverslips, bulb pipettes, stain, a means to determine sperm cell concentration (hemacytometer or Spermacue™) and other supplies depending upon the purpose for the semen collection. Have all supplies and adequate personnel available. The dog needs to be relaxed and comfortable with the place and the people involved. In the typical setting, ejaculation in the dog is a voluntary process and cannot be forced or rushed. The collection process - tips for success When very young (12 years) sires are used for breeding, the American Kennel Club (AKC) requires documentation, including a semen evaluation, of the male's ability to sire a litter. In addition to artificial insemination breeding, collection of semen is indicated for evaluation in conjunction with a breeding soundness examination, in the diagnostic workup of potentially subfertile or infertile dogs, in the diagnostic workup of reproductive tract disease (infectious, degenerative or neoplastic disease), or for short-term (fresh-chilled extended semen) or long term (frozen semen) storage of gametes to be used in the future. The normal male can breed once every 2 - 5 days and maintain daily sperm output.Ī complete breeding soundness examination in the dog includes history-taking, general physical examination, reproductive system examination, libido determination, semen collection and evaluation, hormonal evaluation, and prostatic examination and testing for disease (eg. Males may successfully breed bitches prior to sexual maturity but they will not achieve maximal fertility or daily sperm output until mature. Sexual maturity is generally attained at 18 – 30 months. Like the compound microscope, these microscopes offer a high degree of magnification, but their resolution is much better.The normal male dog attains puberty at approximately 6 – 8 months of age. Its standard magnification is \(10\rm\) images, as well, by assembling multiple scans. The part is used to look through the microscope. These parts include:Įyepiece – It is situated at the top of the microscope and is also known as the ocular. The optical parts of the microscope are used to view, magnify, and produce an image from a specimen placed on a slide. Some high-quality microscopes have an articulated microscope arm with more than one joint allowing more movement of the microscopic head for better viewing. It gives support to the head of the microscope and is also used when carrying the microscope. It also carries microscopic illuminators.Īrms – The microscope arm connects the base and the head and the eyepiece tube to the microscope base. Head – This is also known as the body it carries the optical parts in the upper part of the microscope.īase – It acts as microscopes support. There microscope anatomy includes three structural parts, i.e. ![]() For greater magnification than this, scientists generally use electron microscopes. Minitube microscope parts professional#Most compound microscopes can magnify by \(10,20,40,\) or \(100\) times, though professional ones can magnify \(1000\) times or more. Minitube microscope parts series#Each of these may be made up of a series of different lenses. There is a lens above the object (called the objective lens) and another lens near your eye (called the eyepiece or ocular lens). Microscopes used in schools and professional laboratories are compound microscopes and use at least two lenses to produce a magnified image. The simplest microscope is a magnifying glass made from a single convex lens, which typically magnifies by about \(5 – 10\) times. Microscopes are effectively just tubes packed with lenses, curved pieces of glass that bend (or refract) light rays passing through them. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses. Therefore, a microscope is an instrument used for looking at objects that cannot be seen with the naked eye, and microscopy is the science of using a microscope.Ī microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The word microscope is derived from the Greek “mikros”, meaning small and “skopein”, meaning to see. CLEAR YOUR CONCEPTUAL DOUBTS ON MICROSCOPE What is a Microscope? ![]()
