Sexual Reproduction
Term | Definition |
---|---|
progeny testing | a test of the value for selective breeding of an individual's genotype by looking at the progeny produced by different matings. |
donor cows | The cow that is having its sperm or eggs removed |
sperm | the male reproductive cell |
extenders | a substance added to a product such as paint, ink, or glue, to dilute its color or increase its bulk |
estrous cycle | comprises the recurring physiologic changes that are induced by reproductive hormones in most mammalian therian females. |
straws | an agricultural by-product, the dry stalks of cereal plants |
artificial vagina | device used to stimulate ejaculation in male cows. |
follicle stimulating hormone | a hormone found in humans and other animals. It is synthesized and secreted by gonadotrophs of the anterior pituitary gland. |
luteinizing hormone | a hormone produced by gonadotroph cells in the anterior pituitary gland. In females, an acute rise of LH triggers ovulation and development of the corpus luteum |
sire | the male parent of an animal, especially a stallion or bull kept for breeding |
motility | the ability to move spontaneously and actively, consuming energy in the process. |
artificial insemination | the injection of semen into the vagina or uterus other than by sexual intercourse |
embryo transfer | procedure that follows in vitro fertilization (IVF) and is often considered the simplest and final step of the in vitro fertilization process. The objective is to facilitate conception following fertilization from the in vitro fertilization procedure. |
quarantine | a medical term for the act of keeping an object in enforced isolation for a period of time to limit or prevent the spread of disease or infection. |
hormones | any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour. |
superovulation | also known as controlled ovarian hyperstimulation, is the process of inducing a woman to release more than one egg in a month |
dam | a barrier that impounds water or underground streams |
corpus luteum | is what is left of the follicle after a woman ovulates |
follicle | a small secretory cavity, sac, or gland, in particular. |
semen | an organic fluid that may contain spermatozoa. |
sperm sexing | used to produce offspring of the desired sex from a particular breeding in order to take advantage of difference in the value of males and females |
protectant | a substance that provides protection, e.g., against disease or ultraviolet radiation. |
ejaculation | the action of ejecting semen from the body |
gonadotropin releasing hormone | also known as luteinizing hormone-releasing hormone (LHRH) and luliberin, is a trophic peptide hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. |
recipient cows | the cow that receives the semen or egg |
flow cytometer | a laser-based, biophysical technology employed in cell counting, cell sorting, biomarker detection and protein engineering, by suspending cells in a stream of fluid and passing them by an electronic detection apparatus. |
conception | the action of conceiving a child or of a child being conceived. |
