Also found in: Dictionary, Thesaurus, Encyclopedia.
the complex system consisting of the male or female gonads, associated ducts, and external genitalia dedicated to the function of reproducing the species.
The bodily system concerned with reproduction, especially sexual reproduction, including in mammals the gonads, associated ducts, and external genitals.
the male and female gonads, associated ducts and glands, and external genitalia that function in the procreation of offspring. In women these include the ovaries, fallopian tubes, uterus, vagina, clitoris, and vulva. In men they include the testes, epididymis, vas deferens, seminal vesicles, ejaculatory duct, prostate, and penis. Also called genital tract, genitourinary system, urogenital system.
reproductive systemThe female organs and related structures, including hormones, which are directly involved in producing eggs and conceiving foetuses.
subserving or pertaining to reproduction.
see sexual behavior.
in all mammalian species other than humans the reproductive cycle is an estrous cycle.
fertility or efficiency in terms of input, e.g. services per conception, bull serving capacity estimates.
infertility; failure to produce viable offspring; the end-stage of reproductive inefficiency.
a pre-mating examination of cows in an intensive herd health program; includes manual examination of genitalia per rectum, cervical sample for microbiological examination, blood sample for locally relevant abortogenic diseases, manual examination of udder, milk cell count and composite bacteriological examination of milk.
computerized or card-based record of individual cow's complete breeding record including all services and identity of donor or naturally mated bull.
reproductive organs (female)
the ovaries, which produce the ova, or eggs; the uterine tubes; the uterus; the vagina, or birth canal; and the vulva, comprising the external genitalia. The udder is a secondary sex character, enclosing the mammary glands.
reproductive organs (male)
the testes, external genitalia and accessory glands that secrete special fluids and the ducts through which these organs and glands are connected to each other and through which the spermatozoa are ejaculated during coitus.
the productivity of the animal or herd or flock in terms of offspring produced, can be expressed in many ways, e.g. live piglets per litter or per year or per sow-year or per cubic meter of shed space.
viable, full-term offspring produced per female per year.
the end of cyclic reproductive activity in primates; not recognized in domestic animals.
the genital tract plus the endocrinal control systems, especially the hypothalamus, pituitary, gonads and placenta, the products of pregnancy and the mammary glands.
