6. Reproduction. more offspring leads to more feed costs - but is offset by reproduction numbers






7. Castration tool that uses a band around the testicles which cuts off circulation and eventually the testicles fall off






8. Cleans and lubricates the urethra ahead of the sperm. (if not - the urine in the urethra has a high salt content and would cause sperm to rupture and die)






9. Boars and stallions-> deliver semen directly into the cervix. bulls and rams-> deliver semen into the vagina.






10. FEED






11. Constitute 50-90% of the volume of the ejaculate. (3 glands total: seminal vesicles - prostate gland - cowper's gland)






12. (LH) stimulates the Leydig cells to produce testosterone






13. FEED






14. Duct through penis that carries sperm and urine






15. Important 'landmark' during palpation






16. 1. bring in new genes - 2. replace males with leg problems (difficulty breeding) Note: culling has a much greater emphasis in the dairy industry vs the beef industry.






17. Luteolysis happens because of the ____________ hormone






18. Examine accessory glands - also to know how big the pelvic opening is->heritable->relates to how much dystocia that bull's daughter has






19. (male) pushes the testes outward toward the legs for a cool-down off of the body






20. 1. bring in new genes - 2. replace males with leg problems (difficulty breeding) Note: culling has a much greater emphasis in the dairy industry vs the beef industry.






21. 19-23 (21) days






22. Examine accessory glands - also to know how big the pelvic opening is->heritable->relates to how much dystocia that bull's daughter has






23. Look for infection - split - and rupture of the penis






24. (male) definition: duct located outside of the testes. 3 parts: head - body - tail. 4 Functions:concentrate sperm - store sperm - transport sperm - site of sperm maturation. entire process takes ~40-60 days






25. When are dairy cattle dehorned?






26. Contains and regulates the temp of the testes for sperm production






27. What helps regulate spermatogenesis?






28. 2 month growth cycle. stored in the epididymis of the bull






29. 19-23 (21) days






30. Provide nourishment for the developing sperm






31. % of fat in milk. makes cheeses and ice cream. regulates cost of milk






32. Actual heat cycle (period)






33. Front feet and head first. (except for hogs and dogs)






34. Completes uterine growth initiated by estrogen and prepares the uterus for nourishment of developing embryo if pregnancy occurs - supports pregnancy by maintaining quiescent state of reproductive tract and suppresses mating behavior - prevents ovulat






35. (from Jersey Islands in Great Britain) Smallest cow - least milk - highest butterfat %






36. Animal which has been castrated after puberty






37. ~305 days (altough often longer due to breeding difficulties)






38. Located directly in front of the cervix. fertilized egg implants here. connected to two uterine horns. implantation occurs on the same side as ovulation occurred.






39. Birthing process (termination of gestation)






40. What makes the milk flow through the mammary glands?






41. (LH) causes female's egg to break (her period)






42. Depository for semen during insemination. where urine leaves the body






43. 1. sperm is not implanted in egg until hours after breeding. 2. fetal growth has not yet finished.






44. Front feet and head first. (except for hogs and dogs)






45. Male on one pin and female on other side






46. Cycle that lasts weeks (ovulation->hormone cycles->ovulation)






47. Produce testosterone. located between the seminiferous tubules






48. Organ of copulation - provides passageway for semen and urine - muscular organ characterized especially by its spongy - erectile tissue that fills with blood






49. Contains and regulates the temp of the testes for sperm production






50. Animal which has been castrated after puberty
