3. Milk is 15% ________ and 85% __________.






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






5. (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






6. Animal which has been castrated after puberty






7. What about the sperm for a bull which has been castrated but still has testicles?






8. (male) Primary sex organ - produces sperm (male gamete) and male sex hormones - 2 total






9. Luteolysis happens because of the ____________ hormone






10. ~60 days before calving






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






12. Start of the reproductive tract for the female. located outside of the body






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






14. Microscopic - make sure not sterile - very few bulls are actually tested






15. Why Dairy calves are fed powdered milk.






16. Important 'landmark' during palpation






17. Animals which have many estrous periods during certain periods per year (ex: mare - ewe)






18. Urinary calculi.






19. 1. visual evaluation - 2. scrotal circumference - 3. penis and prepuce observation - 4. rectal palpation - 5. libido test - 6. semen evaluation






20. (FSH) helps to regulate puberty - needed every day - stimulates the sertoli cells to produce nutrients for the sperm






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






22. Hold the penis in the bulls body when not in use. releases penis before ejaculation or urination.






23. Gonadotropic (GnRH) is (FSH and LH). Follical Stimulating (FSH) and Lutinizing Hormone (LH).

28. 265-285 days






29. Important 'landmark' during palpation






30. Failure to have one testis (gonad) to descend






31. Sperm is produced here






32. 4-6 days






33. Indicator of sperm production. the bigger the scrotal circumference the bigger volume of sperm because more seminal vesicles available to produce the sperm






34. 19-23 (21) days






35. 114 days






36. Larger the cow - more milk is produced; smaller the cow - less milk is produced






37. 1. reproduction - 2. mastitis/udder problems - 3. low milk production - 4. soundness/poor feet and legs (living on concrete)






38. 1-3 days






39. Not being bred back into herd. horses are seasonal breeders vs. cows as anytime breeders






40. Supply nutrients for the sperm following ejaculation and deposition into the female reproductive tract






41. Way to know everything is alright with the breeding male






42. To remove/separate testicles from animal's body before animal reaches puberty






43. Allows extension of penis without fibro-elastic penis






44. (switzerland) 2nd in size and milk production - most muscle -






45. FEED






46. Way to know everything is alright with the breeding male






47. Duct through penis that carries sperm and urine






48. Earlier you castrate a male - the easier it is on the animal. the longer you wait - death rates increase

50. BST given to dairy cattle makes the mammary gland more persistent - helps produce more milk. good as Long-term because it does not cause cow to bulk up - provides more milk/cow Which means less cows needed - less cows need to be given feed - lower co
