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






12. 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






13. The more stressed out the male is - the less sperm he is going to produce






14. Implies the amount of estrogen production






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






16. 265-285 days

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






23. 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. Castration tool which clamps down on the vans deferens. causes the sperm to not reach the penis to be ejaculated






36. Pulls sperm and egg together - gets body ready for pregnany - stimulates growth cells - develops mammary glands - starts to deposit fat.






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