Alright we have discussed ages for castration, 4-6 months seems like the norm for those who feel this allows maturation of the urethra in order to decrease the chance for urolithiasis. My goats are now 6 months old and have now begun to smell well... I have noticed pack goats who look much more like bucks but yet are not intact, bulkier around the shoulders, longer horns and beards. I assumed they were castrated later. My question to our community of packers, are there advantages to wait yet longer before castration; perhaps yet a larger urethra and a stronger pack goat? How long do you have to wait to castrate to achieve a stronger pack goat, 9 months, one year or 18 months? I could put up with the stink and behavior a few more months if I could get a whether just bit bigger and stronger and possibly a lower chance for stones.
