I hope I'm correct in assuming that Lysigin needs a booster after 21 days of initially administering. Can you give a "booster" to a potentially bred doe? Also, a timing and cooling question...20 minutes to milk out 3 goats. immediately put filtered milk into quart containers and place in pot filled with water and ice and put in the freezer. 30 minutes later the milk still is not at 40 degrees. No matter what I do I can't seem to get the milk to cool quick enough. The milk tastes fine and all, just trying to handle the fragality (is that a word? :blush) of the milk according to the goat milk gospel.
