I recently picked up 40 bales of kudzu hay. My 4 does share 2 flakes a day while my buck is separated during feeding time. (For those who don't know, kudzu in high in protein and calcium, very similar to alfalfa.) I have noticed, starting the day after the first taste of kudzu, that milk production went up and the amount of cream really increased to the point that it takes much longer to strain the milk. The taste of the milk is great! I paid $4/bale in comparison to the $15-20/bale that alfalfa sells for around here, with better results. From what the man I buy feed from tells me, the large amount of vines in the hay, which of course provides a lot of roughage, is what is increasing the cream production.
