Weaning, travel, or a upsetting change can cause stress.
Those of us that have been in the goat breeding industry for a while have seen the undesirable results of the cause of stress. How it plays a destructive decline in the immune system and can set our goats up for all sorts of unhealthy situations. Stress can even kill.
I have found Organic herbs to be very beneficial to relax me and my goats in a very natural and healthy way without any bad side effects. They are economical with two simple flowers. Chamomile and Lavender. You can feed directly 2 teaspoons each as top coat to your does that you are weaning kids off. The kids you can make a tea by boiling water then pour it over a 1/4 cup each, let seep for 8 minutes. Cool strain and pour into a quart jar. Give 6 ml to kids that are being weaned. It relaxes both dams and kids, no crying, no stress, no illness, making the weaning process, oh so much nicer for everyone.
