Helping my dad calve his cows out and we've lost 3 calves because the cows can not get all the mucus off the calves nose and mouth area. Very thick and calves are suffocating. If we hadn't caught on we would have lost a 4th. But we were watching and had to assist the cow and wipe the calf's face off. Cows are licking calves and claiming them. Any idea as to why it's so thick and hard to clean off. Cow's had salt/mineral all year and 20% protein licks 6 weeks before calving. Thanks!
