We use 1/4-1/2 cup of conditioner with 1/2 cup vinegar mixed in 3 gallons of water. We completele wash and rinse the animal and then use the mix on them. We first dip the end of the tail and then stand behind them a pour it down their back and allow it to run down their sides. We DO NOT rinse this out. This is a sure fired way to return condition to their skin and also fend off dandruff.
The majority of the folks in our area use this method, especially on haired cattle.
