I have a two year old goat who has mastitis in on teat. My vet recommended I try 'TODAY' first before having to be called out for an expensive vet visit. My husband purchase two tubes of Today which they gave him a discount because the tubes I guess expired in 10/2017. They told him at the feed store they are good up to 5 years after the expiration date. 1. IS THIS TRUE? 2. CAN I USE THIS ON HER BECAUSE NOW NO ONE IS OPEN TILL MONDAY? The tube is Today expiration 10/2017 . NDC#0010-4717-01 . Cephapirin sodium Also do I need more than one treatment of this? I understand I have to completely milk her out before giving this to her. I am not sure what else to write about this just that I need an answer whether it is safe to use this on my 2 year old goat... ………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..…... …... …………………………………………... ……... …... …... …………... ……... …………... …... ……... …...
