GasX is a treatment for gas in people. You find it in the grocery store or the drug store where medicines are found. CD/T is a vaccine for clostridium perfingens and tetanus. I gave my kids a shot shortly after they were born and ten one every three weeks or so until they were three months old. Then they got a booster once a year. I happened to live in an area of California where entero was very common, probabbly because of the pH of the soil. Clostridium perfingens causes enterotoxemia. It can strike any goat at any time without warning and can kill in a matter of hours. All goats should be vaccinated for it.
