How do I correctly say that during my industrial training at the livestock unit, A pig farrowed 7 piglets. A vaccine was administered to the piglets days after birth (what is the name of the supplement that is usually given to piglets days after birth)

You can say: "During my industrial training at the livestock unit, a pig farrowed 7 piglets. The piglets were administered a vaccine a few days after birth." As for the supplement that is commonly given to piglets after birth, it is often iron supplement, specifically **iron dextran**, which helps prevent anemia. In some cases, piglets may also be given a multi-vitamin or glucose solution to support their health after birth. Here's the revised version including the iron supplementation: "During my industrial training at the livestock unit, a pig farrowed 7 piglets. The piglets were administered iron dextran a few days after birth to prevent anemia." Feel free to adjust it based on the specific supplement used in your case!
