The large orange text "MASTITE: o inimigo invisível" immediately grabs attention.

The video opens with a bright, cloudy sky background and the word "MASTITE:" in large orange letters. This transitions to "o inimigo invisível" (the invisible enemy) and an icon of a bucket. The text then explains that mastitis can cause a loss of over 500 kg of milk per cow per year. It then asks, "ALTA CONTAGEM de células somáticas?" (High somatic cell count?) and explains this means a loss of up to 3.7 kg of milk per day at the end of lactation. The ad then states that repeated mastitis can lead to a loss of up to 380 kg of milk in the following lactation. A megaphone icon appears with the text "VOCÊ SABIA" (Did you know?) and reveals that half of new infections occur during the dry period. The video then shows products: Orbenin DC and Teat Seal, with text explaining that the sealant creates a protective barrier and the antibiotic treats and prevents infections. The final scene shows cows and the products with the text "INVISTA EM PREVENÇÃO COM ZOETIS e veja a diferença na próxima lactação!" (Invest in prevention with Zoetis and see the difference in the next lactation!). The video ends with the Zoetis logo.
