In the diet of calves, search for additives that aid in their development is essential due to impact these can generate throughout lives, resulting a relationship with longevity and maintenance herd. Yuca schidigera has been used ruminant diets, impacting health performance; however, there are few reports on its intake by dairy cattle rearing phase. Therefore, this study's objective was evaluate whether adding Yucca calves phase benefit health, productive performance, feed efficiency. The study conducted over 60 days, 24 divided into two groups: G1 had no added G2 188 mg per kg dry matter intake. Data samples were collected at 30-day intervals. No treatment effect observed body weight, weight gain, daily or (p > 0.05); showed 26.3% lower efficiency than those G1.
