• Abstract:  The management with calves is the most important activity in dairy cattle, as the adoption of good practices ensures the development of calves for a promising future. Topics will be discussed such as the panorama of dairy cattle in Brazil, and the importance in raising calves. For the research, two calves were used. Calf 1 of the Holstein breed is the product of crossing a Holstein cow with a Holstein bull. Calf 2 is a cross between a Holstein cow and an Angus bull. One of the animals was in a collective pen, while the other had an individual pen, it was observed that this had no redundancy for changing the weight of the animals. Management with only one person in charge was more constant and ensured adequate monitoring of the calf, while the rotation of the team made it difficult to organize. It is concluded that the method of breastfeeding in the amount of 10% of live weight has a better efficiency compared to the amount of 4 liters of milk per day, disregarding the solid diet. In future work, the impact of variation in the supply of solid diet to calves can be evaluated.
