RESUMO:

The studies related to animal behavior have increased in recent years, and are important because they allow better understanding of the causes that guide the actions of the animals and allow for better planning in the implementation of more efficient production systems. Adding to this, the animal welfare has received increasing attention in the technical, scientific and academic means. The main reasons that lead people to be concerned with the farm animals welfare are concerns of ethnic origin, the potential effect it may have on productivity and quality of food and the links between animal welfare and international trade its products of animal origin. The study of the welfare is shown as complex and includes different aspects related to health and animal behavior and interactions that occur between these aspects. The dairy farming is a sector of animal production in which the human-animal interaction is of fundamental importance because of contact that establishes daily in carrying out routine activities. Among the factors that affect the behavior of cattle and buffaloes, stand out food, the weather and the adopted production system. For lactating animals, the number of milkings, production and time of milkings are key conditions in their behavior patterns. Currently, the dairy Gir is the second breed in official milk control in Brazil, the first Brazilian zebu and dairy breed in the world. The Gir has established itself as breed adapted to the conditions of tropical Brazil, with good productive results. The Gir, as well as other Zebu breeds, tolerate higher ambient temperatures and can be managed in regions with these temperatures without severe impairment of milk production. Regarding the buffalo, one of the main points stand out this animal is the fact that the cost of production in general is not far from both the cost of cattle, as well as great adaptability to almost any kind of weather. In Brazil four breeds are recognized, and the Murrah used in this research. The Murrah buffalos can be created in various weather conditions, often presenting as an option for the areas of use of the property to which the cattle do not fit. The buffalo milk has a different composition compared to cow's milk, and provides an output of oil products with high commercial value. In this work, the Gir cattle and Murrah buffaloes were exposed to two different types of milking, manual milking and subsequently mechanical tandem milking for Gir and mechanical "espinha de peixe" milking and then milking carousel for Murrah buffalo. The change in the milking routine and change the type of used milking can bring behavioral changes with influence on productivity. The aim of this study is to describe the behavioral expression during routine milking in dairy cows of Gir and dairy buffaloes of Murrah and identify possible changes in the productive and nutritional characteristics of milk.
