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 includesdifferentaspectsrelatedtohealthandanimal
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 these animals 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 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. The change in the milking routine and change the type of used
milking can bring behavioral changes with influence on productivity. However, the
two races presented behaviorally extreme docility that was reflected in an easy
adaptation to the new proposed milking system, without compromising the
productive aspects. |
