Daily activity patterns of Saanen goats in the semi-arid northeast of Brazil
The objective of the study was to characterize the daily feeding activity patterns of Saanen goats (Capra hircus) as a function of changes in climatic variables. The investigation was conducted in the municipality of Cruzeta, 300 km from the city of Natal, Brazil. Seventeen free-ranging female Saanen goats were selected for observation, wherein they were kept on a pasture with native vegetation and also received concentrated feed in a trough. Observational records of behavior on pasture were collected using focal animal and scan sampling for these specific behaviors: ruminating while standing or lying down, standing idly or lying down, walking, grazing and eating. Eating was the predominant activity observed. The frequency of some behaviors changed in accordance with certain climatic variables, with behaviors that require more active movement occurring in the morning hours, when temperatures are milder, exhibiting higher frequencies. These observations indicate that animals adjust their daily activities in order to minimize the effects of the stress caused primarily by environmental conditions.
