A descriptive study of dairy goat predation in Louisiana.
Questionnaires concerning herd size, housing and management, and previous instances of predation were mailed to 124 goat owners in Louisiana. Postcards were mailed over a period of one year on a monthly basis, to the 84 individuals who responded to this questionnaire. Owners were asked to indicate whether they had seen predators on their property and whether any goats were injured or killed by the predators. Upon receipt of any postcard with a "yes" answer to either of these questions, a telephone interview was conducted to determine the exact circumstances of predator experience. The interview format included time, physical circumstances, and detailed questions about the actions of the predator and the goats. In 85% of the cases, the predators sighted were reported as dogs, and most of these were thought to be pets, rather than wild. Instances of attacks occurred most frequently during periods of reduced light. No clear seasonal pattern of attacks emerged. Four management factors were associated with a reduction in number of attacks; penning the goats at night, use of a night light, proximity of the herd to an occupied residence, and presence of a dog.
