Weather and shade effects on cow corral activities

Area of Science:

• Animal Science
• Environmental Management
• Behavioral Science

Background:

• Cattle welfare and productivity are influenced by environmental conditions, particularly heat stress.
• Shade availability is a critical factor affecting animal behavior and physiological responses in confined feeding operations.

Purpose of the Study:

• To evaluate the impact of different shade structures and weather conditions on the activity and feeding behavior of cows in corrals.
• To assess the effectiveness of various shade designs in mitigating heat stress and improving animal welfare.

Main Methods:

• Utilized visual scanning at 15-minute intervals to monitor cow activities in corrals under varying shade conditions and weather types.
• Quantified feed intake, resting behavior, and water consumption in relation to shade provision and ambient temperature.

Main Results:

• Complete ration intake decreased by 13% in hot weather compared to cool weather in unshaded corrals.
• Hot afternoon fresh-feed intake was reduced by 14% in unshaded and 46% in strip-shaded corrals with unprotected mangers.
• Cows with comprehensive shade over resting and feeding areas showed doubled and tripled feed intake compared to those with unprotected mangers, especially in hot weather.
• Increased ambient temperature led to a linear increase in cows resting or ruminating while standing, particularly in unshaded or poorly shaded conditions.
• Water intake and trough lingering increased in hot weather for unshaded cows.

Conclusions:

• Effective shade design, especially covering feeding areas, is crucial for maintaining adequate feed intake and reducing heat stress in cattle.
• The observed behavioral changes highlight the importance of shade provision for animal welfare and productivity in agricultural settings.
• The visual scanning method is a practical and easily teachable tool for monitoring cattle behavior in extension education programs.
