Abstract
Many Caribbean small ruminant management systems are forage-based, relying on rain to sustain pastures for feed. Animal performance is thus heavily dependent on forage availability. The nutritive value of pasture was highest during the intermediate season and lowest during the dry season, leading to under nutrition, and declined flock performance in the dry season. Climate change will therefore seriously hamper pasture availability and nutritive value. Hair sheep on pasture, without shade or water, experienced increased respiration rate, they were under chronic heat stress. However, where adequate shade and water were provided, heat stress was reduced. The current system of small ruminant production is prone to the negative impacts of climate change events due to its effect on nutrition, growth and reproduction. Immediate actions are needed to prepare farmers to respond by mitigation methods, to maintain and enhance animal productivity if the envisaged protein security goals set for this sector are to be realized.
