ABSTRACT
Appropriate strategies are required for the alleviation of heat stress resulting from global warming contributing to impaired metabolism and dysregulated immune and reproductive functions in animals. The aims of the current study were to investigate modulation impacts of moringa oleifera on thermo-tolerance parameters and blood indices in subtropical ewes under heat stress. Eighteen ewes with an average weight of 50.3 ± 1.80 kg and aged 2.5 - 3.0 years were randomly allocated into three equal groups (six/group). The 1st and 2nd groups were assigned to Moringa oleifera treatments up to 50 and 100 g respectively and the 3rd group was used as a negative control. The 1st and 2nd groups were subjected to heat stress for three hours from 12:00 to 3:00 pm for three consecutive days. Before and after heat stress; thermo-tolerance parameters (rectal temperature, respiration rate, pulse rate, and partial pressure of oxygen (SPO2) were recorded, as well as, blood samples were collected and analyzed for hematological parameters and plasma biochemistry parameters. The results indicated that heat stress negatively influenced the thermo-tolerance, hematological, and plasma biochemistry parameters. M. oleifera alleviated the negative effects of heat stress, as well as modulated thermo-tolerance responses, metabolites, and liver and kidney functions. M. oleifera supplementation with a rate of 50 and 100 g to stressed ewes especially during high ambient temperatures and in subtropics is recommended.
