Abstract |  Download PDF | |  Post | Background:
Indigenous horses in South Sulawesi are valuable genetic resources with important socioeconomic roles and notable adaptation to tropical heat, which is increasingly relevant under thermal stress induced by climate change.
Aim:
This study aimed to provide preliminary findings on the hematological profile and heat tolerance of indigenous horses reared in South Sulawesi, Indonesia.
Methods:
The observed variables included microclimatic conditions, physiological parameters, heat tolerance index (HTI), and hematological profiles. This experiment was conducted using a cross-sectional observational design with 3 regional treatments and 5 replicates per treatment. The hematological parameters were analyzed using an automated hematology analyzer (Prokan PE-6100 Vet).
Results:
Most hematological parameters did not differ significantly among regions. However, hematocrit (HCT) values were significantly lower (P
