The Physiological values of Brahman Cross cattle raised in feedlot located in tropical low land
Keywords:
Brahman cross cattle, Tropical low land, Microclimate, HaematologyAbstract
The study was aimed to assess the health of Brahman cross cattle raised in the feedlot located in the tropical low land. This study used a total of twelve imported Brahman cross bull in the commercial feedlot located in Lampung lowland (50 m above sea level), with average temperature: 28.3 ± 4.0oC and the highest temperature at the evening: 31.3± 4.4oC. The total erythrocytes, haemoglobin concentration, total leukocytes, and differential leukocytes were within physiological reference range for cattle, except the haematocrit and neutrophils-lymphocytes ratio (NLR). The increased haematocrit and NLR is the adaptation to an increased temperature of environment in tropical low land area. In conclusion, the tropical low land condition affect the health status of Brahman cross cattle by an increased haematocrit and neutrophils-lymphocytes ratio.
