5. Effects of Hunting Activities on Erythrocytes Counts, Hemoglobin Concentration and Haematocrit Value of Local Dogs (Canis familiaris) In Tabek Panjang, Baso Subdistrict, West Sumatera

dy aimed to determine the effect of physical activities such as hunting, to erythrocytes, hemoglobin, and haematocrit value in local dogs of Tabek Panjang, Baso Subdistrict, West Sumatra. Samples in this research were 10 male hunter dogs with 2-2,5 years old and 15-18 kg. Blood samples were collected two times, one day before and one day after hunting from the same animal. The samples were analyzed in Parasitology Laboratory, Balai Veteriner Bukittinggi, West Sumatera by using hematology analyzer (exigoeos vet Boule Medical, Swedia). The data was analyzed statistically using  a T-test. The results showed the average number of erythrocytes before hunting was 6,05 ± 0,67 x 10 6 /µL and after hunting was 5,15 ± 0,79 x 10 6 /µL. Hemoglobin concentration before hunting was 13,01 ± 0,40 g/dL and after hunting was 12,20 ± 0,48 g/dL. Hematocrit value before hunting was 36,19 ± 1,09% and after hunting was and 35,43 ± 1,14%. It can be concluded that all data decreased significantly after hunting (P<0.05), the decrease in erythrocytes, hemoglobin concentration and hematocrit value after hunting activity was a normal response of the body to maintain physiological conditions.
