| The aim of this study was to establish the blood profile of native chicken in Taiwan. Two batches of chicks, hatched in September and January, respectively, were used to determine the RBC, PCV, Hb levels in whole blood, and the levels of calcium, total protein, albumin, and cholesterol in the serum from 4-wk to 30-wk of age.
In general, the effects of hatch season, age and sex were significant in RBC, PCV, and Hb. A higher concentration of RBC and Hb were found for chicken hatched in January. Before 16-wk of age, the hematological values increased with the increase of age.
The calcium concentration were kept stable after 6-wk of age. By the time of sexual maturity, the calcium and total protein levels were also higher significantly. Higer total protein levels were observed for chicken hatched in January. The total protein and albumin levels rose slightly as the age increased and reached the peak in 20-wk of age. The cholesterol level varied significantly among different ages and individuals and reached its peak at 6-wk, and dropping after 16-wk.
