Figures & data

Table 1. Sample information used in present study.

Population	Number of samples	Place or habitat (elevation)
Tibetan chicken	6 Tibetan chickens	Conservation farms, Garzi Tibetan Autonomous Prefecture, Sichuan province (∼3100 m)
Tibetan chicken reared at low altitude	6 Tibetan chickens	Sichuan Agriculture University Poultry Breeding Farm, Sichuan Province (∼600 m)
Peng County yellow chicken	6 Lowland chickens	Sichuan Agriculture University Poultry Breeding Farm, Sichuan Province (∼600 m)

Figure 1. Relative expression levels of white blood cell (WBC) count (A) and red blood cell (RBC) count (B) in four chicken populations. Data are shown as the mean ± SE from six independent experiments. The bars without the same letter indicate differences significant at p < .05. TC: Tibetan chicken; LTC: Tibetan chicken reared at low altitude; LC: Peng County yellow chicken; HLC: Baoxing native chicken reared at high altitude.

Figure 2. Relative expression levels of haemoglobin (HGB) (A), mean corpuscular haemoglobin (MCH) (B) and MCH concentration (MCHC) (C) in four chicken populations. Data are shown as the mean ± SE from six independent experiments. The bars without the same letter indicate differences significant at p < .05. TC: Tibetan chicken; LTC: Tibetan chicken reared at low altitude; LC: Peng County yellow chicken; HLC: Baoxing native chicken reared at high altitude.

Figure 3. Relative expression levels of haematocrit (HCT) (A), mean cell volume (MCV) (B) and variable coefficient of red cell distribution width (RDWc) (C) in four chicken populations. Data are shown as the mean ± SE from six independent experiments. The bars without the same letter indicate differences significant at p < .05. TC: Tibetan chicken; LTC: Tibetan chicken reared at low altitude; LC: Peng County yellow chicken; HLC: Baoxing native chicken reared at high altitude.
