摘要
Egg quality traits and some blood parameters of Bianca di Saluzzo hen (BSh) were compared to Isa Brown hen (IBh). Birds were reared in free range conditions. Weight of the whole egg was higher (P≤0.01) for IBh, due to its higher amount of albumen (P≤0.01) whereas BSh egg showed the highest weight and relative percentage of yolk (P≤0.01). IBh and BSh egg chemical composition was similar. Total red cells did not show statistical differences between groups, while total leucocytes were lower (P≤0.05) for BSh Heterophyl/Lymphocyte (H/L) ratio of BSh was lower (P hens. than IBh (0.33 vs. 0.82). IBh α-1 acid glycoprotein (AGP) mean concentrations were affected by time: the values registered after 15 d (T1) and 2 months (T2) of observation were similar (345±132 and 279±58 μg/ml r while AGP value registered after 4 months (T3) were significantly higher espectively), (700±487 μg/ml); BSh did not display any AGP statistical variation over time. IBh albumin mean concentration (1.62 g/dL) was statistically lower than BSh values (1.89 g/dL); in both groups no effect of time of sampling was recorded. Acute phase protein (APP) values of BSh suggested a more adaptive attitude to free range conditions and appeared more constant over time. The present findings suggest genetic or adaptive differences affecting egg quality, physiological and immunological parameters.

将Bianca di Saluzzo母鸡（BSh）的蛋品质特征和一些血液参数与Isa Brown母鸡（IBh）进行比较。鸟类在自由放养条件下饲养。全蛋重量较高（P≤0。01）对于IBh，由于其蛋白含量较高（P≤0.01），而BSh蛋显示最高的重量和蛋黄的相对百分比（P≤0.01）。 IBh和BSh蛋的化学成分相似。总红细胞组之间未显示统计学差异，而总白细胞较低（P≤0.05）BSh异体/淋巴细胞（H / L）比例较低（Phns。比IBh）（0.33 vs.0.82）。e：观察15天（T1）和2个月（T2）后记录的值相似（345±132和279±58μg/ ml r，4个月后（T3）登记的AGP值分别显着增加），（700±487μg/ ml）; BSh未随时间显示任何AGP统计变异。 IBh白蛋白平均浓度（1.62g / dL）在统计学上低于BSh值（1.89g / dL）;在两组中均未记录取样时间的影响。 BSh的急性期蛋白（APP）值表明对自由范围条件具有更自适应的态度，并且随着时间的推移看起来更加恒定。目前的研究结果表明影响鸡蛋质量，生理和免疫参数的遗传或适应性差异。 ≤0.01）
