The aim of the study was to determine whether the level and form of Cr in the diet of chickens influences its accumulation in tissues as well as intestinal absorption of P and its deposition in tissues. The experiment was carried out on 405 one-day-old male Ross 308 chickens that were randomly divided into five treatment groups. Control group was fed the diet without supplemental chromium; experimental groups were fed the diet with 3 or 6 mg/kg chromium picolinate (Cr-Pic) and with 3 or 6 mg/kg chromium nanoparticles (Cr-NP). Chromium was found to accumulate in the tissues of the ileum, liver, breast muscle, bones skin and in feathers of chickens. Chromium deposited in the ileum of chickens does not affect the ex vivo estimated intestinal absorption of P. The use of Cr in the diet of chickens carries the risk of lowering P levels in femur.

该研究的目的是确定鸡肉饮食中Cr的含量和形式是否影响其在组织中的积累以及肠道对P的吸收及其在组织中的沉积。实验是对405只1日龄雄性Ross 308鸡进行的，这些鸡被随机分为五个治疗组。对照组饲喂不含铬的饮食。实验组在日粮中饲喂3或6 mg / kg的吡啶甲酸铬（Cr-Pic）和3或6 mg / kg的铬纳米颗粒（Cr-NP）。发现铬会积聚在回肠，肝脏，胸肌，骨骼皮肤和鸡的羽毛中。沉积在鸡回肠中的铬不会影响离体估计的肠道P吸收。在鸡的饮食中使用Cr会降低股骨中P的含量。
