SUMMARY The modern broiler chicken industry is connected with various disorders of the skeletal system. The fast-growing birds by increased weight gain often have leg problem which leads to economic losses. The correct bone development of broilers is highly correlated with calcium and phosphorus ratio (about 2:1) so providing these macroelements with diet seemed to be fundamental. The most common inorganic sources such as limestone, mono- and di-calcium phosphates are commonly used nowadays. The doses in feed generally are in the range of 6–6.5 g/kg for Ca and 2–3.5 g/kg for P, depending on the supplementation of phytase. However, the bioavailability of inorganic sources is poorer than organic sources. This fact is important in reference to their impact on the environment. Because of the continuous search for alternative sources of calcium or phosphorus, with better bioavailability due to, for example, their size, the scientific area of nanotechnology arouses increasing interest. It is well-known nanoparticles have a great potential even at very low doses. Some research focused on calcium-phosphorus compounds already demonstrated no negative effect on birds’ health, improvement in production results and bone quality, opportunity to use lower dosages of nano sources and decreasing content of Ca and P in excreta (by ca. 50%). Thus, this aspect may be the new trend during the next years. However, the further studies should be performed.

家禽营养中的钙和磷及其纳米颗粒形式

总结 现代肉鸡产业与骨骼系统的各种疾病有关。因体重增加而快速生长的家禽通常会出现腿部问题,从而导致经济损失。肉鸡的正确骨骼发育与钙磷比例(约 2:1)高度相关,因此在饮食中提供这些常量元素似乎是基础。最常见的无机来源,例如石灰石、磷酸一钙和磷酸二钙,现在普遍使用。饲料中钙的剂量一般在 6-6.5 g/kg 和磷的 2-3.5 g/kg 范围内,具体取决于植酸酶的补充。然而,无机源的生物利用度比有机源差。考虑到它们对环境的影响,这一事实很重要。由于不断寻找钙或磷的替代来源,例如由于它们的大小而具有更好的生物利用度,纳米技术的科学领域引起了越来越多的兴趣。众所周知,即使在非常低的剂量下,纳米颗粒也具有巨大的潜力。一些专注于钙磷化合物的研究已经证明对鸟类健康没有负面影响,改善生产结果和骨骼质量,有机会使用较低剂量的纳米来源,并降低排泄物中钙和磷的含量(约 50%) . 因此,这方面可能是未来几年的新趋势。但是,应该进行进一步的研究。众所周知,即使在非常低的剂量下,纳米颗粒也具有巨大的潜力。一些专注于钙磷化合物的研究已经证明对鸟类健康没有负面影响,改善生产结果和骨骼质量,有机会使用较低剂量的纳米来源,并降低排泄物中钙和磷的含量(约 50%) . 因此,这方面可能是未来几年的新趋势。但是,应该进行进一步的研究。众所周知,即使在非常低的剂量下,纳米颗粒也具有巨大的潜力。一些专注于钙磷化合物的研究已经证明对鸟类健康没有负面影响,改善生产结果和骨骼质量,有机会使用较低剂量的纳米来源,并降低排泄物中钙和磷的含量(约 50%) . 因此,这方面可能是未来几年的新趋势。但是,应该进行进一步的研究。
