Effects of Corn Naturally Contaminated with Aflatoxins on Performance, Calcium and Phosphorus Metabolism, and Bone Mineralization of Broiler Chicks

  The objective of this study was to investigate the effects of corn naturally contaminated with low levels of aflatoxins (AF) on performance, calcium (Ca) and phosphorus (P) metabolism, and bone mineralization in broilers. Four hundred and fifty 1-d-old male broiler chicks were randomly allotted to... Full description

On d 42, the increasing AF intake level linearly decreased (P<0.05) TBS, and the percentages of Ca and P in tibia. These results indicated that the low level of AF intake had negative effects on the P metabolism and bone mineralization of broilers at exposure of 42 days, which might relate to the changes in vitamin D and PTH metabolism.

abstract  The objective of this study was to investigate the effects of corn naturally contaminated with low levels of aflatoxins (AF) on performance, calcium (Ca) and phosphorus (P) metabolism, and bone mineralization in broilers. Four hundred and fifty 1-d-old male broiler chicks were randomly allotted to control (no AF), and the diet with the corn contaminated with AF as a substitute for 50% or 100% of the corn in control (HAC or AAC). The broilers in HAC and AAC were administered with 6.5-8.0 and 13.0-16.0 μg AF/kg BW per day respectively in overall period (1-42 d). Ten birds per treatment were selected at d 43 to explore the apparent digestibility of Ca and P using all excreta collection method after 2 days adaptation. The AAC diet reduced (P0.24) on the apparent digestibility of Ca and P. The increasing AF intake content linearly increased (P0.10) the percentages of ash, Ca and P in tibia. On d 42, the increasing AF intake level linearly decreased (P<0.05) TBS, and the percentages of Ca and P in tibia. These results indicated that the low level of AF intake had negative effects on the P metabolism and bone mineralization of broilers at exposure of 42 days, which might relate to the changes in vitamin D and PTH metabolism.
