Effect of dietary chromium tripicolinate on productivity of sows under commercial conditions

摘要

Twelve 4,000-sow units were assigned to one of two dietary treatments (0 or 200 ppb supplemental Cr from chromium tripicolinate) to further examine and clarify the effect of supplemental chromium (Cr) from chromium tripicolinate on productivity of sows in commercial conditions. Following a 6-month loading period, reproductive performance was evaluated over a 12-month test period. Analysis of more than 50,000 litters per treatment revealed that dietary supplementation of 200 ppb Cr from chromium tripicolinate had a positive impact on sows bred within 7 days postweaning, number of pigs born live and weaned, and sow mortality. Because the use of a biologically available form of Cr can positively affect total sow productivity and allow greater animal output with no fixed capital inputs, it has the potential to improve total enterprise profitability.
