Objective: To further examine and clarify the effectof supplemental chromium (Cr) from chromium tripicolinate on productivityof sows (especially litter size) under commercial conditions.
Methods: Based on reproductive performance during a3-month "pretest" period, 12 4000-sow units were assignedto one of two dietary treatments: either to a "+Cr"group that received 200 ppb supplemental Cr from chromium tripicolinate,or to a "Control" group that received a standard commercialration without supplemental Cr. After a 6-month "loading"period, reproductive performance was evaluated over a 12-month"test" period.
Results: Dietary supplementation of 200 ppb Cr fromchromium tripicolinate had a positive impact on sows bred by 7days postweaning, number of pigs born alive and weaned, and sowmortality.
Implications: The use of a biologically available formof Cr can positively affect total sow productivity and allow greateranimal output with no additional fixed capital inputs. This hasthe potential to improve total enterprise profitability.
