Abstract
Previous studies have shown that the inclusion of medium chain fatty acids (MCFA) results in an improvement in nursery pig performance. Therefore, the objective of this study was to evaluate a proprietary C8:C10 MCFA blend (CaptiSURE, Kemin Industries, Inc., Des Moines, IA) on nursery pig performance. A total of 360 weaned piglets (initial BW = 6.1 kg) were randomly assigned to a control (no MCFA blend) or 10 kg/t MCFA blend (10 pigs/pen, 18 replicate pens/treatment), in which MCFA blend was substituted at the expense of tallow at a 1:1 rate. Diets were manufactured in 3 dietary phases (d 0–7, 7–21, and 21–42) in pelleted form. Due to an unintended bacterial challenge at the sow farm, pigs were treated with amoxicillin using a pulse protocol (48 hrs on / 48 hrs off) from placement to d 21. Data were analyzed using the students T-test procedure, and pen served as the experimental unit. Within dietary phase 2 (d 7–21), the inclusion of MCFA blend improved ADG (264g vs 326g, P = 0.017) and G:F (0.79 vs 0.89, P = 0.005), while exhibiting a trend to improve ADFI (330g vs 364g, P = 0.080). Within dietary phase 3 (d 21–42), the inclusion of MCFA blend improved ADG (518g vs 581g, P = 0.024) and ADFI (719g vs 799g, P = 0.006). Overall (d 0–42), the inclusion of MCFA blend improved ADG (379g vs 438g, P = 0.007), ADFI (503g vs 0.562g, P = 0.009), and G:F (0.75 vs 0.78, P = 0.042), resulting in a 2 kg heavier pig (P = 0.043). In summary, the inclusion of a proprietary C8:C10 MCFA blend at 1.0% in nursery pig diets improved growth performance.
