Implementation of nutrient kinetics concept in formulation of pig’s starter feed

Resumen

Objective: To compare a conventional starter feed (Milkiwean®) with a starter feed formulated under the concept of digestion and absorption kinetics of nutrients (Milkiwean Kinetio®) in piglets.

Methodology: A total of 440 piglets (initial body weight 6.4 ± 0.83 kg and 22 days of age) were randomly assigned following a completely randomized design. The experimental treatments consisted of evaluating two starter diets: Milkiwean® and Milkiwean Kinetio®.

Results: Pigs fed the standard diet exhibited greater body weight gain, final body weight, and feed intake (P = 0.08); however, feed conversion ratio was significantly improved with Milkiwean Kinetio® (P = 0.001). Additionally, the cost per kilogram of pork produced was lower with Milkiwean Kinetio®.

Implications: Further research is needed on the synchronization of digestion and absorption of nutrients from dietary ingredients used in pig production.

Findings/Conclusions: Formulating pig diets based on the kinetics of nutrient digestion and absorption has the potential to enhance nutrient utilization.
