Effects of a Feed Additive Premix Inclusion in diets of Varying Composition on metabolizable Energy, Standardized Ileal Digestibility of Amino Acids, and Growth Performance in Growing- finishing Pigs
Randomized trial examines feed additive impact on energy and amino acid digestibility in pigs, suggesting no performance enhancement.
Key Points
This research aims to evaluate the effects of a feed additive premix on the digestibility and growth performance of growing-finishing pigs across various diets.
Three experiments conducted on grow-finish pigs using 3 diet types (corn, sorghum, sorghum with DDGS) and 2 levels of FAP (0 or 0.13%)
Experiments involved analysis of energy metabolism and amino acid digestibility based on various diet and FAP combinations
Total of 360 mixed sex pigs housed in pens for growth performance measurement.
Addition of the feed additive decreased the apparent total tract digestibility of dry matter and gross energy in corn-based diets (P < 0.05).
Increased standardized ileal digestibility of certain amino acids was observed with specific dietary combinations but not overall performance (P < 0.05).
No significant differences in average daily gain or feed intake noted, suggesting the feed additive may not enhance overall pig performance.
