Synthetic Amino Acid Supplementation of Triticale and Wheat Based Diets for Growing-Finishing Pigs
Dietary supplementation of feed grade synthetic amino acids may be more advantageous for diets based on triticale (X Triticosecale Wittmack) or soft red winter wheat (Triticum aestiuum) than maize (Zea mays L.) for growing and fmishing pigs (25 to 109 kg). Four trials, involving 190 pigs, were conducted to evaluate the effectiveness of supplementation of triticale and wheat based diets with synthetic lysine and threonine for growing and finishing pigs. Substantial replacement of supplemental protein (soybean meal) with synthetic lysine and threonine did not affect pig growth or carcass lean content (P>.10). In fact, complete or nearly complete replacement of soybean meal occurred for finishing pig (55 to 109 kg) diets formulated with triticale.
