White Lupins and Triticale as Feedstuffs in Diets for Turkeys

Two experiments were conducted to determine the feeding value of white lupins (Lupinus albus) and triticale for Nicholas Large White turkeys using a corn-soybean meal type diet as a control. Diets were formulated to have equal amounts of specified nutrients per unit of metabolizable energy. Growth of male turkeys 0 to 3 weeks of age was similar to the control group when 15% white lupins were included in the diet. When white lupins were included at 30, 45, or 60% of the diet, growth was significantly depressed to 94, 89, or 85% of control, respectively. When triticale replaced corn there was a 6% increase in growth, which was nearly significant. Growth of female turkeys 8 to 12 weeks of age fed diets where white lupins supplied 20% of supplemental (soybean) protein was similar to turkeys fed control diets. When white lupins provided 30, 40, or 100% of supplemental protein, gains were 94, 95, or 85% of control, respectively (significant depressions). True metabolizable energy values for white lupins and triticale were 2641 and 3306 kcal/kg, respectively. Amino acid profiles for white lupins and triticale are given.
