name: The application of Near Infrared Transmittance (NIT) individual kernel sorting technology to improve grain quality from spring and durum wheat infected with Fusarium and the effects on broiler chicken performance and immune response.
description: This project investigated the use of new near infrared transmittance (NIT) technology for individual kernel sorting to reduce Fusarium damaged kernels (FDK) and mycotoxins in grain. There were two objectives: 1) determine the efficiency of sorting; and 2) assess how highly contaminated sorted grain fractions can be used in dietary challenges for broilers as a screen for methods to reduce mycotoxin exposure. Fusarium damaged kernels are associated with lower crude protein (CP) caused by fungal infestation during kernel development, and may contain varying concentrations of mycotoxins (e.g. deoxynivalenol; DON). The BoMill TriQ measures the NIT of limited spectra to predict CP variation among individual kernels at ~2 - 3 MT/hour. Five sources of downgraded grain attained from grain producers in Western Canada in 2013 were sorted into ten calibration fractions, each analyzed for CP, FDK and 16 common mycotoxins. From these analyses, three wheat sources were individually sorted into three test fractions: outliers (10%); high FDK (low CP; 20% of source); and low FDK (high CP; 70% of source). Four diet recombinations were produced based on increasing inclusion of the high % FDK fraction [0% (M0), 20% (M20), 40% (M40) or 60% (M60)] of each wheat source, providing increasing mycotoxin concentrations in the test diets. Productions of these diets from re-combining the FDK fractions enabled a 3 wheat source x 4 FDK level (M0, M20, M40, M60) factorial design. The 12 test diets were included at 70 (starter, 0 - 21 d) and 75% (grow/finisher, 21 - 35 d) of a basal diet. Diets were formulated to meet or exceed NRC (1994) requirements for broilers. Eight cages of five, one-day old male Ross 308 broilers were each randomly assigned to the 12 starter diets. The number of cages were reduced to three per diet at 21 d. Broiler performance were recorded for the 0 - 21 and 21 - 35 d. Apparent metabolizable energy (AME; kcal ME/kg diet) and nitrogen retention (NR; %) were determined using d…
