 
 Caution urged when feeding DDGS, canola to broilers Feeding distillers’ dried grains plus solubles
or canola meal could impair performance
and carcass yield, investigators cautioned
at the International Poultry Scientific Forum
in Atlanta.In their controlled experiment, 1-day-old male heritage broilers were fed different levels of either distillers’ dried grains plus solubles (DDGS), canola meal or DDGS along with canola meal. The diets were formulated to be similar in calories and met the digestible amino acid requirements of broilers. Performance was evaluated up to 48 days of age and carcass characteristics were measured, said Byoungyun Jung, of the University of Georgia, and colleauges. Up to 12% DDGS in the diet, the maximum amount tested, did not significantly affect bodyweight gain or feed intake but negatively affected feed efficiency. Including 7.5% canola meal did not significantly affect feed efficiency but significantly reduced bodyweight gain and feed intake compared to controls. Canola meal also negatively affected the yield of carcass, tenders and legs. In addition, including DDGS or canola meal led to a reduction in breast-meat yield, although the difference was not statistically significant compared to controls. There was no interaction between DDGS and canola meal on performance or on the carcass characteristics measured, they said. Back to North American Edition (#4) |
