Chemical and nutritional characteristics of different types of DDGS for ruminants
Journal Title: Journal of Animal and Feed Sciences - Year 2012, Vol 21, Issue 3
Abstract
In this study, different types of cereal grains (maize, wheat, triticale), and their respective distillers dried grains with solubles (DDGS: DDGSM, DDGSW, DDGST) were used. Their effects on parameters expressing nutritional value for ruminants were assessed. The chemical composition of the DDGS was significantly differed (P<0.01), similarly as that of the cereal grains. The DDGS from maize was the highest in fat (103.5 g. kg-1 DM) but the lowest in crude protein (CP) (291.9 g. kg-1 DM) and ADF (159.9 g. kg-1 DM). All DDGS types had similar energy values (ME approx. 12.5 MJ. kg-1 DM, NEL approx. 7.5 MJ. kg-1 DM and NEV approx. 7.6 MJ. kg-1 DM). The DDGS were three times higher in PDIN values than the original grains (P<0.01). DDGSM had lower in situ effective CP degradability (46.5%) than DDGSW (58.5%) and DDGST (76.8%), but the highest and most stable intestinal digestibility (ID) of rumen undegraded CP (94.3%). The most variable intestinal digestibility was found in DDGSW samples (79.6%-92.2%). The acid detergent insoluble CP (ADICP) content (% from total CP) was significantly higher in wheat and triticale DDGS than in the original grains. There were significant plant effects on fat, ME, NEV, ADICP (P<0.01), ADF, and NADIP (P<0.05). We can conclude that all types of DDGS are a good source of CP and energy for ruminants. KEY WORDS: maize, wheat, triticale, DDGS, nutritional value, effective CP degradability, intestinal digestibility
