Effect of nutrient composition of feeds on digestibility of organic matter by cattle: A review1

Abstract: Estimates of nutrient availability, calculated as TDN for 106 different feedstuffs generated from various published equations, were compared with TDN for similar feeds listed in the 1961 text by F. B. Morrison titled Feeds and Feeding. Incomplete analysis of carbohydrate fractions limited accuracy of evaluations. Although published equations may satisfactorily rank feeds in energy value, the absolute values, correlations, and SE of the estimates revealed that most equations were inaccurate. Across all feeds an… Show more

“…This may imply that the magnitude of rumen fermentation, or rather the number of ruminal bacteria was not influenced by the amount of tomato pomace in the ration, which was indeed found. However, the apparent, total gastro-intestinal tract digestibilities of NDF and ADF can be determined by fermentation in the hindgut (Owens et al, 2010). Diet effects on fermentation of NDF and ADF in the rumen could be negated by diet effects on fermentation in the hindgut.…”

“…Data of feed quality which evaluated was the content of dry matter (DM), crude protein (CP), crude fiber (CF), eter extract (EE), material extract without nitrogen (NFE) (AOAC, 2005). Total digestible nutrients (TDN) was calculated according to Owens et al (2010).…”

“…The influence of feed on the efficiency is usually evaluated with nutritional parameters, such as chemical composition, digestibility, (Owens et al, 2010) or feed conversion rate (Comerford et al, 1991). However, evaluation on the animal behavior in responding the feed given is not widely observed (Bingham et al, 2009).…”
