Nutritive Value of Whole Crop Silage Made From Seven Cereal Cultivars

Voluntary intake and diet selection by dairy heifers fed ensiled whole-crop barley and oats harvested at different stages of maturity

“…However, there were no significant differences in intake among oat, sixrowed barley and two-rowed barley silages harvested at the early milk stage, despite the higher content of fermentation products, lower DM content and lower in vitro ROMD in the oat than in the barley silages. In accordance with our results, Christensen et al (1977) found the DMI to be lower for barley than for oat silage when the crops were harvested at the middough stage and attributed this to the lower palatability of barley due to its sharp awns. In Sweden no awnless cultivars of barley are commercially available, so both the six-rowed and two-rowed cultivar used in the present study had barbed awns which could have reduced the DMI of these silages.…”

“…Oats generally have lower DM digestibility and NDF digestibility than barley, similarly to the ROMD in the present study (Christensen et al, 1977;McCartney and Vaage, 1994;Nadeau, 2007). However, there were no significant differences in intake among oat, sixrowed barley and two-rowed barley silages harvested at the early milk stage, despite the higher content of fermentation products, lower DM content and lower in vitro ROMD in the oat than in the barley silages.…”

“…This difference in maturity-related change between WCCS and grass silage make it difficult to predict the DMI of WCCS from models based on grass silage data. Moreover, Christensen et al (1977) showed that awned cereal species, e.g. barley, were less palatable than species without awns, e.g.…”

Comparative yield and feeding value of barley, oat and triticale silages

“…In contrast to yield, the nutritional value of oat is generally lower than for other cereals. Crude protein (CP) concentrations tend to be higher in wheat, triticale and barley than in oat silage (Tingle and Dawley 1974;Christensen et al l9'/l; Berkenkamp and Meeres 1988). In vitro dry matter (DM) and organic matter (OM) digestibilities appear to be greatest for barley and lowest, again, for oat silage (Fisher and Fowler 1975;Nass et al 1975;Cherney and Marten 1982).…”

The Effect of Type of Silo and Formic Acid Preservation on the Nutritive Value of Barley, Wheat and Oat Silages for Growing Hereford Steers

“…The experimental reliability of the galvanized culvert silos used by Christensen et al (1977a, (Harvey 1960 (Li 1964 Voluntary intake (g/Wx*'tt) of dry matter was lowest (P < 0.05) for the formicacid-treated Wascana, followed by the untreated Wascana wheat silage ( The effects of formic acid on preserving cereal silages in the 307o-35%o dry matter range were similar to those reported for the lower dry matter grass and legume silages (Castle and Watson 1973;Waldo et al 1969) in that it produced lower maximum temperatures, lower pH and higher nutrient recoveries. Cereal silages treated with formic acid did not have nutrient digestibilities which differed from untreated silages.…”
