“…The SCM yield followed the trends of DMI. These observations are in agreement with other reports when diets of similar CP are compared (Grieve et al 1980;Holter et al 1974; Lessard and Fisher 1980;Lahr et al 1983). The SCM produced per unit of DMI and energy output in milk per unit of digest-'ible energy consumed were similar across treatrnents and close to the ratio of SCM/DMI reported by Grieve et al (1980) for cows in 3rd lactation fed a corn silage diet.…”

Atwel, A. S. a,ur ERFLE, J. D. 1988. Comparison of wilted-alfalfa silage and alfalfa hay preserved with propionic acid in corn-silage-based diets for milking cows. Can. J. Anim. Thirty cows (9 uniparous and 2l multiparous) were fed three diets during weeks [5][6][7][8][9][10][11][12][13][14][15][16] of lactation. The dietary ingredients were adjusted weekly to reflect their oven dry matter (DM). production for this preliminary period was used as a covariate to compare the effects of dietary treatments. The number of lactations. the milk oroduced during weeks 6-9 of the previous lactation or during the preliminary period for uniparous cows were used to stratiry the cows into 10 groups of three cows each. One cow from each group was then assigned at random to one of the three experimental diets. A 2-wk interval (weeks 5-6 of lactation) was used as the adjustment period; then milk production and feed intake were recorded for a l0-wk (weeks 7-16 of lactation) experimental period. The SCM data were also anall zed by co',ariance analysis using the individual cow data from preliminary period (weeks 3-4 of lactation) as a covariate (Erfle et al. 1983) In this text, statements of differences or significant differences refer to P < 0.05 unless otherwise stated.
