Silage and milk production a comparison between concentrates containing different amounts of protected protein as supplements for silage of high digestibility



Silage and milk production a comparison between concentrates containing different amounts of protected protein as supplements for silage of high digestibility



Grass and Forage Science 39(1): 93-100



Grass silage made in late May from S24 perennial ryegrass was offered ad lib to 8 Ayshire cows in a 16-wk feeding experiment. The silage had a DM [dry matter] concentration of 244 g kg-1, contained 163 g crude protein (kg DM)-1 with a ruminal degradability of 0.77 and had an in vitro DOMD [digestive organic matter in the DM] concentration of 678 g kg-1. Four concentrates each containing 167 g soybean meal kg-1 were consumed at a mean daily rate of 6.43 kg DM/cow. The soybean meal was either untreated, or protected by formalin and mixed in the following proportions, 100:0; 66:34; 34:66; and 0:100, respectively, in the 4 concentrates. The daily intakes of silage DM were not significantly different on the 4 treatments and averaged 9.0 kg DM per cow, giving a mean total daily DM intake of 32.4 g kg-1 live weight. The milk yields were not significantly different on the 4 treatments and averaged 23.9 kg d[day]-1. The treatments had small and non-significant effects on milk composition and live weight. With a high-digestibility, well-preserved grass silage of satisfactory protein content the inclusion of protected protein in the supplementary concentrate had no beneficial effects on milk production.
