Novel mixtures of Italian ryegrass and winter cereals: influence of ensiling on nutritional composition, fermentation characteristics, microbial counts and ruminal degradability

The study was conducted with the objective of evaluating nutrient content, fermentation characteristics, microbial counts, and ruminal degradability two mixtures Italian ryegrass (Lolium multiflorum Lam.) winter cereal silages. Two (mixture A: ryegrass, triticale, oats, wheat barley; mixture B: oats) were wilted ensiled in laboratory‐scale silos without additives. At end 90 d B silage had higher (p < .05) dry matter (DM), ether extract (EE), crude fibre (CF), neutral detergent (NDF) acid (ADF) contents than A silage. pH value Mixture lactate, acetate ethanol B. However, NH3-N (day 14) mould yeast count (Log10 CFU g−1) for at opening day 7. situ incubation revealed that potentially degradable fraction (b) DM, CP NDF 39.41%, 43.59%, 80.23% A) 39.16%, 32.39%, 94.35% B). effective protein (EPD) 0.08 rumen outflow rates 67.26% 67.19% These results suggest proper stage harvesting, fermented well. This kind can be additives future. high implies this could included successfully high-yielding dairy cattle diets.HighlightsItalian are well preserved it saves cost farmers.The have degradability, which improve intake, milk production increase net return farm.The forage double-cropped corn making, both environmental economic benefits if yields enough to cover expenses.
