The effect of various additives on nutritive value of ryegrass straw silage

Creator:

Shultz, Thomas Anthony

Abstract:

Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...

In vitro and in vivo evaluations of chemically treated ryegrass straw

Creator:

Anderson, Daniel Craig

Abstract:

Seven in vitro trials were conducted to compare the effects of soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH), potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM) was the criterion used to measure treatment response. A 3 x 3...

The effects of aerobic and anaerobic fermentation on the nutritive value of ryegrass straw

Creator:

Jones, Steven Ryan

Abstract:

A series of in vitro laboratory trials and in vivo sheep digestion trials were used to evaluate aerobically or anaerobically fermented perennial ryegrass straw. The laboratory trials consisted of a silage study, where mini-silos were used in a 9 X 2 factorial design with nine levels of whey (0 to...
