Abstract:
... Context Dry matter intake (DMI) is the variable that most affects beef cattle performance in feedlot conditions. Accurate prediction of DMI is essential because it is the basis for calculating nutritional requirements for maintenance and production. Aims A meta-analysis was conducted to develop DMI prediction models for feedlot beef cattle under tropical conditions, and to compare the models ...

Abstract:
... Silage is the main source of acetic acid in ruminant diets. In most silages, acetic acid is the fermentation product with the second highest concentration, after lactic acid. As it inhibits yeasts and therefore improves aerobic stability of silages, moderate concentrations of up to 30 g/kg dry matter (DM) are often recommended. However, acetic acid may impair the DM intake (DMI) by ruminants, most ...

Abstract:
... Dairy cow efficiency is increasingly important for future breeding decisions. The efficiency is determined mostly by dry matter intake (DMI). Reducing DMI seems to increase efficiency if milk yield remains the same, but resulting negative energy balance (EB) may cause health problems, especially in early lactation. Objectives of this study were to examine relationships between DMI and liability ...
