Abstract
Reviewing utilization of forage fiber by ruminants is a challenging, although extensive task. Probiotics are used widely in ruminant production. Males indicated that microbial cultures have been used primarily for either food preservation, as an aid to restoring gut function, or an agent to enhance feed utilization by ruminants. In the USA, beef cow and calf production systems vary regionally. In the Northeast, cool-season perennials are the forage base. Feedlot growing programs based on harvested roughages provide possible growing program for beef cattle; however, roughage and yardage costs place systems at an economic disadvantage. Breeds with large mature size and high genetic potential for productivity also tend to have slightly greater maintenance needs per unit of body weight. In developing countries, production economics may be less important, and application of existing technology may be the greatest limitation to increased forage use. Labor requirements for pasture-based production systems can limit forage use.
