Grazing Behavior of Ruminants and Daily Performance from Warm-Season Grasses

摘要: An estimate of the animal-production potential pastures can be assessed by knowing daily dry matter (DM) intake grazing animal and digestibility DM consumed. The objective this paper is to examine relationships between pasture canopy characteristics, ingestive behavior, response from warm-season pastures. Of consumed, former most variable difficult determine. One approach estimating has been use components behavior determine a short-term rate (g min -1 ), which scaled using time (min d ) give 24-h (kg ). This used experimentally with some success, but not found application in production settings. While aspects including mastication, are common all ruminants, literature indicates that differences occur among ruminant species animals ingest different differently. results plant-animal interactions. Frequently these dynamics clearly addressed for cool-season renews, adds undue confusion general area. Ingestive discussed relative animal- pasture-generated bounds operate within paddocks greatly alter estimates. Also presented diet particle size, associated steer gains.
