Abstract

BEEF production in Venezuela is essentially carried on under grazing conditions. The use of concentrate supplements to reduce body weight losses during the dry season and to insure more accelerated gains during the rainy season is practically unknown.

With the increased demand for meat and the establishment of price differentials for an improved product, ample justification exists to initiate research on the practice of supplementation for animals under grazing conditions and the regulation of concentrate consumption using high salt levels.

The incorporation of salt in the supplement to regulate intake has been demonstrated by some authors to be practical for beef cattle (Cardon et al., 1951; Riggs, Colby and Sells, 1953; Savage and Mcllvan, 1954; Meyer et al., 1955; Kroger and Carroll, 1964) and sheep (Weir and Miller, 1953; Weir and Torrell, 1953), while others have observed limitations to this practice (Hentges et al., 1967; Wagnon, 1965).

The objectives of this experiment were to evaluate the effect of self-feeding a 30% salt-supplement to beef cattle grazing average quality tropical pasture on animal performance, some rumen processes and hematic values, apparent digestibility and carcass characteristics.
