Desempenho forrageiro e animal em azevém pastejado por novilhas de corte em sistemas integrados de produção agropecuária com lavoura de arroz em terras baixas

Abstract

This study evaluated the forage performance of ryegrass and the animal performance of beef heifers in integrated agricultural production systems in lowlands. The experiment was conducted in a randomized block design with four treatments: rice monoculture, rice-ryegrass succession, rice-ryegrass-soybean-ryegrass succession, and ryegrass-Sudan grass succession. Dry matter productivity, forage nutritional value, animal weight gain, and grazing behavior were analyzed. Results showed that ryegrass is a promising alternative for producing quality forage, contributing to significant weight gains in beef heifers in integrated systems.
