Suplementação de Bovinos em Pastagem de Coastcross (Cynodon dactylon (L.) Pers) no Verão

Abstract 

This trial was carried out in Luiziana, northwest of Paraná, from November 2000 to February 2001. Twenty-four animals with 325 kg of initial body weight and 13 months of age, from two different genetic groups, ½ Red Angus ½ Nellore (20) and ½ Marchigiana ½ Nellore (12) were used. Animal performance was evaluated, under grazing conditions on coastcross (Cynodon dactylon (L.) Pers) and four levels of soybean hulls: 0, 0.2, 0.4, and 0.6% of body weight. Pasture production and quality were also evaluated. The experimental area consisted of four paddocks of Coastcross, with 5.05 ha of total area. After 112 days of experimental period, all treatments showed high gains per animal (above 0.850 kg/day). Key Words: grazing, performance, soybean hulls, steers

RESUMO - O experimento foi realizado no município de Luiziana, noroeste do Estado do Paraná, no período de outubro de 2000 a fevereiro de 2001. Foram utilizados 32 novilhos inteiros, com 13 meses de idade e peso inicial médio de 325 kg, pertencentes a dois grupos genéticos distintos, sendo 20 ½ Red Angus ½ Nelore e 12 ½ Marchigiana ½ Nelore. Avaliou-se o desempenho destes animais, em quatro piquetes de Coastcross (Cynodon dactylon (L.) Pers), perfazendo um total de 5,05 ha e diferentes níveis de suplementação energética (na base de 0; 0,2; 0,4; e 0,6% do peso vivo) com casca de soja. Foram realizadas estimativas da disponibilidade e da qualidade da forragem. Após 112 dias de experimento, observaram-se elevados ganhos de peso para todos os tratamentos (acima de 0,850 kg/dia).
