Avaliação da substituição do milho pelo resíduo seco da extração da fécula de mandioca sobre o desempenho de novilhas mestiças em confinamento

Abstract: RESUMO -O objetivo neste trabalho foi avaliar o efeito da substituição total do milho pelo resíduo seco de mandioca sobre o desempenho de novilhas mestiças terminadas em confinamento. Foram utilizadas 30 novilhas mestiças com idade aproximada de 21 meses e peso vivo médio de 325 kg, agrupadas em dois lotes experimentais e alojadas em duas baias. Os dois lotes foram submetidos a um período pré-experimental de 49 dias, no qual receberam silagem de sorgo, à vontade, e concentrado à base de farelo de soja, milho e… Show more

“…A similar result was observed for medium heifers in comparison to lighter heifers. The observed weights for the three heifer categories were according to the requirements of the Brazilian market (Abrahão et al, 2006;Macedo et al, 2007;Marques et al, 2006a;Prado et al, 2000b). In general, crossbred heifers (Bos taurus x B. indicus) finished in the feedlot within a similar management regime showed a final body weight of between 320 and 400 kg (Kazama et al, 2008;Marques et al, 2000).…”

“…In their evaluation of partial replacement (50%) of corn by dry starch mass for Nellore calves and crossbreeds with Angus cattle, Marques et al (2006) did not report any difference in the intake of dry matter (9.0 kg) and food conversion (8.4 kg kg -1 gain). However, when they evaluated total replacement of corn by dry starch mass for crossbreed calves, (Abrahão et al, 2006a) reported that the byproduct decreased the ingestion of dry matter and feed conversion.

“…The breeding of dairy cows in feedlot requires diets with high energy density that permits the genetic capacity of production and the adequate composition of milk. According to Abrahão et al (2006a), the use of a high proportion of grains in these systems implies high costs which may cause liability during periods in which the price of grain is high.…”

“…Abrahão et al (2006), em pesquisa com novilhas mestiças com 21 meses de idade, alimentadas com concentrado à base de milho ou resíduo seco de fecularia, encontraram ganhos de peso médio diário de 1,02 kg/dia. Valor próximo foi encontrado neste estudo para os animais ¾ CN, ½ CN, ⅝ Simental × ⅜ Nelore e Three-cross, de 1,04; 0,95; 0,94 e 1,07 kg/dia, respectivamente.…”
