Níveis de suplementação de novilhos mestiços mantidos a pasto

Abstract: RESUMOObjetivou-se com este trabalho avaliar níveis crescentes de concentrado na engorda de novilhos mestiços, suplementados a pasto no período seco do ano. O experimento foi conduzido no Setor de Bovinocultura do Departamento de Zootecnia da Universidade Federal de Lavras UFLA, entre os meses de Abril a Junho de 2002. Foram utilizados 24 bovinos mestiços (Holandês x Zebu), machos, castrados e com peso vivo médio de 281 kg, no início do experimento. Durante o período experimental os animais foram alojados em u… Show more

“…This statement explains the low weight gain of animals that received mineral supplementation only and the higher performance of those which consumed concentrate supplements. Positive responses to concentrate supplementation in weight gain by grazing cattle during the rainy-dry transition period were also observed by Leão et al (2005) and Sales et al (2008).…”

“…Para garantir ganhos individuais compatíveis com menores ofertas de forragem pode-se aumentar o nível de suplementação, sendo que essa decisão deve visar a melhor rentabilidade. LEÃO et al (2005) avaliando níveis crescentes de suplemento (0%, 0,2%, 0,4%, e 0,6% do PC) em novilhos mestiços Holândes x Zebu, mantidos em pastagem de Brachiaria brizantha, verificaram que quanto maior o nível de suplemento, maior o GMD (dentro do intervalo de 0 a 0,6% do PC). Nesse sentido, os autores concluíram que o fornecimento de suplemento de 0,6% do PC resultou em melhor resposta com GMD de 0,516 kg/ animal/ dia.…”

“…One aspect that deserves consideration concerns the total availability of DM, which, even at the end of the experiment reached 1,731.57 kg/ha, reflecting the rainfall rates, the intense sunlight and the high temperatures during the rainy season, and these together maximized the growth of forage plants, increasing their availability and quality (Leão et al, 2005). Thus, Graham et al (1993), in their research with sheep, affirm that when the availability of DM is more than three times greater than the amount needed by the animals and the digestibility of this dry matter is greater than 55%, grazing can be effective and the animals can achieve high levels of performance.…”
