Resumo: Fed intake and milk production of Holstein-Zebu crossbred cows, grazing Napier grass (Pennisetum purpureum) (NAP), Brachiaria decumbens (BRA) and Guinea grass (Pannicum maximum) (COL) and supplemented with four kg of concentrate, were evaluated in a double Latin square (3x3). Fecal production and feed intake were calculated using Cr2O3 and in vitro digestibility. Dry mater intake (DMI) was similar among forages (18kg/cow) which represented 2.72%; 2.84% and 2.96% of the live weight for NAP, BRACH and COL respectively. The intake per unit of metabolic size (g DM/kg0.75) was 130 for NAP, 135 for BRACH and 145 for COL. The intake of BRACH resulted in lower milk production (14,4kg) than NAP (15,5kg) and COL (16,1Kg). Grasses did not affected the milk composition which showed 4,03% of fat, 2,46% of protein and 12,42% of total solids. It was concluded that NAP, BRACH and COL are good alternatives for milk production in grazing systems. KEY WORDS: Brachiaria decumbens, Guinea grass, Panicum maximum, Napier, Pennisetum purpureum.

KEY WORDS: Brachiaria decumbens, Guinea grass, Panicum maximum, Napier, Pennisetum purpureum.Realizou-se a avaliação do consumo de alimentos e da produção de leite de vacas mestiças pastejando piquetes de capim Napier (Pennisetum purpureum) (NAP), Brachiaria decumbens (BRA) e Colonião (Pannicum maximum) (COL) e suplementadas com quatro kg de concentrado em um esquema de quadrado latino (3x3) duplo. Calcularam-se a produção fecal e o consumo de alimentos com o auxílio do Cr2O3 e da digestibilidade in vitro. O consumo diário de MS foi semelhante entre as forragens (18kg/vaca), as quais representaram 2,72%; 2,84% e 2,96% do p.v. para o NAP, BRACH e COL, respectivamente. O consumo por unidade de tamanho metabólico (g MS/kg0,75) foi de 130 para o NAP, 135 para a BRACH e 145 para o COL. A ingestão de BRACH resultou em menor produção de leite (14,4Kg) em comparação ao NAP (15,5kg) e COL (16,1kg). Verificou-se que as espécies forrageiras não influíram na composição do leite das vacas, o qual apresentou 4,03% de gordura, 2,46% de proteína e 12,42% de extrato seco total. Concluiu-se que os capins NAP, BRACH e COL apresentam-se como boas alternativas para a produção de leite a pasto.PALAVRAS-CHAVES: Brachiaria decumbens, colonião, Pannicum maximum, Napier, Pennisetum purpureumUniversidade Federal de Goiás2008-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisaapplication/pdfhttps://revistas.ufg.br/vet/article/view/79410.5216/cab.v9i3.794Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 9 No. 3 (2008); 578-589Ciência Animal Brasileira / Brazilian Animal Science; v. 9 n. 3 (2008); 578-5891809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/794/4124Benedetti, EdmundoRodríguez, Norberto MarioCampos, Warley EfremBorges, Ana Luiza Costa CruzSaliba, Eloísa Simõesinfo:eu-repo/semantics/openAccess2008-10-15T19:36:43Zoai:ojs.revistas.ufg.br:article/794Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:54:44.539487Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
