Resumo: The work objectived to evaluate the plasmatic and urine urea concentrations, the balance of nitrogen compounds, and to estimate the protein requirements for maintenance. It was used the equations recommended by the American and British systems, in four bovine and four bubaline steers, with initial average weight of 461,19±7,59 and 455.44±7,85 kg for the bovines and bubalines, respectively, distributed in two 4 x 4 Latin squares. The treatments consisted of different levels of concentrate (0.0; 24.0; 48.0; and 72.0%) composed by grinded corn, soybean meal, mineral salt, and Tifton-grass hay. Each period lasted 21 days, being 14 of adaptation and seven for collection. Samples of feces and urine (spot) were taken to estimate the production of fecal dry matter and urine volume. It was observed interactions between the species for N intake (NC), N-urine (UN) g/kg0,75 and urinary urea (UU); no interactions occurred for fecal-N (NF), absorbed-N (NABS), UN (g/d), balance of N (BN) and plasmatic urea (UP). Regardless of the difference observed between the species, the response variables increased linearly as the concentrate level increased. The increase of the concentrate level provided positive BN. The estimative of the metabolizable protein maintenance requirements of bovines and bubalines differs between the American and British systems.

Os tratamentos consistiram em diferentes níveis de concentrado (0,0; 24,0; 48,0; 72,0%) à base de milho moído, farelo de soja e sal mineral, e feno de capim-tifton. Cada período durou 21 dias, sendo 14 de adaptação e sete para coleta. Foram coletadas amostras de fezes e urina (spot) para estimativa da produção de matéria seca fecal e volume urinário. Houve interação entre as espécies para nitrogênio (N) consumido (NC), urinário (NU)g/kg0,75 e uréia urinária (UU); não ocorrendo para N fecal (NF), N absorvido (NABS), NU (g/d), balanço de N (BN) e uréia plasmática (UP). Independente do efeito observado entre as espécies, as variáveis aumentaram linearmente em função dos tratamentos. O aumento dos níveis de concentrado proporciona BN positivo. Os requerimentos de proteína metabolizável para mantença de bovinos e bubalinos, quando estimados por meio dos sistemas americano e britânico, são diferentes.Submitted by (edna.saturno@ufrpe.br) on 2017-04-24T16:04:54Z No. of bitstreams: 1 Kedes Paulo Pereira.pdf: 146728 bytes, checksum: c8731b0bfca572bc124ee13380b4adf6 (MD5)Made available in DSpace on 2017-04-24T16:04:54Z (GMT).
