Resumo: | The objective of this study was to evaluate intake, microbial protein synthesis, and nitrogen balance in lambs fed diets containing 0.00, 12.50, and 25.00% mulberry hay substituting the concentrate. Twentyfour Ile de France lambs at approximately 60 days of age, with a body weight of 15.48 ± 0.07 kg, were confined in individual stalls and slaughtered upon reaching 32 kg body weight. Only the intakes of ether extract and metabolizable energy decreased linearly (P<0.05) as the participation of mulberry hay in the concentrate was increased. Nitrogen in the feces, expressed in g day–1 and g kg0.75 day–1, increased linearly (P<0.05), whereas excretions (mmol day–1) of allantoin, total purines, and absorbed microbial purines, microbial production (g day–1) expressed in microbial nitrogen and microbial crude protein, and microbial efficiency expressed in g MN kg–1 RDOM–1 and g MP kg–1 of TDN decreased linearly as the level of hay in the diet was increased. Mulberry hay substituting the concentrate in diets for feedlot lambs reduces the microbial protein synthesis. |

Foram utilizados vinte e quatro cordeiros Ile de France, com aproximadamente 60 dias de idade e 15,48 ± 0,07 kg de peso corporal, confinados em baias individuais e abatidos ao atingirem 32 kg de peso corporal. Apenas a ingestão de extrato etéreo e energia metabolizável apresentaram redução linear (P<0,05) com a inclusão do feno de amoreira no concentrado. Houve aumento linear (P<0,05) do nitrogênio nas fezes expresso em g dia-1 e g kg0,75 dia-1, redução linear (P<0,05) das excreções (mmol dia-1) de alantoína, purinas totais e purinas microbianas absorvidas, produção microbiana (g dia-1) expressa em nitrogênio microbiano e proteína bruta microbiana, e eficiência microbiana expressa em g Nm kg-1 de MODR-1 e g Pm kg-1 de NDT à medida que aumentou feno de amoreira na ração. O feno de amoreira em substituição ao concentrado na ração de cordeiros confinados reduz a síntese de proteína microbiana.UEL2015-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científicaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1851710.5433/1679-0359.2015v36n6Supl2p4413Semina: Ciências Agrárias; Vol. 36 No. 6Supl2 (2015); 4413-4422Semina: Ciências Agrárias; v. 36 n. 6Supl2 (2015); 4413-44221679-03591676-546Xreponame:Semina.
