Resumo: | The present work to evaluate the effect of supplementation of urea release slow partial substitution of urea present in the common protein salt of heifers grazin Tifton-85 during the winter. The study was coducted in the period from May to September 2010. In an area of ??11.6 hectares of grazing Tifton-85 (Cynodon dactylon), divided into four paddocks of 2.9 acres, 36 heifers were kept testers (½ Red Angus ½ Nellore), treated as follows: Only mineralized salt (SM) protein salt with urea (SP); protein salt with 25% substitution of urea by slow degradation of urea (SPLD25) and protein salt with 50% substitution of urea by slow degradation of urea (SPLD50). There was no effect of different sources of supplementation on animal performance (P>0.05). However, differences were observed between the experimental periods, in consequence of the variation in chemical and structural composition of the forage. |

O presente trabalho objetivou avaliar o efeito da suplementação com uréia de liberação lenta em substituição parcial da uréia comum, presente no sal proteinado de novilhas pastejando em capim Tifton-85 no período do inverno. O trabalho foi realizado no período de maio a setembro de 2010, em uma área de 11,6 hectares de pastagem de Tifton-85 (Cynodon dactylon), dividida em quatro piquetes de 2,9 hectares. Foram mantidas 36 novilhas testers (½ Red Angus ½ Nelore), submetidas aos seguintes tratamentos: apenas sal mineralizado (SM); sal proteinado com uréia (SP); sal proteinado com 25% de substituição da uréia por uréia de lenta degradação (SPLD25); e sal proteinado com 50% de substituição da uréia por uréia de lenta degradação (SPLD50). Não houve efeito das diferentes fontes de suplementação sobre o desempenho dos animais (P > 0,05), sendo recomendado a utilização de sal mineralizado que apresenta menor custo.UEL2013-03-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1104510.5433/1679-0359.2013v34n1p409Semina: Ciências Agrárias; Vol. 34 No. 1 (2013); 409-418Semina: Ciências Agrárias; v. 34 n. 1 (2013); 409-4181679-03591676-546Xreponame:Semina.
