E-mail: vciganda@inia.org.uy  aThe objective of this study was to determine to what extent the inclusion of medium and high tannin content legumes in NG affects the excretion of N in feces and urine of beef heifers compared to NG without legumes. The experiment was carried out at the Research and Experimental Center Dr. A. Gallinal (CIEDAG-SUL), Uruguay, from 20/10/21 to 22/11/21.  aNative grasslands  aNitrogen (N)1 aSIMÓN, C.1 aSANTANDER, D.1 aMARIOTTA, J.1 aMULETA, E.1 aMARCHELLI, J.P.1 aLATTANZI, F.1 aNÓBREGA, G.N.1 aRODRIGUES, R.A.R.1 aCIGANDA, V.
