Resumo: | In a trial conducted on a distrofic Red-Yellow Latossol, at EMBRAPA-CPPSE, São Carlos, located at 22°01'S and 47'53'W, altitude of 856 m and with a mean annual rainfall of 1502 mm, the bromatological composition of leaves, stems smaller than 6 mm diameter and pods of leucena genotypes was determined. The genotypes evaluated were: L.leucocephala cv. Texas 1074 (T1), L.leucocephala 29 A9 (T2), L.leucocephala 11 x L.dlversifolia 25 (T3), L.leucocephala 11 x L.diverstfolia 26 (T4), L.leucocephala 24-19/2-39 x L.diversifolia 26 (T5) and L.leucocephala cv. Cunningham (control). It was found that: - The evaluated genotypes did not show differences among themselves for bromatological determinations on leaves and fine stems; - T3 genotype had the greatest content of crude protein (28.06%), phosphorus (0.29%), the greatest PB/FDN relation, and the smaller FDN content of pods; - The genotypes presented the following average percentual contents of the bromatological composition of leaves, pods and stems smaller than 6 mm diameter, respectively: Crude Protein (18.57; 21.68; 6.41); Neutral detergent fiber (29.09; 41.58; 71.01); Phosphorus (0.12; 0.22; 0.06); Calcium (1.39; 0.36; 0.49); Magnesium (0.51; 0.28; 0.24); Tannin (1.32; 1.15; 0.28) and "in vitro" digestibility (58J9; 61.22; 33.61); - Protein and phosphorus contents presented the following decreasing order in plant parts: pods >; leaves >; stems smaller than 6 mm diameter; calcium contents: leaves >; stems smaller than 6 mm diameter >; pods; and the magnesium: leaves >; pods >; stems smaller than 6 mm diameter. |

The genotypes evaluated were: L.leucocephala cv.

Em experimento conduzido em Latossolo Vermelho-Amarelo distrófico, em área da EMBRAPA - CPPSE em São Carlos, situada a 22°01'S e 47°53'W, com altitude de 856 m e média de precipitação anual de 1502 mm, procedeu-se a determinação da composição bromatológicade folhas, hastes com diâmetro menor que 6 mm e vagens, de genótipos de leucena. Os genótipos avaliados, foram: L.leucocephala cv. Texas 1074 (TI), L.leucocephala 29 A9 (T2), L.leucocephala 11 x L.dlversifolia 25 (T3), L.leucocephala 11 x L.diversifolia 26 (T4), L.leucocephala 24-19/2-39 x L.diverstfolia 26 (T5) e L.leucocephala c v. Cunningham (testemunha). Verificou-se que: os genótipos avahados não apresentaram diferenças nas determinações bromatológicas, realizadas nas folhas e talos finos; o genótipo T3 registrou o maior teor de proteína bruta (28,06%), de fósforo (0,29%) e a maior relação PB/FDN e o menor teor de FDN para vagens; os genótipos apresentaram os seguintes teores médios, em porcentagem, para a composição bromatológicadas folhas, vagens e talos finos, respectivamente: Proteína bruta (18,57; 21,68; 6,41); Fibra detergente neutro (29,09; 41,58; 71,01); Fósforo (0,12; 0,22; 0,06); Cálcio (1,39; 0,36; 0,49); Magnesio (0,51; 0,28; 0,24); Tanino (1,32; 1,15; 0,28) e Digestibilidade "in vitro" (58,39; 61,22; 33,61); os teores de proteína e fósforo apresentaram a seguinte ordem decrescente nas partes das plantas: vagens >; folhas >; talos finos; os teores de cálcio: folhas >; talos finos >; vagens e de magnésio: folhas >; vagens >; talos finos.
