Descrição: dc.descriptionWith the objective of determine the bioavailability of two lysine sources (lysine HCl and lysine sulfate), by a growth trial, 840 one day old male broiler chicks were placed in 56 boxes. Two basal diets were formulated to supply the birds nutritional requirements, one for the starting and the other for the growing period, respectively, deficient only in lysine, which were supplemented 0,08, 0,16 and 0,24% lysine of both lysine sources. Weight gain, feed intake, feed conversion, carcass yield, legs quarter yield, breast yield, breast meat yield and abdominal fat content were evaluated. Multiple linear regression and the slope ratio technique was used to estimate equations. The bioavailabity of lysine sulfate was obtained as a percentage of lysine HCl considered as 100% available. The equations that best estimated the bioavailability of the lysine sulfate (X2) related to lysine HCl (X1) were: Y = 544,72 + 439,62 X1 + 475,84 X2, R2 = 0,90, for weight gain (1 to 21 days of age); Y = 1824,63 + 1469,18 X1 + 1381,33 X2, R2 = 0,85, for weight gain from 01 to 42 days of age;11 Y = 1,9623 - 0,9043X1 -1,0235 X2, R2 = 0,83, for feed conversion (1 to 21 days of age); Y = 0,3766 + 0,5320 X1 + 0,4986 X2, R2 = 0,88, for breast yield (42 days of age) and Y = 0,2565 + 0,4685X1 + 0,4300 X2, R2 = 0,92 for breast meat yield with 42 days of age. The average bioavailability of lysine sulfate was 100,19%, showing that there was no difference (p > 0.05), in the bioavailability of the two lysine sources studied.-
