ABSTRACT

In order to evaluate the nutritional quality of four Mexican soybean meals from the states of Guanajuato, Veracruz, Hidalgo and Nuevo Leon in Mexico, two experiments were conducted. Previously to the experiments, meals were analyzed, resulting to be within standards for crude protein, amino acid profile, urease activity and protein solubility. Data obtained in experiment one, in which soybean meals were used as a protein source in sorghum + soybean meal diets for broilers during 42 days, indicated that for weight gain (2 057, 2 004, 2 078 and 1 978 g), feed consumption (3 860, 3 763, 3 666 and 3 498 g) and feed conversion (1.87, 1.88, 1.76 and 1.77) there were no differences (P ‹ 0.05) among the four meals. In experiment two, True Metabolizable Energy (TME) was determined in Leghorn roosters by using a precise feeding method with the four soybean meals. Results were 2 450, 2 384, 2 430 and 2 290 kcal/kg with a mean of 2 388 kcal/kg, without differences (P ‹ 0.05) among meals, and showed no statistical difference of the nutritional value among the four sources of soybean meal used regarding broiler performance and determination of the TME.
