E xperimental diets were form ulated with 30% of the test ingredient and 70% of a commerci al diet supplemen ted with 1% of chromium oxide as inert marker. AA cont ents in ingredients, diets, leached diets, and feces were de termined by high performance liquid chromatography. Pr eprandial AA losses attributed to leaching were h igher in the blood meal diet (15%) and pork meal diet (10 %). Poultry meal diets 1 and 2 showed mean AA losses of 3% and 5%, respectively, wh ile the reference diet had a mean AA leaching of 6% . The AA that had the highest leaching rates were lysine (21%), methionine (15%), an d histidine (12%). The ADC of dry matter was higher fo r poultry meals 1 (70%) and 2 (73%), followed by pork meal (69%), feather meals (61%) , and blood meal (57%). The digestibility of CP was higher for poultry meals (78–80%), foll owed by pork meal (76%), and blood meal an d feather meals (65–67%). The digestibility of CP in the reference diet (83%) was higher than that obser ved for all the animal by-product meals except the poultry meals. The ADC of the sum of AA adjusted for nutrient leaching fluctuated from 65% for blood meal to 80% for poultr y meals. 2014 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48032071001 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.3 Vol.40 |
