| ABSTRACT Bovine meat and bone meal (MBM) has been used as a low-cost protein source in corn- and soybean meal-based poultry diets. However, to date, no studies investigating the effect of the dietary inclusion of MBM on the performance of Japanese quails and on egg production costs were found in literature. In this study, 600 Japanese quails in lay were distributed in a completely randomized experimental design consisting of six treatments (replacement levels of soybean meal by MBM:0, 1, 2, 3, 4, and 5%) with five replicates of 20 birds each to investigate if MBM is a viable alternative to maintain or to improve the live and economic performances of these birds. Treatments consisted of a control diet, based on corn and soybean meal, with no inclusion of... |

| This study aimed at evaluating the effect of dietary calcium levels and the replacement of calcium sources with different particle size compositions on the performance and egg quality of brown layers in their second egg production cycle. A randomized block experimental design was applied with 12 treatments in a 3x4 factorial arrangement: three calcium levels (2.6, 3.2, 3.8 %) and four combinations of calcium sources (1- 100% fine limestone (FL), 2- 50% FL + 50% coarse limestone (CL), 3- 50% FL and 50% oyster shell (OS), 4- 50% FL and 25% CL+ 25 %OS), with six replicates of eight birds each. Calcium sources were analyzed for geometric mean diameter (GMD) and in-vitro solubility. The following performance and egg quality parameters were evaluated: egg weight... |
