Resumo: | Given the significant share of food costs of poultry production, it is necessary to use
strategies and techniques to maximize the utilization and biological value of the
components of the diets, keeping constant or improving animal performance. In this
context, seeking partial substitution of corn and the best use of the constituents of the
diet, the present study aimed to evaluate the effects of inclusion of cashew pomace
dehydrated (BCD) and enzyme complex (EC) in the diet on performance and quality
eggs of Japanese quails. A total of 200 Japanese quail at 87 days of age, in 25 cages in a
completely randomized design in a factorial 2 x 2 + 1 (two levels of cashew bagasse x
two levels of enzymes) + control diet without cashew bagasse totaling five treatments
with five replicates of eight birds each repetition. The experiment lasted 84 days,
divided into four periods of 21 days. The treatments consisted of T1-Ration Control,
T2-ration with 7.5% without EC BCD, T3-ration with 7.5% BCD with CE, T4-Ration
with 15% BCD without EC and T5-Feed with 15% of BCD with EC. The enzyme
complex (EC) is used fermentation product of Aspergillus niger, and cashew bagasse
was obtained from the juice industry, passed through drying and crushing process for
producing the bran. The performance and egg quality of quails, and performance
variables: feed intake (FI), feed conversion ratio per dozen eggs (CAKDZ) and egg
mass (CAMO), egg production (OP% bird / day), average egg weight (PMO) and egg
mass (MO), and variables were egg quality, specific gravity (SG), Haugh unit (HU),
yolk index, and the relationships between components eggs (%albumen,% yolk and
%shell). Data were analyzed with the Statistical SAEG (2007). The 7.5 and 15% of
cashew bagasse, independent of the enzyme complex decreased feed intake and
improved the average egg weight. The two levels with the addition of EC showed
significant differences for feed conversion by egg mass. The 7.5 with the addition of
enzyme complex obtained the lowest average feed conversion per dozen eggs. The
inclusion of up to 15% of cashew bagasse dehydrated with or without addition of enzyme complex in the diet of Japanese quails not interfere in the internal and external
quality of eggs. The 7.5 and 15% BCD without added enzyme complex gave better
means for specific gravity. Under conditions in which the experiment was conducted, it
can be stated that the inclusion of up to 15% of cashew bagasse dehydrated with added
enzyme complex feeding quail is economically viable, with the level of 7.5% with the
addition of complex enzyme presented the best economic indices |
