Energy values of the soybean meal for laying hens in function of the levels of inclusion and of crude protein in the reference diet
Abstract
This study had the objective to
evaluate the values of apparent metabolizable
energy (AME) and nitrogen corrected apparent
metabolizable (AMEn), apparent metabolizability
coefficient (AMC) and nitrogen corrected apparent
metabolizability coefficient (AMCn) of soybean
meal, determined with laying hens. The assay was
constituted of a food test (soybean meal) and two
reference diets. The soybean meal replaced a total
of 14% and 19% of crude protein (CP) reference
diet at the amount 7,5% of and 15%. To determin the
values of AME and AMEn, has been used the total
excreta colletion method, where 72 laying isabrown
hens, were shared experimental random blocks
design in a factorial outline 2x2 (substitution level
of soybean meal X CP level of the reference diet).
There was significant interaction (P<0,05) between
the substitution levels of soybean meal and the CP
levels of the reference diet. Through the results
gotten in this study, it can be inferred that the values
for EMA, EMAn, CMA and CMAn are influenced by
the crude protein levels in the ration reference (14
and 19%), and also for the level of substitution (7,5
and 15%) of the soybeam meal in the ration.
