Resumo
In this experiment, the inclusion of viscera and bone meal (FVO) and
feather and blood meal (FPS) according to its processing grade was evaluated in
broiler pre-starter and starter rations. The experiments were conducted in the
poultry experimental facilities of the Veterinary College of the Federal University of
Goiás (EV/UFG), located in Goiânia, Brazil. A total of four experiments were
carried out to evaluate performance, digestibility and intestinal biometry of broilers
fed diets containing viscera and bone meal (FVO) with different moisture levels in
processing and feather and blood meal (FPS) with different pressing levels in
processing in pre-starter (one to seven days of age) and starter (eight to 21 days
of age). In the first experiment, 9% inclusion of FVO with different moisture levels
at processing (4, 5 and 6%) in pre-starter rations. In the second experiment, the
same moisture levels of FVO were analyzed for starter rations. In the third
experiment, 9% inclusion of FPS with different hydrolysis pressing at processing
(2,0, 2,5 e 3,0 kg/cm2) in pre-starter ration was tested. In the experiment 4, the
same hydrolysis pressing levels were tested for FPS but now at starter rations.
The experiment was conducted in a randomized block design, and the criteria to
the blocks determination was the battery-cage, with four treatments and five
replications of 12 birds each, in a total of 20 experimental units. The statistical
analysis was done using UFV/SAEG (2000) and means compared as Tukey test
(%5). Variables tested were: live weight, weight gain, feed intake, feed-to-gain
ratio, dry matter, nitrogen and ether extract digestibility, dry matter, nitrogen and
ether extract retention and biometric indexes of digestive organs. The results
indicated that 9% of FVO or FPS didn t affect the performance results. To prestarter
phases, the best results were obtained with diets processed with FVO with
5% moisture and FPS with 2,5 kg/cm2 of hydrolysis processing. For starter rations,
FVO or FPS didn t affect broiler performance. The poultry by-products processed
for animal feeding can be used without performance lost but is important to know
the nutritional processing of these ingredients.
