Item FARINHAS DE RESÍDUOS DE ABATEDOUROS AVÍCOLAS EM DIFERENTES GRAUS DE PROCESSAMENTO EM RAÇÕES PRÉ-INICIAIS E INICIAIS DE FRANGOS DE CORTE(Universidade Federal de Goiás, 2008-08-28) LABOISSIERE, Michele; CAFÉ, Marcos Barcellos; http://lattes.cnpq.br/9860968235125158; LEANDRO, Nadja Susana Mogyca; http://lattes.cnpq.br/3136809931691012; STRINGHINI, José Henrique; http://lattes.cnpq.br/8505634095383289In 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.
