“…Unlike the results observed in this experiment, Bellaver et al (2001) observed that diets with 5% of viscera and bone meal in substitution of soybean meal resulted in better broiler performance in the growing phase, but diets with 3% of viscera and bone meal did not affect performance until 21 days of age (Bellaver et al, 2005). Laboissiere (2008) verified that the best performance in the pre-starter phase was achieved with 9.0% of viscera and bone meal obtained from different processing systems (varying cooking temperature and moisture).…”

“…Including animalorigin byproducts in poultry diets can cause an amino acid imbalance, mainly in the non-essential ones (MacLeod, 2001) if their levels are not analyzed. However, these ingredients can result in low feed cost, especially when the ideal protein concept based on digestible amino acids is used (Vieites et al, 2000;Bellaver et al, 2005;.…”

-The use of viscera and bone meal in poultry pre-starter and starter diets and its effects on performance, digestive organ development and digestibility and nutrient retention were evaluated. In the first assay, 280-day-old Avian Cobb ® chicks were allotted in four experimental groups with five replicates of 14 birds each, in the pre-starter phase; in the second assay, 280 eight-day-old Avian Cobb 48 ® chicks were allotted in four experimental groups with five replicates of 12 birds each. The experimental diet consisted of increasing levels of viscera and bone meal: 0% (control diet), 3%, 6% and 9% in pre-starter (Assay 1) and starter (Assay 2) diets, to meet nutritional requirements and feed composition proposed by the Brazilian Tables, all of them isonutritive and isoenergetic. A metabolic assay was developed and the total excreta collection was performed from the 4 th to the 7 th days in Assay 1 and from the 14 th to the 17 th days in Assay 2. On these days, one chick per experimental unit, representing the mean body weight of the parcel, was euthanized to perform digestive organ

“…These ingredients contain amino acids, energy, calcium and phosphorus in balanced amounts. In practical view, for nutritionists, animal origin by-products and fats which are substituted by vegetable oil, soybean meal and dicalcium phosphate and other supplements can result in higher feeding costs (Bellaver et al, 2005).…”

“…In the experiments performed by Longo et al (2005), performance of chicks in pre-starter ration was not affected by the protein source fed, but this effect did not persist in the subsequent raising period. Rations containing these ingredients, when formulated based on ideal protein concept, result in better broiler performance (Cancherini et al, 2004;Bellaver et al, 2005).…”

-Two experiments were carried out (pre-starter and starter phases) to evaluate the effect of feather and blood meal on performance, organ development and digestibility and retention of nutrients in broilers. In the first experiment, it was used 280 birds and in experiment 2, it was used 240 birds. The experimental diets were formulated with four levels of feather and blood meal (0%, 2%, 4% and 6%) all of them isonutritive and isoenergetic. A metabolic assay was developed on the 4 th and 7 th days of age in experiment 1 and on the 14 th and 17 th days of age in experiment 2. In these periods, one bird per experimental unit was sacrificed for determination of morphometry of the digestive organs. In experiment 1, in which it was evaluated the pre-starter phase, there was a negative linear effect of the levels of feather and blood meal on weight gain and intake in 1-21 day of age period. By using feather and blood meal in the diet, it was observed a linear effect on digestibility coefficient of dry matter, nitrogen and ether extract; there was a quadratic effect on retention of dry matter and nitrogen and linear effect on the retention of ether extract. However, performance of birds in the starter phase (experiment 2) was not affected by levels of feather and blood meal used in the diet. Coefficient of digestibility of dry matter and ether extract and retention of ether extract were affected. In both phases, mortality and morphometric data of digestive organs were not influenced by the levels of meal in the diet. Formulation of diets with up to 6% feather and blood meal for chickens in the pre-starter phase (from 1 to 7 days) is not a good alternative because it worsens performance of birds. However, from the initial phase (from 8 to 21 days), the use of feather and blood meal in the diet is viable. Feather and blood meal can be used at levels 3.0 or 4.0% for broilers in the pre-starter and starter phase.

Resumo -O objetivo deste trabalho foi rastrear a inclussão de farinhas de origem animal em rações para frango de corte com ou sem levedura de cana-de-açúcar e farelo de trigo, por meio da análise do músculo peitoral das aves pelas técnicas dos isótopos estáveis de carbono e nitrogênio. Foram utilizados 210 pintos machos (Cobb), com um dia de idade, distribuídos aleatoriamente em sete tratamentos de 30 aves cada, tendo sido um tratamento controle (dieta vegetal) e seis com inclusão de farinha de carne e ossos bovina ou farinha de vísceras de aves na dieta, com ou sem levedura de cana-de-açúcar e farelo de trigo. Aos 42 dias de idade, foram abatidas quatro aves, por tratamento, escolhidas ao acaso, cujo músculo peitoral foi retirado para análise da razão isotópica. Os resultados obtidos foram submetidos à análise multivariada. Os tratamentos experimentais diferiram do tratamento controle, e foi identificada a inclusão de farinha de origem animal, pelas técnicas dos isótopos estáveis, mesmo com inclusão de levedura ou farelo de trigo na dieta.Termos para indexação: Gallus gallus, carbono-13, certificação, farinha de carne e ossos, farinha de vísceras, nitrogênio-15. Traceability of animal byproducts in diets containing yeast and wheat meal for broilersAbstract -The aim of this paper was to trace the presence of meals from animal origin, in diets for broilers with or without yeast and wheat meal, through the analysis of breast muscle, by using carbon and nitrogen stable isotope techniques. Two hundred ten male chicks (Cobb) one-day old were randomly distributed to seven treatments (30 birds each), with a control diet (exclusively vegetal), and six diets containing meat and bone meal or poultry offal meal, with or without yeast and wheat meal in their compositions. At 42 days of age, four broilers randomly chosen, by treatment were slaughtered, and their breast muscles were collected for isotopic ratio analysis. The isotopic results were analyzed by multivariate statistical analysis of variance. The treatments differed from the control and the inclusion of meals of animal origin was identified by stable isotope techniques, even when there was yeast or wheat meal included in the diet.
