Two trials were conducted: (1) to determine the chemical composition, digestibility of nutrients and energy of cashew nut meal (CNM); and (2) to evaluate the effects of increasing its levels (0, 5, 10, 15, 20 and 25%) in diets for growing rabbits on performance, carcass characteristics and economic evaluation. The digestibility assay utilized 24 rabbits (55 days of age), distributed in a completely randomized design with two treatments and 12 repetitions, with one reference and another test feed composed of 70% basal diet and 30% CNM. The digestibility of dry matter, crude protein and gross energy from CNM were, respectively, 76.61, 61.71 and 56.53%. The digestible dry matter, digestible protein and digestible energy were, respectively, 74.28, 16.97 and 3,549 kcal/kg. The performance assay utilized 120 rabbits, with an average of 45 days of age and weight 1090 ± 151g, distributed in a completely randomized design with six treatments and 10 repetitions with two rabbits of the same sex per cage. The inclusion of CNM above 5% promoted a linear reduction in feed intake and improved feed conversion, without affecting weight gain and carcass characteristics to the 20% level of inclusion. There was also a linear reduction in feed cost per kilogram of weight gain and linear improvement in rates of economic efficiency and cost index up to 25% CNM inclusion. Based on these findings – and to not hurt performance – it is recommended to include up to 20% CNM in rabbits' diet.

A trial was conducted to evaluate quality of quail eggs from two companies (A and B) at two storage times (5 and 15 days after packing). A total of 480 eggs were kept at room temperature and distributed in a completely randomized design in 2x2factorial arrangement (companies and storage time). The results indicated that trays from company B presented higher weight, as well as mean egg weight. However, the eggs in trays from company A showed greater uniformity. Evaluating the external quality, we found that above 90% of eggshell were considered with total integrity, and no difference for this characteristic between companies was found. The eggs from company A presented lower average weight in comparison to those from company B, regarding storage time. No differences were observed between eggs from companies A and B for Haugh unit value. Storage time of 15 days after packing promoted reduction in Haugh unit value in comparison to those stored for 5 days. Quail eggs from company A presented lower variation in weight, although heavier eggs are produced by company B. Internal quality of quail eggs from both companies was similar. Storage time affected eggs quality.

O experimento foi realizado para avaliar o efeito de diferentes níveis de inclusão do farelo de babaçu (0, 3, 6 e 9 e 12%) em dietas à base de milho e farelo de soja para frangos de corte de 21 a 42 dias de idade sobre o desempenho produtivo, rendimento de carcaça e avaliação econômica. Alojaram-se trezentos frangos (machos e fêmeas), linhagem Hubbard, distribuídos em um delineamento inteiramente casualizado com cinco tratamentos (0, 3, 6 e 9 e 12%) e cinco repetições de doze aves (seis de cada sexo) por unidade experimental. As rações experimentais foram isonutritivas. A inclusão de até 12% de farelo de babaçu nas dietas não prejudicou as variáveis de desempenho (consumo de ração, ganho diário de peso e conversão alimentar) e não influenciou no peso aos 42 dias e no rendimento de carcaça (P>0,05). Entretanto, os resultados de receitas bruta e líquida refletem que o uso de farelo de babaçu pode ser vantajoso em períodos de entressafra do milho e da soja, permitindo-se incluir em até 6% nas dietas para frangos de corte dos 21 aos 42 dias de idade.PALAVRAS-CHAVES: Babaçu, economia, frangos, produção. The experiment was carried out to evaluate the effect of different levels of babassu meal inclusion (0, 3, 6, 9 and 12%) in diets with corn and soybean meal for broilers of 21 to 42 days of age on the productive performance, carcass yield and economic evaluation. 300 Hubbard lineage broilers (both genders) were accommodate and distributed in completely randomized design with five treatments (0, 3, 6 and 9 and 12%) and five replicates of 12 animals (6 of each gender) for experimental unit. The inclusion of up to 12% of babassu meal in the diets did not decrease the performance variables (ration consumption, weight daily gain and feed conversion), neither affecting the weight at 42 days of age and the carcass yield (P>0.05). However, the gross and net incomes reflect the use of babassu meal can be advantageous in periods when corn and soybean meal prices were high, including in up to 6% in broilers’ diets of the 21 to 42 days of age. KEY WORDS: Babassu, broiler, economy, production.
