“…The moisture content was within the legal limits in Brazil for meal used in animal feeding (Brasil, 1988), that is, up to 12%. The obtained value was similar to that found by Geraseev et al (2011), 9.56%, and is different from the 10.32% determined by Pessoa et al (2013). CP content, 3.81%, was similar to that found by Oliveira, Guerra, Barros and Alves (2008) and by Geraseev et al (2011), 3.83 and 4.92%, respectively.…”

“…Data about the PPF inclusion in animal rations are scarce, and the few studies referred to the digestibility of PPF in goats (Geraseev et al, 2011) and in Nile tilapia (Pessoa et al, 2013). The cost of feeding represents the largest expense in an animal activity, and the pequi peel is intended for organic waste.…”

ABSTRACT. This study was carried out to evaluate the effects of pequi peel flour (PPF) in the diet of laying Japanese quails on their productive performance and on the quality and cost of the eggs produced. A total of 160 quail (Coturnix coturnix japonica) were distributed in a completely randomized design with four treatments and five replicates with eight birds each. Treatments consisted of different levels of PPF (0, 1, 2 and 3%) in a commercial diet based on sorghum. Evaluated parameters were productive performance (daily feed intake, laying rate, egg weight, egg mass and feed conversion rate), egg quality (yolk, albumen and eggshell weight and measures, yolk colour, ash and calcium content of eggshell, specific weight, Haugh unit, and nutrient content of the egg) and average cost of the production. PPF did not affect (p > 0.05) productive performance and nutritional composition, quality or average cost of the eggs; however, yolk colour was linearly increased (p < 0.05) with the PPF levels in the diets. It was concluded that PPF might be included in the commercial diets of Japanese quails up to 3% due to the improvement in yolk colour.Keywords: alternative feed for quails, Caryocar brasiliense Camb., pequi by-product.Farinha de casca de pequi em dietas para codornas japonesas RESUMO. Este estudo foi realizado para avaliar os efeitos da farinha de casca de pequi (FCP) em dietas para codornas japonesas sobre o desempenho produtivo, a qualidade dos ovos e o custo dos ovos produzidos. Foram distribuídas 160 codornas (Coturnix coturnix japônica) em um delineamento inteiramente casualizado com quatro tratamentos e cinco repetições com oito aves cada. Os tratamentos consistiram de níveis de FCP (0, 1, 2 e 3%) em ração comercial à base de sorgo. Os parâmetros avaliados foram o desempenho produtivo (consumo de ração diário, taxa de postura, peso do ovo, massa de ovo e conversão alimentar), a qualidade do ovo (peso e medidas de gema, albúmen e casca dos ovos, cor da gema e teores de minerais e de cálcio da casca do ovo, peso específico, unidade Haugh e teor de nutrientes dos ovos) e o custo médio da produção. A FCP não afetou (p > 0,05) o desempenho produtivo, a composição nutricional, a qualidade e o custo médio dos ovos, entretanto, a cor da gema aumentou linearmente (p < 0,05) devido ao aumento dos níveis de FCP nas dietas. Concluiu-se que a FCP pode ser incluída nas dietas comerciais para codornas Japonesas até 3% por melhorar a cor da gema.Palavras chave: alimento alternativo para codornas, Caryocar brasiliense Camb., subproduto do pequi.

“…Em relação aos parâmetros da MS, as folhas apresentaram maiores médias da fração prontamente solúvel (fração a) em relação aos resíduos, com valor inferior ao observado por Geraseev et al (2011) para a farelo de casca de pequi que foi de 48,16%. Em consequência das características das frações a, b e c da folha, registraram-se valores de degradação potencial (DP) e efetiva (DE) da MS de 44,44 e 34,24%, respectivamente, sendo estes valores superiores a DP e DE dos RL1, RL2 e RL3.…”

RESUMOObjetivou-se avaliar a composição química e a degradação ruminal da matéria seca, proteína bruta e fibra em detergente neutro das folhas e dos resíduos da industrialização da guariroba visando sua utilização na alimentação de ruminantes, utilizando-se o delineamento inteiramente ao acaso, com quatro tratamentos (Resíduo de Limpeza 1 (RL1); Resíduo de Limpeza 2 (RL2); Resíduo de Limpeza 3 (RL3)) e três repetições. A folha apresentou melhores teores de matéria seca (34,43%) e proteína bruta (10,40%) em relação aos resíduos de limpeza. A degradabilidade potencial e efetiva da matéria seca foi maior na folha da guariroba (44,44 e 34,24%), respectivamente. Houve diferença significativa (P < 0,05) entre os tratamentos para os teores de carboidratos não fibrosos e fração A + B1, sendo que os melhores resultados foram observados no resíduo RL3, 35,95 e 42,20%, respectivamente. Os resíduos estudados mostram particularidades quanto à composição química e à degradabilidade in situ, com características individuais que possibilitam a utilização na alimentação animal. Palavras-chave: Alimentos alternativos, composição química, degradabilidade, fermentação Nutritional value of industrial waste of guariroba (Syagrus oleracea) for ruminants ABSTRACTAimed to evaluate the chemical composition and ruminal degradation of dry matter, crude protein and neutral detergent fiber of the leaves and the industrialization of waste guariroba for their use in ruminant feed, using the completely randomized design with four treatments (Residue Cleaning 1 (RL1); Waste Cleanup 2 (RL2); Residue Cleaning 3 (RL3)) and three replications. The sheet showed better dry matter (34.43%) and crude protein (10.40%) compared to cleaning residues. The potential and effective degradability of dry matter was higher in leaf guariroba (44.44 and 34.24%), respectively. There was a significant difference (P < 0.05) between treatments for the carbohydrate non fiber and fraction A + B1, and the best results were observed in the residue RL3, 35.95 and 42.20%, respectively. The residues studied show peculiarities in chemical composition and in situ degradability, with individual characteristics enabling use in animal feed.

Background: The use of pequi by-product as animal feed is an appealing alternative to reduce overall production costs. However, little is known regarding its effects on animal performance as well as the ideal inclusion level in the diet. Objective: To evaluate performance, intake, and digestibility of confined lambs receiving diets containing different levels of pequi byproduct as a partial substitute for corn silage. Methods: The experiment was conducted in Curvelo, Brazil, using twenty-five crossbred Santa Inês male lambs (17.83 ± 1.73 kg) aged six months for 92 days. Increasing levels of pequi by-product (0, 6, 12, 18, and 24%) replacing corn silage were evaluated in a completely randomized design. Analysis of variance and regression were performed, with 5% significance level. Results: Inclusion of pequi by-product did not influence (p>0.05) average daily gain, total weight gain, or feed conversion ratio. No effect (p>0.05) was also observed on intake of dry matter, organic matter, ether extract, crude protein, neutral detergent fiber, total carbohydrates, and total digestible nutrients. However, a linear decrease was observed (p<0.05) in the apparent digestibility of dry matter, organic matter, ether extract, crude protein, neutral detergent fiber, total carbohydrates, and total digestible nutrients with increasing inclusion of pequi by-product. Conclusion: Pequi by-product is a potential substitute for corn silage in lamb diets because it does not influence animal performance and feed intake. However, digestibility decreases with increasing dietary inclusion levels of pequi by-product.
