Açaí seed bran in the feed of slow-growth broilers

Abstract

The aim of this study was to analyze the potential use of açaí seeds as an alternative ingredient in the feed of slow-growth broilers until 28 days of age. We carried out a bromatological analysis of fractions of the açaí fruit. The açaí seed without mesocarp was the best choice for formulation of the açaí seed bran (ASB), which was evaluated in terms of bird performance and economic viability of the supplemented feed. A total of 416 male chicks of the French Red-Naked Neck lineage were used in a completely randomized design with four treatments (0, 2, 6 and 10% inclusion of ASBin the feed) with eight replicates each. The results indicated that ASB can be included in proportions of up to 10% in the diet of slow growth broilers at early development stage without impairing performance. The 10% inclusion level also was economically equal to the control treatment, representing a viable alternative for broiler production, with potential for reduction of the negative impacts generated by açaí residue in the environment.

Açai Seeds (Euterpe oleracea Mart) Are Agroindustrial Waste with High Potential to Produce Low-Cost Substrates after Acid Hydrolysis

“…Importantly, when a dried material is used for the purpose of releasing fermentable sugars through acid hydrolysis, moisture becomes a preponderant factor, as high values may dilute the acid concentration, decreasing the hydrolysis efficiency, and values < 10% are the most applicable [ 12 , 13 ]. The total protein values found in this work (4.6%) were similar to those found in other studies (1.7–4.3%) [ 6 , 7 , 8 , 9 ], and the total lipid values (1.9%) were similar to those found by Ferreira et al (1.70%) [ 8 ]. Additionally, based on the pH and total acidity values ( Figure 1 ), the dried açai seeds used in this study can be considered a low acidic product.…”

Farelo de açaí (Euterpe precatoria) como alimento alternativo em dietas para poedeiras comerciais leves

“…A polpa de açaí é o produto mais importante obtido do processamento do fruto do açaí (Menezes et al, 2008), porém representa apenas 10% da massa total do fruto, sendo as sobras descartadas como resíduo, representando um volume considerável de resíduos anualmente produzidos e descartados de forma inadequada sem entrar em ciclos de reaproveitamento ou economia circular (Jensen et al, 2008). Arruda et al (2018), Rufino et al (2020a,b) e Rufino et al (2021), utilizando o farelo de açaí em dietas de aves, relataram que uma inclusão moderada pode proporcionar bons teores de fibras, além de causar efeito positivo no desempenho e nas funções digestivas. No entanto, ao adicionar alimentos ricos em fibras em dietas de não ruminantes, os efeitos nutricionais, fisiológicos e de desempenho podem ser variáveis (Mateos et al, 2012;He et al, 2015), principalmente devido à quantidade de celulose incluída, composição e estrutura da fibra utilizada e como essa fibra está associada aos demais nutrientes (Praes et al, 2014;Yokhana et al, 2015;Lannuzel et al, 2022).…”

“…Other potential use of açaí seeds is as an alternative ingredient in the feed of slowgrowth broilers, representing a viable alternative for broiler production, with potential for reduction of the negative impacts generated by açaí residue in the environment (ARRUDA et al, 2018).…”
