“…Several methods have been investigated for the use of açaí agroindustrial residue, including energy generation and fertilizer production (Teixeira et al 2002). The use of açaí seed has aroused the interest of animal producers, and, in some cases, it has been empirically tested in animal feed (Gomes et al 2012).…”

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.

“…The high levels of fiber (NDF + ADF) and lignin in seed açai were also described by Altman (1956), results similar to those obtained by Rodrigues Filho et al (1993), both analyzing the species Euterpe oleraceae. Most alternative foods are waste from industry, with high levels of fiber, which requires in-depth studies from the scientific community that accurately determine the role of fiber in the nutrition of monogastrics (Gomes et al, 2012). However, poultry and pigs use the fibrous fraction of food as an energy source (from 5 to 30% of maintenance energy) (NRC, 1998).…”

“…They also stated that the use of diets containing 10% of açaí seed is in fact a viable alternative for the production and the reduction of the negative impacts generated by the residues on the environment. Gomes et al (2012) evaluated the inclusion of açaí seed in ruminant diets and obtained satisfactory results in the inclusion of up to 15% in the sheep diet. Guimarães and Storti Filho (2004) evaluated the performance of tambaquis fed with açaí seed and shell, as the main alternative product after the use of the pulp.…”

“…The wine from the processing of the fruit pulp is the main source of food for many locals. Research shows that the seeds, as a by-product obtained in the extraction of the pulp, correspond to about 90% of the total weight of the fruits and can be used in animal feed (Guimarães and Storti Filho, 2004;Gomes et al, 2012;Arruda et al, 2018), especially in circumstances where an attempt is being made to increase the participation of fiber in the diet (Townsend et al, 2001).…”

The objective was to evaluate the potential of using Euterpe precatoria Mart seed to feed pigs. Diets were prepared with different levels of inclusion of açaí seed (0; 7.5; 15 and 22.5%), resulting from the extraction of the stern. Forty four castrated weighing approximately 15 kg and average 60 days of birth pigs were used, distributed in four groups according to the level of inclusion of açaí kernel. After 56 days of feeding, the pigs' performance and economic viability were evaluated. There was no significant difference in daily feed intake, final weight, weight gain and feed conversion between groups of treatments to the statistical test. The inclusion of up to 22.5% of açaí kernels in the diet did not result in a statistical difference in the thickness of backfat, percentage of lean meat and carcass yield, however it increased the gross and partial net revenue and the economic viability in the test, demonstrating the potential from açaí seed for the production of slow-growing crossbred pigs in the Amazon region, especially in properties that exploit the sustainable extraction of açaí and that can reduce the impact of the fruit residue on the environment when using this by-product in animal feed. Reducing production costs and allowing the promotion of sustainable development in the Amazon region.

“…Lambs fed elephant grass showed greater dry matter intake compared to sugarcane diets (P<0.05). This may be related to its greater apparent digestibility results of an elevated ruminal retention time, which stimulates the satiety center and limits feed intake (Gomes et al, 2012). Additionally, sugarcane diets have high content of lignin which affects its degradability rate, decreasing dry matter intake as result of high ruminal transit time (Cutrim et al, 2012).…”

This study was untaken to evaluate the effects of diets based on elephant grass or sugarcane as roughage and corn meal or rice bran as energy concentrate on carcass characteristics, meat quality, and the rack of lamb cut characteristics. Thirty-six lambs of undefined breed initially weighing 19.77±1.99 kg were used. A completely randomized design with eight treatments in a 2×2×2 factorial arrangement: two roughage (elephant grass or sugarcane), two concentrates (rice bran or corn meal), and two feeding levels (ad libitum or 60% of ad libitum) was performed. The nutrient intake was greater (P<0.05) in treatments with corn meal and elephant grass and at 4.96% of body weight feeding level. No interactions between roughage sources, concentrate sources, and feeding level was observed (P<0.05). The intake of dry matter was greater in lambs fed corn meal (P<0.05). No difference was observed on quality meat parameters (P>0.05), except for collagen solubility (P<0.05). Corn meal provided a noticeably greater percentage of protein (P<0.05), while rice bran promoted a greater fat deposition (P<0.05) in the rack of lamb. The use of sugarcane and rice bran as alternative foods for feedlot sheep is a viable strategy, because they do not decrease the quantitative and qualitative traits of sheep carcass and meat.
