“…These results are consistent with the findings of Barbosa et al (2012), who observed that the supplementation of enzyme blends to diets with reduced mineral and energy levels promoted similar feed intake and weight gain that broilers fed a standard diet during the starter phase. Brito et al (2006), using an enzyme complex containing amylase, protease, and xylanase, observed increased weight gain and improved feed conversion ratio in broilers between 1 to 21 days of age, as opposed to the findings of the present experiment. In addition, Leite et al (2011), who evaluated the same enzyme complex as the current study, found better feed conversion ratio 21-d-old broilers.…”

An experiment was conducted with the purpose of evaluating enzyme blends on the performance, carcass traits, and bone mineralization of broilers. In total, 928 one-day-old Cobb 500 male chicks of were used. A completely randomized design with four treatments with eight replicates of 29 birds each was adopted. The evaluated treatments were: 1-Positive Control (PC), feed containing the nutritional recommendations of the genetic company's manual; 2-Negative Control (NC), feed with reductions of 75 kcal/kg AME and 0.10 and 0.12 percent points of phosphorus and calcium, respectively; 3 -NC + enzyme blend (amylase + β-glucanase, xylanase, and phytase; 250 g/t of feed) and 4 -NC + enzyme complex (phytase, amylase, xylanase, glucanase, pectinase, cellulase, and protease; 200 g/t of feed). Birds fed the diet with reduced nutrient levels (NC) presented the worst performance (p<0.05). The supplementation of the enzyme blend promoted similar (p<0.05) weight gain and feed conversion ratio as those obtained with the PC diet during the period of 1-21 days of age. During the phase of 22-42 days and the entire experimental period, weight gain and feed conversion ratio improved with the use of the enzyme combinations compared with the NC group, but remained lower than the PC group. Enzymes combinations did not affect (p>0.05) carcass or parts yields. The broilers fed the reduced-nutrient and energy diet presented lower (p<0.05) tibial ash, calcium, and phosphorus contents that the other treatments. The use of enzyme combinations improved the performance of broilers fed diets with reduced nutrient and energy levels.

“…Já Campello et al (2009) verificaram aumento do pâncreas em frangos de corte, dos 22 aos 42 dias de idade, que receberam rações com soja crua a partir do nível de 10,58%, o que confirma as informações da literatura consultada de que o pâncreas é o órgão mais afetado pelos principais fatores antinutricionais contidos em leguminosas (Brito et al, 2006;Leite et al, 2012). As aves utilizadas no presente trabalho apresentam características genéticas diferentes das dos frangos de corte, de crescimento rápido; portanto, as respostas também diferem em relação à tolerância aos Tabela 4.…”

“…Os efeitos dos inibidores de proteases em animais não ruminantes alimentados com leguminosas cruas geralmente são observados em alterações metabólicas do pâncreas, como o aumento da secreção enzimática, com consequente hipertrofia e hiperplasia do órgão (Brito et al, 2006;Leite et al, 2012). Para tentar amenizar esse problema, as sementes de feijão têm sido submetidas ao tratamento térmico, que, porém, encarece o custo das rações e, portanto, o custo final da produção de frangos (Hajos & Osagie, 2004).…”

Resumo -O objetivo deste trabalho foi avaliar os efeitos da substituição do farelo de soja pelo feijão guandu cru na alimentação de frangos caipiras criados em sistema semi-intensivo. Foram utilizados 525 frangos de corte da linhagem Caipira Pesadão, com idade inicial de 35 dias, distribuídos em cinco tratamentos com cinco repetições de 21 aves cada um. Os tratamentos consistiram na substituição de 0, 5, 10, 15 e 20% do farelo de soja pelo feijão guandu cru moído. Foram avaliados o ganho de peso, o consumo de ração, a conversão alimentar, o rendimento de carcaça e de cortes, o peso do pâncreas e a qualidade da carne. A substituição do farelo de soja pelo feijão guandu em até 15,45%, nas dietas de frangos caipiras de corte, com idade de 57 a 71 dias, não altera o ganho de peso. O aumento dos níveis de feijão guandu na ração não afeta o rendimento de carcaça, o peso do pâncreas e os parâmetros de qualidade da carne.Termos para indexação: Cajanus cajan, alimento alternativo, aves caipiras, desempenho, rendimento de carcaça. Raw pigeon pea in the diet of free-range broilers reared in a semi-intensive systemAbstract -The objective of this work was to evaluate the effects of replacing soybean meal by raw pigeon pea in the diet of free-range broilers reared in a semi-intensive system. Five hundred twenty-five broilers of the Caipira Pesadão lineage were used, with initial age of 35 days, distributed in five treatments with five replicates of 21 birds each. Treatments consisted of the replacement of 0, 5, 10, 15, and 20% of soybean meal by ground raw pigeon pea. Weight gain, feed intake, feed conversion, carcass and cuts yield, pancreas weight, and meat quality were evaluated. Replacing soybean meal by pigeon pea in up to 15.45% in the diet of free-range meat broilers, with age of 57 to 71 days, does not change weight gain. Increasing levels of pigeon pea in the diet do not affect carcass yield, pancreas weight, and meat quality parameters.Index terms: Cajanus cajan, alternative feed, free-range birds, performance, carcass yield. IntroduçãoA criação de aves para a produção de carne do tipo caipira, no sistema semi-intensivo, é um dos segmentos da avicultura que tem se mostrado promissor (Santos et al., 2005). A carne produzida apresenta sabor diferenciado, que agrada ao paladar de consumidores à procura de alimentos com maiores atributos de qualidade (Carrijo et al., 2010). No entanto, o desafio nesse tipo de criação é tornar a produção mais eficiente, ao diminuir os custos com a alimentação, sem perder as características dos produtos.O aumento na demanda por fontes de proteína e o seu alto custo tem estimulado pesquisas que buscam novas alternativas para substituir as tradicionais fontes proteicas, principalmente a do farelo de soja. O feijão guandu [Cajanus cajan (L.) Millsp.] é uma dessas alternativas, pois apresenta boas quantidades de proteína bruta, que variam entre 22 e 27% (Onu & Okongwu, 2006;Iorgyer et al., 2009;Amaefule et al., 2011). Além disso, é uma leguminosa resistente à seca, fator importante para sua c...

“…This suggests that the EC partially increased the availability of dietary non-starch polysaccharides, particularly those present in soybeans, which is rich in oligosaccharides. Several studies reported the capacity of enzymes to improve the nutrient digestibility of corn-and soybean mealbased diets (Brito et al, 2006;Rutherfurd et al, 2007;West et al, 2007;Viana et al, 2009), reducing the influence of antinutritional factors found in these feedstuffs. Pugh and Charlton (1995) included a multienzyme complex, consisting of cellulose, protease, and xylanase (1.0 kg/ton), in broiler diets based on soybean meal and they obtained an increasing by 7.2% in metabolizable energy values.…”

Two trials were performed to evaluate the effects of an enzyme complex (EC) on broiler performance, metabolizable energy, and phosphorus and nitrogen balance. In the first trial, 960 one-day-old male Cobb broilers were randomly distributed in a 3 x 2 factorial arrangement (three nutritional levels and the inclusion or not of EC), totaling six treatments with eight replicates of 20 birds per pen, and reared until 42 days of age. The control diet was formulated to meet the broilers' nutritional requirements. The other diets contained reduced available phosphorus (P), metabolizable energy, and amino acid levels, considering 100% and 150% of the EC nutritional matrix. The inclusion of the EC (200 g/ton) resulted in better broiler performance, improving weight gain in 4% and feed conversion ratio in 3% (p<0.05). In the second trial, 240 male broilers were randomly distributed into the same treatments with eight replicates of five birds per cage. The method of total excreta collection was used. There was an interaction (p<0.05) between diets and EC for P intake, nitrogen (N) intake, and N retention. The EC supplementation improved nitrogen-corrected apparent metabolizable energy values in 2.02% (p<0.05). Significant effects were observed on phosphorus and nitrogen balance (p<0.05). Phosphorus retention improved in 10.26%, nitrogen retention increased in 5.3%, while nitrogen excretion decreased in 3.3%. Based on the results of the present study, we recommend the addition of 200 g/t of the enzyme complex to broiler diets, considering nutrient reduction based on 100% of the EC nutritional matrix.
