“…Exogenous enzyme addition to cereal diets have been shown to improve both nutrient digestibility and growth performance in pigs (Yin et al, 2000). Exogenous enzymes with xylanase activity increased digestibility of nutrients during lactation in sows; however, a similar response was not seen during gestation (de Souza et al, 2007).…”

A total of 200 (Large White 3 Landrace) sows were used in a 39-day study to evaluate the effects of feeding a non-starch polysaccharide (NSP)-hydrolysing enzyme multicomplex (Rovabio R Excel) in conjunction with a high-or reduced nutrient-density diet during lactation on sow body condition, feed intake and progeny performance. Eight sows were selected each week for 25 weeks, blocked by parity and BW into groups of four, and within the block randomly assigned to one of the four treatments (n 5 50/treatment). Treatments were: (1) LND: low energy (13.14 MJ of DE/kg), low CP (15%) diet; (2) LND 1 RE: LND with 50 mg/kg NSP-hydrolysing enzyme; (3) HND: high energy (14.5 MJ of DE/kg), high CP (16.5%) diet; and (4) HND 1 RE: HND with 50 mg/kg NSP-hydrolysing enzyme. Sows were fed treatment diets from day 109 of gestation until the day of subsequent service. Between weaning and re-service, Rovabio R Excel addition to LND diets resulted in an increase in energy intake; however, a reduction was observed when supplemented to the HND diet (P , 0.05). The inclusion of Rovabio R Excel increased feed and energy intake during week 3 (days 15 to 21) of lactation (P , 0.05). Sows fed diets supplemented with Rovabio R Excel had greater back-fat depth at weaning and service (P , 0.05); however, the magnitude of change in back-fat depth during lactation and from farrowing to service was not different between treatments. Feeding the HND diet increased energy intake before farrowing, throughout lactation and during the weaning to service interval (P , 0.01); however, overall, average daily feed intake tended to be reduced (P , 0.10). At service, sows fed the HND diet were heavier than sows fed the LND diet (P , 0.05); however, the magnitude of change in BW between treatments was not different. Feeding the HND diet to sows resulted in a tendency for heavier piglets at birth (P 5 0.10) that tended to grow at a faster rate and be heavier at weaning than piglets from sows fed the LND diet (P 5 0.06). These results indicate that NSP-degrading enzymes offer minimal benefit to sows and their progeny when fed before and during lactation; however, increasing energy intake of sows during lactation may beneficially affect progeny.

“…A adição de enzimas apropriadas é capaz de reduzir algumas das propriedades anti-nutricionais desses PNA da parede celular (Yin et al, 2000), diminuir a variação da qualidade nutricional das dietas, permitir digestão mais rápida e completa, diminuindo a excreção fecal de nutrientes e, conseqüentemente, a poluição ambiental, além de reduzir a incidência de fezes úmidas quando as aves são alimentadas com dietas de alta vicosidade (Bedford, 2000). A inclusão de enzimas exógenas nas dietas também pode reduzir o alto investimento energético do animal para a síntese enzimática.…”

RESUMO -O estudo foi conduzido com o objetivo de avaliar os efeitos da inclusão de farelo de trigo (FT) na ração com ou sem a suplementação de um complexo enzimático (CE) sobre o desempenho e a produção de ovos de frangas semipesadas na fase de produção. Foram utilizadas 288 frangas Lohmann Brown, distribuídas em delineamento inteiramente casualizado, em esquema fatorial 4 × 2, composto de quatro níveis de farelo de trigo (0, 3, 6 e 9%) na ração e da suplementação de complexo enzimático (0 ou 100 g/100 kg de ração), com oito tratamentos e seis repetições de seis aves. O complexo enzimático continha as enzimas β-galactosidase, galactomananase, xilanase e α-glucanase. O consumo de ração, o peso vivo final, a produção de ovos, o peso e a massa de ovos e a conversão por massa e por dúzia de ovos não foram afetados pela inclusão do farelo de trigo nas rações. A gravidade específica da casca dos ovos piorou com o aumento dos níveis de farelo de trigo nas dietas. Nenhuma característica foi afetada pela adição do complexo enzimático na ração, com exceção do peso do ovo, que melhorou de 62,74 para 64,28 g. Recomenda-se o uso de até 9% de farelo de trigo em rações para poedeiras em produção. A adição de α-galactosidase, galactomananase, xilanase e α-glucanase aumenta o peso dos ovos.Palavras-chave: alimento alternativo, enzimas exógenas, produção de ovos Wheat bran and enzymatic complex in the feeding of laying hens in the production phase ABSTRACT -The study was carried out with the objective to evaluate the effects of the inclusion of the wheat bran (WB) with or without supplementation of an enzymatic complex (EC) on the performance of semi-heavy hens in the eggproduction phase. A total of 288 Lohmann Brown pullets were used, distributed to a completely randomized design in 4 × 2 factorial arrangement, composed by four WB levels (0, 3, 6 and 9%) in the ration and enzymatic complex supplementation (0 or 100g/100 kg diet), with eight treatments and six replicates of six birds. The enzymatic complex contained the enzymes β-galactosidase, galactomananase, xilanase and α-glucanase. Feed intake, final body weight, egg production, egg weight, egg mass, egg mass feed conversion or egg dozen feed conversion was not affected by WB inclusion in the diets. Egg shell specific gravity deteriorated as WB levels increase in the diets. None of the characteristics was affected by the enzymatic complex supplementation, except for egg weight, that improved from 62.74 to 64.28 g. Then, the use up to 9.0% of wheat bran in the ration is recommended for semi-heavily chickens in the production phase. The supplementation of α-galactosidase, galactomannanase, xylanase and α-glucanase improve egg weight.

RESUMOForam avaliados os efeitos da inclusão do farelo de trigo (FT) com e sem a suplementação da ração com um complexo enzimático (CE), composto de amilase, protease e celulase, sobre o desempenho de frangas semipesadas (15 semanas de idade) e seu efeito residual na produção de ovos. Foram utilizadas 288 frangas, distribuídas em delineamento inteiramente casualizado, em esquema fatorial 4X2, sendo quatro níveis de FT e dois níveis de um CE na ração: 0 (controle), 10, 20 e 30% X suplementação com 0 ou 50g de um CE/100 kg de ração, resultando em oito tratamentos, com seis repetições. Na fase de crescimento, o consumo de ração, o ganho de peso, a conversão alimentar e o peso vivo foram melhores para as aves que receberam as dietas isentas de FT. A adição do CE diminuiu o consumo de ração nas dietas com 0 e 30% de FT. Durante a fase de produção, o uso do CE na ração de recria sem FT aumentou o peso vivo das aves, mas reduziu no nível de 30% de FT. A produção de ovos diminuiu no nível de 20% de FT quando a dieta foi suplementada com o CE. As conversões alimentares no nível de 10% de FT foram semelhantes ao controle. Observou-se efeito quadrático do nível de FT sobre a conversão por massa de ovos, que foi melhor com 8,01%. Portanto, recomenda-se até 8,01% de inclusão do farelo de trigo na ração de poedeiras semipesadas de 15 a 19 semanas de idade. Termos para indexação:Alimento alternativo, enzimas exógenas, produção de ovos. ABSTRACTThis study was carried out with the aim of evaluating the effects of the inclusion of the wheat bran (WB) and the addition of an enzymatic complex (EC), amylase, protease and celullase contained, on the performance of semi-heavily pullets from 14 weeks of age and its residual effect on egg-production phase. 288 pullets were used, distributed in a completely randomized design in a factorial arrangment 4X2, being the following levels of WB in the ration: 0 (control), 10, 20 and 30% X 0 or 50g of a EC/100 kg of diet, resulting in eight treatments, with six replicates of six birds. The EC contained the enzymes amylase, protease and celullase. In the growth phase, FI, WG, FC and LW showed better for the birds that received the diets without FT. The addition of the EC decreased the consumption in the diets with 0 and 30% of WB. During the production phase, the use EC in the level 0% of WB increased LW of the birds, but it reduced in the level 30% of WB. The production of eggs fell in the level of 20% of WB when the diet was supllementing with EC. The feed conversion in the level of 10% of WB was similar to the control. Quadratic effect of the level of WB was observed on the feed egg-mass conversion, that was better with 8,01%. Therefore, it is recommended up to 8.01% of inclusion of the wheat bran in the ration of semi-heavily pullets from 14 to 19 weeks of age.
