Resumo: | The objective of this work was to evaluate the supplementation of an enzymatic complex based on xylanase, β-glucanase and phytase in light commercial egg laying feeds at peak egg production,performance and egg classification. A total of 288 laying hens of the Hy-Line W36 breed were used in a completely randomized design in split plot with four treatments and six replicates of 12 layer each in four periods of 21 days each. The experimental rations were formulated based on corn and soybean meal, consisting of four types of ration: CP ration - positive control (100% recommended metabolizable energy without enzymes), CN ration - negative control, reductions in 75 kcal of metabolizable energy, 0.12 percentual points (pp) of Ca and P available, CN Ration + 60 g/t Enzyme Complex and CN Ration + 100 g/t Enzyme Complex. The enzyme complex was composed by: xylanase = 12,000 u/g; beta-glucanase = 2500 u/g and phytase = 5000 u/g. The variables evaluated were: average egg production (egg%/layerday), mean egg weight (g), mean feed intake (g/layer/day), feed conversion per egg mass, and classification according to weight. There was no interaction between the treatments and the evaluation periods (P> 0.05). It is possible to observe that the egg production was influenced by the nutritional reductions of the rations and the inclusion of 100 g/t of the enzymatic complex made it possible to recover the egg production rate, matching the layers of the positive control treatment (P<0.01). Feed intake was higher (P<0.05) for birds receiving 100 g/t enzyme complex compared to hens fed with ration without addition of enzyme complex (negative control). The weight of the eggs responded (P<0.01) to the nutritional reductions of the rations, being lighter in the negative control treatment, but with recovery when adding 100 g/t enzyme complex. The feed conversion was worse (P<0.05) for laying hens fed the feed with 60 g/t of the enzymatic complex tested, mainly due to the lower egg production observed in this treatment. The use of 100 g/t of the xylanase, beta-glucanase and phytase-based enzyme complex for feed formulations with nutrient reductions at 75 kcal ME/kg, 0.12 pp Ca and 0.12 pp P is recommended for laying hens Egg production in order to maximize performance and improve the classification of eggs produced. |

Foram utilizadas 288 poedeiras, com idade inicial de 25 semanas, da linhagem Hy-Line W36, distribuídas em delineamento inteiramente casualizado em esquema de parcelas subdivididas no tempo, com quatro tratamentos e seis repetições de 12 aves cada em quatro períodos de 21 dias. As rações experimentais foram formuladas à base de milho e farelo de soja: Ração CP - controle positivo (100% energia metabolizável recomendada, sem enzimas), Ração CN - controle negativo, constituído por reduções em 75 kcal de energia metabolizável/kg de MS; 0,12 pontos percentuais (pp) de Ca e de P disponível, Ração CN + 60 g/t de complexo enzimático e Ração CN + 100 g/t de complexo enzimático. O complexo enzimático foi à base de: xilanase = 12.000 u/g; β-glucanase = 2.500 u/g e fitase = 5.000 FTU/g. As variáveis avaliadas foram: produção média de ovos (% ovos/ave/dia), peso médio dos ovos (g), consumo médio de ração (g/ave/dia), conversão alimentar por massa de ovos (g/g) e classificação dos ovos de acordo com o peso. Não houve interação entre os tratamentos e os períodos de avaliação (P>0,05). É possível observar que a produção de ovos foi influenciada pelas reduções nutricionais das rações e a inclusão de 100 g/t do complexo enzimático possibilitou a recuperação na taxa de produção de ovos, igualando às poedeiras do tratamento controle positivo (P<0,01). O consumo de ração foi 1,5% maior (P<0,05) para as aves que receberam 100 g/t de complexo enzimático em comparação as poedeiras alimentadas com ração sem adição de complexo enzimático (CN) (98,66 vs 97,20 g/ave/dia). O peso dos ovos respondeu (P<0,01) as reduções nutricionais das rações, sendo mais leves no tratamento CN, mas com recuperação ao se adicionar 100 g/t de complexo enzimático (58,46 vs 59,29 g). A conversão alimentar foi 2,3% pior (P<0,05) para as poedeiras que receberam a ração com adição de 60 g/t do complexo enzimático em relação à ração controle (1,75 vs 1,71), em decorrência, principalmente, da menor produção de ovos verificada. Recomenda-se o uso de 100 g/t do complexo enzimático a base de xilanase, β-glucanase e fitase para rações formuladas com reduções nutricionais de 75 kcal de energia metabolizável/kg de MS, 0,12 pp de cálcio e 0,12 pp de fósforo disponível, para poedeiras comerciais leves em pico de produção de ovos com objetivo de maximizar o desempenho e melhorar a classificação dos ovos produzidosInstituto de Zootecnia2019-03-29T16:49:09Z2019-03-29T16:49:09Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfABREU, M.
