Objetivou-se determinar o teor de energia metabolizável e os coeficientes de digestibilidade de duas amostras de triticale e uma de cevada. Foram utilizados 32 suínos machos imunocastrados com peso de 53,44 ± 3,61kg. O experimento foi realizado na Embrapa Suínos e Aves, em Concórdia – SC. A dieta referência (DR) consistiu-se de formulação para fase de crescimento, baseada em milho e farelo de soja suplementada com minerais e vitaminas e, três tratamentos com as amostras de alimentos-teste, sendo que a cevada substituiu 30% e o triticale substituiu 40% da DR, no qual foram utilizadas duas cultivares de triticale, a BRS Surubim Copercampos e BRS Zenite Cotrisal. O experimento teve a duração de 12 dias, sendo sete dias de adaptação dos animais às gaiolas de metabolismo e às dietas e cinco dias de coleta total de fezes e urina. Para determinar o início e o final do período de coleta de fezes foi adicionado marcador fecal (óxido férrico 1,5%) nas dietas. Os dados obtidos foram Proteína Bruta (PB) 12,23%, Fibra Bruta (FB) 3,44%, Extrato Etéreo (EE) 1,08%, Matéria Mineral (MM) 2,13%, Coeficiente de Digestibilidade Aparente de Matéria Seca (CDAMS) 87,79%, Coeficiente de Digestibilidade Aparente de Matéria Orgânica (CDAMO) 87,96%, Coeficiente de Digestibilidade Aparente da Proteína Bruta (CDAPB) 86,07%, Energia Digestível (ED) 3.899 Kcal/Kg MS e Energia Metabolizável (EM) 3.713Kcal/Kg MS da cevada. Do Triticale BRS Surubim obteve-se PB 11,90%, FB 1,71%, EE 1,44%, MM 1,64%,CDAMS 85,96 %, CDAMO 86,46%, CDAPB 79,12%, ED 3.798 Kcal/Kg MS e EMn 3.628 Kcal/Kg MS. Já para a cultivar BRS Zenite Cotrisa de triticale obteve-se os valores de PB 11,57%, FB 1,37%, EE 0,84%, MM 1,70%, CDAMS 88,27 %, CDAMO 88,88%, CDAPB 82,20%, ED 3.769 Kcal/kg MS e EMn 3.589 Kcal/Kg MS. A cevada e as duas cultivares de triticale apresentam bons níveis nutricionais e energéticos e podem ser utilizados como alimentos alternativos na dieta de suínos, em substituição ao milho. |

The aim was to determine the metabolizable energy content and digestibility coefficients of two samples of triticale and one of barley. Thirty-two immunocastrated male pigs weighing 53.44± 3.61 kg were used. The experiment was carried out at Embrapa Swine and Poultry, in Concórdia - SC. The reference diet (RD) consisted of a formulation for the growth phase, based on corn and soybean meal supplemented with minerals and vitamins, and three treatments with test feed samples, with barley replacing 30% and triticale replacing 40% of the RD, in which two triticale cultivars were used, BRS Surubim Copercampos and BRS Zenite Cotrisal. The experiment lasted 12 days, with seven days for the animals to adapt to the metabolism cages and diets and five days for total collection of feces and urine. To determine the start and end of the faeces collection period, faecal marker (1.5% ferric oxide) was added to the diets.The data obtained were Crude Protein (CP) 12.23%, Crude Fiber (CF) 3.44%, Ethereal Extract (EE) 1.08%, Mineral Matter (MM) 2.13%, Apparent Digestibility Coefficient of Dry Matter (CDAMS) 87.79%, Apparent Digestibility Coefficient of Organic Matter (CDAMO) 87.96%, Apparent Digestibility Coefficient of Crude Protein (CDAPB) 86.07%, Digestible Energy (DE) 3. 899 Kcal/kg DM and Metabolizable Energy (ME) 3,713Kcal/KG DM of barley. The BRS Surubim triticale obtained 11.90% CP, 1.71% BF, 1.44% EE, 1.64% MM, 85.96% CDAMS, 86.46% CDAMO, 79.12% CDAPB, 3,798 Kcal/kg DM ED and 3,628 Kcal/kg DM MEn. For the BRS Zenite Cotrisa triticale cultivar, the following values were obtained: CP 11.57%, BF 1.37%, EE 0.84%, MM 1.70%, CDAMS 88.27%, CDAMO 88.88%, CDAPB 82.20%, ED 3,769 Kcal/kg MS and EMn 3,589 Kcal/kgMS. Barley and the two triticale cultivars have good nutritional and energy levels and can be used as alternative feed in pig diets to replace corn. |
