O estudo foi conduzido na Fazenda Experimental do Moura ? UFVJM, localizada no munic?pio de Curvelo MG. Foi adotado um delineamento inteiramente casualizado, em esquema fatorial 3 x 3, sendo tr?s esp?cies de leguminosas forrageiras tropicais (Estilosantes Campo Grande, Puer?ria e Macrotiloma) e tr?s fases de desidrata??o (1? fase: 0 a 8h; 2? fase: 12 a 20h; e 3? fase: 24 a 32 horas de secagem), com quatro repeti??es. As diferen?as entre as m?dias foram analisadas pelo teste Tukey (p<0,05). As forrageiras foram cortadas manualmente, picadas e espalhadas sobre lonas pl?sticas para otimiza??o da desidrata??o. A desidrata??o das forrageiras teve in?cio ?s 9:00 do dia 21 de fevereiro. O procedimento de amostragem foi realizado a cada 2 horas, no primeiro dia, e a cada 4 horas, no segundo e terceiro dias. Nos tempos previamente estabelecidos, as amostras foram identificadas, pesadas e submetidas a estufa de circula??o for?ada a temperatura de 55oC por 72h para a pr? secagem. Para a determina??o da curva de desidrata??o e quantifica??o da perda de nutrientes durante a desidrata??o foram realizadas as seguintes an?lises bromatol?gicas: mat?ria seca (MS), mat?ria mineral (MM), fibra em detergente neutro corrigido para cinza e prote?na (FDNcp), fibra em detergente ?cido (FDA), extrato et?reo (EE), prote?na bruta (PB), nitrog?nio n?o proteico (NNP) e carboidratos sol?vel (CHOS). Foram tamb?m estimados os teores de carboidratos totais (CHT), carboidrato n?o fibroso (CNF) e nutrientes digest?veis totais (NDT). Durante a curva de desidrata??o foi observada maior efici?ncia de secagem para as esp?cies Estilosantes e Puer?ria. Ao fim dos tempos de avalia??o, o Macrotiloma apresentou teor de umidade superior ao recomendado para armazenamento. As tr?s leguminosas apresentaram aumento crescente do teor de MS em fun??o do tempo de desidrata??o. N?o foram observados efeitos para os teores de MM, FDNcp, FDA, CNF, CHT e NDT no decorrer da curva de desidrata??o. O Estilosantes e o Macrotiloma apresentaram perda nos teores de EE na primeira fase, o Macrotiloma apresentou os maiores teores de EE entre as esp?cies estudadas. A Puer?ria apresentou acr?scimo no teor de PB da primeira fase para a segunda e foi leguminosa que apresentou maior teor desse nutriente entre as leguminosas estudadas. As tr?s leguminosas apresentaram redu??o nos teores de NNP na primeira para a segunda fase da curva de desidrata??o. O Macrotiloma foi a ?nica leguminosa que apresentou redu??o dos teores de CHOS durante a curva de desidrata??o e a leguminosa que apresentou os maiores teores deste constituinte. O Estilosantes foi a leguminosa que apresentou a desidrata??o mais eficiente durante o processo de fena??o, chegando mais rapidamente ao teor de umidade recomendado para o armazenamento.Submitted by Jos?

Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2016.The objective with this study was to evaluate the dehydration curve and nutrient loss of three tropical forage legumes during haymaking. The study was conducted at the Experimental Farm of Moura- UFVJM, located in Curvelo MG. A completely randomized design in a factorial 3 x 3, three species of tropical forage legumes was adopted (Stilosanthes Campo Grande, Kudzu and Macrotyloma) and three stages of dehydration (Phase 1: 0 to 8 am; 2nd phase: 12 to 20h; and phase 3: 24 to 32 hours of drying), with four replications. Differences between means were analyzed by the Tukey test (p <0.05). The foragers were manually cut, chopped and spread on plastic sheeting to optimize the dehydration. The dehydration of fodder began at 9:00 am on 21 February. The sampling procedure was performed every 2 hours on the first day and every 4 hours in the second and third days. In the time previously established, samples were identified, weighed and subjected to forced circulation oven temperature 55?C for 72h for pre-drying. For the determination of the dehydration curve and quantifying the loss of nutrients during dehydration were performed the following chemical analysis: dry matter (DM), mineral matter (MM), neutral detergent fiber corrected for ash and protein (NDFap), acid detergent fiber (ADF), ether extract (EE), crude protein (CP), non-protein nitrogen (NPN) and soluble carbohydrates (SCHO). It was also estimated the total carbohydrates (TCH), non-fibrous carbohydrate (NFC) and total digestible nutrients (TDN). During dehydration curve was greater drying efficiency for Stilosanthes and Kudzu species. At the end of the assessment times, Macrotyloma presents moisture content higher than recommended for storage. The three legumes have increasing the dry matter content due to the dehydration time. No effects for MM, NDF, FDA, CNF, CHT and NDT during the dehydration curve. The Stilosanthes and Macrotyloma showed loss in EE levels in the first phase, the Macrotyloma showed the highest EE levels among the studied species. The Kudzu has increased in the first phase CP content for the second and was legume with the highest content of this nutrient among the studied legumes. The three legumes have reduced the NPN content in the first to the second phase of dehydration curve. The Macrotyloma was the only legume that decreased the SCHO contents during dehydration curve and legumes that presented the highest levels of this constituent. The Stilosanthes was legume that presented the most efficient dehydration during the haying process, coming faster to the moisture content recommended for storage.porUFVJMA concess?o da licen?a deste item refere-se ao ?
