Pesquisa do Estado de Minas Gerais (FAPEMIG) / O objetivo deste experimento foi avaliar as caracter?sticas fermentativas e qu?mico-bromatol?gicas da silagem de Capim-Elefante (CE) contendo diferentes n?veis de inclus?o de casca de maracuj? (MC) e casca de abacaxi (AC), dos coprodutos do abacaxi (AM), do morango (MO) e da goiaba (GO) in natura. Utilizou-se neste experimento, n?veis crescentes de adi??o destes coprodutos (0,0%; 12,5%; 25,0%; 37,5% e 50,0%) em rela??o ? mat?ria natural na silagem de CE cortado aos 150 dias de idade. Este material foi ensilado em silos laboratoriais e, ap?s 180 dias, os silos foram abertos e foram determinados os teores de mat?ria seca (MS), carboidratos sol?veis (CHOS), potencial hidrogeni?nico (pH), nitrog?nio amoniacal em porcentagem do nitrog?nio total (N-NH3), prote?na bruta (PB), prote?na insol?vel em detergente neutro em porcentagem do nitrog?nio total (PIDN/NT), prote?na insol?vel em detergente ?cido em porcentagem do nitrog?nio total (PIDA/NT), extrato et?reo (EE), fibra em detergente neutro (FDN), fibra em detergente ?cido (FDA), nitrog?nio insol?vel em detergente neutro na mat?ria seca (NIDN), nitrog?nio insol?vel em detergente ?cido na mat?ria seca (NIDA), hemicelulose (HCEL), celulose (CEL), lignina (LIG), mat?ria mineral (MM), f?sforo (P) e c?lcio (Ca). Para a avalia??o do efeito dos tratamentos, utilizou-se o delineamento experimental inteiramente casualizado em esquema fatorial 5x5 (coproduto x n?vel de inclus?o). Devido ? intera??o entre as silagens com os n?veis de inclus?o dos coprodutos (P<0,0001), as silagens adicionadas com cada coproduto foram avaliadas individualmente, exceto para o Ca, que n?o se observou efeito dos coprodutos, dos n?veis de inclus?o e da intera??o (P>0,05). De acordo com as equa??es de regress?o para os par?metros de qualidade, as silagens podem ser consideradas de muito boa qualidade. Quanto a composi??o bromatol?gica, a inclus?o de n?veis crescentes dos coprodutos favorece o valor nutritivo das silagens de capim-elefante, exceto o GO, que por sua influ?ncia negativa nas fra??es fibrosas pode interferir no consumo e na digestibilidade destes alimentos pelos animais. Os par?metros analisados permitem concluir que, a inclus?o de todos os coprodutos in natura durante a ensilagem do capim-elefante, exceto o GO, s?o recomendados em todos os n?veis avaliados, possibilitando maior per?odo de utiliza??o do capim-elefante na forma de silagem. / Disserta??o (Mestrado) ?

Was used in this experiment increasing levels of addition of these co-products (0.0%, 12.5%, 25.0%, 37.5% and 50.0%) in relation to natural matter in silage cut CE at 150 days of age. This material was ensiled in laboratory silos, and after 180 days, the silos were opened and contents were determined for dry matter (DM), soluble carbohydrates (CHOS), hydrogen potential (pH), ammonia nitrogen as a percentage of total nitrogen (N -NH3), crude protein (CP), neutral detergent insoluble protein as a percentage of total nitrogen (NDIP / NT), acid detergent insoluble protein as a percentage of total nitrogen (PIDA / NT), ether extract (EE), fiber neutral detergent fiber (NDF), acid detergent fiber (ADF), neutral detergent insoluble nitrogen in dry matter (NDIN), acid detergent insoluble nitrogen in dry matter (NIDA), hemicellulose (HCEL), cellulose (CEL), lignin (LIG), mineral matter (MM), phosphorus (P) and calcium (Ca). For assessing the effect of treatment, we used the completely randomized design in a factorial 5x5 (x coproduct inclusion level). Due to the interaction between silage with inclusion levels of co-products (P <0.0001), silages added with each coproduct were evaluated individually, except for Ca, which no effect of co-products, the levels of inclusion and noted interaction (P> 0.05). According to the regression equations for the parameters of quality silage can be considered very good quality. Regarding the chemical composition, the increasing levels of coproducts favors the nutritive value of elephant grass silages, except GO, which in its negative influence on fiber digestibility may interfere with the intake and digestibility of feed for animals. The analyzed parameters allow to conclude that the inclusion of all coproducts in nature during ensiling of elephant grass, except GO, are recommended at all levels evaluated, allowing a greater period of use of elephant grass as silage.

Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2010. / ABSTRACT The objective of this study was to select clones of sweet potato with potential for use in human and animal feed. The work was carried out at the Vegetable and Dietetic Techniques Laboratory and Biomass Technology of Cerrado of Campus JK - UFVJM in Diamantina-MG. We evaluated the total yield of roots and commercial yield of roots, average weight of commercial roots, shape of roots, soil resistance to insects, dry matter content of roots and total carotenoids. Besides these characteristics there were also evaluated the physical and sensorial characteristics: the squash color, texture and softness, sweetness of the squash, cooking time and acceptability of sweet potato clones in the roots. In the aim to study the potential use of these clones in animal feed there were evaluated the yield of green matter, dry matter content and yield of dry mass of branches. The silage of the branches was evaluated for dry matter, crude protein, ADF, NDF, TDN, pH, Phosphorus, Calcium and Sodium. The experiment was conducted in a randomized block design (RBD), including 12 clones and 4 replications. The plots consisted of one row 4.5 m long, using the 1.0 m spacement between rows by 0.30 m between plants, totaling 15 plants per plot. For the sensorial analysis were used 40 untrained tasters for each clone. The clones are part of the germplasm bank of UFVJM, as follows: BD-06, BD-25 BD-15 BD-38, Batiste, BD-TO-31, BD-67 BD-45 BD-42, BD-54 and Pink and White Brazlandia. There were observed significant differences between the clones for the characteristics of commercial yield, resistance to insects, dry matter content and total carotenoids in roots of sweet potato clones. The evaluated clones showed similar characteristics of yield when compared to commercial cultivars Pink and White Brazlandia. The clones BD-25 BD-54 BD-31-TO and Batiste scored in evaluation for resistance to insects of soil below 2.0 and were considered resistant to soil insects. Clones BD-54 BD-31-TO, Batiste and BD-45 had high dry matter content in roots. The highest content of carotenoids in roots was obtained by clone BD-67. Clones BD-06, BD-38, Batiste, BD-TO-31, BD-67 BD-42 BD-54 and Pink and White Brazlandia had a level of acceptability above 70%, being accepted by consumers. The clones showed productivity of green mass and dry mass of branches similar to Pink and White Brazlandia commercial cultivars. There was no difference in yield of green mass and dry weight of branches among the clones of sweet potato. There were no differences between the clones on the crude protein content of silage forms. The branches of sweet potatoes in the majority of the clones showed potencial use for animal feed, either as fresh as in the form of silage.
