“…Dentre as espécies forrageiras nativas da caatinga destacase a Maniçoba (Manihot pseudoglaziovii) uma Euphorbiaceae tóxica quando verde, no entanto, produtora de um feno que pode ser utilizado na alimentação dos pequenos ruminantes (ARAÚJO et al, 2004;SILVA et al, 2007;CASTRO et al, 2007;FRANÇA et al, 2010).…”

ResumoA utilização de forrageiras nativas da Caatinga configura-se em alternativa para os sistemas de produção sustentáveis no Nordeste brasileiro. Objetivou-se avaliar a substituição total do feno de Tifton 85 pelo feno de Maniçoba, em dietas a base de palma forrageira, sobre os componentes do peso corporal de caprinos Moxotó. Os animais eram machos não castrados, pesando inicialmente 21,67±3,92 kg, confinados em baias individuais e abatidos após 58 dias de confinamento. O tipo de feno não influenciou (P>0,05) nenhuma das características de carcaça dos caprinos. Os animais apresentaram peso corporal ao abate médio de 21,83 kg e pesos médios de carcaça quente e fria de 9,83 kg e 9,21 kg, respectivamente. Os rendimentos de carcaça também não foram influenciados pelo tipo de feno (P>0,05) e apresentaram médias de 44,98% para carcaça quente e 42,11% para carcaça fria. A área de olho de lombo (AOL) e o índice de compacidade da carcaça apresentaram médias de 6,19 cm² e 0,159 kg cm -1 , respectivamente, e não sofreram influência do tipo de feno na dieta. Não foi observada diferença (P>0,05) entre as dietas para peso de órgãos e vísceras. A dieta Tifton 85 proporcionou maiores (P<0,05) pesos de pele. A substituição do feno de Tifton 85 pelo feno de Maniçoba, na dieta de caprinos Moxotó, não altera nenhum componente da carcaça, contudo em relação aos constituintes não carcaça, reduz o peso da pele. Palavras-chave: Buchada, carcaça, forragem nativa, Manihot AbstractThe use of native forages Caatinga set up as an alternative for the sustainable production systems in Northeast Brazil. This study aimed to evaluate the substitution of Tifton 85 hay by Maniçoba hay in the components of the body weight of Moxotó goats. The animals were steers, initially weighing 21.67±3.92 kg, housed in individual pens and slaughtered at 58 days of confinement. The type of hay did not influence (P>0.05) any of the carcass traits. The animals presented for slaughter average body weight of 21.83 kg, and average weights of hot and cold carcass of 9.83 kg and 9.21 kg, respectively. The carcass were not affected by the type of hay (P>0.05) and average 44.98% and 42.11% for hot cold carcass. The loin eye area (LEA) and carcass compactness index had averages of 6.19 cm² and 0.159 kg cm -1 , respectively, and did not influence the type of hay in the diet. There was no difference (P> 0.05) between diets for weight of organs and viscera. The diet Tifton 85 yielded higher (P<0.05) weights skin. Replacement of Tifton 85 hay by Maniçoba hay, the diet of Moxotó goats does not alter carcass component, but reduces the weight of the skin.

“…It is mainly consumed by low-income people as a staple food source in Africa and the Americas, and includes 99 species (Nassar, 2002). Studies of the vegetative and reproductive anatomical characteristics of Manihot have been conducted in the last decade, and have focused on the stem (Graciano-Ribeiro et al, 2009;Nassar et al, 2008Nassar et al, , 2010a, root (Bomfim et al, 2011a,b), egg cell (Hashimoto-Freitas and Nassar, 2013), and leaves (França et al, 2010). However, knowledge of Manihot petiole anatomy is limited.…”

Comparative petiole anatomy of cassava (Manihot) species

ABSTRACT. In this study, we describe the petiole anatomy of six wild cassava (Manihot) species, one hybrid, and two cultivars of Manihot esculenta, in order to identify their dominant anatomical patterns and relate them to possible adaptations to abiotic factors in the Cerrado biome. The median parts of several petiole samples were transversally and longitudinally sectioned and stained. The results include data for the taxonomic classification of the genus, including distinctive anatomical characteristics of hybrid varieties of cassava and wild species, such as the presence/ absence of trichomes and a hypodermis, layer type and number in the cortex, number of vascular bundles, cell types in the pith, and type of organization. Morphological analysis revealed differences in length and shape of the petiole insertion. The presence of trichomes, a hypodermis, the amount and type of supporting tissue in the cortex, as well as gelatinous fibers, may be related to drought tolerance.

“…The average lignin percentages of 11.0 and 17.10% respectively found by França et al (2010) and Barros et al (1990) can be explained by the phenological stage of the plant in the collection period, since in this study the EL presented an average of 11.8%, while LBS averaged 17.7%.…”

“…According to this author, the quality of this forage plant is higher after the beginning of the rainy period, which is also the ideal moment for haymaking because of the fewer indigestible components. França et al (2010) reported average NDF and ADF of 43.0 and 30.9% in a collection of leaves + branches for haymaking. Evaluating wild-cassava leaves and branches, Vasconcelos et al (2010) obtained mean percentages of 50.4 and 31.4% for NDF and ADF, respectively; these NDF values were much higher than those found in our study.…”

-The objective of this study was to evaluate the chemical composition of leaves of maniçoba (Manihot sp.) according to their development stage and their relationship with the soil characteristics. For this purpose, plants in their natural growth areas in the semiarid region of Paraíba State, Brazil, were sampled. Leaves of maniçoba collected in five different locations at four different development stages were harvested and characterized: expanding leaf, completely expanded leaf, leaf at the beginning of senescence and a pool (mixture of all leaves). The evaluated traits were: dry matter, crude protein, neutral detergent fiber, acid detergent fiber, neutral detergent insoluble protein, acid detergent insoluble protein, ash, lignin, cellulose, hemicellulose, nitrogen, potassium, phosphorus, sulfur and sodium. The experimental design adopted was completely randomized, in a 4 × 5 factorial arrangement: four leaf development stages and five locations, respectively; each plot had 10 replications. There was interaction effect between leaf development stage and locations on dry matter, crude protein, neutral detergent insoluble protein and acid detergent insoluble protein. The results for neutral detergent fiber of leaves at the beginning of senescence were higher than other treatments and similar to the pool, while the acid detergent fiber content of the leaves in early senescence was higher than those of other treatments, averaging 34.8%. Crude protein content had its highest percentage in expanding leaves, averaging 23.0%. Nitrogen, potassium and sodium data showed interaction between the leaf types and locations of harvest, while phosphorus and sulfur did not show interaction. The chemical and mineral composition of maniçoba leaves range according to their development phase and according to their soil and climatic conditions in places of natural occurrence, with a tendency towards reduction of nitrogen and phosphorus as they approach senescence.
