| The objectives of this research were to evaluate leaf consumption and the developmental time of the larvae of Erynnyis ello (L., 1758) (Lepidoptera, Sphingidae) reared on cassava, in order to obtain information for the integrated management of this pest. The larvae were reared on excised cassava leaves in Petri dishes and later in gerbox, and kept in chambers at 24 ± 2 ºC and 75 ± 10% RH. The total leaf area consumed by the larva to complete its development was 589.67 cm²; each of the five instars consumed, respectively: 1.89 cm²; 5.74 cm²; 17.48 cm²; 76.66 cm²; and 487.90 cm². The consumption by the first three instars was insignificant, and did not reach 5% altogether; the 4th represented 13%; the 5th presented a consumption significantly higher, about... |

| The objective of this study was to evaluate performance and biometrics of lambs fed different sources of forage. Twenty-four six-month-old Santa Inês female lambs were randomly allocated to four experimental diets and housed in individual stalls. They weighed on average 26.35±0.20 kg. The diets were coast cross hay (HAY), cassava hay (CAS), dehydrated by-product of pea crop (PEA) and saccharin (SAC). The diets were formulated with the same amount of protein and energy with fixed levels of forage (60%) and concentrate (40%). Adaptation to the diet took 7 days, with 45 days on experiment. Weights and biometric measurements were obtained every fortnight and feed intake three times a week. Rights half-carcasses were weighed and sectioned into retail cuts, rib,... |

| In this study, the somatic embryogenesis and regeneration of Cigana Preta plants from shoot apices and immature leaves taken from plants cultivated in vitro were examined. To embryo induction the explants were cultivated in Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) or 4-amino-3,5,6-trichloropicolinic acid (Picloram) at concentrations of 8.0 and 12 mg L-1. To development of embryos two media cultures with different concentration of BAP (D1 or D2) were evaluated. Embryos in the cotyledonary stage were incubated in germination medium containing MS salts and vitamins, 2.0 µM copper sulfate, 2.4 g L-1 of Phytagel® and 1.77 µM BAP. The highest frequency of calluses and the greatest number of embryos per explant were... |

| Manipueira, wastewater of cassava (Manihot esculenta) processing, can be treated by anaerobic biodigestion. To study the start-up process of a plug-flow digester for manipueira treatment, this work consisted of two stages: gradual decrease of the hydraulic retention time (HRT) to the preset time of 4 days or maintaining a fixed HRT of 4 days with gradual increase of the substrate concentration. A digester of 1980 mL capacity was opperated, at constant temperature (32 ± 1º C), with substrate pH corrected between 5.5 and 6.0. The first stage had durations of 16.6; 13.6; 11.6; and 9.6 days and the organic loads were 3.1; 2.0; 2.3; and 2.9 COD L-1 d-1, (chemical oxigen demand) respectively. The second stage was characterized by a fixed HRT (4 days) and organic... |

| Starch factories generate large amounts of cassava solid waste. A small amount is utilized for animal feed but most of it is discharged with deleterious effects to the envirounment. A edible food with a high content of insoluble dietary fiber (60.9%), named "partially hidrolyzed cassava waste" (PHCW), was prepared from industrial cassava solid waste by an enzymatic process. PHCW or wheat bran (WB) were fed to model rats and both promoted digestive function effects, but PHCW produced the greatest effect. The insoluble fiber constituent from PHCW (and not the soluble fiber), promoted the greatest fecal bulking, fecal weight and defecation frequency in rats, as compared to WB. Such results indicate that the partially hydrolyzed cassava waste presents... |
