| The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a variety of end-products such as food, energy, and fiber; thus, taking into account the similarity in end-product of different crops (e.g.: sunflower, peanuts, or soybean for oil) it is possible to evaluate which crops require less energy per functional unit, such as starch, oil, and protein. This information can be used in decision-making about policies for food safety or bioenergy. In this study, 23... |

| Abstract The objective of the present study was to characterize maize silage according to chemical composition, maize silage yield, as well as their predicted milk production. A search was made on studies related to maize silage yield, density, chemical composition (DM, CP, NDF, starch), and dry matter digestibility (DMD). In this study, 41 maize varieties from temperate regions and 101 maize varieties from tropical origin were analyzed. The net energy of lactation (NEL Mcal/kg DM), kilograms of milk per t of silage (kg of milk/t DM), and kilograms of milk per hectare of silage (kg of milk/ha) were determined. A cluster (CL) analysis was performed, and six CL of maize silage were obtained. The CL1 included digestibility for dry matter, crude protein,... |

| A cana-de-açúcar é de grande interesse no período da seca por propiciar alta produção de carboidratos e ser armazenada naturalmente com pequena queda do valor nutritivo. Diante disto, com o objetivo de identificar variedades de cana-de-açúcar indicadas para alimentação animal, realizou-se um experimento conduzido na Estação Experimental Barra do Choça e no campus de Itapetinga pertencente à UESB. Foram avaliadas 23 variedades no delineamento em blocos casualizados, com duas repetições, colhidas 16 meses após o plantio. Foram determinadas características agronômicas e químico-bromatológicas. Quanto às características estudadas, observou-se diversidade entre as variedades. Os teores encontrados para matéria mineral, extrato etéreo e proteína bruta foram... |

| Foram avaliados os efeitos do emurchecimento e da inclusão de raízes (0, 15, 30 e 45% da matéria natural) sobre a composição químico-bromatológica e parâmetros fermentativos de silagens da parte aérea da mandioca. O emurchecimento influenciou significativamente o teor matéria seca (MS), a densidade e o pH das silagens em todas as doses de adição de raízes. A inclusão destas elevou o teor de MS em 0,128 e 0,261%, a densidade em 1,79 e 4,54 kg m-3 e, reduziu o pH em 0,0007 e 0,0062, respectivamente nas silagens emurchecidas ou não, a cada unidade percentual de adição de raízes. A exceção dos teores de fibra detergente ácida (FDA) e lignina, todos os demais parâmetros apresentaram interação significativa entre o emurchecimento e a inclusão de raízes. O... |

| The cotton plant contains fruits called capsules or bolls, in which the cotton fiber grows, and after the growth stages, the fibers appear through separating the carpels. This research investigated the required force to pick the cottonseed from four cotton variety (Golestan, Khorshid, Sajedi, and Kashmar) in three levels of moisture (three harvesting times) and three revolutions (1500, 2500 and 3500 rpm). To measure this force, designed and manufactured a device similar to a spindle cotton picker and using the actual needle of John Deere machine 9920. The bolls were tested in different revolution and moisture levels with the device. The results of experiments showed that the cross-effects of variety on speed, harvesting time on variety and harvesting... |

| The objective of this project was to separate distillers dried grains with solubles (DDGS) into high protein and high fiber fractions, in order to improve value and utility as a livestock feed. This project used a laboratory-scale cylindrical blower (Iowa blower) and a laboratory-scale gravity table (Whippet V-80 separator, Sutton, Steele & Steele, Inc.). The raw DDGS was sieved into multiple streams using 10 mesh, 20 mesh and 40 mesh screens. The 10-20 mesh fraction and 20-40 mesh fraction were then run on the blower and the separator separately, using the same settings for air velocity in the range of 0.32 m/sec to 3.06 m/sec. A high protein fraction was achieved (37.13% db) for the 10-20 mesh fraction with an air velocity of 2.42 m/sec by the... |

| BACKGROUND: The Mediterranean diet is a healthy diet with positive scientific evidence of preventing chronic diseases. Bioactive components support the healthy properties of the Mediterranean diet. Antioxidants and fiber, two components of the Mediterranean diet, are key functional nutrients for healthy eating and nutrition. Wine grape pomace is a rich source of these dietary constituents and may be beneficial for human health. Our hypothesis was that the intake of red wine grape pomace flour (WGPF) prepared from red wine grapes (Cabernet Sauvignon variety) reduced the metabolic syndrome in humans. To evaluate the effect of WGPF on components of metabolic syndrome we design a 16-week longitudinal intervention study. Thirty-eight males, 30-65 years of age,... |

| The aim of this work was to study the source of the açaí residue for its possible commercial applications by characterizing the fruit (fresh and dry mass), and performing an anatomic study of the pericarp from which were identified the origin of the anthocyanins, and fatty acids, and fibers; also the vascular system, its fibers constituents and fibrils were characterized. It was concluded that anthocyanins were located on the epiderm and external parenchyma, and that solids retained on the sieve come from the sclerenchyma, and that the fatty acids come from the storage parenchyma. The vascular tissue was formed by the fibers around 20 mm length. The length distribution of the fibrils had a mean length of 580µm. |
