| La domesticación de hongos silvestres comestibles, particularmente de Morchella es actualmente una necesidad, generada por su demanda en los mercados nacionales e internacionales. Sin embargo, no se tiene establecido un procedimiento para su producción comercial y el 100% de la producción comercializada proviene de recolecta del bosque, ocasionando la degradación del recurso. Por tanto, para contribuir a la solución de esta situación se realizó la presente investigación, la cual integra dos etapas, una de reflexión teórica y la otra de estudios experimentales. En la primera, se efectuó un trabajo de análisis, identificando el papel del enfoque de Agroecosistemas y una propuesta conceptual de la domesticación para el caso de los hongos silvestres... |

| The present study aimed to evaluate the effects of different nutritional strategies in growing and finishing phases on the carcass morphometry of 24 crossbred steers, ½ Holstein/Zebu, slaughtered at 15 months of age and 395.0kg live weight. In the growing phase, animals were maintained grazing on Brachiaria brizantha, receiving two levels of energy supplementation in quantities equivalent to 0.5 or 1.0% live weight. Then, animals were finished in feedlot receiving diets composed of 50 or 80% concentrate. The percentage of primary cuts was not influenced by feed levels in the growing and finish phases. The high supplementation level in the growing phase resulted in a higher (p < 0.05) carcass length (134.48 vs. 131.43 cm). The food levels did not... |

| The objective of this study was to evaluate the nutritional and productive characteristics of primiparous lactating cows grazing on tropical pasture, using different levels of crude glycerin in the supplement. The experiment was conducted at Rancho Santana farm, located in Jequié city, Bahia, Brazil, in the period from December 21, 2010 to March 16, 2011. Ten ¾ Holstein × ¼ Dairy Gyr lactating primiparous cows, with 109±24 days of lactation and a mean age of 30±6 months and mean body weight of 426.2±68.29 kg were distributed into five treatments, using two simultaneous 5 × 5 latin squares. Treatments consisted of inclusion levels (0, 94, 191, 289, 389 g/kg dry matter basis) of crude glycerin in the supplement. Intake, digestibility, milk production and... |

| ABSTRACT Forty male Naemi lambs were used to evaluate the effect of total mixed rations (TMR) alone or in combination with supplementation of alfalfa hay offered at different schedules on growth, carcass characteristics, and meat quality. Lambs at the age of three months, with an average weight of 28.85±1.09 kg, were randomly selected and distributed into four different feeding systems, 10 lambs each, as follows: TMR diet (control); TMR plus 100 g alfalfa hay; TMR plus 200 g alfalfa hay every two days; and TMR plus 300 g alfalfa hay every three days. The TMR and fresh drinking water were offered ad libitum. Lambs in the treated groups (with alfalfa hay) had significantly higher body weight, body weight change, dry matter intake, and feed conversion ratio... |

| ABSTRACT This study was conducted to evaluate the influence of management tools - daily pasture allowance and corn silage supplementation - during periods of forage shortage on the metabolism of dairy cows grazing low-mass pasture in temperate regions. Forty lactating Holstein cows were used during an experimental period of seventy days (April 15 to June 23, 2012). Blood metabolites and milk production were determined in fall-calving dairy cows grazing under two daily pasture allowances (PA) (moderate, 17 kg vs. high, 25 kg dry matter (DM)) and supplemented with corn silage (CS) (low, 4.5 kg vs. high, 9.0 kg DM). All cows received 3 kg DM of concentrate. Plasma concentrations of β-hydroxybutyrate (BHBA), non-esterified fatty acids (NEFA), and urea were... |

| The objective of this study was to evaluate non-carcass components of goats submitted to grazing in the Caatinga rangeland and supplemented with spineless cactus (Nopalea cochelinifera Salm Dick), Jitirana hay (Merremia aegyptia L. Urban) and Mororó hay (Bauhinia cheilanta Bong Stend). Thirty male goats (castrated), with no defined breed, with an initial mean body weight of 19 ± 0.35 kg and approximately 90 days of age were used. The treatments consisted of grazing without supplementation (GWS), grazing + Jitirana hay (GJ); grazing + Jitirana hay + spineless cactus (GJSC); grazing + Mororó hay (GM); grazing + Mororó hay + spineless cactus (GMSC). The means of the variables were tested by Tukey's test at 5% probability. The goats fed GWS, GJSC, GM and GMSC... |

| O uso de suplementos concentrados e a adequação proteica nestes suplementos podem ser importantes ferramentas para os sistemas de produção de ovinos em pastagens tropicais. O presente trabalho teve por objetivo avaliar diferentes fontes proteicas no suplemento concentrado de ovinos mantidos em pastagens irrigadas de Tifton 85. Os tratamentos avaliados foram: animais não-suplementados (controle), farelo de soja, ureia e torta de algodão, no suplemento concentrado múltiplo (20% de proteína bruta e 74% de nutrientes digestíveis totais). A quantidade de concentrado fornecida diariamente foi de 0,180 kg animal-1. Foram utilizados 28 ovinos machos castrados, mestiços Santa Inês x sem padrão racial definido, com peso corporal inicial de 28 kg. O período... |

| ABSTRACT Aiming at breeding heifers with 14-15 months of age, 100 Hereford calves were subjected to different feeding systems. Heifers grazed on a natural pasture in early winter, fed or not a supplement (14% crude protein; 72% total digestible nutrients), were transferred to a ryegrass pasture for 73 days, and then returned to a natural pasture for 15 days until the beginning of the breeding season. During the last 15 days on ryegrass pasture and the 15 days of the return to the natural pasture, half of the heifers of the two previous systems were offered the supplement, thereby establishing four feeding treatments. Heifers supplemented during the second period, independently of supplementation during the first grazing period, presented higher average... |

| ABSTRACT A 10-week study was conducted to evaluate the effect of feed allowance and graded levels of dietary methionine (Met) on growth performance of Litopenaeus vannamei. Juvenile shrimp of 1.83±0.14 g were stocked in 42 outdoor green-water tanks of 1 m3 under 120 shrimp m−2. Animals were fed under two feed allowances, regular and 30% in excess. Five diets with 30 g kg−1 fishmeal were designed to contain 318±2 g kg−1 crude protein and a minimum amount of protein-bound Met. To achieve graded levels of dietary Met, a control diet with 4.6 g kg−1 Met or 8.9 g kg−1 methionine + cysteine (M+C) was supplemented with 1.2, 2.2, 3.2, and 4.2 g kg−1 of DL-methionyl-DL-methionine to result in total dietary Met of 5.6, 6.9, 7.9, and 9.2 g kg−1 (10.0, 11.2, 12.1, and... |
