| Price-quality relationships for alfalfa hay were analyzed by hedonic pricing models using 1996-2001 Wisconsin auction data. Individual nutrients included in the analysis all affected alfalfa price, with acid detergent fiber accounting for the largest impact. Alternative pricing models, based on an aggregate quality index or detailed quality information, were similar in their ability to predict price. However, disaggregating price predictions to account for differences in relative feed value (RFV) and crude protein (CP) indicate that both RFV and CP are important determinants of price and that aggregating the two into a quality index is not warranted. |

| Para atenuar el daño provocado por los gorgojos de la alfalfa en la Argentina, el mejoramiento orientado al aumento del número de raíces laterales puede ser importante. Los objetivos de este trabajo fueron estimar bajo cuatro condiciones ambientales, componentes de varianza, heredabilidad en sentido amplio (H) y correlaciones entre biomasa aérea y caracteres de raíz en 10 poblaciones de alfalfa de grado 6 a 9 de reposo invernal, mejoradas por sistema de raíz ramificada en la E.E.A. Manfredi-INTA. Los caracteres evaluados fueron: rendimiento de biomasa promedio (BP), diámetro de raíz pivotante (DP), número de raíces laterales (NRLR), diámetro de raíces laterales (DRLR) y sistema radicular tipo ramificado (R). Hubo ausencia de correlación entre BP y los... |

| ABSTRACT This study was conducted to compare the applicability of non-feed removal (NFR) programs to induce molting in brown laying hens by feedusing alfalfa meal and barley grain on molting of instead of feed withdrawal in terms of performance, egg quality and profitability. A total of 240, 75-week-old Hy-Line brown laying hens were randomly divided into three groups as conventional feed withdrawal (CONV), and two non-feed removal programs using alfalfa meal (A+F) or barley grain (B+F), each containing 80 hens with 20 replicates (4 hens x 20 replicates = 80 hens). After 10 days of the induced molting the lowest body weight loss (20.01%) was found in the B+F method (p< 0.01). In the second cycle, onset of egg production days were significantly different... |

| The article deals with the connection between energy and economic indicators of crop production in the Czech Republic. Herein, a procedure for the determination of energy inputs and outputs from production based on soil-climatic conditions is outlined. For basic arable crops, other possibilities using the production in the energy sector as well as in relation to soil-climatic conditions are evaluated. The article reviews the production and economic parameters of crop production for potential energy use, such as natural production, energy production, electricity and operational profit. The maximum production parameters are achieved by sugar beet and, consequently, maize for silage. Other energy-efficient crops are alfalfa and clover, but with technological... |

| The objective of the present experiment was to compare the performance, egg quality and organ morphometrics of commercial layers submitted to alternative forced molting methods using dietary fibers. The experimental period included the phases of molting, rest, and second laying cycle (six periods of 28 days each). In the trial, 320 commercial Isa Brown layers with 72 weeks of age were distributed, according to a completely randomized experimental design into five treatments with eight replicates of eight birds each, totaling 40 experimental units. Molting was induced by feeding diets with the inclusion of alfalfa or soybean husks at 80% and 60% or feed fasting. Treatments were applied for 14 days. Performance and egg quality parameters were evaluated for... |

| Se evaluó el efecto de la adición de azufre y fósforo sobre la extractabilidad de Pb, Cd y Ni, y en la biodisponibilidad para maíz y alfalfa en el valle del Mezquital, Hidalgo. Se muestrearon los suelos de 13 sitios, se caracterizaron física y químicamente y se determinaron los elementos potencialmente tóxicos totales y extractables. De estos suelos se seleccionaron tres (Atitalaquia, Tlahuelilpan y Tepatepec) para establecer experimentos de equilibrio en el laboratorio. Los suelos se incubaron con dosis crecientes de azufre (0, 2, 4 y 6 t ha-1) y fósforo (0, 250, 500, 1000 y 2000 mg L-1), durante cinco y dos semanas, respectivamente. Se cuantificó la concentración de Pb, Cd y Ni, unidos a las diferentes fracciones del suelo (soluble, FI; intercambiable,... |
