The aim of this study was to evaluate the effect of different levels of crude protein (CP) and electrolyte balance (EB) of the feed of broilers. 480 male broiler of Cobb 500 strain were fed in the period 36 to 42 days of age with two basal diets, one with EB 200 and another with 240 mEq. kg-1, combined with CP levels of 18.00, 17.28, 16.56 and 15.84%. The reduction in CP levels had growing linear effect (P <...
This study aimed to evaluate the energetic efficiency in coffee drying (Coffee Arabica L.) with different combinations of revolving time in a fixed-bed coffee dryer. The experiment was conducted in July 2004 in Jesuítas – Paraná state/Brazil. The dryer featured a mechanic system with rotating blades to revolve of the product at different intervals. The drying air temperature was 75°C ± 5°C. The v...
This study aimed to evaluate the temperature reduction in the external parts of a fixed-bed coffee dryer, by means of different combinations of revolving times, using a noncontact thermometer. The experiment was developed in the month of June 2004 at a farm located in Jesuítas, Paraná State, Brazil. Coffee (Coffea arábica L.) variety IAPAR 59 was used. The dryer used was of the fixed-bed model, with metallic dr...
The aim of this study was to compare the efficiency of three estimate methods for reference evapotranspiration in comparison with the FAO Penman-Monteith equation. Meteorological data used in this study were collected from the IAPAR meteorological station, located in Palotina, Paraná State, Brazil. In order to estimate the reference evapotranspiration, data available from 1994 to 2003 were used. The performance...
This work aims at evaluating and analyze the thermal environment in different types of individual calves structures in summer and winter seasons. The treatments were consisted of: black globe directly exposed to the sun (T1); shade structure (T2); individual hut, open sides (T3); individual hut with three closed sides (T4). In order to evaluate the microenvironment of the treatments, the Black Globe and Humidit...
The agricultural ecosystem as a way of converting solar energy in products needs several energy sources, among those sources stood out fertilizers, agricultural defensives and others. These inputs are derived from fossils. In the present paper, the energy consumption involved in corn silage production in a non-tillage crop system, in São Miguel do Iguaçu, State of Paraná, Brazil, was studied. In the direct ener...
