1. DEVELOPMENT OF SOFTWARE FOR ANALYSIS OF BEHAVIOR AND WELFARE OF BROILERS
ABSTRACT The objective of this study was to develop a software based on image processing and computer vision techniques for monitoring the feeding/collective behavior of broilers (Cobb) and validate it based on the results obtained from the visual analysis of an expert. The visual analysis was performed based on the observation and quantification of behavior

2. THEORETICAL ANALYSIS AND EXPERIMENTAL STUDY ON THE PROCESS OF CONVEYING AGRICULTURAL FIBER MATERIALS BY SCREW CONVEYORS
ABSTRACT To improve the conveying efficiency and working stability of a screw conveyor, the feeding methods, running conditions and flow characteristics of materials were studied by theoretical analysis and experiments. The theoretical analysis results show that the screw conveyor runs more stably when the helix angle of the screw blade is equal to the movin

5. Overprice on purchase of replacement cattle and genetic group as variables of economic result in feedlot operations
ABSTRACT The objective of this study was to analyze the economic result of feedlot operation for three genetic groups of cattle (Nellore, Nellore crossing with other Zebuine breeds, and Dairy crossbred) as a function of the overprice on the purchase price of cattle to be feedlot-finished. The study involved data of 57,589 animals divided into 709 lots origin

6. A New Technique Using Axially Slotted Microstrip Line for Antenna Impedance Matching Designs
Abstract A new technique is presented for designing microstrip patch antennas with very good input impedance matching. The analysis is carried out for 1.78 GHz, 2.42 GHz and 3.46 GHz rectangular patch antennas printed on low-cost fiberglass substrates (FR-4), mounted on a ground plane and fed by a microstrip line. The antenna impedance matching is obtained u

7. First record of the sedge feeder Bactra verutana Zeller (Lepidoptera: Tortricidae) in Chile based on morphology and DNA barcodes
Abstract The sedge-feeding moth Bactra verutana Zeller, 1875 (Lepidoptera: Tortricidae: Olethreutinae: Bactrini), described from Dallas, Texas, USA, is widespread, recorded throughout much North America, Central and South America, including the Caribbean, and Africa. The species is recorded for the first time from Chile based on specimens collected in the co

8. Available space in feeders for housed sheep: social behavior and performance
ABSTRACT This study was designed to assess the effects of feeding space availability on social behavior and performance of housed crossbreed sheep through the use of three different types of feeders. Thirty-six crossbreed ewes (Santa Inês × Dorper; 2-3 years old) with initial body weight of 34.99±4.28 kg were randomly assigned to a 3 × 3 (feeder type ×

12. Biology and nutrition of Spodoptera frugiperda (Lepidoptera: Noctuidae) fed on different food sources
ABSTRACT: We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, ovipositio
