1. NEURO-FUZZY MODELING OF EYEBALL AND CREST TEMPERATURES IN EGG-LAYING HENS
ABSTRACT Considering the challenges faced by poultry farming, this study aimed to develop a neuro-fuzzy model to predict eyeball and crest temperatures of egg-laying hens based on environmental conditions (dry bulb temperature and relative humidity). To develop the models and simulations, Matlab’s Fuzzy Toolbox® (Anfisedit) was used. Different configurati

2. AN EVALUATION OF THE THERMAL AND LUMINOUS ENVIRONMENT OF LAYING HEN AVIARIES EQUIPPED WITH LIGHT-EMITTING DIODE AND COMPACT FLUORESCENT LAMPS AND THEIR EFFECTS ON PRODUCTION AND EGG QUALITY
ABSTRACT The thermal and luminous conditions in aviaries affect the production and quality of eggs. Thus, the aim of the present study was to evaluate the thermal and luminous environment of commercial laying hen aviaries equipped with compact fluorescent (CF) and light-emitting diode (LED) lamps and their influence on egg production and quality. The study w

3. Effects of heat treatments and edible shell coatings on egg quality after storage at room temperature
Abstract The objective of this study was to evaluate the effect of thermal treatments using different water temperatures and immersion times, as well as the application of eggshell coatings using edible materials on eggshell quality after storage for 4 weeks at room temperature (22.8 ± 4.4 °C). A total of 180 brown fresh eggs were distributed in a complete

4. Physical-Chemical and Sensorial Quality of Eggs Coated With Copaiba Oil Biofilm and Stored At Room Temperature for Different Periods
ABSTRACT The present study aimed at evaluating the effects of a coating based on copaiba oil on the quality of eggs stored for different periods. Eggs were coated with copaiba oil solutions (4, 8, 12, 16, or 20% copaiba oil) or not (control) and stored for 1, 7, 14, 21, 28 or 35 days at room temperature. The following parameters were evaluated: egg weight lo

5. Método não invasivo para avaliação da movimentação embrionária de Caiman yacare (Daudin, 1802)
ABSTRACT This study aimed to evaluate the viability of using a non-invasive digital monitor to monitor heart rate (HR) and motility during the embryonic development of Pantanal alligator (Caiman yacare) using Egg Buddy ® , at different incubation temperatures. The collection of the eggs followed the Ranching system and egg identification, transportation, a

7. Influences of Different Coating Materials on the Quality Changes of Hardboiled Salted Duck Eggs under Ambient Storage
Abstract The present study investigated the influences of selected coatings (paraffin wax (PW), chitosan (CH), whey protein isolate (WPI), and soy protein isolate (SPI)) on the quality changes of hardboiled salted duck eggs when kept under ambient temperature (30±2 oC). At 5-day intervals for 15 days, samples were tested for color (L*, C*, and h˚), shell

8. Effects of The Dietary Supplementation of Layer Diets with Natural and Synthetic Antioxidant Additives on Yolk Lipid Peroxidation and Fatty Acid Composition of Eggs Stored at Different Temperatures and Duration
ABSTRACT In this study, the effects of the supplementation of natural and synthetic antioxidant additives in layer diets on egg weight loss, yolk lipid peroxidation (TBARS values) and fatty acid composition of eggs stored at different temperatures and duration were evaluated. In total, 112 48- weeks-old Bovans White layers were randomly allotted to four diet

9. Salinity regulation of copepod egg production in a large microtidal estuary
ABSTRACT Salinity is a key variable for ecological processes in estuaries. Acartia tonsa is a typical estuarine copepod whose responses to salinity have been thoroughly studied in the laboratory. However, results cannot be extrapolated to the field, and formal comparisons between lab and field responses to salinity were not attempted. Here we compare lab-bas

10. Development and morphological characterization of the immature stages of Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae)
ABSTRACT The gregarious endoparasitoid Tetrastichus giffardianus Silvestri (Hymenoptera: Eulophidae) is a natural enemy of fruit flies. This parasitoid was previously used to successfully control Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Hawaii, USA. Despite its importance in the control of fruit fly pests, little is known about the developmen

12. Performance and welfare of different genetic groups of laying hen
ABSTRACT. The objective was to evaluate the performance, egg quality, thermoregulation, body morphology and behavior of different categories of laying poultry. Two treatments with two genetic groups were used, 50 birds of the Hisex Brown strain and 50 birds of the Black Avifran chicken breed with 55 weeks, distributed in a completely randomized design with 1
