FUZZY MODEL FOR PREDICTING CLOACAL TEMPERATURE OF BROILER CHICKENS UNDER THERMAL STRESS
Provedor de dados: 70
Autores: Abreu,Lucas H. P.; Yanagi Junior,Tadayuki; Campos,Alessandro T.; Lourençoni,Dian; Bahuti,Marcelo.
ABSTRACT Broiler chickens submitted to different intensities and durations of thermal stress are subject to variation in cloacal temperature and, consequently, to a decrease in performance. Given the complexity of these interactions, artificial intelligence is a useful methodology for decision-making. Thus, this study aimed to assess and predict, by means of a fuzzy model, the cloacal temperature of broiler chickens submitted to thermal stress in the second week of life, with varying durations and intensities, in climatized wind tunnels. Mamdani's inference and defuzzification methods by means of the center of gravity were used. One hundred and twenty rules were elaborated. The developed fuzzy model was used to predict the cloacal temperature of broiler...

Qualidade de sementes crioulas de feijão-de corda Vigna unguiculata L. Walp.) em feira de agrobiodiversidade.
Provedor de dados: 14
Autores: DANTAS, B. F.; LIMA, P. H. C.
O feijão-de-corda é uma importante cultura para a agricultura familiar. Variedades crioulas são aquelas cujas sementes foram produzidas, selecionadas e melhoradas pelos próprios agricultores. Sementes dessas variedades geralmente são intercambiadas entre as famílias produtoras, por meio de doações, trocas e vendas em feiras da agrobiodiversidade ou dentro das comunidades. A qualidade das sementes crioulas é essencial para o desenvolvimento inicial da lavoura e sua produtividade. Assim, este trabalho teve como objetivo a avaliação da qualidade de sementes crioulas de feijão- de-corda trocadas/vendidas em uma feira da agrobiodiversidade. Foram obtidas 28 amostras de sementes, que foram avaliadas quanto a parâmetros de qualidade fisiológica das sementes...

Yield, berry quality and physiological response of grapevine to foliar humic acid application
Provedor de dados: 53
Autores: Popescu,Gheorghe Cristian; Popescu,Monica.
ABSTRACT Environmentally friendly grape growing is an important objective of modern viticulture. The aim of the study was to examine the response of two grapevine Vitis vinifera L. cultivars to humic acids (HA) foliar application as biostimulant in order to provide sustainable viticultural practices for farmers. The experiment was carried out under field conditions and repeated in two consecutive years. In order to evaluate the effect of humic acids application, the grapevines were treated with three concentrations: 30 ml.L-1 (HAT1), 40 ml∙L-1 (HAT2) and 50 ml∙L-1 (HAT3). The grapevines were represented by two grape varieties: cv. Feteasca Regala (cv. FR) and cv. Riesling Italian (cv. RI). Foliar sprays with humic acid derived from vermicompost at a...

Stress is one of the major obstacles in frog culture and can be caused by factors such as inappropriate farming systems; inadequate management among other situations. The objective of the present study was to assess the hemogram, erythrogram and leukogram of bullfrogs (L. catesbeianus) when exposed to stress caused by different types of management: density and handling (manipulation), developed in the laboratory and repeated in the field for the appropriate comparisons in a experimental period of 30 days. The density experiment was conducted with four treatments: 70 animals m-2 (D70); 100 animals m-2 (D100), Control; 150 animals m-2 (D150) and 200 animals m-2 (D200), with 10, 14, 21 and 28 animals/box in the laboratory, respectively. Each treatment was...
