Fuzzy modeling in the prediction of climate indices and productive performance of quails kept in climate chamber REA
MARQUES,JORDÂNIO I.; LOPES NETO,JOSÉ P.; LOPES,FERNANDA F. DE M.; FURTADO,DERMEVAL A.; ARAÚJO,TIAGO G. P..
ABSTRACT With the demand in the production at large-scale food, confinement of animals has become a necessity of the productive process because of the increase in production capacity and optimization of the spaces reserved for creations. In this context, the aim of this study was the development and validation of models using fuzzy logic for predicting climate indices and productive performance of European quails kept in a climatic chamber. The model developed was analyzed from two points of view; the first one took into account the prediction of climate indexes where the input variables were the temperature (°C) and relative humidity (%) of the air. In the second, related to the prediction of productive performance, the input variables were air...

ABSTRACT: The objective of this study was to evaluate the effect of replacing corn with sorghum in feed on performance, carcass yield, and composition of specialized meat cuts in quails. A total of 1200, 1-day-old female quails were raised up to 42 days of age. The completely randomized design consisted of four treatments with six replicates each and with 50 quails in each cage. Treatments consisted of four levels of sorghum replacement in the diet (0, 40, 60, and 100% sorghum). All birds were weighed to assess the weight gain. Feed conversion was calculated as the relationship between feed intake and weight gain. Mortality was reported daily and calculated at the end of each week. At 42 days, the birds were slaughtered and the carcass, thigh and...
