ABSTRACT The objective of this study was to evaluate the oxidative stability of cashew nut meal (CNM) at 180 days of storage and the effects of its use in the feed of meat quails. A total of 280 animals at seven days of age, of both sexes, were distributed in a completely randomized design with five treatments, in a 2 × 2 + 1 factorial arrangement, and seven replicates of eight birds each. The treatments were a control diet without CNM and diets containing levels of 12.5 or 25% of new CNM (NCNM) or stored for 180 days (SCNM). The lipid oxidation of the brans was evaluated by determining the acidity index and peroxide index. The parameters evaluated were the quail performance, metabolizable coefficients and energy of diets, carcass characteristics, relative... |

ABSTRACT The intestinal health of piglets depends on the balance between diet, microflora and mucosal integrity. Disruption of this balance can compromise the digestive functions, leading to diarrhoeal frame and decline in performance of piglets. However, the level and type of fibre can limit digestive disorders. Thirty newly weaned piglets were used to evaluate the levels of neutral detergent fibre (NDF) in diets regarding performance, pH, viscosity and concentration of short chain fatty acids of digestive contents, gastrointestinal transit time, morphology of the intestinal mucosa, weights of organs and occurrence of diarrhoea. NDF level had quadratic effect on weight gain and feed conversion ratio of piglets, estimating best results at the level of... |

Feeding management of laying hens has been focused on the direct influence of nutrient intake on weight gain, especially at growing phase. This study evaluates nutrient digestibility, performance, development of the digestive tract, body composition, and bone quality of two strains of laying hens fed with different levels of neutral detergent fiber (NDF) during the growing phase from the 7th to the 12th week of age. A total of 1,296 birds were distributed in a completely randomized design in a 2 x 3 factorial arrangement (two strains x three levels of NDF) with four replicates of 54 birds per treatment. Semi-heavy (Hy Line Brown) and light-strain (Lohman LSL) pullets were allotted to dietary treatments consisting of 14.50, 16.50, and 18.50% NDF. An... |
