| ABSTRACT The present study aimed to evaluate ducks on performance, carcass traits and economic availability, fed on different phases of nutritional plans and in different housing densities. Two hundred and forty Muscovy ducks of creole lineage were used, distributed in boxes with water and food ad libitum. The experimental design was completely randomized in a factorial arrangement of 3x2 with three nutritional plans (3, 4 and 5 phases) and two housing densities (2 and 3 birds/m2) with four replicates. The ducks had weekly performance evaluations, and after 90 days, four birds in each treatment were slaughtered for evaluation of carcass traits. Differences (p<0.05) were observed on performance, carcass traits and economic analysis. The nutritional plans... |

| ABSTRACT: This study was designed to simulate productive and economic losses due to the withdrawal of antibiotic growth promoters (AGP) from pig diets. Articles that compared diets with AGP (AGP+) or without AGP (AGP–) for pigs were collected from electronic databases and the performance results were entered in a database. A meta-analysis was performed following the sequence: graphical analysis, correlation, and variance-covariance. The performance results observed in the meta-analysis, feed cost, and AGP costs were used to build equations to estimate the economic effect of withdrawing AGP. The database comprised 81 scientific articles containing 103 experiments totalizing 42,923 pigs. Avilamycin (24.7 %) was the most frequent AGP in the database, followed... |

| This study was aimed to investigate the effect of Ocimum sanctum and Tinospora crispa supplemented on growth performance, feed intake, feed efficiency and feed cost in commercial broilers. One hundred and fifty day old Arbor Acres chickens of mixed sex were randomly sampled in a completely randomized design with 5 treatments and 3 replications, ten chickens per replication. All chickens were fed by commercial diet which was supplemented with various levels of Ocimum sanctum at 1%, 1%, 0.5% and 0.5% of completed feed, respectively, and Supplemented with Tinospora crispa Treatment 1 was a control group. Treatment 2, 3, 4 and 5 were supplemented with Ocimum sanctum and Tinospora crispa at 0.4 %, 0.2%, 0.4%, and 0.2% of completed feed, respectively. The... |

| This study aimed to evaluate the increasing levels (0, 1, 2, 3 e 4%) of fish by-product meal in diets for laying hens on performance, egg quality and economic analysis. A total of 160 Dekalb White hens with 52-wk old were distributed in a completely randomized design with five treatments and four replicates of eight birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of fish by-product meal levels were determined by polynomial regression. Differences (p < 0.05) were detected for all variables of performance, in egg weight, yolk and albumen percentage, yolk and albumen height, feed cost and production cost, in which the inclusion of fish by-product meal in the diets showed better results. It can be concluded that... |
