1. 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

2. An Outbreak of Intestinal Obstruction by Ascaridia Galli in Broilers in Minas Gerais
ABSTRACT Industrial broilers raised on helminthic medication-free feed were diagnosed with a severe disease caused by Ascaridia galli, characterized by intestinal hemorrhage and obstruction. A. galli was identified based on the morphological features of the nematode. Broilers were raised for a longer period (63 days) for weight recovery, grouped as stunted (

3. The use of Arthrospira platensis in rearing Nile tilapia (Oreochromis niloticus) in salt water
RESUMO A tilápia do Nilo (Oreochromis niloticus) é uma espécie eurialiana e em sistemas marinhos é capaz de fornecer proteína animal onde a água doce é escassa. Com isso, torna-se imprescindível o gerenciamento adequado da água para manutenção da sustentabilidade, e o uso do sistema de recirculação de água salgada seria vantajoso para o atual m

4. Typology of beef production systems according to bioeconomic efficiency in the south of Brazil
RESUMO: O objetivo deste estudo foi avaliar a eficiência bioeconômica em sistemas de produção de bovinos de corte no sul do Brasil. A pesquisa foi realizada com 33 pecuaristas que operam com sistemas de produção baseado em ciclo completo, em áreas maiores ou iguais a 900 hectares. As respostas foram classificadas em dois fatores: tecnologia (TEC) e g

5. Grapeseed Meal Used as Natural Antioxidant in High Fatty Acid Diets for Hubbard Broilers
ABSTRACT The 7-week feeding trial evaluated the effect of 2% grapeseed meal used as natural antioxidant in the diets for slow-growing Hubbard broiler chicks, aged 14 days. The chicks were weighed individually and assigned to two groups (C and E), with 40 chicks per group, housed under conditions of temperature, humidity and light regimen according to the hyb

6. Glycemic response of poultries in different feeding systems
ABSTRACT. The management of poultry feed is an important welfare promoter and the glycemic index a noninvasive evaluation. The aim was to evaluate the glycemic response of broiler breeders in restricted feeding system, and broilers receiving ad libitum feeding. Two experiments were carried out: I) 39-week-oldbroiler breeders, fed with three sources of fiber,

7. Understanding heat stress in beef cattle
ABSTRACT Thermal stress is the result of a misbalance between heat produced or gained from the environment and the amount of heat lost to the environment. The level of thermal stress can range from minor or no effect to death of vulnerable animals. Under summertime conditions, thermal stress results in hyperthermia or heat stress. Heat stress in feedlot catt

8. Technical efficiency analysis of marine shrimp farming (Litopenaeus vannamei) in biofloc and conventional systems: A case study in northeastern Brazil
Abstract Shrimp farming has a great ecological, economic, and social importance in northeastern Brazil. Although the conventional farming system is widely used, biofloc technology (BFT) system has been developed to reduce environmental impacts and optimizing the production. Thus,the present study evaluated the technical efficiency of production cycles of Lit

9. Determining the Contribution of Ventilation and Insulation of Broiler Breeding Houses in Production Performance Using Analytic Hierarchy Process (AHP)
ABSTRACT This study was conducted using Analytic Hierarchy Process (AHP) in order to rank broiler breeding farms in Zanjan province, Iran, regarding buildings, installations, and equipment to determine their effects on production factors. Data on 108 farms were collected using designed forms. This data was analyzed based on the effectiveness of each paramete

10. Live Performance, Carcass, and Bone Quality Responses of Grower and Finisher Broilers to Dietary Metabolizable Energy Levels
ABSTRACT Broiler energy nutrition has attracted attention due to its economic importance, particularly during the rearing period of 22-42 days of age. There are many evidences that broilers changed their feed intake capacity due to genetic selection, especially when good quality pellets are fed, which suggests that modern broiler strains may achieve good per

11. Performance, Carcass Traits and Economic Availability of Muscovy Ducks Fed on Different Nutritional Plans in Different Housing Densities
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

12. A model for multidimensional efficiency analysis of public hospital management
Abstract Introduction Multidimensional efficiency analysis can provide important insights into the performance of hospitals. In this paper, we propose a multidimensional model based on Data Envelopment Analysis (DEA) to investigate and compare the efficiency of public hospitals in Brazil. Methods Data from 21 public hospitals were collected from public dat
