1. Performance and Egg Quality of Commercial Laying Hens Fed Diets Formulated Using Non-Linear Programming
ABSTRACT Feed formulation using linear programming consists of determining the mixture of feedstuffs required to meet pre-established animal nutritional requirements at the lowest cost. On the other hand, with the use of non-linear programming, it is possible to define nutritional requirements at the time of formulation, aiming at maximum profit. The objecti

2. Poultry by-product meal as dietary protein source for dourado, Salminus brasiliensis: an economic appraisal
ABSTRACT: The dourado, Salminus brasiliensis, a large, carnivorous, Neotropical, Characin, is highly regarded for fish farming and sport fishing alike. However, studies on the farming and husbandry of dourado are still scarce. This study evaluated the performance of dourado fed diets formulated so as to contain increasing levels of poultry by-product meal as

3. TERMINAÇÃO DE CORDEIROS, COM E SEM SUPLEMENTAÇÃO NA FASE DE CRIA, CONFINADOS OU SEMICONFINADOS EM Brachiaria brizantha DIFERIDA: PARASITISMO GASTRINTESTINAL E EFICIÊNCIA BIOECONÔMICA
Resumo Objetivou-se avaliar os efeitos da suplementação na fase de aleitamento sobre o desempenho ponderal, o grau de infecção por nematódeos gastrintestinais e a viabilidade econômica na terminação de cordeiros em confinamento ou semiconfinamento. Na fase de aleitamento, os cordeiros de seis lotes de 30 ovelhas foram pesados ao nascimento e ao desma

4. Breeding goals and economic values for Nellore cattle in a full-cycle production system
ABSTRACT. The objective of this study was to develop a bio-economic model for the estimation of economic values of economically important traits in a full-cycle beef cattle production system. The bio-economic model calculated economic values by simulating the impact of changes in the profit of the system consisting of a 1% increase in each trait of the breed

5. 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

6. Economic analysis, performance, and feed efficiency in feedlot lambs
ABSTRACT The objective of this study was to evaluate residual feed intake (RFI), residual intake and body weight gain (RIG) and their relationship with other traits of efficiency, performance, and economic analysis of sheep. Lambs (n = 102) were evaluated during 56 days and a herd consisting of 500 ewes was simulated with the mean of dry matter intake (DMI)

7. Densidad y manejo de ejes en plantas injertadas de tomate indeterminadas en invernadero
ABSTRACT Grafting in tomato is a regular production practice aimed to control vascular diseases. Even though grafted plants are more expensive, when a vigorous rootstock is used the plants can be trained using multiple leading shoots, reducing the number of plants per hectare. Seeking to reduce direct labor cost and the cost of the plants, this experiment te

8. Climatic Variation: Effects on Stress Levels, Feed Intake, and Bodyweight of Broilers
ABSTRACT Chickens tolerate a very narrow range of climatic variation, and therefore, it is essential to determine the most suitable climatic area and weather for broiler production in open-house systems. In this study, 3060 broilers were used as experimental birds to investigate the effects of seasonal differences and climatic variations on the growth perfor

9. APPLICABILITY OF NON-FEED REMOVAL PROGRAMS TO INDUCE MOLTING INSTEAD OF THE CONVENTIONAL FEED WITHDRAWAL METHOD IN BROWN LAYING HENS
ABSTRACT This study was conducted to compare the applicability of non-feed removal (NFR) programs to induce molting in brown laying hens by feedusing alfalfa meal and barley grain on molting of instead of feed withdrawal in terms of performance, egg quality and profitability. A total of 240, 75-week-old Hy-Line brown laying hens were randomly divided into th

10. Relações entre eficiência alimentar, características de carcaça e qualidade de carne de novilhos Nelore confinados / Feed efficiency and its relationships with profitability, carcass characteristics and meat quality of Nellore steers
Although Brazil has the largest commercial beef cattle herd of the world, research on genetic improvement of beef cattle for feed efficiency is incipient. Some countries have invested in studies to identify feed efficient animals and to find molecular markers associated with this characteristic. Genetic selection of efficient animals can resulting lower cost

11. Performance and economic indicators of a large scale fish farming in Mato Grosso, Brazil
Performance and economic indicators of a large scale fish farm that produces round fish, located in Mato Grosso State, Brazil, were evaluated. The 130.8 ha-water surface area was distributed in 30 ponds. Average total production costs and the following economic indicators were calculated: gross income (GI), gross margin (GM), gross margin index (GMI), profit

12. Biological and economic performance of feedlot lambs feeding on diets with different energy densities
The objective of this study was to evaluate performance, carcass dressing and gross profit margin of lambs of different genotypes finished in feedlot with diets containing two levels of energy (2.40 Mcal/kg dry matter - DM or 2.90 Mcal/kg DM). Fifty-four non-castrated lambs of the following genotypes were used: Santa Inês, F1 Dorper × Santa Inês and F1 Sa
