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. Economic values for milk production and quality traits in south and southeast regions of Brazil
The objective of this study was to calculate economic values for milk (MY), protein (PY) and fat productions (FY) and somatic cell count (SCC) which could be used to compose an economic index to rank animals involved in an international genetic evaluation program of Holstein cattle used in the commercial dairy population in Brazil. The main milk production s

3. 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

4. Efeito de variáveis ambientais na implantação do sistema de inseminação artificial no Pantanal.
A pecuária de corte é a principal atividade econômica desenvolvida na planície Pantaneira. A implantação da inseminação artificial é indispensável para o aprimoramento da bovinocultura de corte, principalmente, quando se quer estabelecer um programa de melhoramento genético animal, com objetivo de alcançar maior produtividade. The beef cattle is

5. Precipitation forecast aided by weather radar for early warning system of urban floods / Previsão de chuva com auxílio de radar de tempo visando a um sistema de alerta antecipado de cheias em áreas urbanas
To reduce human and material losses during floods it is feasible to concisely study the rainfall forecast as the main part of an early warning system. The use of weather radar information, when linked to physically-based forecast models, can contribute for monitoring and forecasting of intense rainfall episodes. Thus, the rainfall forecast, based on using of

6. Expressão heteróloga do gene Hxyn2 do fungo Humicola grisea var. thermoidea em Pichia pastoris: Produção e purificação da enzima HXYN2r e aplicação em testes de panificação / Heterologous expression of the gene Hxyn2 fungus Humicola grisea var. thermoidea in Pichia pastoris: production and purification of the enzyme HXYN2r testing and application in bakery
Endoxylanases are the main group of enzymes involved in the hydrolysis of xylan. This enzymes have application in industrial proposes, like as drink, food, feed, clothes industries and for bleaching cellulose paper pulps. In bread making the xylanases have been used to improve processing and product quality of loaf, leading soft dough and loaf with larger vo

7. Modelagem e otimizaÃÃo do problema do caixeiro viajante com restriÃÃes de tempo, distÃncia e confiabilidade via algoritmos genÃticos
In this work, we propose a methodology based on the Travelling Salesman Problem, to model logistic problems. The objective of this work, in particular, is to make the Prize-Collecting Travelling Salesman Problem more coherent with the reality of the logistic context, taking into account the operational capacity of the organization and market constraints. For

8. Eficiência produtiva e econômica, características da carcaça e qualidade da carne de bovinos mestiços confinados e abatidos com diferentes pesos corporais / Productive and economical efficiency, carcass traits and meat quality of confined crossbred beef cattle and slaughtered with different body weights
The objective in this trial was to assess the bionutritional efficiency (chapter I), economicity of the finishing phase on feedlot (chapter II), quantitative and physical-chemical features of carcass (chapter III), and qualitative traits of meat (chapter IV) from crossbred F1 Red Angus x Nellore ( RA N) and F1 Blond DAquitaine x Nellore ( BA N) young bulls s

10. MicropropagaÃÃo e duplicaÃÃo cromossÃmica de hÃbridos triplÃides de capim-elefante e milheto / MicropropagaÃÃo e DuplicaÃÃo CromossÃmica de HÃbridos TriplÃides de Capim-elefante &Milheto.
Interspecific triploid (3x) hybrids, obtained through the combination of elefant-grass (2n = 4x = 28) with pearl milet (2n = 2x = 14) can overcome their ancestors in production and forage quality. Therefore, they are an alternative to obtain superior cultivars, contributing to increase the production and profit in milk production. However, the greatest limit

11. Computing simulation in plant breeding. / SimulaÃÃo computacional no melhoramento genÃtico de plantas
The objective of this study was to analyse three situations where the computing simulation could be useful in a plant breeding program: to get information about the number of families that must be handled to have more success in breeding. To verify if only the coefficient of variation is enough to discard experiments of Cultivation and Use Value, and to dete

12. Estimation of economic values for component traits of selection indexes in beef cattle. / Estimação de valores econômicos para características componentes de índices de seleção em bovinos de corte.
The objective of the present study was to estimate economic values for component of selection indexes in beef cattle herds during suckling phase. Analyzed productive data was simulated and representative of production systems assisted by breeding program. Values of costs and incomes were collected from companies related to the economical study of national ca
