1. The influence of a light and dark cycle on the egg laying activity of Aedes aegypti (Linnaeus, 1762) (Diptera: Culicidae)
BACKGROUND The epidemiological importance of the mosquito Aedes aegypti as a vector of multiple human pathogens has generated a growing number of studies on the physiology and behaviour of its blood-feeding females. The activity of oviposition is one of the critical elements contributing to the expansion of Ae. aegypti's populations. Although there is a vas

2. Feeding behavior and productive performance of steers fed pearl millet grain-based diets containing proportions of babassu mesocarp bran
ABSTRACT The objective of this study was to evaluate the feeding behavior and feedlot productive performance of dairy-origin steers fed for 84 days ground pearl millet grain-based diets with 0, 120, 240, 360, and 480 g kg-1 of babassu mesocarp bran (BMB) and a standard diet based on ground corn. Thirty Holstein-Zebu steers with average initial body weight of

3. Effect of Forced Molting on body characteristics and post-molting egg production performance of Layers in Quetta, Pakistan
White leghorn layer (n=2740), with 85weeksof age, were submitted to forced molting by fasting for 13 days and changes in body characteristics and subsequent laying performance during second laying cycle were evaluated. Live body weight (LBW),ovary weight (OW), oviduct weight (OvW) and oviduct length (OvL) were measured before and after fasting. Post-fasting

4. Dietary fiber inclusion as an alternative to Feed Fasting to induce molting in Commercial Layers
The objective of the present experiment was to compare the performance, egg quality and organ morphometrics of commercial layers submitted to alternative forced molting methods using dietary fibers. The experimental period included the phases of molting, rest, and second laying cycle (six periods of 28 days each). In the trial, 320 commercial Isa Brown layer

5. Estimates of true amino acid digestibilities in feed ingredients using precision-fed, cecectomized roosters.
O objetivo deste trabalho foi estimar os coeficientes de digestibilidade verdadeira dos aminoacidos de oito ingredientes alternativos para alimentacao de galos cecotomizados. Vinte e sete galos Leghorne de crista inteira foram usados para estimar os coeficientes de digestibilidade verdadeira dos aminoacidos (TAAD) de oito alimentos. A alimentacao precisa (fo

6. The effects of alternative forced-molting methods on the performance and egg quality of commercial layers
This study aimed at studying alternative methods to induce molting and to compare them with the conventional forced-molting method (fasting). In the experiment, 420 70-week-old layers were used. The total experimental period was 140 days. Molting was induced during the first 28 days, when birds were submitted to the experimental treatments, and bird performa

7. Esclerose lateral amiotrofica : estudo prospectivo de parametros respiratorios / Amyotrophic lateral sclerosis : prospectivestudy on respiratory parameters
The objective of this study was to evaluate the respiratory function of patients with amyotrophic lateral sclerosis (ALS), using the parameters of spirometry, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), arterial blood gases and pulse oximetry, and monitor them during the period of 8 months. The study was crosssectional assessmen

10. Nutritional value of rice brans supplemented with phytase determined by different methodologies on birds / Valor nutricional de farelos de arroz suplementados com fitase, determinado por diferentes metodologias com aves
Most rations for birds is formulated on the basis of corn and soybean meal, feedstuffs of high cost. But, the use of non-conventional feeds will be able to make them more economical, since they do not affect negatively the performance of those animals. Five metabolism trials were conducted in the Poultry Production Sector of the Animal Science Department of

11. Values of metabolizable energy and amino acids digestible of some victuals for broilers / Valores de energia metabolizável e de aminoácidos digestíveis de alguns alimentos para aves
Two experiments were accomplished in the section of aviculture of the Department of Zootecnia of the Federal University of Viçosa, in order to evaluate the energy values and of amino acids digestible of some victuals that can be used in the formulation of rations for poultry. The first objectified the determination of the values of apparent metabolizable en
