1. INGESTIVE BEHAVIOR OF SANTA INÊS SHEEP UNDER THERMONEUTRALITY AND THERMAL STRESS UPON CONSUMPTION OF SALINE WATER
ABSTRACT The consumption of saline water in semiarid regions is a recurrent situation that can affect the ingestive behavior of small ruminants. This study evaluated the ingestive behavior of Santa Inês sheep maintained in a climatic chamber under two air temperatures -25 °C within the thermal comfort zone (TCZ) and 32 °C above the TCZ - and consuming wat

2. ARTIFICIAL NEURAL NETWORKS FOR PREDICTION OF PHYSIOLOGICAL AND PRODUCTIVE VARIABLES OF BROILERS
ABSTRACT Due to a number of factors involving the thermal environment of a broiler cutting installation and its interaction with the physiological and productive responses of birds, artificial intelligence has been shown to be an interesting methodology to assist in the decision-making process. For this reason, the main aim of this work was to develop an art

3. Analysis of NH3-N Slow Release systems for fiber digestibility of low-quality forage: in vitro approach
ABSTRACT: Urea is a common non-protein supplement used in ruminant feed; however, excessive consumption may lead to poisoning by NH3. Although the slow release of urea into the rumen has shown to be an essential aspect for ruminant feed, to date only a few studies have addressed this matter. In this study we examined the influence of five different NH3-N slo

4. ENERGY AND EXERGETIC EVALUATION OF THE MULTICOMPONENT SEPARATION OF PETROCHEMICAL NAPHTHA IN FALLING FILM DISTILLATION COLUMNS
Abstract Multicomponent separation of synthetic petrochemical naphtha (hexane, cyclohexane, toluene and xylene) was carried out in a falling film distillation sequence with heat supply using a vapor chamber (thermosyphon). Tests were carried out by varying feed flow rate and temperatures of the feed and the vapor chamber in two ways of heat supply: isotherma

5. Experimental poisoning by Crotalaria lanceolata and Crotalaria pallida seeds in broilers
RESUMO: Crotalaria lanceolata E. Mey. e Crotalaria pallida Aiton. são leguminosas da família Fabaceae presentes na maioria do território brasileiro. Inicialmente foram utilizadas como adubação verde e devido sua fácil disseminação são consideradas invasoras de culturas. Através da colheita mecanizada da soja e milho pode ocorrer a contaminação de

7. Probiotic Administration Increases Mandibular Bone Mineral Density on Rats Exposed to Cigarette Smoke Inhalation
Resumo O tabagismo é um dos principais fatores de risco para a doença periodontal, aumentando sua prevalência e gravidade. Os probióticos surgiram como uma alternativa para a prevenção e tratamento de muitas doenças, uma vez que podem modular a resposta imune do hospedeiro e promover a modificação do microbioma. Dessa forma, o objetivo do presente e

9. Multinutritional blocks as a food strategy to optimize the use of concentrate for lactating goats
ABSTRACT. The objective of this study was to evaluate the use of multinutritional blocks (BMs) associated with the concentrate content in the diet of lactating goats and their effects on milk production and economic viability. Eight goats Parda Alpina, multiparas were distributed in two Latin squares (4x4). The experiment consisted of four treatments (0.971,

10. Energy budgets for juvenile Pacific whiteleg shrimp Litopenaeus vannamei fed different diets
Abstract Energy budgets for juvenile Pacific whiteleg shrimp, Litopenaeus vannamei (1.7-4.0 g ) fed with different diets were assessed. The energy partitioning between growth, respiration, ammonia excretion, feces and exuvia was calculated to estimate for total food energy intake. Shrimp oxygen consumption and ammonia excretion were quantified in sealed cham

11. Determination of methanol residues in crude glycerol for animal feed by gas chromatography
ABSTRACT: Crude glycerol is a major by-product of biodiesel production and is an economical additive feed for ruminants. However, residual methanol in crude glycerol can be harmful to animal health. Several methods exist for quantifying methanol residues in biodiesel, yet few have been described that identify the methanol level in crude glycerol. We propose
