1. Copaiba (Copaifera reticulata) oleoresin reduces voluntary alcohol intake in rats
RESUMO O óleo extraído da árvore copaíba, Copaifera reticulata, tem sido usado na medicina popular na Amazônia brasileira para diversos fins, incluindo abuso de drogas. Contudo, não há estudos avaliando o efeito da administração repetida do óleo de copaíba sobre o consumo de álcool em animais. Para avaliar esse efeito, dividimos ratos Wistar mach

2. Do live or inactive yeasts improve cattle ruminal environment?
ABSTRACT This research was conducted to investigate the effect of live and inactive sugarcane yeast on beef cattle voluntary intake, apparent digestibility of nutrients, ruminal pH, volatile fatty acids (VFA) concentrations, and ruminal ammonia. Five rumen-cannulated Nellore heifers were distributed in a 5×5 Latin square design, with five experimental perio

4. SODIUM BICARBONATE SUPPLEMENTATION IMPROVES PERFORMANCE IN ISOMETRIC FATIGUE PROTOCOL
RESUMO Introdução: A suplementação de bicarbonato de sódio (NaHCO3) tem demonstrado atenuar a fadiga e melhorar o desempenho do exercício de alta intensidade, mas os efeitos sobre a manutenção de contrações isométricas são pouco claros. Objetivo: Investigar o efeito do NaHCO3 no desempenho de indivíduos submetidos ao protocolo de fadiga em exe

5. Performance and methane emissions of Nellore steers grazing tropical pasture supplemented with lipid sources
ABSTRACT The objective of this study was to evaluate the effect of lipid sources on voluntary intake, digestibility, performance, and CH4 emission of Nellore steers grazing Brachiaria brizantha cv. Xaraés forage in the dry season. Forty-five Nellore steers with average weight of 442±34 kg were alloted into one of the five treatments: without additional fat

6. Supplementation with corn oil and palm kernel oil to grazing cows: ruminal fermentation, milk yield, and fatty acid profile
ABSTRACT The effect of supplementation with corn oil (CO) and its mixture with palm kernel oil (CO:PKO 75:25) to grazing cows on ruminal fermentation, milk yield, and its fatty acid (FA) profile was evaluated. The treatments were: one control treatment (C) without oil and two treatments with 720 g d−1/cow of CO or CO:PKO (ether extract: 22.7 g kg−1 for c

7. Concomitant stress potentiates the preference for, and consumption of, ethanol induced by chronic pre-exposure to ethanol
Ethanol abuse is linked to several acute and chronic injuries that can lead to health problems. Ethanol addiction is one of the most severe diseases linked to the abuse of this drug. Symptoms of ethanol addiction include compulsive substance intake and withdrawal syndrome. Stress exposure has an important role in addictive behavior for many drugs of abuse (i

8. Mineral mixtures from solid salt residues for lambs
The objective of this study was to evaluate water, mineral, feed and nutrient voluntary intakes, in addition to dry matter and nutrient digestibility and the nitrogen balance of lambs fed three mineral supplements. The first treatment consisted of solid salt residue (SSR) from an aquaculture tank; the second contained SSR from desalination waste; and the thi

9. Intake and digestibility of sorghum (Sorghum bicolor, L. Moench) silages with different tannin contents in sheep
The purpose of this study was to evaluate the voluntary intake and digestibility of three sorghum (Sorghum bicolor, L. Moench) hybrid silages in sheep. The hybrids used were H1 -BRS 655 (CMSXS 222 A × CMSXS 235 R), with tannin; H2 -(ATF54 A × CMSXS 235 R), without tannin; and H3 -BRS 610 (CMSXS 232 A × CMSXS 234 R), without tannin. The intake and digestib

10. Models for estimating feed intake in small ruminants
This review deals with the most relevant limits and developments of the modeling of intake of sheep and goats reared intensively and extensively. Because small ruminants are normally fed ad libitum, voluntary feed intake is crucial in feeding tactics and strategies aimed at optimal animal production. The effects of genetic, neuroendocrine, hormonal, feed and

11. Caracterização do comportamento materno e suas implicações no desenvovimento fisico,na função reprodutiva e no perfil hormonal da prole feminina de ratas UChA e UChB (consumidoras voluntárias de etanol a 10%) / Maternal care evaluation and effecta of the physical development, reproductive functions and hormonal profile of UChA UChB rats female offspring (10% v/v ethanol voluntary intake)
Estudos realizados com mães dependentes de etanol demonstraram que elas apresentam maior dificuldade em cuidar de suas crianças, quando comparadas às mães não dependentes, evidenciando um distúrbio no comportamento materno durante o período pós-natal, que corresponde ao período onde as primeiras ligações sociais do animal são formadas e o organis

12. Nutritive value of diets containing pods of faveira (Parkia platycephala Benth.) for confined finishing sheep
Performance and apparent digestibility were evaluated in sheep fed diets containing different amounts of faveira (Parkia platycephala) pods in replace to corn. Twenty crossbred Santa Inês lambs of approximately four months of age and average 21 kg were kept in individual stalls in randomized blocks and distributed according to weight. The following characte
