2. Effects of antibiotic growth promoters mixed with mineral supplement on growth performance, ingestive behavior, and mineral intake of grazing bulls
ABSTRACT The objective was to evaluate the addition of antibiotic growth promoters to free-choice mineral supplement on ingestive behavior, mineral intake, and growth performance of grazing bulls. Sixty Nellore bulls [initial body weight (BW) of 219±17.8 kg and 15±2 months of age] were divided in 12 marandu grass paddocks. The treatments were: mineral supp

4. Evaluation of vitamin D plasma levels after mild exposure to the sun with photoprotection
Abstract: Background: Most of the organism’s vitamin D (VD) is obtained through the cutaneous synthesis after exposure to the sun’s UVB radiation. Sunscreens are indicated for the prevention of actinic damage to the skin, however, there are few clinical trials assessing the synthesis of cutaneous VD in real-life situations of sun exposure with ordinary

5. Validation of single measurement of 12-hour urine excretion for estimation of sodium and potassium intake. A longitudinal study
ABSTRACT BACKGROUND: Evaluation of sodium and potassium intake can be carried out using different methods. Biological markers are able to capture intra and inter-individual variability and are used as separate measurements of consumption. The aim of this study was to test the validity of a single measurement of urinary sodium and potassium excretion as rep

6. Mineral composition, nutritional properties, total phenolics and flavonoids compounds of the atemoya fruit (Annona squamosa L. x Annona cherimola Mill.) and evaluation using multivariate analysis techniques
ABSTRACT The atemoya is a hybrid fruit obtained by crossing of cherimoya (Annona cherimola Mill.) with sweet sop (Annona squamosa L.). The information about chemical composition of atemoya is scarce. The mineral composition was evaluated employing Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) and the centesimal composition and the physic

7. Effects of water ingestion throughout exercise and recovery on cardiac autonomic modulation during and after exercise
Abstract Purpose: To analyze the effects of water intake on heart rate variability (HRV) during and after exercise. Methods: Thirty-one young males performed three different procedures: I) a maximal exercise test to determine the load for the protocols; II) the control protocol (CP); III) the experimental protocol (EP). The protocols comprised 10 minutes at

8. Intake and digestibility of silages containing pineapple pulp and coast-cross hay with or without urea and markers recovery in sheep
ABSTRACT The objective of this study was to evaluate the intake and digestibility of silages containing pineapple pulp and coast-cross hay, with or without addition of urea, and the recovery of the markers chromium oxide (Cr2O3), indigestible neutral detergent fiber (iNDF), indigestible acid detergent fiber (iADF), and indigestible dry matter (iDM), in a dig

9. Evaluación de menús ofertados em comedores escolares: comparación entre colegios públicos, privados y concertados
ABSTRACT Objective: To evaluate menus offered in public, private and charter schools in the city of Seville (Spain) for different groups of school children. Methods: A total of 86 schools were evaluated, including public, private and charter schools, which represented every district of the city. Four schools possessed their own kitchen, while the others ha

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. Investigação das alterações do consumo de alimento palatável induzidas por trauma precoce em ratas fêmeas
Introduction: Chronic stress in adulthood increases anxiety and prones the individuals to use palatable foods as ¿comfort foods¿, which seems to be mediated by an altered functioning of the hypothalamus-pituitary-adrenal axis (HPA). We aimed at verifying if early life stress also affects anxiety, feeding behavior and stress responses in adult female rats.

12. Variabilidade do ambiente térmico em galpão para frangos de corte e sua influência nas respostas fisiológicas e comportamento das aves / Variability of thermal environment in barn for broilers and its influence on physiological responses and behavior or birds
The experiment was conducted in a barn with 21,000 Cobb male broilers, in order to characterize the variability of the thermal environment in a broiler barn and verify if the physiological responses and behavior are influenced by it. The treatments consisted of five 25 m-long sections (S1, S2, S3, S4 and S5) along the hall, set in ascending order from the ai
