1. SUPLEMENTAÇÃO DE SELÊNIO NA DIETA E QUALIDADE ESPERMÁTICA DO SÊMEN DE TOUROS BRANGUS
Resumo Objetivou-se avaliar a qualidade espermática do sêmen de touros suplementados com selênio (Se) na dieta. Foram utilizados 16 touros Brangus, igualmente distribuídos em grupo controle (GC) e grupo Se (GSe − 0,1mg de Se/kg de MS de dieta). O experimento teve duração de 75 dias, e os animais foram suplementados por 60 dias. Foram realizadas quatr

2. Standardization of A Sample-Processing Methodology for Stable Isotope Studies in Poultry
ABSTRACT The objective of this study was to determine if lipid extraction processes alter the isotopic value of δ13C and δ15N of tissues (pectoral muscle, thigh and liver) and eggs and if the use of anticoagulants interferes with blood and plasma δ13C and δ15N isotopic values. Samples were acquired from the same flock of birds. The 32 egg samples were ra

3. Assessment of human health risk associated with the presence of pesticides in chicken eggs
Abstract The presence of pesticides in the environment is highly toxic to environment and human health. Aim of the study was determination, quantification and assessment of associated health risk due to presence of pesticide residues in chicken eggs using high pressure liquid chromatography. HPLC method was successfully employed and validated. From collected

4. The Addition of Hatchery Liquid Waste to Dairy Manure Improves Anaerobic Digestion
ABSTRACT The objective of this study was to determine the optimal inclusion level of liquid egg hatchery waste for the anaerobic co-digestion of dairy cattle manure. A completely randomized experimental was applied, with seven treatments (liquid hatchery waste to cattle manure ratios of0: 100, 5:95, 10:90, 15:85, 20:80, 25:75 and 30:70), with five replicates

5. Rapid and Highly Sensitive Determination of Melamine in Different Food Samples by Corona Discharge Ion Mobility Spectrometry after Dispersive Liquid-Liquid Microextraction
In this work, for the first time, a highly sensitive method based on dispersive liquid-liquid microextraction coupled with positive corona discharge ion mobility spectrometry as a fast and inexpensive technique has been evaluated for the direct determination of melamine. The effective parameters influencing the microextraction efficiency, such as pH, the pro

6. In vitro photoprotective effects of Marcetia taxifolia ethanolic extract and its potential for sunscreen formulations
AbstractThe species Marcetia taxifolia (A. St.-Hil.) DC., Melastomataceae, which is endemic of the rupestrian fields of northeastern Brazil, contains a significant amount of flavonoids. In this work, the potential of the ethanolic extract of M. taxifolia as the active principle in a sunscreen photoprotection (UV-A and UV-B) formulation was investigated. The

7. Separation, Concentration and Determination of Trace Thiamphenicol in Egg, Milk and Honey Using Polyoxyethylene Lauryl Ether-Salt Aqueous Two-Phase System Coupled with High Performance Liquid Chromatography
As a pretreatment technique to trace analysis, polyoxyethylene lauryl ether (POELE10)- salt aqueous two-phase extraction system (ATPES) is coupled with high performance liquid chromatography to analyse thiamphenicol (TAP) in egg, milk and honey. The analysis of the phase behaviors of the ATPES found that the extraction efficiency and enrichment factor of TAP

8. Large scale artificial rearing of Anastrepha sp.1 aff. fraterculus (Diptera: Tephritidae) in Brazil
Some species of the genus Anastrepha (Diptera: Tephritidae) are successfully managed by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and quality

9. Infecção congênita em cabritos por Mycoplasma agalactiae
This study aimed to report three cases of contagious agalactia (CA) by Mycoplasma agalactiae in goat kids born with polyarthritis. The nanny goats belonging to two different herds presented clinical signs of CA during pregnancy and in parturition they were apparently healthy. The carpal articulations of the three goat kids, the tarsus articulation in one, an

10. Assessment of the interaction between straw size and thawing rate and its impact on in vitro quality of post-thaw goat semen
The objective of this study was to analyze interactions between different straw sizes and thawing rates on the post-thaw goat semen parameters. Twenty-one ejaculates (seven per animal) were collected from three stud bucks by using an artificial vagina. After evaluation, the semen was extended in Tris-egg yolk-glycerol and packed in 0.25 and 0.50 mL straws, f

12. Modulation of expression and activity of cytochrome P450s and alteration of praziquantel kinetics during murine schistosomiasis
In this study, we investigated the expression and activity of liver cytochrome P450s (CYPs) and praziquantel (PZQ) kinetics in mice infected with Schistosoma mansoni. Swiss Webster (SW) mice of both genders were infected (100 cercariae) on postnatal day 10 and killed on post-infection days (PIDs) 30 or 55. Non-infected mice of the same age and sex served as
