1. Development and Validation of a Rapid and Reliable HPLC-FLD Method for the Quantification of Ciprofloxacin and Enrofloxacin Residues in Zea mays
The accumulation of antibiotics by plants is a currently concern associated to yield reduction and transference of antibiotic residues along the food web. Maize is a staple food in many parts of the world; it is also considered an important ingredient in animal nutrition. Considering the lack of validated analytical methods for the analysis of ciprofloxacin

2. 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

3. Predicting post-absorptive protein and amino acid metabolism
ABSTRACT Sustainable production of adequate quantities of food to support a growing human population is a worldwide goal. Under current feeding conditions in the United States, dairy cattle convert dietary nitrogen to milk nitrogen with 25% efficiency. The remaining 75% is excreted, which contributes to air and water quality problems and reduces economic per

4. Application of a precision nutrition tool for growing and finishing pigs
ABSTRACT The objective of this study was to evaluate a growth model applied to adjust nutritional programs for growing and finishing pigs, in a commercial production context. The phase I (calibration) was conducted in a commercial pig production unit. The data were collected from a nutritional program, a feed program, and an animal profile. In experimental p

5. Accuracy and reliability of a videogrammetry system in the analysis of displacement of Wistar rats
Abstract Aims The behavior of laboratory animals has been studied through displacement, with different objectives by researchers. Methods Although different methods have already been used in the tracking of laboratory animals, manual tracking mode videogrammetry for 2D analysis of displacement has not been observed in animal studies. The aim of this study

6. Use of dual-energy x-ray absorptiometry in non-ruminant nutrition research
ABSTRACT Precise body composition measurements are essential in animal nutrition studies because the impact of treatments is evaluated based on changes in body weight and composition. Various indirect techniques for animal compositional evaluation have been developed and evaluated for applicability in animal nutrition studies. A fast, accurate, minimally inv

7. Determination of Moxidectin in Serum by Liquid Chromatography-Tandem Mass Spectrometry and Its Application in Pharmacokinetic Study in Lambs
The widespread use of moxidectin (MOX), a parasiticide used in the sheep breeding, has induced the parasite resistance in Brazilian farms. As a consequence, the farmers often increase the dose and frequency of drug utilization, and disregards safety of meat or milk. In order to establish adequate therapeutic treatment it is necessary to know the pharmacokine

8. Estudo da etiologia das principais bactérias isoladas de mastite bovina em rebanhos leiteiros de propriedades rurais de Goiás / Etiology study of the main bacteria isolated from bovine mastitis in dairy cattle farms in the state of Goias
The bovine mastitis consists of an inflammation of the mammary gland, with acute to chronic evolution, which occurs when an infectious agent attacks the mammary gland. It is characterized by physical, chemical and sensory alterations of the milk, caused by microorganisms that invade the mammary gland and cause pathological changes in the glandular tissue. Ma

9. Evaluation of mathematical models to describe growth of grazing young bulls
The objective of this study was to evaluate the use of different mathematical models to describe growth of grazing beef cattle. Data of 20 Nellore bulls with initial weight of 129±28.1 kg and final weight of 405±62.0 kg were used. The animals were randomly divided into four plots and placed on B. decumbens Stapf pastures. Three plots received concentrate s

10. Desenvolvimento de métodos alternativos para a determinação dos íons metálicos sódio, potássio, cálcio e magnésio em amostras de biodiesel / Development of alternative methods for the determination of sodium, potassium, calcium and magnesium ions in samples of biodiesel
In this work reports two alternative methods for the quantitation of metallic ions (Na, K, Mg e Ca) in biodiesel samples. The proposed methods were applied to biodiesel that were synthesized from different vegetable oils and also animal fat. The proposed method uses water extraction, heating and ultrasound. The quantitation of the ions was performed using io

12. Identificação de bovinos através de reconhecimento de padrões do espelho nasal utilizando redes neurais artificiais / Identification of bovines through recognition of images patterns of the muzzle using artificial neural nets
Artificial Neural Networks (ANN) are mathematical models associated with artificial intelligence that can learn and generalize information, therefore they can be used as images classifiers. This paper aims to analyze the cattle muzzle in order to prove that it is a unique and permanent characteristic of the animal thus, being used as its unique identificatio
