13. Evaluation of iron bioavailability in a mixture of cereals, seeds, and grains ("Human Ration")
Iron bioavailability was evaluated in three mixtures of cereals, seeds, and grains ("Human Ration"): light, regular, and homemade provided to rats. The animals received an iron depletion diet for 21 days, followed by a repletion diet containing 12 mg·kg-1 of iron for 14 days. The hemoglobin regeneration efficiency and the relative biological value did not d

14. Concentration, characterization and application of lipases from Sporidiobolus pararoseus strain
Lipases produced by a newly isolated Sporidiobolus pararoseus strain have potential catalytic ability for esterification reactions. After production, the enzymatic extracts (conventional crude and precipitated, 'CC' and 'CP', and industrial crude and precipitated, 'IC' e 'IP') were partially characterized. The enzymes presented, in general, higher specificit

15. In situ α-alumina hydrophobization dynamics at acid pH: effectiveness limitations of short-chain amphiphilic molecules
The present work highlights that α-alumina hydrophobicity (attained by the in situ modification of its surface properties with water soluble organic monoacids) cannot be increased by using molecules with low acidity (pKa) values due to the alumina zeta potential profile at pHs below approximately 4. In order to certify this statement, the effects of short-c

16. Use of defatted flaxseed meal reduces precancerous colon lesions in C57BL/6 mice
PURPOSE: To investigate the hemopreventive effect of defatted flaxseed meal in C57BL/6 mice after induction of precancerous colon lesions with 1.2-dimethylhydrazine (DMH). METHODS: Thirty-six 12-week-old C57BL/6 mice were divided into three treatment groups(n=12 in each group): (1) diet with 10% defatted flaxseed meal; (2) diet with defatted flaxseed meal an

17. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory

18. Estudo químico, análise do óleo essencial e avaliação das atividades antioxidante e antibacteriana do Marmelhinho [Cordiera sessilis (Vell.) Kuntze (Rubiaceae)]
In this work was carried out chemical analysis, identification of volatile components, the determination of antioxidant activity and antibacterial activity of wood, bark and leaves of Cordiera sessilis (Vell) Kuntze, known as marmelinho. This study is justified because the analysis of chemical species Cordiera sessilis (Vell) Kuntze had not been studied so f

19. Produção, composição do leite e desempenho reprodutivo de ovelhas Santa Inês alimentadas com rações contendo óleo de canola ou linhaça / Milk yield, milk composition and reproductive performance of Santa Inês ewes fed diets containing canola or linseed oil
The objective in this study was to evaluate the effect of the addition of canola oil (CO) or linseed oil (LO) on milk production and composition and reproductive performance of Santa Inês ewes. In the experiment I, 33 Santa Inês ewes were fed diets containing 50% of roughage (Cynodon dactylon hay). Experimental diets included a control (no oil) and two rem

20. Intake, nutrient apparent digestibility and ruminal constituents of sheep fed diets with canola, sunflower or castor oils
The objective in this experiment was to determine the effects of feeding diets with canola, sunflower or castor oils on intake, nutrient apparent digestibility and ruminal constituents of crossbred Dorper × Santa Inês sheep. Four rumen-cannulated animals of 90.2±11.4 kg average body weight were assigned to a 4 × 4 latin square. Animals remained individua

22. Emprego dos ácidos graxos de cadeia curta na colite de derivação fecal : estudo em ratos Wistar
Colite de derivação fecal (CD) é um processo inflamatório crônico que acomete o segmento intestinal desfuncionalizado, após a confecção de colostomia. Postula-se que a deficiência nutricional do epitélio colônico pela ausência de ácidos graxos de cadeia curta (AGCC) seja um dos fatores responsáveis pelo surgimento da CD e que o emprego deles po

23. Caracterização do perfil de ácidos graxos em leite de cabra por diferentes métodos de extração de gordura ou por metilação direta / Characterization of fatty acids profile in goat milk using different fat extraction methods or by direct methylation
The objective of this research was to characterize the profile of fatty acids in goat milk by using four different methods of extraction of fat milk and a method of direct methylation for further analysis by gas chromatography. Samples were obtained from the storage tank of the caprine production systems of the Department of Animal Science at the Universidad

24. Composition and fatty acid profile of milk from cows on pasture subjected to licuri oil supplement
The objective of this study was to determine the best level of oil licuri concentrate on dairy cows. The best level was determined through an analysis of the milk's chemical composition and fatty acid profile. Sixteen lactating cows from the Holstein × Zebu cross breed kept on Tanzania grass pastures were divided into four 4 × 4 Latin squares, which were f
