Abstract:
This dissertation focuses on the impact of nutrition to modulate and optimize milk production, blood metabolites and liver metabolism. Specifically, the main aim was to elucidate the effects of rumen protected choline (RPC) supplementation to lactating dairy cows on production, metabolic health and hepatic gene expression, for which two different studies were performed. The first study, a meta-analysis of the effect of RPC supplementation on milk yield (MY), nonesterified fatty acids (NEFA) and β-hydroxybutyrate (BHBA) in lactating dairy cows was performed in order to obtain an overall view

Abstract:
The main objective of this thesis was to have a deeper knowledge about the influence of feeding strategies with several natural plants extracts on pig performance and meat quality in different phases of pig production. To achieve this objective, a set of 4 studies were performed (chapter 2-6). The first study evaluated the effect of dietary supplementation with a mixture of algae plus polyphenols (AM) in lactating sow on maternal and piglets performance and sows reproductive data until the subsequent farrowing. This study showed that integration of AM in sow diet decreased the fat mobilizati

Abstract:
The interaction effects of genotype and nutrition on the performance of sows during lactation is still poorly understood; this series of experiments explored the factors contributing to breed differences in lactational performance and the development of appropriate feeding strategies. Two extreme types of sow were used in these experiments; lean pure-bred White sows (W: Large White and Landrace) and a prolific but fatter Meishan synthetic damline (M: 50% Meishan genes). M sows had higher numbers of piglets, a different feed intake curve and produced more milk with a higher fat content compared

Nutrition plays an important role in maintaining a good health status of animals as nutrients can modulate oxidative status, immune and inflammatory response.

Anthocyanins are very important nutraceuticals not only because they protect plants against biotic and abiotic stresses (Winkel-Shirley, 2002) and they seem to be involved in plant yield (Frascaroli and Landi, 1998), but also because they exert antioxidant abilities able to protect human and animal health (Virgili and Marino, 2008). Maize is able to accumulate anthocyanin in different tissues (Escribano-Bailon et al., 2004; de Pascual-Teresa et al., 2002), so that it can be considered a functional food.

O objetivo desta pesquisa foi estudar a composição químico-bromatológica sobre a variedade de cana-de-açúcar IAC86-2480 submetida a três métodos de colheita. Os tratamentos corresponderam a três métodos de colheita: colheita manual (MAN), colheita mecanizada (MEC) e colheita mecanizada seguido de rebaixamento manual (MEC+MAN). O tratamento relativo ao corte manual foi efetuado na região do colo da planta, rente ao solo, com uso de podão.No caso do corte mecanizado, foi utilizada uma colhedora de forragem regulada para altura de corte de 20 cm. O terceiro tratamento foi aquele em que as plantas

Abstract:
Gas chromatography mass spectrometry (GCMS) and inductively coupled plasma mass spectrometry (ICPMS) were evaluated for the measurement of selenium (Se) and Se stable isotope ratios. GCMS and ICPMS were found to be accurate for quantitative Se analysis in biological matrices by isotope dilution using Se-78 and Se-76 as internal standards, respectively. A higher precision was obtained for ICPMS than GCMS enabling a smaller quantity of the tracer to be administered to subjects in labelling experiments. The isotopes of choice for metabolic tracers were Se-76 when sample analysis was by GCMS and S
