This book was released on 2019 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transition from pregnancy to lactation is a time of great metabolic adaptations for the dairy cow. Dry matter intake decreases, yet demand for nutrients increase vastly with the onset of milk production resulting in negative energy balance. Cows must mobilize body tissues to increase energy for the body while sparing glucose for the mammary gland. Due to this increased metabolic demand and negative energy balance, cows often end up in a state of metabolic dysfunction which can have disastrous consequences. Nutritional strategies can help increase glucose precursors while decreasing body tissue mobilization that is linked to increased risk of disease. Previous research is mixed on the impacts of high starch to increase glucose precursors to the cow immediately postpartum, likely due to an increased risk for subacute ruminal acidosis that can result in metabolic dysfunction and inflammation. Feeding strategies which utilize high starch while also including higher fiber to promote rumen health have not been conducted. The objectives of this dissertation were to: 1) investigate interplay of fiber fractions in high starch postpartum dairy cow diets on performance, hepatic metabolism and energy balance, 2) examine interplay of inflammation, hepatic metabolism, energy metabolites, and metabolic hormones in the postpartum period, and 3) investigate opportunities to combine use of a higher digestibility corn silage with monensin to optimize production and health in the periparturient period. Increased fiber in the postpartum diet can limit intake in early lactation, resulting in negatively altered metabolism and production. As intake restrictions were eased by feeding a more fermentable diet, cows were able to recover intake, production, and energy metabolites in a matter of days to match cows that were not limited in intake early postpartum. Increased fiber in diets that may pose a higher risk of subacute ruminal acidosis may still be warranted, though further research on fiber levels and fractions is needed. Correlations between improved hepatic metabolism and metabolic hormones indicative of energy balance were positive, though correlations between markers of improved hepatic metabolism and inflammation were negative. Cows fed corn silage with higher digestibility and monensin, which increases glucose precursors, showed a possible synergistic effect on milk production. Using either strategy alone increased energy status, improved metabolism and health status, however a combination of both strategies decreased milk components, indicating they might negatively alter the rumen environment and milk fat synthesis.

Download or read book Energy Metabolism in Farm Animals written by M.W. Verstegen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal production systems have changed dramatically over the last two decades. Knowledge of energy metabolism and environmental physio logy has increased as appears from many textbooks on these disciplines. The contents of the symposia on energy metabolism of farm animals show this and they have initially focussed on feed evaluation and later on com parative aspects of energy metabolism. They show part of the progress being made. Application of knowledge of energy metabolism for animals has a long history since Lavoisier. In addition to this, studies about the environ mental requirements of animals have shown that we are still far from ac curate assessment of these requirements in terms of nutrients and ener gy. I n model studies on energy metabolism researchers have recognized the interaction between the environment and the energy requirements of animals. Estimation of energy requirements has been done in physiolo gical, physical and behavioural studies. The impact of conditions as en countered by animals in various production systems has been approached from different viewpoints related to these different disciplines. In addi tion, various kinds of infections (bacterial, parasitic: subclinical, clini cal) have been evaluated only recently with regard to their effect on pro tein and/or energy metabolism and thus on production. People working in the field of feed evaluation have defined how che mical and physical properties of nutrition infiuence energy to be derived for maintenance and production.

Book Synopsis Techniques in Free Radical Research by : A.T. Diplock
Download or read book Techniques in Free Radical Research written by A.T. Diplock and published by Elsevier. This book was released on 1991-12-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free radical species are generally short-lived due to their high reactivity and thus direct measurement and identification are often impossible. ESR is the only technique which has the potential for direct detection of radicals but in biological systems even these must be trapped by a spin-trapping agent. Thus most investigations involve recognition of indicators of the presence of radicals in vivo or "FOOTPRINTS" of radical-mediated damage. Techniques in Free Radical Research assembles and critically assesses the most relevant and reliable experimental approaches used towards the measurement of radicals and radical-mediated damage in chemical systems, in cells and in tissues under the following six headings: a) Footprints of DNA damage, b) Footprints of protein damage, c) Footprints of lipid peroxidation, d) Footprints of antioxidant consumption, e) Footprints via indirect radical assays, and f) Footprints via the availability of transition metal complexes.

Book Synopsis Nutritional Implications for Oxidative Status, Immune Function, and Energy Metabolism in Transition Dairy Cows and Relationships with Postpartum Performance and Endometritis by : Takashi Yasui

This book was released on 2013 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Factors associated with a failure to adapt metabolic and physiological regulation during the transition period include oxidative stress, metabolic disorders, and imbalanced energy status. Those factors are not only correlated to each other, but also related to low performance and immune suppression, which leads to development of periparturient-related diseases such as cytological endometritis (CE). The objectives of this work were to investigate the: 1) effect of source of trace minerals on production, oxidative metabolism, and the incidence of CE; 2) effect of chromium propionate (Cr-Pro) supplementation on production, metabolism, and the incidence of CE; 3) effect of supplemental monensin and varying postpartum fermentable starch level on the incidence of CE and related immune functions; and 4) association of CE with energy metabolism and inflammation. The first experiment found that, compared to inorganic or organic sources, supplemental hydroxy trace minerals (HTM), a recently available source of trace minerals, improved aspects of milk production, modulated plasma indices of oxidative balance, and reduced plasma haptoglobin levels immediately after parturition, suggesting that HTM are more bioavailable and can affect the body system related to production, oxidative metabolism, and inflammatory responses. In experiment two, feeding Cr-Pro resulted in improved prepartum dry matter intake in addition to reduced prepartum plasma non-esterified fatty acid (NEFA), and decreased incidence of CE along with increased uterine neutrophil influx immediately after parturition. This implies that Cr-Pro can improve periparturient energy metabolism and uterine immunity. The third experiment revealed that innate immune responses were improved during the early postpartum period in cows fed high starch diets for 3 weeks after parturition, and during early lactation in cows fed monensin. Finally, analyses conducted indicated that negative energy balance during the first 3 weeks after parturition was a critical factor to develop CE because cows with CE had higher area under the curve of plasma NEFA and beta-hydroxybutyric acid, and lower calculated energy balance during that period compared to cows without CE. The findings obtained from this work give practical approaches to optimize overall performance in transition dairy cows and provide partial mechanisms for how oxidative status, metabolism, and energy balance interrelate.
