Book Description
Advances in Conjugated Linoleic Acid Research, Volume 2 is the second book in a series devoted entirely to conjugated linoleic acid. This book has updated information on the analysis, biochemistry and applications of conjugated fatty acids in an attempt to make Volume 2, in conjunction with Volume 1 (published in 1999), the most comprehensive, up-to-date sources of CLA-related information available today. Both scientific and commercial views are presented, with the same data sometimes interpreted differently.

Book Description
We hypothesized that supplementation of dietary conjugated linoleic acid (CLA) and arginine singly or in combination would increase animal performance and meat quality by decreasing adiposity and increasing lean mass in growing-finishing pigs. Sixteen pigs (80 kg) were assigned to four treatments in a 2 x 2 factorial design, differing in dietary fatty acid and amino acid composition [control: 2.05% alanine (isonitrogenous control) plus 1% canola oil (lipid control); CLA: 2.05% alanine + 1% CLA; arginine: 1% arginine + 1% canola oil; arginine + CLA: 1% arginine + 1 CLA]. Preliminary tests indicated that up to 2% arginine was acceptable without interfering with lysine absorption. Pigs were allowed to feed free choice until reaching 110 kg. There were no significant differences across treatments in feed intake, weight gain, or feed efficiency. CLA tended to decrease carcass length (P = 0.06), whereas backfat thickness tended to be greater in pigs supplemented with arginine (P = 0.08). Arginine decreased muscle pH at 45 min postmortem (P = 0.001) and tended to increase lightness of muscle at 24 h postmortem (P = 0.07). CLA supplementation increased the concentrations of trans-isomers of 18:1 (P = 0.001) and SFA (P = 0.01) in s.c. and r.p. adipose tissue. CLA supplementation increased palmitate incorporation into total lipids in longissimus muscle (P = 0.01). Glucose oxidation to CO2 in r.p. and s.c. adipose tissue were greater in pigs supplemented with CLA in the absence or presence of arginine (P = 0.03 and P = 0.04, respectively). The volume of s.c. adipocytes in s.c. and r.p. adipose tissues was greater in pigs supplemented with CLA, arginine, or CLA plus arginine than in control pigs (P = 0.001). Neither CLA nor arginine affected the expression of PGC-1[alpha], AMPK, mTOR, CPT-1A, FAS, or SCD (P> 0.05) in any tissues. We conclude that there was no significant interaction between arginine and CLA. Supplementary CLA or arginine to finishing-growing pigs did not modulate growth performance and did not reduce adiposity. CLA increased intramuscular fat content without deteriorating meat quality traits and increased saturated fatty acids and substrate oxidation in adipose tissues. In the presence of 1% of canola oil or CLA in the diet, arginine has the potential to deteriorate meat quality by reducing early postmortem pH and by increasing carcass fatness.

Book Description
Conjugated linoleic acids (CLA) isomers of linoleic acid – a compound derived from meat and dairy products. Attention was first drawn to their potential anti-carcinogen properties in the 1980’s; since then further health benefits have been reported, and applications in the glue and paint industries as a renewable resource have been explored. This comprehensive book presents an overview of the background and research into CLA and examines each of their applications in the context of the chemistry surrounding them and CLA-enriched oils. The biosynthesis of CLA is presented, with a discussion on how animal husbandry could promote CLA production. Other chapters examine the current strategies for their synthesis using bespoke catalysts and enzymes. Readers from academia and industry will find the layout of the book highly accessible, with sections for each application. The editors are both active researchers in the field, and have brought together a wealth of expertise from across the globe, presenting a comprehensive guide to this valuable group of compounds and their potential applications.

Book Description
Dairy foods have huge potential concerning functional foods. Therefore, there is a tremendous amount of interest in value-added milk products and the identification of components in food which have health benefits. This book provides an overview of these derived components and their diverse activities including: the stimulation of beneficial microflora, alerting the immune system to the presence of potential pathogens and allergens, binding and eliminating toxins, etc.

Book Description
Polyunsaturated Fatty Acid Metabolism explores a number of major roles of PUFA in the body, including its role as a component of cell membranes and how it provides substrates for the synthesis of lipid second messengers. Recent studies are unraveling the effect of interactions between diet and endocrine factors and genetic and epigenetic variation on the regulation of PUFA biosynthesis in animals. Together, these recent findings provide novel insights into the impact of differences in PUFA supply on health. This book captures these findings in a manner that marks the state-of-the-art, placing them in the wider context of PUFA metabolism and nutritional science. Users will find a comprehensive discussion on the topic that presents the contributions of leading researchers who combine their knowledge to create a cohesive academic resource for researchers, those involved in production, and health policymakers. - Provides a comprehensive view of polyunsaturated fatty acid metabolism - Describes underlying metabolism on lipids that include polyunsaturated fatty acids - Includes discussions on recent findings on the genetic and epigenetic regulation of polyunsaturated fatty acid metabolism

Book Description
Since the beginning of civilization, humans and animals have developed very strong associations to their mutual benefits. Livestock, particularly bovines, are important contributors to total food production in the world. The social expectations in Science and Technology are increasing because of rapid advances. Prevention and control of infectious diseases in bovines have been among the top-most public health objective in the last decade. In the present book, experts from different continents present important aspects of bovine science such as louse infestations of ruminants, cytogenetics of bovines, factors of competitiveness for bovines, feed manipulation, enhancement of conjugated linoleic acid and its bioavailability, emergence of antimicrobial resistance, and also meat quality. The aim of this book to provide an understanding of the present scenario, advances and challenges in bovine science.

Book Description
Interest in conjugated linoleic acid (CLA) has increased substantially in recent years. As one would expect with any evolving scientific area, research to date has provided more questions than answers. This book provides an up-to-date report of work that is still in progress. The editors document the state of knowledge about CLA as the twentieth century draws to a close.
