Glutamine is also a precursor for the synthesis of nucleotides purine and pyrimidine that are essential for the proliferation of lymphocytes, and mucosal cells Wu, 1998. But they are less amenable to reliable testing and explication. Other promising immunostimulants include astragalus, garlic, ginseng, green tea, Guduchi Tinospora cordifolia , maca, and Reishi mushrooms Ganoderma lucidum , or extracts from them. A hi-tech intravenous approach scores much lower than simple nutritional supplements in these regards, but it might prove somewhat more effective. Still, in a future version, it might make sense to include them. American Journal of Physiology 273: E408-E415.

Arginine metabolism: nitric oxide and beyond. Chemistry and neurochemistry of the kynurenine pathway of tryptophan metabolism. Can J Anim Sci 83 3 : 365-373.
How can we compare apples and oranges? Functional amino acids and fatty acids for enhancing production performance of sows and piglets. Amino acid requirements in inflammatory states. A stable intestinal microflora is typically attained post-weaning and during early childhood, and forms an essential component of the functioning human body. A deficiency or excess of dietary threonine reduces protein synthesis in jejunum and skeletal muscle of young pigs. Dietary tryptophan helps preserve tryptophan homeostasis in pigs suffering from lung inflammation. Effects of graded levels of true ileal digestible threonine on performance, serum parameters and immune function of 10-25 kg pigs. Effects of the immune system on metabolism: implications for production and disease resistance in livestock.
Can J Vet Res 67:283-290. Chapter: 14 Page no: 273 Author s : Brandtzaeg, P. Although reduced intake appears to be the prime driver for weight loss in infective states, infection may reduce the ability of the body to utilize nutrients. Br J Nutr 111, 101-110. In addition to digestion, absorption and metabolism of nutrients, the intestinal epithelial cells i.
Feeding wheat bran and barley based diets which are high in fiber hemicellulose increase endogenous losses of Thr in growing pigs compared with those fed a casein based diet Myrie et al. Mucosal immunity and gastrointestinal antigen processing. Immunity system in pigs The immune system is an adaptive defense system to protect the host from invading pathogenic microorganisms, i. Under normal circumstances, these resident gut bacteria cause neither pathogenesis nor inflammation in the host, but instead contribute to health maintenance, by forming a barrier layer against colonization by pathogens and by aiding in nutrient digestion and assimilation Salminen et al. Table 3: Effect of dietary glutamine on the performance of weaned pigs Zou et al.
There are two components of immune system: innate nonspecific and acquired specific immunity. Good nutrition works against bacteria growing in the digestive tract in the case of diets that are too highly fermentable. Probiotic Supplementation of the Intestinal Microflora Among the most predominant microbes in the human intestinal tract are the Gram-positive lactic acid-producing genera Lactobacillusand Bifidobacterium. Among the many purported physiological influences of probiotic microorganisms, a large proportion of research attention over the last decade has focused on the interaction of probiotics with the immune system Salminen et al. Critical review in Biochemistry and Biology 27: 57-92.
Minerals: Zinc has proven immunostimulative effects Prasad, 2002. Bookseller: , Essex, United Kingdom. An overview of the immune system. For-profit corporations will not fund clinical testing of low-cost interventions like homeopathy, while billions of dollars have been poured into research on cytokines and other immune system molecules by corporations seeking profits and government scientists interested in hi-tech research. This book provides a review of the roles of specific nutrients in maintaining the immune response and host protection against infection. Impact of immune system stimulation on ileal nutrient digestibility and utilization of methionine plus cysteine intake for whole body protein deposition in growing pigs.
Met + Cys, Trp, Thr, Gln, Arg and Gly in pigs are described. The persuasive clinical data regarding the effectiveness of Biophotonic Therapy, for instance, must oblige serious scientists to delve deeper. In this context, contact between gut-dwelling bacteria and intestinal cells may be considered part of the routine microbial signalling processes of a healthy gut microflora, forming a homoeostatic mechanism for the regulation of intestinal inflammation. Journal of Animal Science 86: 609-619. Animal Feed Science and Technology 78: 179-188. It also considers the influence of various factors, such as exercise and ageing, on the interaction between nutrition and immune function. Nutrition and Immunity through the Life Cycle.
