چکیده
Nutritional advances as discussed in these proceedings embrace historical perspective as well as futuristic perspectives. Indeed, we must have a clear understanding of the past to identify key “advances” that will mold the future of poultry nutrition. Early nutrition research is discussed with reference to in ovo nutrition and nutritional needs up to day seven post-hatch. In addition, the nutrition of the hen is key in early nutrition of chicks. Key advances that have impacted diet formulation are energy and nutrient liberating enzymes, and the use of L-threonine. Key nutritional mechanisms that have been elucidated the past two decades include nutrition in immunity and gut health. Advances in nutritional specifications for specific genetic strains of broilers and the use of models to tie nutrition into production objectives are clear advances that will only flourish in the future.

During the past two decades, techniques for the non-invasive analysis of fecal steroid metabolites (estrogen, androgen, progestagen and glucocorticoid metabolites) have been developed. These techniques have been used for research with mammals, birds, reptiles, and to a lesser extent in fish; species studied included domestic and laboratory animals, as well as captive and free-ranging wildlife. ...
متن کاملSituations Leading to Oxidative Stress in Dairy Cattle
Free radicals are normally produced by living organism, at controlled production rate they perform physiological functions as signal transduction molecules. However, situations leading to an overproduction that surpasses antioxidant capacity creates oxidative stress. Consequently, damage to the cell membrane, protein, DNA and cell death are observed. Dairy cattle are susceptible to oxidative st...
