Newly hatched chicks lack immunological maturity, which could compromise their ability to respond to infection by pathogens such as Salmonella enterica serovar enteritidis (S. enteritidis; SE). A study was conducted in which chicks were infected with a sublethal dose of SE at 1 d posthatch, and the systemic and intestinal immune responses to the challenge were followed over time. Birds infected...

The objective of this study was to determine the concentration of total selenium (Se) and the proportions of total Se comprised as selenomethionine (SeMet) and selenocysteine (SeCys) in the postmortem tissues of female pheasants (Phasianus Colchicus Torquator) offered diets that contained graded additions of selenised-enriched yeast (SY) or a single comparative dose of sodium selenite (SS). Thi...

the effects of various methods of probiotic administration in hatchery and on prevention of salmonella enteritidis (se) in broiler chicks was investigated. a total of 150 salmonella free day old chicks (ross 308) were assigned to five experimental groups including control and four in-hatchery probiotic administration method groups comprised of: in ovo injection, oral gavage, spray and vent lip ...

The Tsunami in 2004 devastated Sri Lanka. In its aftermath, followed aid and support from multiple sources. As countries in South Asia ready themselves for climate change and the possibility of increased frequency in natural disasters, it is useful to understand how well post disaster operations work to help victims. It is vital that a country’s post-disaster development aid is well targeted an...

This study was envisaged to comprehensively profile genes in selected tissues along with a few biochemical indicators and integrate resulting information with dietary selenium (Se) deficiency symptoms in broilers. A total of 120 one-day-old Cobb male broilers were equally divided into two groups and fed a Se deficient corn-soybean-based basal diet supplemented with 0.3 mg/kg sodium selenite (Co...

The synthesis of D- and L-selenomethionine labeled with ⁸²Se and three deuteriums at Se-methyl group (D- and L-[²H₃, ⁸²Se]selenomethionine) was described. D- And L-[²H₃, ⁸²Se]selenomethionine were prepared by condensation of (R)- and (S)-2-amino-4-bromobutylic acid with lithium [²H₃, ⁸²Se]methaneselenolate, which was prepared from metal (82)Se and [²H₃]methyl iodide. The optical purities of D- ...
