Common messenger molecules and cell types demonstrating neuroendocrine-immune interactions in the chicken
The aim of this study was to identify common messenger molecules used in both the immune and the neuroendocrine systems in birds, and to shed light on a cell type within the bursa of Fabricius that has historically been postulated as a potential neuroendocrine-immune link, the bursal secretory …

Tissue- and Development-specific Expression of Proton-mediated Peptide Transporters in the Developing Chicken
PepT1, PepT2 and PHT1 are all members of the proton-coupled oligopeptide transporter family, which are important in the transport of amino acids in peptide form. PepT1 acts as a low affinity/high capacity transporter and PepT2 as a high affinity/low capacity transporter for di- and tri-peptides. …

Effects of Yeast Product on Modulating the Adaptive Immune Function in Broilers
… was fed to broilers to investigate the effect of yeast products on the broiler immune function. The broilers were vaccinated for Newcastle Disease Virus on day 1 (B1 strain) and day 21 (LaSota strain) via eye drop. Body weights, feed consumption, feed conversion ratio, and mortality were …

Charakterisierung des Zytokins BAFF als wichtiger Regulator der B-Zellfunktion beim Haushuhn
This investigation is based on the identification of cDNA sequence information for a putative chicken homologue of the mammalian cytokine “B cell activating factor belonging to the TNF family” (BAFF) in a chicken EST-database. The cDNAs encoded for the complete open reading frame of chicken BAFF …

Evaluations of Techniques for Estimating Fall Age Ratios of Canada and Snow Geese
Validity of flock counts, average group-size counts, cannot-net catches, and hunter-bag checks for estimating productivity of lesser snow geese (Anser caerulescens caerulescens) and small Canada geese (Branta cnadensis hutchinsii-parvipes complex) was studied at Sand Lake and Tewaukon National …

Analysis of Bacterial-Host Interactions Between Campylobacter jejuni and the Avian Host During Commensalism
Campylobacter jejuni is a leading cause of bacterial enteritis in humans throughout the world. In contrast to the disease seen in humans upon infection, C. jejuni promotes an asymptomatic, intestinal colonization of many animals, especially avian species, to result in commensalism. The primary …

Effects of embryonic exposure to androgen-active endocrine disrupting chemicals in Japanese quail
… production, secretion, action, and elimination of endogenous hormones. EDCs have been shown to be responsible for disrupting development, reproduction, immune function, behavior, and all other life functions mediated by hormones. In the environment, organisms are exposed to many different types …

The application of Near Infrared Transmittance (NIT) individual kernel sorting technology to improve grain quality from spring and durum wheat infected with Fusarium and the effects on broiler chicken performance and immune response.
This project investigated the use of new near infrared transmittance (NIT) technology for individual kernel sorting to reduce Fusarium damaged kernels (FDK) and mycotoxins in grain. There were two objectives: 1) determine the efficiency of sorting; and 2) assess how highly contaminated sorted grain …

Skin breaking strength in broiler chickens
… to examine factors contributing to skin strength of meat-type chickens. Skin breaking strength was initially measured in lines of chickens divergently selected for high (H) and low (L) juvenile body weight, their reciprocal crosses (HL and LH), and an F₂ generation derived from HL and LH matings. …
