Recombinant outer membrane protein H (rOmpH) of Pasteurella multocida strain X-73 can be purified using affinity chromatography but this adversely affects its immunogenicity. The current study presents the results from an intervention study comparing the immunogenicity of rOmpH purified using electroelution with rOmpH purified using affinity chromatography and native OmpH purified using electro...

The objective of this investigation was to study the histological and histochemical structure of the Harderian gland in native chickens. Samples were obtained from 10 male and 10 female adult healthy native chickens. Tissue sections were stained with haematoxylin eosin, Verhoeff ’s, Masson’s trichrome, alcian blue (pH 2.5), periodic acid-Schiff and Gomori’s method for reticulum. The multilobula...

The Effect of Lactobacillus Reuteri Isolated from Gastrointestinal Tract Iranian Native Poultry on Growth Performance, Carcass Characteristics, Blood Parameters and Immune Response Broiler Chickens

Received: Revised: Accepted: Published online: December 28, 2014 July 11, 2015 October 05, 2015 January 01, 2016 Endogenous viral loci, designated as avian leukosis virus subgroup E (ALVE), have been found in the genome of commercial chickens. They sometimes modulate the host physiologic processes by changing the expression level of host promoters near an integration site. Therefore, the identi...

We evaluated the immunomodulatory effects of a proanthocyanidin-rich extract (PAE) from Pinus radiata bark in Korean native chickens. In experiment 1, proliferation of peripheral blood mononuclear cells was significantly enhanced in chickens administered 1.25, 2.5, 5, and 10 mg/kg of PAE for 2 wk once daily by oral gavage compared with no administration of PAE in vitro. Proliferation of splenoc...

Partitioning of ecological niche is expected in lekking species that show marked sexual size dimorphism as a consequence of sex-specific ecological constraints. However, niche partitioning is uncertain in species with moderate sexual dimorphism. In addition, the ecological niche of a species may also be affected by landscape composition; particularly, agricultural fragmentation may greatly infl...

Sentul chicken is one of Indonesia’s native chickens that has high potential for meat and egg production performance. The breeds with body resistance the solutions to fulfill this potential. This research aimed ascertain impact various IgY concentrations (high, medium, low) on 90 Debu Kelabu chickens. Parameters observed included pre-laying laying Six replications a completely randomized design...
