Two experiments were conducted to determine the concentration of DE and ME and the standardized ileal digestibility (SID) of AA in chicken meal, poultry byproduct meal, hydrolyzed porcine intestines, a spent hen–soybean meal (SBM) mixture, and conventional SBM fed to weanling pigs. In Exp. 1, 48 barrows (initial BW: 14.6 ± 2.2 kg) were placed in metabolism cages and allotted to 6 diets with 8 r...

In a recent account of methods of obtaining best-fit parameters of the parameters V and Km of the Michaelis-Menten equation, Tseng & Hsu (1990) appear to have misunderstood the method used by Lineweaver & Burk (1934), and to have overlooked much of the work done since 1934. The Michaelis-Menten equation represents the observed rate of v of an enzyme-catalysed reaction in terms of the two parame...

This study was to investigate the relationship between chick weight in growing period and laying performance of Korean native chicken (KNC) breeders. We measured body weights 1,384 KNC breeders at 1-140 days age two-week intervals. The first egg laying, hen-day hen-housed production, were investigated. Correlation coefficients production traits analyzed. results showed that correlation signific...

A study was conducted to evaluate the production and hatching performances of hilly chickens naked neck (NN) at areas Naikhongchari regional station research farm Bangladesh Livestock Research Institute (BLRI). The experimental were reared in an open-sided poultry house under intensive management system for a period 18 month. birds allowed take feed clean drinking water ad libitum. Data on prod...

The objective of this study was to compare the antimicrobial activity macrophages and serum in laying hen (MM, CC, CCc) broiler chicken lineages (TT LL). Macrophages were evaluated for phagocytic activity. Microbicidal by resistance test agar test. results showed that higher males MM strain, with 13% presenting phagocytosis, while other studied, even [...]

The purpose of our study was to examine the expression pattern of apoptosis-related genes in normal and cancerous ovaries of the hen. Localization of apoptosis-related gene mRNA was investigated in cancerous ovaries using in situ hybridization. The expression patterns of apoptosis-related genes were confirmed with RT-PCR in normal and cancerous ovaries. Differences of expression level between n...

The object of this investigation was to ascertain the sequelae of grafts of Rous chicken sarcoma placed subcutaneously in normal and resistant pure-bred barred Plymouth Rock chickens. Eous and Murphy placed small pieces of Rous sarcoma suboutaneoasly in normal barred Plymouth Rock chkkens, and removed them at intervals along with the surrounding tissue. From microscopic study they found that th...

Tumor necrosis factor (TNF) family ligands bind to death domain-containing TNF receptors (death receptors), which can subsequently activate intracellular signaling pathways to initiate caspase activity and apoptotic cell death. Decoy receptors, without intracellular death domains, have been reported to prevent cytotoxic effects by binding to and sequestering such ligands, or by interfering with...
