an experiment was conducted to investigate the effects of using different levels of red pepper powder (rp) and marigold flower powder (mf) on egg production, egg yolk color andsome blood metabolites in laying hens. ninety, 103-weeks old laying hens were divided into 5 treatments groups of 6 birds in each cage with 3 replicates in a completely randomized design. the birds were fed a corn-soybean...

Data of four layers flocks (#31-34) from North Carolina Layer Performance and Management Test of the Department of Agriculture and Consumer Services were used in the meta-analysis to find if an increase in space allowance can affect egg production traits in white and brown layers. Effects of space allowance of 310 and 413 cm2/bird on layers performance were compared in this study. The increase ...

The smooth muscle cell (SMC) cultures were prepared from the aorta of male and female 8-week-old rats and used at passage 5-7 or 40-45. On day 1, low-passaged cells of both sex groups adhered to growth supports at similar numbers while after repeated passaging the adherence of female-derived cells was higher. These cells had also higher total protein content and contained more of the SMC specif...

The myeloid lineage to which HL-60 promyelocytic leukemia cells will differentiate in response to a chemical differentiation inducer can be switched by altering the pH of the growth medium. Cells passaged previously at pH 7.2 become neutrophiles, and those passaged previously at pH 7.6 become eosinophiles after 5 to 7 days of culture in the presence of 0.5 mM butyric acid. Butyric acid and its ...

Cryptosporidium parvum TU502, a genotype 1 isolate of human origin, was passaged through three different mammalian hosts, including humans, pigs, and calves. It was confirmed to be genotype 1 by PCR-restriction fragment length polymorphism analysis of the Cryptosporidium oocyst wall protein gene, direct sequencing of PCR fragments of the small subunit rRNA and beta-tubulin genes, and microsatel...

RF mice with primary and passaged radiation-induced myeloid leukemia were ex amined with the electron microscope for the presence of virus particles. The spleen, liver, and bone marrow of nearly all such mice examined contained small numbers of these particles. In one of two animals in which other tissues (thymus, pancreas, salivary glands, lymph nodes, omentum, lung, and brain) were examined, ...
