Primary breast cancer is breast cancer that has not spread beyond the breast or the lymph nodes (glands) under the arm. Breast cancer is not one single disease.There are several types of breast cancer, all of which can be found at different stages of development and grow at different rates.nvasive breast cancer. Invasive primary breast cancer is breast cancer that has the potential to spread from the breast to other parts of the body. The most common type of invasive breast cancer is invasive breast cancer of no special type (sometimes called invasive ductal cancer).
Ruminants are mammals that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again.s bacteria conduct fermentation in the rumen, they consume about 10% of the carbon, 60% of the phosphorus, and 80% of the nitrogen that the ruminant ingests. To reclaim these nutrients, the ruminant then digests the bacteria in the abomasum.
âThe first limiting nutrient is protein, simply because the ruminant needs protein to digest forage. If the cow doesnât have enough protein to create a proper environment for rumen microbes, she canât digest the fiber in low-quality forage to extract the energy value in it,â Olson says. He says the goal is to meet the requirements of the gut bugs, so they can digest the feed and meet the requirements of the cow. âWe feed the rumen bugs to grow more rumen bugs. After they digest the fiber and pass on into the small intestine, these microbes also become supplemental protein for the cow. Itâs a very efficient system,â Olson says.
