Synthetic biology is the design and construction of biological devices and systems for useful purposes. It is an area of biological research and technology that combines biology and engineering, thus often overlapping with bioengineering and biomedical engineering.istinguished from older methods of transgenics by the use of either outright synthesised DNA or DNA which has been modified heavily to become more predictable and standardised. A heavy focus on modular design of genetic parts makes synthetic biology more of an engineering discipline than a form of pure science.
If the hay were 88% dry matter, on an as-fed basis, cows would eat about 32 (28 pounds/.88) pounds daily. If there were 200 head of cows in the herd, it would take about 3.2 ton of this hay per day [(200 head x 32 lb/hd/da)/2000lb] not accounting for any waste.
Cows eat grass, hay and other plant material that contain hard-to-digest cellulose. To cope with this they have a large stomach with four compartments, with the largest being the rumen. The rumen contains millions of tiny organisms that live and die inside the cow, and help to break down plant matter and release nutrients that the cow can digest.
