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.
Typically, a beef animal will consume three percent of its weight in dry matter. So for 1,000 pound beef cow that is 30 lbs. of dry matter a day. On average, dry hay is 88% dry matter, which means that the beef cow needs 34 lbs. of baled hay as fed per day to meet her intake. If we look at feeding our cow herd winter feed October through March, which would be about 180 days, each cow will consume about 3.06 tons of hay during that time period.
