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.
All cattle will eat primarily between 1.6% to 3.0% of their body weight per day (on a Dry-Matter [DM] basis), depending on the quality of the forage they are consuming.Dry cows, heifers, steers and bulls tend to eat around 2.0% of their body weight per day, on average.ig cows eat more than small cows, and thin cows will eat more than fat cows. Also, as you will notice in the related question posted below, moisture content in the feed and the quality of the feed will affect how much an animal will eat per day. Usually, the higher the moisture content, the more a bovine will eat.
