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.
Research indicates that cattle readily drink water that is 40 - 90 F. Water intake will vary with environmental temperature and dryness of the feed. Cows eating lush grass on a cool spring day will drink much less water than cows grazing the same field in the middle of summer.Water requirements for cattle are given in Table 1. A good rule of thumb is cattle need 1.5 gallon for every 100 lbs of body weight.Table 1.esearch indicates that cattle readily drink water that is 40 - 90 F.
