F. E. Integrated Crop/Livestock/Fish  Farm. A demand-driven bio-economic simulation model of a one-cow  herd has been developed to compare three animal types, native  swamp buffalo, dual purpose river buffalo and cross- bred dairy  cow.  The herd structure was generated for ten years with some  stochastic biological events, and the dry matter, metabolisable  energy and digestible nitrogen inputs from pasture and rice straw  has been input, to determine the needs of concentrate feed to  achieve the biological potential of the herd. Considering the  outputs of milk, meat and calves, a partial budgeting was done  to compare the economics of the three animal types, replicating  the experiment ten times.  A complete economic analysis was also performed to see the  economic feasibility of the three animal types reared for milk.  The model has been validated, and the sensitivity for milk price  and combination of milk price and concentrate cost, analysed.  Dairy cow was the best, while milk production from the  native buffalo was not at all profitable. 0aLivestock 0aAgricultural systems1 aPeacock, Christabel P., eChairpeson1 aGartner, Joseph A., eExamination Committee1 aWaibel, Hermann, eExamination Committee2 aDAAD (German Government)., eScholarship Donor2 aAsian Institute of Technology.tthesis ;vno.
