  • South-central coastal Vietnamese farming systems are based on growing livestock, subsistence rice crops, and cash crops such as cassava, peanuts, and cashews. Increasing demand for beef in the major urban centres and consequent high beef prices provide opportunities for increased farmer income.
  • Cattle production is constrained by: limited resources, low fertility sandy soils, and harsh climatic conditions (high temperatures, long dry season, flooding in the wet season). Expanding cattle production is restricted by:the limited quantity and quality of feedspoor husbandry practices leading to long calving intervals, high calf mortality rates, low growth rates, and consequently low cattle productivity and efficiency.
  • Model output from baseline and various intervention strategies in Binh Dinh, run over a 10 year period. Final cash balance values do not take into account hired labour costs.
  • Some farmers are reporting labour savings of up to 2 hours/day
  • Explaining to extension workers his preference for various forages he has been testing.

    1. 1. Improving cattle profitability in mixed crop- livestock systems in south central coastal Vietnam using an integrated modelling approachParsons D, McDonald C, NX Ba, DT Tuan, Lisson S,Corfield J, LD Phung, NH Quan, NH Van, LD Ngoan, Lane P
    2. 2. Q. Can we use modelling tools to designimproved farming systems for smallholderbeef producers in Vietnam? TIAR – research • development • extension • education • training
    3. 3. “Better Integration of Beef Cattle Production with Crop Production Systems in South- Central Coastal Vietnam” •4-year ACIAR funded project •Commenced in 2009 UTAS/TIAR CSIRO Hue University Research and Development Centre for Animal HusbandryTIAR – research • development • extension • education • training

    7. 7. Defining the Farming System•Detailed household surveys (~60 households/commune)•On-farm biophysical monitoring (~10 households/commune) cattle were weighed regularly inventories of local feedstuffs Trialled potential suitable forage varieties•Workshops with farmers and other stakeholders (~20 people/commune)•Interviews with leaders, officials•Focus group discussions (~5 people/commune).

    9. 9. The Integrated Analysis Tool (IAT) •IAT was used to simulate crop, forages and livestock activities within local farming systems and assess their economic and social feasibility. •‘Best-bet’ options were chosen based on analysing the system and experience with application of practices that have been successful in other similar situations.

    16. 16. Implementing ‘Best-bet’ options•Using a farming systems approach we identified numerouspossible options to improve livestock production andhousehold welfare.•The simulation results suggest that the following managementpractices can greatly improve the profitability of a household: •improved forages •introduction of tree legumes •improved cattle management •herd size TIAR – research • development • extension • education • training
