  • Biotechnology
    The application of biology to create fresh products, processes, and creatures that aim to benefit human health and society
  • Biotechnology has been around since the beginning of civilization, with the domestication of plants and animals and the discovery of fermentation
  • Biotechnology is interconnected with several branches of Science, each with a purpose for contributing to the lives of people within our society, including the branch of Agriculture
  • Agriculture
    Humans are environmental engineers who disrupt the livings' habitats in particular ways
  • Biotechnology
    • Provides tools for the farmers to make a much cheaper and manageable production
    • One example is the engineered crops that were made through biotechnology, which tolerates herbicides making the weed control more simple and efficient
  • Use of artificial insemination (AI) in dairy farming
    1. Importing high milk-yielding breeds like Holstein/Friesians
    2. Establishing the National AI Center (NAIC) to locally produce and distribute semen
    3. Crossbreeding the Malawi Zebu with superior dairy genetics through the use of imported semen
  • Adoption of AI
    Significant increases in average milk yields, from 2-3 liters per day for Zebu cows to 8-15 liters per day for the crossbred animals
  • Milk marketing is organized through milk bulking groups (MBGs) that bulk milk and sell to processors
  • A typical farmer can earn net profits of around $6,240 annually from milk sales with a herd of 10 crossbred cows
  • Challenges remaining
    • Limited availability of high-yielding breeding stock within the country
    • Irregular supply of semen and liquid nitrogen for AI
    • Low-input feeding systems limiting productivity
    • Low AI adoption rates with only 10% of the national herd bred through AI due to service delivery constraints
  • Lessons learned highlight the need to improve domestic breeding populations and AI service delivery to reduce dependence on genetics imports for sustainable dairy development
