    • 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
