Plant Breeding and Biotechnology

19.0K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Key Elements for Plant Nutrition

18.8K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Area of Science:

  • Agricultural Science
  • Animal Science
  • Precision Agriculture

Background:

  • Growing global demand for sustainable farming drives pasture-based dairy herd expansion.
  • Precision dairy technologies offer potential benefits for animal welfare, farm efficiency, and cost reduction in grazing systems.
  • Wearable technologies provide data on dairy cow activity, rumination, and grazing behavior.

Purpose of the Study:

  • To explore the application and benefits of precision dairy technologies in pasture-based dairy farming.
  • To assess the accuracy of wearable technologies in monitoring grazing behavior and pasture intake.
  • To investigate the potential of emerging technologies for monitoring forage availability and optimizing grazing management.

Main Methods:

  • Utilizing wearable technologies to record activity, rumination, and grazing behavior in dairy cows.
  • Comparing data from wearable technologies with visual observations to determine accuracy.
  • Exploring the use of satellite technology (Normalized Difference Vegetation Index) and rising plate meters for forage biomass assessment.

Main Results:

  • Wearable technologies show moderate to high correlations (r = 0.65–0.88) with visual observations for rumination, eating, and inactivity.
  • Grazing behavior data collected with wearable technologies demonstrated high correlation (r = 0.92–0.95) with visual observations.
  • Current technologies like satellite imagery and rising plate meters show promise for monitoring forage biomass.

Conclusions:

  • Precision dairy technologies, particularly wearable sensors, can accurately monitor grazing behavior in pasture-based systems.
  • Accurate monitoring of forage availability using technologies like satellite imagery and rising plate meters can enhance dairy farm efficiency and production.
  • Future advancements in virtual fencing, drones, and autonomous vehicles will further support pasture-based dairy farming.
