Cauliflower pens play a core role in large-scale cattle farms, providing isolation management, environmental control, and feeding support. For example, at a ranch in Ningxia, 3,000 calves are housed in individual "villa"-style calf pens forming modern "nursery units," with IoT technology monitoring temperature, humidity, and air quality 24/7.
In 2023, science and technology commissioners guided a livestock company in Handan, Hebei Province, in constructing "calf islands" as part of its infrastructure improvement efforts. In 2021, Mengniu Group's rescue efforts on collapsed calf islands following a severe snowstorm in Tongliao were selected as a sustainable development case study.
In daily care, the rice husks laid on the calf islands need to be kept to a depth of 25-30 cm. Milking temperatures should not exceed 38 degrees Celsius in summer and be maintained at 42 degrees Celsius in winter. Ranch technicians tailor scientific feeding programs to the individual growth differences of each calf.
