Miniature Jersey
Overview
Miniature Jersey cattle are compact dairy cattle standing 36-42 inches at the shoulder, developed through selective breeding of the smallest standard Jersey cattle. These diminutive cows retain all the exceptional milk quality that made Jersey cattle famous - rich, creamy milk with the highest butterfat and protein content of major dairy breeds - while requiring only a fraction of the land and feed. Miniature Jerseys are true purebred Jerseys, not crossbreds or dwarf cattle, but rather carefully selected lines bred for reduced size over multiple generations. Their small stature, gentle disposition, manageable milk production for family use, and efficiency make them the ideal family milk cow and increasingly popular for small homesteads, hobby farms, and anyone wanting fresh dairy products without the commitment of full-size cattle. Note: If you have more pasture available and are looking for higher daily milk volume, compare these traits with the Standard Jersey Cow.

Temperament
Miniature Jersey cattle inherit the gentle, intelligent temperament that makes standard Jerseys beloved family cows. They are exceptionally docile, friendly, and affectionate, often seeking human interaction and attention. Their calm, patient nature combined with their small size makes them ideal for families, children, and first-time dairy cattle owners.
Miniature Jersey cows are cooperative during milking and handling, making them perfect for hand milking operations. They bond closely with their caretakers and respond well to consistent, gentle handling. Bulls are notably calm and manageable compared to larger dairy breed bulls, though all bulls require proper respect. The breed's sweet disposition, combined with their beautiful appearance and manageable size, makes them truly enjoyable animals to work with on small farms and homesteads.
