The ewe is the foundation of flock breeding: understanding its characteristics and breeding value

The ewe is the female individual in a sheep flock, responsible for reproducing offspring within the flock. Compared with the ram, it is usually smaller in size and of a more docile temperament, and it is the first thing farmers consider when building a foundation flock.

Many people wonder whether ewes have horns. In fact, whether horns are present mainly depends on breed and genetics, and not all ewes grow horns. In some breeds, the ewes have smooth, hornless heads, while in others they have only inconspicuous horn bases; in a few breeds, ewes can even grow large spiral horns, and all of these are normal occurrences.

The breeding value of ewes is mainly reflected in reproduction. Once sexually mature, a ewe comes into estrus cyclically, and the gestation period is about five months; after lambing, she nurses the lambs with her milk. A ewe's lambing performance and the quality of her milk are closely related to breed, nutritional level and day-to-day management.

Among common sheep breeds, ewes have different strengths. The Small-tailed Han sheep is known for its strong reproductive capacity and is suited to a production direction focused on lambing; in fine-wool breeds kept mainly for wool, the wool quality of the ewes receives more attention. In recent years, research institutions have also bred sheep of different coat colours through genetic modification technology, adding ornamental and research value to flocks.

Raising ewes requires care by stage. During the non-pregnant period, the focus is on restoring body condition, while in late pregnancy and during lactation the nutritional requirements are higher, making a combination of green and coarse fodder with an appropriate amount of concentrate suitable. At the same time, keep the pen dry and well ventilated, and carry out vaccination and deworming on schedule; when the ewes are in good condition, the survival rate of the lambs will naturally improve as well.
