Breeding sheep management technology
Breeding sheep refers to young sheep that are between the time of weaning and their first breeding. After being weaned, which typically occurs at 3-4 months of age, these lambs grow rapidly, with significant weight gain and high nutritional demands. As they reach 8 months of age, their growth rate begins to slow down, and their feeding needs shift.
During the early breeding phase, especially for newly weaned lambs, their rumen is still developing and not fully functional, which limits their ability to digest roughage effectively. Therefore, their diet should primarily consist of concentrates, supplemented with high-quality hay and fresh green feeds. The crude fiber content in their feed should be kept below 15%-20% to support efficient digestion and growth.
As the lambs enter the rearing period, their rumen function becomes more mature, allowing them to better utilize forages such as pasture, silage, and stored straw. At this stage, the proportion of roughage in the diet can be increased to 25%-30%. However, it's still important to provide a balance by including concentrate feeds or high-quality silage and hay to ensure proper nutrition and development.
Proper management during the breeding period is crucial, as it directly impacts the reproductive performance of the sheep. Female lambs can reach a weight of around 40 kg by 6 months of age and are typically ready for breeding by 8 months. In many cases, over 80% of the female lambs born in a given year are bred within the same year. This makes the care and feeding during the breeding period extremely important for long-term productivity and flock health. Ensuring adequate nutrition, monitoring health, and maintaining a stress-free environment are all key factors in successfully raising breeding sheep.
