Cultivation of fattening lambs
The gestation period for ewes is generally a time of slower fetal development, so they don’t require high levels of nutrition during the early stages. In the grazing season, additional feeding is usually unnecessary. However, during the dry season, feeding them straw or hay can help maintain their energy levels. As the pregnancy progresses into the late stage, the fetus grows rapidly, and it becomes crucial to ensure a balanced diet. Along with regular grazing, providing 1–1.5 kg of hay, 1.5 kg of silage, and 0.45 kg of concentrate feed daily is recommended. The concentrate should include ingredients like cornmeal, soybean meal, bone meal, or shell powder, along with salt, vitamins, and minerals. It's also important to allow them regular exercise and access to sunlight, while ensuring clean, fresh water is always available. The sheep housing should remain clean, dry, well-ventilated, and comfortable—cool in winter and shaded in summer.
For nursing ewes, feeding requirements vary depending on whether they are raising one lamb or twins. Ewes with twin lambs need an extra 0.6 kg of concentrate per day between February and March postpartum, and 0.4 kg after April. Single-lamb ewes receive 0.5 kg of concentrate from February to March and 0.3 kg from April onward. Additionally, double-lamb ewes should be given 1 kg of high-quality hay, while single-lamb ewes get 1 kg of a mix of quality hay and wild grass. During late lactation, grazing remains the main source of nutrition, but small amounts of hay can be offered, and concentrate feed can be provided every few days as needed.
During the lambing period (from birth to 10 days old), the birthing area must be clean, dry, and well-ventilated, with temperatures above 8°C. Lambs should be encouraged to nurse colostrum within the first hour of life. Weak or multiple lambs may need assistance with bottle-feeding twice daily. From day 11 to 30, lambs should be introduced to forage early to stimulate rumen function and digestive development. Starting around day 10, a concentrate mix containing 20% soybean meal, 25% bran, 52% corn, 0.5% salt, and trace elements can be offered as boiled porridge, starting at 50–75 grams per day and gradually increasing. By day 20, small amounts of peanuts, eucalyptus leaves, and other roughage can be introduced.
From day 31 until weaning, lambs should graze with the flock to build their eating skills. To support rumen development, avoid overfeeding green feeds with high moisture content. This gradual approach ensures healthy growth and prepares the lambs for independent feeding.
