Newborn calves have undeveloped rumens, and their digestive systems function similarly to those of humans. At this stage, only highly digestible, high-quality, and palatable ingredients should be used in calf feeding. The goal in calf nutrition is to increase live weight and feed intake and achieve weaning within 6–8 weeks at most. Calves must be given 2–3 liters of colostrum within the first 30 minutes after birth, followed by 1–2 liters within the next 4–6 hours. During the first 24 hours, calves should consume 5–6 liters of colostrum. On the second and third days, calves should be fed a total of 4–4.5 liters of colostrum in 3 equal meals per day. The recommended milk feeding temperature is 38.5–39 °C. Daily intake of Filiz Calf Starter Feed should be monitored, and by 5 weeks of age, high-quality dry forage such as alfalfa hay should be introduced. Forages such as straw or corn silage should not be given until calves are over 4 months old. Calves must always have access to clean, lukewarm water. Water is crucial to stimulate feed intake and promote rumen development.
