Here is a general timeline for pig weight gain:
1. Weaning: Piglets are typically weaned from their mother around 4 to 8 weeks of age. At this stage, they usually weigh around 10 to 15 kg.
2. Nursery Stage: After weaning, piglets are moved to a nursery, where they receive a specialized diet and care to promote rapid growth. During this stage, they can gain anywhere from 0.5 to 1 kg per day.
3. Grower Stage: As the pigs grow older, they are moved to a grower barn. They continue to receive a high-quality diet and are monitored for proper weight gain and health. During this stage, they can gain approximately 0.7 to 1.2 kg per day.
4. Finishing Stage: In the finishing stage, the pigs are fed a diet specifically designed to increase their weight and improve their meat quality. During this stage, pigs typically gain around 1 to 1.5 kg per day.
So, based on this timeline, a pig can reach a weight of 70 kg in approximately 6 to 12 months. However, it is important to note that this timeline can be influenced by various factors, such as breed, genetics, feed efficiency, and overall pig management practices. Some breeds of pigs may grow faster or slower than others, and some farmers may use specific feeding strategies to accelerate weight gain.
