Lambs are characterized by rapid weight gain, high feed remuneration, low product cost, short production cycle, and high economic benefits. Therefore, lamb fattening production has developed rapidly in recent years. Lamb fattening is a very technical job. In practice, strict implementation of various technical measures is required. Lambs have different fattening techniques due to their different body weights. The fattening techniques for different weaning lambs are as follows: (1) Lamb preparation before fattening is ideal for fattening and must be done before fattening Ready to work. The following aspects should be done before weaning lambs are fattened: (1) Doing a good job of lamb feeding and management.
