There are many advantages for lambs to adopt early weaning and full-fat fattening techniques. First, lambs grow fastest within 3 months of birth. After that, the growth rate slows down. Early slaughtering has a higher slaughter rate. Second, the technology feeds only concentrates. No roughage is fed, so management is simple and no gastrointestinal disease occurs, thus increasing the feed conversion rate and daily gain. According to tests, lambs were weaned at 1.5 months of age and weighing 10 kilograms, fattened for 50 days, and slaughtered at the age of 3 months. The fattening sheep weighed 25-30 kilograms, and the average daily gain was about 400 grams. The economic benefits were significant. (1) Pre-fat preparation Lambs are weaned at 1.5 months of age, supplemented by fences for the first 15 days, or separated from the ewes in the morning and at night. The lambs are allowed to move in the special column, and the concentrate is placed in the activity column. Grooves and drinking troughs should be kept at the same time at other times. Supplemented feeds should be the same as feeds that are fattened after weaning. The supplemented corn kernels can be slightly broken at the beginning, and then used to feed whole grains afterwards. The lambs should be kept dry in the activity area and covered with a few beddings on the ground. (b) The main points of whole fattening and finishing (1) Selection of fattening feed. Generally, the fattening effect of corn is better, and the ratio of feed is: 83% of whole corn, 15% of bean cake, 1.4% of bone meal, 0.5% of salt, and 0.1% of vitamins and trace elements. (2) Don't change the feed formula during the fattening period. (3) During the fattening period, the tank is continuously fed to ensure clean drinking water. (4) Check the feces regularly. In general, the feces are yellow lumps. In case of rainy days, diarrhea may occur. If necessary, anti-inflammatories can be used for treatment.
