The use of whole concentrate to fatten the weaned lamb has the following advantages: First, the lamb grows fast in 3 months, and the early fattening can obtain a higher slaughter rate; second, the whole concentrate is fed with a small amount of labor, and the lamb is not easily digested. Disease can increase feed conversion rate and daily gain. The test proved that the lamb was weaned at 1.5 months of age and weighing 10 kilograms. After 50 days of fattening with whole concentrate, it can be marketed, with a body weight of 25-30 kg and an average daily gain of about 400 grams.
The specific fattening method is: the feeding of the lambs is carried out 15 days before the weaning of the lambs, and the lambs can be separated from the ewes in the morning and evening, the lambs are allowed to move in the special column, the trough and the sink are placed in the column, and the mother is placed at other times. Same place. At this time, the feed should be the same as the feed used for fattening after the weaning of the lamb. The feed formula is 83% whole corn, 15% soybean cake, 1.4% bone meal, 0.5% salt, and 0.1% vitamin and trace elements. During the fattening period, the tank can not be cut off and the clean drinking water is guaranteed. The corn kernels that are fed at the beginning can be slightly broken, and the lambs are used to feeding them. Keep the lamb active area dry, preferably with a little padding on the ground. Under normal circumstances, the lamb's feces are yellow-like, such as rainy weather, lambs can be treated with intestinal anti-inflammatory drugs when diarrhea occurs.
