There are two major advantages to weaning lambs with full concentrates:
First, lambs grow fast within 3 months of age. Early slaughter can get a higher slaughter rate; second, use full concentrates to feed a small amount of labor, and lambs are not prone to digestive diseases, which can increase feed conversion rate and daily gain. . Tests have shown that lambs are weaned at 1.5 months of age and weighing up to 10 kilograms. They can be marketed after 50 days of all-fermented fattening, weighing 25 to 30 kilograms, with an average daily gain of about 400 grams.
Specific fattening methods are as follows: After the lambs are fed for 15 days before weaning, the lambs can be separated from the ewes in the morning and at night. The lambs are allowed to move in special columns, and the troughs and sinks are placed in the columns. Same place. The supplementary feed should be the same as the feed used for fattening after weaning. The feed formula is 83% corn, 15% soybean cake, 1.4% bone meal, 0.5% salt, and 0.1% vitamins and trace elements. During the fattening period, no material can be cut in the tank, and clean drinking water is guaranteed. The corn grains that are supplemented at the beginning can be broken slightly, and the whole lamb can be fed after the lamb is used.
