Concentrated feed for early stage of growing-finishing pigs

The invention relates to a concentrated feed for early stage of growing-finishing pigs. The concentrated feed is prepared from the following raw materials in parts by weight: 2-5 parts of S0512, 2-5 parts of alfalfa, 5-10 parts of calcium hydrophosphate, 5-8 parts of mountain meal, 3-5 parts of table salt, 2-5 parts of fish meal, 20-30 parts of soybean meal, 8-15 parts of cottonseed meal, 30-40 parts of wheat shorts, 2-5 parts of soybean oil, 2-5 parts of lysine, 0.3-0.6 part of threonine, 0.1-0.5 part of phytase, 0.1-0.3 part of a sweetening agent and 0.01-0.1 part of an antioxidant. The concentrated feed is applicable to the early stage of the growing-finishing pigs with the weights being 30kg-60kg. According to the feed, the cultivation cost problem can be solved (the cultivation cost is reduced by 13-20 yuan per pig); and the pigs can be adapted to the change of the feed and the nutritional requirements are met, and the time to market is shortened.
