Microgranular concentrated feed for growing-finishing pigs and preparation method thereof

Abstract

The invention discloses a microgranular concentrated feed for growing-finishing pigs. The parts by weight of the materials of the microgranular concentrated feed are as follows: 45.5 to 55.1 parts of non-genetically modified soybean meal, 8 to 15 parts of wheat, 1 to 2 parts of imported super steamed fish meal, 12 to 15 parts of cottonseed protein powder, 4 to 6 parts of calcium carbonate, 4 to 6 parts of rapeseed meal, 8 to 12 parts of extruded soybean, 1 to 2 parts of mineral premix, 0.2 to 0.3 parts of vitamin premix, 2.8 to 3.0 parts of calcium hydrophosphate, 5 to 7 parts of soybean oil, 1 to 2 parts of calcium propionate and 0.1 to 0.2 parts of feed-grade antioxidant. The materials of the formula are conditioned by a double-shaft differential conditioner, the conditioning steam pressure is 0.1Mpa to 0.2Mpa, the humidity is 15 to 19 percent, the temperature is 85 DEG C to 90 DEG C, the conditioning time is 20 to 30 seconds, and after curing, extrusion, granulation and cooling, granular concentrated feed is crushed into uniform microgranules. In the microgranular concentrated feed, crude protein is more than 30 percent, and fat is more than 7 percent; the microgranular concentrated feed is complete in nutrition, high in energy and low in protein, the feed utilization rate is high, and a growing-finishing pig can gain weight by more than 1000 grams per day.

Description

technical field [0001] The invention relates to the field of pig feed, in particular to a microparticle-type hard pellet feed for growing and finishing pigs and a preparation method thereof. The feed is specially used as a feed for growing and finishing pigs with a body weight of 50 kilograms-the period of slaughter. Background technique [0002] With the increasing shortage of feed protein resources, in order to reduce the waste of protein resources and maximize the growth potential of pigs, a high-energy microparticle-type concentrated feed has been specially developed, which reduces the use of protein raw materials and can achieve early consumption of feed for slaughter Less, low cost of breeding, and significant economic benefits for farmers. [0003] At present, the concentrated feed for growing and finishing pigs is generally powder or ordinary hard pellet feed. The powder has not been subjected to high-temperature modulation, and there is no sterilization process. Gen...

Problems solved by technology

At present, there is no suitable granular concentrated feed for growing and finishing pigs. This requires creative research and experiments on raw material components, the content of each raw material component, and suitable production processes, etc., to obtain food suitable for growing and finishing pigs, and Microparticle-type concentrated feed for growing and finishing pigs with reasonable nutrition, high digestibility and low feed coefficient
