Example Embodiment
[0022] Example one:
[0023] 1. First determine the production formula for growing pigs
[0024] According to the nutritional standards for growing pigs formulated by the company, the digestive energy of pigs is not less than 13.65MJ / Kg, crude protein 18%~19.5%, lysine 1.05%~1.3%, lysine:methionine and cystine:threon The ratio of amino acid:tryptophan is 100:56:63:18, calcium is 0.7% to 0.8%, and phosphorus is 0.35% to 0.7%. The optimal formula composition (the best embodiment of the present invention) is calculated as:
[0025] Corn: 57.44%, imported fish meal: 1.5%, soybean meal: 22%, puffed soybean: 5%, sub-meal: 5%, rice hull: 3%, rice bran: 3%, soybean oil: 1.5%, sweetener: 0.03 %, composite enzyme preparation: 0.03%, 811 composite premix: 1.5%. 811 is a composite premix model, which can be purchased directly on the market. The fish meal is imported fish meal, which can guarantee the nutritional content.
[0026] 2. All the equipment used for preparation and use is purchased ...
Example Embodiment
[0037] Embodiment two:
[0038] The mass percentages of each component are: corn: 64.12%, fish meal: 0.2%, soybean meal: 20.3%, puffed soybean: 3%, sub-meal: 2%, rice hull: 2%, rice bran: 4.5%, soybean oil: 1.1% , Sweetener: 0.04%, compound enzyme preparation: 0.04%, compound premix: 1.9%. low cost.
Example Embodiment
[0039] Embodiment three:
[0040] The mass percentages of each component are: corn: 50.7%, fish meal: 1.5%, soybean meal: 24.7%, puffed soybean: 5%, sub-meal: 5%, rice hull: 5%, rice bran: 5%, soybean oil: 1% , Sweetener: 0.05%, compound enzyme preparation: 0.05%, compound premix: 1.5%. The nutrient level is high, and the growing pig grows fast.

Abstract
The invention discloses a formula feed of growing pigs and a preparation method thereof. The feed comprises the components with mass percents as follows: 50-65 corn, 0-2 fishmeal, 20-25 soya bean meal, 0-5 extruded soybean, 0-5 wheat middling, 0-5 rice pericarps, 0-5 rice bran, 1-2.5 bean oil, 0.03-0.05 sweetener, 0.03-0.05 compound enzyme preparation and 1.5-2 compound premix. The feed is prepared by the steps of removing impurities from raw materials, grinding raw materials, weighing raw materials, mixing raw materials, palletizing and packing finished products, etc. in sequence. The feed of the invention only selects the raw materials which are the favorite of the pigs and are easy to digest, such as the extruded soybean, by-products from rice processing, the sweetener and the like. The feed product has high digestible energy value and high nutrition level and is easy to satisfy the nutritional requirements in the growth stage, therefore, the growing pigs grow fast, the feed coefficient is low and the coefficient of the formula feed is 2.85-3.05.
Description
【Technical field】 [0001] The invention relates to the field of feed, in particular to a compound feed for growing pigs and a preparation method thereof. 【Background technique】 [0002] Worldwide, the breeding stages of meat pigs are generally divided into four stages: suckling pigs, small pigs, medium pigs, and large pigs. In actual production, small pigs are usually collectively referred to as growing pigs after their weight reaches 20kg. At present, the hog feed used by most breeding enterprises is generally divided into four types of feed according to the feeding stage, but in Jiaxing, Zhejiang, three types of hog feed have been formed, namely feed for suckling pigs, feed for piglets and feed for growing pigs. Among them, the growing pig feed is mainly used for feeding pigs over 20kg to slaughter, with a weight of over 90kg and a feed-to-weight ratio of no more than 3.1. [0003] The reports and researches on feed formula technology at this stage are mainly pig (universa...
