The main nutritional feature of soybean meal is that there are more rumen-degraded proteins, which can provide more nitrogen sources for rumen microorganisms. As a high-energy protein raw material, expanded soybeans can provide rumen-passed protein and fat for dairy cows. The content of saturated fatty acid is high, which usually limits the dosage of its formula, and the daily feed intake of each cow is generally controlled at about 0.5-1kg
[0003] In addition, directly increasing the amount of soybean meal in ruminant diets due to rumen action is extremely inefficient and very costly

Embodiment 1
[0034] (1) 925kg soybean meal is crushed and sieved through a 3mm sieve;
[0035] (2) Mix the sieved soybean meal with 50L 15% xylose aqueous solution evenly, and prepare it at 90°C for 35 minutes;
[0036] (3) Extruding the soybean meal prepared in step (2) at 130°C;
[0037] (4) Heat 25L soybean lecithin oil to 40°C, and evenly spray it on the surface of the expanded soybean meal;
[0038] (5) Rapid cooling at 15°C, until the temperature of the soybean meal drops to 40°C to obtain the rumen-passed soybean meal.
Embodiment 2
[0040] (1) 915kg soybean meal is crushed and sieved through a 3mm sieve;
[0041] (2) Mix the sieved soybean meal with 60L 13% glucose aqueous solution; prepare at 90°C for 35 minutes;
[0042] (3) Puffing the soybean meal prepared in step (2) at 135°C;
[0043] (4) Heat 25L soybean lecithin oil to 45°C, and spray evenly on the surface of the expanded soybean meal;
[0044] (5) Rapid cooling at 15°C, and the rumen-passed soybean meal is obtained when the temperature of the soybean meal drops to 45°C.
Embodiment 3
[0046] (1) 915kg soybean meal is crushed and sieved through a 3mm sieve;
[0047] (2) Mix the sieved soybean meal with 60L 13% xylose aqueous solution evenly, and prepare it at 100°C for 20 minutes;
[0048] (3) Puffing the soybean meal prepared in step (2) at 130°C;
[0049] (4) Heat 25L soybean lecithin oil to 50°C, and evenly spray it on the surface of the expanded soybean meal;
[0050] (5) Rapid cooling at 15°C, until the temperature of the soybean meal drops to 40°C to obtain the rumen-passed soybean meal.

Abstract
The invention discloses rumen bypass soybean meal and a preparation method thereof. The rumen bypass soybean meal comprises the following raw materials in parts by weight: 870-935 parts of soybean meal, 45-80 parts of a soluble sugar aqueous solution with the mass concentration of 5-20% and 20-50 parts of grease. The invention also discloses a preparation method of the rumen bypass soybean meal. Through dual protection of a puffing process and grease spraying, degradation of the soybean meal in rumen is reduced, the rumen bypass rate of the soybean meal and the absorption rate of the soybean meal in small intestines are remarkably improved, meanwhile, milk is increased, protein is extracted, and heat stress of animal bodies in summer can be relieved.
Description
technical field [0001] The invention relates to the field of animal feed. More specifically, it relates to a rumen-passed soybean meal and a preparation method thereof. Background technique [0002] In the process of raising dairy cows, soybean products are the main source of high-quality protein and amino acid nutrients, which not only provide nitrogen sources for the growth of rumen microorganisms, but also provide nutrients for the metabolism of dairy cows. At present, soybean products used in China are mainly soybean meal and expanded soybeans. The annual consumption of soybean meal per cow is 600-800kg, and the consumption of expanded soybean per cow is 150-200kg. The main nutritional feature of soybean meal is that there are more rumen-degraded proteins, which can provide more nitrogen sources for rumen microorganisms. As a high-energy protein raw material, expanded soybeans can provide rumen-passed protein and fat for dairy cows. The content of saturated fatty acid...
