Embodiment 1

[0017] Embodiment 1 The preparation of fiber-derived composite additive for pigs

[0018] 1. Preparation of Microencapsulated Coated Fatty Acid Particles

[0019] The following are calculated by weight of the substance.

[0020] Stir 48% tributyrin, 11.8% rice husk powder, and 7% corncob at a speed of 30-90rpm for 20 minutes, mix well, then add 0.5% calcium acetate and 6% sodium propionate and continue stirring for 15 minutes to mix well. Swing granulation, pull air drying, the air inlet temperature is 40-80 °C, and the air outlet temperature is normal temperature; weigh 6% stearic acid and 20% glyceride, add 0.5% absolute ethanol and 0.2% acetone to fully dissolve, as a package Coating liquid: In the coating equipment, the flow rate is 1-2L / min, the inlet air temperature is 50-60°C, and the outlet air temperature is normal temperature (not exceeding 40°C), and the time is 4 hours, and the microencapsulation is obtained Coated with fatty acid granules, more than 80% of the p...

Embodiment 2

[0024] In order to verify the application effect of the fiber-derived composite additive for pigs of the present invention, preliminary applications have been made in some pig farms such as Sichuan, Guangxi, and Guangdong.

[0025] In three pig farms, 390 DLY weaned piglets were added the fiber-derived composite additive for pigs prepared in Example 1, and the dietary formula was prepared with reference to NRC (58.41% corn, 15.5% soybean meal, 12% extruded soybean, 5% fish meal , whey powder 5%, sucrose 2%, compound multidimensional 0.04%, compound amino acid 0.1%, ore additive 0.5%, calcium hydrogen phosphate 0.5%, stone powder 0.65%, salt 0.3%, weight percentage), test group 3% (weight percentage) Percentage) The pigs prepared in Example 1 replaced 3% corn of the control group with fiber-derived compound additives, and the remaining feed materials were used in the same amount; the control group and the test group were all fed ad libitum, and fed for 21 days. The same procedu...

Embodiment 3

[0036] Through the 0-95 days of gestation rations for primiparous Landrace×Large White sows (the diet formula of the control group, calculated by weight percentage: corn 78.45%, soybean meal 16.9%, amino acid compound additive 0.25%, multidimensional and mineral mixed pre Mixture 0.95%, sodium bicarbonate 0.2%, calcium hydrogen phosphate 1.5%, stone powder 1.35%, salt 0.4%; The formula of test group adds 8% fiber-derived composite additives for pigs prepared in Example 1 on the basis of control group to replace 8% (by weight) of the fiber-derived composite additive for pigs prepared in Example 1 was added to the control group (8% corn). Feed the same diet from 95 days of gestation to delivery and lactation. At 08:00 and 16:30 every day, feed according to the daily prescribed feed intake, feed 2kg for 0-30 days, and feed 2.6kg for 30-95 days, check the amount of remaining material every week, and record in detail the amount of feed intake, remaining material and contaminated f...

Abstract

The invention discloses a fiber-derived compound additive for pigs and a preparation method of the additive, and relates to the field of animal feed. The method takes tributyrin, rice hull powder, corncob, calcium acetate, sodium propionate, stearic acid and glyceride as raw materials, and comprises the steps of firstly preparing fatty acid particles coated by microencapsulations; after that, evenly mixing betaine, wheat bran, oat bran, psyllium, inulin, pectin, guar gum, sodium alginate and Arabic gum step by step, and adding the fatty acid particles coated by microencapsulations into the mixture; finally, adding corn starch, and evenly mixing to obtain the fiber-derived compound additive for the pigs. After the fiber-derived compound additive for the pigs is adopted, the development and health of intestinal tracts of piglets are effectively promoted, the reproductive performance of the pigs is improved, the health condition of the animal organism is improved, and the incidence rate of diseases can be reduced.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a fiber-derived composite additive for pigs and a preparation method thereof. Background technique [0002] As we all know, the health status of pigs in a pig farm is the key to its ultimate benefit. Having a high-yield and healthy pig herd can increase the annual slaughter volume of the pig farm, effectively reduce the production cost of pigs, and thus increase profitability. How to improve the health status of pig herds and reduce feeding costs has become the key to making pigs profitable. As an important organ for digestion and absorption of various nutrients in the body, the intestine is an important organ for animals to obtain material basis for production and reproduction; at the same time, as the largest immune organ of the body, it is also the front line and one of the main battlefields for resisting external pathogenic infections. It can be seen that the health and normal fu...
