Problems solved by technology

However, the literature on the effect of folic acid on the production performance and body metabolism of dairy cows is very limited, especially the application of rumen-passed folic acid and the combined use of rumen-passed methionine are lack of research, and it is necessary to conduct research in this area

Embodiment 1

[0021] A preparation method of rumen-passing protected folic acid: 40% folic acid, weigh the folic acid in the formula amount and mix it in a three-dimensional mixer for 30 minutes, put the folic acid in the tank mixer, add purified water in portions, stir for 15 minutes, put it into the extrusion out of the spheronizer for granulation to obtain the core material. After fluidized bed drying, the air inlet temperature is 50°C, and the drying time is controlled at 50 minutes to obtain a dry capsule core; coating: the above-mentioned dry core material is placed in a dry sprayer and sprayed with 60% rumen inert fat (palm oil) Sprinkle over the core. The rumen-protected folic acid used in the following examples is the product prepared by this method.

[0022] Determination of rumen-passing degradation rate of rumen-passing protected folic acid (microencapsulated coating treatment), 3 fistula cows were used in this experiment.

Embodiment 2

[0056] A preparation method of rumen-passing-protected folic acid: 45% folic acid, weigh the folic acid in the formula amount and mix it in a three-dimensional mixer for 30 minutes, put the folic acid in the tank mixer, add purified water in portions, stir for 15 minutes, put it into the extrusion out of the spheronizer for granulation to obtain the core material. After fluidized bed drying, the air inlet temperature is 50°C, and the drying time is controlled at 50 minutes to obtain a dry capsule core; coating: the above-mentioned dry core material is placed in a dry sprayer and sprayed with 55% rumen inert fat (palm oil) Sprinkle over the core.

Embodiment 3

[0058] A preparation method of rumen-passing protected folic acid: 35% folic acid, weigh the folic acid in the formula amount and mix it in a three-dimensional mixer for 30 minutes, put the folic acid in the tank mixer, add purified water in portions, stir for 15 minutes, put it into the extrusion out of the spheronizer for granulation to obtain the core material. After fluidized bed drying, the air inlet temperature is 50°C, and the drying time is controlled at 50 minutes to obtain a dry capsule core; coating: the above-mentioned dry core material is placed in a dry sprayer and sprayed with 65% rumen inert fat (palm oil) Sprinkle over the core.

Abstract

The invention belongs to the technical field of animal feeding and relates to rumen bypass protection folic acid, cow beverage containing the rumen bypass protection folic acid and application of the cow beverage. The rumen bypass protection folic acid (RPF) uses folic acid as core material and rumen inert fat as the coating, wherein the folic acid accounts for 40+ / -5% of the total weight of a coating tablet, and the rumen inert fat is palm oil. By adding the rumen bypass protection folic acid, cow milk output can be effectively increased, high milk protein and milk fat output are tend to increase. In addition the folic acid is tend to increase plasma glucose and decrease free fatty acid, beta-hydroxybutyrate and urea nitrogen concentration. The milk output can be increased evidently when the appropriate amount of 0.2g / day of rumen bypass protection folic acid is added. The milk output can be further increased when 0.2g / day of rumen bypass protection folic acid and 10g of rumen bypass methionine is added.

Description

technical field [0001] The invention belongs to the technical field of animal feeding, and relates to rumen-passing protected folic acid, cattle feed containing the rumen-passing protected folic acid and application thereof. Background technique [0002] Vitamins are necessary for the normal performance and health of dairy cows. Vitamins are divided into fat-soluble (vitamins A, D, E, K) and water-soluble (B vitamins and vitamin C) N categories. Vitamins A, D, and E are vitamins that must be added to dairy cow feed. Since bovine rumen microorganisms can synthesize vitamin K and B vitamins, and liver and kidney can synthesize vitamin C, generally, no additional addition is required except for calves. However, sufficient vitamin A, vitamin D and vitamin E must be provided in the diet to meet the needs of dairy cows and beef cattle in different physiological periods. However, with the improvement of the production level of dairy cows, more and more reports indicate that the ...
