Embodiment 1

[0018] Provide rumen-passed choline coated with palm oil, which contains 10% lecithin, 10% palm oil, 35% white carbon black, and 45% choline;

[0019] The palm oil used therein is prepared as follows: the refined palm oil is heated to 65°C and then cooled to a range of 53.5-60.0°C.

[0020] The preparation method of palm oil coated rumen choline particles of the present invention comprises the following steps:

[0021] 1) Mix white carbon black and choline evenly in proportion;

[0022] 2) Fully mix lecithin and palm oil evenly;

[0023] 3) Add the mixture of step 1) to the oil of step 2) and mix to form a mixture;

[0024] 4) Stir the mixture processed in step 3) in 4 standard atmospheric pressure homogeneous tanks for 60 minutes;

[0025] 5) Use the material oil pump to transport the mixture in step 4) to the centrifugal granulator to make granules;

[0026] Add the prepared palm oil-coated rumen-passed choline granules to the feed of dairy cows for feeding, and the addi...

Abstract

The invention provides palm oil coated rumen bypass choline for the lactation period of dairy cows. The palm oil coated rumen bypass choline comprises 10% of lecithin, 10% of palm oil, 35% of white carbon black and 45% of choline, wherein the palm oil is prepared by heating refined palm oil to 65 DEG C and cooling to 53.5-60.0 DEG C. The palm oil coated rumen bypass choline is used for prepared feed for the lactation period of the dairy cows. The palm oil coated rumen bypass choline has the advantages that the rumen bypass efficiency of the palm oil coated rumen bypass choline can reach 96%, the particle size of the palm oil coated rumen bypass choline is smaller than 0.80mm, and the dissolution rate of methionine in small intestines can reach 95%; the palm oil considers the comprehensiverequirements on various fatty acids of the dairy cows, and the problems of metabolic disorders caused by choline shortage in the lactation period of the dairy cows and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of dairy cow feed components, and in particular relates to palm oil-coated rumen-passed choline used in the lactation period of dairy cows. Background technique [0002] Cows need choline, a precursor to acetylcholine, to form certain phospholipids in their body. Choline acts as a methyl donor to synthesize fat in the liver, which is then exported from the liver as an energy source. The threat of developing a fatty liver is thus reduced. Adding rumen-protected choline to the diet can promote lactation of dairy cows, increase milk production, and possibly increase milk fat percentage. Therefore, in order to achieve and maintain high quality and high yield, the addition of choline becomes necessary, especially in the early stage of lactation. In order to prevent choline from being decomposed in the rumen and ensure that it is absorbed in the digestive tract after the rumen, rumen-protected choline should be...
