Abstract

The invention provides a rumen slow-release nutrition bar and a preparation method thereof. The problems that in the prior art, nutrient substances for preventing and treating ketosis and fatty liverof dairy cows in the perinatal period are poor in slow-release effect, and the ketosis cannot be prevented and treated are solved. The preparation method comprises the following steps: (1) respectively preparing choline chloride particles, calcium propionate particles and propylene glycol particles; (2) preparing a slow-release adhesive solution; and (3) fully mixing the three particles prepared in the step (1) with the slow-release adhesive solution prepared in the step (2), stirring at 80-90 DEG C for 5-10 minutes, carrying out injection molding to obtain a bar core, drying, cooling to roomtemperature, taking out, and spraying a layer of polyacrylic resin II on the outer surface of the bar core, thereby obtaining the product. By coating choline chloride, calcium propionate and propyleneglycol in proportion and adopting a slow-release treatment technology, the retention time of the two raw materials in rumen is prolonged, glycogen is provided for dairy cows, the liver burden of thedairy cows is reduced through choline, and the effect of preventing postpartum ketosis is achieved.

Description

technical field

[0001] The invention relates to the technical field of animal nutrition, in particular to a rumen slow-release nutrition bar and a preparation method thereof. Background technique

[0002] The peripartum period of dairy cows refers to the period from 3 weeks before delivery to 3 weeks after delivery. In order to adapt to the needs of parturition and lactation, the endocrine and metabolic systems of cows undergo tremendous changes during this period. The peripartum period is a key control point for dairy farm profits in the process of dairy cow breeding. During this special and critical period, its feeding management determines the milk production and health status of dairy cows throughout the lactation period. After the cows enter the peripartum period, the dry matter intake (DMI) gradually decreases, and reaches the lowest level at the time of delivery. Although the DMI of the postpartum cows gradually increases, the milk production peak of the cows is about...
