Embodiment 1

[0029] 1) The fermented broth of the alpine fermented mold is filtered with a plate and frame filter press to obtain wet cells with a water content of 57.8%. Take 100Kg of wet cells of Mortierella alpina, and use a sand mill to break the wall. The grinding medium uses zirconium beads. After the cells are ground, they flow out of the sand mill to obtain bacteria sludge with a particle size of 1-10 μm.

[0030] 2) Add 20Kg of maltodextrin, 12kg of sodium caseinate, 1.7kg of ascorbyl palmitate, 0.65kg of vitamin E and 50Kg of water for every 100Kg of wet bacteria. , ascorbyl palmitate, vitamin E and purified water, stirred evenly, and then ground with a sand mill to obtain the bacterial liquid.

[0031] 3) Spray-dry the bacteria solution prepared in the second step by using a pressure spray dryer, the feed pressure is 10-18 MPa, and the hot air temperature of the dryer is 150-185° C. to obtain bacteria powder.

[0032] 4) add thallus powder in the fluidized bed, take shellac acc...

Embodiment 2

[0034] 1) Take 50Kg of Mortierella alpina wet mycelium and 50Kg of Schizochytrium wet mycelium (filter the Schizochytrium fermentation liquid with a centrifuge), and use a sand mill to break the wall. The grinding medium uses zirconium beads. After the body is ground, it flows out of the sand mill to obtain the bacteria slime with a particle size of 1-10 μm.

[0035] 2) Add 18Kg of modified starch, 8Kg of lactose, 7Kg of maltodextrin, 10Kg of sodium ascorbate and 53Kg of water for every 100Kg of wet bacteria. The homogenizer performs homogenization on the bacterial liquid.

[0036] 3) Dry the bacterial liquid obtained in the second step by using an airflow spray dryer, first put 10 kg of maltodextrin into the material trolley of the airflow spray dryer, and heat the air at a temperature of 113-135° C. to obtain bacterial powder.

[0037] 4) Add bacterial cell powder into the material trolley of the coating drying tower, and add acrylic resin No. II as a rumen-passing protecti...

Embodiment 3

[0039] 1) Take 100Kg of wet bacterium of Wukenia, use a homogenizer to break the wall, the homogenization pressure is 35-62MPa, and the temperature of the feed liquid is kept at 65-72°C. The bacteria sludge with a particle size of 1-10 μm is obtained.

[0040] 2) Add sodium caseinate, solid corn syrup, phospholipids and purified water to the bacteria slime at a ratio of 1kg of sodium caseinate, 1kg of solid corn syrup, 0.5Kg of phospholipid, and 55Kg of water for every 100Kg of wet bacteria, and stir After uniformity, use a high-pressure homogenizer for homogenization.

[0041] 3) Dry the bacteria solution prepared in the second step by using a drum dryer, using 0.15-0.25 MPa steam during drying, and the temperature of the outer wall of the drum at 110-135° C. to obtain bacteria powder.

[0042] 4) Take polyvinyl alcohol acetate phthalate at a ratio of 20 parts by weight per 100 parts by weight of wet bacteria, and dissolve the polyvinyl alcohol acetate phthalate with water a...

Abstract

The invention relates to the technical field of livestock feeds, and discloses a feed for improving milk-fat percentage of ruminant and unsaturated fatty acid content in milk. The feed comprises a core and a shell, wherein the core contains microbial thallus, and the shell contains rumen protectant; the microbial thallus is subjected to wall-breaking processing. The thallus feed provided by the invention can protect grease and protein in the feed, so as to prevent the grease and the protein from being decomposed in the rumen of the ruminant, and improve the milk-fat percentage of the ruminantand polyunsaturated fatty acid content in the milk. The invention further provides a preparation method of the thallus feed, comprising the following steps: 1) performing wall-breaking processing on the microbial thallus to obtain the wall-broken microbial thallus; 2) covering the wall-broken microbial thallus with the rumen protectant. The method has the advantages that the process is simple, therumen prevention effect is good, and the processing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of livestock feed, in particular to a feed for increasing the milk fat rate of ruminants and a preparation method of the feed. Background technique [0002] The milk produced by ruminant cattle and sheep is rich in calcium, phosphorus, iron, zinc and other mineral elements. Its main components are water, protein, fat, phospholipid, and lactose. , its importance to human beings is increasingly accepted by the public; with the deepening of nutritional research, the quality requirements for milk and goat milk are getting higher and higher, and the quality of milk and goat milk is related to feeding conditions and feed quality. Highly correlated. On this basis, the improvement of feed technology for cattle and sheep has been promoted. [0003] Dairy cows, dairy goats, especially high-yielding dairy cows and high-yielding dairy goats are prone to insufficient energy intake during the peak milk production period...
