A kind of compound fat powder and its preparation method and application in ruminant feeding

Abstract

The invention discloses composite fat powder. The composite fat powder is mainly prepared from fat powder, a microelement compound and an oil-soluble emulsifier, and can provide microelements and grease needed by animals, avoid dyspepsia and diarrhea, reduce stress, improve feed palatability, increase feed intake, solve the problem of energy deficiency and obviously promote growth and increase milk production. The invention further discloses a preparation method and application of the composite fat powder. The preparation method is unique in process, easy to implement and short in production cycle; the fat powder can be rapidly dissolved in water after being subjected to high-pressure homogenization to form fine particles, the fine particles disperse rapidly after passing through the rumen of ruminant animals to make full contact with the inner wall of the digestive tract, and thus the digestion and utilization rate of fat is significantly increased; the compound fat powder can be directly added into drinking water and taken by animals at any time, the compound fat powder does not need to be mixed with concentrated feed or premix or fine supplementary feed in use, damage caused by the external environment (heat, light, water and the like) to effective ingredients can be reduced, and deterioration and loss can be avoided.

Description

Technical field [0001] The invention belongs to the field of feed processing, and particularly relates to a composite fat powder, a preparation method thereof, and application in ruminant feeding. Background technique [0002] Ruminant fat powder is an energy source that does not affect rumen fermentation and is easily digested, absorbed and utilized by the digestive system behind the rumen. Ruminants mainly deposit fat during the fattening period, especially in the late fattening period. However, as the fattening time is delayed, the daily weight gain decreases. In order to pursue high weight gain, it is necessary to increase the energy concentration of the diet, and generally increase the feeding amount of corn. But it is easy to cause acidosis. Rumen bypass fat powder has high energy and low heat consumption. Adding it to the diet during the fattening period can increase the energy concentration and total energy intake (especially in summer), and has obvious effects on increa...

AI Technical Summary

Problems solved by technology

It can be seen that it is time-consuming and labor-intensive to add fat powder to the concentrate

And the fat powder is oil, affected by high humidity and high heat in the processing process, it is easy to oxidize and deteriorate, and the shelf life of its concentrated supplement is also short

The second method: the fat powder is sprinkled on the forage. Affected by the feeding method, there are many uncertain factors, and uneven feeding, over-feeding, and under-feeding may occur, which is not conducive to management.
