Description

Fat powder for promoting rapid fattening of piglets and preparation method and application thereof
Technical Field
The invention belongs to the technical field of pig feeds, and relates to fat powder for promoting rapid fattening of piglets, and a preparation method and application thereof.
Background
Roast suckling pigs and roast pigs are classical delicious foods in China, have the characteristics of golden yellow color, crisp skin, tender meat and rich fragrance, are popular among the masses, and are one of the requisite dishes for the festival every year. The raw materials for preparing the roasted suckling pigs and the roasted pigs are generally 15kg-50kg suckling pigs, and the pork has certain requirements on subcutaneous fat and flavor, so that the local pigs or the fragrant pigs with higher body fat are generally used as better food materials.
However, in the current pig raising system in China, most of raising is lean type pig species, the body fat is too low, and only one third of the body fat is low, so that the piglets commonly supplied in the market are not suitable for the quality requirements of the roasted suckling pigs and the roasted pigs, the taste and satisfaction of consumers are affected, and if the local pigs or the fragrant pigs are adopted for roasting, the raising period is long, and the cost is too high. In addition, in the current feed nutrition research, a nutrition system with the aim of feeding more than 110kg of pork pigs is mainly adopted, the growing and developing and skeleton stretching are adopted as nutrition targets in the stage of piglets, the fattening in the stage of piglets is regarded as a measure which can influence the post fattening and weight increasing efficiency to a certain extent, and the current feed products or technologies with the aim of fattening the piglets are relatively lacking.
Therefore, the development of the product capable of promoting the rapid fattening of the piglets, specially meeting the fattening requirement of the piglets, reducing the piglet source cost of the roasted and burned piglets and improving the meat flavor, is quite practical.
