Polypeptide and microbial preparation for improving ox myotendinous development and its production

Abstract

A polypeptide and microbial feed additive for improving beef muscle belly connective tissue synthetic function is safe and non-toxic. The process is carried out selecting natto rod, lichenized bacillus, plant lactobacillin, cheese lactobacillin and beer yeast, independent or composite culturing to obtain composite bacterium, naturalizing while expansion culturing, solid fermenting with culture medium and aseptic water, fast low-temperature drying by drier, adding into special carrier, crushing and screening to obtain final product. It obtains high-concentration enteric beneficial microbial pool and mixtures of health-care soybean peptide, oligo-peptide and short peptide containing natto-kinase. It's practical and economical, and it tastes good and can improve digestion-absorbing function of beef for protein in feed.

Description

technical field

[0001] The invention relates to a feed additive for microorganisms and short peptides in the feeding of special fat cattle. By adding them to beef cattle feed, special microorganisms and various metabolites such as soybean short peptides and soybean fibrin are used to promote the digestion and absorption of fat cattle The function improvement, especially the increase of tendon protein content of beef cattle, and the improvement of meat palatability and nutritional value belong to the technical field of agricultural biological products. Background technique

[0002] The English word for "fat cow" is beef in hotpot, literally translated as "beef eaten in a hot pot". It is not a breed of cattle, nor is it simply fattened and slaughtered, nor is it fattened. Usually, the high-quality longissimus dorsi and abdominal boneless muscles are selected to be trimmed and formed. After maturation and deacidification, the parts that are sliced ​​into thin slices and eaten ...
