The application discloses a bacteriostatic type of liquor dreg containing Zhangzhou Bacillus GBW-NX and a preparation method and application thereof, and belongs to the technical field of microorganisms. The preservation number of the Zhangzhou Bacillus GBW-NX is CGMCC No. 27402. It is proved through experiments that the Zhangzhou Bacillus GBW-NX has the bacteriostatic effect on inhibiting Escherichia coli, Salmonella and Staphylococcus aureus. The Zhangzhou Bacillus GBW-NX is placed in a solid culture medium containing the liquor dreg to be fermented and enzymolyzed to prepare the bacteriostatic type of liquor dreg. The bacteriostatic substance of the bacteriostatic type of liquor dreg is a bacteriocin. It is also proved that the bacteriostatic type of liquor dreg can improve the intestinal function of ruminants including lactating cows, and can also improve the milk yield of the cows, thereby widening the application range of the Zhangzhou Bacillus GBW-NX, providing a new direction for the feeding of ruminants, and having important significance for the breeding of ruminants.

The present application relates to the field of microbial technology, in particular to bacillus subtilis BS-1 and its application in water buffalo silage feed, the strain BS-1 of the present application has good bacteriostatic activity on escherichia coli, salmonella and streptococcus uberis, after mixing and fermenting according to a specific proportion with orange peel and cassava residue, the bacteriostatic spectrum of the obtained silage feed is significantly enhanced, which can simultaneously inhibit escherichia coli, campylobacter jejuni, salmonella, streptococcus uberis, staphylococcus aureus and streptococcus agalactiae that cause diarrhea and mastitis. In the feed, after mixing 60%-75% of orange peel and 25%-40% of cassava residue, the crude protein content of the fermentation product is significantly improved, and the fiber content is reduced. Feeding test shows that the feed can significantly improve the milk yield and milk quality of lactating water buffalo, and effectively alleviate diarrhea. The present application provides a safe, efficient and nutritious silage feed with disease prevention function.

The present invention is in the field of feed additives for animals, e.g., farming animals, in particular feed additives to be added to animal feed to effect an improved performance, e.g., an increasing feed intake, increased average daily gain, increased feed efficiency (i.e., decreased feed conversion ratio), and / or increased milk yield, of such animals.

This invention belongs to the field of animal husbandry and veterinary medicine technology, and discloses the application of rumen-exposed taurine in regulating the production performance and immune capacity of peripartum dairy cows. This invention discovers that rumen-exposed taurine can significantly regulate inflammatory responses, oxidative stress, and energy metabolism-related indicators in peripartum dairy cows, thereby regulating immune function and metabolic balance, effectively improving milk yield, milk quality, and disease resistance. Experimental results show that rumen-exposed taurine can significantly reduce inflammatory responses in peripartum dairy cows, improve energy metabolism, and improve the levels of immune-related factors, thereby reducing the incidence of postpartum diseases and improving production efficiency. This invention reveals a new use of rumen-exposed taurine in the health management of peripartum dairy cows, providing a scientific basis for its development as a feed additive or veterinary preparation, and has broad clinical application prospects.

This document discloses methods and compositions for use in various therapeutic, preventive, and control measures comprising from about 0.00001% by weight to about 100% by weight of an extract derived from sugarcane. The therapeutic, preventive, and control measures involve administering the extract to a subject, the extract comprising from about 10 catechin equivalents (CE) g / L to about 50 CE g / L of polyphenols or from about 100 CE mg / g to about 500 CE mg / g of polyphenols. These therapeutic and preventive measures include antimicrobial activity, particularly against respiratory viruses in humans, and treatment of microsporidia infections, such as EHP in shrimp and prawns. Control measures include reducing methane production in ruminants. The use of these compositions in, for example, dairy cows improves cow health by minimizing mastitis while increasing milk yield.
