Colostrum is a rich source of nutritional and non-nutritional components recognized as essential to transfer passive immunity newborn calves. Because the individual seasonal variability in colostrum yield composition, maintaining an adequate supply high-quality year-round remains challenge for commercial dairy producers. In this narrative review, we described individual, seasonal, herd-level production summarized association between animal factors such parity, sex calf, calf birth weight, well indicators cow's metabolic status composition colostrum. Further, reviewed current knowledge on influence prepartum nutrition management strategies production. Research metabolizable energy protein supplied diet into inclusion vitamins, minerals, feed additives suggests influences yield, quality, Furthermore, environment dry period length remain influential However, additional research needed understand mechanisms by which affects Lastly, time harvest oxytocin administration effect heat-treatment storage colostral were discussed.

Bovine colostrum provides newborn calves with strong passive immunity, which will further affect the immunity of their offspring. Compared other commercial dairy products, bovine emphasizes limit aflatoxin M1, pathogenic bacteria, microorganisms, antibiotics, stimulants, and items, so it is safe to use. There are many reports that use as a breast milk fortifier for preterm infants necessary immune support premature infants, but selection products chosen must be free Bacillus cereus because they very dangerous infants. This also used in more clinical research needed. At same time, should emphasized composition BC different from human colostrum, particular, main protein casein, while whey protein, especially α-lactalbumin, together ovalbumin still reference best biological value, muscles.

Enterococci are widely distributed in dairy sector. They commensals of the gastrointestinal tract animals, thus, via fecal contamination, could reach raw milk and products. The aims this study were: 1) to investigate enterococcal diversity cow feces samples 2) evaluate antibiotic resistance (AR) dairy-related enterococci their ability transfer genes. E. faecalis (59.9%), faecium (18.6%) lactis (12.4%) were prevalent milk, while (84.2%) hirae (15.0%) dominant bovine feces. RAPD-PCR highlighted a high number Enterococcus biotypes (45 from 37 feces) none strains exhibited genetic profiles similar those biotypes. A percentage isolated (71%) identified as multidrug resistant against streptomycin tetracycline widespread among commonly linezolid quinupristin/dalfopristin.

We performed a series of tests to verify the capacity and safety bacterial isolate. These included evaluation hemolytic capacity, cytotoxicity, antimicrobial susceptibility, tolerance adverse conditions, survival gastrointestinal tract, antagonistic activity against pathogenic bacteria, auto- co-aggregation abilities. The results demonstrated no activity, microorganism did not exert cytotoxic effect on Madin-Darby Bovine Kidney cells. It was observed that Lsc.CB054 susceptible nine (9/10) antimicrobials tested, showing resistance only sulfonamide. When subjected various acidic bile salts, phenol, rate ≥ 8 log CFU/mL.
