    Efeito do uso de cultura simbiótica no sucedâneo do leite sobre parâmetros hematológicos, bioquímicos, fecais e corporais de bezerros leiteiros
    (Universidade Brasil, 2021) Mancilha, Sheila Viviane de Souza; Soares, Vando Edésio
    Although dairy farming has developed a lot in recent years, the control of diarrhea in Holstein calves is still very difficult, since there is still a need for economic detachment for such control. The use of symbiotics has been widely studied and is a promising alternative in combination with antibiotics or alone. Re-establishing the gastrointestinal microenvironment improves absorption and increases the animals' immunity. This work was developed to evaluate the hematological, biochemical, fecal and body parameters of dairy calves that received a milk replacer containing a symbiotic culture of bacteria and yeast (CSBL) for a period of 30 days. The experiment was approved by CEUA under protocol 2000090. Twenty-four male Holstein calves were used, which, when properly colostrated on the day of birth, were taken to the experiment site. The calves were randomly divided into four distinct groups: a control group, a 0.5 g CSBL group, a 1.0 g CSBL group and another 2.0 g CSBL group. Every 15 days, blood samples were taken to assess hematological and biochemical parameters. The calves were weighed weekly and their body measurements were also measured (withers, rump and thorax). The group treated with 0.5 g and 1.0 g CSBL, showed greater weight gain and body performance, as well as better control of the consistency of their stools, which remained within normal and soft parameters, without diarrhea. The hematological and biochemical parameters showed mostly positive action to the use of CSBL. It is noteworthy that the concentration of CSBL 2.0 g had no or negative effect on the parameters observed in treated calves. The concentration of CSBL 0.5 g, in addition to providing a better yield, easy handling, results in an excellent cost-benefit ratio for the producer, acting positively in one of the diseases that most damage the dairy activity, diarrhea.

    Aspectos físico-químicos e microbiológicos do processo fermentativo da Kombucha
    (Universidade Brasil, 2022) Magno, Mara Paula; Soares, Vando Edésio
    Kombucha is a fermented beverege, prepared from the fermantation of green tea and or sweetened black tea (Camellia Sinensis), and in a symbiotic culture process called Simbiotic Culture of Bacteria and Yeast (SCOBY), at room or controlled temperatura. It is considered a probiotic drink that balances the intestinal flora and strengthens the imune system. Changes in physical and chemical parameters must be observed during fermentation in order to have a better concentration and production. Aiming to explore other areas of consumption, as well as the animal área, this research aims to find the best range of production of this SCOBY evaluating the dynamics and growth of SCOBY symbiosis in kombucha with diferent concentrations of tea and sugar. The growth in animal nutrition has led to the emergence of a new generation of products to help balance the microbiota of animals. Green tea leaves at concentration of 0,6%, 0,8% and 1,2% and crystal sugar at concentration of 6% and 8% were used as substrate resultingin six treatments with four replications of 200 ml each. In a BOD type germination chamber, it was incubated at a temperature of 27°C over a total period of 14 days, starting from day 0 of fermentation. The parameters of pH, brix, SCOBY weight and colony forming unit (UFC) were evaluated. Thus, it can be concluded that for the SCOBY weight parameters and UFC for the concentration a of 1,2% of green tea and 8,0% of sucrose is the most indicated, there was interaction providing SCOBY weight again. For the pH parameter, related to green tea the best concentration was 0,6% and 0,8% and with sugar substrate the best concentration was 8,0%. For the Brix parameter, with analog measurement, the values were very homogeneous, showing no variability between the readings taken in the different concentrations of green tea and sucrose.
