Heat score accessed with aid of tail-chalk influences pregnancy rate of suckled Bos indicus beef cows subjected to P4/estradiol TAI-based protocols. Repositório Alice
SILVA, K. C.; RODRIGUES, W. B.; SILVA, A. S.; SILVA, J. C. B. da; ABREU, U. G. P. de; BATISTA, D. S. do N.; ANACHE, N. A.; BEZERRA, A. O.; JARA, J. do P.; NOGUEIRA, E..
It is known that cows that express estrus submitted to TAI protocols, have better pregnancy rates (Borges et al. 2011). So the goal was to test alternative to visual estrus observation, evaluating the effect of estrus expression with the assistance of tail-chalk on pregnancy rates and the pre-ovulatory follicle diameter in beef cows submitted to TAI protocols with use of two ovulation inducers: estradiol benzoate (EB) and estradiol cypionate (ECP).

Trametes versicolor growth and laccase induction with by-products of pulp and paper industry Electron. J. Biotechnol.
Rebelo Barreto Xavier,Ana Maria; Mora Tavares,Ana Paula; Ferreira,Rita; Amado,Francisco.
The cultivation of Trametes versicolor for laccase production and cell growth were strongly dependent on experimental conditions namely physical and chemical parameters as well as nutrient availability and inducer stimulation. Biomass growth was compared for a rich medium and for a defined medium in two different temperatures. The best temperature was 28ºC and the maximum specific growth rates were µmax = 0.083 h-1 for the rich medium and µmax = 0.043 h-1 for the defined medium. It was clearly shown that laccase production is not associated with cell growth, indicating that this ligninolytic enzyme must be produced in the defined medium by a secondary metabolism. In order to obtain laccase induction, addition of solid lignin, lignosulphonates, veratryl...
