Research regarding growing promoters in feed of poultry broilers to stimulate growing speed, food conversion, to maintain the chickens ' health state and to improve the carcass quality, is a practice often used at world level. In this context is also our study regarding utilization of FA growing bio-stimulator, based on B12 vitamin, which was utilised in feeding of poultry broilers. In the research were utilized 5 chickens ' batches each with 50 heads, mixed sexes, from which one control batch (Lc) and 4 experimental batches (LE1-LE4). Studied chickens were feed with complete mixed fodders specific for each growing period mentioning that into the mixed fodders for experimental batches was added a bio-stimulator obtained in the fabrication process of B12 vitamin, in variable doses: LE1-50 ppm, LE2—100 ppm, LE3-150 ppm and LE4-200 ppm. The aim of the study was to make a comparative analysis of the results obtained at cutting by males and females from those 5 experience batches. At the end of growing period, 42 days, were slaughtered 10 individuals (5f and 5Q) from each batch, and the resulted carcasses were cut in component parts (breast, lower thighs, superior thighs, wings and back). At the end was observed the fact that FA growing bio-stimulator had a good influence not only on the size of carcass but also on the other cut parts of it. So the breast weight was higher with 4.23-30.39% at males and with 1-30.39% at females; lower thighs weight with 11.62-34.72% at males and with 5.75-31.23% at females; superior thighs weight with 11.78-24.44% at males and with 5.59-11.55% at females; wings weight with 8.64-26.03% and with 11.34-28.69% at females, and back weight with 7.48-36.78% at males and with 3.79-18.58% at females. The best results were obtained for batch LE4. [ABSTRACT FROM AUTHOR]
