AB  - This study was carried to determine if dietary tryptophan can be beneficial for piglets in period of weaning. Trial was conducted on 84 individuals (Landrace×Yorkshire) female and castrated male piglets, at 30 days of age, and of 9.78±0.42 kg. Test subjects were penned into four groups and allocated to four different diets. This was done opposite to standard farm procedure; all piglets penned in same group came from different litters. Animals were fed ad libitum for six days. Piglets in trial groups were fed with basically same mixture with different levels of digestible L-tryptophan (0.1; 0.2; 0.3%). Productive performance (FCR; ADG; ADFI) was calculated and behavior characteristics (postures, mounting, abnormal and aggressive behavior) were observed using CCTV cameras. For the purpose of production performance analysis one way ANOVA was used while the Tukey test served to determine the statistical significance of the differences between individual means values. Considering that there is no normal distribution for behavioral parameters, we used non parametric Kruskal-Wallis test with multiple comparisons of mean rank between groups. Productive results showed that control group had significantly better results for average daily gain compared to all trial groups (p<0.05), other productive parameters didn’t show any significant difference. On the other hand, statistically significant results occurred for two behavioral characteristics. Fighting differed significantly (p<0.05), during first day of weaning between control and trial groups, intensive ear biting occurred at day two and three after weaning, and different significantly on day three (p<0.05). According to our results tryptophan had no positive effects on productive performance (feed intake, daily weight gain and feed conversion), but had some positive effects on reducing aggressive behavior. Conclusion could be that implementing small doses of tryptophan on weaning can be beneficial to reducing stress and behavioral anomalies of piglets. Further more extensive studies should be carried to verify these results. © 2021, Massimo Morgante. All rights reserved.

AB  - The first Co(III) complexes with (1,3-selenazol-2-yl)hydrazones as an unexplored class of ligands were prepared and characterized by NMR spectroscopy and X-ray diffraction analysis. The novel ligands act as NNN tridentate chelators forming octahedral Co(III) complexes. The impact of structural changes on ligands' periphery as well as that of isosteric replacement of sulphur with selenium on the electrochemical and electronic absorption features of complexes are explored. To support the experimental data, density functional theory (DFT) calculations were also conducted. Theoretical NMR chemical shifts, the relative energies and natural bond orbital (NBO) analysis are calculated within the DFT approach, while the singlet excited state energies and HOMO-LUMO energy gap were calculated with time-dependent density functional theory (TD-DFT). The electrophilic f(-) and nucleophilic f(+) Fukui functions are well adapted to find the electrophile and nucleophile centres in the molecules. Both (1,3-selenazol-2-yl)- and (1,3-thiazol-2-yl) hydrazone Co(III) complexes showed potent antimicrobial and antioxidant activity. A significant difference among them was a smaller cytotoxicity of selenium compounds.
