- چکیده:
- چکیده انگلیسی: In this study, a new N3-Schiff base ligand (L) was obtained from via condensation reaction of diethylenetriamine and (Z)-3-(4-(dimethylamino)phenyl)acrylaldehyde (1:2 ratio). Then some its new five coordinated HgLX2 complexes inwhich X is halide/pseudohalide were synthesized. The ligand and its complexes were characterized by various analysis tools such as FT-IR, 1H and 13C NMR, UV–visible, thermal analyses and molar conductivity measurements. Based on the spectral data and conductivity measurements, all the newly prepared compounds were found to be non-electrolyte. Moreover some mercury complexes were prepared in nano-structured size by sonochemical method and confirmed by X-ray powder diffraction method (XRD) and scanning electron microscopy (SEM) analyses. The Schiff base and its mercury complexes have been screened for their in-vitro antibacterial activities (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis) and antifungal activities (Candida albicans and Aspergillus oryzae) using well diffusion method. Furthermore, thermal behaviors of ligand and its mercury complexes were evaluated in the range of room temperature to 1000°C under nitrogen atmosphere. The Schiff base ligand and complexes were decomposed completely via 2 to 5 thermal steps.

- چکیده:
- چکیده انگلیسی: This experiment was conducted to investigate the effects of olive leaf (OL) on the performance, abdominal fat pad and some ileal bacterial population of Cobb broiler chickens. A total number of 400 day-old chicks were randomly distributed into floor pens and reared under the same condition until 14 days of age. On day 14, each pen was randomly assigned to one of the five experimental treatments with four replicates of 20 male and female chicks. The dietary treatments were consisted of a control group which fed basal diet without OL entire period of the study and groups 2 to 5 that fed diets supplemented with 0.25, 0.50, 0.75 and 1.00% OL powder, respectively. On days 21 and 42 of the experiment, ileal digesta samples were collected under the sterile condition to evaluate ileal bacterial population. The results indicated that birds fed diets containing various levels of OL, had higher body weight gain (except for 1.00% OL) and lower feed conversion ratio compared to that of the control group. Dietary inclusion of OL resulted in a higher count of Lactobacillus sp. compared to the control group on 42 days of age, while Escherichia coli count significantly was not influenced. The abdominal fat pad was lower in birds fed OL supplemented diets. In conclusion, findings of the current experiment showed that the OL had positive effects on feed conversion ratio, abdominal fat pad deposition and ileal bacterial count of broiler chickens.

- چکیده:
- چکیده انگلیسی: The purpose of this study was to investigate the effect of different corn processing methods on rumen microbial flora, histomorphometry and fermentation in fattening male lambs. Twenty male lambs (average age and weight of 90 days and 25.00 ± 1.10 kg, respectively) were used in a completely randomized design including four treatments and five replicates each over 80 days long period: 1) Lambs fed ground corn seeds; 2) Lambs fed steam-rolled corn; 3) Lambs fed soaked corn seeds (24 hr) and 4) Lambs fed soaked corn seeds (48 hr). At the end of the experiment, three lambs of each treatment were slaughtered and samples were collected for pH, volatile fatty acids, amylolytic, proteolytic, cellulytic and heterophilic bacteria and protozoa assessment. The number of proteolytic bacteria in soaked corn seeds was significantly increased in comparison with other treatments. The thickness of wall, papillae and muscular layers of rumen in the soaked corn seeds treatment was significantly increased. Overall, from a practical point of view, soaked corn processing could be generally used in lambs fattening system.
