A 16-week trial evaluated the effects of ethanolic extract of Aspiliaafricana leaf (EeAaL) on the growth performance, carcass and egg characteristics of growing and laying quails. One hundred and eighty (180), one-week old Japanese quail chicks were assigned to six experimental diets (0, 2.5, 5, 7.5, 10% EeAaL or 0.02% oxytetracycline). Each treatment had 30 birdswhich were further subdivided into three replicates of 10 birds. Each replicate was housed in a pen under the deep litter system; feed and water were provided ad libitum.Growth performance and egg characteristics(egg quantity and quality) indices were subjected to the one-way ANOVA in a completely randomized design (CRD). No significant (P>0.05) effect of EeAaL was observed between treatments on the final body weight and daily weight gains of quails. Feed conversion ratio (4.95 – 5.28) was significantly (P<0.05) improved in quails fed 2.5 – 7.5% EeAaL diets. Zero mortality was observed in quails fed 5 – 10% EeAaL diets compared to other treatments. EeAaL supplementation reduced (P<0.05) the amount of fat deposition in quail carcass, thus improving the carcass quality. The efficacy ofEeAaL was more pronounced in laying than growing quails where significant (P<0.05) differences were observed on some external and internal egg characteristics, whereas egg composition did not differ (P>0.05) between treatments. Egg number, hen day production, albumen weight,yolk weight, shell thickness and yolk colour were significantly improved following dietary EeAaL  upplementation, indicative of strong growth promoting and stimulatory effects.Therefore, for improved carcass and egg performances up to 7.5% EeAaL shoud be supplemented intoquail diets.Keywords: Leaf extract, growth rate, egg characteristics, bush marigold, quails

Depuration is an effort to reduce/eliminate contamination including microplastics, which one is using a water circulation system. This study aims to determine the effective depuration time to reduce the microplastic content in Asaphis detlorata This study used a quantitative approach with experimental research design with a completely randomized design. There are 450 shells used as an experimental animal where is the treatment consisted of four depuration times, namely 1;2;3; and 4 days with 3 repetitions of each treatment, while the control shells were without depuration. Analysis of variance (ANOVA) was used to see the effect of depuration treatment on the microplastic content. If the effect of the treatment was significantly different, then the post hoc test was continued to determine the differences between treatments. The results showed that Asaphis detlorata obtained from the mouth of the Lakatong river estuary were contaminated with microplastics ranging from 0.6 to 8.1 MPs/shellfish and an average of 3.96 MPs/shellfish. Depuration time significantly affected the microplastic content in shellfish depuration effectiveness. There is a tendency that the longer depuration time is decreased microplastic content in shellfish. The effective depuration time to reduce the microplastic content in Asaphis detlorata was 3 and 4 days. Further research is needed for a more effective depuration for cleaning microplastics in shellfish.

SummaryThe main aim of this research was to compare differences in heart rate values (HR) of soccer players during small-sided games (SSGs) with different number of players. We assumed that the number of “neutral” player or players in small-sided games will significantly affect the intensity of SSGs and in this case the heart rate values of participating players. The experimental group consisted of older junior players from the FC DAC 1904 Dunajská Streda soccer club (n = 9). The heart rate values were evaluated on the basis of collected data, which we obtained using Polar sport testers and special software Polar Team2. In order to find out the statistical significance of the difference in heart rate was used the One-Way ANOVA and the Bonferroni post hoc test. The level of statistical significance we set at 5 %. We found out that with increasing number of “neutral” players’ the intensity of small-sided games gradually decreased. During SSG1 (3 vs. 3), we recorded the highest achieved average heart rate values of the monitored players, in average 171.33 ± 9.39 beats.min-1. This form of the SSGs was the most intense, but not statistically significant. Our recommendation is to employ SSGs in the systematic training process with different number of players, because we can adequately prepare the players for the match load itself. Attention need to be paid for the playing position requirements.
