Effect of condensed tannins concentrations on protein degradability of red clover, Italian ryegrass and their mixtures
(Institute for Animal Husbandry, Belgrade-Zemun, Serbia, 2023-10-04) Marković, Jordan; Zornic, Vladimir; Štrbanović, Ratibor
Growing grasses in a mixture with legumes leads to more profitabl production, better quality of forages, an increase in soil biogenicity and fixation of a significant amount of nitrogen. The experiment was established as a two factorial
trial by the method of randomized complete block design in three replications. Italian ryegrass – monocrop (IR), red clover – monocrop (RC) and their mixtures – IR:RC (15:5 kg ha-1), IR:RC (15:10 kg ha-1), IR:RC (20:5 kg ha-1) and IR:RC (20:10 kg ha-1) were planted in November 2016, with the first cutting in the spring 2017 – on May the 9th, and the second cutting in the early summer – on June the 22nd. Theaim of this study was to investigate the concentrations of phenolic compounds such as condensed tannins in Italian ryegrass, red clover and their mixtures, as well as their concentrations impact on protein degradability in the rumen depends on the seeding rate in the mixtures and harvested in the spring and early summer. Results obtained in this study showed that higher concentrations of non-protein nitrogen and soluble protein in forages harvested in the spring influenced higher rapidly degradable protein concentration in investigated mixtures. The highest rumenundegradable protein was determined in Italian ryegrass monocrop harvested inearly summer, and we assume that high condensed tannins concentrationinfluenced the slower protein degradability. Our recommendation for plan breeders is that cultivars with higher content of condensed tannins should becreated and introduced in animal nutrition.
Nutritive value of field pea - oat and common vetch - oat bicrops
(National Library of Serbia, 2023) Marković, Jordan; Milenković, Jasmina; Petrović, Mirjana; Zornic, Vladimir; Racić, Nedeljko; Stepić, Marija; Blagojević
Peas and vetches are the most important plant species for the production of
forages, where they can be used as hay, haylage or silage. Due to their
specific characteristics - tendency to lodging and high buffering capacity,
they are usually grown in a mixture with small grains as support crops to
prevent or reduce lodging, reduce buffering capacity, and at the same time
obtain biomass suitable for the ensiling process. In pure crops, peas are
most often used as green feeds or hay at the stage of first pod formation,
while the best quality of vetch dry matter has been achieved by using it at
the stage of full flowering or the beginning of first pod formation, when up
to 25% of crude protein is obtained in the biomass of pure culture. The
nutritive value of pure crops of peas, common vetch and oats, and their
mixtures is presented as a function of the structure of the mixtures and the
stage of use. Special attention is paid to the content of cell wall
components and the dry matter digestibility of these feeds. Because of all
of these mentioned above, it is particularly important to choose the right
harvesting time to balance the yield and nutritional value of feeds used in
bicrops.
Antioxidant Activities, Total Phenols, and Proanthocyanidin Changes during Storage of Fourteen Faba Bean (Vicia faba L.) Populations from Serbia – A Chemometric Approach
(Informa UK Limited, 2023-06) Mitic, Violeta; Nikolić, Jelena; Andjelković, Snežana; Petrović, Mirjana; Stankov Jovanovic, Vesna; Milenković, Jasmina
Considering the interest in the consumption of faba bean and study of antioxidants in natural food resources, methanol extracts of fourteen Vicia faba cultivars harvested from a two-year field experiment were studied for their phenolic compounds, proanthocyanidines, and antioxidant activities by the DPPH free radical scavenging assay, ABTS cation radical decolorization assay, ferric reducing antioxidant power (FRAP), cupric reducing antioxidant capacity (CUPRAC), and total reducing power (TRP). The results indicate significant differences among the populations in their content of polyphenols and proanthocyanidine, resulting in variations in antioxidant activity of seed extracts. The storage of V. faba mature seeds under uncontrolled, but identical conditions decreased the total phenol content and antioxidant properties. The total phenols were from 10.12 ± 0.19 to 18.53 ± 0.14 mg GAE g−1 DE (2021 year) and 19.52 ± 0.16 to 26.94 ± 0.34 mg GAE g−1 DE (2022 year). In the 2022 growing season, the DPPH free radical scavenging activity had higher values for all populations from 4.83 ± 0.002 to 6.17 ± 0.003 g mg TE g−1 DE. Hierarchical cluster analysis and principal component analysis obtained from antioxidative profiles grouped the samples into two major clusters. The first cluster consists of extracts of V. faba cultivars from the 2021 growing season, while the V. faba cultivars from the 2022 growing season are in second cluster. Tested cultivars can be used as a readily available source of natural antioxidants.
Susceptibility of grapevine cultivars to Eutypa lata in Serbia
(Uniwersytet Przyrodniczy w Lublinie, 2023-08-31) Živković, Sanja; Vasic, Tanja; Marković, Jordan; Jevremović, Darko
The species Eutypa lata is one of the most critical phytopathogenic fungi that presents a threat to vineyards by causing significant economic damage. This grapevine disease is hazardous because there is no adequate chemical protection, so after its progression, there is a decrease in yield and dieback of parts or whole infected shoots. There are also no grapevine cultivars resistant to this disease. For these reasons, in this paper, testing of the susceptibility of a pair of grapevine cultivars to this disease was carried out. The testing was performed under semicontrolled conditions and included six of the most economically essential grapevine cultivars in Serbia (Riesling italico, Cabernet Sauvignon, Cardinal, Rkaziteli, Pinot noir, and Prokupac). Testing was performed using 14 isolates of E. lata isolated in Serbia and two control isolates obtained from the INRA. For specific detection of isolates of Eutypa spp. included in the experiment, a specific pair of primers, Lata 1/Lata 2.2, was applied, and an amplicon of the expected size of approximately 385 bp was established in all isolates. In the conditions of the set experiment, of all of the domestic and foreign-tested grapevine cultivars, the local cultivar Prokupac showed greater resistance to the isolates. In contrast, the cultivars Riesling italico, Cabernet Sauvignon and Cardinal, Pinot noir showed sensitivity to the isolates of E. lata, but not to the same extent as the cultivar Rkaziteli, which proved to be susceptible.
Variability of Meadow Fescue Accessions and Productivity and Quality of their Polycross Progenies
(Institutul Național de Cercetare Dezvoltare Agricolă Fundulea, 2023) Babić, Snežana; Sokolović, Dejan; Radović, Jasmina; Andjelković, Snežana; Lugić, Zoran; Petrović, Mirjana; Zornic, Vladimir
The collection investigated included nineteen meadow fescue accessions, 16 wild populations, and 3 commercial cultivars. The first part of the experiment was performed in a plant nursery at a distance plant of plant 60x60 cm. The experiment was done as a randomized block design with 30 plants per accession. This part of the experiment aimed to determine values and variability for the studied traits (heading date, plant height, length of leaf and the number of generative and vegetative tillers per plant and dry matter yield per plant) in two productive years. Data processing was done by ANOVA analyses. The obtained results show that the studied accessions had significant within and among variability for all parameters. The number of generative tillers per plant, plant height and leaf length positively affected dry matter yield per plant. The highest dry matter yield per plant was observed for accessions: FP 1 and FP 4, but the best ratio between dry matter yield and number of vegetative tillers per plant, traits that influenced dry matter quality, was scored for accessions FP 8, FP 7, FP 3, FP 10 and FP 16. The second part of the trial investigated the productivity and biomass quality of the best 26 progenies selected from the polycross field and formed from the plant with the best performance from the nursery. They are tested in plots 5x2 m, as a randomized block design, in 3 replications. The most productive progenies with high biomass quality originated from accession FP 8, FP 3 and FP 13.
