Since then, positive genetic progress in the population and some economic disorders (e.g. the input and output prices disproportion) appeared in the swine sector. The study aimed to revise index according to the current circumstances and further ensure the desired gain. In three index variants, the current, optimal, and adjusted trait proportion was assessed. Economic weights (EWs) of the breeding objective traits were applied in two alternatives to evaluate the index for future stable and deteriorated conditions. Under the current index construction and stable EWs, the favourable selection gain in piglets born alive (NBA) and slight extension of farrowing interval (FI) is indicated. The optimal index construction would result in a favourable gain of both traits in one breed. The adjusted index maintained the increasing litter size equal to the current index and achieved favourable gain in FI in both breeds. The same was true for deteriorated economic conditions except for the optimised index variant, where expected higher genetic progress in one breed. Nevertheless, this genetic gain was insufficient to compensate the declined EW of traits, and the overall financial benefit was almost half of those in stable conditions. For both alternatives of evaluated economic conditions, the current index should be revised in terms of a slightly higher proportion of FI to reach favourable genetic gain in both breeding goals.</p> Zuzana Krupová Eliška Žáková Emil Krupa Ludmila Zavadilová Nina Moravčíková Copyright (c) 2022 Zuzana Krupová, Eliška Žáková, Emil Krupa, Ludmila Zavadilová, Nina Moravčíková 2022-10-11 2022-10-11 25 3 Evaluation of water temperature in the Bocegaj brook and in the Kolíňany pond in terms of fish life <p>During 2014, water temperature of the Bocegaj brook and the Kolíňany pond and its impact on fish life were monitored. Water sampling was carried out at regular monthly intervals, in the period from January to October, from six sampling points. The four sampling points were located directly on the water surface of the pond, the last place being the outlet from the pond. In this time horizon, all four seasons alternated, which was also reflected in the change of the water temperatures. Depending on the time of sample collection, the lowest average values for the entire monitored period were recorded in the winter (January, February) and the highest in the summer months (June, July, August). The maximum values of water temperature depending on the sampling point during the monitored period were found in the open water area of the pond.</p> Jana Ivanič-Porhajášová Copyright (c) 2022 Jana Ivanič-Porhajášová 2022-10-03 2022-10-03 25 3 The effects of dietary supplementation of common mugwort (Artemisia vulgaris) meal on growth and excreted Eimeria spp. oocysts incidence in Dwarf Lop rabbit kits <p>The goal of the study was to evaluate the effect of dietary inclusion of common mugwort (<em>Artemisia vulgaris</em>) herb on selected growth and health traits of young dwarf rabbits. The mugwort species represent regular botanical species with proven favourable effects on health state of many animal species. However, a dietary effect of <em>Artemisia vulgaris</em> (AV) on health of dwarf rabbit genepool has not been studied yet. The study was performed on a total of 12 kits of the Dwarf Lop breed. These kits were divided into 2 groups (control, C; experimental, E). From the age of 21 days up to the age of 112 days the kits in the experimental group received a&nbsp;complete diet specifically designed for the dwarf rabbits with 10% supplementation of the AV meal. There was found no significant adverse effect on live weight and average daily weight gain in rabbits of the E group. Concerning the anticoccidial effect, the 112-day-old rabbits fed the E diet showed a significantly lower (<em>P</em> &lt;0.05) number of excreted oocysts (1,766 OPG) as compared to those in the C group (6,845 OPG). Based on the results of the present study, there can be suggested that 10% dietary inclusion of the AV meal represents a safe share and it showed a positive effect on the excreted coccidiosis count in dwarf rabbits. However, it would be suitable to perform further studies, when the optimization of a mugwort dietary level during specific life periods of dwarf kits and the selection of other <em>Artemisia </em>botanical species will take a place. In addition, monitoring of more growth traits and biological effects of particular substances contained in <em>Artemisia sp. </em>would be studied on dwarf pet rabbits as well.</p> Lenka Kudělková Copyright (c) 2022 Lenka Kudělková 2022-10-03 2022-10-03 25 3 Effects of ginger meal supplementation on performance and meat antioxidative enzymes of broilers fed monosodium glutamate <p>The ameliorative effects of ginger meal (GM) on the performance, carcass, and meat qualities of broilers fed diets containing MSG were examined. A total of 360 day – old broilers were randomly allotted into four diets: Diet A (control), Diet B (basal + 1.25 g MSG/kg diet), Diet C (Diet B + 1.25 g GM/kg diet) and Diet D (diet B +&nbsp; 2.50 g GM/kg diet). The birds were fed starter and finisher diets and water <em>ad – libitum</em>. At 6 weeks old, growth performance, carcass and meat qualities were assessed. Broilers on Diets B to D significantly (<em>P</em> &lt; 0.05) recorded increased weight, feed, energy, and protein intakes with those on Diet D having the best feed conversion ratio. The dressed weight and dressing percentage of broilers on the experimental diets were better than the control diet. The inclusion of GM significantly (<em>P</em> &lt; 0.05) ameliorated the negative impacts of MSG on relative weights of the heart, liver, and bile. Meat catalase and glutathione peroxidase were significantly (<em>P </em>&lt; 0.05) reduced while lipid peroxidation and meat cholesterol were significantly (<em>P</em> &lt; 0.05) elevated among the birds fed Diet B when compared with the control. However, the inclusions of GM played a restorative role by significantly (<em>P</em> &lt; 0.05) improving the meat antioxidant enzymes and reducing lipid peroxidation and cholesterol. Therefore, the inclusion of MSG at 1.25 g/kg with an inclusion of 1.25 to 2.50 g GM/kg was beneficial for feed palatability enhancement with resultant improvement on performance, carcass, and meat qualities.</p> <p><strong>Keywords: </strong>Chicken, Carcass quality, Ginger, Haematology, Lipid peroxidation</p> Olumuyiwa Joseph Olarotimi Copyright (c) 2022 Acta Fytotechnica et zootechnica 2022-10-03 2022-10-03 25 3 Effect of feeding frequency of curcuma longa supplemented diets on nutrients intake, growth performance and rumen fermentation characteristics of goats <p>Natural feed additives are gaining increased attention due to their ability to improve animal performance. Hence, this study was carried out to determine the effect of feeding frequency of diets supplemented turmeric (Curcuma longa) rhizome powder on goats’ performance. Thus, a basal diet was formulated such that 10g of turmeric rhizome powder (TRP) was supplemented with 300g feed as ration for goats. Twenty goats were used for this trial, balanced for weight, arranged in Completely Randomized Design experiment, of five goats per group. The goats were fed the ration once a week, alternate days/skip a day, daily while the control had no TRP in their diet. The feeding trial lasted 56 days. Parameters were taken on nutrients intake, utilization, weight change, microbial evaluation, rumen fermentation characteristics and all data generated were subjected to statistical analysis. From the results, TRP supplemented diets did not significantly (P&gt;0.05) influence the nutrients intake except for crude protein intake (CPI). Nitrogen retention (NR), daily weight gain (DWG) and feed conversion ratio (FCR) were significantly (P&lt;0.05) influenced. NR (86.64%), DWG (55g/d) and FCR (9.96) of goat-does fed TRP supplemented diets on daily basis was the best. Feeding frequency of TRP supplemented diet linearly decreased total bacteria count (TBC) and rumen pH, as the frequency increases while total fungi count (TFC) non-linearly increases. Meanwhile, total volatile fatty acids (TVFA) did not follow a particular trend. Conclusively, daily supplementing of goats’ diet with TRP at 10g/300g feed optimally improved goats’ performance and is thus recommended.</p> Oluwatosin Bode Omotoso Adeyinka Alice Adebisi Bidemi Olufemi-Amodu Adebowale Noah Fajemisin Copyright (c) 2022 Dr. Omotoso, Oluwatosin Bode, Adebisi Adeyinka Alice, Olufemi-Amodu, Bidemi, Professor Fajemisin, A.

Identifying reliable selection traits that sustain plant growth and productivity under water-deficient conditions is essential for releasing resilient drought tolerant wheat genotypes. Herein, in order to identify the best combination of drought tolerance related-traits, this study was carried out to assess the effect of 21 shoot and 17 root secondary traits on grain yield of 40 bread wheat genotypes from germination to maturity stages under laboratory, greenhouse and field conditions. In this research, germination rate (GR), mean germination time (MGT), roots weight (RW), roots number (RN) and Root : Shoot ratio (R/S) were relevant for discriminating drought tolerant genotypes, expressing negative moderate correlation (r~-0.5) and explaining a significant part of yield variation (8 to 30%). Grain number (GN) was the most important agronomic trait (r~0.70-0.94) which explained up to 88 % of yield variation. This latter effect is reinforced by the indirect effects of productive spikes number (FSN), thousand kernel weight (TKW) and grains number per fertile spike (GNFS). The biomass (BY), ground cover (GC), spike (SL) and pedoncule lengths (PL) were also relevant, especially under severe stress (r=0.4-0.6 ; β=0.33-0.40) ; while the canopy temperature depression (CTD) was determinant under moderate stress (r=-0.45 ; β=-0.46). Combined selection for these traits will be effective to improve the process of developing high-yielding bread wheat varieties adapted to drought prone areas.</p> SAHAR BENNANI Nasserelhaq Nsarellah Ahmed Birouk Copyright (c) 2022 SAHAR BENNANI, Nasserelhaq Nsarellah, Ahmed Birouk 2022-10-03 2022-10-03 25 3 Effect of different mowing intensities on phytomass production of permanent grassland in a warm and an arid region <p>The aim of the work was to analyse the impact of different intensities of grassland exploitation on the productive capacity in the context of declining livestock numbers and the need for temporary or permanent extensification. The research was carried out in 2017-2020 in the locality of Žirany in the Nitra district, located in the temperate zone at the boundary between the continental and Atlantic-continental regions. Average annual temperatures are around 9 °C. The original semi-natural vegetation has been used for sheep grazing for many years. There were 8 experimental variants of use/cutting with different intensity of exploitation: var. 1 - abandoned unused, var. 2 - 3x per year, var. 3 - 2x per year, var. 4 - 1x per year, var. 5 - 4x - 3x - 2x - 2x - 1x per year, var. 6 - 1x - 2x - 3x - 4x per year, var. 7 - 3x - 1x - 1x - 3x and var. 8 - 2x - 1x - 1x - 1x - 2x. By comparing the sum of yields for the entire 4-year annual cycle, we concluded that, with the exception of the 1x annually mowed variant, all the others differentiated themselves from the abandoned stand by their increased production capacity. We also observed differentiation between fertilized and exploited variants into groups. The stand mowed 3 times annually (variant 2, 29.07 t ha<sup>-1</sup>) was shown to be the most productive. The second group consisted of variants with production lower in the sum of 4 years by about 5 t ha<sup>-1</sup> (3, 5, and 6). The same level of lower yield was then found on stands with temporarily reduced intensity of use (variants 7 and 8). In the effectiveness of applied nutrients on production growth, it was found that as the number of applications increased, nutrient use also increased. The average of the years in the overall assessment of the 4-year cycle showed the dynamics from the individual years and also confirmed the tendency of the highest nutrient use at a stable 3-cut use.</p> Ľuboš Vozár Miriama Lukács Peter Kovár Peter Hric Copyright (c) 2022 Ľuboš Vozár, Miriama Lukács, Peter Kovár, Peter Hric 2022-10-03 2022-10-03 25 3 Assessing the critical period of weed interference in groundnut Arachis hypogaea L. in Ogun State, south western Nigeria <p>The critical period of weed interference in groundnut was investigated in 2018 and 2019 early cropping seasons at the Federal University of Agriculture, Abeokuta, Ogun State, Nigeria. The experiment consisted of ten treatments arranged in a randomized complete block design and replicated three times. Treatments includes keeping plots weed free initially for 3, 6, 9, 12, 15 weeks after planting (WAP) and keeping plots weed infested initially for 3, 6, 9, 12, 15 WAP. Data collected on weed cover score, weed dry matter production, crop vigour score, canopy spread, pod yield and numbers were subjected to analysis of variance and treatment means were separated using least significant difference at P ≤ 0.05. The results showed that total weed dry matter production increased with weed infestation period and decreased with weed free period. Also, there was significant increase in pod yield and count when plots were kept weed free for 6 WAP and more. Our findings showed that, the highest percent weed accumulation, weed removal, pod yield loss and pod yield gain all occured between 3 and 6 WAP. Therefore, the critical period of weed interference in groundnut is between 3 and 6 WAP. Also, there was 83.4% pod yield loss in groundnut when weed was allowed to compete freely with the crop throught crop life cycle.</p> Samuel Osunleti Ayodeji Ajani Opeyemi Olaogun Temitope Osunleti Elizabeth Olatunde Copyright (c) 2022 Samuel Osunleti, Ayodeji Ajani, Opeyemi Olaogun, Temitope Osunleti, Elizabeth Olatunde 2022-10-03 2022-10-03 25 3 Garden pea yield and its quality indicators depending on the technological methods of growing in conditions of Vinnytsia region <p>This paper aims to study the growth and development of garden pea plants when liming the soil, applying mineral fertilizers, pre-sowing seed treatment with inoculants, micronutrients and foliar nutrition. Plants survival was higher in the trial variant when applying lime (1.0 norm of lime per ha), mineral fertilizers, pre-sowing seed treatment with Rhizobophyte and microfertilizer Wuxal Extra CoMo, foliar nutrition with microfertilizers Wuxal Microplant at the microstage ВВСН 12-13 and Wuxal Calcium, Boron at the microstage ВВСН 51-59 – 92.0% and 92.1% in Skinado and Somerwood garden pea varieties. In the same variant, maximum values of the use of photosynthetic active radiation (PAR) were observed in Skinado variety – 1.38 and Somerwood variety – 1.89%. This was 0.47 and 0.57% higher compared to the control. The longest period of symbiosis, both general and active, was 35.3 and 37.1, 25.4 and 26.7 days. This was 2.2, 4.6, and 1.6 days more compared to the control where liming was applied. The highest rates of symbiotic and active potentials were observed in Skinado and Somerwood varieties and amounted to 14.0 and 15.4, 7.8 and 8.6 thousand kg per day/ha, and the amount of symbiotically fixed nitrogen (SNF) was 148.2 kg/ha in Skinado and 172 kg/ha in Somerwood variety. Pea yield was 9.36 t/ha in Skinado and 11.09 t/ha in Somerwood varieties. This was 2.15 and 2.14 t/ha more compared to the control. Green pea output was 46.4% in Skinado and 50.3% in Somerwood varieties. This was higher compared to the control by 4.4 and 3.0%, respectively.</p> Oleksandr Mazur Ihor Didur Ihor Kupchuk Oksana Voloshyna Olena Mazur Copyright (c) 2022 Oleksandr Mazur, Ihor Didur, Ihor Kupchuk, Oksana Voloshyna, Olena Mazur 2022-10-03 2022-10-03 25 3 Effect of poppy (Papaver somniferum L.) fertilization with potassium and magnesium on the seed yield and its quality <p>In a vegetation pot experiment we explored the effect of fertilizers with potassium (KCl; 0.9 g K<sub>2</sub>O/6 kg of soil) and magnesium (ESTA Kieserite; 0.3 g MgO/6 kg of soil) applied together or separately to poppy on soil with good K and Mg supply on the seed yield, oil content and cadmium in the seed. Seed yields increased significantly after the application of KCl and ESTA Kieserite, respectively by 23.89% and 21.68%, as compared to the unfertilized control. Combined application of both fertilizers stimulated the yields significantly, i.e. by 15.26%. The seed oil content showed no significant changes among the treatments and ranged only between 42.1 and 43.6%. The pot production of oil in the fertilized treatments increased to 2.21-2.44 g/pot compared to 1.92 g/pot in the unfertilized control. The Cd content in seeds was very low, there were no differences among the treatments and it ranged only between 0.204 and 0.214 mg/kg fresh matter - FM (threshold level of 1.20 mg/kg wet weight). Therefore, the application of both KCl and ESTA Kieserite fertilizers can be recommended on soils well supplied with both nutrients.</p> prof. Ing. T. Lošák, PhD.
