The aim of this study was to compare the effect of two alternative rearing systems (floor and organic) on egg quality traits of New Hampshire laying hens in three different phases of the productive cycle (32, 48 and 72 weeks of age). Egg samples (15 eggs per group) were analysed for quality (egg weight, egg shape index, albumen height, Haugh unit, yolk colour) and chemical composition (dry matter, minerals, proteins and lipids). Egg weight, dry matter and protein content increased, while albumen height, Haugh unit and lipid content decreased with hen age (p≤0.05). Eggs from the floor rearing system had a higher shape index and lipid content compared to organic eggs (p≤0.05). Both factors and their interactions had a significant effect on yolk colour (p≤0.05).

Insect’s bionomics and development are highly dependent on the environmental temperature. For centuries, this fact has been used for the control of storage pests. However, the temperature threshold depends on the species, life stage, acclimation and exposure period. This work assessed the effects of low temperatures (4, -4, -10, -15 and -18°C) and exposure period (10, 30, 60, 120 and 180 min) on the survival and development of Plodia interpunctella larvae, and adults of Sitophilus oryzae and S. zeamais, the prevalent maize pests in Serbia. Data were analysed using one-way and two-way ANOVA. Additionally, Probyt analysis was performed to determine the LT50 and LT99. The first significant effects were recorded at -4°C for S. oryzae when the mortality was 41% after 120 and 52% after 180 min of exposure. At -10°C, the mortality of S. zeamais was significant after 180 min (52.5%) and increased with the exposure period. The significant mortality of P. interpunctella larvae was at -15°C after 10 min (55.5%). At -18°C, P. interpunctella larvae were the most susceptible and 98% of mortality was recorded after 10 min, while 77.5% of S. oryzae and 68% of S. zeamais was recorded after 10 min. Twoway ANOVA showed that both factors (temperature and exposure) significantly affected the mortality of tested species, but the first factor was the most influential. These results indicate that temperature and exposure period should be adjusted to specific pest, while in combined infestations the temperature should be adjusted to the most tolerant one.

The research was conducted in the experimental-production plum orchard during 2013. Some of the most important physical and mechanical properties of the fruit were investigated in three plum cultivars („Čačanska Rana‟, „Čačanska Lepotica‟ i „Čačanska Najbolja‟) grafted on four rootstocks: one generative Myrobalan (Prunus cerasifera Ehrh.) and three vegetative ones (Pixy, St. Julien A and Ferley). St. Julien A induced the highest all three fruit dimensions in „Čačanska Najbolja‟, and length and thickness in „Čačanska Lepotica‟. Myrobalan and Fereley had the same effect in the „Čačanska Rana‟. St. Julien A influenced the biggest fruit firmness in „Čačanska Najbolja‟ and the smallest in „Čačanska Lepotica‟.

The aim of the paper was to determine the level of soil contamination with lead and perform risk assessment by calculating the Hazard Quotient Index (HQI). The research was carried out during 2015 and 2016 at three locations in Herzegovina (Mostar, Capljina, and Stolac), where nectarine cultivars ('Big Top' and 'Caldesi 2000') were cultivated. At the Mostar and Capljina locations, the total content of lead in the soil exceeded MPC values in both years of research. Estimated daily intake (EDI) and estimated weekly intake (EWI) values of lead in the studied nectarine varieties showed no acute or chronic risk for human health.

The two-year research investigated the impact of different varieties and fertilizers on the root yield and the vitamin C content in the root of parsley. Three varieties of parsley were used and three fertilization treatments were applied (mineral, organic and organomineral fertilizer) as well as control. The varieties used in the research were: 'Domestic Sawmills', 'Mooskrause', 'Berlin Semi-Long'. The root yield and the vitamin C content in the root of parsley were significantly influenced by variety and type of fertilizer. With use of organic fertilizer, the highest yield of roots was achieved in both research years. The lowest vitamin C content was found in the unfertilized control, while the highest vitamin C content was obtained in the organomineral fertilizer treatment, but did not differ significantly from the treatment with organic fertilizer.

Plodia interpunctella (Hubner), the Indian meal moth (IMM), is a major lepidopteran storage pest worldwide. IMM larvae can be found in high abundance in stored maize and cause huge losses in seed germination and seed viability. This work aimed to assess the susceptibility of six maize hybrids (NS 6140, NS 640, NS 1090, NS 444 - dent type, NS 620k - pop-corn type, Red-aleurone maize - maize with an altered aleuron color) to IMM attack and suitability for pest's development. Standard laboratory diet (SLD) was used as a positive control. Under laboratory conditions, the following IMM life history parameters were monitored: larval mortality, mean developmental duration (egg to adult), adult emergence, adult lifespan and female fecundity. Kernel susceptibility was determined based on the Susceptibility Index (SI). The highest mortality of IMM larvae was on NS 620k (35.25%) compared to the other maize hybrids (11.2-19.5%). The highest number of emerged adults was on Red-aleurone maize (17.5), and the lowest on NS 620k (4.0). The longest lifespan was recorded for moths reared on NS 6140 and NS 640 (8.5 and 8.7 days, respectively). The highest female fecundity was on SLD (115.8 eggs), on Red-aleurone maize (44.3 eggs), while females reared on NS 620k laid the lowest number of eggs (22.8 eggs). Moths reared on NS 620k had the shortest body sizes (0.9 cm), which indicated reduced moths fitness. SI showed that Redaleurone maize (SI=7.79) was the most susceptible to IMM attack, while NS 620k (SI=3.08) was the least susceptible.

A two-year investigation (2009-2010) of the presence and distribution of pepper (Capsicum annuum L.) viruses in Serbia revealed that viruses occur each year in open-field production. Disease incidence, as estimated by the number of symptomatic plants in the field, highly varied depending on the year and sampling locality. Disease incidence ranged from 20% to 60%. Four viruses: Cucumber mosaic virus (CMV), Potato virus Y (PVY), Alfalfa mosaic virus (AMV) and Pepper mild mottle virus (PMMoV), of which PVY was predominant, were detected by serological testing of pepper samples collected from many localities in Serbia. Molecular detection of PVY was performed based on amplification of a 975 bp fragment in all tested samples, using the specific primers PVYc/PVYd that amplify the gene for P1 protein. The RT-PCR products derived from the four isolates (PL-28-09, PL-15-09, PL-3-10, PL-108-10) of PVY were sequenced (KC288142, KC288143, KC288144, and KC288144, respectively) and compared with the PVY sequences available in GenBank. Sequence analysis, conducted with MEGA5 software, revealed 99.8-100% nt identity among the four Serbian PVY isolates from pepper. The sequences of PVY isolates from Serbia share the highest nucleotide and amino acid identity with isolates from Slovenia, Croatia, Germany, and tobbaco isolate from Serbia. All of the four Serbian isolates were clustered in sub-group N-1 with other European isolates of necrotic strains.

As a fruit crop, the pear is preferably grown and esteemed for its high utility value. Over recent decades, there have been great fluctuations in both quantity and quality of the pear fruit for a variety of reasons (obsolete growing technology, cultivar diversity, increased fire blight attacks, market instability, etc.). Given the favourable environmental conditions in Serbia and pear fruit shortage on domestic and foreign markets, producers' interest in pear production has increased in the last several years. The economic performance of a pear orchard is largely dependent on market conditions and pear marketing possibilities. Establishing a pear orchard requires a comprehensive analysis of agroeconomic conditions which govern both the choice of cultivars and orchard size. Therefore, the objective of this study was to analyse pear orchard establishment costs. Two cultivars were used i.e. 'Williams' and 'Santa Maria'. The results of the agroeconomic analysis show that the investment costs of establishing a 1 ha orchard amount to €8,975.75. Orchard management costs are €2,020.25 in the first year, €1,803.25 in the second year and €3,026.00 in the third year. Total investment costs associated with orchard establishment and management during the first three years are € 18,510.25. Management costs for a fully productive orchard are €4,657.00. The return on investment, along with profit, is achieved in the fifth year. If the intensive orchard produced a yield higher by 35% than the average yield projections, as typical of high-density production systems, the return on investment would be achieved in the fourth year.

Domestic donkey is a transboundary breed present in many Balkan countries. According to the Law on Animal Production, in many Balkan countries, for every breed of domestic animals it is necessary to create a separate breeding programme. Based on the results of a study evaluating the main morphological, reproductive and functional traits in 47 domestic donkeys in Macedonia during 2017 and 2018, current standards and breeding goals were defined for the next national breeding programme of this breed. According to the fact that the domestic donkey is a metapopulation and transboundary breed in almost all Balkan countries, it is a good recommendation to create a regional breeding programme with flexible standards and breeding goals for this relative of horses for all Balkan countries together.

Niacin is a reactive part of NAD and NADP, which are co-enzymes in numerous oxidative and reductive reactions. In early lactation, there is an increased lipid mobilization, accompanied by inflammatory response and oxidative stress. The aim of this study was to examine the effect of niacin administration in cows during early lactation in reducing lipid peroxidation i.e. MDA (malondialdehyde) concentration. Niacin was administered through feed two weeks before and two weeks after calving. Blood samples were taken in the week preceding calving and in the first and second week after calving. MDA concentration was significantly lower in cows receiving niacin compared to the control group during all three samplings: 1.89±0.33:1.42±0.13 (calving, week 0); 2.37±0.41:1.64±0.15 (first week) and 2.6±0.45:1.8±0.17μmol/L (second week). In control cows, no significant correlation between MDA and NEFA concentrations was found compared to cows fed niacin. In cows receiving niacin, the concentration of MDA linearly increased, as did the NEFA concentration. Niacin supplementation in early lactation can decreaselipid peroxidation in cows. Reduced lipid peroxidation in cows can be a consequence of the antilipolytic effect of niacin.
