The productivity and quality of grapes and wine are significantly influenced by changing climate conditions in vineyard regions worldwide. This study assesses changes in temperature, precipitation, and viticultural indices between the periods of 1971–1990 and 2000–2019 in Trebinje, a vineyard area located in the Herzegovina region of Bosnia and Herzegovina. Between the two periods, mean annual temperature increased by 2 °C and mean vegetational temperature by 2.4 °C, while mean precipitation remained within the range of climatological variability, with annual values increasing by 6% and vegetational values decreasing by 4.6%. Warming resulted in a longer duration of the vegetation season by 23.7 days, a reduced risk of late spring frosts, and an increased risk of very high temperatures during summer. These changes led to the reclassification of Trebinje vineyards’ climate from Region III to Region V, based on the Winkler index values, from a “temperate warm” to a “warm” category, based on the Huglin heliothermic index, and from “cool nights” to “temperate nights” based on the cool nights index. The category of the dryness index remained unchanged between the two periods. The findings emphasize the necessity for a renewal of the viticultural zoning and the development of climate change-adaptation plans for this region.

The present study aimed to evaluate the antioxidant capacity of ethanolic extracts from post-harvest sunflower and maize stalk residues, and their impact on the chemical composition, physicochemical parameters, lipid oxidative stability, microbiological properties, and sensory characteristics of pork liver pâtés over a 90-day storage period. Four formulations were prepared: a control group (CON), a batch with butylated hydroxytoluene as a synthetic antioxidant (BHT), 1% ethanolic extract from sunflower residues (SSRE), and 1% ethanolic extract from maize residues (MSRE). The MSRE had a higher total phenol content and showed better antioxidant activity relative to the SSRE (p < 0.01). The addition of SSRE decreased the lightness and increased the redness in the pork liver pâtés, with these pâtés showing the highest total color difference compared to the control (p < 0.01). The crop extracts increased the n-6 and total PUFA contents in pâtés and improved the PUFA/SFA ratio (p < 0.01). Formulations containing crop residue extracts showed higher TBARs and POV values than the control and BHT group (p < 0.01), indicating a pro-oxidant effect and accelerated lipid oxidation in pâtés during storage. As far as microbiological quality, the presence of crop residue extracts decreased the total viable count, lactic acid bacteria, and psychotropic aerobic bacteria (p < 0.01). The incorporation of crop extracts in the pork pâtés impaired their sensory quality, particularly color, odor, aroma, and flavor, and decreased their overall acceptability. These results indicated that, while the crop residue extracts were not as effective as synthetic antioxidants in preserving the lipid stability of pâtés, they demonstrated potential for enhancing the microbial quality of this type of meat product.

Large quantities of agricultural residues are generated every year. Most of the crop-based residues are underutilized, mainly left to decay on the land or to be burnt, which can lead to an increase in a load of environmental pollution. Considering this, different strategies have been developed to use these renewable resources as raw materials for the production of bioactive compounds, their isolation and characterization, and potential application in a wide range of fields, particularly in the food industry as natural preservatives. In this study, the antibacterial efficacy of wheat, sunflower, and maize crop residue ethanolic extracts against six bacterial strains (Salmonella Typhimurium, Salmonella Enteritidis, Staphylococcus aureus, Escherichia coli, Listeria monocytogenes and Yersinia enterocolitica) was evaluated by the broth microdilution method. Used extracts inhibited the growth of selected microorganisms with a minimal inhibitory concentration (MIC) of 320 μg/mL for most of the tested bacteria. L. monocytogenes showed a MIC value of 640 μg/mL for wheat ethanolic extract, and the MIC value of sunflower ethanolic extract for S. Typhimurium was 160 μg/mL. There were no minimum bactericidal concentration (MBC) values for any of the bacteria within the extract’s concentration ranges tested (≤ 2560 μg/mL). The results of the present study indicate that crop residue ethanolic extracts could exhibit bacteriostatic effect and therefore have the potential as natural additives in food preservation.

The modern pig production chain is increasingly focused on biosecurity, quality, and safety of meat and is associated with many challenges impacting world meat markets, such as animal disease outbreaks and sanitary restrictions, trade regulations and quality requirements. To overcome such challenges and assure more consistent pork meat quality (and safety), there is a need to develop an effective and reliable monitoring system in a farm–abattoir continuum that can be based on selected biomarkers. This study assessed interrelations of selected stress and inflammation biomarkers (acute phase proteins (APP)) between farm biosecurity score versus pork meat quality traits after two different lairage periods. Briefly, the maximum recorded levels of stress hormones (436.2 and 241.2 ng/mL, for cortisol and Chromogranin A (CgA), respectively) and APP (389.4 and 400.9 μg/mL, Pig Major Acute Proteins (MAP) and Haptoglobin (Hp), respectively) at four commercial farms were within the recommended threshold values. Cortisol and APP were negatively correlated to the internal and total biosecurity scores of farms. The increase of level of both sets of biomarkers was found at bleeding (after transportation and lairage period), but with lower values after long (18–20 h) versus short (1–3 h) lairage lay-over time. In general, negative correlation was confirmed between stress and inflammation biomarkers and carcass/meat quality traits. The farm total biosecurity level significantly affected chilling yield, meat temperature, and a* value. Pig-MAP emerged as a good biomarker with a promising potential for assessment and anticipation of broad aspects in the pork meat chain. It can be used for detection of failures in the pig production system and might be incorporated in certification programs for the pork meat industry.

The effect of dietary lignocellulose on broilers performance, intestinal microbiota and morphology, pH of digesta and litter humidity after 28 and 42 days of the experiment was evaluated. A total of 384 Cobb500 chickens (initial weight: 41.88±1.56 g) were divided into 4 groups with 24 replications and fed with control diet (C), a control diet with added 0.4% of lignocellulose (T1), a diet with added 0.6% of lignocellulose at the expense of soybean meal and maize (T2), and a diet supplemented with 0.6% of lignocellulose at the expense of soybean meal (T3). T2 treatment significantly influenced body weight, weight gain (WG), feed intake (FI) and feed conversion ratio (FCR). T2 and T3 treatment increased average LAB and Bifidobacterium spp. count, and decreased the number of Escherichia coli in the ileum and cecum, while differences in cecal Clostridium perfringens count among 0.4% and 0.6% treatments were not observed. Feeding the lignocellulose diet did not affect the relative weights of empty proventriculus, gizzard or intestines, but led to a decrease in pHs. T3 treatment caused an increase of the villi heights and significantly lower moisture content in the litter. Even though the addition of lignocellulose into broilers diet positively influenced performances, changes in intestinal microbiota and villi heights, based on the results of the present study, supplementation with 0.6% lignocellulose is recommended.

This study evaluated the quality of 78 honeys of six different floral types (Acacia, sage [Salvia officinalis L.], linden, chestnut, honeydew and blossom), mainly from Bosnia and Herzegovina. Reducing sugars, sucrose content, moisture, hydroxymethylfurfural (HMF), free acidity, water-insoluble content, diastase activity, electrical conductivity were analysed. The samples of honey, collected during 2016-2017, were analysed using recommended methods. Results show that in 2016 and 2017, a great number of individual honeys sampled were of insufficient quality to satisfy regulatory requirements. Among the overall determined parameters, hydroxymethylfurfural and diastase activities in some honeys were not acceptable according to national and international regulations. A correlation between free acidity and electrical conductivity was found in both acacia and blossom honeys. HMF content and diastase activity was strongly negatively correlated in both acacia and blossom honeys. The quality of the honeys was varied, based on botanical origins, and presumably, handling and storage conditions.

Proliferative enteropathy, also known as proliferative ileitis, is considered to be one of the most economically important diseases in pig production worldwide. The estimated losses per affected growing pig usually range from US $1 to $5. The disease is caused by Lawsonia intracellularis, a Gram-negative, obligately intracellular bacterium. Control of the disease can be achieved with the use of vaccines or antibiotics. Recently there has been an increase in the efforts in the control of certain pathologies of the digestive system with phytogenic additives. The aim of this work was to assess the effects of a phytogenic additive on the histomorphometric characteristics of the intestines in weaned pigs with a subclinical infection with L. intracellularis acquired spontaneously. Histomorphometry analysis showed that crypt depth was significantly shorter (P<0.05), and the villus-height-to-crypt-depth ratio (P<0.05) significantly greater in the treatment group than the control. This improvement in the histological parameters of the intestine, considered to be indicators of its health, proved the positive effect of the tested additive on the digestive system in pigs.
