AB  - Entomophagy is not a new phenomenon in the world. Moreover, it is a traditional diet in a
large part of the planet. However, in the European framework it belongs to the category of
novel food and although the topic is often debated, it represents a growing choice in human
and animal nutrition. Edible insects have the potential to serve as a healthy, sustainable alternative to animal protein sources due to their valuable nutritional composition. They may have
superior health benefits based on high levels of essential amino acids, omega-3 and omega-6
fatty acids, vitamin B12, iron, zinc, fibre and antioxidants. They could offer a myriad of environmental benefits, including overall reductions in greenhouse gas emissions and reduced
use of agricultural land and water. Future research should aim to understand the beneficial
effects of whole insects or insect isolates compared to traditional foods of animal and plant
origin. Although insects have the potential to be used as meat substitutes or dietary supplements, leading to benefits for human health and the environment, this paper does not aim to
ultimately propagate their use, but to point out their advantages and qualities, as well as potential dangers and risks, and finally to present ways of placing insects on the European market.

AB  - Različita fosfatna jedinjenja koja se koriste u industriji mesa nisu neophodna, ali se zbog
zadržavanja i vezivanja vode široko koriste. Upotreba fosfatnih aditiva dovodi do uspostavljanja
jonskog kapaciteta u mesnom proizvodu. A jedna od najvećih prednosti korišćenja fosfata je
smanjenje korišćenja natrijum nitrita, postizanje konzistencije i senzornih svojstva koja su
prilagođena potrošaču. Cilj ovog rada bio je ispitivanje količine prisutnih polifosfata i uticaja na
količinu odnosa vode i proteina. Obrađeni su podaci dobijenih analizom 30 uzoraka ispitanih
dimljenih svinjskih pečenica nakon industrijske proizvodnje. Na ispitanim uzorcima su
sprovedene sledeće analize: sadržaj fosfata (izražen kao P2O5), vlage, proteina, masti i pepela. Cilj
je bio da se uspostavi idealna količina odnosa fosfatnih soli i vode u toku procesa salamurenja.
Ovi podaci su iskorišćeni za obradu odnosa vode i proteina kao i procenu, odnosno proračuna
uticaja na nutritivnu vrednost. Najveći benefit korišćenja fosfata je smanjene korišćenja natrijum
nitrita, koji prisutan u znatnim količinama može imati štetan uticaj na ljusko zdravlje. Ovo je
upravo postignuto adekvatnim odnosom soli i vode. Cilj ispitivanja bio je praćenje prisustva
fosfata i usklađivanje vrednosti sa zakonskom regulativom, kao i dobijanje proizvoda sa
produženim rokom trajanja, ali i boje i ukusa. Sa porastom količine dodatih fosfata rastao je i
sadržaj vode (odnosa vode i proteina) u gotovim proizvodima dobijenih dimljenih pečenica.
Dobijene vrednosti količine fosfata u krajnjem proizvodu su bile ispod maksimalno dozvoljene
vrednosti fosfata propisane nacionalnom regulativom. Nutritivna vrednost dobijene dimljene
svinjske pečenice je 378 kJ, odnosno 90 kcal, sa vrednošći odnosa vode i proteina od 4.3.

AB  - Meso divlje svinje se smatra namirnicom visoke nutritivne vrednosti,
koju karakteriše nizak sadržaj masti i holesterola. Nizak nivo ukupne
masti ne podrazumeva i poželjan masno kiselinski sastav, kao ni odnos
zasićenih i nezasićenih masnih kiselina. Cilj ovog istraživanja je da
utvrdi masnokiselinski profil i hemijski sastav mesa divlje svinje. Tokom
lovne sezone u 2021 godini, uzeti su uzorci m. longissimus dorsi od
20 jedinki. AOAC (2021) je korišćen za utvrđivanje sadržaja vlage,
masti, proteina i pepela. Determinacija masnih kiselina izvršena je na
gasnom hromatografu (GC6890N, Agilent Tech., USA). Ukupan sadržaj
intramuskularne masti u ispitivanim uzorcima je bio nizak (1,9%), dok je
sadržaj sirovih proteina bio na nivou od 22,5%. Smatra se da je idealan
sadržaj ukupne masti svežeg mesa između 2 i 3%. U ispitivanim uzorcima
mesa divlje svinje, sadržaj masti je bio niži. Ipak, usled zahteva potrošača

i zdravstvenog uticaja masti su bazirani na sadržaju pojedinačnih masnih
kiselina. Poželjno je da odnos polinezasićenih i zasićenih masnih kiselina
bude veći od 0,4. Utvrđeni odonos u mesu divlje svinje bio je 0,56.
Nemaju sve masne kiseline isti uticaj na zdravlje ljudi. Smatra se da,
među zasićenim masnim kiselinama, najveći potencijalni štetni efekat
na kardiovaskularni sistem ima miristinska kiselina, usled toga što povećava nivo holesterola u krvnoj plazmi. Utvrđene koncentracije ove
kiseline u ispitivanim uzorcima mesa divlje svinje su bile niske (0.97%).
Najzastupljenija zasićena masna kiselina bila je stearinska (17.5%),
koja se smatra neutralnom, dok je njazastupljenija od svih utvrđenih
masnih kiselina bila oleinska kisleina (41.8%). Može se zaključiti da
meso divlje svinje ima povoljne nutritivne karakteristike, po pitanju

AB  - Wild boar meat is considered a meat of high nutritional value, regarding
its high iron and low fat content. However, low intramuscular fat level
does not imply favorable ratio of saturated to unsaturated fatty acids.
The aim of the present study is to determine fatty acid profile, along
with chemical composition of wild boar meat. A total of 20 samples of m.
longissimus dorsi were collected during the hunting season in 2021 year.
The AOAC (2001) method was applied for determination of moisture, fat,
ash and protein content. Analysis of fatty acid methyl esters (FAMEs) was
performed on a gas chromatograph (GC6890N, Agilent Tech., USA). Total
intramuscular fat content in the examined samples was low (1.9%), while
crude protein content was at the level of 22.5%. It is considered that ideal
intramuscular fat content of fresh meat is between 2 and 3%. In the current
study, wild boar meat had a lower fat content. However, due to consumers’
preference for lean meat, it could be estimate as favorable, regarding its
health impact. Health and nutritional indicators of fat are determined by
the level of particular fatty acids. The ratio of polyunsaturated to saturated
fatty acids should be higher than 0.4. Wild boar meat had the PUFA/SFA
ratio 0.56. Among the saturated fatty acids, not all have the same effect
on human health. Myristic acid has the most adverse effect by increasing
the concentration of cholesterol in plasma. Wild boar meat contained small
amounts of myristic acid (0.97%). The most abundant among saturated
fatty acid was stearic acid (17.5%) that is considered neutral. Among all, the
most abundant was unsaturated - oleic acid (41.8%). It can be concluded
that wild boar meat fulfill human health indicators based on its fatty acid
profile, as well as consumers’ expectations for lean meat.

AB  - Бовина спонгиформна енцефалопатија (БСЕ) или болест “лудих крава” је прогресивно,
фатално, неуродегенеративно обољење говеда. Спада у групу трансмисивих
спонгиформних енцефалопатија (ТСЕ), познатих и као прионске болести. Узрочник
обољења је абнормални, патолошки прион протеин који се акумулира у можданом
ткиву, доводећи до карактеристичних хистопатолошких промена. Болест је откривена
осамдесетих година прошлог века, и као потпуно нова и непозната болест крава са
израженим неуролошким знацима, представљала је не само изазов, него и обавезу
научне и стручне јавности да утврди етиолошки агенс и покуша зауставити даље
ширење болести. Епизоотиолошким истраживањима утврђено је да се болест преноси
путем контаминиране хране, пре свега месно-коштаног брашна (МКБ) преживара које
садржи инфективни прион протеин. Европска Комисија прописује неколико регулатива
којима се забрањује употреба ових хранива у исхрани преживара, и тиме спречава
“рециклирање” БСЕ агенса у популацији преживара. Као једна од мера контроле и
превенције обољења врши се преглед хране за животиње, а класична (оптичка)
микроскопија је уз методу полимеразне ланчане реакције (PCR), званични метод у
Европској Унији и код нас за утврђивање прерађених протеина животињског порекла у
храни за животиње. Принцип методе своди се на детектовање састојака животињског
порекла у узорку хране који је припремљен на одговарајући начин а сама
идентификација делова анималног порекла обавља се у две фракције узорка. На основу
типичних, микроскопски уочљивих карактеристика посматрају се фрагменти костију,
мишићна влакна, длаке, перје, рожина, шкрге и други делови животињских ткива и тела.
Микроскопијом се лако уочава разлика између МКБ добијеног од копнених животиња
и рибљег брашна, а главни недостатак методе огледа се у немогућности утврђивања
врсте копнене животиње од које потичу састојци хране. Овом методом могу се
детектовати анимални протеини у врло малим количинама (< 0,1%), чинећи је веома
осетљивом, а предност методе огледа се свакако и због саме брзине извођења, и не
захтева скупу опрему и реагенсе. У нашој земљи, овај метод се успешно спроводи у две
акредитоване лабораторије (Научни институт за ветеринарство „Србије“ и Научни
институт за ветеринарство „Нови Сад“), а успешност се огледа и у сарадњи са
референтним ЕУ лабораторијама и упоредним међулабораторијским испитивањима.
AB  - Bovine spongiform encephalopathy (BSE) or "mad cow disease” is a progressive, fatal,
neurodegenerative disease of cattle. It belongs to the transmissible spongiform
encephalopathies (TSE), also known as prion diseases. The causative agent is an
abnormal, pathological prion protein that accumulates in brain tissue, leading to
characteristic histopathological changes. The disease was discovered in the 1980s, and as
a completely new and unknown disease of cows with pronounced neurological signs, was
not only a challenge, but also an obligation of the scientific and professional public to
determine the etiological agent and try to stop the further spread of the disease.
Epizootiological studies have established that the disease is transmitted through
contaminated feed, primarily meat and bone meal (MBM) of ruminants containing
infectious prion protein. The European Commission has issued several regulations
prohibiting the use of these nutrients in the ruminant diet, thereby preventing the
"recycling" of BSE agents in the ruminant population. The officially accepted methods by
the European Union for detection of presence of animal proteins in feed are classical light
microscopy and PCR, as one of the control measures in prevention and control of disease.
The principle of the method is to detect the components of animal origin in a feed sample
that has been properly prepared. The identification of the components of animal origin is
carried out in two fractions of the sample. Bone, muscle fibers, hair, feathers, horns, gills
and other parts of animal tissues can be observed on the basis of typical, microscopically
characteristics. Microscopy can easily discern the difference between MBM obtained
from terrestrial animals and fishmeal, and the main disadvantage of the method is the
inability to determine the species of terrestrial animal from which the food components
originate. Animal proteins could be detected in very small amounts (<0.1%) by this
method making it very sensitive, and the advantage of the method is certainly due to its
speed of execution, and does not require expensive equipment and reagents. In our
country, this method is successfully implemented in two accredited laboratories
(“Scientific Veterinary Institute of Serbia” and Scientific Veterinary Institute “Novi
Sad”), and the success is reflected in cooperation with EU reference laboratories and
comparative inter-laboratory testing.

abstract = "Бовина спонгиформна енцефалопатија (БСЕ) или болест “лудих крава” је прогресивно,
фатално, неуродегенеративно обољење говеда. Спада у групу трансмисивих
спонгиформних енцефалопатија (ТСЕ), познатих и као прионске болести. Узрочник
обољења је абнормални, патолошки прион протеин који се акумулира у можданом
ткиву, доводећи до карактеристичних хистопатолошких промена. Болест је откривена
осамдесетих година прошлог века, и као потпуно нова и непозната болест крава са
израженим неуролошким знацима, представљала је не само изазов, него и обавезу
научне и стручне јавности да утврди етиолошки агенс и покуша зауставити даље
ширење болести. Епизоотиолошким истраживањима утврђено је да се болест преноси
путем контаминиране хране, пре свега месно-коштаног брашна (МКБ) преживара које
садржи инфективни прион протеин. Европска Комисија прописује неколико регулатива
којима се забрањује употреба ових хранива у исхрани преживара, и тиме спречава
“рециклирање” БСЕ агенса у популацији преживара. Као једна од мера контроле и
превенције обољења врши се преглед хране за животиње, а класична (оптичка)
микроскопија је уз методу полимеразне ланчане реакције (PCR), званични метод у
Европској Унији и код нас за утврђивање прерађених протеина животињског порекла у
храни за животиње. Принцип методе своди се на детектовање састојака животињског
порекла у узорку хране који је припремљен на одговарајући начин а сама
идентификација делова анималног порекла обавља се у две фракције узорка. На основу
типичних, микроскопски уочљивих карактеристика посматрају се фрагменти костију,
мишићна влакна, длаке, перје, рожина, шкрге и други делови животињских ткива и тела.
Микроскопијом се лако уочава разлика између МКБ добијеног од копнених животиња
и рибљег брашна, а главни недостатак методе огледа се у немогућности утврђивања
врсте копнене животиње од које потичу састојци хране. Овом методом могу се
детектовати анимални протеини у врло малим количинама (< 0,1%), чинећи је веома
осетљивом, а предност методе огледа се свакако и због саме брзине извођења, и не
захтева скупу опрему и реагенсе. У нашој земљи, овај метод се успешно спроводи у две
акредитоване лабораторије (Научни институт за ветеринарство „Србије“ и Научни
институт за ветеринарство „Нови Сад“), а успешност се огледа и у сарадњи са
референтним ЕУ лабораторијама и упоредним међулабораторијским испитивањима., Bovine spongiform encephalopathy (BSE) or "mad cow disease” is a progressive, fatal,
neurodegenerative disease of cattle. It belongs to the transmissible spongiform
encephalopathies (TSE), also known as prion diseases. The causative agent is an
abnormal, pathological prion protein that accumulates in brain tissue, leading to
characteristic histopathological changes. The disease was discovered in the 1980s, and as
a completely new and unknown disease of cows with pronounced neurological signs, was
not only a challenge, but also an obligation of the scientific and professional public to
determine the etiological agent and try to stop the further spread of the disease.
Epizootiological studies have established that the disease is transmitted through
contaminated feed, primarily meat and bone meal (MBM) of ruminants containing
infectious prion protein. The European Commission has issued several regulations
prohibiting the use of these nutrients in the ruminant diet, thereby preventing the
"recycling" of BSE agents in the ruminant population. The officially accepted methods by
the European Union for detection of presence of animal proteins in feed are classical light
microscopy and PCR, as one of the control measures in prevention and control of disease.
The principle of the method is to detect the components of animal origin in a feed sample

AB  - Introduction: Modern antiparasitic pharmacotherapy faces several important challenges. An 
increasing number of reports refer to the resistance of parasitic nematodes to conventional 
antiparasitic drugs, while dose increasing manifests their toxicity. Particularly important for 
veterinary medicine is the fact that most antiparasitic drugs require a long withdrawal period 
after application in animals whose tissues are intended for human consumption. 
Aims: To examine the potential antinematodic effect of selected monoterpenoid and 
diterpenoid active principles of essential vegetable oils and determine the mechanism by 
which they achieve antiparasitic effects.
Materials and Methods: Investigation of the interaction of active principles of essential 
vegetable oils with cholinergic and GABA-ergic nematode receptors on neuromuscular 
preparation Ascaris suum and Caenorhabidis elegans culture.
Results: The terpenoids alpha-pinene, p-cymene, carveol, carnosol and cinnamaldehyde do 
not show any pharmacological effects on the contractions of the neuromuscular preparation A. 
suum. The monoterpenoid carvacrol exhibits the properties of the competitive / noncompetitive nicotinic acetylcholine receptor (nAChR) antagonist A. suum and effectively and 
significantly inhibits neuromuscular contractions caused by increasing acetylcholine 
concentrations. - carvacrol does not alter the EC50 value of acetylcholine The tested active 
principles of essential oils in our tests showed a specific and unique mechanism of action that 
potentially enables them high efficacy, even in nematodes resistant to classical anthelmintics.
Conclusion: Based on our results, carvacrol, carveol, menthol and thymol are very serious 
candidates for independent use in antinematode therapy or use in combination with drugs 
agonists of GABA receptor nematodes.
