Past triumphs, present struggles, and future conservation challenges of the autochthonous sheep breeds
No full textIn past decades, due to industry and market preferences, local sheep breeds have been
exposed to genetic erosion and extinction risk. According to the FAOs database, 26 sheep
breeds are documented in Serbia. More than half of these are autochthonous breeds/types
(Sjenica, Svrljig, Pirot, Pirot Improved, Lipe, Vlashko-Vitoroga, Bardoka, Baura, Tsigai,
Chokan Tsigai, Sharmountain, Karakachan, Krivovir, Vlasic), which have an aptitude for
wool, meat, and milk production, as well as considerable historical and cultural heritage
value. The analysis of the FAO statistical database and the National sheep yearbooks over a
20-year period reveals fluctuations in the population size of each native sheep breed/type. The
risk level varies; some types are at high risk of extinction, while others are not at risk. Longterm supportive measures are deemed essential not only for economic reasons but primarily to
ensure the survival of these breeds, reflecting their cultural, historical, and heritage value.Book of abstrac
Effects of different preparations containing selenium on selenium status and reproductive performance of common carp (Cyprinus carpio L.) broodstock
No full textThis study evaluated the efficiency of different Selenium supplements on blood Se
status and reproductive performance of carp broodstock. Female carp (n=120) were
distributed in 4 groups supplemented with Se as follows: control (non-supplemented),
sodium selenite 200 µg/kg feed, sodium selenite i/m injection (160 µgSe/kg body
weight), and selenized yeast 200 µg/kg feed. Blood was sampled on days 1, 20, and 30.
On day 30, samples of roe were taken from females, and samples of blood and milt
from 10 unsupplemented males. Larvae samples were taken after hatching. Plasmatic
Se concentration was 51.38±3.77 µg/kg (day 1) and did not vary significantly. The
erythrocyte Se concentration increased from 14.04±3.05 µg/kg (day 1), reaching
90.58±12.43 (day 20), to 212.38±57.87 µg/kg (day 30). Plasmatic glutathione peroxidase
activity in supplemented groups increased from 4.41±1.15 to 7.73±2.26 μkat/l and
plateaued until day 30. A similar pattern was observed for erythrocyte glutathione
peroxidase activity, ranging from 54.51±15.45 μkat/l (day 1) to 80.72± 6.82 μkat/l
(day 30). Se concentration and selenoenzyme activities in males did not differ from
the female control group. Roe Se content ranged from 48.26±17.53 μg/l in control
to 65.68±34.39 μg/l in fish supplemented selenized yeast, and in the pooled larvae
samples, ranged from 26-43 μg/l. The Se concentration in the milt was 24.78±4.27
μg/l. Results suggest that 250 µgSe/kg feed was sufficient to meet the requirements of
mature carp, sodium selenite being more efficient in elevating blood Se concentrations
and selenoenzymes activities, while selenized yeast being more efficient in roe and
larvae
Fibrinous pericarditis in slaughtered pigs: impact on welfare, growth performance and carcass and meat quality
No full textThis study aimed to determine the effects of fibrinous
pericarditis on blood welfare indicators, performance indices and carcass and meat
quality of slaughtered pigs. From a total of 144 examined pig hearts, the presence
of fibrinous pericarditis was recorded in 25.69% cases. The presence of fibrinous
pericarditis in slaughtered pigs was significantly associated with decreased
(P<0.0001) blood lactate and glucose levels. The presence of fibrinous pericarditis
in slaughtered pigs was significantly associated with reduced average lifetime daily
weight gain (P=0.0042), live weight (P=0.0045), hot carcass weight (P=0.0045),
cold carcass weight (P=0.0045) and lean meat content (P<0.0001). Consequently,
pigs showing fibrinous pericarditis produced the lower (P<0.0001) percentage of
„E“ class carcasses, but the higher (P=0.0079) percentage of „R“ class carcasses.
Pigs without fibrinous pericarditis produced the better meat quality, with the higher
(P=0.0465) percentage of red, firm and nonexudative meat. In contrast, the
presence of fibrinous pericarditis in slaughtered pigs was significantly associated
with abnormally elevated final meat pH (P<0.0001), high water-holding capacity
(lower drip loss; P<0.0001) and unfavourable dark colour (higher lightness and
yellowness; P<0.0001). As a result, pigs showing fibrinous pericarditis produced
the highest percentage of dark, firm and dry meat (P=0.0002). In conclusion,
assessing fibrinous pericarditis at the slaughterline has the potential to serve not
only as an indirect indicator of pig health and welfare on the farm of origin but also
of growth performance, carcass and pork quality
The influence of environmental factors on the constitution of donkeys
No full textThe donkey, as one of the oldest domestic animals, is spread over all continents. There
were no organized selection measures for centuries. The basic condition was that the
donkey could walk for a long time and carry a load. Such requirements, as well as the
ecological conditions in which they developed and live, caused donkeys, regardless of
where they live, to have practically the same body constitution, which is reflected in
the bony index. Regardless of the height of the withers, that is, the size of the body, the
relative relationships of individual parts of the body are quite similar. The donkey has
a strong body constitution.Related to a Serbian-language version of the following article:[https://vet-erinar.vet.bg.ac.rs/handle/123456789/4692
Značaj ocene i stalne kontrole biosigurnosti na farmama goveda i svinja
No full textBiosigurnost, dobrobit, dobra proizvođačka praksa i analiza rizika veoma su značajni
elementi za intenzivnu proizvodnju na farmama visoko mlečnih krava i svinja. Planska
primena biosigurnosnih mera presudna je u zaštiti zdravlja goveda i svinja i uspehu
same proizvodnje. Preporuka je da se stalno izgrađuje svest zaposlenih o unapređenju
biosigurnosti, da postoji aktivan odnos prema postojećim rizicima i da preduzete mere
predstavljaju ključ uspeha u osmišljavanju i pripremi planova biosigurnosti za svaku
konkretnu situaciju, odnosno farmu. Opšte je poznato da previdi, propusti i greške u
održavanju potrebnog nivoa biosigurnosti obično dovode do nastanka oboljenja, pada
obima proizvodnje, uginuća i gubitka zarade. Zato se na zdravstvenu zaštitu goveda i
svinja primenom značajno više preventivnih mera može ispuniti koncept u kome će se
realizovati rentabilna proizvodnja na farmama. Potrebno je da se istakne da je primena
biosigurnosnih mera na farmama goveda i svinja danas najvažnija mera za sprečavanje
potencijalnog unošenja i širenja patogenih uzročnika. Stoga mere biosigurnosti moraju
biti dobro definisane, praktične, funkcionalne i razumljive farmerima odnosno
odgajivačima goveda i svinja. U ovom radu prikazana je ocena stalne kontrole
biosigurnosti na farmama goveda i svinja, kao deo realizovanih projektnih zadataka.Related to an English-language version of the following article:[https://vet-erinar.vet.bg.ac.rs/handle/123456789/4701
Culicoides as vectors of orbiviruses, causative agents of particularly dangerous infectious diseases of importance for veterinary medicine
No full textIn the past, the worldwide distribution of bluetongue virus was limited to areas between
approximately 35 degrees south and 40 degrees north latitude, but recently it has
dramatically expanded in Europe to 58 degrees north latitude. The virus is thought to
have been introduced into central and western Europe by the transport of infected
animals or by wind-borne transmission of infected Culicoides, as well as by unknown
routes of spread. Nowadays, European countries are experiencing regular outbreaks of
bluetongue caused by different serotypes. Climate change is expected to affect the
distribution and range of many vector species due to global warming and altered
precipitation patterns. Climate change modifies long-term weather and climate patterns
that affect the behavior of arthropod vectors. Increased average winter air temperatures
allow arthropods to survive and extend their active period. An example of this is the
emergence of bluetongue virus serotype 3 in the summer of 2023 in the Netherlands,
the spread of the virus and its re-emergence in 2024. In the last 25 years, there has also
been an increase in the number of horse sickness serotypes circulating at the northern
border of the virus in sub-Saharan Africa. The current situation of equine sickness
resembles the distribution of bluetongue virus before the sudden expansion into
northern Europe in 2006. The wind-borne transmission of infected Culicoides is
particularly important from a control perspective, as it makes the restriction of
movement of susceptible animals significantly less effective in preventing the spread
of the disease. Currently, the most important role of Culicoides from a public health
perspective is their ability as biological vectors to transmit Oropouche virus, the
causative agent of Oropouche fever in humans.Related to an Serbian-language version of the following article:[https://vet-erinar.vet.bg.ac.rs/handle/123456789/4702
