AB  - Poljoprivredna proizvodnja u Republici Srbiji predstavlja značajnu granu privrede.
Stočarstvo pre svega karakterišu usitnjena porodična gazdinstva, koja se tradicionalno
bave ovom delatnošću. Ovčarstvo predstavlja važnu granu stočarstva u Republici
Srbiji, gde se na preko 155 000 poljoprivrednih gazdinstava gaji ukupno preko 1,7 miliona
ovaca. Najveći deo populacije ovaca čine autohtone rase, u prvom redu različiti sojevi
pramenke, zatim, u značajno manjem broju i cigaja, koje se najčešće gaje u poluekstenzivnim
sistemima. Mnogi sojevi autohtonih rasa imaju ugrožen status i neophodno
je unaprediti mere očuvanja i zaštite ovih dragocenih autohtonih genetičkih resursa,
koji imaju značajan potencijal u održivoj poljoprivrednoj proizvodnji. Posebna pažnja
treba da se posveti odabiru priplodnih ovnova, zbog toga što je njihov uticaj na populaciju
najveći, s obzirom na činjenicu da jedan kvalitetan ovan u sezoni parenja, upari
preko 40 ovaca i ostavlja svoje brojne potomke. Iz tog razloga, prilikom izrade selekcijskih
programa za određenu rasu, posebnu pažnju treba posvetiti priplodnim ovnovima
i njihovim proizvodnim i reproduktivnim karakteristikama. Pored ostalih selekcijskih
kriterijuma, kliničkim pregledom genitalnih organa i morfometrijskom analizom testisa
pri odabiru priplodnih ovnova u značajnoj meri se može poboljšati, ne samo zdravlje
zapata, već i kvalitetne rasne odlike i brojnost populacije. Poznato je da je pored zdravstvenog
statusa genitalnih organa, kapacitet testisa za proizvodnju sperme u srazmeri
sa obimom testisa (veličina testisa). Ustanovljeno je da ovnovi sa većim obimom testisa
ostavljaju veći uticaj na populaciju i mogu da se pare sa većim brojem ovaca. Oni ostavljaju
veći broj potomaka, te svoje kvalitativne i kvantitativne rasne odlike mogu brže širiti
u populaciji u odnosu na priplodnjake koji imaju manje testise, koji stvaraju manje
sperme. Na osnovu literaturnih podataka, koji su proistekli iz opsežnih ispitivanja zaključeno
je da priplodni ovnovi starosti preko 1,5 godine, sa zdravim genitalnim organima moraju imati obim testisa najmanje 33 cm. Idealno bi bilo da svaki priplodnjak ima
obim testisa ≥ 35 cm zbog toga što tada može uspešno da pari i preko 40 ovaca tokom
sezone parenja. U zemljama sa razvijenim ovčarstvom, ova saznanja čine glavne selekcijske
smernice i kriterijume, te je shodno tome, cilj da kvalitetni priplodnjaci imaju
obim testisa ≥ 38 cm. Lipski soj pramenke predstavlja autohtonu rasu Republike Srbije,
koji je prema klasifikaciji Pravilnika o genetičkim resursima do 2019. godine spadao u I
kategoriju (kritično ugrožene rase), sa brojem priplodnih grla od oko 800 komada. Zahvaljujući
subvencijama, brojnost populacije se povećala i u 2021. godini je postignuto
2 000 registrovanih priplodnih jedinki, tako da ona nije više kritično ugrožena, već spada
u kategoriju “potencijalno ugroženih”. Ispitivanja populacija lipskog soja pramenke
su dokazala da je zdravlje genitalnih organa priplodnih ovnova dobro, prosečan obim
testisa je 38,35 cm, ali je opseg varijacija velik. Ova vrednost podrazumeva odličan prosek
na nivou cele populacije, ali zbog toga što je većina zapata mala (do 20 priplodnih
jedinki) i često samo sa jednim priplodnim ovnom u zapatu, ovnovi sa testisima nedovoljnog
obima mogu imati nepovoljan uticaj, ne samo na zapat u kome se gaji, već i na
celu populaciju lipske ovce. Sa aspekta očuvanja i unapređenja ovih dragocenih autohtonih
genetičkih resursa, poželjno je osavremeniti i selekcijski pristup koji uključuje kriterijume
vezane za genitalni trakt, sa ciljem da svaki zapat ima kvalitetnog ovna.
AB  - The agriculture represents an important branch of economy in the Republic of
Serbia. Animal production is mainly based on traditional small family housholds. Sheep
production is an important branch of agriculture in the Republic of Serbia, where a total
of 1.7 million sheep are reared in over 155.000 households, mainly under semiextensive
menagement. The majority of sheep are autochthonous breeds and local types adapted
to the local environment. Because of the endangered status of the autochthonous sheep
breeds, conservation and improvement of these precious populations is needed, as they
have a major potential in the sustainable agricultural production. The main focus should be given to the selection of breeding rams, as they have the biggest impact on the
population quality. One high quality breeding ram can mate over 40 ewes over the mating
seasone and leave offspring. Taking this in mind, when the selection criterias are
defined for a breed, a special attention should be given to the ram, to its productive and
reproductive traits. Amongother selection criteria, the clinical assessment of the genital
tract with a special attention on scrotal circumference could result in better health and
quality of the population. It is well known that rams with bigger scrotal circumference
(bigger testicles) can have a better reproductive capacity and can serve more ewes in
the mating season, what makes a stronger impact of rams on the population quality. In
countries with specialized sheep production these characteristics are inclusded into the
selection measures and breeding rams older than 1.5 years with healthy genitals should
have a scrotal circumference of minimum 33 cm, and the ideal score means that the
ram should have is≥ 35 cm, and the elite ones ≥ 38 cm. The Lipe sheep is a local autochthonous
breed of the Republic of Serbia, which has a breeding population size of 800
animals in 2019. According to the national legislation that time it had a status of a critically
endangered breedwith. As a result of hogher subsidies for the last few years, the
population size rises and in 2021 reached 2000 breeding animals which means it got a
status of potentially endangered breed. Assessment of the genital tract ofbreeding rams
of the Lipe sheep showed good health of the genitalia, with an average scrotal circumference
of 38.35cm, but with evidence of big variations. The average scrotal circumference
of 38.35cm means an excellent result on a population level. Eventhough the overall
scrotal circumference is excellent on the population level, because of the fact that most
of the herds are small (up to 20 breeding animals) with only one breeding ram, the animals
with insufficient values of scrotal circumference (≥ 33) could have negative results
not only at the herd level, but also at the population level of the endangered Lipe
sheep.With the aim to improve and save the endangered autochthonous rare breed and
ensure a high quality elite breeding rams in each flock, it is necessary to update the selective
measures with new criteria regarding the assessment of the male genital tract.

8719 livestock breeds, 26 percent are classified as at risk of extinction, 13 percent as not at risk, 6
percent as extinct and 55 percent as being of unknown risk status. Therefore, conservation is of
high priority. The Podolian cattle is one of the most endangered breed from the list of native breeds
of livestock in Serbia. In 2021 only 338 breeding animals were registered. The breed is known as
a precious resource of the local landscape enrichment, national heritage and history. According to
the population size of the Podolian cattle, a slight increasing tendency can be evidented. The
population size is variable (154 breeding animals in 2009, 252 in 2010, 270 in 2011, 260 in 2012,

endangered). Over the time the governmental subsidies influenced the overall slight increase of
the number of breeding animals, but the population size is not stabile. Improved conservation
program should be applied to save the autochthonous endangered breed suitable for heritage

Serbia. The specific climate and the unic habitat include a high variability of flora and fauna
of grasslands, pastures and meadows throughout the country, ensuring high biodiversity of the
ecosystem. Autochthonous breeds are most adapted to the local environment. The present
study was performed on 143 autochthonous sheep breed flocks in Serbia during the grazing
season from March to October 2016 and 2017, and included a total of 1069 adult sheep. Tick
infection was detected in all tested flocks, affecting 49.02% of examined sheep. The most

Rhipicephalus bursa (15.15%), Ripicephalus sanguineus (8.70%), Hyalomma savignyi
(3.18%), Haemaphysalis punctata (2.81%) and Dermacentor recticulatus (2.62%). In tested
years the recorded tick infections showed two peaks, in spring (April-May) and in autumn
(September-October). The considerable difference between detected spring and autumn tick
populations can be attributed mainly to climatic and environmental conditions of the
ecosystem where ticks and sheep cohabitat.

AB  - Introduction. Twin-calving occurs in 3 to 5 % of Holstein Friesian cattle, and it is mostly followed by reproductive and economic problems. This evaluation will compare the service period and the milk yield in cows with single and twin births at a Hungarian large-scale farm. Materials and Methods. The data were collected from 4223 cows between 2000 and 2010. In Cox's regression model (service period) and general linear model (milk production traits), the type of calving (single/twin), the construction code (referring to the Holstein Friesian blood proportion), the season and number of calvings were fixed effects, and furthermore, the year of calving was a covariate. Results and Conclusions. This analysis showed there was no significant difference in the length of service period between the two groups of cows. The total lactation milk yield produced a meaningful difference in performance: single-calving cows had greater milk yield (p=0.013), fat yield (p=0.030), and protein yield (p=0.028) than cows with twins. The milk yield was significantly greater in single than in twinning cows, even when single-calving cows had low milk production levels. This unexpected and contradictory result could be explained by the much longer period of open days in twinning cows, known from previous research Regarding milk yield, an involuntary decrease for cows after twin calving was confirmed.
AB  - Uvod. Blizanački graviditet kod krava holštajnfrizijske rase se javlja u 3-5% slučajeva i uglavnom je praćen reproduktivnim poremećajima i ekonomskim gubicima. Ispitivanja u ovom radu se odnose na evaluaciju i upoređivanje servis perioda i prinosa mleka kod grupe krava sa jednim teletom i grupe krava sa blizancima, na komercijalnim farmama u Mađarskoj. Materijal i metode. Podaci su sakupljani u periodu od 2000 do 2010. godine od ukupno 4223 krava. U Coxovom regresionom modelu (za servis period) i generalnom linearnom modelu (osobine proizvodnje mleka) tip teljenja (jedno tele ili blizanci), kao i sezona i broj teljenja su bili fksni efekti, dok je godina teljenja bila kovarijat. Rezultati i zaključak. Analizom dužine servis perioda nije ustanovljena signifkantna razlika između ispitanih grupa krava. Količina ukupno proizvedenog mleka u laktaciji je pokazala značajne razlike između krava sa jednim teletom i dva teleta, u korist krava sa jednim teletom: prinos mleka (p=0.013), količina mlečne masti (p=0.030) i proteina (p=0.028). Neželjeni pad u prinosu mleka je zabeležen kod krava sa bližnjenjima. Mlečnost je bila značajno veća kod krava sa jednim teletom čak i u slučajevima kada su one imale relativno nisku mlečnost. Ovi oprečni rezultati bi se mogli objasniti činjenicom da su krave koje su se bliznile imale mnogo veći broj otvorenih dana, kao što je to opisano u brojnim predhodnim ispitivanjima.

AB  - Organic production represents a process of sustainable development of the rural areas in
accordance with the available resources and tradition, also implies comprehensive crop and
livestock production, which ensures the preservation and restoration of natural resources,
strongly supports return to the traditional values and knowledges. The new Strategy for
Agriculture and Rural development in Serbia from 2014-2024 defines goals and priorities for
further development of agriculture. One of priority topics is the promotion of organic
production. Sjenica-Pester plateau belongs to High Nature Value region of Serbia and is well
known for its rich biodiversity with favorable floristical composition of pastures and
meadows. Organic sheep production is a perspective opportunity for rural regional
development. Sjenica sheep is one of the most popular transboundry Zackel type, traditionally
reared in the highly mountain regions of Sebia, mainly in the Sjenica Pester-plateu, where it
was originally developed. The finding of favorable content of CLA and n-6:n-3 ratio,
contribute to the advanced phenotypic characterization of Sjenica Zackel sheep type, the
determination of locally adapted breed value and in making a realistic decision for the
promotion of sustainable use of Sjenica Zackel sheep type.
