AB  - The research included a total of 921 lambs, 474 ewes and 8
sjenicke sheep rams from 4 different farms. The aim of the research was to
examine the influence of the farm, cultivation technology and the influence of rams
within the farm on production indicators. Statistical analysis showed that the body
weight of lambs at birth ranged from 3.37 to 4.03 kg (average 3.68 kg), at 30 days
from 11.51 to 12.41 kg (average 12.07 kg) and from 90 days from 27.82 to 29 kg
(average 28.65 kg). A statistically highly significant influence of the farm was
determined (P<0.01) on the body weight of lambs in all three control periods, as
well as on the body weight of sheep and on the fertility of sheep. The influence of
the ram on the body weight of the lambs at birth was statistically very significant
within the farm (P<0.01). When it comes to the percentage share of birth type by
farm, farm 1 had the most singletons (59.13%) both within the farm and in
comparison between other farms, while there were fewer twins (40.87%), and
triplets were not identified. On the other farms, the percentage of twins was the
highest, and triplets were also present, while on farm 4 there were also quadruplets,
lambs born as quadruplets (3.28%).
AB  - Istraživanjem je obuhvaćeno ukupno 921 jagnje, 474 ovce i 8 sjeničkih ovnova sa 4
različite farme. Cilj istraživanja je bio da se ispita uticaj farme, tehnologije gajenja
i uticaj ovnova u okviru farme na proizvodne pokazatelje. Statistička analiza je
pokazala da se telesna masa jagnjadi pri rođenju kretala od 3,37 do 4,03 kg
(prosečno 3,68 kg), na 30 dana od 11,51 do 12,41 kg (prosečno 12,07 kg) i od 90
dana od 27,82 do 29 kg (prosečno 3,68 kg)28. Utvrđen je statistički visoko
značajan uticaj farme (P<0,01) na telesnu masu jagnjadi u sva tri kontrolna perioda,
kao i na telesnu masu ovaca i na plodnost ovaca. Uticaj ovnova na telesnu masu
jagnjadi na rođenju bio je statistički veoma značajan u okviru svake farme
(P<0,01).. Kada je reč o procentualnom učešću tipa rođenja po farmama, farma 1 je
imala najviše jedinaca (59,13%) kako u okviru farme tako i u poređenju sa ostalim
farmama, dok je blizanaca bilo manje (40,87%), a trojke nisu identifikovane. Na
ostalim farmama procenat blizanaca je bio veći a bilo je i trojki, dok su na farmi 4
bila i jagnjad rođena kao četvorke (3,28%).

AB  - Lipska sheep is an autochthonous Serbian population from the
group of Pramenka (Zapfel) sheep, bred in the area around Smederevo, Požarevac
and Mladenovac. The average weight of male animals (BW) is 95 kg and 62 kg of
female animals. Other measurements of female animals are: wither height (WH) 74
cm, body length (BL) 78 cm, chest width (CW) 23 cm, chest depth (CD) 40 cm and
hearth girth (HG) 91 cm. In the last sixty years, adult female animals gained in
average ten kilograms of weight. Other linear measures also increased. The
increase is a consequence of better animal management, especially improved diet.
Since the reduction of the size of the population, larger animals have dominated,
which probably caused the change in the genetic constitution of the breed. Female
animals of Lipska sheep are higher compared to the animals of other fifteen
Pramenka breeds with the exception of Istrian sheep. The area from which Lipska
sheep originates has better soil and richer vegetation compared to the areas of other
Pramenka breeds. Partial correlations corrected for weight between individual
linear measures were positive, with values between 0.196 and 0.814. Most
correlations range between 0.30 and 0.55. Body measurements were studied with
ANOVA on females only. The effect of flock influenced all linear measures with
the exception of CW, whereas the age of animals had no effect on BL, CW and
CD. The increase of individual linear measures was 0.5 to 2.1 mm per kg of BW.
The increase of most body measurements from the first to the fifth year was
statistically significant (P<0.05).
AB  - Lipska ovca je autohtona populacija iz grupe pramenki (Zapfel) koja se gaji u
okolini Smedereva, Požarevca i Mladenovca. Prosečna telesna masa odraslih
muških životinja iznosi 95 kg, a ženskih 62 kg. Eksterijerne mere ženskih životinja
iznose: visina grebena (WH) 74 cm, dužina tela (BL) 78 cm, širina grudi (CW) 23
cm, dubina grudi (CD) 40 cm i obim grudi (HG) 91 cm. U poslednjih šezdeset
godina, telesna masa odraslih ženskih životinja su u proseku povećala za oko deset
kg, što je posledica izmenjenog menadžmenta, pre svega poboljšane ishrane.
Nakon redukcije veličine populacije, dominantne su veće životinje, što je
verovatno uslovilo promenu genetske konstitucije populacije.Područje na kome je
nastala lipska ovca karakteriše plodnije zemljište i bogatija vegetacija u poređenju
sa područjima iz kojih dolaze druge populacije pramenki. Korelacijski koeficijenti
i uticaji stada, starosti životinje u godinama, godine rođenja i težine kod rođenja
odnosno težine izmerene životinje, WH, BL, CW, CD i HG su ocenjeni samo na
ženskim životinjama, obzirom da je bilo obavljeno jedanaest merenja na pet
ovnova. Parcijalne korelacije sa korekcijom na telesnu težinu između pojedinačnih
linearnih mera su pozitivne sa vrednostima između 0,196 i 0,814. Najviše
korelacija nalaze se u intervalu od 0,30 do 0,55. Efekat stado uticao je na sve
linearne mere sa izuzetkom CW dok starost životinja nije uticala na BL, CW i CD.
Porast pojedinačnih linernih mera iznosio je za 0,5 do 2,1 mm na kg BW. Porast
većine telesnih mera od prve do četvrte godine bio je statistički značajan (P<0,05).
