AB  - Investigation of phenotypic and genetic variability of carcass side quality traits and pH values of M. semimembranosusa was carried out on 997 fatteners (446 females and 551 castrates) who originated from 20 sires. Sires were pure breed (Swedish Landrace, Large White and Duroc) and two breed crosses (Duroc x hampshire). In average 48,8 progeny - fatteners over sire were tested. Obtained data was processed by application of several methods of least squares (Harvey, 1990) in which sire genotype, sex and mass of warm carcass sides were included (linear effect) or age at the end of fattening (linear effect). Sires and sex of offspring influenced variation of all traits (P lt 0.01) except on value pH45. Genotype of sire influenced (P lt 0.05) variation of both pH values Heritability coefficients of quality traits of carcass sides were medium and in the interval from 0.234 to 0.408. Low value of heritability coefficient (0.098) was evaluated for trait pH45. Contrary to this trait, heritability of pH24 was high. Phenotypic relation of carcass side traits was of different force (from very weak to complete) and sign. Between traits pH45 and pH24 evaluated coefficient of phenotypic correlation wasn't statistically significant.
AB  - Ispitivanje fenotipske i genetske varijabilnosti osobina kvaliteta polutki i pH vrednosti M. semimembranosusa je obavljeno u 997 tovljenika koji su vodili poreklo od 20 očeva. Očevi su bili čiste rase (švedski landras, veliki jorkšir i durok) i dvorasni melezi (durok x hempšir). Po ocu je ispitano prosečno 48,8 potomaka-tovljenika. Dobijeni podaci su obrađeni primenom nekoliko modela metoda najmanjih kvadrata (Harvey, 1990). Očevi i pol potomaka su uticali na variranje svih osobina (P lt 0,01) sem na vrednost pH45. Genotip oca je uticao (P lt 0,05) na variranje obe pH vrednosti. Koeficijenti heritabiliteta osobina kvaliteta polutki bili su srednji i u intervalu od 0,234 do 0,408. Niska vrednost koeficijenta heritabiliteta procenjena je za osobinu pH45. Fenotipska povezanost osobina polutki je bila različite jačine (od jako slabe do potpune) i predznaka. Između osobina pH45 i pH24 procenjeni koeficijent fenotipske korelacije nije bio statistički značajan.

AB  - Investigation of quality variability of pig carcass was carried out on 1443 fatlings (gilts and barrows). They were progenies of 22 (Farm A) and 12 sires (Farm B), 5 breeds-crossbreds (Swedish Landrace, Large White, Duroc Hampshire, Duroc x Hampshire). Animals were fed with standardized feed mixture semi ad libitum. The quality of carcass sides was determined on the slaughter-line according to Regulation (1985). Investigation included following traits: weight of warm carcass (MTP, kg), meat in carcass sides (KMP, kg and SMP, %), total mass and ratio of leg+shoulder+loin (MFO, kg and UFO, %). Obtained results were processed using several models (Harvey, 1990) which included sire genotype, sire, sex progeny and mass of warm carcass (regression effect). All investigated traits varied under the influence of sire genotype (P lt 0.01) on farm B. The effect of sire genotype was significant (P lt 0.01) on KMP and SMP on the Farm A. All traits of carcass quality varied under the influence of sires. Gilts had higher KMP, SMP, MFO and UFO compared to male castrated heads. Difference in Total Breeding Value between best and worst boar was 10.41 (Farm A) and 11.24 index point (Farm B).
AB  - Ispitivanje uticaja genetskih i negenetskih faktora (genotip oca, otac i pol) na osobine kvaliteta polutki, obavljeno je u 1443 tovljenika koji su vodili poreklo od 5 genotipova očeva. Tovljenici su proizvedeni na dve farme svinja (farma A i B). Dobijeni podaci su obrađeni metodom najmanjih kvadrata (Harvey,1990). Prosečna masa toplih polutki tovljenika sa farme A i B je bila 85,78 i 82,59 kg. Genotip očeva uticao je (P lt 0,01) na variranje svih ispitivanih osobina potomaka na farmi B. Međutim, na farmi A genotip očeva nije uticao (P>0,05) na variranje dnevnog prirasta toplih polutki, ukupnu masu i udeo francuske obrade polutki. Ostale ispitivane osobine (DSL+DSK KMP i SMP) su varirale (P lt 0,01) između genotipova nerasta. Takodje, očevi su uticali na variranje osobina svojih potomaka. Nisu ustanovljena statistički značajna variranja samo osobine DPP između ženskih i muških kastriranih grla (P>0,05). Sve osobine kvaliteta trupa zavisile su od mase toplih polutki (P lt 0,01). Razlika UPV između najboljeg i najlošijeg nerasta na farmi A je bila 10,41 a na farmi B je bila 11,24 indeksnih poena.

AB  - The basic goal of these investigations was to reconsider the hypothesis that year is an important factor which statistically affects phenotypic variability of production traits registered in performance test under conditions of a central test station and make decision to include this effect in models for estimation of phenotypic and genetic parameters which are needed for the genetic evaluation. The investigations were carried out over a seven year period (from 1995 to 2001) in the Station for testing of production capacities of swine at Agricultural Corporation "Beograd" in Padinska Skela. The examinations included a total of 738 tested animals of following breeds: Swedish Landrace, Large White and Hampshire. All three breeds were analyzed together because number of tested boars of Swedish Landrace and Hampshire breed was too small in comparison to the Large White breed. The least squares method was used to test the significance of the effects of year on variability of production traits. Test of significance showed that the year at the start of the test influenced (P lt 0.001) all feed efficiency traits and all growth traits except test duration and average daily gain. The body composition traits were significantly influenced (P lt 0.01 and P lt 0.001) by year except muscle depth. However, it was not expected that the body weight at the start of the test and at the end of the test was influenced (P lt 0.05 and P lt 0.001) by year at the start of the test. The weight at the start and at the end of the test must stay within strict limits proposed by the testing rules. These investigations showed that effect of year should be included in the models that are used to estimate of phenotypic and genetic parameters which are needed for the genetic evaluation of boars tested under conditions of the central station.
AB  - Osnovni cilj ovih istraživanja je bio da se proveri hipoteza o uticaju godine na fenotipsku varijabilnost proizvodnih osobina nerastova u direktnom testu. Sedmogodišnja istraživanja su obavljena u Stanici za ispitivanje proizvodnih sposobnosti svinja, PK "Beograd" u Padinskoj Skeli. Ispitivanjem je bilo obuhvaćeno ukupno 738 grla tri rase svinja i to: švedskog landrasa, velikog jorkšira i hempšira. Sve tri rase su analizirane zajedno imajući u vidu da je broj grla rasa hempšir i švedski landras bio mali u poređenju sa rasom veliki jorkšir. Za ocenu i testiranje hipoteze o uticaju efekta godine na variranje proizvodnih osobina korišćen je metod najmanjih kvadrata. Test signifikantnosti je pokazao da je godina početka testa bila efekat koji je statistički vrlo visoko značajno (P lt 0,001) uticao na variranje svih osobina iskorišćavanja hrane i skoro svih ispitivanih osobina porasta, izuzev trajanja testa i prosečnog dnevnog prirasta. Za osobine kvaliteta trupa ovaj efekat je bio statistički visoko (P lt 0,01 za SL1) do vrlo visoko (P lt 0,001 za SL2 i M) značajan pri njihovom variranju, izuzev za dubinu dugog leđnog mišića. Međutim, ono što nije očekivano je da su i mere telesnih masa statistički značajno varirale (P lt 0,05 i P lt 0,001) pod uticajem godine početka testa, a imajući u vidu da one moraju ostati unutra strogih granica zadatih programom testiranja.
