“…Determined heritability values for body weight at birth are consistent with the values reported by Perez et al (2017) in Katahdin breed (0.07±0.0015), Boujenane and Diallo (2016) in Sardi sheep (0.07±0.02), Ozcan et al (2005) in Turkish Merino sheep (0.08), Kastelic and Kompan (2007) in lambs of Jezersko-solcavska breed (0.078±0.035) and with Haile et al (2018) who determined low heritability values during mating between Syrian and Turkish Avasi sheep (0.03±0.022 and 0.06±0.042). Medium heritability values for this trait were determined by Baneh and Ahmadpanah (2018) for local Iranian Ghezel breed (0.285) and by Murphy et al (2018) 0.27 in crossbreds obtained by crossing the sheep dairy breed (Eastern-Friesian and Lacaune breed).…”

The objective of this research paper was to estimate heritability coefficients (heritability) of growth traits in the lambs of indigenous Sjenicka Pramenka breed. The research was conducted on a sample which included 421 lambs the descendants of 15 sires and 187 sheep-dams, raised on 3 private farms in Kolubarski district, Serbia. The effect of fixed factors was studied while the values of heritability coefficients were estimated within the frame of SAS software package. A statistically highly significant (**=P<0.01) effect on studied traits had following parameters: sex, year of lambing, type of lambing, farm and method of applied reproductive technology. By means of REML method and using the sire model the values of heritability coefficients were determined for the following traits: average lamb birth weight (BW0), average lamb body weight at 30 days (BW30) and average lamb body weight at 90 days (BW90) being: 0.0355; 0.4642 and 0.3018, respectively.

“…Both populations are mainly suited for lamb production in the Alpine and pre-alpine region where they stay on Alpine pastures in summer. Despite year-round lambing the fertility traits of recorded JS and JSR flocks have been decreased in recent years (Kastelic and Kompan, 2007). One possible explanation for the reduction of production in JS and JSR flocks was thought in the differences in rearing technologies (Cividini et al, 2009;Petrović et al, 2009).…”

The study contains the result from the test f the vacuum - packed meat sliices ( M.quadriceps femoris) obtained from ox Simmental breed. After the primary treatment, the refrigeration an the sorting out , the meat slices were vacuum -packed and kept and a temperature of 4?C and 6?C. At the 2nd, the 3rd and the 5th day, a chemical analysis of the meat slices was made. At the 2nd and the 5th day it was made a microbiological test of the meat slices in relation to the overall number of bacteria, as well as a sensor analysis in terms of outward appearance, consistence, color, odor and taste. It was noted that, during the storage the water content in the meat slices significantly reduced, and the fat, protein and mineral substance content was increased. The overall number of bacteria was increased in the meat slices kept at a temperature of 6?C. The best sensor marks were given to the meat slices kept at a temperature of 4?C.

In Slovenia low and medium production systems are prevalent in sheep breeding. The rearing technology depends on a large number of factors. The main factors affecting the choice of rearing technology are sheep breed, local conditions, season of mating and weaning time. In the present study the rearing technology in sheep breeding was analysed. This analysis included the results of 293 questionnaires from sheep breeders of autochthonous Jezersko-Solčava and Improved Jezersko-Solčava breed. Data were subjected to the frequency analysis, using the FREQ procedure of the SAS Statistical Software (1990). The population size in the flocks of these breeders was mostly from 5 to 50 animals (73.3%). The lambing system is year-round (80%) and seasonal (7.5%). The wanted litter size of 47% of breeders is just one live born lamb. Breeders weaned their lambs at 60-90 days of age or even later. Lambs stayed with their mothers almost till the end of lactation (16-20 weeks) or till the sale to the market when they weighted 30-35 kg. Early spring and summer born lambs stayed with their mothers on the pastures with no supplement. Winter born lambs stayed with their mothers in the stable, fed by hay and supplement (cereals or commercial concentrate). The rearing technology used by Slovenian sheep breeders is sustainable and gives the opportunity for conservation of autochthonous breeds in the original environment.
