SLAUGHTER CHARACTERISTICS OF CRES, PAG AND TRAVNICKA PRAMENKA LAMBS

Cilj istraživanja bio je utvrditi klaoničke pokazatelje janjadi (klaoničku masu, ma-su toplog trupa, randman te udio pojedinih organa u trupu) creske ovce, paške ov-ce i travničke pramenke, te utvrditi utjecaj pasmine i spola na istraživane klaoni-čke pokazatelje. U tu svrhu zaklano je ukupno 131 janje; od toga 37 (25 muške i 12 ženske) janjadi travničke pramenke prosječne dobi 3,5 mjeseca, 44 creske ja-njadi (22 muška i 22 ženske) prosječne dobi 2,5 mjeseca i 50 paške janjadi (28 muške i 22 ženske) prosječne dobi 36 dana. Navedene razlike u dobi janjadi pri klanju proizlaze iz različitih tehnologija koje se primjenjuju za pojedine pasmi-ne. Klanje janjadi obavljeno je klasičnom metodom obrade koja uključuje iskr-varenje presijecanjem velikih krvnih žila na vratu (v. jugularis externa i a. ca-rotis communis), odvajanje kože i donjih dijelova nogu te vađenje iznutrica. Neposredno prije klanja sva janjad je pojedinačno vagana. Utvrđene prosječne tjelesne mase janjadi prije klanja između pasmina bile su različite (janjad travni-čke pramenke 28,05 kg : 20,02 kg creska janjad : 11,18 kg paška janjad) što je ponajviše posljedica različite dobi janjadi. Također je masa toplog trupa janjadi travničke pramenke bila značajno veća (P<0,01) od mase trupa janjadi drugih dviju pasmina (13,93 kg : 10,74 kg creska : 6,25 kg paška). Utvrđen je značajno veći (P<0,05) randman paške janjadi (55,82%) u odnosu na cresku (53,37%) i ja-njad travničke pramenke (49,49%). Uz to, u janjadi travničke pramenke i paške ovce utvrđen je značajan utjecaj spola na praćene klaoničke pokazatelje (P<0,05). Rezultati ovog istraživanja potvrđuju vrlo izražen utjecaj ovčarske tra-dicije, proizvodnje namjene i navika potrošača na klaoničku masu janjadi, dob janjadi pri klanju i masu trupa.The aim of this work was to determine slaughter characteristics (slaughter weight, hot car-cass weight, dressing percentage and non-carcass components proportion) of lambs from some breeds (Cres sheep, Pag sheep and Travnicka pramenka sheep) offered on Croatian meat market as whole carcass. Also, the aim was to determine the differences in carcass traits between those breeds and lamb sexes. For that purpose, 37 Travnicka pramenka lambs (25 male and 12 female) on average 3.5 months old, 44 Cres lambs (22 male and 22 female) on average 2.5 months old and 50 Pag lambs (28 male and 22 female) on average 36 days old. The differences in age of lambs at slaughter are due to different production system applied for each breed. The lambs were slaugh-tered and processed at local abattoirs in Lika and on islands Cres and Pag. Following slaughter, hot carcasses and ‘’non-carcass’’ components were weighed. The average slaughter weights between Travnicka pramenka lambs, Cres lambs and Pag lambs were significantly different (28.05 kg, 20.02 kg and 11.18 kg, respectively). The hot carcass weight of Travnicka pramenka lambs was signi-ficantly higher than hot carcass weight of Cres and Pag lambs (13.93 kg vs. 10.74 and 6.25 kg). However, Pag lambs had significantly higher dressing percentage than Cres and Travnicka pra-menka lambs (55.82% vs. 53.37 and 49.49%). Also, it was determined that sex had significant influ-ence on slaughter characteristics of lambs from investigated breeds. The results of this research confirm very strong influence of tradition, production goal and habits of consumers on slaughter weight, age and carcass weight of lambs. Primljeno: 15.7.2007
