UTJECAJ SPOLA NA KLAONIČKE POKAZATELJE PAŠKE JANJADI

Cilj ovog rada bio je utvrditi utjecaj spola na klaoničke pokazatelje, mjere trupa, boju mesa mjerenu na svježem presjeku mišićnih regija m. longissimus dorsi (MLD) i m. rectus abdominis (MRA) te kemijski sastav i pH vrijednost mesa janjadi paške ovce. Iako paška ovca pripada skupini pasmina kombiniranih proizvodnih odlika, primarno je namijenjena proizvodnji mlijeka, dok je meso sisajuće janjadi drugi važan proizvod paškim ovčarima za stjecanje dohotka. Glavni razlog klanja mlade i lagane janjadi („sa sise“) na otoku Pagu je raniji početak mužnje i iskorištavanje vrha laktacije za proizvodnju mlijeka koje se uglavnom prerađuje u poznati paški sir. Predmetnim istraživanjem bilo je obuhvaćeno ukupno 112 paške janjadi (66 muške i 46 ženske) zaklane pri prosječnoj dobi od 33 dana. Nije utvrđen statistički značajan utjecaj spola na masu trupa, randman te mase pojedinih unutarnjih organa zaklane janjadi (P>0,05). Unatoč ujednačenoj razvijenosti trupa, trupovi muške paške janjadi bili su statistički značajno dublji od trupova ženske janjadi. Uz to je u trupovima muške janjadi utvrđena niža pH vrijednost mesa i veće L* vrijednosti MLD-a i MRA iako razlike nisu bile statistički značajne (P>0,05). U trupovima ženske janjadi utvrđena je značajno (P
The aim of this paper was to evaluate effect of sex on slaughter traits, carcass measurements, meat colour measured on the fresh section of m. longissimus dorsi (MLD) and m. rectus abdominis (MRA), chemical composition and pH value of meat from lambs of Pag sheep. Although Pag sheep belongs to a group of breeds of combined production traits, it is primarily intended for milk production, while the meat of suckling lambs is another important product of Pag sheep farmers in earning income. The main reason for slaughtering young and light lambs ("suckling lambs") on the island of Pag is the early start of milking and the use of lactation peak to produce milk that is processed in the famous Pag cheese. The research has involved a total of 112 Pag sheep lambs (66 males and 46 females) slaughtered at average age of 33 days. Sex did not have statistically significant efect on carcass weight, dressing percentage and weight of some internal organs of slaughtered lambs (P>0.05). Despite uniform carcass development, carcasses of male Pag lambs were statistically significant deeper then carcasses of female lambs. Besides, in carcasses of male lambs it was determined lower pH value of meat and greater L* values of MLD and MRA, althougr differences were not statistically significan (P>0.05). In carcasses of female lambs it was determined significantly (P
