Primena različitih odgajivačko-selekcijskih i biotehnoloških metoda u cilju oplemenjivanja svinja (MPNTR - 31081)

Ključne reči: veličina legla; struktura mišića; mišićna vlakna; porast; svinje
Sažetak
Savremena proizvodnja mesa usmerena je na profitabilnost sa jedne strane uz istovremeno odgovaranje zahtevima potrošača u pogledu kvaliteta mesa sa druge. Isrcpna naučna istraživanja obavljaju se u cilju pronalaženja balansa između količine i kvaliteta mesa. Najveći broj autora slaže se da prasad manje porođajne mase ima manji broj mišićnih vlakana u skeletnim mišićima, sporije raste, kompenzujući mišićni porast povećanjem prečnika mišićnih vlakana i deponovanjem veće količine masti u trupu. Poslednjih godina selekcija u svinjarstvu bila je usmeravana u pravcu povećanja broja prasadi u leglu. Obzirom da je utvrđena inverzna korelacija između veličine legla i mase prasadi na rođenju, cilj ovog rada bio je da se prouče mogući uticaji veličine legla kao faktora na porast svinja i karakteristike m. semitendinosus-a. Osim utvrđene statistički značajne razlike (p=0,05) u broju primarnih vlakana kod prasadi iz malog legla (15053) u odnosu na prasad iz velikog legla (11347), analiza nije pokazala uticaj veličine legla na masu prasadi pri rođenju i druge posmatrane morfološke i histološke osobine mišića. Slično tome, ni kod tovljenika nije utvrđen uticaj veličine legla kao faktora na klaničnu masu, morfološke karakteristike ispitivanog mišića ili na zastupljenost pojedinih tipova mišićnih vlakana u mišiću.
