Influence of litter size on growth and structure of m. semitendinosus in newborn piglets and slaughter pigs
Uticaj veličine legla na porast i strukturu m. semitendinosus-a kod novorođene prasadi i tovljenika
Abstract
Modern meat production has to meet the requirements of profitability, while meeting the demands of consumers in terms of meat quality at the same time. Huge scientific work has been done in order to find balance between quantity and quality of meet. Most authors agree that piglets of lower birth weight have less muscle fibers within muscle, grow slower, compensating the muscle growth with increase of muscle fiber diameter and accumulating carcass fat. In recent years, selection in pig production has been directed towards increase of piglet number per litter. Since the inverse relation of litter size and birth weight has been well documented, the purpose of this work was to investigate the possible effects of litter size as a factor on pig growth and m. semitendinosus characteristics. Except the statistically significant difference (p=0,05) in number of primary fibers among piglets from small litter (15053) and large litter (11347), litter size did not influence birth weight, or other o...bserved morphological and histological characteristics of the muscle significantly. Similarly, results of this research show that litter size as a factor did not affect final weight, morphological characteristics or fiber type distribution within the muscle in slaughter pigs.
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 pokaz...ala 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.
