Histological analysis of muscles of Landes geese

摘要

The aim of this study was histological and histochemical analyze of imusculus pectoralis major/i (MPM) and imusculus biceps femoris/i (MBF) of 12-weeks old Landes geese husbandry by sex from Hruboňovo (Czech Republic). The geese had live weight of 3979.0?g and the ganders had live weight of 4779.0?g. Higher α White fiber percentage representation of imusculus pectoralis major/i and imusculus biceps femoris/i of 12-weeks old Landes geese histological analyses we followed. Representation of sex identical MBF was 60.0% (gander) and 64.1% (geese) and MPM was 47.6% (ganders) and 51.1% (geese). The lowest α Red fibre percentage content in MPM was 6.7% (ganders) and 4.7% (geese) and β Red fiber in MBF was 10.7% (ganders) and 9.5% (geese). No statistically significant differences (P ≥ 0,05) among sex in the fat cells thickness of geese were found, but significant differences (P ≤ 0,01) was found in MBF fat cells between ganders (26.3?μm) and geese (21.9 μm). Highest thickness of α White fibre in muscles breast and femoral were found in both sex and lowest was found in β Red fibre. Muscles fibres thickness was higher femoral muscles in average (59.9?μm – ganders; 58.3?μm – geese) opposite breast muscles (47.7?μm – ganders, 44.9?μm – geese), what is the mean higher consistence of femoral muscles for consumer. In term of lowest musculus fiber thickness of Landes geese in average were 44.9?μm – MPM, 58.3?μm – MBF opposite of ganders 47.7?μm – MPM, 59.9?μm – MBF. Higher α White fibre representation was both muscles (51.1% – MPM, 64.1% – MBF). We recommended for experience used individual rearing of male.
