Histologicalanalysis of muscles of landes geese

The aim of this study was histological and histochemical analyze of musculus pectoralis major (MPM) and musculus biceps femoris (MBF) of 12-weeks old Landes geese husbandry by sex from Hruboňovo (Czech Republic). The geese had live weight of 3979.0g and the ganders had live weight of 4779.0g. Higher a White fiber percentage representation of musculus pectoralis major and musculus biceps femoris 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 a 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 a White fibre representation was both muscles (51.1% - MPM,64.1% - MBF). We recommended for experience used individual rearing of male.
