Аннотация
A growth experiment with 108 lambs (breed German Merino Landsheep) was
carried out in order to examine how gender, body weight and feeding
intensity affect trace element concentrations in tissues and carcass.
The lambs (50% male and 50% female) were fattened at three levels of
feeding intensity (�low�, �medium� and �high� by varying daily amounts
of concentrate and hay) and slaughtered at different final body weights
(30, 45 or 55 kg). Six male and six female animals were sacrificed at
18 kg live weight at the beginning of the comparative slaughter
experiment. The left half carcass of each animal was divided into
muscle tissue, fat tissue as well as bones and sinews and analysed for
the trace elements copper (Cu), iron (Fe), manganese (Mn) as well as
zinc (Zn). The body weight level influenced the Zn concentrations
significantly in all tissues. In addition, the Fe concentration in the
fat tissue was influenced by the body weight as well as the Cu content
in the bone tissue. An influence due to gender could be seen for the Zn
concentration in the muscle and fat tissue and for the Fe content in
the fat and bone tissue as well as for the Cu concentration in the
bones. The feeding intensity affected the Cu content in the muscle and
bone tissue and also the Zn content in the muscle tissue. In the
present study with lambs at body weight range from 18 to 55 kg on an
average, 127 mg Fe, 87 mg Zn, 1.5 mg Cu as well as 1.1 mg Mn per
kilogram dry matter were found in the bone tissue. In lamb muscle
tissue combined from all parts (body weight range from 18 to 45 kg,
both genders) the highest concentrations were for Zn and Fe 3.42 and
1.31 mg/100 g meat (wet weight basis), while Cu remained far below
these levels (0.08 mg/100 g meat and Mn was even below the detection
limit of 0.025 mg/kg). Lamb muscle is a valuable source for highly
available haem-Fe as well as for Zn and Cu in human nutrition.
