Increased customer interest of safe, healthy and environmentally friendly food
consumption promote development of sheep farming industry in Latvia. Aim of the paper
–
explain of different pasture
-
fattened sheep breed and their crosses lamb meat composition
traits.
A study of pasture fattened lamb meat chemical composition was carried out from year 2013 to
2017. Fattening lambs were kept in breeding rams control station ‘Klimpas’ (57°50’58.8’’N
25°19’39.6’’E) pasture array. Lambs were slaughtered in a certif
ied slaughterhouse, but analysis
of meat chemical composition were conducted in laboratory of Institute of Food Safety, Animal
Health and Environment (BIOR). For the analysis of the meat chemical composition were used
up to 1
kg
heavy
Quadriceps femoris
mu
scle samples. In meat were analysed following elements
of its chemical composition: dry matter, protein, fat, minerals, pH, cholesterol and unsaturated
fatty acids.
Data analysis shows that the lambs before slaughter ranged in age from 5 to 8 months.
Lamb
meat obtained from the study groups had a significantly different total amount of dry matter
and fat. The lowest total fat, but the highest ash content was obtained in the lamb meat of the
extensive breed group. The lowest total fat and the highest ash con
tent were obtained in the lamb
meat from the extensive breed group.
In meat obtained a small (in individual samples

acid content. Of unsaturated
fatty acids in lamb meat were represented higher amount of oleic acid, linoleic acid and elaidic
acid.
