Characteristics of alpaca wool from farmed animals located on different continents. Interest in breeding alpacas around the world is related to the acquisition of valuable fibre from these animals.The characteristics of alpaca wool are influenced by both genetic and environmental factors.The aim of the study was to compare chosen traits of Huacayaalpaca wool from three farms located in Australia,...
The changes in the milk composition and its lipid fraction during the rearing of lambs in non-milked sheep. Studies regarding the effect of lactation stage on milk content and lipid fraction composition are mostly conducted on milked animals. The aim of this study was to analyze the changes in the basic milk composition and content of fatty acids in the fat fraction during the rearing of lambs in...
Assessment of slaughter value of sheep on the basis of linear measurements made on digital carcass images. The aim of this study was to develop a method of assessing slaughter value of sheep using digital carcass images.Research material consisted of 38 ovine carcasses. Carcasses were classified in the EUROP grading system in terms of muscle and fat and photographed from three sides and then computer...
The adaptability of sheep to harsh environmental conditions makes it possible to obtain valuable products using poor fallow land. However, this requires the selection of an appropriate genotype and stocking density. Both grazing and a diet enriched with vegetable and fish fats increase the content of PUFA n-3 and CLA fatty acids, which are beneficial to human health, in the lipid fraction of milk...
The aim of the study was the comparison of fatty acid composition in longissimus dorsi muscle of ram lambs fattening under overhead shelter versus those in a barn. The maintenance did not influence on main fatty acid composition of muscle tissue. The muscle tissue of lambs reared under overhead shelter compared to these kept in the barn was characterized by significantly higher C10:0, C12:0 (P <...
The aim of this study was the quantitive determination of cis-9, trans-11 isomer by two methods: gas chromatography (GC) and silver-ion high performance liquid chromatography (Ag+HPLC) in ewes milk fat. The study was carried out on 20 ewes of Wrzosówka and Żelazneńska sheep, which were mantained at the same environmental and nutritional conditions. The milk samples have been collected from ewes at...
