The aim of the study was to evaluate the microstructure and elemental compositions of alpaca (Vicugna pacos) hair. The hair from eight alpacas that came from different parts of Poland were analyzed by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). A quantitative analysis was performed for nutritionally important elements (calcium and phosphorous); elements which are part of building blocks of hair structure (silicon and sulfur) and trace elements (copper, zinc, selenium). Moreover, elemental mapping was carried out. The SEM images showed that microstructure of hair is irregular and rough. The average diameter of hair is 32.27 ± 4.06 µm. The obtained results showed content of elements in hair and also their distribution in the structure of hair. These findings can be a good benchmark for further studies.
Alpacas are known worldly for their very fine, luxurious fiber which is three times more hardy and six times more thermal than sheep fiber. Aside from fiber, alpacas are also bred for meat and used in the tourism and recreational industry and animal assisted therapy. Possibility of comprehensive use of these animals caused alpacas' popularity to grow immensely over the past few decades all over the world, also in Poland, where they adapted very well and have been bred since 2004. The objective of the analysis was to study the stocks of the Polish alpaca population, sex structure, also interesting was the inquiry of the distribution of various fleece colour. In Poland the majority of alpaca breedings are concentrated in voivodeships: Silesia, Podlasie and Wielkopolska. According to questionaire surveys carried out in 2012 on 9 farms, alpaca population in Poland numbers 651 and consists of: Suri (12%) and Huacaya (88%) which differ in coat type. In the surveyed population 86% consituted females and 14% males, in Suri population, 65% consituted females and 35% males. Alpaca fleece occurs in 22 natural colours, all shades of beige, brown and grey. Distribution of coat colour in the surveyed population, according to the method-oligically amended criterium was established as follows: white 58%, fair brown 12%, dark brown 9%, cream-coloured 6% and grey 6%, black 5%, multicoloured 4%. In the surveyed population of Huacaya alpacas the majority consituted white-couloured animals (63%), fair brown-coloured - 11%, dark brown-coloured - 8%, grey and black - 5% each, multicoloured - 3%. The Suri population was dominated by cream-coloured animals, whereas fair brown-coloured and dark brown-coloured cosituted 20% each, white-coloured - 12%, grey, black and mulitcoloured - 9% each. Results obtained can be considered satisfying compared with results obtained in Peru, where the biggest alpaca population is.
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, Africa and Europe.The wool samples were collected from 30 alpacas, 10 from each farm the assessed wool characteristics included: fibre diameter, level of medullation and staple length was determined. The following fibre types have been identified: with continuous medulla, with partial medulla and no-medullated.Similar results were obtained with respect to the fibre diameter, staple length, the level of medullation and even distribution of the type of medullated fibres in all tested farms.
