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.
Phytophthora root and stem rot of soybean is a destructive disease of soybean in Iran. During 1998-2005, 142 isolates from soil and diseased soybean plants were collected and tested. Race identification was made possible by inoculating Rps differential soybean cultivars and lines. Of the 142 isolates tested, 110 isolates belonged to race 1 and 32 isolates belonged to race 3. Race 1 was dominant in soil and diseased plant samples. There was no variability in virulence of Phytophthora sojae between the areas surveyed.
The aim of this study was to evaluate how training affects plasma total, free and esterified L-carnitine concentrations in horses. The study was done on a total of 32 healthy, trained purebred Arabian horses. The 32 horses comprised two groups. In the first group, 12 stallions and 6 mares three-year-old involved in race-training were studied at rest. In the second group, 14 stallions were studied during a typical race or endurance training session. Jugular venous blood samples were collected to determine lactic acid (LA), free fatty acids, glycerol, triacylglycerides (TG), and the total esterified and free L-carnitine contents. The race training session caused a significant increase in blood LA and plasma esterified L-carnitine, glycerol, and TG levels. It also caused a decrease in the plasma free L-carnitine concentration determined just after the end of exercise. Compared with endurance training, high-intensity racing exercise increased the plasma esterified L-carnitine concentration and decreased that of free L-carnitine according to training intensity.
