Comparative finite element analysis of the first thoracic vertebra in artiodactyls

Journal of Morphology, Volume 285, Issue 5, May 2024.
Using finite element analysis, this study explores the morphology of the first thoracic vertebra (T1) and its performance under compressive and tensile loads in artiodactyls with different neck postures and body sizes. Species with an upright posture exhibited the lowest stress and therefore performed better than species with a suspensory posture under

Left displacement of the third gastric compartment in an alpaca: the first case report in China

BMC Veterinary Research, 2022
Background Left displacement of the third gastric compartment (LDC3) in alpacas is an extremely rare condition and has not been reported thus far. Therefore, we describe the clinical diagnosis and treatment of LDC3 in an alpaca.

Optimal sampling interval for characterisation of the circadian rhythm of body temperature in homeothermic animals using periodogram and cosinor analysis

Ecology and Evolution, Volume 14, Issue 4, April 2024.
The circadian rhythm of core body temperature is an indicator of the physiological state of a homeothermic animal and can be used as a biomarker of its fitness to its environment. In this study, we investigate the impact of sampling intervals used to collect body temperature data on cosinor estimates of the circadian rhythm, and discuss the optimal ...

Characterization of paneth cells in alpacas (Vicugna pacos, Mammalia, Camelidae)

Tissue and Cell, 2016
Paneth cells are secretory epithelial cells of the innate immune system of the intestine of several mammals, including alpacas. Little is known about the latter; thus, in the present study we described the morphology and histochemical characteristics of Paneth cells in healthy fetuses, and young and adult alpacas. For this purpose, samples of duodenum,

Animal domestification [PDF]

, 2010
Domestifikacija životinja je jedan od najznačajnijih događaja u ljudskoj povijesti. Omogućila je prijelaz iz lovačko-sakupljačkog života u sjedilački, a to je vodilo prema brzom napretku čovječanstva.

Identification of genomic regions associated with differences in fleece type in Huacaya and Suri alpacas (Vicugna pacos)

Animal Genetics, Volume 55, Issue 1, Page 163-167, February 2024.
Abstract The difference in fleece type is the distinguishing trait between the two types of alpacas (Vicugna pacos), Huacaya and Suri. The Suri fleece type has been found to be inherited dominantly over the Huacaya type, resulting in offspring with the Suri phenotype.

Rasplođivanja mužjaka alpaka (Vicugna pacos, L.)

Veterinarska stanica, 2018
Alpake su pripitomljene životinje iz porodice deva koje potječu s južnoameričkih Anda. Fiziologija rasplođivanja alpaka se znatno razlikuje od nama poznatih domaćih životinja. Rasplodna sezona u Južnoj Americi traje tijekom kišne sezone, od prosinca do ožujka, dok se u Sjevernoj Americi pare čitave godine. Spolno su zreli u dobi od 1 do 3 godine.

Effect of genotype and sex on fiber growth rate of alpacas for their first year of fleece production

, 2014
The sale of alpaca fiber is the main income for thousands of families in the Central Andes of Peru. Little information exists on the fiber length growth rate of alpaca (FLG), especially throughout their first year of life when the fiber is most valuable.
