Differentiation of some Pramenka sheep breeds based on morphometric characteristics

Abstract

For the purpose of the morphometric characterization and differentiation of local sheep breeds that belong to the group of breeds called Pramenka or Zackel, two Slovenian (Bela Krajina and Istrian Pramenka) and four Montenegrin sheep breeds (Bardoka, Sjenička, Pivska Pramenka, and Zeta Žuja) were studied. The variation of morphometric measures and nine morphometric indices were analysed. Principal component analysis (PCA) was applied in order to provide an easier description of body size and shape. Regarding body size, the Sjenička breed was one of the largest breeds (body weight 76.4 kg, wither height 72.7 cm, chest circumference 100.3 cm), while Zeta Žuja had the smallest body size (37.1 kg, 64.8, and 81.9 cm). On the other hand, Slovenian Istrian Pramenka had the largest body length, chest depth, chest width, and rump width among all included breeds (79.4, 33.6, 22.7, and 21.2 cm). Bela Krajina, Istrian Pramenka, and the Sjenička breed, according to the index of body frame (IBF) value (107–114), have a rectangular body frame, Bardoka and Pivska Pramenka have a square body frame (99.3–100), and Zeta Žuja has a short body frame (91.8). The PCA of all morphometric parameters extracted three components accounting for 96.6 % of the cumulative variance. An unweighted pair–group method with arithmetic mean (UPGMA) cluster analysis by Euclidian distance shows diversity among the studied breeds, through it grouped Pivska Pramenka with Sjenička and Istrian with Bela Krajina Pramenka in two clusters, while Bardoka and Zeta Žuja were clustered separately.

Effect of activated clinoptilolite and inactive brewer’s yeast mixture on loin eye muscle and body indexes in fattening period

“…The same researchers found the index of compactness in Cornigliese sheep breed as 84.24 in the males at the age of 0-6 months. Another study clearly showed that the breed type significantly affected IA (13). Considering the differences in terms of the fattening parameters versus characterization of breeds, the results of our study were in accordance with those of the studies in the literature.…”

“…Body measurement indexes. Both the ethnological and functional indexes which contribute to the breed characteristics, type, purpose, and performance were calculated as follows (4,11,13,17,19). Ultrasound measurements.…”

Morphometric characterization of Kacang goats raised in lowland and highland areas of Jambi Province, Indonesia

“…It can be suggested that Kacang goats at this location have the different of morphometric traits rather than the other regencies.. Previous studies obtained a Euclidean distance of 1.87–8.87 among Pramenka sheep from six different populations in Slovenia [ 7 ] and of 2.34–7.77 among Black Creole goats from seven diverse communities in Mexico [ 13 ]. The differences in animal management, selection, geographical area, agro-climatic conditions, and natural resources can be affected by phenotypic variation among breeds from different populations.…”

“…No studies on the morphometric characteristics of Kacang goats in Jambi Province have been published recently. Breed characterization in goats and sheep can be carried out based on body measurements and body indices [ 4 – 7 ]. Hence, morphometric characteristics can characterize goats and sheep from different populations [ 8 – 13 ].…”

IDENTIFICATION OF INTERSPECIFIC HYBRIDS ARGALI (Ovis am-mon) AND DOMESTIC SHEEP (Ovis aries) OF DIFFERENT GENERA-TIONS BY EXTERIOR INDICATORS

“…Морфометрические параметры также применяются для косвенной оценки живой массы и направления продуктивности животных (17), отбора и подбора по экстерьеру (18). Изучение морфометрических параметров в течение длительного периода позволяет дать характеристику структуры породы и популяции, а также направления селекции за определенный промежуток времени (19).…”
