“…4 and 79.2 cm respectively) for the sheep population in North-East of Algeria. In contrast, the values of these two measurements observed in this study were higher than those recorded by Chellig (1992) for Hamra (70 and 67 cm respectively), Berbère (64 and 60 cm respectively), Barbarine (65 and 64 cm respectively) sheep breed and lower also than those recorded by Kandoussi et al (2021) for the Blanche de Montagne sheep breed in Morocco. The value of BL found in this study was lower than that reported by Khaldi et al (2011) for the sheep breeds in Southern-East of Tunisia, whereas the value of WH was higher than those recorded by the same author.…”

This study aims to characterize the sheep population phenotypically in three zones in northeastern Algeria: Aures, Hodna and Ziban. A total of 160 female animals of 2 to 4 years of age were subject to 4 quantitative linear body measurements (body length BL, withers height WH, tail length TL and wool weight WW) and 9 qualitative physical traits (head length HL, ear orientation EO, horn presence H, neck length NL, wool extent WE, tail texture TT, eyes shape ES, head color HC and wool color WC). The results indicate that the sheep population in these areas belonged to the Ouled Djellel sheep breed with some abnormal phenotypes, which refers to uncontrolled crossbreeding. Body measurements show moderate variation coefficient values, with the highest value reported for WW (7.37%). However, despite the weak correlations found in this study, clear ones were revealed between WH and TL (0.30) and BL and WW (0.26). The Hierarchical Agglomerative Clustering analysis sub-divided the sheep population into three classes, in which an overlap, according to body measurements, was remarked between Hodna and Ziban and between Aures and Ziban but not between Aures and Hodna.

“…The sheep population had a higher value for TL than those reported by Kandoussi et al (2021) for the Blanche de Montagne sheep breed in Morocco (31.1 cm). In contrast, a lower value for TL was found compared to those recorded by Harkat et al (2015) (43 cm) and Dekhili (2014) (38.9 cm) on the same breed.…”

“…Within each sheep breed, healthy sheep individuals raised under similar feeding and management conditions were selected as tested sheep in this study. Morphological characteristics, i.e., body weight, body height, body length, chest circumference, chest depth, chest width, and cannon circumference, were recorded for each sheep in the study [21,22]. On the basis of prior established formulas, body size indices, such as body trunk index (the ratio of chest circumference to body length), body length index (the ratio of body length to body height), chest width index (the ratio of chest width to chest depth), chest circumference index (the ratio of chest circumference to body height), cannon circumference index (the ratio of cannon circumference to body height), and limb length index (the ratio of the difference between body height and chest depth to body height), were also calculated [23,24].…”

Platelet-derived growth factor D (PDGFD) is a member of the PDGF gene family, and it plays an important role in the regulation of adipocyte development in mammals. Furthermore, genome-wide association studies (GWAS) have previously identified it as a candidate gene associated with fleece fiber variation, body size, and the fat-tail phenotype in domestic Chinese sheep. In this study, a total of 1919 indigenous Chinese sheep were genotyped to examine the association between nucleotide sequence variations in PDGFD and body morphology. Our results detected both a 14 bp insertion in intron 2 and a 13 bp deletion in intron 4 of PDGFD. Moreover, these two InDel loci had low to moderate polymorphism. Notably, the 13 bp deletion mutation of PDGFD was found to significantly affect sheep body size. Yearling rams in the Luxi black-headed sheep (LXBH) containing a heterozygous genotype (insertion/deletion, ID) were found to have larger body length, chest depth, and body weight than those with wild genotypes. Furthermore, adult ewes in the Guiqian semi-fine wool sheep (GSFW) containing a homozygous mutation (deletion/deletion, DD) were found to have smaller chest width than their peers. Moreover, yearling ewes in this group with the same homozygous mutation were found to have lower body weight, chest width, and cannon circumference compared to those of other individuals. This study demonstrates that PDGFD InDel polymorphisms have the potential to be effective molecular markers to improve morphological traits in domestic Chinese sheep.

“…This characterization can be achieved through analyses of morphological variation of animals within and between populations. Characterization of livestock breeds based on their morphological variation is a first step toward the inventory of Animal Genetic Resources (AnGR) and is a prerequisite for visualizing the diversity of animal genetic resources and determining their level of genetic erosion [ 11 ]. Animal morphological measurements have diverse implications in breeding perspectives.…”

In Burkina Faso, goats are the second most numerous ruminant livestock population, with almost exclusively indigenous breeds being reared in extensive production systems in various agroecological zones. This study was carried out to understand the morphological variation of local goat breeds in the Sudano-Sahelian and Sudanian agroecological zones. A total of 511 adult female animals belonging to two presumed populations (Mossi breed in Sudano-Sahelian zone and Djallonké breed in Sudanian zone) were sampled and body weight as well as a range of linear body measurements, following FAO guidelines, were recorded. The least squares means of body measurements of indicated that Sudano-Sahelian goats have significantly (p < 0.001) larger body measurements than Sudanian goats. Furthermore, relative high variability of the two populations in morphometric traits was observed. Principal Component Analysis (PCA) suggested structure between Mossi breed on one side and Djallonké on the other side, but no strict separation was observed, suggesting that gene flow is occurring among the different populations. A dispersion map with four clusters was built based on the first two factors. The least square means of body measurements ranked the four groups from small to large body size, namely Djallonké, Mossi × Djallonké, Mossi, and Sahelian × Mossi. Gene flow from Sahelian goat into other populations of the country, based on migration of the Fulani ethnic group from the Sahel into areas with Mossi and Djallonké breeds, could explain this configuration and confirms the continuous erosion of genetic identity of these two local breeds. The sustainable use of these adapted local goat genetic resources calls for the promotion of sustainable genetic improvement using participatory breeding approaches.
