“…However, by using the same analysis Salamena et al (2007) showed that the Kisar sheep in Maluku had not yet established a new sub-population. Similar results were also shown for Central Java local buffalo (Johari et al, 2009) and Maluku local buffalo (Salamena and Papilaja, 2010), several sub-populations were observed could not be differentiated and therefore had not formed a new sub-population.…”

This research was carried out to make a difference and to predict genetic distance some sheep that are genetically related to each other based on the body size measurements. Nineteen bodies size of 323 sheeps of five sheep breeds; namely Barbados Black Belly Cross (BC), Garut Local (GL), Garut Composite (GC), Sumatra Composite (SC) and St. Croix Cross (SCC) were measured. Analysis of variance and canonical discriminant analysis, Mahalanobis distance, plotting canonical and dendogram were performed using PROC GLM, PROC CANDISC, PROC CLUSTER and PROC TREE of SAS software ver. 9.0. Index Length, Width Slope, Depth Slope, Balance and Cumulative Index of GC sheep were significantly higher than the four other breeds. Canonical discriminant analysis successfully could differentiate among the five sheep breeds. All five breed were divided into two groups: the first group consisted of SCC, SC and BC; and the second group consisted of the GL and GC. The results of genetic distance estimation showed that the SCC had a value of sheep genetic distance closest to SC (10.83) and BC (27.98), while GL had the closest distance to GC (66.60). The tail width, horn base circumference, horn length (canonical 1) and variable length of the tail and body length (canonical 2) were the breed differentiation variable in this study.

“…Both regions are geographically adjacent to each other. Therefore, free migration and mating can occur between both nearby populations (Johari et al 2009). The genetic relationships between the buffalo groups are consistent with their biogeographic origins (Winaya et al 2019).…”

“…Due to their near geographic position, two or more populations can be grouped into a single cluster (Abinawanto et al 2018). Johari et al (2009) stated that all buffaloes from the nearest regions showed the same position based on canonical structures. This is related to the genetic relationship of the buffaloes, which were assumed to originate from the same ancestor by marriage.…”

Abstract. Murni D, Lestari U, Indriwati SE, Efendi A, Maryani N, Amin M. 2020. Morphometric diversity and phenotypic relationship among indigenous buffaloes of Banten, Indonesia. Biodiversitas 21: 933-940. This study aimed to describe the morphometric diversity and phenotypic relationship among indigenous buffaloes of Banten, Indonesia. In this study, 125 buffaloes from six regions were investigated based on 11 morphometric characters. Morphometric diversity was analyzed using multivariate discriminant analysis. The Euclidean genetic distances were used to estimate the phenotypic relationship among the buffalo populations. The indigenous buffaloes of Banten have high morphometric diversity, with a coefficient from 2.83 to 41.43%. The body length and chest circumference can be used as a morphometric marker to determine potential indigenous buffaloes as their high correlation coefficient value (0.506). The Serang district buffaloes have the highest mean of body length and chest circumference, which shows that this population is potential compared to the populations from other regions. The morphometric of buffalo population from Serang City, Cilegon City, Serang District, and Pandeglang District tend to be homogenous. Meanwhile, Lebak and Tangerang District population tends to heterogeneous. According to Euclidean distance analysis, the proximate phenotypic relationship was between Serang and Pandeglang District's buffalo populations. Our results indicated that morphometric diversity and phenotypic relationships of the populations were related to geographical origins and can be used to determine the potential indigenous of buffaloes.

This investigation aimed at evaluating sexual size dimorphism in Uda sheep using multivariate discriminant analysis. Eleven morphological traits were measured on a total of 296 adult sheep of both sexes randomly selected in Nasarawa State, northcentral Nigeria. The univariate analysis showed that Uda rams had significantly (P B0.05) higher values in nine of the morphological traits examined. Measurements that were best able to separate the rams and the ewes as revealed by the canonical discriminant analysis were head width and face length. These two variables were included in the single discriminant function used to classify the two sexes. The discriminant model was able to allocate correctly 70.8% of Uda ewes and 58% of rams to their a priori sexes. Ward's option of the cluster analysis further revealed the morphological distinctness of the population. The discriminant function obtained in the present study could be useful in management, ecological and conservation studies.
