“…In accord-ance, Purwantini et al (2013 b ) stated that local duck crossbreeding may have generated the high variability in the mtDNA D-loop region as seen in the Indonesian duck population. Further, high genetic diversity indicates that the population hasn't experienced either population expansion or selection, as well as human exploration activities in the particular area, thus the population still preserves its genetic uniqueness (Adebambo et al, 2017). On the contrary, the π value is denoted as low (Table 3).…”

Magelang ducks (MD) are Indonesian local ducks and are known as dual-purpose type ducks which have high egg production, duck day production (DDP), and body weight size. Nowadays, the MD is selected to establish the pure line to advance the egg production trait in the Breeding and Rearing Center of Non-Ruminant Animals Banyubiru, Central Java. The mitochondrial DNA (mtDNA) Dloop region, is highly polymorphic and could be used to analyze the population genetics. The present research aims to examine the impacts of continuous selection on population structure and genetic mutations on MD across two generations using the mtDNA D-loop region. Thirty-six blood samples from the second (G2) and third (G3) generations were examined using the sequencing method. The MEGA X and DnaSP software were applied to calculate the genetic diversity, genetic distance, and to generate a phylogenetic tree. The number of haplotypes (H), haplotype diversity (Hd), and Tajima's D are 26, 0.9746, and -1.46, respectively. The Fst value of MD is 0.156. The genetic distance among populations ranges from 0.0000 – 2.097. The UPGMA analysis constructs one clade in a phylogenetic tree between MD, Indonesian local Ducks, Indian Ducks, Vietnamese Ducks, and Chinese Ducks. The study found that the genetic variation and population structure did not significantly change between the second and third generations.

“…Reports of recent studies by Adeola et al (2020;2022) revealed low genetic diversity between and within Nigerian Muscovy ducks. In another study, Adebambo et al (2017) equally reported a relatively high genetic diversity and differentiation among Nigerian ducks using the mitochondrial DNA (mtDNA) D-loop region. Likewise, Ogah et al (2017) equally discovered low genetic diversity in Nigerian Muscovy ducks using the mitochondrial D-Loop sequence while Sola-Ojo et al ( 2021) reported a wide genetic merger among Nigerian Muscovy ducks while using the nuclear DNA CYP2U1 gene.…”

Research, development, and breeding of ducks in Nigeria are on the rise and continuous breeding of ducks needs basic information on their production environment, genetic background, and diversity. Nigerian local ducks (NLD) have been phenotypically characterised based on morphological characteristics which have provided a reasonable representation of their genetic difference. Morphological and morphometric variations exist among indigenous ducks of Nigeria and mottled plumage colour is preponderant. Low genetic diversity exists among Nigerian duck populations implying that ducks are in close genetic relationships irrespective of distinctive and varying phenotypic, biochemical, and physiological characteristics, whereas the phylogenetic tree revealed clustered relationships. Large-scale duck farming is uncommon; rather, ducks are kept as a pastime business. The scavenging feeding system is majorly practiced among small flock sizes which are highly predominant. NLDs lay between 100 and 125 eggs yearly when reared under an intensive system of management and also have a high hatching rate of above 70% even though high environmental temperature affects their reproductive performance. There are no organised duck markets in Nigeria. Duck eggs are rarely consumed or sold; rather they are majorly used for breeding purposes. Myths, poor funding, lack of standard laboratories, and lack of skilled workforce are among the factors affecting the development and conservation of indigenous ducks in Nigeria. Introducing improved breeds of duck and establishing conservation programmes will help promote greater duck production and conservation. Duck business is a profitable but seasonal business and can efficiently bridge the noticed protein gap in rural communities.
