The n’dama cattle are a smaller sized animal with compact body. They are usually of fawn colored, but their coloration can vary from sand to black color and sometimes spotted. Their back is fairly broad, well-fleshed and straight from withers to tail head.
Study was carried out to assess the current genetic diversity and the phylogenetic relationships of the four native senegalese cattle breeds (gobra zebu, maure zebu, djakoré, and n’dama). Methods: genomic dna was isolated from blood samples of 120 unrelated animals collected from three agro-ecological.
International research conducted by ilri in nigeria, the democratic republic of the congo and kenya has shown that the n'dama is the most resistant breed. In nigeria, research has shown that n'dama is up to 2-3x (or 25%) more resistant than nguni cattle.
N’dama cattle possess certain potentials such as disease tolerance, coat colour, special service and products which would enhance the resilience of smallholder livestock farmers. The findings of this study will properly inform future policy design and implementation.
The senepol cattle are actually an admixed breed between an european taurina (red poll) and zebu. Genetic characterization using high throughput snp genotyping recently demonstrated that the senepol genome contains crosses between european taurine with some zebu influence.

This makes n’dama a valued animal in africa’s endemic regions, although the breed tends to be smaller, produce less milk.
Crossbreeding the trypanotolerant n'dama cattle and the trypanosusceptible zebu cattle is a new trend in west-africa.
Meanwhile, the relative high number of n'dama cattle in the developing countries like the gambia, guinea, southern senegal, guinea-bissau, mali, liberia, sierra leone, congo and gabon is related to its distinguishable disease tolerant abilities, relatively high adaptability to prevailing local climatic conditions, conservative nature of the farmers, traditional and socioeconomic importance attached to the animals.

Origin and distribution: the n'dama, also known as boenca, boyenca, and faouta longhorn, is a humpless longhorn (bos taurus longifrons). Until recently, humpless (bos taurus) hametic longhorn cattle breeds are believed to have descended from the first domesticated cattle populations of the humpless hamitic longhorn cattle in the region's so-called the 'fertile crescent', possibly 9000 bc (payne.
