“…Recent reports in West African taurine and zebu cattle contributed to bridging this information gap (Traoré, et al, 2015;Traoré, et al, 2016). Current research confirms that Kuri cattle are a rarity in the framework of West African taurine cattle (Bourzat et al, 1992). Indeed, all individuals analysed here were humpless cattle.…”

“…It is possible to argue that Kuri differentiation arises because the current work did not include zebu. The continuous unsupervised crossing of Kuri cattle with zebu individuals (Bourzat et al, 1992;Tawah et al, 1997) could have led to an increase in the frequency of qualitative features linked to zebu cattle. This could be supported by the relatively low distance assessed between the Kuri and the Lobi breeds using qualitative-type traits (Table 4).…”

“…Lake Chad is located at the east of the arid Sahel agri-ecological region, between 12°20' and 14°20'N latitude and 13° and 15°30' E longitude, and is bordered by Cameroon, Chad, Niger and Nigeria. Although West African zebu (Bos indicus) cattle are the overwhelming majority in the Sahel area, the overall shape of the breed, including the absence of a hump, has traditionally led to Kuri cattle being classified as a representative of African taurine (B. taurus) longhorn cattle (Bourzat et al, 1992). Unlike the main representative of African taurine longhorn cattle, namely the N'Dama breed, Kuri cattle are not small and are trypanosusceptible.…”

“…A number of reports have highlighted that the Kuri breed is highly endangered. According to Bourzat et al (1992) and Tawah et al (1997), Kuri cattle are threatened by a number of factors, including the difficult political situation of the countries bordering Lake Chad, the shrinking of the lake owing to the increasing duration of the dry season and unsupervised human water extraction, and frequent breeding practices, leading to zebu x Kuri crosses. Using blood groups, lactoproteins, and microsatellites, Souvenir Zafindrajaona et al (1999) reported that Kuri cattle are closer to the West African zebu than to West African taurine cattle.…”

A total of 406 adult cows and 34 bulls belonging to the Niger Kuri cattle population were assessed for 16 body measurements and 11 qualitative traits to contribute to the characterization of this unique cattle breed. Body measurements included facial, horn, ear and rump lengths; facial, cranial, shoulder, pelvic and ischium widths; height at withers and at hips; muzzle circumference; heart girth; body and tail lengths; and thorax depth. Qualitative traits included cephalic profile, ear shape, muzzle pigmentation, eyelid pigmentation, hoof pigmentation, horn colour, dewlap size, backline profile, horn shape, spotting pattern, and coat colour pattern. Data were analysed jointly with 377 individuals from four other West African taurine cattle breeds (N'Dama, Lagunaire, Lobi and Somba) using multivariate statistical methods, including canonical and correspondence analyses. Among the breeds analysed, Kuri cattle had the highest mean values for all body measurements: height at withers and body length had mean values of 124.0 ± 0.4 and 146.8 ± 1.0 cm in Kuri cows, respectively, and 126.0 ± 2.2 and 155.7 ± 3.6 cm, respectively, in Kuri bulls. Canonical analysis allowed the construction of contour plots to illustrate the high differentiation between Kuri cattle and the other breeds, regardless of the sex of the individuals. Further, the Mahalanobis distance matrices showed that pairs involving Kuri cattle had the higher differentiation of these populations. Correspondence analysis carried out on these 11 qualitative traits allowed the researchers to ascertain a clear differentiation between the Kuri and the other taurine cattle breeds. The N'Dama, Lagunaire, Lobi, and Somba breeds did not show clear differentiation at qualitative-type trait level with 75% confidence regions computed for these four breeds being highly intermingled. In the current data, Kuri cattle had the highest frequency in qualitative features, such as concave cephalic profile, dropped ears, non-pigmented muzzle and grey-coloured horns, which are absent in West African taurine and zebu cattle breeds, according to the literature. The current evidence would suggest that unique Kuri cattle type features may result from breeding decisions rather than from zebu admixture. This work confirms that at type trait level Kuri cattle is a unique population within the West African taurine cattle group. The implementation of genetic analyses aiming at ascertaining the degree of uniqueness of the breed is advised.

“…A la station de N'Gouri dans la région du Lac Tchad, les études sur la même race, menées sur une période de dix ans (1948 à 1958) montre que l'âge au premier vêlage varie de deux ans et demi à quatre ans, avec une moyenne de 3 ans et les données recueillies auprès des éleveurs de la région indiquent que 53,5% des vaches dans leur quatrième année ont produit leur premier veau (IEMVT, 1973). Plusieurs auteurs confirment cet âge à la première mise bas entre 3 et 4 ans (Receveur, 1943 ;Malbrant et al, 1947 ;Joshi et al, 1957;Adeniji, 1983 ;Bourzat et al, 1992). Ce résultat est en accord avec l'âge au premier vêlage de 3-4 ans rapporté chez la vache Créole en Guadeloupe en élevage traditionnel (Salas et al, 1988 (Sokouri et al, 2010).…”
