“…Fulani people have also been employed as herdsmen in the SMB system of the current study. Scheper et al (2020) argued that transhumant Zebu keepers, mostly Fulani, contributed to Zebu admixture of local taurine breeds in Sahelian countries. Conversely, the admixture of the TZC population may be interpreted as introgression of taurine genes into Zebu.…”

“…Recently, Houessou et al (2019) confirmed the accuracy of farmers' knowledge in distinguishing cattle breeds in Benin based on morphologic traits. In addition, recent genomic analyses showed very low admixture in animals identified by farmers and sampled as Somba cattle (Scheper et al 2020).…”

West African (agro)-pastoralists have been increasingly using extra-household labour for the management of their cattle herds. This paper seeks to identify the factors influencing cattle owners’ decision to entrust their animals and to analyse the effects of the entrustment practice on the management and sustainable use of the animal genetic diversity within herds. Two hundred and eleven cattle farmers, including absentee-owners (n = 90) who entrusted their animals to professional herders, and owner-managers (n = 121) who look themselves after their cattle, were randomly selected and surveyed in Boukombe district in northwest Benin, the origin of the West African shorthorn Somba cattle breed. Households' socio-economic data and information on herds’ characteristics and management practices were collected using semi-structured questionnaires. The binary logistic regression technique was used to predict the adoption of entrustment by a given farmer in function of his herd’s and household's socio-economic characteristics. Effective population sizes and inbreeding rates for the communal non-entrusted and entrusted Somba populations were estimated and compared. The results revealed that the mode of acquisition of the initial stock, the total livestock units owned and the farmer’s ethnicity were the most important determinants of entrustment. The Somba indigenous cattle breed was threatened in entrusted herds by indiscriminate cross-breeding with Zebus. However, the non-entrusted population appeared to be more exposed to high inbreeding risks. While entrustment represents a good alternative for the efficient use of family labour, adequate strategies are needed to support this practice and encourage herd managers to adopt improved husbandry practices and sound breeding strategies.

“…Sixty-seven animals consisting of 20 Lagune, 20 Somba, 27 crossbreeds (including Borgou and Pabli animals) were selected within a large dataset of Beninese indigenous cattle sampled between 2016 and 2017 [45]. The Lagune and the Somba are two representatives of West African taurine, while the Borgou and Pabli are the products of crossbreeding, i.e., Somba × White Fulani (Zebu) and Somba × Borgou, respectively [6].…”

“…The relationships between the animals were minimized by considering only one sample per herd and per village. In addition, purebred Lagune and Somba animals with respective Lagune and Somba ancestry proportions ≥ 87% were selected, considering the values estimated with Admixture by Scheper et al [45].…”

“…Screening milk protein polymorphisms and genotype composites and casein haplotypes is particularly important in Benin given the increasing crossbreeding and environmental pressures [45,46]. Caroli et al [14] recommended frequent monitoring of milk protein genetic variability in cattle populations to detect and prevent the expansion of undesirable genetic mutations with unfavorable effects on milk traits.…”

This study investigated polymorphisms in the milk protein genes CSN1S1, CSN2, CSN1S2, CSN3, LALBA, and LGB, and casein haplotypes in Beninese indigenous cattle. Considering 67 animals, DNA sequencing of the genes’ exons, flanking regions and parts of the 5′-upstream regions identified 1058 genetic variants including 731 previously unknown. In addition, four novel milk protein variants were detected, including CSN3K (p.Ala66Val), LALBAF (p.Arg58Trp), LGBB1 (p.Ala134Val) and LGBK (p.Thr92Asnfs*13). CSN3K is caused by a novel SNP (BTA6:85656526C>T, exon 4) whereas LALBAF and LGBB1 are due to rs714688595C>T (exon 1) and rs109625649C>T (exon 4), respectively. Regarding LGBK, a frameshift insertion of one adenine residue at BTA11:103257980 (exon 3) induces a premature translation termination resulting in a 46% reduction of the reference protein sequence. The casein polymorphisms formed five main CSN1S1-CSN2-CSN1S2-CSN3 haplotypes including B-A1-A-B, B-A1-A-A and C-A2-A-B which are predominant in the investigated cattle breeds. Moreover, in silico analyses of polymorphisms within the 5′- and 3′- untranslated regions of all six milk proteins revealed effects on microRNA and transcription factor binding sites. This study suggests a large genetic variation of milk protein genes in Beninese cattle, which should be investigated in further studies for their effects on milk production, including quality and yield traits.
