The milk form BO cows in North-Benin seems to be healthier than cow milk from South-Benin for it contained higher MUFA and higher unsaturation indices compared to the BO milk from South-Benin.

The more favorable combination of bovine milk FA composition to human health was suggested to be around 30% SFA, 60% MUFA, and 10% PUFA (Hayes and Khosla, 1992). In the present study, the milk FA compositions were 58.48% SFA, 21.98 % MUFA, 19.56 in BO and 68.19 % SFA, 19.41% MUFA and 12.40% PUFA in WF. It’s clear that the current milk FA composition of BO and WF is far from optimal and there is therefore a need of modifying the FA composition towards the ideal composition. The linoleic acid (PUFA, C18:2 cis-9, cis-12) and oleic acid (MUFA, C18:1 cis-9) have been reported to reduce the risk of coronary heart diseases by decreasing serum total cholesterol and low-density lipoprotein cholesterol levels in humans (Mensink et al., 2003). Oleic acid (C18:1 cis-9) belonging to the w-3 family has anticancer and antiatherogenic properties (Haug et al., 2007 in soyeur et al 2009). The linoleic acid (C18:2 cis-9, cis-12), the most important in the w-6 family reduces the incidence of types 2 diabetes by improving the sensibility to insulin (Hu et al 2001 in soyeur et al 2009). On the other hand, Palmitic acid (C16:0) is considered as hypercholesterolemic, responsible for the increase in quantity of Low Density Lipoproteins (LDL) that are responsible for heart coronary diseases in humans (Rotta et al., 2009). In the present study BO presented milk with higher linoleic acid (P
