An experiment was undertaken to determine the association between microsatellite marker polymorphisms and phenotypic variation in semen production and cryosurvival traits in bulls. This study contributes to development of database concerning nutritional importance of milk from tropically adapted cattle.Ĭonservation decisions based on neutral genetic diversity have been observed to promote retention of useful quantitative variation in biological populations. Pairwise comparisons based on estimated marginal means were conducted using the least significant difference option.Ĭoncerning coefficient of variation, fat and electrical conductivity have the highest variabilities of 43.29% within milk components and 13.46% within physical properties, respectively. The data were analyzed using general linear model with the univariate procedure. Effects of region of sampling, age, packed red blood cell volume, coat color, number of daily milking, feeding types, and season of milk sampling were investigated.

Milk samples of 233 cows collected during rainy and early dry seasons were analyzed in triplicates with an ultrasonic milk analyzer for nine parameters.

This study comprehensively determined composition and physical properties of the Gambian N’Dama cow milk together with the factors affecting them. Very little is known about food products of tropical cattle.
