To analyze the yield and composition of milk under tropical conditions in Mexico in different genetic groups (Holstein, Brown Swiss, Zebu, Tropic Milking Creole and crosses), a retrospective analysis of 1047 cows (11154 records) in 28 herds located in the central region of the Veracruz State, Mexico was conducted during dry and rainy seasons. The Holstein showed higher milk yield with low percentage composition compared with Zebu and Tropic Milking Creole. Milk yield was significantly high in Holstein cows compared to the other breeds. Among the five genotypes, higher fat and protein percentage was found in TMC. Similarly, lactose, non fatty solids and total solids were significantly high in Z and MTC breeds. Except Holstein, all other breeds produced higher milk yield and composition in rainy season. The data provides a basis for the development of standards of quality specifications for tropical milking cows, establishment of payment systems based on protein and other solids.
