AFS breed of tropical dairy cattle has been developed to combine the high milk production characteristics of the Bos taurus breeds with the tropical adaptation characteristics of the Bos indicus breeds. Early selection was based on the elimination of cows which failed to let down milk in the absence of the calf. Subsequent selection involved the development of a progeny testing programme for AFS bulls. A multiple ovulation and embryo transfer (MOET) programme was established in 1985 to further develop the breed. Details of this MOET programme are described.
