AbstractFull Text

The percentage of conception in cows (Bos indicus) of the Sardo Negro breed subjected to a protocol of estrus synchronization and fixed time artificial insemination (FTAI) in Chinameca Veracruz, Mexico, was evaluated. One hundred and fifty eight (158) multiparous cows were used and selected in two...
