ABSTRACT
The experiment was conducted at the Center of Biotechnology and Animal Reproduction (CEBRANUFPa),in the municipality of Castanhal, Pará State. The herd consisted of 24 crossbred cows with bodycondition score ranging between 2.5 and 3.5, divided randomly into 2 groups (G1 and G2) which were managedwith different protocols. G1 (D0-Be+P4 implant; D7-Pgf2; D9-measurement of the largest follicle + CE + eCG;D11- new measurement of FD and D15- verification of the presence or absence of CL and its measurement) G2(D0-Be + P4 implant, removal of implant D8 + FSH; D9- BE; D10-measurement of FD; D14- verification of thepresence of CL). Therefore, is possible the identification and selection of animals subjected to thesynchronization protocol for IATF.(AU)

The beef cattle industry in Brazil is characterized as an activity that goes through a period of growth.The experiment was conducted at the Center of Animal Reproduction Biotechnology (CEBRAN-UFPA), in themunicipality of Castanhal, Pará State. The herd consisted of 24 crossbred cows with body condition scoreranging between 2.5 and 3, 5, divided randomly into 2 groups (G1 and G2) which were managed with differentprotocols. G1 (D0-Be+P4 implant; D7-Pgf2; D9-measurement of the largest follicle + CE + eCG; D11- newmeasurement of FD and D15- verification of the presence or absence of CL and its measurement) G2 (D0-Be +P4 implant, removal of implant D8 + FSH; D9- BE; D10-measurement of FD; D14- verification of the presenceof CL). In the present study was not observed statistical difference for the size of follicular diameter at themoment of TAIF and CL formed in different synchronization protocols.(AU)
