WebOct 2, 2009 · Estrous (heat) synchronization in beef cattle involves manipulating the females' estrous cycle so they can be bred at about the same time. The normal 21-day estrous cycle in beef cattle can be altered by following an effective estrous synchronization protocol. Numerous estrous synchronization protocols have been developed that use a … WebCO-Synch + CIDR protocol (Table 2), or Double OvSynch. These protocols take 10 to 17 days to implement, therefore recipient programs need to be scheduled in advance of ovum pick-up for fresh transfers. Heat detection can also be utilized by recording heats and transfer embryos 7 days later. TABLE 1: 7 DAY CO-SYNCH + CIDR PROTOCOL
