Induction and Synchronization of Estrus in Dairy and Beef Cattle Breeds by Use of Crestar Preparation
نویسندگان
چکیده
With aim to solve mentioned problems we undertake the induction and synchronization of estrus's by use of "Crestar" (Intervet) preparation in combination with PMSG (Subotica) and prostaglandin's Sinhrogal (ICN Galenika) according to producers recommendation. On the dairy farm 115 cows was treated separately in 4 groups (25, 25, 25 and 40 cows), while on the beef farm were 370 cows in 4 groups (90, 106, 72 and 102 cows). The fourth group in both herds received 15 ml of Minerasol (Verfft Chemie) preparation with minerals.

Development of protocols to manipulate the estrous cycle so all females are in estrus during a short, predefined period (synchronized estrus) while maintaining normal fertility has been a difficult goal to achieve; however, over the past two decades efficacious synchronization protocols have been created and are available to producers today. These protocols have been anticipated for a long time...
متن کاملSynchronizing Estrous in Beef Cattle
Synchronization of estrus contributes to optimizing the use of time, labor, and financial resources by shortening the calving season, in addition to increasing the uniformity of the calf crop. The major limitation of estrus-synchronization programs is their inability to induce a potentially fertile estrus and ovulation in noncycling cattle (i.e., prepubertal heifers and anestrous suckling cattl...
