Impacts of Estrous Synchronization on Cowherd Performance

Estrous Cycle Synchronization In

E STRUS and ovulation in gilts have been successfully inhibited by daily injections of progesterone (Ulberg et al., 1951; Baker et al., 1954) and more recently by the inclusion of progestational compounds in the feed (Nellor, 1960; Dzuik and Baker, 1962). The successful use of orally active progestational agents to synchronize the estrous cycles of gilts without a subsequent reduction in fertil...

Physiology and Endocrinology : Estrous Synchronization

47 NC and AC1 treatments (P<0.05). N digestibility was higher in both PC and AC3 treatments compared with NC and AC1 treatments (P<0.05). The RBC count was increased in ALA treatment compared with NC treatments (P<0.05). Hemoglobin in AC2 treatment was higher than NC treatment (P<0.05). Lymphocyte, WBC, IgG and total iron binding capacity were not affected among all treatments (P<0.05). The red...

Review of Estrous Synchronization Systems : Cidr

The CIDR is an intravaginal progesterone insert, used in conjunction with other hormones to synchronize estrous in beef and dairy cows and heifers. The CIDR was developed in New Zealand and has been used for several years to advance the first pubertal estrus in heifers and the first postpartum estrus in cows. The CIDR is a “T” shaped device with flexible wings that collapse to form a rod that c...
