Última Live Animal Ultrasound Information as a Decision Tool in Replacement Beef Heifer Programs AgEcon Dos Santos, Alecsandro; Anderson, John D.; Vann, Rhonda C.; Willard, Scott T.. Real-time ultrasound information taken on beef heifers prior to backgrounding is used to develop a logit model to aid heifer retention decisions. The value of ultrasound data is calculated as the difference in certainty equivalents between a decision rule incorporating ultrasound information and one using only visual cues. The value of ultrasound data is found to be around $10 per head but is influenced by heifer value and backgrounding costs.

Cardoso Neto,Bianor Matias; Barbosa,Larissa Pires; Aguiar,Cristiane da Silva; Souza,Rosiléia Silva; Santana,Ana Lúcia Almeida; Mendes,Claudinéia Silva; Dutra,Patrícia Alves; Leite,Meiby Carneiro de Paula. The substitution of equine chorionic gonadotropin (eCG) by follicle-stimulating hormone (FSH) in protocols for synchronization of ovulation in Santa Inês ewes was assessed. Ten females were submitted to the insertion of intravaginal sponges containing 60 mg medroxyprogesterone acetate for 10 days; after this period sponges were withdrawn and the animals were randomly divided into two groups. Group 1 (n = 5): intramuscular injection of 0.5 mL d-cloprostenol and 300 UI eCG; Group 2 (n = 5): intramuscular injection of 0.5 mL d-cloprostenol and 20 mg FSH. Interval between sponge withdrawal and estrus beginning was 27.7 h and 35.9 h for eCG and FSH, respectively. Interval between sponge withdrawal and the end of estrus was 55.8 h for eCG treatment and 55.6 h...
