Femoral varus osteotomy (FVO) has been widely used in the surgical treatment of Legg-Calve-Perthes disease (LCPD). Axer in 1965 reviewed FVO as a treatment of LCPD and reported a very favorable results comparing with those observed after conservative treatment. Since then, many authors have demonstrated that it can prevent femoral head deformity and restore spherical congruity, provided that th...

To determine the maternal and reproductive performance of F1 cows in the subtropics, 42 Brahman × Angus, 34 Senepol × Angus, and 50 Tuli × Angus cows were bred to Angus bulls to calve first and subsequently bred to Charolais bulls to calve as 3to 8-yr-olds. Age at first calving did not differ among crossbred cows. Angus-sired calf birth weights were heavier (P < 0.01) from Senepol × Angus than ...

Cost of maintaining heifers varies among farms, but a cost of $1 to $2 per day is common. Scheduling first-calf heifers to calve 2 months earlier saves $60 in feed cos...
