Two selection lines of 100 cows each were reared in different management environments. The non-supplemented (NS) line relied on the range throughout the year and w...
متن کاملLameness in Cow/Calf and Feedyard Cattle
The incidence of lameness in beef cows on pasture is generally quite low. Grass pastures are normal walking surfaces for cattle. They provide comfortable forgiving footing that offers traction, thus preventing injuries from slips and falls. Softer walking surfaces also reduce the mechanical factors that encourage claw horn overgrowth and altered weight-bearing that are important predisposing ca...
متن کاملTwinning in cattle: III. Effects of twinning on dystocia, reproductive traits, calf survival, calf growth and cow productivity.
An evaluation of natural twinning in beef cattle revealed that cows birthing twins had shorter (P less than .01) gestation lengths, more (P less than .01) retained placentas, more (P less than .01) dystocia, more (P less than .01) days to estrus, lower (P less than .01) conception rates and more (P less than .01) days to pregnancy than cows birthing singles. Days to estrus, conception rate and ...

متن کاملCOW/CALF MANAGEMENT Minimizing Calving Difficulty in Beef Cattle
Calving difficulty (dystocia) contributes heavily to losses in production in beef cow/calf herds. The obvious losses are due to calves or cows that die at or soon after calving. Less noticeable losses are due to delayed rebreeding, more open females, an extended calving season and increased labor costs. While occasional dystocia is almost unavoidable, through proper management, cattlemen can mi...
