We hypothesized that gestational nutrition would affect calf feed efficiency and small intestinal biology, which would be correlated with feed efficiency. Multiparous beef cows (n = 36) were individually fed 1 of 3 diets from d 45 to 185 of gestation: native grass hay and supplement to meet NRC recommendations (control [CON]), 70% of CON NEm (nutrient restricted [NR]), or a NR diet with a RUP s...

Sustainable cowherds require replacement of cull cows either internally via raised heifers or externally with purchased females. Managing raised replacements begins with a weaned heifer calf and continues on through her second pregnancy and calving. Replacement costs were estimated from research conducted in Nebraska for spring-calving cowherds and included the opportunity cost of the heifer ca...

A 3-yr study was conducted with spring-born heifers (n = 240) to determine the effects of developing heifers to either 55 or 60% of mature BW at breeding on reproduction and calf production responses. A concurrent study was also conducted with summer-born heifers (n = 146) to examine effects of breeding heifers with the mature cow herd or 1 mo earlier on reproduction and calf production variabl...

Reproduction incurs a high energetic cost and failure to meet nutritional needs results in reproductive failure. In red deer hinds, the interaction between nutrition, summer lactation and subsequent ovulation/conception is of particular interest for farmed deer production in NZ due to climatic constraints to summer pasture production in many areas. However, few studies have focussed on the pote...

Objectives: Nutrition is often neglected as an important management strategy in Chronic Kidney Disease patients and malnutrition determinant of morbidity mortality. We investigated the energy protein intake Nigerian CKD determined association with malnutrition.Methods: A cross-sectional analysis dietary was conducted using 24hour recall three-day diary records. For malnutrition, anthropometric ...

John M. Marsh (406) 994-5621 [email protected] Profits for U.S. cow-calf producers and cattle finishers depend upon livestock revenues and feed and non feed costs. Some factors that influence profits are subject to management decisions such as technology adoption, health and feed nutrition programs, genetics, and marketing strategies. However, the market components of revenues or costs such as...

Managers spend a majority of their days in face-to-face meetings so it is not surprising that meeting support is becoming an important focus of information technology. But meetings vary wideIy in size, duration, and location. Some are briqf deskside meetings between two or three people, others are lengthy conference room meetings with a dozen or more participants. Thus, support needs may also v...

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...

Performance and economics of calf feeding and feeding long-yearlings was compared from University of Nebraska research conducted from 1996 to 2004. All calves in these studies were spring born and purchased the subsequent fall. The heaviest calves (292 ± 5 kg) were placed into the feedlot and fed an average of 168 d (calf-feds), whereas the lighter calves (239 ± 5 kg) were placed into a long-ye...
