Succession Planning And Perceived Obstacles And Attractions For Future Generations Entering Beef Cattle Production, Lee L. Schulz, Georgeanne M. Artz, Patrick J. Gunn
Succession Planning And Perceived Obstacles And Attractions For Future Generations Entering Beef Cattle Production, Lee L. Schulz, Georgeanne M. Artz, Patrick J. Gunn
Journal of Applied Farm Economics
This study provides valuable insights into cow-calf producer and feedlot operator succession plans for transferring cattle operations upon exiting the industry. Across both cow-calf producers and feedlot operators, about 50% expect to be raising cattle for 10 more years or less; however, about 39% of these producers do not have a succession plan in place. Cow-calf producers view a rural lifestyle, self-employment, working with livestock, and working with family as the biggest attractions to future generations entering beef cattle production. Cow-calf producers view environmental regulations, land tax policy, and expansion of corn and soybean acres as the biggest obstacles. Feedlot …
The Difference Between Two Implants And No Implants In Nebraska Steers, Bailie Boyce
The Difference Between Two Implants And No Implants In Nebraska Steers, Bailie Boyce
Undergraduate Research Journal
A small-pelleted implant placed under the skin on the back of the ear of a calf can help increase average daily gains (ADG) by 10-20% when compared to non-implanted calves (Payne 2012). As a result of increased feed efficiency from the implant(s), less feed is needed, which in return decreases the costs of production by 5-10% (Payne 2012). Implants can influence weight gain in cattle, resulting in an overall increase in beef supply for producers. Implants work by slowly dissolving under the skin to release a small amount of artificial hormones daily anywhere from 60 to 120 days. They are …

Genetic analysis provides producers with another tool to identify individuals in a herd which have the greatest potential to be most productive or least productive, thus improving ranch sustainability. This project reported in this fact sheet demonstrated that on each ranch there were both genetically inferior and superior livestock for the production traits analyzed. Participating ranchers are using the results to select replacements and are cautioned to avoid single trait selection. This project also created a baseline for genetic quality which individual ranches could compare with future DNA test results.

Corn Residue Stocking Rate Affects Cattle Performance But Not Subsequent Grain Yield, L. A. Stalker, H. Blanco-Canqui, Jennifer A. Gigax, A. L. Mcgee, T. M. Shaver, S. J. Van Donk
West Central Research and Extension Center, North Platte
This study investigated effects of stocking rate on cattle performance, quality and quantity of corn residue, and impact of residue removal on grain yield for 5 yr at the University of Nebraska – Lincoln West Central Water Resources Field Laboratory near Brule, NE. Four removal treatments—1) no removal (control), 2) grazing at 2.5 animal unit month (AUM)/ ha, 3) grazing at 5.0 AUM/ha, and 4) baling—were applied to a center pivot–irrigated corn field (53 ha). The field was divided into eight 6.6-ha paddocks to which replicated treatments were assigned. Samples of residue were collected in October and March (before and …
Management And Production Practices Of The Missouri Beef Cattle Industry, Jordan Lee Kinder
Management And Production Practices Of The Missouri Beef Cattle Industry, Jordan Lee Kinder
MSU Graduate Theses
A survey of beef cattle producers in Missouri was conducted to evaluate the management and production practices of the beef cattle industry. Production and demographic data from 112 (response rate of 5.9%) were analyzed to identify areas in need of future research and education. The web-based survey was conducted through Survey Monkey© and distributed by the Missouri Cattlemen's Association to a list of their members. Responding producers were located in 65 of the 114 counties in Missouri, with 63.3% located north of Interstate 44 and 36.7% south of Interstate 44. The majority (47.3%) of producers were between ages 31 and …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The objective was to retrospectively measure seasonal sunlight-associated variation in serum concentrations of 25-hydroxyvitamin D (25OHD) in beef cattle. The concentration of 25OHD was measured in crossbred animals born from March to May in 2011 and 2012. Vitamin D status 2 to 3 mo after birth (period 1) was only available for 2012 calves and was measured in June 2012. Period 1 animals had serum 25OHD concentrations of 26.3 +- 1.5 ng/mL. The 25OHD concentrations for late summer (period 2) were 46.6 +- 1.4 and 51.0 +- 1.5 ng/mL for 2011 and 2012, respectively. Serum concentration of 25OHD in early …

A 2-yr study utilizing 120 mature, crossbred (Angus × Herford) cows/year, evaluated the influence of cow BCS and dried distillers grains with solubles (DDGS) supplementation during late gestation on cow performance and productivity of subsequent offspring. Treatments were arranged as a 2 × 2 factorial in a randomized complete block design with 2 BCS and with or without DDGS supplementation. Cows were nutritionally managed to enter the last trimester of gestation with a BCS of approximately 4 (LBCS) or 6 (HBCS) and were thereafter managed in a single herd (initial BCS were 4.4 and 5.7 for LBCS and HBCS treatments, …

Two locations on a commercial ranch in the Nebraska Sandhills were used to determine the effects of maternal nutrition on male progeny. Crossbred, spring-calving, multiparous cows were managed in a year-round grazing system. Cows at one location (yr 1 = 754; yr 2 = 700) received the equivalent of 0.95 kg/d (DM; 31.6% CP; HN) of supplement, and cows at the second location (yr 1 = 673; yr 2 = 766) received 0.37 kg/d (DM; LN) of the same supplement delivered 3 times weekly while grazing winter range from December through February. After weaning, a random group (yr 1 = …

Effects Of Maternal Nutrition On Conceptus Growth And Offspring Performance: Implications For Beef Cattle Production, Richard N. Funston, David M. Larson, K. A. Vonnahme
West Central Research and Extension Center, North Platte
Developmental programming is the concept that a maternal stimulus or insult at a critical period in fetal development has long-term effects on the offspring. Historically, considerable effort has been made to understand how nutrition influences health and productivity during the postnatal period. Whereas maternal nutrition during pregnancy plays an essential role in proper fetal and placental development, less is known about how maternal nutrition affects the health and productivity of the offspring. Conceptus growth is sensitive to direct and indirect effects of maternal dietary intake. Even from the earliest stages of embryonic life, when nutrient requirements for conceptus growth are …
