Introduction
Grasslands in the Northern Plains provide the primary forage source for ruminants throughout much of the year (Schauer et al., 2004). Supplementation practices are often necessary to maintain production and offset forage nutritive decline throughout the grazing season (Schauer et al., 2004; Cline et al., 2009). Typically, to maintain a targeted production level, energy and protein supplementations are used for grazing livestock (Caton and Dhuyvetter, 1997). For developing heifers consuming low-quality forages, inclusion of energy ingredients into supplements may be beneficial for growth and reproductive performance (Schillo et al., 1992; Ciccioli et al., 2005; Cappellozza et al., 2014). In …

Use Of Distiller Grains In Alternative Beef Heifer Systems, Jared M. Mracek
Department of Animal Science: Dissertations, Theses, and Student Research
Every year, producers select replacement heifers with the intention that these heifers are the future of their cow herd. Producers normally select replacement heifers at weaning based on weight and structure. When selecting heifers at weaning, producers risk not selecting heifers that would be productive cows based on their criteria. By delaying the selection of replacements, it will allow producers to increase the opportunity to thoroughly evaluate replacement prospects. The corn dry-milling industry produces byproducts that can be economical supplements to growing cattle on forage. An experiment evaluated an alternative heifer system utilizing distiller grains as an energy source to …
Replacement Alternatives For Beef Cow Herds: An Analysis Of Retaining Non-Pregnant Cows, Trenton T. Bohling
Replacement Alternatives For Beef Cow Herds: An Analysis Of Retaining Non-Pregnant Cows, Trenton T. Bohling
Department of Agricultural Economics: Dissertations, Theses, and Student Research
A non-pregnant cow is a liability to a producer. Over the last four years, cow-calf producers have had an increased number of non-pregnant cows due to factors like environmental conditions and diseases like trichomoniasis. While most research has indicated that culling a non-pregnant female and replacing the cow with retained heifers, purchased heifers, or purchased cows are the only economic alternatives, recent trends in the cattle market have suggested that keeping a non-pregnant cow may also be an alternative.
Annual beef cow budgets were created based on typical Nebraska Sandhills conditions. Revenues and costs in these budgets vary according to …

G05-1583 How To Body Condition Score Dairy Animals, Jeffrey F. Keown
G05-1583 How To Body Condition Score Dairy Animals, Jeffrey F. Keown
University of Nebraska-Lincoln Extension: Historical Materials
Routinely scoring the body condition of dairy animals can help detect potential problems that might cause a decrease in milk production.
As the production level of a herd increases, body condition scoring becomes more important. A routine program for body condition scoring can help detect potential health problems before they significantly reduce milk production. A herd of cattle in good body condition will produce more, and will be less susceptible to metabolic disorders, disease, mastitis and reproductive problems. Underconditioned cows are subject to health problems, and overconditioned cows are subject to calving difficulties, fatty liver syndrome and possible death.

Department of Animal Science: Faculty Publications
Metabolizable protein (MP) requirements of spring calving heifers increase over the winter due to advancing gestation. The MP content of grazed winter forage is low, which may result in an MP deficiency. The objective was to compare the response of supplementing pregnant yearling heifers to meet MP requirements versus conventional CP supplementation. In 1997–98 and in 1998–99, pregnant, March-calving heifers (2,120 animals; 358 kg) at two locations of a commercial ranch in the Nebraska Sandhills, were used following breeding through calving as 2-yr-olds (cows). Heifers were randomly allotted to one of two supplementation treatments (about 265 heifers/treatment) each year at …

Assisting With Calving, Clell Bagley
Assisting With Calving, Clell Bagley
All Current Publications
Calving season is a busy time of year for cattlemen and it is a critical step toward a productive year. The first rule is frequent observation of those cows due to calve, especially the first calf heifers. This is usually a very busy time of year and some extra help during this season will more than pay for the cost through extra calves saved. Even wives and older children can help a solo producer get some needed sleep. If, they have been taught how to observe, they can tell when a calving cow needs help and if there’s a need …

G95-1262 Feeding The Beef Cow Herd--Part Ii Managing The Feeding Program, Richard J. Rasby, Ivan G. Rush, Don C. Adams
University of Nebraska-Lincoln Extension: Historical Materials
Feed costs are the cow/calf producer's greatest expense in producing a weaned calf. To remain competitive, cow/calf operators must use economical feeding programs. It is important to match the available feed resources with the nutrient requirements of the first-calf-heifer and cow. Both over- and underfeeding the cow herd can lead to high production costs.
Nutrient requirements for heifers calving as 2-year-olds and cows calving as 3-year-olds and older are shown in Table I. Beef cows are seldom fed complete rations where ingredients are weighed daily. Generally, most of a cow's ration is forages such as: 1) summer and winter range, …
G95-1235 Growth Implants On Beef Heifer Reproduction, Gene H. Deutscher
G95-1235 Growth Implants On Beef Heifer Reproduction, Gene H. Deutscher
University of Nebraska-Lincoln Extension: Historical Materials
This guide discusses the benefits and concerns in the use of growth implants with beef heifers. Growth promoting implants are used extensively in beef cattle finishing programs and in suckling and growing steer programs. Implants are one of the most economical means of improving performance. However, producers are concerned with implanting suckling and growing heifers because of the possible negative effects on subsequent reproduction of heifers selected as replacements. Replacement heifers need to grow rapidly, reach puberty early, conceive early, and increase in skeletal structure to reduce calving difficulty. If implants could be used to increase growth and skeletal structure …
