Udder Quality Is Moderately Heritable In Hereford Cattle (2014), Heather L. Bradford, Daniel W. Moser, Jennifer M. Bormann, Robert L. Weaber Jan 2014

Udder Quality Is Moderately Heritable In Hereford Cattle (2014), Heather L. Bradford, Daniel W. Moser, Jennifer M. Bormann, Robert L. Weaber

Kansas Agricultural Experiment Station Research Reports

Udder quality is an important factor related to cow longevity and calf performance. Cows with tighter udder suspension and smaller teats tend to have greater longevity. When cows stay in the herd longer, fewer replacement heifers need to be developed to maintain herd size. Pendulous, poorly suspended udders and large teats are difficult for newborn calves to nurse, and additional labor might be required to assist those calves. Cows with poor udder quality can have increased calf mortality because the calf struggles to nurse and consumes colostrum later. Because many beef producers sell calves by the pound at weaning, poor …

Administration Of Prostaglandin To Beef Heifers At Time Of Artificial Insemination (2014), Sandra K. Johnson, John R. Jaeger Jan 2014

Administration Of Prostaglandin To Beef Heifers At Time Of Artificial Insemination (2014), Sandra K. Johnson, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Transportation of sperm is a critical component of reproductive success. Another factor in reproductive success are the contractions of the uterine myometrium, which influence the number of sperm that reach the oviduct. prostaglandin F2α(PG) is present in bull semen and has a variety of functions in reproduction, including stimulating myometrial contractions. Evidence of improved fertility after administration of PG at breeding has been shown in the rabbit, sow, and cow. An injection of PG at the time of insemination improved conception rates in heifers inseminated with semen with only 30% motility. The objective of the study was to determine if …

Botanical Composition Of Beef Cow Diets Shifts When Native Range Infested With Sericea Lespedeza (Lespedeza Cuneata) Is Supplemented With Corn Steep Liquor (2014), Garrett W. Preedy, K. C. Olson, Leigh W. Murray, Walter H. Fick Jan 2014

Botanical Composition Of Beef Cow Diets Shifts When Native Range Infested With Sericea Lespedeza (Lespedeza Cuneata) Is Supplemented With Corn Steep Liquor (2014), Garrett W. Preedy, K. C. Olson, Leigh W. Murray, Walter H. Fick

Kansas Agricultural Experiment Station Research Reports

Corn steep liquor supplementation indicated that a higher percentage of sericea lespedeza plants were defoliated in pastures grazed by corn steep liquor-supplemented cows than in pastures grazed by unsupplemented cows; however, it was unknown if defoliation was related directly to grazing activity of cows. Therefore, our objective was to evaluate the effects of supplemental corn steep liquor on botanical composition of the diets of beef cows grazing native tallgrass rangeland infested with sericea lespedeza in the Kansas Flint Hills.

Combining Ruminally Protected Choline And Flaxseed In Cattle Diets To Increase The Assimilation Of Omega-3 Fatty Acids From The Diet (2014), Caleb P. Weiss, Cadra L. Van Bibber-Krueger, K. A. Miller, Christian A. Alvarado-Gilis, James S. Drouillard Jan 2014

Combining Ruminally Protected Choline And Flaxseed In Cattle Diets To Increase The Assimilation Of Omega-3 Fatty Acids From The Diet (2014), Caleb P. Weiss, Cadra L. Van Bibber-Krueger, K. A. Miller, Christian A. Alvarado-Gilis, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Omega-3 fatty acids are an essential part of a healthy human diet. If consumed regularly, these fatty acids attenuate inflammation and lower risk of inflammatory diseases, such as heart disease and rheumatoid arthritis. The human body cannot synthesize adequate amounts of omega-3 fatty acids; they must be obtained by consuming foods that are rich in omega-3s. Omega-3 fatty acids can be found in foods like fish, some oilseeds, and some nut oils. Overall consumption of these foods is relatively low compared with the consumption of red meat such as beef, which typically contains relatively small amounts of omega-3 fatty acids. …

Wheat Straw Improved By Half-Rate Application Of Anhydrous Ammonia (2014), Justin W. Waggoner, R. Reid, Brandon E. Oleen, William R. Hollenbeck, Jody G. Holthaus, A. Sexten, J. Petersilie, Robert L. Weaber, S. Johnson, Dale A. Blasi Jan 2014

Kansas Agricultural Experiment Station Research Reports

Many tons of crop residues and other low-quality forages are produced in Kansas each year. Use of these forages often is limited by their low nutrient content and poor digestibility. The process of applying anhydrous ammonia to low-quality forages enhances their feeding value by increasing crude protein content and dry matter digestibility. In the summer of 2012, the persistence of drought conditions throughout Kansas reduced forage supplies and resulted in a dramatic increase in forage prices. In an effort to aid livestock producers, the K-State Beef Extension Specialist Team, in conjunction with the Livestock Production Program Focus Team, conducted wheat …

Effects Of Media Type On Shiga Toxigenic E. Coli Growth Patterns (2014), Nicholas W. Baumann, Nicholas J. Sevart, Minto Michael, Donka T. Milke, G. Lewis, R. Moxley, Randall K. Phebus Jan 2014

Kansas Agricultural Experiment Station Research Reports

Escherichia coli O157:H7 was declared to be an adulterant in raw ground beef in 1994 by the United States Department of Agriculture Food Safety and Inspection Service following a large and deadly foodborne disease outbreak in the Pacific Northwest involving undercooked hamburgers sold at Jack-in-the-Box restaurants. Due to their recognition as significant human foodborne pathogens, six additional strains (serotypes) of Shiga toxin-producing E. coli (STEC) were also deemed to be adulterants in raw beef products in 2012. The beef processing industry has worked diligently since the mid-1990s to control the presence of E. coli O157:H7 in finished raw products through …

Evaluation Of Ammoniated Wheat Straw In Receiving And Growing Diets, E. R. Schlegel, S. P. Montgomery, J. W. Waggoner, C. I. Vahl, W. R. Hollenbeck, B. E. Oleen, D. A. Blasi Jan 2014

Kansas Agricultural Experiment Station Research Reports

Drought conditions in the past have created a shortage of prairie hay and other grass hays that are used as roughage sources for growing beef diets. Ammoniated wheat straw historically has been available for purchase at a lower than prairie hay. Although some research has been conducted using ammoniated wheat straw as a feedstuff for mature cows, little information is available on the use and outcome its inclusion in beef cattle receiving and growing diets. Our objective was to compare the performance outcomes of newly arrived and growing calves fed total mixed rations containing either ammoniated wheat straw, wheat straw, …
