Inflammation during early lactation is common in dairy cattle, and a high degree of inflammation during this time has recently been associated with both lower productivity and greater risk of disease during that lactation. Early lactation treatments with two non-steroidal anti-inflammatory drugs were compared with a placebo treatment to evaluate effects on whole-lactation productivity and retention in the herd. Both meloxicam and sodium salicylate increased whole-lactation milk and milk protein yields by 6 to 9%, despite being administered for only 1 or 3 days in early lactation, respectively. In addition, meloxicam treatment tended to decrease the risk of cows leaving …

Yeast Product Supplementation Influences Feeding Behavior And Measures Of Immune Function In Transition Dairy Cows (2014), Kai Yuan, Mary Beth Muckey, Luis Mendonca, Lindsey E. Hulbert
Kansas Agricultural Experiment Station Research Reports
Yeast supplementation has been shown to increase feed intake and production in some studies with early lactation dairy cows, but the mechanisms underlying this effect remain unknown. The objective of this study was to assess the effects of supplementing a yeast product derived from Saccharomyces cerevisiae on production, feeding behavior, and immune function in cows during the transition to lactation. When fed for 3 weeks before calving through 6 weeks after calving, supplementation altered feeding behavior as well as responsiveness to vaccination and gut immunoglobulin secretion. Results suggest that yeast products can modulate several aspects of immune function and promote …

Luteolysis And Pregnancy Outcomes After Change In Dose Delivery Of Prostaglandin F2Α In A 5-Day Timed Artificial Insemination Program In Dairy Cows (2014), Jeffrey S. Stevenson, Stephanie Leeann Pulley, Scott L. Hill
Kansas Agricultural Experiment Station Research Reports
Three experiments were conducted to determine if a larger dose of prostaglandin F2α (PG) administered on day 6 of a 5-day Ovsynch timed artificial insemination (AI) program would induce regression of the corpus luteum to facilitate AI and pregnancy outcomes similar to a traditional 5-day program with two doses of PG. When applying a 5-day program, cows that ovulate in response to the first GnRH injection have a new corpus luteum (CL) that is 2 days younger when PG is administered in a 5- versus 7-day program. To regress successfully the younger CL, a second injection of PG must be …

Reproductive success is relevant in beef cattle operations because income generated by the sale of calves is often a large portion of an operation's income. Selecting for fertility is difficult because it is influenced by a variety of factors. Temperament could be a factor affecting fertility. Physiological responses associated with temperament can influence the probability of cows becoming pregnant because stress hormones in the bloodstream can negatively affect the release of reproductive hormones. Methods have been developed to assess temperament in cattle. Exit velocity measures the time it takes for an animal to cover a predetermined distance after vacating a …

Kansas Agricultural Experiment Station Research Reports
Reproductive success is economically relevant in beef cattle operations because the number of calves born influences the value of calves sold at weaning. Improvements in reproductive performance can be up to four times more important than improvements in end-product traits in an operation selling calves at weaning. Selecting for fertility is difficult because it is influenced by a variety of factors. Temperament is one of the factors affecting fertility that requires further investigation. Researchers report that physiological responses associated with temperament can influence the probability of cows becoming pregnant. Stress hormones such as cortisol in the bloodstream can negatively affect …

Kansas Agricultural Experiment Station Research Reports
Optimizing cattle performance and maintaining pasture health are important considerations when striving to maximize profitability and sustainability on a Flint Hills pasture yearling grazing operation. The two growing seasons prior to initiation of this study were droughty and stressful to pastures. This situation provided an opportunity to evaluate the value of dried distillers grains with solubles (DDGS) as a self-fed supplement to ensure that nutritional resources were adequate for a 78-day grazing period. Grazing density was increased from 200 to either 225 or 250 lb of beef while simultaneously providing salt-limited DDGS supplements containing 10 and 16% salt, respectively.

Kansas Agricultural Experiment Station Research Reports
Omega-3 fatty acids are essential nutrients for humans, but American diets are often deficient in these important long-chain fats. Incorporating greater proportions of omega-3 fatty acids into beef offers a means of increasing daily consumption of essential fats, while also enhancing the perceived value of beef. In cattle, dietary polyunsaturated fats are extensively hydrogenated into saturated fats by microbes in the rumen. This effectively decreases the efficiency of transfer for fats from the animal's diet into edible beef tissues, because the bacteria convert more than 90% of the polyunsaturated fats into saturated fats before they are absorbed into the animal's …

Subprimals can be stored in a vacuum package for extended periods of time at low storage temperatures. The number of days that subprimals may be held before processing can be influenced by the distribution chain, accessibility, and subprimal price fluctuations. Extended vacuum storage before grinding could affect biochemical, oxidative, and microbial properties of these subprimals and influence sensory properties. Our objective was to determine the effects of two subprimal types (chuck roll and knuckle), two quality grades (Premium Choice and Select), and three vacuum-packaged storage aging times before processing (7, 21, and 42 days) on ground beef patty sensory properties.

Evaluating The Effectiveness Of Transport Media On Shiga Toxin-Producing E. Coli Serotypes (2014), Nicholas W. Baumann, A. West, Randall K. Phebus
Kansas Agricultural Experiment Station Research Reports
One of the key issues involved in accurately testing beef and the environment for the presence of specific bacteria, particularly pathogens such as Shiga toxin-producing Escherichia coli (STEC), is maintaining the viability of the microorganisms when transporting samples from the field to the laboratory. This process may take up to three days when considering collection, shipping and laboratory preparation times. Allowing the target bacteria to increase or decrease in numbers during transit is undesirable, so samples must be kept chilled and the media used for transport must offer a stable but non-nutritive environment. Three commonly used non-selective transport media were …

Kansas Agricultural Experiment Station Research Reports
Milking time may be a stressful event for lactating dairy cows during summer. Increases in body temperatures because of crowding in the milk parlor holding pen may contribute to increased heat stress. The objective of this extension project was to evaluate the effectiveness of heat stress abatement in milking facilities from two Kansas commercial dairies. Vaginal temperatures at milking were lower than vaginal temperatures before milking in one of the dairies. The lower vaginal temperatures at milking, however, were not observed in the other dairy at all milkings, likely because of differences in efficacy of heat abatement strategies. Milking facilities …

Kansas Agricultural Experiment Station Research Reports
Tenderness, juiciness, and flavor play important roles in a satisfactory beef eating experience. All three factors can be affected by management decisions made by producers during the production of beef. Beef producers currently use a multitude of production programs that utilize feed additives such as Rumensin or Tylan (Elanco Animal Health, Greenfield, IN), and growth promotants such as implants and Optaflexx (Elanco Animal Health). Rumensin and Tylan are fed in combination to improve feedlot performance, whereas growth promotants improve feed efficiency, average daily gain, hot carcass weight, and yield grades of carcasses. Although the use of feed additives and growth …

Kansas Agricultural Experiment Station Research Reports
Increased grazing pressure on sericea lespedeza by beef cattle, the most economically relevant herbivore in the region, may slow its spread and facilitate some measure of biological control. Unfortunately, mature plants contain high levels of condensed tannins that decrease protein digestion by beef cattle, and these compounds are potent deterrents to grazing. Supplementing corn steep liquor has been shown to alleviate the negative effects associated with ingestion of condensed tannins when beef cattle are fed prairie hay contaminated with sericea lespedeza. In addition, beef cows supplemented with corn steep liquor did not discriminate between sericea lespedeza-contaminated and sericea lespedeza-free prairie …

High-Dose Anabolic Implants Are Not All The Same For Growth And Carcass Traits Of Feedlot Steers: A Meta-Analysis (2014), Christopher D. Reinhardt
Kansas Agricultural Experiment Station Research Reports
The beneficial effects of anabolic implants with respect to feedlot performance and carcass weight are nearly unequivocal. Although individual prospective studies may have concluded that there are no significant differences between implant dosages, modern production economics demand that any differences, however small, must be gleaned if they are real. The objective of this study was to conduct a meta-analysis of existing data from peer-reviewed as well as industry sources to compare the effects of different doses of anabolic implants on feedlot performance and carcass traits of steers.
Udder Quality Is Moderately Heritable In Hereford Cattle (2014), Heather L. Bradford, Daniel W. Moser, Jennifer M. Bormann, Robert L. Weaber
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 …

Heifer Calving Rate Is Lowly Heritable In Hereford Cattle (2014), Heather L. Bradford, Daniel W. Moser, Jennifer M. Bormann, Robert L. Weaber
Kansas Agricultural Experiment Station Research Reports
Reproductive failure is consistently a top reason for culling beef cows from the herd. Culling young females is very costly to commercial producers because a young female hasn't generated enough income to pay for the cost of developing that female. One way to improve reproductive performance in the cowherd is through genetics. Although reproductive traits tend to be lowly heritable, genetic improvement can be made through selection. Beef producers traditionally have selected for increased scrotal circumference to improve female fertility. Scrotal circumference is an indicator trait and is positively correlated to female reproductive performance. Faster genetic improvement could be made …
