Docility And Heifer Pregnancy Estimates In Angus Heifers (2014), Kari L. White, Jennifer M. Bormann, Daniel W. Moser, Robert L. Weaber

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

Cattle producers historically have selected for docile temperaments simply for management convenience because calmer animals are conducive to safe environments for their peers as well as their handlers. As many producers would acknowledge, however, there seems to be a relationship between temperament and cattle health, and calmer cattle tend to frequent the working chute for treatment of disease less often. Positive correlations have been found in cattle between temperament traits (chute scores, pen scores, and chute exit velocities) and cortisol concentration in the blood, suggesting that more excitable cattle are easily stressed (Curley et al., 2006; Cooke et al., 2009). …

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 …

Effects Of Corn Steep Liquor Supplementation On Performance And Herbivory Patterns Of Beef Cows Grazing Native Range Infested With Sericea Lespedeza (Lespedeza Cuneata) (2014), Garrett W. Preedy, K. C. Olson, Walter H. Fick, Leigh W. Murray Jan 2014

Effects Of Corn Steep Liquor Supplementation On Performance And Herbivory Patterns Of Beef Cows Grazing Native Range Infested With Sericea Lespedeza (Lespedeza Cuneata) (2014), Garrett W. Preedy, K. C. Olson, Walter H. Fick, Leigh W. Murray

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 …

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. …

Utilization Of Omega-3 Fatty Acids Is Improved By Embedding Flaxseed In A Matrix Of Dolomitic Lime Hydrate (2014), Christian A. Alvarado-Gilis, Cadra L. Van Bibber-Krueger, K. A. Miller, E. San Vito, G. Feltrin, D. Klamfoth, James S. Drouillard

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 …

Encapsulation Of Flaxseed In A Dolomitic Lime Matrix: Effects On Feedlot Performance And Carcass Characteristics Of Steers Vs. Heifers (2014), G. Feltrin, Christian A. Alvarado-Gilis, Cadra L. Van Bibber-Krueger, D. Klamfoth, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

We have investigated the potential for using hydrated lime to form protective matrices with oil-rich feeds, such as flaxseed, to increase the incorporation of omega-3 fatty acids into meat. Dolomitic lime is mixed with ground flaxseed, water is added, the mixture is blended in a high-speed turbulizer, and the resulting material is then dried to form a granular matrix. During the manufacturing process, a portion of the hydrated lime becomes recarbonated. This recarbonated matrix is ruminally stable, which prevents rumen microbes from converting polyunsaturated oils to saturated fats. Additional recarbonation occurs in the rumen due to exposure to high concentrations …
