Kansas Agricultural Experiment Station Research Reports

The majority of cattle fed in commercial feedlots are processed and placed into pens without sorting into groups of uniform size and body condition. As a result of the variability in weight and condition, this management practice may lead to some cattle being fed beyond their optimal harvest point, whereas others are underconditioned and harvested prematurely, and thus fail to reach desired weight or quality grade necessary to attract available carcass premiums. Our objective was to determine if ultrasound technology could be utilized with lightweight calves as a means of predicting carcass fat thickness and yield grade outcomes. If successful, …

Automated Activity Monitoring Of Estrus And Time Of Ovulation (2013), Jeffrey S. Stevenson Jan 2013

Automated Activity Monitoring Of Estrus And Time Of Ovulation (2013), Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Detection of estrus can be facilitated by use of automated activity monitors that measure physical activity. Increased physical activity is largely correlated with estrus. Our objective was to determine when ovulation occurs relative to increased physical activity so we could recommend optimal timing of insemination to maximize conception rates in lactating dairy cows. Cows (n = 65) were fitted with pressure-sensitive rump-mounted transmitters (HeatWatch; HW) that are activated by a mounting herdmate to indicate standing estrus. The same cows also were fitted with neck-mounted activity monitors (Select Detect; SD). Additional cows (n = 68) were fitted with only the activity …

Commentary: Increasing Productivity, Meat Yield, And Beef Quality Through Genetic Selection, Management, And Technology (2013), Michael E. Dikeman Jan 2013

Commentary: Increasing Productivity, Meat Yield, And Beef Quality Through Genetic Selection, Management, And Technology (2013), Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

The primary purpose of producing beef cattle is to convert grass, forages, and various byproducts, plus human-edible protein and energy, into highly nutritious and tasty beef. To accomplish this, (1) cattle enterprises must be profitable; (2) carcasses should yield a high percentage of meat; (3) beef should be safe, affordable, attractive, nutritious, and highly palatable; and (4) both production and processing systems must be socially and environmentally responsible. The U.S. population has doubled since 1952, but the number of cows in the U.S. is the lowest since the 1950s. At the same time, a rather dramatic increase in beef production …

Exposure Of Prepubertal Beef Bulls To Cycling Females Affects Neither Age At Puberty Nor Ability To Pass An Initial Breeding Soundness Examination (2013), N. Miller, Ryan M. Breiner, Tom Taul, Sharon K. Tucker, Karol E. Fike Jan 2013

Exposure Of Prepubertal Beef Bulls To Cycling Females Affects Neither Age At Puberty Nor Ability To Pass An Initial Breeding Soundness Examination (2013), N. Miller, Ryan M. Breiner, Tom Taul, Sharon K. Tucker, Karol E. Fike

Kansas Agricultural Experiment Station Research Reports

Age at puberty is a crucial factor influencing a young bull's ability to pass a breeding soundness examination (BSE) at a year of age, and reducing that age may prove beneficial to beef producers. For beef females, exposure to mature bulls is known to hasten the onset of puberty and also can reduce the duration of postpartum anestrus. Relatively little research has evaluated the effects of female exposure on beef bull sexual development. Bulls are thought to use visualization rather than olfaction as their primary and preferred way to detect estrus in females. The purpose of this study was to …

Dosing With Lactipro Decreases Forage Intake And Manure Output (2013), K.A. Miller, C.L. Van Bibber-Krueger, C.C. Aperce, C.A. Alvarado, James S. Drouillard Jan 2013

Dosing With Lactipro Decreases Forage Intake And Manure Output (2013), K.A. Miller, C.L. Van Bibber-Krueger, C.C. Aperce, C.A. Alvarado, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

High-concentrate diets consisting of cereal grains and grain byproducts have high energy density compared with forage-based diets. To avoid digestive disorders, cattle must be adapted to concentrates, which often entails feeding a series of step-up diets that contain progressively less roughage over a 2- to 3-week period. This allows the microbial population to adapt to fermentation of the starches and sugars that are present in high-concentrate diets. If cattle are not properly adapted to concentrate-based diets, lactic acid, which is produced by opportunistic starch-fermenting bacteria like Streptococcus bovis, can accumulate, predisposing the animal to acidosis. Diets used during the adaptation …

Hydrated Lime Matrix Decreases Ruminal Biohydrogenation Of Flaxseed Fatty Acids (2013), C.A. Alvarado, C.C. Aperce, E. Van Cleef, K.A. Miller, C.L. Van Bibber-Krueger, F. Scarpino, D. Klamfoth, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Omega-3 fatty acids are essential nutrients for humans, but dietary intake of these nutrients by many Americans is inadequate due to low consumption of omega-3-rich foods such as fish, walnuts, and flaxseed. In contrast, per capita consumption of red meat is relatively high, but these products normally contain only small amounts of omega-3 fatty acids. Feeding cattle diets that contain omega-3 fatty acids has consistently increased the proportion of the desirable fats that accumulate in beef. Unfortunately, the proportion of dietary omega-3 fats that are deposited into beef tissues is relatively low, because microorganisms within the rumen biohydrogenate the unsaturated …

Insecticide Ear Tags Numerically Improve Grazing Cattle Performance (2013), S.E. Hill, Brandon E. Oleen, William R. Hollenbeck, Christopher I. Vahl, Dale A. Blasi Jan 2013

Insecticide Ear Tags Numerically Improve Grazing Cattle Performance (2013), S.E. Hill, Brandon E. Oleen, William R. Hollenbeck, Christopher I. Vahl, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Stocker cattle grazing pastures during the summer months face challenges due to horn flies, which can result in reduced weight gains and less efficient use of forages. One strategy for controlling horn flies is insecticide-impregnated ear tags. The use of pesticide ear tags may be an effective management practice to improve overall productivity during a grazing season. The objective of this study was to evaluate the efficacy of insecticide ear tags as a means of improving growth of stocker calves grazing native pastures in the Flint Hills region of Kansas.

Effects Of Corn Processing And Wet Corn Gluten Feed On Newly Received And Growing Cattle (2013), A.V. Siverson, Brandon E. Oleen, Evan C. Titgemeyer, Sean P. Montgomery, Dale A. Blasi Jan 2013

Effects Of Corn Processing And Wet Corn Gluten Feed On Newly Received And Growing Cattle (2013), A.V. Siverson, Brandon E. Oleen, Evan C. Titgemeyer, Sean P. Montgomery, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Newly arrived feedlot cattle present numerous challenges and are often considered to be the most difficult type of fed cattle to handle. Receiving cattle typically are highly stressed and have had feed withheld for a significant amount of time. Formulating rations that are cost-effective and nutrient-dense is essential to accommodating lowered intake. The objective of this experiment was to evaluate effects of corn processing (whole shelled or dry-rolled), wet corn gluten feed (WCGF) inclusion, and their interaction on cattle performance.

Orally Dosing Steers With Lactipro (Megasphaera Elsdenii) Decreases The Quantity Of Roughages Fed During Finishing (2013), K.A. Miller, C.L. Van Bibber-Krueger, James S. Drouillard Jan 2013

Orally Dosing Steers With Lactipro (Megasphaera Elsdenii) Decreases The Quantity Of Roughages Fed During Finishing (2013), K.A. Miller, C.L. Van Bibber-Krueger, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

The cost of roughages is relatively high in comparison to their contribution of nutrients to feedlot diets. Widespread drought has affected roughage supplies in the cattle-feeding regions of the United States, further increasing the cost of roughages for feedlots. Despite their relatively high cost, roughages are incorporated into finishing diets to maintain rumen function and to manage ruminal acidosis. The greatest proportion of roughage is utilized early in the feeding period when cattle are being transitioned from forage-based diets to concentrate-based diets, allowing ruminal microbes to adapt gradually to higher levels of starch and sugars. If cattle are not properly …

Altering Dietary Calcium Does Not Influence Tenderness In Cattle Fed Zilmax (2013), C.L. Van Bibber-Krueger, K.A. Miller, James S. Drouillard Jan 2013

Altering Dietary Calcium Does Not Influence Tenderness In Cattle Fed Zilmax (2013), C.L. Van Bibber-Krueger, K.A. Miller, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Tenderness is a key contributor to the sensory attributes of beef, and production practices that decrease tenderness are generally viewed as unfavorable. Zilmax (Merck Animal Health, Summit, NJ) is a potent beta-adrenergic agonist that results in dramatic improvements in carcass weight when fed to cattle, normally for a period of 20 days prior to harvest. Zilmax increases muscle mass at the expense of body fat, and these changes can have favorable effects on retail yield and overall value of beef carcasses. One of the unfavorable side effects of Zilmax is a decrease in meat tenderness. Aging of beef is one …

Evidence Of Estrus Before Cidr Insertion Does Not Influence Pregnancy Rate To Fixed-Timed Artificial Insemination In Beef Heifers, Sandra K. Johnson, M.A. Ward, O.L. Swanson, G.A. Perry Jan 2013

Evidence Of Estrus Before Cidr Insertion Does Not Influence Pregnancy Rate To Fixed-Timed Artificial Insemination In Beef Heifers, Sandra K. Johnson, M.A. Ward, O.L. Swanson, G.A. Perry

Kansas Agricultural Experiment Station Research Reports

Protocols used for fixed-timed artificial insemination strive to synchronize growth of follicular waves and commonly do so by administration of gonadotropin-releasing hormone (GnRH) at the beginning of the treatment. The stage of the cycle at the time of GnRH injection influences the proportion of animals that respond, and cows respond more consistently than heifers. Variability in response to GnRH has been offered as an explanation for why why short-term fixed-timed insemination protocols tend to be less effective in heifers than cows. The dairy industry has used prostaglandin (PG) to "pre-synchronize" cow ovulation before a protocol to improve the proportion of …

Presynchronizing Pgf2Α And Gnrh Injections Before Timed Artificial Insemination Co-Synch + Cidr Program (2013), Scott L. Hill, Stephanie Leeann Pulley, K. C. Olson, John R. Jaeger, Ryan M. Breiner, G.C. Lamb, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Fixed-time artificial insemination is an effective management tool that reduces the labor associated with more conventional artificial insemination programs requiring detection of estrus. The 7-day CO-Synch + controlled internal drug release (CIDR) insert protocol has been shown to effectively initiate estrus and ovulation in cycling and non-cycling suckled beef cows, producing pregnancy rates at or greater than 50% in beef cows. The gonadotropin-releasing hormone (GnRH) injection that begins the CO-Synch + CIDR program initiates ovulation in a large proportion of cows, particularly anestrous cows. The CIDR, which releases progesterone intravaginally, prevents short estrous cycles that usually follow the first postpartum …

Efficiency Of Early Weaned Beef Calves Is Not Improved By Restricting Feed Intake During 84-Day Growing Phase (2013), E.A. Bailey, G.W. Preedy, L.A. Pacheco, John R. Jaeger, Justin W. Waggoner, K. C. Olson Jan 2013

Efficiency Of Early Weaned Beef Calves Is Not Improved By Restricting Feed Intake During 84-Day Growing Phase (2013), E.A. Bailey, G.W. Preedy, L.A. Pacheco, John R. Jaeger, Justin W. Waggoner, K. C. Olson

Kansas Agricultural Experiment Station Research Reports

Early weaning can be used by cow-calf producers to reduce stocking rates by 20% to 30% during drought. Ranchers may be reluctant to wean early because of reduced calf weights and reduced revenue compared with weaning calves at conventional ages. To avoid revenue shortfalls, calves can be retained and grown before selling; however, grain prices are currently at unprecedented levels. Feeding grain-based diets to calves less than 125 days of age has been associated with excessive fat accumulation early in the feeding period and decreased carcass weights. Conversely, several researchers have noted marked improvements in feed efficiency when grain-based finishing …

Kansas Agricultural Experiment Station Research Reports

Crude glycerin is the principal byproduct of biodiesel production. The raw feedstocks, animal fats and vegetable oils, yield approximately 90 lb of biodiesel and 10 lb of crude glycerin for each 100 lb of input. When ingested by cattle, glycerin has two major fates: (1) direct absorption by the rumen epithelium, and (2) fermentation by microorganisms within the rumen to generate volatile fatty acid, mainly propionate. Using glycerin in feedlot cattle diets has become common, particularly as a component of liquid feed supplements. We have evaluated the use of crude glycerin in cattle diets in previous studies and generally have …
