Incidence Of Pregnancy In Feedlot Heifers At Slaughter, S.B. Laudert Jan 1988

Incidence Of Pregnancy In Feedlot Heifers At Slaughter, S.B. Laudert

Kansas Agricultural Experiment Station Research Reports

Nearly 83,000 heifers were observed at slaughter during 1986 and 1987 to determine their reproductive status. Slightly less than 4 percent were found to be pregnant. Highest incidences of pregnancy were found during the winter months of November through March. Lowest incidences were found during August, September. and October.


Animal Drugs And The Milk Supply, R.W. Wilson Jan 1988

Animal Drugs And The Milk Supply, R.W. Wilson

Kansas Agricultural Experiment Station Research Reports

The makers of the laws, rules, and regulations governing the production and processing of milk have recognized that milk is the primary diet of the very young and old. This fact mandates that it should be produced and processed in a manner to protect and maintain it in a pure, safe, and unadulterated condition. To determine adulteration of any milk product, one must first understand the legal definition of that product. In general, milk is defined as "the lacteal secretion of healthy cows that is practically free from colostrum." Anything that alters the product from the intent of this definition ...


Milking Management Clinics, James R. Dunham, Edward P. Call Jan 1988

Milking Management Clinics, James R. Dunham, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

Thirty Milking Management Clinics have been conducted at various on-farm locations. The clinics have demonstrated that good milking techniques can result in an additional 1891 lb milk yield/cow in a 10-mo lactation and an increased milk flow rate of 0.9 lb/min. Additional demonstrations include: I) teat dipping techniques, 2) proper sanitation programs, 3) antibiotic sensitivity culturing, 4) residue avoidance programs, 5) dry cow treatment techniques, and 6) milking equipment evaluation.; Dairy Day, 1988, Kansas State University, Manhattan, KS, 1988;

Bovine Recombinant Interleukin-2 Enhances Resistance To Bovine Herpesvirus-1: Dose Response Trial, P.G. Reddy, Frank Blecha, J.L. Morrill, H.C. Minocha

Kansas Agricultural Experiment Station Research Reports

Twenty-five calves were allotted to five groups: controls that did not receive bovine recombinant interleukin-2 (rIL-2) and four groups that received 5 daily injections of rIL-2 at 11.4, 1.1,0.11, or 0.0 II µg/lb/day. On day 0 of the experiment, all calves received bovine herpesvirus-I (BHV-1) vaccine and the first of the 5 daily injections of bovine rIL-2. All calves were infected with BHV-Ion day 21 of the experiment. Calves treated with 11.4 µg /Ib/day had elevated rectal temperatures and mild diarrhea during administration of rIL2. All other calves were normal. Compared ...


Effect Of Route Of Administration Of Lasalocid On Response Of Young Dairy Calves, S.D. Pruitt, J.L. Morrill, Tiruvoor G. Nagaraja, N.V. Anderson Jan 1988

Effect Of Route Of Administration Of Lasalocid On Response Of Young Dairy Calves, S.D. Pruitt, J.L. Morrill, Tiruvoor G. Nagaraja, N.V. Anderson

Kansas Agricultural Experiment Station Research Reports

Forty newborn bull calves were assigned to one of four feeding groups. The feeds either contained lasalocid in milk (M), prestarter (PS), and starter (S); lasalocid in PS and S; lasalocid in S only; or no lasalocid. Calves were fed M at 8% of birth weight (bw) daily and offered PS to a maximum of 0.5 lb daily. When 0.5 lb of PS was consumed in one day the calves were fed M at 4% of bw daily. They were weaned when they consumed dry feed at the rate of 1.3% of bw. Daily feed intake and ...


The Evaluation Of Rapid Methods For Monitoring Free Fatty Acid Levels In Cheese, W.G. Ikins, H.S. Kwak, G.S. Zink, I.J. Jeon Jan 1988

The Evaluation Of Rapid Methods For Monitoring Free Fatty Acid Levels In Cheese, W.G. Ikins, H.S. Kwak, G.S. Zink, I.J. Jeon

Kansas Agricultural Experiment Station Research Reports

The amount of free fatty acids present in cheese is important to dairy processors because these compounds make a significant contribution to the overall flavor. In this study, the results obtained using three relatively rapid methods of determining free fatty acids concentrations in cheese were compared to those acquired by using a more laborious but accurate gas chromatographic technique. One method, the Extraction-Titration Method, was found to be superior to the others because of its simplicity and reliability. In addition, the values obtained by this method were found to closely correlate with short chain fatty acid concentrations of cheese as ...


Small Intestinal Starch, Dextrin, And Glucose Digestion In Steers, K.K. Kreikmeier, D.L. Harmon, T.B. Avery, Robert T. Brandt Jr. Jan 1988

Small Intestinal Starch, Dextrin, And Glucose Digestion In Steers, K.K. Kreikmeier, D.L. Harmon, T.B. Avery, Robert T. Brandt Jr.

Kansas Agricultural Experiment Station Research Reports

Three Holstein steers (930 lb) were surgically fitted with abomasal and ileal cannulae, portal and mesenteric venous catheters, and an elevated carotid artery and used to study small intestinal starch digestion. Water, corn starch (66 g/hr), corn dextrin (66 g/hr), or glucose (66 g/hr) were continuously infused into the abomasum. Small intestinal disappearance of corn dextrin (57 g/hr) and glucose (57 g/hr) were higher (P<.05) than that of starch (48 g/hr). The percentage of carbohydrate disappearance accounted for as net portal glucose flux was 52, 54, and 72% for corn starch, corn dextrin, and glucose, respectively. Small intestinal starch utilization in the bovine may be limited by starch granular characteristics, enzyme activity, and glucose transport across the small intestine.; Dairy Day, 1988, Kansas State University, Manhattan, KS, 1988;


Effects Of Production On Reproductive Traits In Kansas Holstein Herds, Edward P. Call Jan 1988

Effects Of Production On Reproductive Traits In Kansas Holstein Herds, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

The analysis of dairy herds to evaluate the reported negative effect of production on reproduction failed to identify a real relationship. Higher-producing herds excel in all areas of reproductive performance, except conception rate. Of greatest importance is the annual reproductive loss that is affected by the reproductive traits measured. As production per cow increased, the yearly dollar loss per cow declined from a high of $163 to $73 yearly in the group averaging 20,118 lb milk.; Dairy Day, 1988, Kansas State University, Manhattan, KS, 1988;


Cause And Control Of Hydrolytic Rancidity In Raw Milk, I.J. Jeon Jan 1988

Cause And Control Of Hydrolytic Rancidity In Raw Milk, I.J. Jeon

Kansas Agricultural Experiment Station Research Reports

One of the common and important off-flavors in milk is hydrolytic rancidity or lipolyzed flavor. The rancidity results from hydrolytic cleavage of fatty acids from milk fat by the enzyme lipase and their release as free acids. The release of these acids in milk, even in very small amounts, imparts a bitter taste and a sharp, unpleasant aroma. The off-flavor is often described as "goaty", "butyric", "soapy", and "bitter" The term "bitter", however, is ambiguous because bitter flavors can occur from the result of protein breakdowns. Nevertheless, both farm and dairy plant problems may lead to its development. Once an ...


Evaluation Of Mga And Prostaglandin As An Estrous Synchronization Procedure Under Field Conditions, P.L. Houghton, L.R. Corah, T.B. Goehring Jan 1988

Evaluation Of Mga And Prostaglandin As An Estrous Synchronization Procedure Under Field Conditions, P.L. Houghton, L.R. Corah, T.B. Goehring

Kansas Agricultural Experiment Station Research Reports

When fed MGA (0.5 mg.hd/day) for 14 days, followed by a prostaglandin injection 17 days later, a total of 736 out of 1112 heifers at 11 locations expressed signs of estrus within 5 days following the PG injection for a 66.2% response to synchronization. Response rates between locations ranged from 33 to 95% (P<.05). In a comparison of prostaglandin forms at 5 locations, using 789 heifers, response to synchronization was similar (P=.66) between Lutalyse® (62.7% response) and Bovilene® (59.6% response). First-service conception rate was compared in 411 heifers at two locations and was higher for Lutalyse (68.996) than Bovilene (59.996) (P<.08). First-service conception rate varied by technician (P<.05) and ranged from 48.7 to 83.6%.


Effect Of Hay Quality And Breed On The Onset Of Puberty And Subsequent Reproductive Performance In Beef Heifers, R.C. Perry, L.R. Corah, R.C. Cochran, J.R. Brethour Jan 1988

Effect Of Hay Quality And Breed On The Onset Of Puberty And Subsequent Reproductive Performance In Beef Heifers, R.C. Perry, L.R. Corah, R.C. Cochran, J.R. Brethour

Kansas Agricultural Experiment Station Research Reports

The effect of hay quality on the onset of puberty and subsequent reproductive performance was evaluated in 51 3/4 Hereford x 1/4 Angus (HA) heifers and 47 3/4 Hereford x 1/4 Brahman (HB) heifers. Two qualities of alfalfa hay were fed ad libitum. along with an average of 3.1 lbs/hd/day of ground sorghum grain. HB heifers were heavier and carrying more backfat and body condition (P<.05) at the start of the experiment and they maintained their weight advantage through out the experiment. A higher (P<.05) percent of the UB heifers reached puberty by 14 and 15 months of age and became pregnant during a 45 day artificial insemination breeding period. HA heifers reached puberty at a lighter (P<.05) average weight. Heifers fed high quality alfalfa hay were heavier (P<.05) by the start of the breeding season and were carrying more (P<.05) backfat and body condition. A higher percent (P=.08) of the heifers receiving higher quality hay reached puberty by 16 months of age and a higher (P=.10) percent became pregnant during the breeding period. Heifers inseminated at their pubertal estrus had lower (P=.04) first service conception rates than heifers inseminated at their second or later estruses (52% vs. 88%).


Influence Of Limited-Creep Feeding On Pre And Postweaning Performance Of Spring Born Calves, P. Houghton, F. Brazle, Gerry L. Kuhl, B. Schalles, K. Zoellner Jan 1988

Influence Of Limited-Creep Feeding On Pre And Postweaning Performance Of Spring Born Calves, P. Houghton, F. Brazle, Gerry L. Kuhl, B. Schalles, K. Zoellner

Kansas Agricultural Experiment Station Research Reports

Two limited-creep feeding trials were conducted in Northwest and Southeast Kansas using spring-born, suckling calves to evaluate the effect of available forage supply on creep-fed calf performance. Energy vs. protein creep feeds were compared at each location. Creep feed intake was limited with salt to achieve an average daily intake of about 1.5 lb per head. Calves consuming the limited energy and protein creep feeds gained from 0.1 to 0.6 lb more per head daily preweaning, and required 2.3 to 7.6 lb of creep per lb of extra weaning weight. Postweaning gains of the noncreep-fed ...


Morning Versus Evening Supplementation For Heifers Grazing Winter Range, E. Vanzant, B. Cochran, L. Corah, K. Zoellner Jan 1988

Morning Versus Evening Supplementation For Heifers Grazing Winter Range, E. Vanzant, B. Cochran, L. Corah, K. Zoellner

Kansas Agricultural Experiment Station Research Reports

Supplementing developing heifers in the morning was compared with supplementation at sundown. No difference was evident among treatments in average daily gain, distance traveled, or time spent grazing.


Influence Of Supplemental Protein Versus Energy Level On Intake, Fill, Passage, Digestibility, And Fermentation Characteristics Of Beef Steers Consuming Dormant Bluestem Range Forage, T. Delcurto, B. Cochran, T. Avery, A. Beharka Jan 1988

Influence Of Supplemental Protein Versus Energy Level On Intake, Fill, Passage, Digestibility, And Fermentation Characteristics Of Beef Steers Consuming Dormant Bluestem Range Forage, T. Delcurto, B. Cochran, T. Avery, A. Beharka

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to evaluate effects of protein versus energy level in milo/soybean meal supplements on intake and utilization of dormant, bluestem forage. Forage dry matter intake and utilization of dormant bluestem forage appears to increase at higher levels of supplemental protein. Increased supplemental energy may be associated with depressed intake and utilization, particularly when supplements are low in protein.


Stocking Rate Effects On Intensive-Early Stocked Bluestem Range, R. Cochran, E.F. Smith, Clenton E. Owensby Jan 1988

Stocking Rate Effects On Intensive-Early Stocked Bluestem Range, R. Cochran, E.F. Smith, Clenton E. Owensby

Kansas Agricultural Experiment Station Research Reports

Based on a six-year study, stocking at 2.5x and 3.0x normal season-long rates for the first half of the growing season with no grazing during the latter half results in individual steer gains that are equal to those under the 2.0x rate. The gain per acre was greatly increased at the higher stocking rates. Grass remaining in early October was 20 percent lower on pastures stocked at the 2.5x and 3.0x rates than at the 2.0x rate. However, there was no trend toward further reductions over the study period. Botanical composition did not change ...


Effect Of Medicated Mineral Mixtures And A Pinkeye Vaccine On The Gain And Health Of Steers Grazing Native Grass Pastures, F. Brazle Jan 1988

Effect Of Medicated Mineral Mixtures And A Pinkeye Vaccine On The Gain And Health Of Steers Grazing Native Grass Pastures, F. Brazle

Kansas Agricultural Experiment Station Research Reports

Feeding supplements containing an antibiotic or ionophore improved stocker gains by .06 to .26 lb per head daily. A combination of Bovatec and Aureomycin in the mineral mixture improved (P<.08) steer gains over feeding Aureomycin alone. Mineral intake was higher than expected for the steers grazing burned, double-stocked) native grass pastures in 1987. Vaccinating steers with Piliguard at turn-out had no effect on pinkeye incidence and reduced stocker gains slightly.


The Effect Of Physical Characteristics On The Price Of Stocker And Feeder Cattle, F. Brazle, J. Mintert, Ted C. Schroeder, O. Grunewald Jan 1988

The Effect Of Physical Characteristics On The Price Of Stocker And Feeder Cattle, F. Brazle, J. Mintert, Ted C. Schroeder, O. Grunewald

Kansas Agricultural Experiment Station Research Reports

A survey of feeder cattle sales was conducted at seven Kansas cattle auctions during 1986 and 1987. A wide variety of physical characteristics was found to influence feeder cattle prices. The price impact resulting from changes in fill and condition varied seasonally. Although calves showing any signs of health problems received severe price discounts, the presence of other undesirable characteristics also resulted in discounts, but to lesser degrees.


Farm, Wholesale, And Retail Beef Price Relationship, Ted C. Schroeder Jan 1988

Farm, Wholesale, And Retail Beef Price Relationship, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Analysis of weekly retail, wholesale, and farm beef price data indicated that a time lag exists between price changes at the various market levels. Farm-level slaughter cattle price changes typically lead wholesale beef price changes by 2 to 3 weeks. Similarly, wholesale beef price changes typically lead price changes at the retail level by 3 to 4 weeks.


Effect Of Limit-Fed, High Energy Growing Rations On The Performance Of Feedlot Steers, G. Goldy, B. Downey, K. Bolsen, Jack G. Riley Jan 1988

Effect Of Limit-Fed, High Energy Growing Rations On The Performance Of Feedlot Steers, G. Goldy, B. Downey, K. Bolsen, Jack G. Riley

Kansas Agricultural Experiment Station Research Reports

Steers red high-concentrate limit-fed rations were more efficient during growing than steers fed silage plus grain at 25% of their dry matter (DM) intake, or silage only. The limit-fed cattle also tended to gain faster (P<.10) and were more efficient (P<.05) during the finishing phase and did not have the expected depressed DM intakes compared to cattle fed the other growing-phase rations. Steers fed barely had lower DM intakes (P<.05) but gained more efficiently (P<.05) than those fed grain sorghum.


Daily Or Weekly Rotational Feeding Of Bovatec®- And Rumensin®/Tylan® To Cattle On A Steam-Flaked Corn Finishing Ration, Robert T. Brandt Jr. Jan 1988

Daily Or Weekly Rotational Feeding Of Bovatec®- And Rumensin®/Tylan® To Cattle On A Steam-Flaked Corn Finishing Ration, Robert T. Brandt Jr.

Kansas Agricultural Experiment Station Research Reports

One hundred sixty-five crossbred steers averaging 823 lb were utilized to evaluate the daily or weekly rotational feeding of ionophores. Treatments were (g/ton of feed, 90% dry basis): 1) Bovatec (B; 30), 2) Rumensin plus Tylan (RT; 25 and 10, respectively), 3) treatments one and two in a daily rotation (D), and 4) treatments one and two in a weekly rotation (W). Steers fed RT consumed less (P<.05) dry matter than B, D>or W steers. No differences (P>.15) in daily gain were observed, suggesting that the increased consumption by B, D) and W steers was accompanied by an al teration in passage ...


Effect Of Tetronasin On Frothy Bloat In Cattle Caused By High-Grain Diet, L.R. Neibarger, Tiruvoor G. Nagaraja Jan 1988

Effect Of Tetronasin On Frothy Bloat In Cattle Caused By High-Grain Diet, L.R. Neibarger, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

Feeding Tetronasin reduced incidence of frothy bloat in cattle fed a high-grain diet. The effective dose was 0.25 mg/kg body weight when administered prior to the onset of frothy bloat. At 0.15 mg/kg body weight, the antibiotic was less effective but the degree of bloat was considerably less than that of steers fed no antibiotic. Tetronasin also reduced the severity of bloat in steers that were already bloating prior to its administration.

Experimental Induction And Monitoring Of Liver Abscesses In Cattle With Ultrasonography, K.F. Lechtenberg, T.B. Avery, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

We have demonstrated that ultrasonography can be used to visualize liver abscess in live cattle. We have also developed a nonsurgical method of catheterizing the bovine portal vein and experimentally inducing liver abscesses by inoculating the portal vein with Fusobacterium necrophorum bacteria.


Evaluating The Availability Of Nutrients For Maintenance And Growth In Ruminants, K. Gross, D. Harmon, T. Avery Jan 1988

Evaluating The Availability Of Nutrients For Maintenance And Growth In Ruminants, K. Gross, D. Harmon, T. Avery

Kansas Agricultural Experiment Station Research Reports

Two experiments were performed with mature wether lambs to evaluate availability of selected nutrients and volatile fatty acids for maintenance and growth. We used a technique in which known amounts of volatile fatty acids were infused into the rumen and casein into the abomasum. Sampling portal blood allowed measurement of nutrients absorbed across the gastrointestinal tract. Approximately 49, 62, and 21% of the infused acetate, propionate, and butyrate, respectively, were absorbed across the gastrointestinal tract.


Testing Feedstuffs Using Near-Infrared Reflectance Spectroscopy (Nirs), P.C. Dubois, L.H. Harbers Jan 1988

Testing Feedstuffs Using Near-Infrared Reflectance Spectroscopy (Nirs), P.C. Dubois, L.H. Harbers

Kansas Agricultural Experiment Station Research Reports

Over 16 years ago, an analytical instrument was developed that could rapidly determine the concentration of organic compounds from the spectra produced by the bonding between certain molecules. The instrument is based on the principle that those molecules absorb electromagnetic radiation in the infrared region. Compounds may be quantitated by using a computer to compare absorption bands in the near-infrared spectrum to those from a large calibration set of known composition. Peaks from compounds such as water, protein, fat, and carbohydrate may be translated into nutrient components such as moisture, crude protein, crude fat, acid detergent fiber, etc. all this ...


Effect Of Environmental Temperature And Inoculants On The Fermentation Of Alfalfa And Forage Sorghum Silages, K. Bolsen, A. Laytimi, L. Nuzback, R. Hart Jan 1988

Effect Of Environmental Temperature And Inoculants On The Fermentation Of Alfalfa And Forage Sorghum Silages, K. Bolsen, A. Laytimi, L. Nuzback, R. Hart

Kansas Agricultural Experiment Station Research Reports

The inoculants, TriLac ®and Ecosyl® increased the rate and efficiency of the ensiling process in both high (50%) and low (32.5%) dry matter alfalfa, regardless of temperature. In both alfalfa trials, the inoculated silages had significantly lower pH, acetic acid, ethanol, and ammonia-nitrogen values and higher lactic acid values than their control counterparts. The inoculants worked equally well when fermentation was at 60 or 90 F. Although similar effects were obtained with forage sorghum, the differences were not as pronounced as those for the alfalfa silages.


Relationship Between Agronomic And Silage Quality Traits Of Forage Sorghum Cultivars, J. White, K. Bolsen, B. Kirch Jan 1988

Relationship Between Agronomic And Silage Quality Traits Of Forage Sorghum Cultivars, J. White, K. Bolsen, B. Kirch

Kansas Agricultural Experiment Station Research Reports

Results from two trials evaluating 11 forage sorghums as silage crops indicated that silage quality traits of voluntary intake, digestibility, and crude protein content were linearly associated with the agronomic characteristics of days to half bloom and plant height. Intake was negatively associated with plant height (r = -.49); digestibility was negatively associated with days to half bloom (r = -.39) and plant height (r = -.49); and crude protein was negatively associated with days to half bloom (r = - .51) and plant height (r = -. 71). Within the same cultivar, but between years, voluntary intake varied by as much as 30 percent, digestibility by ...


Yield, Chemical Composition, And Feeding Value Of Winter Cereal Silages And Hays: A 3 Year Study, S. Azimi, K. Bolsen, A. Laytimi, S.H.M. Esmail, J. Hoover, Q.K. Ye Jan 1988

Yield, Chemical Composition, And Feeding Value Of Winter Cereal Silages And Hays: A 3 Year Study, S. Azimi, K. Bolsen, A. Laytimi, S.H.M. Esmail, J. Hoover, Q.K. Ye

Kansas Agricultural Experiment Station Research Reports

Three trials were conducted to compare silage and hay yields and feeding values of winter cereal foraged harvested in the boot and dough stages of maturity. Included were triticale; common rye; Kanby barley; and Centurk, Arkan, and Bounty 205 wheats. As expected, forage dry matter (DM) yields were higher at the dough stage then boot stage, and silage yields tended to be higher than those for hay. In Trials 2 and 3 (1986-87), barley and rye forage yields were lower than wheat yields. In all three years, wet weather conditions made hay-making difficult. In Trial 1, cattle performance from dough ...


Sunflower Oil Seeds In Nursery Pig Diets, G E. Fitzner, Robert H. Hines Jan 1988

Sunflower Oil Seeds In Nursery Pig Diets, G E. Fitzner, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Two hundred forty pigs were used to evaluate the use of various amounts (0, 10, 15, 20, 25%) of black sunflower oil seeds in weanling pig diets. After 14 days, no significant differences were found between any of the dietary treatments in feed intake (FI), average daily gain (ADG), or feed efficiency (F/G). At the conclusion of the 5-wk study, no differences were found in FI, ADG, or F/G between those dietary treatments containing 0, 10, and 15% sunflower seeds. However, in those diets containing 20 and 25% sunflower seeds, there were linear (p<.05) reductions in FI and ADG. These results indicate that sunflower seeds, when finely ground using a hammermill with a 1/8 in screen, can be used in diets for weanling pigs up to 15% of the diet with no reduction in performance.; Swine Day, Manhattan, KS, November 17, 1988
