Evaluating Serving Capacity Of Yearling Beef Bulls - A Field Trial, G. Boyd, L. Corah
Evaluating Serving Capacity Of Yearling Beef Bulls - A Field Trial, G. Boyd, L. Corah
Kansas Agricultural Experiment Station Research Reports
Results from two trials showed that serving capacity (SC) can be successfully evaluated in yearling beef bulls under field conditions and is influenced by sire line (P<.01). Also, providing sexual experience to low SC yearling bulls can improve SC and should be a standard part of the test. Scrotal circumference and breeding soundness examination scores, both traditional measures of bull fertility, were unrelated to SC.
Comparative Feeding Value Of Grain Sorghum And Corn In Beef Cattle Diets, G. Goldy, K. Bolsen, Jack G. Riley
Comparative Feeding Value Of Grain Sorghum And Corn In Beef Cattle Diets, G. Goldy, K. Bolsen, Jack G. Riley
Kansas Agricultural Experiment Station Research Reports
Homozygous yellow endosperm grain sorghum had no advantage in feeding value over heterozygous yellow endosperm hybrids (P>.05). A heterozygous yellow endosperm hybrid, Funk's 550, had larger kernels (P<.001) and when dry rolled, produced more fine particles (P<.01). This may explain its trend toward improved feed efficiency, higher DM digestibility, and greater in vitro VFA production compared with the other dry processed grain sorghum hybrids tested. Our results do not support the traditional 12 to 16% price discount for grain sorghum relative to corn.
Effects Of Pneumo-Guard H® And Vitamin E On Gain And Health Of Stockers Purchased As Steers And Bulls, F. Brazle
Kansas Agricultural Experiment Station Research Reports
Pneumo-Guard H® and injectable Vitamin E did not improve cattle gain or reduce treatments required per animal during a 29-day receiving trial. Stockers purchased as steers gained faster (P<.001) and required fewer (P<.001) treatments per animal than bulls castrated on arrival.
Feeding Value Of Wheat And Sorghum Grain As Indicated By Absorbed Nutrients, K.L. Gross, D.L. Harmon, T.B. Avery
Feeding Value Of Wheat And Sorghum Grain As Indicated By Absorbed Nutrients, K.L. Gross, D.L. Harmon, T.B. Avery
Kansas Agricultural Experiment Station Research Reports
Steers fed diets based on dry-rolled wheat or sorghum grain alone or combined (50:50) showed no differences in net portal fluxes of glucose, L-lactate, ammonia, urea, or α-amino nitrogen. Portal blood flow was increased in steers fed the 50:50 diet. Total volatile fatty acid flux into the portal blood tended to be lower for steers fed the sorghum grain diet, which may partially explain the lower feeding value of sorghum grain compared to wheat or the two grains combined.
Measurement Of The Binding Properties Of Meat Used In Restructured Beef Products, S.J. Goll, Curtis L. Kastner
Measurement Of The Binding Properties Of Meat Used In Restructured Beef Products, S.J. Goll, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
The dried weight of the material washed from meat surfaces by distilled water closely paralleled the binding strength between meat particles as measured by tensile strength testing. Sponges added to meat pieces during mixing were a poor estimation of protein extraction and binding strength.
Relationship Of Age At Puberty And Postpartum Interval To Estrus In Angus X Hereford And Brahman X Hereford Females, D.J. Patterson, L.R. Corah, J.R. Brethour, W.R. Negus
Relationship Of Age At Puberty And Postpartum Interval To Estrus In Angus X Hereford And Brahman X Hereford Females, D.J. Patterson, L.R. Corah, J.R. Brethour, W.R. Negus
Kansas Agricultural Experiment Station Research Reports
Records of age at puberty (AAP) and postpartum interval to estrus (PPI) for heifers calving first at 2 years of age were used to determine the relationship between the two reproductive parameters. In Brahman x Hereford (BxH) females, there was no relationship between AAP and PPJ. In Angus x Hereford (AxH) females, PPI increased as AAP decreased. The data suggest that heifers heavier at weaning reach puberty younger, but PPJ may be longer following their first calving. Heifers larger at weaning may need to be managed differently to improve performance during the first postpartum period.
Effects Of Rumensin® Ruminal Delivery Devices In Grazing Cattle On Subsequent Feedlot Performance, Jack G. Riley, B. Cochran, Ronald V. Pope
Effects Of Rumensin® Ruminal Delivery Devices In Grazing Cattle On Subsequent Feedlot Performance, Jack G. Riley, B. Cochran, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
Rumensin® Ruminal Delivery Devices put in place 76 days prior to steers entering a feedlot resulted in an average reduction in daily dry matter intake of 3.6% and a small 1.8% increase in daily gain during a controlled 28-day feeding phase. All steers were fed an 85% concentrate feedlot diet fortified with 30g/ton of Rumensin® and 10 g/ton of tylan®.
Influence Of Ionophore Addition To A High-Concentrate Diet On Net Nutrient Absorption In Steers, D.L. Harmon, K.L. Gross, T.B. Avery
Influence Of Ionophore Addition To A High-Concentrate Diet On Net Nutrient Absorption In Steers, D.L. Harmon, K.L. Gross, T.B. Avery
Kansas Agricultural Experiment Station Research Reports
Feeding the ionophores monensin and lasalocid In a high-concentrate diet resulted in gut tissues utilizing less glucose. Monensin caused less urea to be recycled. The new, experimental ionophore (lCI 139603) resulted in an increased net absorption of acetate. Thus, ionophores may differ in how they execute their effects on feed efficiency.
Additive-Treated Corn Silages For Growing Cattle, K. Bolsen, H. Ilg, B. Kirch, A. Laytimi, Lyle W. Lomas
Additive-Treated Corn Silages For Growing Cattle, K. Bolsen, H. Ilg, B. Kirch, A. Laytimi, Lyle W. Lomas
Kansas Agricultural Experiment Station Research Reports
Whole-plant corn silages were treated with USO3M or Silo-Best Soluble® in one trial and with Garst M-74® in a second trial. In Trial 1 all three silages were well preserved and moderately stable in the air. USO3M silage lost less dry matter during fermentation than control or Silo-Best silages. Cattle fed the USO3M silage made 7.6% faster gains and were 5.2% more efficient than those fed the control silage. Cattle performance with the Silo-Best Soluble and control silages was similar. In trial 2, heifer gains were nearly identical for both control and Garst M-74 silages.
Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope
Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
Stocking rate in an intensive-early stocking system (1.25, 1.50, or 1.76 acres per steer) did not influence steer gains. Available forage on loamy upland sites was lower after steer removal on July 15 for the highest stocking rate. However, after late season rest, available forage was similar for all stocking rates. Steer gains were consistently greater for groups implanted with Compudose® (estradiol 78β or Compudose plus a Rumensin® (monensin) ruminal delivery device. The Rumensin device alone was successful in increasing average daily gain only at the highest stocking rate.
Effect Of Commercial Inoculants On The Fermentation Of Alfalfa, Corn, Forage Sorghum, And Triticale Silages, K. Bolsen, H. Ilg, A. Laytimi, R. Hart, V. Chain, L. Nuzback, Daniel Y.C. Fung
Effect Of Commercial Inoculants On The Fermentation Of Alfalfa, Corn, Forage Sorghum, And Triticale Silages, K. Bolsen, H. Ilg, A. Laytimi, R. Hart, V. Chain, L. Nuzback, Daniel Y.C. Fung
Kansas Agricultural Experiment Station Research Reports
Fourteen commercial inoculants were evaluated in seven trials using alfalfa, corn, forage sorghum, and triticale silages. Microbial profiles of the inoculants and of the crops differed widely. Viable lactic acid bacteria (LAB) supplied per gram of fresh crop by the inoculants ranged from less than 103 to over 103. Only the alfalfas had 10 or fewer LAB per gram of crop when the forages were treated and as a result, fermentation responses were excellent for those inoculants that supplied 10 or more LAB per gram of treated crop. Corn and triticale underwent a very rapid fermentation rate with very little …

Effect Of Maturity At Harvest On Yield, Composition, And Feeding Value Of Forage And Grain Sorghum Silages, S. Hamma, B. Kirch, B. Downey, J. White, K. Bolsen
Kansas Agricultural Experiment Station Research Reports
In the last 2 years, three trials were conducted to determine the influence of hybrid and stage of maturity at harvest on silage yield, composition, and nutritive value for 15 forage and nine grain sorghum hybrids. Agronomic data, such as days to half bloom, plant height, and whole-plant dry matter (OM) and grain yields, were also obtained. In Trial 1, Pioneer 947, Acco Paymaster 351, and DeKalb 25E forage sorghum hybrids had different whole-plant OM and crude protein (CP) contents. Whole-plant OM increased, whereas CP generally decreased with advancing maturity. Hybrid affected both DM intake and CP digestibility. Results indicated …
Implant Comparisons In Grazing And Finishing Spayed Heifers, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards
Implant Comparisons In Grazing And Finishing Spayed Heifers, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards
Kansas Agricultural Experiment Station Research Reports
Heifers that were flank-spayed plus rumen-ovarian autografted (FS+A) responded similarly to Ralgro®, Synovex-H®, and Synovex-S® implants on' pasture. Grazing heifers spayed by the Kimberling-Rupp technique also responded similarly to Synovex-H and Synovex-S implants. During the finishing phase, heifers implanted with Synovex-S gained 5.7% faster than heifers implanted with Ralgro, and those implanted with Synovex-H were intermediate in performance. There was no statistical interaction between spaying method and implant treatment during either the grazing or finishing phases.
Effect Of Bovatec® Level In Supplemental Feed On Performance And Forage Utilization Characteristics Of Wintering Beef Cattle, R.C. Cochran, L.R. Corah, K.A. Jacques, T.B. Avery, K.O. Zoellner, J.F. Higginbotham
Effect Of Bovatec® Level In Supplemental Feed On Performance And Forage Utilization Characteristics Of Wintering Beef Cattle, R.C. Cochran, L.R. Corah, K.A. Jacques, T.B. Avery, K.O. Zoellner, J.F. Higginbotham
Kansas Agricultural Experiment Station Research Reports
Various levels of lasalocid (Bovatec®) added to a protein supplement did not improve weight or condition change of beef cows grazing poor quality winter pasture. Similarly, calf birth weight and most forage utilization characteristics (e.g., intake, passage rate, and fermentation characteristics) were not altered by Bovatec level. Although forage digestibility was influenced by Bovatec level, changes were not sufficient to influence performance characteristics.
Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully
Effect Of Several Spaying Methods On Grazing Heifer Gains, Gerry L. Kuhl, T. Goehring, B. Ritter, S. Laudert, W. Mccully
Kansas Agricultural Experiment Station Research Reports
Several spaying and ovarian autografting methods were tested in three field trials with 658 grazing heifers. None of the techniques examined were found to have a beneficial effect on heifer gains compared to intact controls. Heifers' initial weight, frame size, and body condition score were associated with cattle performance; however, their relative impact on gains varied across the three trials.
Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem, E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques
Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem, E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques
Kansas Agricultural Experiment Station Research Reports
Supplementing beef steers consuming immature bluestem with 0, 1, 2, or 4 lbs of sorghum grain daily did not affect forage intake. Thus, total intake increased as level of grain increased. Total dry matter, cell wall, and starch digestibilities were mildly depressed with increasing grain. Rumen fill and rates of passage were similar for all treatments, and differences in rumen fermentation characteristics were minimal.
Influence Of Rumen Bypass Fat Fed In A Range Supplement On The Performance Of Cows And Calves Grazing Bluestem Range, L. Corah, B. Cochran, D. Harmon, T. Goehring

Both feed additive mixtures increased heifer gains about .3 lb per day compared to controls supplemented with a simple mineral mixture.
Feeding And Managing Early Lactation Cows (1987), James R. Dunham
Feeding And Managing Early Lactation Cows (1987), James R. Dunham
Kansas Agricultural Experiment Station Research Reports
Feeding and managing dairy cows during the prepartum and early lactation periods have more effect on total lactation yields than all other factors. It is during this time that the pattern of milk production is established for the entire lactation. The full production potential of high producing cows cannot be realized unless these periods are given special consideration.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;
Effect Of Production On Reproduction (1987), Edward P. Call
Effect Of Production On Reproduction (1987), Edward P. Call
Kansas Agricultural Experiment Station Research Reports
The genetic antagonsim that exists between production and reproduction is overcome by sound management practices. Kansas Holstein herds were ranked by quartile and analyzed by comparing various reproductive traits. Higher producing herds suffered less reproductive loss based upon the factors considered. The most significant differences concerned the average days dry, average days open on cows not yet serviced, percent of cows open more than 120 days since fresh, and average age at first calving. An adequate record system will identify potential reproductive problems, and a sound Preventive Herd Health Program (PHHP) will minimize actual losses from disease and cows not …
Concentrations Of Progesterone And Conception Rates In Holstein Heifers After Hcg Administration During The First 3 Weeks After Estrus (1987), R.E. Stewart, M.O. Mee, Jeffrey S. Stevenson
Concentrations Of Progesterone And Conception Rates In Holstein Heifers After Hcg Administration During The First 3 Weeks After Estrus (1987), R.E. Stewart, M.O. Mee, Jeffrey S. Stevenson
Kansas Agricultural Experiment Station Research Reports
We conducted two experiments to determine the effects of administering human chorionic gonadotropin (hCG) on day 4 or on days 15, 16, and 17 after estrus on conception rates and progesterone secretion by the corpus luteum in Holstein heifers. In the first experiment, 60 heifers received hCG or saline on day 4 after estrus and AI. Conception rates were similar between groups. Concentrations of progesterone were increased in treated pregnant and nonpregnant heifers 7 and 14 days after treatment compared with pregnant and nonpregnant controls. In the second experiment, 62 heifers received hCG or saline on days 15, 16, and …
Evaluation Of A Calf Starter Supplement (1987), J.L. Morrill, P.G. Reddy
Evaluation Of A Calf Starter Supplement (1987), J.L. Morrill, P.G. Reddy
Kansas Agricultural Experiment Station Research Reports
An experimental calf starter made from a pelleted commercial type supplement and feeds readily available on the farm was compared to a conventional pelleted calf starter in an attempt to demonstrate an economical alternative to commercial calf starter. Calves fed the experimental starter consumed as much starter and gained as much weight as calves fed the conventional starter, thus demonstrating a potential for savings on feed cost. The project is continuing in an attempt to improve the starter composition.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;

Glucose, Starch, And Dextrin Utilization In The Small Intestine Of Steers (1987), K.K. Kreikmeier, D.L. Harmon, T.B. Avery, Robert T. Brandt Jr.
Kansas Agricultural Experiment Station Research Reports
Holstein steers (775 lbs) were surgically fitted with abomasal and ileal cannulae, portal and mesenteric venous catheters, and an elevated carotid artery. These steers were used to study starch digestion in the small intestine. Glucose, corn starch, and corn dextrin were infused into the abomasum at various levels and ileal digesta samples were collected. Disappearance of carbohydrate (CHO) in the small intestine was determined using Cr:EDTA as an indigestible marker. Blood samples were collected from the portal vein and carotid artery during carbohydrate infusion. Blood flow was determined, and net glucose absorption across the small intestine was calculated. Glucose infusions …

Effect Of Ruminal Protozoa On Performance Of Early-Weaned Calves (1987), K.L. Anderson, Tiruvoor G. Nagaraja, J.L. Morrill, P.G. Reddy
Kansas Agricultural Experiment Station Research Reports
Twenty newborn bull calves assigned to two groups, protozoa-free or protozoa-inoculated, were used to determine the effects of ruminal protozoa on performance of early weaned calves. Calves in the protozoa group were inoculated via stomach tube with a suspension of ruminal protozoa at weekly intervals until a viable population was established. Calves were evaluated weekly for weight gain and feed intake. Feed intake and weight gain were not significantly different between the groups but tended to be higher in protozoa-inoculated than protozoa-free calves.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;
Early Lactation Somatic Cell Count Should Be Low (1987), James R. Dunham
Early Lactation Somatic Cell Count Should Be Low (1987), James R. Dunham
Kansas Agricultural Experiment Station Research Reports
Cows and heifers in milk for fewer than 50 days, as shown on the DHIA Somatic Cell Count report, should have a lower average Somatic Cell Count than cows in milk for more than 300 days, if the dry cow mastitis treatment and management programs are effective. The DHIA Somatic Cell Count (SCC) average for a dairy herd is a good evaluation of a mastitis control program. Since leucocytes migrate to the mammary system during periods of subclinical mastitis, the SCC average indicates the amount of subclinical mastitis in a herd. A realistic goal for a herd average SCC is …

Relative Feeding Value Of Three Forage-Based Diets For Holstein Heifers (1987), John E. Shirley, J.L. Morrill, W.H. Carinder
Kansas Agricultural Experiment Station Research Reports
Soybeans interseeded with grain sorghum and harvested as a mixed forage silage crop can be used successfully as a feed for growing dairy heifers. However, daily gain is greater when grain sorghum silage plus alfalfa hay or prairie hay supplemented with milo grain and soybean meal is fed.Replacement heifer programs should be cost effective but yield a heifer large enough to be bred to calve by 24 months of age and with a well developed mammary gland relatively free of internal fat. A daily gain of 1.6 to 1.8 lbs appears to be optimum to achieve the desired bodyweight to …
Update On Heat Detection Aids (1987), Jeffrey S. Stevenson, Edward P. Call
Update On Heat Detection Aids (1987), Jeffrey S. Stevenson, Edward P. Call
Kansas Agricultural Experiment Station Research Reports
Poor heat detection is a major cause of reproductive failure in most dairy herds. About one-half of the heat periods are undetected, resulting in prolonged calving intervals. In many cases, the problem is serious enough that some producers have compromised their breeding goals by utilizing natural mating exclusively or maintaining clean-up bulls. The result of these compromises means loss in genetic superiority of future replacement heifers and the potential for serious injury or death of farm help or family.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;
