Effect Of Feed Additives On Shipping Shrinkage Of Yearling Heifers (1992), F.K. Brazle
Effect Of Feed Additives On Shipping Shrinkage Of Yearling Heifers (1992), F.K. Brazle
Kansas Agricultural Experiment Station Research Reports
Two studies were conducted to determine the effect of feed additives on the transit shrink of yearling cattle. In Trial I, 146 mixed-breed heifers were offered a mineral mixture containing either Terramycin® or Bovatec®, or without additive while grazing native grass pastures. Shrinkage after 300 miles in transit was lower (P.05). The small shrinkage differences observed in these two trials would not justify changes in the weighing practices of feeder cattle.
Effects Of Biomate® Inoculant And Dextrose On The Fermentation Of Alfalfa Silages (1992), C. Lin, K.K. Bolsen, J.E. Bradford, B.E. Brent, A.M. Feyerherm, W.R. Aimutis
Effects Of Biomate® Inoculant And Dextrose On The Fermentation Of Alfalfa Silages (1992), C. Lin, K.K. Bolsen, J.E. Bradford, B.E. Brent, A.M. Feyerherm, W.R. Aimutis
Kansas Agricultural Experiment Station Research Reports
This study documented once again that ensiling alfalfa is difficult and unpredictable. Adding 2% dextrose or Biomate® inoculant alone or in combination had little influence on the ensiling process but did improve fermentation efficiency somewhat. The pre-ensiling characteristics (i.e., dry matter (DM) and water soluble carbohydrate (WSC) values, buffering capacity, and epiphytic microflora) at the different cuttings and stages of maturity undoubtedly influenced the effectiveness of the two additives. Apparently, alfalfa often has too little WSC and too much buffering capacity to produce adequately preserved silage, especially when ensiled at a low DM content (less than 30 to 34%).
Effect Of Long-Acting Penicillin And Levamisole® On Gain And Health Of Stressed Calves (1992), F.K. Brazle
Effect Of Long-Acting Penicillin And Levamisole® On Gain And Health Of Stressed Calves (1992), F.K. Brazle
Kansas Agricultural Experiment Station Research Reports
Two studies were conducted to determine the effect of long-acting penicillin and/or levamisole injected at arrival or levamisole injected on day 1 and/or day 7 on the health and gain of newly received, highly stressed, light weight calves. Levamisole injected at arrival reduced (P<.05) sickness of newly arrived calves during the first 5 days. However, it did not reduce overall sickness during the receiving period. Long-acting penicillin injected at arrival did not reduce sickness, but did improve (P<.05) gain of calves during the growing period. The combination of levamisole and long-acting penicillin or the combination of levamisole on day 1 and day 7 did not reduce morbidity in these highly stressed calves.
Epiphytic Lactic Acid Bacteria Succession During The Pre-Ensiling And Ensiling Periods Of Alfalfa And Corn (1992), Chunjian Lin, B.E. Brent, K.K. Bolsen, Daniel Y.C. Fung
Epiphytic Lactic Acid Bacteria Succession During The Pre-Ensiling And Ensiling Periods Of Alfalfa And Corn (1992), Chunjian Lin, B.E. Brent, K.K. Bolsen, Daniel Y.C. Fung
Kansas Agricultural Experiment Station Research Reports
Twenty three species and 306 strains of epiphytic lactic acid bacteria (LAB) were found for two cuttings of alfalfa, each harvested at three stages of maturity, and three whole-plant corn hybrids. Epiphytic LAB counts were low and variable on the standing crops, particularly on alfalfa. Wilting increased LAB numbers slightly for alfalfa, but the chopping process increased counts dramatically for both crops. Lactobacillus plantarum, Pediococcus pentosaceus, Enterococcus faecium, and E. faecalis were predominant on both standing crops. The changes in LAB caused by wilting or chopping were mainly proportional changes in the four dominant species. Once the crops were ensiled, …
Evaluation Of Inoculant-Treated Corn Silages (1992), K.K. Bolsen, D.G. Tiemann, R.N. Sonon, R.A. Hart, B. Dalke, J.T. Dickerson, C. Lin
Evaluation Of Inoculant-Treated Corn Silages (1992), K.K. Bolsen, D.G. Tiemann, R.N. Sonon, R.A. Hart, B. Dalke, J.T. Dickerson, C. Lin
Kansas Agricultural Experiment Station Research Reports
Whole-plant corn silages treated with either Pioneer 1174® or Biotal® inoculants were preserved more efficiently than control silages. They had slightly higher dry matter (DM) recoveries; more lactic acid; higher lactic to acetic acid ratios; and less acetic acid, ethanol, and ammonia-nitrogen. Laboratory silo results showed that both inoculated silages produced lactic acid faster than control silages during the first 7 days and had more desirable fermentation profiles at the end of 90 days. Applying 5 or 10 times the recommended rate of Biotal inoculant had only a small and nonsignificant effect on rate and efficiency of fermentation. Yearling steers …
Evaluation Of Interseeded Grain Sorghum And Soybeans As A Silage Crop (1992), L.H. Harbers, K.K. Bolsen, H. Hartadi
Evaluation Of Interseeded Grain Sorghum And Soybeans As A Silage Crop (1992), L.H. Harbers, K.K. Bolsen, H. Hartadi
Kansas Agricultural Experiment Station Research Reports
Dry matter yield of grain sorghum alone averaged more than 1.0 ton per acre higher than that of intercropped grain sorghum-soybeans in both 1988 and 1989. All silage yields were lower in 1989 because of drought. Grain sorghum silage had less NDF and ADF, but intercropped silages had over 4 percentage units more crude protein. Digestibility coefficients for crude protein, NDF, and ADF tended to favor intercropped silages, but yearling steer performance favored grain sorghum silage. Studies over 4 years (1986 to 1989) suggest that intercropping might be more beneficial for dairy cattle producers than beef producers.
Rate And Extent Of Losses From Top Spoilage In Pilot-Scale, Horizontal Silos, J.T. Dickerson, K.K. Bolsen, B.E. Brent, C. Lin, John E. Boyer
Rate And Extent Of Losses From Top Spoilage In Pilot-Scale, Horizontal Silos, J.T. Dickerson, K.K. Bolsen, B.E. Brent, C. Lin, John E. Boyer
Kansas Agricultural Experiment Station Research Reports
Corn and forage sorghum silages were stored in pilot-scale silos for 180 days, and dry matter (DM) and organic matter (OM) recoveries and estimated OM recovery were measured at three depths within the top 3 ft. of silage. The unsealed silages deteriorated badly in the top 12 in. Actual DM and OM losses in the top 24 in. were higher in unsealed than sealed silages at each successive storage period (7 to 180 days). The unsealed silages began to deteriorate immediately in the top 12 in. in both crops, and deterioration progressed to the second 12 in. by 90 days …
Use Of Low-Level Grain Supplementation In An Intensive-Early Stocking Program: Influence On Daily Gain And Forage Production (1992), R.C. Cochran, E.S. Vanzant, Robert T. Brandt Jr., Clenton E. Owensby, Lisa M. Auen
Use Of Low-Level Grain Supplementation In An Intensive-Early Stocking Program: Influence On Daily Gain And Forage Production (1992), R.C. Cochran, E.S. Vanzant, Robert T. Brandt Jr., Clenton E. Owensby, Lisa M. Auen
Kansas Agricultural Experiment Station Research Reports
A 4-year experiment was conducted to evaluate the effect of increasing amounts of grain supplementation on steer gains and forage production in pastures managed under an intensive-early stocking system. Average daily gain tended to increase in direct proportion to increasing level of sorghum grain supplementation (2.19, 2.43 and 2.59 lb/day for the control, 2 and 4 lb/day supplement levels, respectively). The amount of grass remaining in the pastures at the end of the grazing season (approximately July 15) also increased in direct proportion to increasing sorghum grain supplementation. Forage remaining in the pastures at the end of the growing season …
Effect Of Supplemental Grain Sorghum And Overseeding With Ladino Clover On Grazing And Subsequent Feedlot Performance Of Steers Early-Intensively Grazed On Acremonium Coenophialum - Infected Tall Fescue Pastures (1992), K.P. Coffey, Joseph L. Moyer, Lyle W. Lomas, F.K. Brazle
Effect Of Supplemental Grain Sorghum And Overseeding With Ladino Clover On Grazing And Subsequent Feedlot Performance Of Steers Early-Intensively Grazed On Acremonium Coenophialum - Infected Tall Fescue Pastures (1992), K.P. Coffey, Joseph L. Moyer, Lyle W. Lomas, F.K. Brazle
Kansas Agricultural Experiment Station Research Reports
Eighty mixed breed steers (avg. wt. 560 lb.) were used to evaluate the effect on grazing gain and subsequent feedlot performance of different management options for steers early-intensively grazing Acremonium coenophialuminfected tall fescue pastures. Steers were allotted to pastures of infected fescue pastures or infected fescue overseeded with ladino clover and received no supplement or were offered grain sorghum at .25% of their body weight. Neither supplementation nor overseeding affected grazing or feedlot performance. However, grain supplementation on overseeded pastures reduced subsequent feedlot feed efficiency (P<.10). These management options did not substantially affect grazing or subsequent feedlot performance by steers early-intensively grazing infected fescue pastures.
Synchronization Of Estrus In Yearling Beef Heifers With The Mga®/Prostaglandin F2Α System: Iii. Timed Insemination After 72 Hours Of Estrous Detection (1992), Robert L. Larson, L.R. Corah
Synchronization Of Estrus In Yearling Beef Heifers With The Mga®/Prostaglandin F2Α System: Iii. Timed Insemination After 72 Hours Of Estrous Detection (1992), Robert L. Larson, L.R. Corah
Kansas Agricultural Experiment Station Research Reports
The percentage of heifers conceiving to artificial insemination (AI) following melengestrol acetate/prostaglandin F2"(MGA®/PG) estrous synchronization can be increased by mass insemination of all heifers not showing estrus by 72 h after PG. Inseminating at 12 h after estrus detection all heifers showing estrus within 72 h after PG; then inseminating those not detected in estrus by 72 h after PG as a group increased the proportion of heifers conceiving to AI by 10.8%.
Influence Of Source And Amount Of Dietary Protein On The Performance And Reproductive Function Of First-Calf Heifers (1992), W.C. Rusche, R.C. Cochran, L.R. Corah, Jeffrey S. Stevenson, D.L. Harmon
Influence Of Source And Amount Of Dietary Protein On The Performance And Reproductive Function Of First-Calf Heifers (1992), W.C. Rusche, R.C. Cochran, L.R. Corah, Jeffrey S. Stevenson, D.L. Harmon
Kansas Agricultural Experiment Station Research Reports
Increasing the amount of dietary protein above the NRC requirement increased weight gain of nursing first-calf heifers. Feeding a protein source with higher ruminal escape potential and increasing protein in the diet both improved calf gains. No significant changes in reproductive function or milk production were observed from either source or amount of dietary protein.
Effects Of Niacin And Aspirin On Serum Prolactin And Body Temperature Of Heifers Fed Endophyte-Infected Tall Fescue (1992), Robert L. Larson, L.R. Corah
Effects Of Niacin And Aspirin On Serum Prolactin And Body Temperature Of Heifers Fed Endophyte-Infected Tall Fescue (1992), Robert L. Larson, L.R. Corah
Kansas Agricultural Experiment Station Research Reports
Feeding niacin to cattle consuming endophyte (Acremonium coenophialum)-infected tall fescue elevated their serum prolactin concentrations to levels similar to those of heifers fed hay containing a low content of endophyte. Heifers fed high-endophyte hay, with or without aspirin, had lower serum prolactin concentrations than heifers fed low-endophyte fescue hay (P<.1). Compared to control cattle fed high-endophyte hay, neither niacin nor aspirin lowered morning or evening body temperatures during the period August 16 to September 4. Feeding aspirin did not lower body temperature or increase prolactin concentration in animals fed high-endophyte fescue forage. Some benefit was seen when niacin was added to the diet, as evidenced by higher (P<.01) prolactin concentrations; however body temperature was not lowered.
Factors Affecting Variability In Feedlot Steer Profits (1992), Michael R. Langemeier, J. Mintert, Ted C. Schroeder
Factors Affecting Variability In Feedlot Steer Profits (1992), Michael R. Langemeier, J. Mintert, Ted C. Schroeder
Kansas Agricultural Experiment Station Research Reports
This study examined the relative importance of price and animal performance factors on cattle finishing profitability. Using data from a single feedlot, sale prices, feeder prices, and corn prices explained 90 to 95% of the variation in steer profits. About 50% of the variability was explained by fed cattle prices alone. Because sale, feeder, and corn prices have a large impact on profits per head, cattle feeders should attempt to manage the risks associated with these three factors.
A Comparison Of Beef Flavor Intensity Among Major Muscles (1992), C.F. Carmack, J.R. Schwenke, Curtis L. Kastner, Michael E. Dikeman
A Comparison Of Beef Flavor Intensity Among Major Muscles (1992), C.F. Carmack, J.R. Schwenke, Curtis L. Kastner, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Twelve muscles from eight Select/Choice grade steers were evaluated for beef flavor intensity, tenderness, and juiciness. Sample steaks were cut, and evaluation was performed by a five-member professional panel. The biceps femoris ranked highest in beef flavor intensity but was not different (P>.05) from the psoas major, gluteus medius, semimembranosus, and triceps brachii (scores of 7.8, 7.5, 7.4, 7.4, and 7.3, respectively). The rectus femoris, longissimus lumborum, serratus ventralis, infraspinatus, semitendinosus, deep pectoral, and supraspinatus were less intense in beef flavor (7.1, 7.1, 7.0, 6.8, 6.8, 6.7, and 6.6, respectively). The psoas major was most tender (P.05). Muscles from …
Influence Of Frequency Of Energy Supplementation On Utilization Of Early-Summer, Tallgrass Prairie Forage (1992), J.L. Beaty, R.C. Cochran, B.A. Lintzenich, E.S. Vanzant
Influence Of Frequency Of Energy Supplementation On Utilization Of Early-Summer, Tallgrass Prairie Forage (1992), J.L. Beaty, R.C. Cochran, B.A. Lintzenich, E.S. Vanzant
Kansas Agricultural Experiment Station Research Reports
Fifteen ruminally cannulated beef steers were used in a pasture supplementation experiment to determine the effects of frequency of energy supplementation on intake and digestion of tallgrass prairie forage during early to mid-summer. Steers grazed a common pasture and were assigned to the following treatments: no supplement (control); 4 lb rolled sorghum grain/head/day; 9.3 lb grain/head/3 times weekly. Steers in the two supplemented groups consumed the same amount of sorghum grain/head/week. In general, supplementation was not harmful (P =.17) to forage intake. However, providing supplement 3 times weekly tended (P =.11) to depress forage intake compared with daily supplementation. Although …
