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 Jan 1992

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 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 Jan 1992

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.

Beef Empire Carcass Merit Days Index System (1992), T.H. Powell, S.D. Laudert, R.W. Lee, G. Seibert, John A. Unruh, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Kansas State University, in cooperation with the Beef Empire Days committee, developed a new beef carcass index system for 1991, incorporating yield and quality traits as indicators of carcass merit. Development of the system considered current industry and consumer demands in a critical evaluation of final carcass ranking. The index starts from 100 points and applies positive and negative adjustments for hot carcass weight; ribeye area; adjusted 12th rib fat thickness; percent kidney, pelvic, and heart fat; and quality grade. The index was first used in 1991.

Effect Of Feed Additives On Shipping Shrinkage Of Yearling Heifers (1992), F.K. Brazle Jan 1992

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.

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 Jan 1992

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 …

Heritabilities And Genetic Correlations Of Ultrasound-Measured Ribeye Area With Other Performance Traits In Brangus Cattle (1992), M.Z. Johnson, R.R. Schalles, W. Olson, Michael E. Dikeman Jan 1992

Heritabilities And Genetic Correlations Of Ultrasound-Measured Ribeye Area With Other Performance Traits In Brangus Cattle (1992), M.Z. Johnson, R.R. Schalles, W. Olson, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Heritabilities and genetic correlations for ultrasound-measured ribeye area and fat thickness, as well as growth traits and scrotal circumference, were determined using performance records of 1613 Brangus calves born from 1987 to 1990. Moderate heritabilities of .39 for weaning and .40 for yearling ultrasound- measured ribeye area indicate that selection to change these traits should be effective. The positive, and generally large, genetic correlations between ultrasound-measured ribeye areas and growth traits indicate that genetic change of these traits can be made in tandem. The low heritability (.14) of fat thickness, the small amount of fat, and the lack of variation …

Evaluation Of 20 Corn Hybrids For Silage Agronomic Characteristics (1992), R.N. Sonon, B.S. Dalke, R. Suazo, L. Pfaff, K.K. Bolsen

Kansas Agricultural Experiment Station Research Reports

Twenty corn hybrids were grown under irrigation and harvested at 90 % of the kernel milk line. Hybrid had a significant effect on plant height, whole-plant dry matter (DM) and DM yield, grain yield, stover yield, and plant part proportions. The highest whole-plant DM (45.9%) was for Cargill 7997, whereas the lowest was for Cargill 4327 (30.1%). Cargill 8427 and Pioneer 3245 had the highest wholeplant DM and grain yields, whereas Cargill 4327 was lowest. Grain yield and the percentage of grain in the whole-plant DM increased as the plant height increased.

A total of 1,350 pigs was used in three growth trials to determine the influence of weaning weight and average daily gain during the first week postweaning on subsequent growth performance. Average initial weight and age were 13.7 lb and 21 d, respectively. Pigs were weighed on d 0, 7, 28, and 56 postweaning in all three trials. Pigs were also weighed at market in trial 1. Weaning weight influenced postweaning growth performance such that each additional pound at weaning translated into approximately 2 lb by d 56 postweaning and 4 lb at market. These results indicate the importance of …

The Effect Of Moist And Dry Extrusion Processing On Growth Performance And Nitrogen Digestibility In The Early-Weaned Pig (1992), K G. Friesen, L J. Kats, Jim L. Nelssen, Robert D. Goodband, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

One hundred pigs (initially 13.0 lb and 21 d of age) were used to assess the differences between moist and dry extruded soybean meal in diets for early-weaned pigs. Dietary treatments included: 1) corn+ dried skim milk+dried whey+casein, 2) corn+soybean meal, 3) corn+dry extruded soybean meal, and 4) com+moist extruded soybean meal. The diets were formulated to contain 1.4% lysine and 24.4% lactose. Soybean meal (with or without extrusion processing) replaced milk protein on an equal lysine basis. Experimental diets were fed for the entire 28 d experiment. On d 14, fecal samples were collected to determine apparent DM and …
