Effect Of Harvest Method On Digestibility Of Corn Residue, Tasha M. King, Melissa L. Jolly-Breithaupt, Jana L. Gramkow Gramkow, Terry J. Klopfenstein, Jim C. Macdonald

Nebraska Beef Cattle Reports

Corn residues can be an economical forage source for producers and advanced harvest methods have increased the quality of baled residue. A digestion study was conducted to evaluate the effects of harvest method of corn residues (low- stem, highstem, and conventional) on digestibility in lambs. Samples from total fecal collection were dried 1 of 3 ways to determine effects on digestibility estimates. Corn residue containing low- stem had greatest overall digestibility with high- stem residue being intermediate and conventional harvesting having the lowest digestibility. Drying method had no effect on digestibility estimates.

Comparison Of Titanium® 5 Ph- M Versus Titanium® 5 Plus Nuplura® Ph With The Presence Or Absence Of Monensin On Health And Performance Of Newly Received Feedlot Calves Fed Ramp®, Robert M. Jones, Curtis J. Bittner, F. Henry Hilscher Hilscher, Mallorie F. Wilken, Rick Stock, Galen E. Erickson

Nebraska Beef Cattle Reports

A receiving study was conducted to evaluate the effects of RAMP® with Rumensin® concentration (0 or 25.0 g/ton) given with one of two viral vaccinations (Titanium® 5 PH- M or Titanium® 5 plus NUPLURA® PH) on steer growth performance and morbidity. There were no significant vaccine by diet interactions observed. Neither vaccine treatment nor Rumensin® level affected intake, gain, or feed conversion. Vaccine type did not affect first pull (P = 0.19) or second pull morbidity rates (P = 0.52). These findings suggest that neither vaccine type nor Rumensin® concentration had any effect on steer growth performance or morbidity rate.

Nebraska Beef Cattle Reports

Changes in in vitro organic matter digestibility and digestible organic matter of corn residue were evaluated throughout the fall grazing and spring grazing seasons. In vitro organic matter digestibility and digestible organic matter were greatest at the beginning of fall grazing and declined over time. Slight weathering resulted in lower quality corn residue available at the beginning of spring grazing compared to the beginning of fall grazing. The in vitro organic matter digestibility of available residue declined 21% over the fall grazing season and 51% throughout the spring grazing season. As the availability of nutrients declines over time, adjustments in …

Statistics Used In The Nebraska Beef Report And Their Purpose

Nebraska Beef Cattle Reports

The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore he/ she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description …

Effect Of Heifer Development System On Reproduction And Subsequent Gain As A Pregnant Heifer, Shelby A. Springman, Hazy Rae Nielson, Tonya L. Meyer, Mike Kirby, Jim Teichert, Richard N. Funston

Nebraska Beef Cattle Reports

Weaned heifers grazed corn residue, upland range, or were fed 1 of 2 drylot diets differing in energy. Heifer development diets did not impact their resulting AI or final pregnancy rates. Cost per pregnant heifer was similar among treatments. A subset of AI- pregnant heifers was placed in a Calan Broadbent individual feeding system during late gestation. As a pregnant heifer, feed efficiency was not impacted by development system. These results indicate producers may utilize their most readily available and/or cost- effective feed resources with no detriment to pregnancy rates or feed efficiency as first- calf heifers.

Influence Of Supplementing Diet With Microalgae (Schizochytrium Limacinum)On Growth And Metabolism In Lambs During The Summer, Eki̇n Sucu, Duygu Udum, Nazmi̇ye Güneş, Önder Canbolat, İsmai̇l Fi̇lya

Turkish Journal of Veterinary & Animal Sciences

The current experiment was conducted to examine the impact of a supplement of microalgae (Schizochytrium limacinum) on the performance, rumen fermentation, and blood metabolites in lambs during summer. Forty lambs were used in a 49-day experiment. The lambs were group-fed either a basal diet (alfalfa hay and concentrate, n = 20) or the basal diet along with 5 g/day microalgae (n = 20). Feed intakes were recorded daily and body weight (BW) was measured weekly. Overall, microalgae feeding increased (P < 0.05) the BW and average daily gain. There were no significant differences for average feed intake or feed efficiency (P > 0.05). Microalgae feeding decreased rumen pH (P < 0.05) and tended to reduce proportion of acetate (P < 0.1), while it increased total rumen volatile fatty acid concentration (8.6%; P < 0.01) and proportions of propionate (13.9%, P < 0.01) and valerate (P < 0.01; 26.5%) compared with the control animals. Microalgae feeding increased (P < 0.05) blood glucose (98.47 vs. 84.97 mg/dL) and insulin (64.14 vs. 29.26 ng/mL), whereas it lowered total cholesterol concentrations in blood (62 vs. 58 mg/dL, P < 0.1) compared with the control animals. The results of this study indicate that microalgae supplement influences productivity and enhances dietary energy utilization in lambs during the summer.

Turkish Journal of Veterinary & Animal Sciences

This study was planned to see the additive effects of various industrial residues including molasses, rice polish, and corn steep liquor for the bioprocessing of wheat straw (WS) through solid-state fermentation (SSF) using Arachniotus sp. as a fermenting agent. The performance of fungal-based WS (seed culture) was evaluated in terms of the favorable changes in crude protein (CP) contents. WS (5 g) was mixed with our selected carbon and nitrogen sources in a basal medium containing optimized salt concentrations to attain the desired level of water and nutrients. An increased (P < 0.0001) CP value was observed at a 25:1 C:N ratio and maximum fungal protein contents (13.40%) were found by mixing 0.4 mL of molasses, 0.8 g of rice polish, and 3.0 mL of corn steep liquor in treated WS at a setting time of 48 h in SSF. It was seen that the growth rate of Arachniotus sp. was greatly improved by the addition of our selected amounts of carbohydrate and nitrogen sources. Hence, our current results support the use of these economical byproducts for cheap biomass production.
