Effect Of Summer Grazing On Crude Protein And Digestibility Of Winter Diets Of Cattle In The Nebraska Sandhills, Dale Downs, Don C. Adams, Terry J. Klopfenstein, Walter H. Schacht, Patrick E. Reece
Nebraska Beef Cattle Reports
Twenty-one pastures (three pastures/ treatment) were used in a two-year study to determine the effects of summer grazing on winter diet quality of Sandhills range. Summer grazing treatments consisted of no summer grazing (control) and June or July grazing at three stocking rates. After summer grazing, pastures were then diet sampled using esophageally fistulated cows in November, January and March following summer treatments. Year and sampling date had a significant effect on CP and IVDMD of winter range diets, whereas summer grazing treatments did not have a large impact.
Regulation Of Lh Secretion By Progesterone In Heifers, Karol Fike, Brad Lindsey, Ellen G. M. Bergfeld, Freddie Kojima, Jorge Quintal, Eraldo Zanella, Eric Melvin, Michael Wehrman, James E. Kinder
Regulation Of Lh Secretion By Progesterone In Heifers, Karol Fike, Brad Lindsey, Ellen G. M. Bergfeld, Freddie Kojima, Jorge Quintal, Eraldo Zanella, Eric Melvin, Michael Wehrman, James E. Kinder
Nebraska Beef Cattle Reports
Heifers experienced either a: 1) large magnitude of change in progesterone; 2) medium magnitude of change in progesterone; or 3) small magnitude of change in progesterone. During the 24 hours following the progesterone shift, heifers with the large magnitude progesterone shift had a greater LH pulse frequency than heifers with a medium or small magnitude of shift in progesterone. Despite the large or medium magnitude progesterone shift, LH pulse frequency did not differ from heifers in which a small change in progesterone occurred. We conclude that amount of progesterone in circulation is more important in regulation of LH secretion than …
Comparative Calf Grazing Of Corn And Soybean Residues, D. J. Jordon, Terry J. Klopfenstein, Mark Klemesrud
Comparative Calf Grazing Of Corn And Soybean Residues, D. J. Jordon, Terry J. Klopfenstein, Mark Klemesrud
Nebraska Beef Cattle Reports
A grazing trial was conducted in the winter of 1996-97 to compare the feeding value of soybean stubble to that of cornstalks. Irrigated bean residues were stocked at 0.5 animals/acre, while irrigated corn residues were stocked at 1.2 animals/acre. Calves grazing cornstalks gained (0.17 lb/day) faster (P = .003) than calves consuming soybean stubble (-0.03 lb/day). In addition, calves grazing cornstalks remained in fields 14 days longer. Diet samples were collected on both corn and soybean residues. Ruminally fistulated steer calves grazing bean stubble consumed diets high in crude protein (12- 25%), but low in organic matter digestibility (40-46%). Calves …
Lime Filtrate As A Calcium Source For Finishing Cattle, Mark Klemesrud, Terry J. Klopfenstein, Todd Milton
Lime Filtrate As A Calcium Source For Finishing Cattle, Mark Klemesrud, Terry J. Klopfenstein, Todd Milton
Nebraska Beef Cattle Reports
Finishing diets containing wet corn gluten feed were fed to 128 yearling steers to evaluate inclusion of lime filtrate as the source of supplemental calcium. Lime filtrate supplied 0, 50, 100 and 150% of the base calcium level of .70%, with limestone supplying the remainder. While dry matter intake was reduced for the 100% level of calcium from lime filtrate (P<.10), average daily gain and feed efficiency were not different from the limestone control. The 150% level of calcium from lime filtrate did reduce average daily gain and feed efficiency (P<.10).
Nutrient Balance On Nebraska Feedlots, Richard K. Koelsch, Gary Lesoing
Nutrient Balance On Nebraska Feedlots, Richard K. Koelsch, Gary Lesoing
Nebraska Beef Cattle Reports
A balance between the nutrient inputs and the managed nutrient outputs balance was constructed for 16 Nebraska feedlots to provide insight to potential environmental risks. Substantial nitrogen and phosphorus imbalances were observed for many participating feedlots. Size of the livestock operation and the degree of integration of livestock with a cropping operations provided only limited explanation concerning nutrient balance variations observed among the feedlots. Substantially improved nutrient balances were achieved by those feedlots marketing manure nutrients to off-farm customers. A “sustainable” nutrient balance appears possible for larger feedlots actively marketing manure nutrients.
In Situ Method For Estimating Forage Protein Degradability, Ryan Mass, Greg Lardy, Rick Grant, Terry J. Klopfenstein
In Situ Method For Estimating Forage Protein Degradability, Ryan Mass, Greg Lardy, Rick Grant, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Four experiments including vegetative and dormant forages tested modifications of the in situ neutral detergent fiber nitrogen (NDFN) method of estimating forage undegraded intake protein (UIP). Experiments 1, 2 and 3 tested bag size, closure, rinsing, density, and reflux conditions. None of the modifications affected in situ NDFN content. Experiment 4 compared rates of in situ NDFN digestion calculated with or without correction for undegradability. A close relationship exists between rates calculated by the two methods. Modifications make the improved in situ NDFN method a more desirable means of estimating forage UIP than the standard method.
Cull Dry Edible Beans In Growing Calf Rations, Ivan G. Rush, Burt Weichenthal, Brad Van Pelt
Cull Dry Edible Beans In Growing Calf Rations, Ivan G. Rush, Burt Weichenthal, Brad Van Pelt
Nebraska Beef Cattle Reports
Including cull dry edible beans into diets for steer calves in two yearly trials produced slightly different results. In the first year, calculated net energy levels were higher in diets with 5 or 10% dry beans and daily gains were equal or better than for the no-bean diets. In the second year, with equal net energy values in rations containing 0, 7.5 or 15% dry beans, daily gains and feed intake decreased linearly with dry bean additions. Feed efficiency was improved as bean level increased.

Crude protein of wet corn gluten feed is degraded extensively in the rumen. Thus, protein supplementation is an important consideration when feeding wet corn gluten feed, especially in receiving diets.
Cysteine From Feather Meal And Sulfur Amino Acid Requirements For Growing Steers, Mark Klemesrud, Terry J. Klopfenstein
Cysteine From Feather Meal And Sulfur Amino Acid Requirements For Growing Steers, Mark Klemesrud, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Ninety individually fed steers were used to determine how cysteine from feather meal could replace dietary methionine in meeting their requirements for sulfur amino acids. Treatment proteins included blood meal, blood meal plus incremental levels of feather meal or blood meal plus incremental levels of rumen-protected methionine. Addition of sulfur amino acids to blood meal from feather meal or rumen-protected methionine improved average daily gain (P < .05). Rumen-protected methionine elicited a greater gain response than feather meal (P < .05). Feather meal can provide some of the sulfur amino acids lacking in blood meal. However, additional methionine may further improve performance.

Effect Of Rumensin And Feed Intake Variation On Ruminal Ph, Rob Cooper, Terry J. Klopfenstein, Rick Stock, Cal Parrott, Dan Herold
Nebraska Beef Cattle Reports
Six ruminally-fistulated steers were used to evaluate the effect of Rumensin and feed intake variation on ruminal pH. Steers were adapted to a 92.5 percent concentrate diet and then subjected to three levels of intake variation: ad libitum, intake variation of 2 lb/day, and intake variation of 4 lb/day. Feed intakes and ruminal pH were monitored continuously throughout the entire trial. Results indicate that Rumensin reduced acidosis by elevating average ruminal pH and decreasing are of ruminal pH below 5.6. In addition, Rumensin stabilized rate of intake and daily ruminal pH fluctuation at the high level of intake variation.
