Comparing Ensiled Or Fresh Mixed Wet Distillers Grains With Solubles With Straw At Two Inclusions In Growing Calf Diets, Crystal D. Buckner, Terry J. Klopfenstein, Galen E. Erickson, William A. Griffin, Joshua R. Benton
Nebraska Beef Cattle Reports
This study evaluated feeding ensiled or freshly mixed wet distillers grains with solubles (WDGS) with straw at 2 blends and the effect of an inoculum with the ensiled mixture on steer calf performance. Treatments included 30 or 45% WDGS (DM basis) mixed with straw and fed either as a fresh mix or ensiled with and without a microbial inoculum. No significant interactions were observed between type and level of mix. Steers fed the ensiled mixes had higher ADG and lower F:G compared to those fed the fresh mix.

Fiber Digestibility And Rumen Ph For Diets Containing Wet Corn Gluten Feed Or Wet Distillers Grains With Solubles, Crystal D. Buckner, Kelsey Rolfe, Nathan Meyer, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Seven ruminally cannulated steers were used to evaluate fiber digestibility and rumen pH for diets containing 35 or 88% wet corn gluten feed (WCGF) or 35% wet distillers grains with solubles (WDGS). These diets were top-dressed with or without a direct-fed microbial (DFM). Interactions were observed for DM and NDF digestibility. Feeding 88% WCGF decreased DM digestibility, but NDF digestibility increased especially with the DFM. Rumen pH was greatest for steers fed 88% WCGF and lowest for steers fed 35% WCGF.

Tympanic Temperature Of Steers Fed Different Levels Of Metabolic Energy Intake During Summer And Winter, Rodrigo A. Arias, Terry L. Mader
Nebraska Beef Cattle Reports
Tympanic temperatures (TT) of steers were recorded during July (8 days) and January (6 days). In each experiment, steers were fed 11, 18, or 25 Mcal/day ME in a roughage-based diet, or 18, 25, or 32 Mcal/day ME in a concentrate-based diet. Tympanic temperatures were greater during summer than during winter. Also, steers fed a concentrate diet had greater TT than those fed a roughage diet. Linear equations were obtained to estimate TT of cattle for summer and winter seasons. During the winter, TT response to MEI was dependent on the type of diet. Resultsdemonstrate that increases in the energy …

Nebraska Beef Cattle Reports
Anti-Müllerian Hormone (AMH) has been associated with follicle number and age of the ovary. Therefore, our hypothesiswas that AMH was a biomarker for both follicle number and ovarian function in the beef cow. Ovaries were collected by flank laparotomy. The number of follicles increased as cows aged from 1.5 to 6 years and began to decrease thereafter; however, the size of the ovary continued to increase with advanced age. Expression of the AMH gene increased with increasing follicle number in 2-year-old beef cows. These results suggest that heifers with larger ovaries will have greater numbers of follicles and greater productivity, …

Genetic Analysis Of Mature Size In American Angus Cattle, Marco G. Dib, L. Dale Van Vleck, Matthew L. Spangler
Nebraska Beef Cattle Reports
Genetic parameters for weights and heights of mature cows were estimated using a repeatability model from field data provided by the American Angus Association. The results showed that the heritabilities of both traits were large, and correlations between them were positive and strong. Selection on either trait should easily produce a response, and changing one should lead to a correlated response in the other. Genetic trend was generally for increasing cow weight over the last 25 years.

Supplementing Dried Distillers Grains To Steers Grazing Cool Season Meadow, William A. Griffin, Brandon L. Nuttleman, Terry J. Klopfenstein, L. Aaron Stalker, Richard N. Funston, Jacqueline A. Musgrave
Nebraska Beef Cattle Reports
Two experiments evaluated the performance response of supplementing dried distillers grains plus solubles (DDGS) to steers grazing cool season meadow. Steers were supplemented 0.0 or 0.6% of BW in Exp. 1, and 0.0, 0.6, or 1.2% of BW in Exp. 2. In Exp. 1, supplemented steers had 0.13 lb/day greater ADG. In Exp. 2, there was a linear response to supplementation level, with steers supplemented 1.2% of BW having greatest ADG. Diet samples indicate the differences were due to increased energy and not increased protein intake.

Relationship Of Metabolizable Protein Balance, Purine Derivative Excretion, And 3-Methyl Histidine Excretion To Feed Efficiency In Individually Fed Finishing Heifers, William A. Griffin, Kelsey Rolfe, Grant I. Crawford, Terry J. Klopfenstein, Galen E. Erickson, Phillip S. Miller, Ruth M. Diedrichsen
Nebraska Beef Cattle Reports
Individually fed heifers were used to determine the relationship of 3-methyl histidine, purine derivatives, and metabolizableprotein balance to feed efficiency. Heifers were fed finishing dietsthat were either deficient or sufficient in metabolizable protein. Urine samples were collected and analyzed for early, late, and entire feeding period concentrations of 3-methyl histidine, purine derivatives, and creatinine. Results from this study indicated a negative relationship between feed efficiency and metabolizable protein balance, and no relationship between 3-methyl histidine excretion and feed efficiency, suggesting that protein turnover and microbial protein synthesis are not related to feed efficiency

Nebraska Beef Cattle Reports
Calving records collected between 2000 and 2008 at the Gudmundsen Sandhills Laboratory, Whitman, Neb., were used to determine the effect of estrous synchronization on calving distribution and the impact of time of calving on carcass characteristics. More synchronized cows calved during the first 21 days compared to non-synchronized cows, and calves born to synchronized dams were heavier at weaning. Calves born in the first 21 days of the calving season had greater carcass weights, marblingscores, and yield grades than later born calves. In addition, the percentage of steers grading premium choice or greater and the total carcass value declined as …

Nebraska Beef Cattle Reports
A commercial feedlot experiment was performed to compare the effects of a Component TE-IS/TE-S with Tylan (TE-IS/S) implant strategy to a Component TE-200 with Tylan (TE-200) or a Revalor XS (Rev-XS) single implant strategy on performance and carcass characteristics of feedlot steers. Cattle receiving the TE-IS/S implants and the Rev-XS implant had greater (P < 0.05) final BW and lower F:G (P < 0.05) than the cattle that received the TE-200 treatment. Daily gain was improved (P = 0.04) when comparing TE-IS/S to TE-200, but intermediate for steers that received the Rev-XS treatment. Quality grade categories were unaffected by implant strategy. Cattle given TE-IS/TE-S had a greater number (P < 0.05) of yield grade 1 and 2 carcasses than other implant treatments, while cattle receiving TE-200 had greater (P < 0.01) yield grade 3 and 5 carcasses.

Nebraska Beef Cattle Reports
A commercial feedlot study compared effects of Revalor IS/Revalor S (RevIS-S) implant strategy to a Revalor XS (RevX) single implant strategy on performance and carcass characteristics of feedlot cattle. There were no differences (P > 0.90) in DMI, final BW, ADG, or F:G. Hot carcass weight, marbling score, 12th rib fat, LM area and calculated yield grade also were unaffected (P > 0.10) by implant strategy. The RevX treatment resulted in a greater (P < 0.01) percentage of Choice carcasses than RevIS-S. Cattle receiving Revalor XS performed similar to cattle implanted with RevIS-S using a traditional reimplant program.

A finishing trial was conducted to compare the response to three implant strategies on performance and carcasscharacteristics of feedlot steers: 1) ComponentTE-IS with Tylan followed with Component TE-S with Tylan (TE-IS/S); 2) Component TE-200 with Tylan (TE-200); or 3) Revalor XS (Rev-XS) single implant. Final BW, DMI and ADG were unaffected (P > 0.05) by implant strategy. Steers on the TE-IS/ S treatment had a lower (P < 0.01) feed:gain ratio (F:G) compared to those on the Rev-XS and TE-200 treatments. F:G calculated on a live basis was improved (P < 0.05) for reimplantedcattle compared to those on the TE-200 treatment; F:G for the Rev-XSwas intermediate. No differences (P > 0.05) were observed for HCW, 12th rib fat, percentage USDA Choice and calculated USDA yield grade among treatments. Cattle implanted with Rev-XS had greater (P < 0.05) marbling scores than those implanted with TE-IS/S. Carcasses from TE-IS/S implanted steers presented larger (P = 0.03) longissimus muscle areas than both the TE-200 and Rev-XS treatment groups. These results suggest that F:G was improved with reimplanting.
