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.

Evaluation Of A New Single Implant Strategy Vs. Two Common Implant Strategies In Beef Finishing Steers, Cody A. Nichols, Judson Vasconcelos, Galen E. Erickson, Stephanie A. Furman, Justin J. Sindt, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
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.

LSU Master's Theses
Lactobacillus delbrueckii ssp bulgaricus LB-12, Streptococcus salivarius ssp thermophilus ST-M5 and Lactobacillus acidophilus LA-K are dairy cultures widely used in the fermentation of dairy products. Homogenization is an essential process in dairy industry for making several products. High homogenization pressures (>50 MPa) are used to create stable emulsion, inactivate the pathogens and increase the protease activity of dairy cultures. Sparse literature is available on the influence of low homogenization pressures, and their effect on beneficial characteristics of dairy cultures is not well understood. The objective of this study was to determine the effect of low homogenization pressures on acid …
