A trial was conducted to evaluate the teat conditioning efficacy of one experimentalformula when used post-milking. The trial consisted of two pens, where the samepre-milking teat disinfectant was used. The same experimental post milking teatdisinfectant was used on the leftquarters for both pens. However, two differentcontrol products were used on the rightquarters, one for each pen. The study lasted 4weeks for one pen and 8 weeks for the second pen. Teat skin and teat endroughness were scored for each teat 2X/week. A total of 75 cows from one penand 67 cows from the second pen were scored during the study period, but only 19cows from one pen and 30 cows from the second pen had full records for analyses.Results showed no concerning teat skin condition irritation events. There were nodifferences between products in teat end condition.

An ongoing two-year trial is being conducted to evaluate the effects of three different methods of initiating forage stockpiling on the quality and mass of forage available over the winter months (October through January). Methods of initiating stockpiling were spring strip-grazing, summer strip-grazing, and summer hay harvest. Forage mass, nutritional, and weather data were input into a ration balancing program with supplemental feed provided to maintain a body condition score (BCS) of five throughout the winter for fall-calving beef cows. Partial budget models were used to evaluate costs associated with the different treatment methods and compared to a standard winter hay feeding regime in a drylot scenario. Spring strip-grazing generated the greatest stockpiled forage mass compared to all other treatments, but also had the lowest dry matter digestibility across sampling dates. There were no differences in crude protein (CP) content among different methods of initiation. The carrying capacity of drylot models was greatest but did not differ between stockpiling models. There was a tendency for drylot models to incur greater total costs ($/ac) than stockpile models. There were no statistical differences in total cost ($/ac) between models using stockpiled forage grazing by different methods of initiation and no statistical differences in gross ($/hd/d) or net ($/hd/d) costs across treatments. While spring strip-grazing resulted in greater forage mass, the quality of this forage was lower than summer treatments. With similar costs, the lower yields from summer stockpiling models (strip-grazing or hay harvest) could be compensated for by the higher nutritional quality of the forage.

Sequencing technology allows us tosee how the gene expression of each genechanges under different treatment conditions. In this study, chicks of two inbred lines were challenged with Newcastle Disease Virus (NDV), a pathogen with devastating impacts on poultry throughout the world. At each of the three time points post-infection, one-third of the chicks were sacraficed and their lungs were harvested. When comparing males and females infected with NDV, differences in gene expression that were predicted to impact growth and apoptosis were identified. Differences between the response of males and females to viral challenges could be useful information for production operations. The interaction between production traits and immune related traits require further study.
