2 pages., Comments on a widely distributed video showing mistreated cattle at a California meat packing plant. Examines the increasing complications of cattle processing and other factors that "haven't really been the focus on the ongoing investigation."
Abstract from UI electronic subscription., Authors use contingent valuation to determine the economic value of improving the welfare of farm animals and find that people are willing to pay extra on their weekly food bill to ensure that laying hens, broiler chickens, dairy cows and pigs have improved welfare conditions. "The benefits of improving animal welfare are shown to exceed the costs of implementing these schemes. We conclude that improving the standards of legislation for farm animal welfare so that all farm animals experience higher standards of welfare can be economically justified."
12 pages, Knowledge of how different management strategies affect gas production from livestock buildings can be helpful for emission predicting purposes and for defining mitigation strategies. The objective of this study was to statistically assess whether and how measured concentrations of ammonia (NH3), methane (CH4) and carbon dioxide (CO2) were influenced by milking frequency. Concentrations of gases were measured continuously by using infrared photoacoustic spectroscopy in the breeding environment of an open dairy barn located in Sicily in hot climate conditions. Data were acquired by specific in-field experiments carried out in 2016 and 2018, when milking sessions occurred twice a day (2MSs) and three times a day (3MSs), respectively. The number of the milking cows was 64 in both 2MSs and 3MSs. The results showed that concentrations of NH3, CH4 and CO2 were statistically influenced by the number of milking sessions. From 2MSs to 3MSs, NH3 concentrations were enhanced (p < 0.001) due to the higher cow’s activity. Conversely, gas concentrations of CH4 and CO2 were lower for 3MSs compared to those for 2MSs due to the effect of the different feeding frequency. Overall, the milking frequency influenced barn management and cow behaviour by modifying the level of gas concentrations in the barn environment.
26 pages, Proper calf care is important on dairy farms as management practices affect animal well-being and productivity as well as farm profitability. This article highlights areas of calf management needing improvement according to the results of a mixed-mode survey intended to provide a snapshot of calf management practices in Vermont. Areas for which improvement is needed aligned with farmers' identification of topics of interest and included calving management, nutrition (particularly neonatal feeding practices), and biosecurity (including vaccination). Extension professionals can draw on information about practices needing improvement and topics of interest to farmers to better position themselves to provide outreach tailored to the real and perceived needs of their clients.
