Effect of wheat bran and wheat : barley ratio in pelleted feed on Salmonella prevalence and productivity of finishers

The effect on the prevalence of Salmonella and productivity of diets with varying wheat: barley ratios and with added wheat bran for finishers (30-100 kg live weight) was studied in one herd. The diets were provided as expanded and pelleted feed and fed to six groups with 384 pigs/group divided into 24 replicates. The proportion of wheat: barley was: Group I: I 00:0, group 2: 75:25, group 3: 50:50, group 4: 25:75, group 5: 0:100. Group 6 contained 85% wheat and 15% wheat bran. The pigs were fed ad libitum as dry feed

Effect of pelleting and use of lactic acid in feed on Salmonella prevalence and productivity in weaners

The effect of the feed\u27s form and of acidification was studied in one herd with weaners (approx. 7-30 kg). The test comprised a total of 232 pigs/group allocated to 30 replicates. Weaners were purchased from three different herds that all had a recognized Salmonella problem. The test was carried out as a randomised 2x2 factorial design with the factors meal vs. pelleted feed and-/+ 2.8% lactic acid added to the feed. Addition of 2.8 % of lactic acid reduced the number of Salmonella positive faecal pen samples. There was no significant effect of feeding meal feed compared to pelleted feed on Salmonella. The microbial results showed a reduced population of coliform bacteria in the digestive tract when acid was added to the diet. There was a higher water binding capacity and a higher dry matter (DM) concentration when using meal feed compared to pelleted feed. The viscosity in the stomach was higher in the groups given feed added acid compared to feed without acid. The production value (expresses the achieved productivity) was significantly higher in the groups receiving feed with added lactic acid. Feeding meal feed also resulted in a higher production value compared to pelleted feed. On the basis of this test, the best advice against Salmonella in weaners is to use a high concentration of lactic acid in the feed

The Social Life of Time and Methods: Studying London’s Temporal Architectures

This paper contributes to work on the social life of time. It focuses on how time is doubled; produced by and productive of the relations and processes it operates through. In particular, it explores the methodological implications of this conception of time for how social scientists may study the doubledness of time. It draws on an allied move within the social sciences to see methods as themselves doubled; as both emerging from and constitutive of the social worlds that they seek to understand. We detail our own very different methodological experiments with studying the social life of time in London, engaging interactive documentary to elucidate nonlinear imaginaries of space-time in London’s pop-up culture (Ella Harris) and encountering time on a series of walks along a particular stretch of road in south east London (Beckie Coleman). While clearly different projects in terms of their content, ambition and scope, in bringing these projects together we show the ability of our methods to grasp and perform from multiple angles and scales what Sharma calls ‘temporal architectures’. Temporal architectures, composed of elements including the built environment, commodities, services, technologies and labour, are infrastructures that enable social rhythms and temporal logics and that can entail a politicized valuing of the time of certain groups over others. We aim to contribute to an expanded and enriched conceptualisation of methods for exploring time, considering what our studies might offer to work on the doubled social life of time and methods, and highlighting in particular their implications for an engagement with a politics of time and temporality
