The single-output production function has long been regarded as one of the principle limitations of the econometric approach to technical efficiency measurement. If one wished to investigate efficiency in a multiple-output industry using econometric methods one would usually either: (a) aggregate outputs into a single index of output (e.g., total revenue or a multilateral Tornqvist output index); or (b) attempt to model the technology using a dual cost function. The first of these methods require that output prices be observable (and reflect revenue maximising behaviour), while the latter approach requires an assumption of cost-minimising behaviour. There are a number of instances, however, when neither of these requirements are met (the public sector contains many examples). In this study we outline the recently developed distance function solution to the multi-output problem. The method is illustrated using data on European railways. Output-orientated, input-orientated and constant returns to scale distance functions are estimated using corrected ordinary least squares. The distance function estimates are also compared with production function estimates involving aggregate output measures. These comparisons indicate that, for the case of European railways, a production function involving a multilateral Tornqvist output index exhibits substantially less aggregation bias relative to a production function that uses total revenue as a measure of aggregate output.

During this investigation, which involved 58 Belgian White and Blue double-muscled calves affected by a naturally occurring Acute Respiratory Distress Syndrome, the clinical efficiency of a 5-HT2 receptor blockade with metrenperone (group A) was compared to the efficiency of a non-steroidal (flunixine meglumine--group B) and a steroidal (prednisolone sodium succinate--group C) antiinflammatory drug. Each animal of this trial was treated with ceftiofur sodium as antimicrobial agent. A clinical score and a breathing score were calculated at each step of the investigation period, i.e. before (T0) and 1 hour (T1), 12 hours (H), 24 H, 48H and 168 H (T3) after the first treatment, the interval 12H-48H being considered as period T2. Three clinical parameters were also taken into account separately: rectal and peripheral temperatures and heart rate. A significant improvement of the clinical score was registered at T2 in group A and at T3 in groups A and B, while this score did not significantly change in group C. In group A, the breathing score was significantly improved at T2 and T3, but not in groups B and C. Peripheral and rectal temperatures recorded at T1 were, in group A, significantly increased and decreased respectively, but not significantly changed in groups B and C. The proportions requiring change of treatment during the investigation period were significantly (P = 0.022) different in the three groups, being 5.6, 21.4 and 50.0% in groups A, B and C respectively.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Three experiments were performed to assess the ability of a Lactobacillus plantarum probiotic combined with a xylanase to reduce the effects of S. typhimurium infection in broiler chickens from 1- to 30- or 42-d-old. Chicks were challenged at 3-d-old with 108 or 105 cfu S. typhimurium/chick. Four diets were studied: a wheat-based diet (C+) supplemented with 0.1 g/kg xylanase (E), or 106 cfu/g or L. plantarum (P), or both (PE). Uninfected chicks fed the C diet were used as negative control (C-). Six or 8 chicks were housed per cage with 9 cages/treatment. Growth performance and feed conversion ratio (FCR) were recorded weekly. In experiment 1, bacterial enumeration in caeca was achieved using the fluorescent in situ hybridization technique. Salmonella enumeration was realized in excreta by microbiological cultures (Exp. 2 and 3). Nutrient digestibilities and AMEn were determined in experiment 3 from d 35 to d 39. Infection with S. typhimurium led to a significant decrease in the daily weight gain (DWG) by 23.6% to 32.8%, whereas FCR was increased by 1.0% to 19.7%. Chickens fed the PE diet showed significantly improved performance in comparison with C+ birds (DWG: +12.5% in Exp. 1; FCR: -2.1-8.6%), and in comparison with the P and E treatments (DWG: +6.3-8.3% in Exp. 1; FCR: -2.7-6.4%). In experiment 3, the FCR was significantly improved by 3% with the PE diet in comparison with C- chickens. The PE combination tended to restore a microflora similar to that of uninfected broilers, whereas the P and E diets had less of an effect on the profile of bacterial communities. At slaughter age, Salmonella contamination was reduced by 2.00 and 1.85 log cfu for the E and PE treatment, respectively. The PE diet significantly reduced the crude fat digestibility by 9.2%, in comparison with the C+ chickens. These results suggest that combination between L. plantarum and a xylanase as feed additive could be effective for reduction of detrimental effect following S. typhimurium infection of broilers.
