Conjunctival lipid granulomas in a cat

A 12-year-old, neutered male cat was examined because of a persistent serous ocular discharge from the left eye. Three, pale cream, 1-4 mm lesions were detected in the palpebral conjunctivae of the left eye. The surgical excision of the lesions resulted in complete resolution of the epiphora. Histological examination confirmed that the lesions were lipid granulomas but the aetiology and pathogenesis of them were not determined. No disease conditions which result in primary or secondary hyperlipoproteinaemia were detected.     

A technique for the conduct of nutritional balance experiments in horses

Standardbred geldings were used in a number of nutritional balance experiments. These consisted of 28-day cycles each of an 18-day equilibration period in yards and a 10-day settling and collection period in metabolism crates. The crates were made of galvanised metal tubing over wooden flooring covered by rubber matting and rubber sheets. Total faeces were collected in trays at the rear of crates and total urine by canvas funnels slung beneath the sheath of each horse.     

Lung histopathology,radiography, high-resolution computed tomography,and bronchio-alveolar lavage cytology are altered by Toxocara cati infection in cats and is independent of development of adult intestinal parasites

This study presents clinical findings after oral ingestion of Toxocara cati eggs which resulted in rapid pulmonary lung migration and parenchymal disease, noted on clinically relevant diagnostic methods. Further, the study investigated the efficacy of pre-infection applications of preventative medication on larval migration through the lungs. A third aim of the study was to determine if adult cats infected with T. cati developed lung disease. Cats in infected groups were administered five oral doses of L3 T. cati larvae. Four-month-old specific pathogen free (SPF) kittens were divided into three groups (six per group): an infected untreated group, an uninfected untreated control group, and an infected treated group (topical moxidectin and imidacloprid, Advantage Multi for Cats, Bayer Healthcare LLC). Six 2- to 3-year-old adult multiparous female SPF cats were an infected untreated adult group. The cats were evaluated by serial CBCs, bronchial–alveolar lavage (BAL), fecal examinations, thoracic radiographs, and thoracic computed tomography (CT) scans and were euthanized 65 days after the initial infection.     

Comparison of a pasture-based system of milk production on a high rainfall, heavy-clay soil with that on a lower rainfall, free-draining soil

The objective of this study was to compare the biological and economic efficiency of a seasonal pasture‐based spring calving system of milk production on a high‐rainfall, heavy‐clay soil [Kilmaley (KMY)] to that on a lower‐rainfall free‐draining soil [Moorepark (MPN)] in Ireland. The physical performance data were obtained from a 3‐year study (1998–2000) carried out at both sites. Analysis of the system of milk production at the two sites was undertaken using the Moorepark Dairy System Model. Herbage dry‐matter production was greater at the MPN site with a greater proportion being produced between 1 September and 1 May. On average, over the 3 years, the system of milk production at the MPN site had a higher stocking rate (2·34 vs. 1·89 cows ha^?1), higher milk production per cow (6421 vs. 5781 kg per cow), longer grazing season (250 vs. 149 d) and a higher proportion of the diet of the herd from grazed grass (0·70 vs. 0·40) than at KMY. Economic analysis showed that, in a 468 100 kg European Union milk quota scenario, the profitability at the MPN site was €28 417 greater than at the KMY site. At similar milk production per cow it was €19 138 greater. Monte Carlo simulation showed that the MPN site was stochastically dominant over the KMY site. Sensitivity analyses showed that farm profit was most sensitive to changes in milk price. The results also indicated that milk production in the future may not be sustainable economically on high‐rainfall, heavy‐clay soils in Ireland.     

It’s not all about the money: understanding farmers’ labor allocation choices

Using a nationally representative survey of farm operators in Ireland, this study examines the effect of non-pecuniary benefits from farm work on labor allocation choices. Results suggest that non-pecuniary benefits affect both the decision to enter the off-farm labor market and also once that decision is made, the amount of time spent working off-farm. We find our derived variable representing non-monetary benefits associated with farm work to have a substantial impact similar to the effect of other more widely reported personal and farm structural variables such as the age of the farm operator, farm size, and farming system. The existence of these non-pecuniary benefits serves to increase the implied wage to farmers for their farm work. This in turn can lead to allocations of labor that would seem suboptimal from a purely financial point of view. Rural development policies aimed at creating off-farm opportunities could fail unless returns to off-farm work are high enough to compensate the farmer for losing the benefits associated with the farming lifestyle. From a methodological perspective, our analysis indicates that failure to model off-farm labor allocation choices as a two-part process may lead to some incorrect conclusions regarding the effect of certain explanatory variables. Outside of explaining farmers’ off-farm labor supply it would be useful to incorporate farmer perceptions regarding the non-pecuniary benefits from farming in economic models of farm behavior across a range of activities as this could lead to much more accurate predictions of farmers’ responses to policy changes.     

Circumferential mural bands in the small intestine causing simple obstructive colic: a case series

REASONS FOR PERFORMING STUDY: Circumferential mural band (CMB) in the small intestine is an emerging condition in Ireland. The clinical presentation is a simple obstruction of the small intestine of unknown aetiology. HYPOTHESIS: Horses affected with CMB in the small intestine have a good prognosis following surgical decompression into the caecum. METHODS: A retrospective study was carried out and 28 cases identified from 559 colic surgeries performed over a 5.5 year period. An exploratory celiotomy was performed in every case. A simple obstruction at the mid or distal jejunum was identified caused by a CMB, which was multiple in some cases. All of the horses except 2 had undergone a regular anthelmintic programme. RESULTS: Manual decompression of the small intestine into the caecum resulted in resolution of the simple jejunal obstruction. A constricted segment of small intestine was resected in one case, as the degree of constriction was severe. A full thickness biopsy was taken from another case. Histopathology was performed on both samples. All horses recovered from surgery and were discharged from the hospital 7-32 days post operatively. Short-term complications were observed. Survival rate was 100% at long-term follow-up. Histopathology showed inflammatory infiltration in the submucosa, muscularis and serosa with eosinophils predominating. Parasites were not detected. CONCLUSION AND POTENTIAL RELEVANCE: Small intestine circumferential mural bands have a good prognosis after surgical decompression of the small intestine into the caecum.
