Abstract

En Argentina, no existen datos regionales de intervalos de referencia de minerales en cerdos según las líneas genéticas actuales y distintas categorías de producción en sistema intensivo. Por ello, el objetivo del presente estudio fue determinar intervalos de minerales: calcio, fósforo, magnesio, sodio, potasio, hierro, cobre y cinc, en suero de cerdos en establecimientos del centro de Santa Fe y de Entre Ríos. Se trabajó con 300 muestras de sangre de cerdos sanos de dos líneas genéticas diferentes en las categorías de lechones recién nacidos, lechones destetados, hembras nulíparas gestantes seleccionadas fenotípicamente para la reposición del plantel, y hembras multíparas gestantes. Se determinaron las concentraciones séricas de los minerales por espectrofotometría de absorción atómica (FAAS) con un equipo Perkin Elmer modelo Analys 200, con métodos oficiales de AOAC. Se analizaron también muestras de agua. Los intervalos de referencia se calcularon utilizando parámetros paramétricos o no paramétricos dependiendo de la distribución de los datos. Los valores medios, medianas, valores mínimo y máximo e intervalos de referencia, para los distintos minerales en cada categoría productiva, se presentan en tablas. Los intervalos de referencia calculados serán útiles para el diagnóstico de deficiencias mineral y la vigilancia nutricional en cerdo de producción de carne. SUMMARY. Mineral reference intervals in confined swine with different genetic background and categories. In Argentina, there is no regional data on mineral reference intervals in swine, according to the genetic lines, categories of production in intensive systems. The objective of this study was to establish ranges of the following serum minerals: calcium, phosphorus, magnesium, sodium, potassium, iron, copper and zinc, in swine farmed in Santa Fe and Entre Ríos. Blood samples were collected from 300 healthy pigs of two different genetic lines belonging to the following categories: newborn piglets, weaned piglets, pregnant nulliparous females selected for re-stocking, and pregnant multiparous females. Serum concentrations of minerals were determined by atomic absorption spectrophotometry (FAAS) with a Perkin Elmer model Analys 200 and using official AOAC methods. Water samples were also analyzed. Reference intervals were calculated using parametric or nonparametric methods on basis of data distribution. Mean, median, minimum, maximum values and reference intervals for different minerals were tabulated. The reference intervals calculated in this study will be useful for the diagnosis of mineral deficiencies and nutritional monitoring in meat production pigs.

Abstract

Escalating wildfire frequency and severity, exacerbated by shifting climate patterns, pose significant ecological and economic challenges. Prescribed burns, a common forest management tool, aim to mitigate wildfire risks and protect biodiversity. Nevertheless, understanding the impact of prescribed burns on soil and microbial communities in temperate mixed forests, considering temporal dynamics and slash fuel types, remains crucial. Our study, conducted at the University of Tennessee Forest Resources AgResearch and Education Center in Oak Ridge, TN, employed controlled burns across various treatments, and the findings indicate that low-intensity prescribed burns have none or minimal short-term effects on soil parameters but may alter soil nutrient concentrations, as evidenced by significant changes in porewater acetate, formate, and nitrate concentrations. These burns also induce shifts in microbial community structure and diversity, with Proteobacteria and Acidobacteria increasing significantly post-fire, possibly aiding soil recovery. In contrast, Verrucomicrobia showed a notable decrease over time, and other specific microbial taxa correlated with soil pH, porewater nitrate, ammonium, and phosphate concentrations. Our research contributes to understanding the intricate relationships between prescribed fire, soil dynamics, and microbial responses in temperate mixed forests in the Southern Appalachian Region, which is valuable for informed land management practices in the face of evolving environmental challenges.

Abstract

The theme of this paper is the presence and role of women in the manufacturing industry in the Province of Lecce with special reference to textiles and clothing and footwear sectors. The objective is to analyse areas where women are most frequently found in the workplace, focusing on production of household textiles, underwear, rugs, tapestries, religious vestments, knitwear, socks, made-to-measure garments and shoes. The aim is to assess the role of women in these sectors at different places and times. The method of enquiry adopted made use of various resources: research based on bibliographical and statistical sources accessed via the web or available in the libraries of the University of the Salento, the provincial library, State Archives and municipal libraries. Further data was provided by the Lecce Chamber of Commerce, the Lecce offices of the Confederazione Nazionale dell’Artigianato (National Crafts’ Association), provincial professional associations and the provincial offices of the trade unions. Direct interviews were conducted and photographs taken.
