Critical Production

Abstract Supplementation strategies and nutritional management of ewes during critical production periods of breeding and gestation is an important consideration, particularly when ewes are on winter range. Clinical and subclinical trace mineral deficiencies at these times limit ewe productivity in these extensive environments. The objectives of this study were to (1) quantify mineral element concentrations of common forages on winter range, and (2) evaluate producer supplementation strategies using a survey. We hypothesized that mineral element concentrations in winter forages were inadequate to meet ewe requirements during critical production stages and shrub species would contain higher levels of macro- and micro-mineral element concentrations than grass species. Forage samples were collected from 25 ranches across Wyoming winter range and were compiled by species and analyzed for nutrient and mineral element composition; however, data presented herein represents the first year of data collection (12 of 25 ranches). Nutrient and mineral element concentration results indicated an effect in CP, Ca, P, K, Mg, S, Na, Zn, Cu, Se, Mn, and Mo concentrations between grass and shrub species (P < 0.05). Specifically, Mg and Mo concentrations were higher in grasses while the other mineral element concentrations were higher in shrubs. No effect was observed for Fe and Co concentrations between grass and shrub species (P = 0.37 and P = 0.29). Survey results revealed that 80% of ranches had more than 1000 sheep, and 47% of respondents utilized winter range for 131 to 170 day periods throughout production year. While on winter range the majority of producers (47%) supplement with a protein source. Additionally, 58% do not supplement white salt, while 47% supplement a complete trace mineral mix.

Suburban Site

The proposed approach based on compositional data analysis was applied on simultaneous measurements of the mineral element concentrations of PM10 and PM2.5 from a typical suburban site with and without a Saharan event. The suburban site is located in the city of Rome. The selected mineral elements were Al, Si, Ca, Fe, Ti, Mg, and Sr. The data relating to these elements are reported in a previous study. The considered elements are mainly related to mineral matter. The proposed approach allows statistically validating that the mineral element concentrations of PM during days with a Saharan event differ from those without a Saharan event in terms of mineral element composition and size distribution. In particular, the results showed that the compositional data analysis applied to simultaneous measurements of mineral element concentrations of PM10 and PM2.5 is a helpful technique that can be used to study environmental sites affected by natural sources such as Saharan events. Moreover, the presented technique can be handy in all those conditions where it is important to discriminate whether the occurrence of an exceedance or a violation of the daily limit value established for PM could also be due to natural sources.
