Nutrient Requirements of Domesticated Ruminants draws on the most up-to-date research on the energy, protein, mineral, vitamin and water requirements of beef and dairy cattle, sheep and goats. It defines the responses of animals, in weight change, milk production and wool growth, to quantitative and qualitative changes in their feed supply. It has particular application to grazing animals. Factors affecting the intake of feed are taken into account and recommendations are given according to the production systems being used; for instance, the feed intake of a grazing animal is affected by a larger number of variables than a housed animal. Examples of the estimation of the energy and nutrients required for the different production systems are given, as well as the production expected from predicted feed intakes. The interactions between the grazing animal, the pasture and any supplementary feeds are complex, involving herbage availability, diet selection and substitution. To facilitate the application of these recommendations to particular grazing situations, readers are directed to decision support tools and spreadsheet programs. Nutrient Requirements of Domesticated Ruminants is based on the benchmark publication, Feeding Standards for Australian Livestock: Ruminants, published in 1990 by CSIRO Publishing on behalf of the Standing Committee on Agriculture. It provides comprehensive and useful information for graziers, livestock advisors, veterinarians, feed manufacturers and animal nutrition researchers. The recommendations described are equally applicable to animals in feedlots or drought yards.

“…The same study further revealed that the total daily intake of metals by sheep can be as high as 1685 mg, 486 mg and 60 mg for lead (Pb), zinc (Zn) and copper (Cu), respectively. Another earlier study by [9] showed that grazing young sheep ingest soil F at moderate to high rates; in fact, an order of 69-184 mg F/day, for 63 days, was observed. These findings confirm the potential of soils in supplying F to animals.…”

Soil-plant-animal and soil-animal pathways are the principal routes through which trace element e.g fluorine (F) enters the animal body systems. It is believed that soils and herbage contaminated with such trace elements may, eventually, reflect in the bones and other animal tissues. However, the correlationship between soil F and Bone F among grazing animals has not been substantially, established. This study aimed at investigating the association between F concentration in soil to those found in the bones of sheep and cattle reared in metalliferous mining areas of the United Kingdom. The study area included Derbyshire, a site of fluorite (CaF 2) mineralization; Ceredigion and Mendips, sites of mostly galena (PbS) mineralization, the latter two sites used as control sites for this study. The analytical approach involved alkali fusion, perchloric acid digestion and sequential extraction procedures in determining total soil F, total bone F and soil bioavailable F, respectively. The spectrophotometric technique was then used to determine soil F from solution extracts. The results showed mean total soil F concentrations of 302.3 mg/kg, 175.4 mg/kg and 70.8 mg/kg in Derbyshire, Mendips and Ceredigion respectively. The same order was observed for bone F with as high as 218.3 mg/kg, 118.1 mg/kg and 88.9 mg/kg found in Derbsyhire, Mendips and Ceredigion respectively. Analysis of Spearman rank coefficients established that there is a moderate association between soil bioavailable F and bone F (r s =0.571), significant at p < 0.1; a conclusion suggesting possible high risk from F on animals grazing within heavily contaminated areas affected by historical F mining.

“…In the absence of industrial output and agricultural contamination, animals are typically introduced to excess fluoride via long-term (i.e., monthly or multi-annual; Grace et al, 2005) ingestion of geothermal waters and by foraging in enriched areas, such as those composed of volcanic soils (Shupe et al, 1984. Prehistoric bison regularly inhabiting and utilizing such environments, either continually or through the course of migration, may have invited toxicosis.…”
