Thesis (MScAgric) -- Stellenbosch University, 1984. / INTRODUCTION: This study was initiated by the various reports of improved animal performance resulting from supplementary feeding of grazing ruminants and in this respect, it may be regarded as a feasibility study of the ability of the natural pasture at the applied stocking rates, to supply the animal with its nutrient requirements, since before providing the animal with supplementary nutrients, it is necessary to identify those which may possibly limit animal production. The criti= cal test of such a limiting nutrient would be an improved animal performance, resulting from supplementation of the nutrient suspected as being limiting, under grazing conditions.

The concentrations of calcium and phosphorus were determined in 12 llamas from the Condoriri Agricultural Experiment Center (Oruro Technical University) of Oruro, Bolivia during two seasons (wet and dry) and at three ages (newborn, juvenile, and adult). Samples of flesh were taken from the arm, leg, back, rib, and neck. Pasture samples (grassland and prairie) were used to determine the rate of biting of each animal studied. The blood samples were taken by extracting blood from a jugular vein. The minerals (Ca and P) in the flesh are highest in the wet season, 113.78 mg/100 g. The newborns were found to have the highest concentrations of minerals during the wet and dry season, 113.78 and 93.98 mg/100 g. The mineral concentrations of calcium and phosphorus for the newborns and adults were 120.58 and 144.5 mg/100 g. The lower concentration of juveniles had 7.52 mg/100 g of calcium in the meat and reported a 9.59 mg/100 g concentration during the wet season and 6.78 mg/100 g for the dry season. The juveniles and adults recorded higher concentrations of calcium with 9.2 and 8.78 mg/100 g with the newborns having a lower value of 6.58 mg/100 g. The phosphorus in the flesh was reported to be 9.59 mg/100 g for the wet season and 6.78 mg/100 g for the dry season. The concentration of the calcium and phosphorus in the grazed pasture during the wet and dry seasons was 0.56 and 0.12 % respectively. The females recorded higher concentrations of calcium and phosphorus with 0.38% while the males recorded only a 0.30% concentration. The calcium content is higher in the pasture (0.55%) than the phosphorus (0.13%). In the wet season the biomass contains 0.91% calcium and 0.22% phosphorus. During the dry season the high calcium content was 0.19% and for phosphorus it was 0.04%. The calcium and phosphorus exist in smaller quantities in the blood during the wet season (7.25 mg/dl) and greater quantities during the dry season (9.88 mg/dl). Juvenile females have a higher quantity of calcium (10.15 mg/dl) while newborns and adults have a lower quantity (9.52 and 7.2 mg/dl).
