Six groups, each of six sheep, were fed in pens for 15 months on a ration of chaffed lucerne and wheaten hays. One group was offered rain-water to drink, another group was offered 1.30% sodium chloride, whereas the others were offered one of the following mixtures of sodium and calcium chlorides: 1.24 + 0.05, 1.19 + 0.10, l.09 + 0.20, and 0.98 + 0.30%. The intake of all saline solutions was higher than that of rain-water, ranging from 100% above for 1.30% sodium chloride to 20% above for 0.30% calcium chloride; the mean daily intakes for the entire experiment by the six groups were 2.6, 5.2, 4.6, 4.4, 3.8, and 3.11, respectively. The intake also increased in all groups with temperature, being 45–60% higher in the hottest months than in the coldest months. The saline drinking waters had no effect on the concentrations of potassium, magnesium, or chloride in the blood plasma, but did result, for a considerable portion of the experiment, in lower concentrations of sodium and higher concentrations of calcium in the plasma as compared with the concentrations of these electrolytes in the plasma of sheep drinking rain-water. None of the solutions used in the experiment had any adverse effect on the general health, food consumption, weight increase, or wool production of the sheep.

Six groups, each of six sheep, were fed in pens for 15 months on a ration of chaffed lucerne and wheaten hays. One group was offered rain-water to drink, another group was offered 1.30 per cent. sodium chloride, whereas the others were offered one of the following mixtures of sodium chloride and sodium sulphate: 1.22 + 0.10 , 1.14 + 0.20, 1.05 + 0.30, and 0.89 + 0.50 per cent. The intake of water containing 1.30 per cent. sodium chloride alone, or 0.10 or 0.50 per cent. sodium sulphate with sodium chloride, was higher than that of rain-water, and the intake was increased still further with 0.20 and 0.30 per cent. sodium sulphate; the mean daily intakes for the entire experiment by the six groups were 2.3, 3.8, 3, 6, 4.3, 4.2, and 3.71. respectively. The intake also increased in ell groups with temperature, being 30-60 per cent. higher in the hottest months than in the coldest months. The saline drinking waters had no effect on the concentrations of sodium, potassium, calcium, magnesium, or chloride in the blood plasma. Sulphate, however, was significantly higher, throughout a considerable portion of the experiment, in the plasma of the sheep which received either 0.30 or 0.50 per cent. sodium sulphate. None of the saline solutions used in the experiment had any adverse effect on the general health, food consumption, weight increase, or wool production of the sheep.

One group was offered rain-water to drink, another group was offered 1.30% sodium chloride, whereas the others were offered one of the following mixtures of sodium chloride, carbonate, and bicarbonate: 1.26 + 0.015 + 0.025, 1.21 + 0.04 + 0.06, 1.12 + 0.08 + 0.13, and 0.95 + 0.161+ 0.25%. The intake of all saline solutions was higher than that of rain-water, ranging from 150% above for 1.30% sodium chloride to 60% above for the highest level of carbonates; the mean daily intakes for the entire experiment by the six groups were 2.6, 6.6, 4.8, 5.7, 5.8, and 4.2 l. respectively. The intake also increased in all groups with temperature, being 40–70% higher in the hottest months than in the coldest months.Weight increase was less from 6 months onward in the group receiving 1.30% sodium chloride, and was less at certain times only in the experiment in the groups receiving 0.04 or 0.10% carbonates, than in that receiving rain-water (control group). There were no differences in weight increase between the control group and the groups receiving the highest concentrations (0.21 and 0.41%) of carbonates The saline drinking waters had no effect on the concentrations of sodium, potassium, calcium, magnesium, or chloride in the blood plasma. The concentration of carbon dioxide was higher, for the last year of the experiment, in the blood of the control group, and, for approximately one-third of the experiment, in that of the group receiving the highest level of carbonates in its drinking water, than in that of any of the groups receiving lower levels of carbonates. There were differences in blood carbon dioxide on one occasion only between the control group and that receiving the highest level of carbonates. None of the solutions used in the experiment had any adverse effect on the general health, food consumption or wool production of the sheep.

Seven groups, each of six sheep, were fed in pens for 16 months on a ration of chaffed lucerne and wheaten hays. One group was offered rain-water to drink, another group was offered 1.30 per cent. sodium chloride, whereas the others were offered one of the following mixtures of sodium and magnesium chlorides : 1.27 + 0.02, 1.24 + 0.05, 1.18 + 0.10, 1.05 + 0.20, and 0.69 + 0.50 per cent. Many of the animals refused to eat or drink satisfactorily when the saline waters were first offered. If, however, the concentrations were increased gradually over a period of 3 weeks to the desired levels, satisfactory performance by most animals was obtained. The intake of water containing 1.30 per cent. sodium chloride was higher than that of rain-water, and the intake increased with increasing concentrations of magnesium chloride up to 0.10 per cent.; the mean daily intakes for the entire experiment by the seven groups were 2.3, 3.9, 4.2, 4.8, 5.0, 4.3, and 3.5 1. respectively. The intake also increased in all groups with temperature, being 60-100 per cent. higher in the hottest months than in the coldest months. A concentration of 1.3 per cent. sodium chloride, and concentrations of up to 0.10 per cent,. magnesium chloride with 1.2 to 1.3 per cent. sodium chloride, had no adverse effect on the sheep, but 0.20 or 0.50 per cent. magnesium chloride (with 1.05 and 0.69 per cent. sodium chloride respectively) was detrimental to some of the sheep. The principal effect was a reduction in food consumption. The only other obvious sign in these last two groups was an occasional diarrhoea; this was more frequent on the higher concentration of magnesium chloride. The saline drinking waters had no effect on the concentrations of sodium, potassium, calcium, or chloride in the blood plasma. Magnesium, however, was significantly higher, throughout most of the experiment, in the plasma of the sheep which received 0.50 per cent. magnesium chloride.

Seven groups, each of six wether sheep, were fed in pens for 15 months on a ration of chaffed lucerne and wheaten hays and were offered various solutions as drinking waters. These comprised: (1) rain-water (control group); (2) 1.30% sodium chloride; (3) and (4) synthetic waters containing salts in the proportions found in many underground waters in South and Western Australia (referred to in this paper as "chloride waters"), with total concentrations of 0.65 and 1.30% respectively; (5) and (6) synthetic waters resembling those obtained in Queensland from the Great Artesian Basin ("bicarbonate waters"), with total salt concentrations of 0.20 and 0.50% respectively; and (7) sea-water diluted with rain-water to a total salt concentration of 1.30%The intake of all saline solutions, except that of the bicarbonate water with a concentration of 0.20% salts, was higher than that of rain-water, the increases ranging from 80% for 1.30% sodium chloride to 15% for the more concentrated bicarbonate water. The intake also increased in all groups with temperature, being 40-90 % higher in the hottest months than in the coldest months.Compared with the control group a significant decrease in wool production was observed only in the group receiving bicarbonate water with 0.50% total salts. These sheep also produced significantly less wool, for at least a portion of the experiment, than did those receiving the other synthetic mixtures of salts.The concentrations of potassium, calcium, and chloride in the blood plasma were not affected by the saline drinking waters. The concentrations of sodium at times were higher in the plasma of the control group and lower in the plasma of group 2 (1.30% sodium chloride) than in that of the remaining groups. Magnesium concentrations at times were higher in group 7 (diluted sea-water) and lower in group 2 than in the remaining groups. None of the solutions used in the experiment had any adverse effect on general health, food consumption, or weight increase.

Four groups, each of six sheep, were fed in pens for 15 months on an adequate diet of chaffed lucerne and wheaten hays. One group was offered rain-water to drink, whereas the others were offered similar water to which sufficient sodium chloride had been added to give concentrations of 1.0, 1.5, or 2.0 per cent. sodium chloride. The intake of water increased with concentration of sodium chloride, the mean daily intakes for the entire experiment being 2.0, 3.0, 4.4, and 3.0 1. for the groups whose water contained 0, 1.0, 1.5, and 2.0 per cent. sodium chloride, respectively. It also increased in all groups with temperature, being 50-70 per cent. higher in the hottest months than in the coldest months. The intake of sodium chloride by some sheep was very high; four of them consumed over 115 g (0.25 lb) daily for more than half the experiment, and 170-230 g daily for periods of 1-10 weeks. A concentration of 1.0 per cent. sodium chloride in the drinking water had no adverse effects on the sheep, but 1.5 per cent. TI-as detrimental to a small proportion and 2.0 per cent. was detrimental to all of the sheep. There was a decline in food consumption and body weight of the affected ammals, and several receiving 2.0 per cent. sodium chloride became very emaciated and weak and two were killed in extrentis. The only other obvious sign was an occasional diarrhoea which occurred in most of the sheep receiving 2.0 per cent. sodium chloride. Sodium chloride in the drinking water had no effect on the concentration of sodium, potassium, calcium, or magnesium in the blood plasma. It did, however, affect the chloride concentration; this was significantly higher, throughout the experiment, in the group which received water containing 2.0 per cent. sodium chloride.

Intakes of twenty-four mineral elements were calculated applying the composition data from the Mineral Element Study (KOIVISTOINEN 1980) to the amounts of food consumed by 1607 Finnish children aged 5, 9 and 13 years (RÄSÄNEN and AHLSTRÖM 1975). The mean daily intakes of calcium, phosphorus, potassium, magnesium and manganese exceeded the recommended daily intakes in all age groups and that of iron in the 5- and 9-year-old groups. The intakes of zinc, copper, selenium, molybdenum, fluorine and chromium were lower than recommended in all age groups studied. The main sources of minerals were the food groups milk and milk products and cereals and cereal products, which supplied more than 50 per cent of the total intake of most mineral elements. The intakes of essential mineral elements would increase If the share of refined foods such as dietary fats, sugar and candy were to be decreased in the children s diet.

Water Borne

Five groups, each of six sheep, were fed in pens on an adequate diet of chaffed hay and crushed grain for 3½ years. One group was given rain-water to drink, whereas the others were offered similar water to which sufficient sodium fluoride had been added to give final concentrations of 2.5, 5, 10, or 20 p.p.m. F. The mean daily intakes of fluoride, expressed as fluorine, by the four experimental groups were approximately 5, 9, 18, and 37 mg. F respectively during the winter months and 7, 13, 27, and 53 mg. F respectively during the summer months. The ingestion of fluoride appeared to have no adverse effect on general health, food consumption, or wool production. The mean weights of all groups were approximately the same throughout the experiment except at the end of 2½ years, when the weight of the group which received water containing 20 p.p.m. F was significantly less, but only at the 5 per cent. level, than that of either the control group or the groups receiving the lowest two intakes of fluoride. Mottling of the incisors and molars was only slight among the sheep which received water containing 5 p.p.m. F. It was more evident in the 10-p.p.m. group and was marked in the 20-p.p.m. group. Selective abrasion of the molars was pronounced in this last group but was also noticeable in the 10-p.p.m. group. Fluoride intake caused the incisors to erupt at an earlier age. Ingestion of fluoride brought about increases of up to twentyfold in the fluoride content of the bones and teeth. The bearing of these results on enzootic dental fluorosis among grazing sheep in Queensland is discussed.
