Lambs artificially reared were given either no salt supplement (LS lambs) or 2.0 g NaCl supplementation (kg body weight)-1 (HS lambs) by oral route from an early age. The food intake, water intake, urine output, growth rate and wool production were measured for several months to identify any changes in the performance of the lambs. Growth rate of HS lambs, although relatively high, was significantly less (P < 0.001) than in LS lambs, owing mainly to HS lambs having a reduced food intake. Linear relationships between water and food intakes were maintained, but shifted to a new plane for the HS lambs. The high intake of NaCl caused water intake to increase, which appeared to be mostly used to excrete the NaCl through increased urine output. Lambs given a high intake of NaCl had a lower food intake, but the reasons for the reduction could not be defined in this experiment. Wool production was reduced, but not significantly, by a high intake of NaCl. Diarrhoea was observed on more than one occasion in HS lambs during the experimental period.

This study examined the effects of selected groups of essential amino acids (EAAs), given by gavage, on short-term food and water intake. Amino acid groups were selected on the basis of their common physiologic functions in relation to current hypotheses on the role of amino acids in food intake control, and the quantities given were based on the proportions in 1.5 g of the EAA content of albumin. The complete EAA mixture (1.5 g) suppressed food intake by an average of 60 and 37% during the 1st and 2nd h of feeding, respectively, but had no influence on feeding in the subsequent 12 h. Total daily (14 h) intake was decreased by 9%. With the exception of the aromatic amino acid (Phe + Tyr + Trp, 0.34 g) group, all groups significantly decreased food intake by a comparable magnitude (32%) during the 1st h. In this time period, rats given the EAAs, Arg + Met + Val (0.38 g), and Arg + His + Lys (0.44 g) mixtures increased their water intake, whereas intake by rats given the Phe + Tyr + Trp + Thr (0.46 g) and Ile + Leu + Val (0.45 g) mixtures was unchanged. Thus, the food intake suppression caused by EAAs was not accounted for by an equal effect of its component amino acid groups. As well, food intake suppression by amino acid groups was not explained by increased water consumption, nor was it simply related to the quantity of nitrogen provided by the treatment.Key words: food intake, water intake, essential amino acids.

Eighteen rats were divided into three equal groups. The first group was closed orally with quassin, the second group was dosed with quassin after the gut flora were suppressed by difierent antibiotics, and the third group was served as a control. Food intake, water intake, and change in body weight were measured daily before dosing, during two weeks of dosing, and during one week after stopping dosing. Two eats from each group were killed at the end of each week, and stomach, liver, and kidney were collected for histopathologic examination. The results show a significant decline in daily food intake and daily change in body weight, and a significant increase in daily water intake in both dosed groups during the dosing period. Microscopic lesions were seen in the kidneys of both dosed rats group killed at the end of first and second week

Exposure of rats to air at 6 °C for 10 days increased food intake and urine output but failed to affect water intake. A comparison of water with food intake revealed a smaller water intake for a given food intake for cold-exposed than for control rats. The urine output at a given water intake was also greater for cold-exposed rats. In addition, cold exposure failed to affect urine osmolality significantly. Thus, the greater solute output accompanying cold exposure was accomplished by increasing urine flow rather than by concentrating urine. These results suggest possible mechanisms for both the relative dehydration and increased plasma osmolality observed after removal of rats from cold air. Both fecal and urinary routes of sodium and potassium excretion were increased by cold exposure; however, fecal excretions of both potassium and sodium were greater fractions of the total output during cold exposure than prior to it. Although cold exposure tends to induce a relative dehydration in rats, an important factor limiting the extent of the dehydration may be increased fecal electrolyte loss.

Sodium chloride was added in different amounts to the diet or drinking water of Merino sheep. The food intake declined at the higher concentrations (10–20% in food, 1.5–2.0% in water) but the decline was not related solely to the amount of sodium chloride ingested. The water intake increased in relation to the amount of sodium chloride ingested, irrespective of diet or means of ingestion (food or water). It is suggested that the acceptability or taste of food or water containing high levels of salt is a factor in determining the salt tolerance of sheep. The salt intake–water intake relationship is used to estimate the possible saving of fresh water to be derived from diluting it with saline bore water.
