Access To Water

Sheep were fed on diets containing 7.5, 11.25, and 15% added sodium chloride to simulate diets containing up to 100% saltbush (Atriplex spp.). When access to water was restricted to once daily, there was a reduction in food intake, the reduction being more severe with the more salty diets. When fed on the diet containing 15% added sodium chloride and when their access to water was restricted to once daily, Merino sheep drank 5.01 l/day and Border Leicester sheep 7.6 l/day. Food intakes differed in approximately the same proportion, and on a body weight basis (kg0.73) the Border Leicesters ate 22% more food than the Merinos. It is concluded that Merino sheep will need to drink more often than once daily when their water intake exceeds 5 l/sheep/day, and that this would occur when the saltbush intake reached 500–600 g/day.

Intake Water

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.

The Mean

Dry adult Merino ewes were fed at daily or weekly intervals on oat grain at levels which provided 4.0, 3.0, or 2.0 lb starch equivalent (S.E.) per sheep per week. The experimental periods were 223, 223, and 181 days respectively. Differences between the mean body weights of the ewes a t the three levels of feeding were highly significant (P < 0.001). Body weight varied only slightly and no losses occurred in ewes fed weekly at the rate of 4.0 lb S.E. per head. Ewes fed daily a t this level had a significantly greater mean body weight (P < 0.001) a t the conclusion of the 223-day experimental period. The addition of a sodium chloride supplement did not improve the body weight or wool production of ewes fed weekly a t the level of 4.0 lb S.E. The mean body weight of ewes fed at the levels of 3.0 or 2.0 lb S.E. per head declined over the first 12 and 18 respectively and thereafter remained relatively constant. There were no significant differences at these levels of feeding between groups fed daily and weekly in respect of body weight, wool production, or survival rates. Ewes fed a t the level of 4.0 lb S.E. grew significantly more wool than those given 3.0 lb S.E. (P < 0.001). Losses were negligible in all groups except those fed a t the level of 2.0 lb S.E. In these groups there were few deaths in the first 16 weeks, but in the subsequent 10 weeks losses totalled 17.1 per cent. Ewes fed a t the level of 2.0 lb S.E. consumed their rations at a significantly slower rate (P < 0.01) than did those fed a t the level of 4.0 lb S.E.

Increase Water Consumption

We recently reported that intracerebroventricular infusions of ANG II decreased food intake and increased energy expenditure in young rats. The aim of the present study was to determine if intracerebroventricular ANG II has similar effects in adult rats. The time course of the effect was also investigated with the idea that at earlier time points, a potential role for increased hypothalamic expression of corticotropin-releasing hormone (CRH) in the anorexia could be established. Finally, the contribution of ANG II-induced water drinking to the decrease in food intake was directly investigated. Rats received intracerebroventricular saline or ANG II using osmotic minipumps. Food intake, water intake, and body weight were measured daily. Experiments were terminated 2, 5, or 11 days after the beginning of the infusions. ANG II (∼ 32 ng·kg−1·min−1) produced a transient decrease in food intake that lasted for 4–5 days although body weight continued to be decreased for the entire experiment most likely due to increased energy expenditure as evidenced by increased uncoupling protein-1 mRNA expression in brown adipose tissue. At 11 and 5 days, the expression of CRH mRNA was decreased. At 2 days, CRH expression was not suppressed even though body weight was decreased. The decrease in food intake and body weight was identical whether or not rats were allowed to increase water consumption. These data suggest that in adult rats ANG II acts within the brain to affect food intake and energy expenditure in a manner that is not related to water intake.

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

Animal model development of alcohol administration in rats is of crucial importance as it gives indirect information to effects of alcohol in humans. An indirect assessment of this would be the biochemical and histological data that could arise from such experiments. 20 Male Wistar rats weighing (63.50±3.79 g), were divided into four groups (consisting 15 treated animals and 5 control animals) and administered with varying concentrations of ethanol (5% 15% and 40%) via intragastric intubation for a period of 28 days. Probic evaluations, liver biochemical enzymes and alteration in histology profile of gastrointestinal tract (GIT) and viscera organs (namely the liver, kidney, heart and lungs) were determined after experimental duration. At 40% ethanol administration, the rats showed biochemically significant decrease in serum gamma glutamyl transferase (GGT), serum aspartate (AST) and Alanine amino transferase (ALT) when compared to normal study while 5% and 15% ethanol administered rats were comparable with control values i.e. normal study. Probic evaluations such as body weight, water intake and food intake showed percentage decrease in 40% ethanol administrated rat when compared with controls. The photomicrographs of the 5% and 15% ethanol administered rats indicated mild damage in their histological profiles when compared to the normal study while there was more adverse damage occurring in the 40% ethanol administrated rats. Conclusion: From this study, serum aspartate (AST), gamma glutamyl transferase (GGT) and Alanine amino transferase (ALT), probic evaluation (body weight, food intake and water intake) coupled with histopathological investigation may be used as biomarker for the early diagnosis of ethanol toxicity in human beings.

Dark Portion

The lateral hypothalamus (LH) has a critical role in the control of feeding and drinking. Melanin-concentrating hormone (MCH) is an orexigenic peptidergic neurotransmitter produced primarily in the LH, and agouti-related protein (AgRP) is an orexigenic peptidergic neurotransmitter produced exclusively in the arcuate (ARC), an area that innervates the LH. We assessed drinking and eating after third ventricular (i3vt) administration of MCH and AgRP. MCH (2.5, 5, and 10 μg i3vt) significantly increased food as well as water intake over 4 h when administered during either the light or the dark portion of the day-night cycle. When MCH (5 μg) was administered to rats with access to water but no food, they drank significantly more water than when given the vehicle. AgRP (7 μg i3vt), on the other hand, increased water intake but only in proportion to food intake during the dark and the light, and water intake was not increased after i3vt AgRP in the absence of food. Hence, in contrast to AgRP, MCH elicits increased water intake independent of food intake. These results are consistent with historical data linking activity of the LH with water as well as food intake.

SUMMARYA re-examination of the results from 374 sheep used in previovis studies of calcium metabolism show there is a highly significant linear relationship between endogenous faecal loss of Oa and food intake, endogenous loss increasing by about 0·64 mg/day/kg body weight for each 1 g/day/kg body weight increase in food intake. This loss was unaltered by Ca intake or by pregnancy and lactation but was slightly higher in young animals than in adult animals given the same Ca intake on a body-weight basis. It is suggested that a variable factor for endogenous Ca loss, based upon some measure of level of feeding, should be introduced into rationing schemes.
