The aim of this study was to evaluate the influence of supplying water with varying salinity levels to dairy goats on nutrient intake, apparent nutrient digestibility, and milk yield. The experiment lasted 65 days and involved 24 crossbred goats with mean body weight of 38±4 kg, which were randomly allotted. It was set in a completely randomized design with four treatments consisting of 640, 3188, 5740 and 8326 mg L?1 total dissolved solids (TDS) in the drinking water. The results showed that water salinity levels had no effect on the intake of dry matter, neutral detergent fiber, crude protein, ether extract, total carbohydrates, non-fibrous carbohydrates, total digestible nutrients, metabolizable energy, digestible energy, or apparent nutrient digestibility. Water intake was influenced by the salinity, increasing as the salt level was increased. Moreover, the varying salinity had no significant effect on milk yield. Drinking water containing up to 8326 mg L?1 TDS provided no inter...
Influence of saltwater intake on the health of dairy cattle
Journal of Environmental Analysis and Progress
Water is an element extremely important, essential for life, and necessary to maintain some factors such as intracellular pressure, assist digestive processes, carry nutrients, eliminate toxins through urine and allow the thermal balance of living things. However, it is a scarce element as the national water resources policy in Brazil advocates. In recent years water has become one of the biggest global problems due to lack and quality. The objective of this study was to evaluate the influence of saline intake on the health of dairy cattle. The actions consisted of periodic visits to a rural property located in the city of Pesqueira, Agreste Pernambucano - Brazil, whose main economic activity is milk production and cheese making. The herd has milk aptitude and consists of 182 animals. Samples of desalination tailings water that were supplied for quench the animals were collected. Blood samples from the cattle were collected and sent for hematological exams. The results showed altera...

S hortage of feed resources and salinity of water are common characteristics in marginal regions of desert areas and it is considered the main constraints to improve livestock productivity. The use of alternative feed resources from salt tolerant plants was proved to be useful in these regions (El-Shaer, 2006; 2010; Fayed et al., 2010). However, high salt intakes through feed stuffs or water decrease ruminant's productivity. Nevertheless, small ruminants could cope against these harsh conditions. Martin-Gronert (2006) found that adaptive responses such as alternation in water intake and hormonal changes could adapt pregnant ewes to a high dietary salt intake. He added that when high salt intake comes from feed alone, and there is an unlimited supply of freshwater, the animal can cope by increasing water intake and therefore increasing the salt excreting capacity by the kidneys. In pregnant ewes, Digby et al. (2008) found that the consumption of a 13% NaCl diet causes a decrease in aldosterone concentration reached research Article Abstract | This study aimed at investigating the effect of drinking saline water and feeding salt tolerant plant on some physiological parameters of pregnant Shami goats and their offspring. Forty late pregnant goats (at 4 th and 5 th months of pregnancy) were randomly divided into 2 groups (20 each). The 1 st group (control; C) was fed a diet consisted of concentrate feed mixture (CFM) plus berseem hay and drank fresh tap water (274 ppm TDS). The 2 nd group (S) was fed CFM plus Alfalfa and drank saline water (6000 ppm TDS). The treatment lasted to the weaning of their kids at 90 days of age. Body weight gain was significantly lower in females of S group than in control ones. Similar trend was observed in kids body weight gain from birth tell weaning. Total plasma proteins of pregnant Shami does were not affected by salt intake, but decreased with advancing pregnancy in females of the two experimental groups. Kids of S group had higher (P<0.05) levels of all plasma proteins than found in kids of C group. Total lipids and insulin decreased (P<0.05) by salt intake in pregnant goats and their kids. Leptin decreased (P<0.05) in pregnant does of S group but not in their kids. Liver and kidney functions indicators significantly increased in both does and their kids of group S. Blood electrolytes (Na and K) and plasma osmolality increased significantly in does drank saline water and their kids which have negative feedback on aldosterone. In conclusion, Shami goats can tolerate a high salt intake and living under harsh condition of marginal regions with minimum weight loss. Their offspring will be programmed to alter their adaptive response to grow well under these harsh conditions.

The present trials dealt with the combined effectof water salinityand infrequent water intake, onceevery72 hours, in two groups of rams fed roughagediets at the maintenance levelof digested protein intake, compared with sheep offered fresh tap water daily as controls. The results indicated that daily watered sheep responded favourably to drinking saline well water in terms of performance and weight gain, as well as nitrogen and mineral balances. Intermittent saline water intake, on the other hand, seemed to affect all characteristics studied adversely. The animals lost weight, digestive capacity was reduced and, therefore, DOM and DCP intakes decreasedsignificantly. Nitrogen and sodium balancesbecame negative, and the other mineral balances were also adversely affected. Further experiments are needed, particularly to re-evaluate established tolerance levels (I' 3% NaCI) which may differ according to types of salts in the well water and also under conditions of long adaptation to water deprivation.

The study aimed to investigate the effects of slightly saline (3000 ppm NaCl), moderately saline water (6000 and 9000 ppm NaCl), and highly saline water (12000 and 15000 ppm NaCl) on growing bovine native heifers during hot summer season of Egypt. Total and daily gain in heifers drank slightly saline water was significantly higher than those in heifers drank River Nile water (RNW). The gain of heifers drank moderately or highly saline water decreased significantly when compared with the gain of heifers drank RNW only. Total water intake (TWI) of heifers in heifers drank slightly or moderately saline water increased significantly, while TWI of heifers drank highly saline water decreased significantly when compared with the WI of heifers drank RNW. Dry matter intake (DMI) increased significantly in heifers drank slightly saline water, while DMI of heifers drank moderately or highly saline water decreased significantly when compared with DMI of heifers drank RNW. Drinking water contain...
Effect of short-term mild salinity stress on physiological and hematological parameters in sheep
Biologia, 2021
Contamination of water through salinization will affect the well-being of livestock. Therefore, it is necessary to understand how animals respond to increasing levels of salts in their water supply. This short communication describes the effects of a two-week salinity stress (0, 6, 12 g L − 1 NaCl) on Pelibuey sheep. The parameters measured in response to salinity stress were animal weight, rectal temperature, and levels of hemoglobin, hematocrits, lymphocytes, neutrophils, leukocytes and proteins. Specific activities of superoxide dismutase (SOD) and catalase (CAT) in blood samples were also recorded. The results showed that the 6 g L − 1 NaCl treatment resulted in the significantly highest body weight. There were no significant differences in the rectal temperature of animals. In terms of the hematological parameters, animals exposed to 6 g L − 1 NaCl displayed the significantly highest hemoglobin and hematocrit contents. There appeared to be no effect of consumption of saline water on the amount of lymphocytes, neutrophils, leukocytes or proteins. It was found that animals that consumed 12 g L − 1 NaCl supplemented water had the lowest levels of SOD activity. There were no significant differences in CAT specific activities in animals exposed to the saline water or the control. This is the first report on the response of Pelibuey sheep to short-term saline stress under Cuban environmental conditions.

Consuming saline water causes animals salinity stress, which leads to many adapting metabolic changes that could negatively affect its performance and the quality of the derived products. Therefore, this study aimed to evaluate the impact of increasing diet protein level on the productive performance of growing lambs drinking natural saline water in Egyptian semi-arid region. Twenty-four growing Barki lambs (4-5 months old) with an initial body weight of 20.7 ± 0.25 kg were randomly distributed into four similar groups for 150 days. Two diets were formulated: low protein and high protein levels (concentrate feed mixture containing 14% and 20% crude protein (CP) on dry matter basis, respectively). Within each level of CP, natural saline water was represented by low saline (LS) and high saline (HS) water, containing 658 and 2100 mg/L of total dissolved solids, respectively. Results showed that the HS water increased (p = 0.02) water intake by about 18% and had adverse effect (p < 0.001) on dry matter intake, nutrient digestibility, and growth performance. The ruminal pH values, total volatile fatty acids, and ammonia-N concentrations were not affected by drinking the HS water. However, the protein supplementation enhanced the HS lambs' nutrients digestion and showed greater growth performance. The HS water decreased (p < 0.001) the serum concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and increased (p = 0.03) the urea-N by about 9%. The protein supplementation amended the serum ALT and AST concentrations of HS lambs. It is concluded that the dietary protein supply was affective sustainable management strategy against the deleterious effect of drinking high saline water on growing lambs.

Background and Aim: The high salinity of drinking water has been a significant problem of the Mekong Rivers Delta. Animals drinking high salinity water altered feed and water intake (WI), urinary electrolytes excretion, and productivity. This study aimed to evaluate the effects of high salinity in drinking water on drinking and eating behaviors and kidney function in crossbred goats. Materials and Methods: The experiment was completely randomized with two treatments: freshwater (0%, seawater [SW0]) and water high in salinity (1.5%, SW1.5) from diluted SW, with five replicates (five animals per treatment). This experiment lasted 3 weeks: the 1st week for the pre-treatment period and the 2nd-3rd weeks for the post-treatment. Dry matter intake (DMI) and WI were recorded every day, while urine volume (UV) was determined from day 8 to day 21. Blood and urinary samples were collected on days 6, 14, and 21 of the study for electrolytes and creatinine analysis. Results: The results demonstrated that both DMI and WI were affected by SW1.5 (p<0.05). Goats drinking from SW1.5 had lower DMI during D19–21, and the ratio of DMI/WI was significantly different during D16–21 (p<0.05). Interestingly, the UV from SW1.5 was higher than that from SW0 during D13–21 (p<0.05). Although the body weights (BW) of both groups were similar (p>0.05), the weight gain observed in the SW1.5 group tended to decrease (p=0.056) at the 2nd week. The concentration of electrolytes in blood did not differ between the groups (p>0.05). In contrast, the concentration and excretion of Na+ and Cl- in urine increased in SW1.5 goats at D14 (p<0.05), while creatinine levels in the blood remained normal (p>0.05). Conclusion: The study concluded that crossbred male goats can tolerate 1.5% saline water from diluted SW for 2 weeks. The high salinity in water influences drinking and eating behavior in growing goats. However, the adaptive mechanism by increasing urine output and reducing the reabsorption of Na+ and Cl- in the kidney is the key function and works faster than behavioral responses. The kidney apparently drives drinking behavior during high salinity water consumption.

The current study aimed to evaluate the effect of drinking salinity levels in Lake water on the growth performance, physiological, and blood constituents of Hararghe-highland lambs. A total of 28 lambs (average IBW of 18±1.18kg) were categorized into four levels of water salinity, namely freshwater (510mg/l TDS), lake Basaka water (LBW; 2600mg TDS/L); lake Basaka water plus 100% TDS of LBW; 5200mg TDS/L) and lake Basaka water plus 200% TDS of LBW; 7900mg TDS/L). The current results suggest that increased TDS levels in lake water increase the water intake of lambs while not affecting IBW, FBW, AWG, and FCR. Additionally, drinking saline lake with increasing TDS levels increased RT and RR and caused a signi cant (P<0.05) change in the concentrations of glucose, albumin, urea, triglycerides, sodium, AST, ALT, T3, and T4. Some hematological variables and biochemical constituents like creatinine, total protein, cholesterol, chlorides, potassium, magnesium, and calcium showed no signi cant (P>0.05) differences. In conclusion, Hararghehighland lambs from Ethiopia could tolerate lake Basaka water with a high salt level (7952mg/L TDS).
