“…Balances of P, Cl, K, Na, Ca, and Mg are required for normal cellular metabolism and the maintenance of the physiological functions of the organs. However, neural-humoral regulation may affect the body fluids to ensure embryonic chicken health and prevent conditions that may result from fluid and electrolyte imbalances (Levy, et al, 1990;McLafferty, et al, 2014). In our study, the embryonic chickens infected with NIBV exhibited significant increases in the concentrations of Na and Cl at 3 dpi and significant increases in plasma K concentrations at 3 and 5 dpi.…”

To examine the relationship of impairments of the liver and kidney with viral load after nephropathogenic infectious bronchitis virus (NIBV) infection in embryonic chickens, 120 specific-pathogen-free Leghorn embryonated chicken eggs were randomly divided into two groups (infected and control), with three replicates per group and 20 eggs in each replicate. The eggs in the infected and control groups were challenged with 0.2 mL of 105.5 ELD50 NIBV and sterile saline solution, respectively. The embryonic chickens' plasma and liver and kidney tissues were collected at 1, 3, and 5 days post-inoculation (dpi), the liver and kidney functional parameters were quantified, and the tissue viral loads were determined with real-time PCR. The results showed that plasma potassium, sodium, chlorine, magnesium, calcium, and phosphorus levels were increased. The infected group exhibited significantly higher plasma uric acid, blood urea nitrogen, and creatinine levels than the control group at 3 dpi. The plasma concentrations of aspartate aminotransferase and alanine aminotransferase were significantly increased in the infected group. The total protein, albumin, and globulin levels in the infected group were significantly lower than those in the control group. The liver-kidney viral load in the infected group peaked at 3 dpi, at which time the kidney viral load was significantly higher than that of the liver. Our results indicated that NIBV infection caused liver and kidney damage in the embryonic chickens, and the results also demonstrated that the liver and kidney damage was strongly related to the tissue viral load following NIBV infection in embryonic chickens.

“…Renal filtration rate, in response to dehydration, may be indirectly measured through plasma creatinine concentration ( Levy et al, 1990 ). Plasma creatinine may be a potential indicator which allows for discernment between dehydration, as a result of the transport process, vs. dehydration sustained prior on-farm, due to the length of restriction required to cause a significant rise in its concentration.…”

“…Furthermore, a rise in plasma urea during periods of water shortage can be related to a marked decline in urea excretion by glomerular filtration as Levy has suggested in a study on young ostriches (Levy et al., 1990). However, tubular reabsorption of urea depends on hydration conditions, and a substantial amount of filtered urea is reabsorbed during dehydration in birds (Skadhauge, 1981).…”

“…During water deficiency, plasma urea and CRE levels are usually used to indirectly assess renal filtration as the values of these blood metabolites are known to be elevated during water insufficiency, thus pointing to a possible alteration in GFR (Levy et al., 1990). The obtained results of the present study regarding plasma urea response to water restriction in the two breeds are surprising: in the local breed, plasma urea increased; in the commercial group, plasma urea significantly decreased.…”

Forty-five Hisex commercial layers and forty-five local Saudi breed layers were used to compare and assess the effect of water restriction under hot conditions on blood constituents and immune response to Newcastle disease (ND) vaccine. The trial was divided into three periods: control (7 day), water restriction (14 day) and rehydration (7 day). During water restriction, layers from each breed were divided into three groups that received 0%, 20% and 40% restriction of drinking water relative to the control period. The immune response against ND was affected by breed; it also declined significantly with 40% water restriction 10 days post-restriction. Water restriction did not affect haematocrit value, plasma total protein, albumin, glucose or osmolality, which may not suggest a reduction in plasma volume. However, plasma creatinine increased in both breeds because of water restriction that remained elevated during rehydration. Water restriction increased plasma urea in the local group, while it decreased in the commercial group. Irrespective of rate of water restriction, it can be concluded that the two breeds can withstand up to 40% water restriction during high environmental temperature. However, the local breed may be superior in water conservation in relation to the commercial layers.
