The food intake and growth rate of broilers kept at high temperatures can be improved by supplementing the diet or the drinking water with sodium bicarbonate. The response appears to be due to the bicarbonate ion and is associated with an increase in water consumption. Measurements of dietary or retained values for cation–anion balance or dietary electrolyte balance were unsatisfactory for predicting the growth and/or feed conversion responses of broilers at high temperatures. Improvements in body weight do not appear to be associated with increased body water retention.
Dietary inclusion of different levels of NaHCO3 depicted a signific
ant increase in antibody titter against Newcastle disease in layers when compared to those fed diet without its addition. Environmental stressors have been known to affect immunity and innate resistance of the host directly or indirectly. Therefore, increase in antibody titter against Newcastle disease virus in birds fed diets containing different levels of NaHCO3 may probably be due either to less heat stress upon these birds because of reduction in their body temperature or lower cortisol concentration as compared to those of control group, or both.
An increase in dietary electrolyte balance may cause a decrease in heterophil to lymphocyte ratio in blood, leading to an increase in antibody titter. Similarly, a significant linear increase in Newcastle disease virus antibody titters with increasing DEB (40, 140, 240, 340mEq/kg), using NaCl, NaHCO3 and NH4Cl as supplements, Therefore, it may safely be concluded that the dietary addition of NaHCO3 may improve antibody titter against Newcastle disease virus in layers.
The addition of NaHCO3 in the diet of layers exhibited more digestibility of protein in these birds as compared to those of the control group. Protein consumed by the birds is broken down by the action of certain enzymes in the gastrointestinal tract to its constituent amino acids prior to absorption, and most of these amino acids require sodium for this process. Therefore, the increase in digestibility of protein of the treated groups may probably be due to the presence of more sodium ions concentration in the rations containing sodium bicarbonate. Sodium containing compounds such as sodium bentonite has been successfully used in sorghum containing diets to prevent deleterious effects of tannins present in it, on digestibility of protein.
DESCRIPTION OF PROBLEM Sodium bicarbonate (NaHC03), also called baking soda, contains 27.09% sodium, 71.91% bicarbonate, and no chloride. It is an FDA-approved (Code of Federal Regulations, Title 21, 582.1736) and “generally recognized as safe” feed ingredient. Sodium bicarbonate has been characterised as a “privileged ingredient because it provides sodium, favourably affects blood pH, and supplies beneficial bicarbonate. Sodium in sodium bicarbonate was equally bioavailable to that in salt for broiler chicks. Chloride levels can be reduced during feed formulation by partial replacement of salt with sodium bicarbonate on approximately a 1:lS ratio by weight.
