[State of acid-base balance in chickens and pigs in commercial livestock farms].

Experiments on chickens of different age groups (one day--1 months) from large poultry plants of the Kiev Region established that metabolic acidosis develops in chickens at the age of 10-30 days. Compensated alkalosis is observed in them at the age of two months and further. In chickens whose HCO3- level in blood is 15-18 mM/l the content of uric acid in the liver and blood increases as compared to the control (HCO3- --23 mM/l); they also differ in a high intensity of the growth. A rise of the HCO3- concentration in chicken blood up to 33 mM/l favours a still greater decrease in the level of uric acid in tissues and an increase in the chicken growth intensity as compared to the control. Studies in the state of the blood acid-base balance in pigs of the commercial complex "Kalityansky" showed that compensated alkalosis develops in the whole pig stock.
