Lactate metabolism by cardiac muscle and liver from Pietrain and Minnesota No. 1 pigs and their reciprocal crosses


, : Lactate metabolism by cardiac muscle and liver from Pietrain and Minnesota No. 1 pigs and their reciprocal crosses. Journal of Animal Science 43(6): 1211-1217

The intrinsic capacity of heart and liver to utilize lactate in porcine breeds of varying degrees of stress-susceptibility was studied. Experimental animals were stress susceptible Pietrain barrows (P .times. P), stress resistant Minnesota No. 1 barrows (M .times. M) and barrows from reciprocal crosses of these breeds (P .times. M and M .times. P). Parameters of postmortem muscle quality generally characterized P .times. M pigs as exhibiting values intermediate between the pale, soft, exudative musculature of P .times. P pigs and the normal morphology of the M .times. M breed. Muscle quality in M .times. P pigs tended to be close to M .times. M pigs. No significant differences were noted for the capacity of cardiac muscle to convert lactate to CO2 expressed as micromoles CO2 per gram per hour, or on a total heart weight basis. CO2 production from lactate by liver expressed as micromoles CO2 per gram liver per hour was higher (P < .05) in P .times. P than M .times. P and P .times. M but not significantly different from M .times. M; M .times. M exceeded (P < .05) M .times. P. Expressed as micromoles CO2 per total liver per hour, P .times. P pigs exceeded P .times. M and M .times. P (P < .05) but were not significantly greater than M .times. M. Lactic acidosis during the stress syndrome is apparently not related to deficient hepatic or cardiac utilization of lactate since the stress susceptible P .times. P pigs ranked high in both characteristics.
