EFFECT OF DIFFERENT MANAGEMENTAL SYSTEMS ON CERTAIN BIOCHEMICAL ATTRIBUTES IN BLOOD AND MUSCLE OF BARBARI GOAT

摘要

The study was conducted under three managements! systems. One, the semi intensive system (G I), inwhich the animals were allowed to graze for 8 hours and diet supplemented with concentrate. Second, theintensive system (Gil), where the kids were stall-fed with concentrate and roughage ad lib. Third, theextensive system (Gill), in which the animals were allowed to graze for 8 hours and no concentrate wasgiven. Animals were slaughtered after 8 months of experimental period. Blood was collected and glucose,serum protein and its fractions were esiimated. Muscles were taken from rib, thigh and shoulder regions.Glycogen, CP, ATP, Pi and pH were measured in muscles. The effect of management system was assessedon blood glucose, total protein, protein fractions and muscle glycogen. The glucose, protein and globulinwere found more in G I and G II than in Gill. Albumin did not vary significantly between the systems. Muscleglycogen concentration was higher in Gil than Gl and lowest was recorded in Gill indicating that intensivesystem is better than other management systems. Similarly, higher glycogen contents were found in ribfollowed by thigh and lesser in shoulder muscles. Settling of rigor mortis was observed by estimatingbiochemical attributes of muscles. Glycogen exhaustion was fast within 1st 6 hours and progressivelydecreased thereafter in all groups and regions. Creatine phosphate was mostly exhausted within 6 hoursand became negligible at 12 hours. ATP concentration was more in Gil as compared to other groups,however, had the similar pattern of its utilization in all groups and regions. Inorganic phosphate concentrationwas highest in Gill as compared to Gl and Gil that got increased being hydrolyzed product of CP and ATP.Fall in pH values from 0-12 hours from 7.12 to 6.11 in all groups indicated better preservation of carcass.
