Effect of exogenous glucoamylase enzymes and reduction of grain level on lamb performance Article uri icon

abstract

  • A growth assay was conducted to evaluate if the addition of exogenous glucoamylase enzymes from Aspergillus niger maycompensate the reduction of grain level in finishing diets for lambs. Twenty one Suffolk crossbred lambs (BW 16.6(±1.5 kg) were randomlyassigned to the following treatments: 72%25 grain; 60%25 grain%2bglucoamylase (0.12 g enzyme protein/kg grain) and; 60%25 grain. The average daily gain (kg), intake (kg/d) and were not affected bythe treatments. The best feed conversion was observed with 72%25 grain; however, partial feed efficiency(slope of regression between intake and average dailygain) was improved in diet with 60%25 grain plus enzyme. © 2011 Taylor %26 Francis.
