Assignment (MPhil)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: The study conducted was aiming on evaluating the influence of different levels of
energy and amino acids, mainly lysine and methionine, on production performance
of the layer bird. There were three treatments, namely the Control diet, a high
energy, lysine and methionine diet (High spec.) and a low energy, lysine and
methionine diet (Low spec.). The energy levels were 11.2 MJ/kg, 11.5 MJ/kg and
10.9 MJ/kg respectively. Lysine levels were 0.67%, 0.73% and 0.63% whereas
methionine levels were 0.36%, 0.38% and 0.34% respectively. The experimental
design was 3 x 4 factorial, which is 3 treatments with 4 replicates each. Results
showed no significant difference (P>0.05) between treatments in egg production,
egg mass, egg output, bodyweight and mortality. Feed intakes of the High spec. diet
were significantly lower (P<0.05) than that of the control diet and the Low spec. diet. / AFRIKAANSE OPSOMMING: Hierdie studiestuk handeloor die evaluering van die invloed wat die verskillende
vlakke van die energie en aminosure, veraiiisien en methionine op die produksie
van 'n lê hoender het. Daar was gebruik gemaak van drie behandelings, naamlik die
kontrole dieet, 'n hoë energie, lisien en methionien dieet (Hoë spesifikasie), en 'n lae
energie, lisien en methionien dieet (Lae spesifikasie). Die energievlakke was 11.2
MJ/kg, 11.5 MJ/kg en 10.9 MJ/kg onderskeidelik. Lisienvlakke was 0.67%, 0.73%
en 0.63% waarby methionienvlakke was 0.36%, 0.38% and 0.34% onderskeidelik.
Die eksperimentele ontwerp was 3 x 4 fakulteitsfunksies: 3 behandelings met 4
replikas elk. Die resultate het geen noemenswaardige verskille (P>0.05) tussen die
behandelinge in eierproduksie, eiergewig, eier-uitset, liggaamsgewig en mortaliteite
nie. Die voerinnames van die hoë spesifikasie dieet was aansienlik laer (P<0.05) as
die van die kontrole en lae spesifikasie dieet.
