Thesis (MPhil)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: The study investigated the performance of broiler production III two enterprises
around Gaborone. The main emphasis was on performance and feed efficiency of four
major production parameters, which include feed intake (FI), age at slaughter, body
weight (BW) and feed conversion ratio (FeR). The averages for slaughter age, BW
(live weight), FI and FeR for the two enterprises combined were 39.6 days, 1.8 kg,
3.41 kglbird and 1.96, respectively. For the entire rearing period the average
performance efficiency factor for the two enterprises was 224.
The results of the current study showed that age at slaughter, BW, cumulative FI,
FeR and mortality in the two farms declined significantly (P<O.OOI) over time. These
improvements in performance may be ascribable to the genetic improvements of the
broiler bird for fast growth, improved nutritional status as well as efficiency in
management on the part of producers. / AFRIKAANSE OPSOMMING: Die studie ondersoek die vordering van braaikuiken produksie in twee ondernemings
in die omgewing van Gabarone. Die klem was op die prestasie en voer
doeltreffendheid van vier groot produksie parameters. Die parameters sluit in;
voerinname (VI), ouderdom by slag, liggaamsmassa (LM), en voeromsettings
verhouding (VOV). Die gekombineerde gemiddeldes vir die twee ondernemings vir
slagouderdom, LM (lewende massa), VI en VOV was onderskeidelik 39.6 dae, 1.8 kg,
3.41 kg/voël en 1.96. Die gemiddelde prestasie doeltreffendheidsfaktor vir die twee
ondernemings, vir die hele groei periode, was 224.
Die resultate van die studie het daarop gedui dat ouderdom by slag, LM, kumulatiewe
VI, VOV en mortaliteite aansienlik afgeneem (P<O.OOI) het oor tyd. Hierdie
verbeteringe in vordering kan toegeskryf word aan die genetiese verbeteringe van die
braaikuiken voël vir vinnige groei, verbeterde voedingstatus, sowel as
doeltreffendheid in bestuur vanaf die produseerders.
