摘      要：Whereas the use of probiotics is commonplace in commercial production of improved chicken strains,little is known about the impact of these live microbial feed additives in indigenous chickens in South Africa. This study investigated the effect of a multi-strain probiotic(containing Bacillus safensis, Bacillus subtilis, Bacillus megaterium and Cupriavidus metallidurans, total bacteria number was 1.4 × 10~8 cfu/mL),administered via drinking water, on growth performance, blood parameters, and carcass and meat quality characteristics of Potchefstroom koekoek cockerels for a period of 12 weeks. A total of 140 fiveweek-old cockerels were randomly allocated to 4 experimental diets formulated to have similar energy and protein levels as follows: 1) negative control diet(CON;commercial chicken grower diet without both antibiotics and probiotics), 2) positive control diet(ANTIB;commercial chicken grower diet with antibiotics [0.05% Coxistac and 0.04% olaquindox] but no probiotics), 3) negative control diet plus 2.5 mL of probiotics per litre of water(PROB25) and 4) negative control with 5.0 mL of probiotics per litre of water(PROB50). There was a significant(P 0.05) effect on overall feed intake, overall weight gain and haemato-biochemical parameters of cockerels. Gizzard and spleen weights were similar(P 0.05) in PROB50, CON and PROB25 groups. Cockerels in PROB50 group had shorter(P 0.05) small intestine than those in CON and PROB25 groups. Cockerels in PROB50 group had larger(P 0.05) breast weight than those in PROB25 *** in ANTIB and PROB50 groups had greater(P 0.05) wing and thigh weight
