| Abstract |
Eighty males and females weanling New Zealand White rabbits at five week old were used to evaluate the effect of substitution of dried whole Portulaca oleracea (Purslane) at the levels 0, 10, 20 and 30% on the expense of soybean meal as source of protein in rabbits diet on growth performance, digestibility of nutrients, carcass traits, some blood constituents, liver and kidney functions and immunity. The results indicated that final body weight, daily weight gain and growth rate were significantly higher by 12.57, 19.34 and 5.14 %, respectively. Daily feed intake was significantly increased from 102.75 to 117.30 g/ day when Portulaca oleracea (P.O.) induced in the diets at the level of 20 %. The best feed conversion was recorded by rabbits fed diet substituted with 20% P.O. Growing rabbits could be fed 20 % P.O, on the expense of soybean meal without any adverse effects and realize the best values of growth performance, digestibility coefficients, carcass traits, globulin level and immune response. Economical efficiency and the relative economical efficiency were also improved with such level of P.O.
Key words: rabbits, Portulaca oleracea, growth performance.
