【 摘 要 】

The aim of the research was to investigate the effect of diets containing Portulaca oleraceae (purslane) as a source of omega-3 fats on carcass and cut yields of broiler chickens. One-day old unsexed Lohmann broiler chickens (n = 180) were used and randomly allocated into 30 pens (each pen contained 6 birds). The pens were randomly assigned to five experimental diets with 6 replicates (36 birds per treatment). The diets were formulated by supplementing a basal diet with purslane meal at a level of 0, 1.5, 3.0, 4.5 and 6.0%. For a period of 42 days, water and diets were provided ad libitum. Feed intake and body weight gain were collected weekly to determine feed conversion ratio. The collected data were analysed using analysis of variance. If there were significant differences between treatment means, the analysis was continued by Duncan's New Multiple Range Test. Findings showed that diets enriched with omega-3 fats, alpha-linolenic acid did not change body weight and carcass percentage of broilers. In terms of cuts yield, there was no significant different on the percentage of breast, back and wings by feeding diets supplemented with purslane meal. However, the inclusion levels of dietary purslane meal significantly affected the percentage of thighs (P
