Growth performance, economic benefits and sensory characteristics of meat from broilers finished on Acacia anguistissima leaf meal-based diets

摘要

The objective of the study was to determine growth performance, viscera organ development, economic benefit and sensory characteristics of meat from broilers finished on Acacia anguistissima leaf meal-based diets. One hundred and eighty Cobb 500-day-old chicks were used in the study. Acacia anguistissima was used as a protein source and included in broiler diets at 0, 50 and 100g/kg. Total feed intake (TFI), average daily gain (ADG), and gain to feed ratio (G:F) and cost benefit analysis were determined. There were no differences in TFI of broilers across treatments diets. Average daily gain and gain to feed (G:F) ratio were low (P&0.05) for broilers feeding on diet with100g/kg acacia meal. Highest returns from weight gain were obtained from broiler chickens fed on diet with 50g/kg inclusion level of A. anguistissima (P&0.05). Intestinal length increased with inclusion level of A. anguistissima whereas liver and spleen weight decreased with inclusion level of A. anguistissima (P&0.05). Female consumers gave higher scores for overall flavour intensity than male consumers (P&0.05). Treatment diets influenced consumer sensory characteristics of broiler meat (P&0.05). High sensory scores were observed for overall flavour intensity (OFI) for both boiled and deep fried meat from broilers fed 100g/kg A. anguistissima. It can be concluded that A. anguistissima meal can be used effectively up to 50g/kg in broiler diets without compromising performance of chickens and can influence a few sensory characteristics.
