Abstract

An experiment was conducted at the Poultry unit of Kizimbani Agriculture Training Institute in Zanzibar to evaluate the effect of seaweed as mineral source in the carcass characteristic of broiler chickens. A one week chicks were assigned to their respective treatments (Sw0, Sw1, Sw1.5 and Sw2) and each treatment was replicated four times with fifteen (15) chicks in each replicate making total of (240 chicks) allocated to four dietary treatments with varying inclusion level of sea weeds (Sw0, Sw1, Sw1.5 and Sw2), containing 0, 1, 1.5 and 2% seaweeds, from 8 - 49 days of age.

Feed intake was measured daily while live weight was measured on a weekly basis. After seven weeks 2 chickens from each replicate were slaughtered to determine carcass yield and carcass characteristics. Proximate analysis of seaweed showed high ash content (47.65%) low levels of CP (5.42%) and CF (3.29%). Mineral analysis in see weed showed that it is rich in both macro and micro elements and low in amino acids. Body weight was significantly (P < 0.05) higher in Sw1.5 (2549.0g) and lower for Sw2 (2275.3g). Significant differences in carcass and non-carcass components were observed (P < 0.05). Final body weight was lower in Sw0 (2229.4g) and high in Sw1.5 (2481.9g). Carcass weight was highest in Sw1.5 (1961.3g) followed by Sw2 (1903.8g) and lowest in Sw0 (1673.8g) whereas dressing percentage was lowest in Sw0 (75%) and highest in Sw1.5 (79%). Dietary treatments had insignificant effect on overall lean, bone and fat weights. Dietary treatments had no effect on meat tenderness. Similarly, dietary treatment had no significant effect on tissue distribution apart from the bone in the drumstick. It is included that Seaweed inclusion at 1.5% (Sw1.5) had overall positive effect on all dependent variables hence dietary treatments which contained 1.5% can be considered as optimum in broiler diets.
