A factorial bioassay was made to evaluate 4 different levels of exogenous saponin (S); 0 mg (S<SUB>o</SUB>), 25 mg (S<SUB>1</SUB>), 50 mg (S<SUB>2</SUB>) and 75 mg (S<SUB>3</SUB>) per kg and also a combination (SC) of 50 mg saponin plus 50 mg L-carnitine (S<SUB>4</SUB>) per kg maize-soybean meal based basal diet during the late autumn. In all, 5 experimental diets being iso-nutritive (as per NRC, 1994 recommendation) but for variable in presence and contents of saponin and L-carnitine were prepared. 8-day old male broiler chicks (n=150, Starboro) were distributed randomly into 15 groups of 10 chicks in each housed in separate pen of littered floor. Three such groups received each of 5 test diets <I>ad libitum</I> as mash up to 8 weeks of age. The plenty of water was made available to all chicks during the experimental period. It was found that S<SUB>2</SUB> diet significantly improved body weight gain (BWG) during growing (8 days to 3 weeks) period when compared with S<SUB>0</SUB>, S<SUB>1</SUB>, S<SUB>3</SUB> and S<SUB>4</SUB>. Dietary S and SC had no significant (p>0.05) effect separately and jointly on feed efficiency, protein efficiency and performance index. But S<SUB>3</SUB> and S<SUB>4</SUB> diets reduced abdominal fat significantly (p<0.05), while only S<SUB>3</SUB> significantly (p<0.05) increased tastes weight. S and SC added all diets significantly (p<0.05) reduced liver, gizzard and thyroid size with little enlargement of spleen size compared to S<SUB>0</SUB> fed group. Finally, it was concluded that 75 mg (S<SUB>3</SUB>) per kg exogenous saponin could be used as feed additive in broiler diet to improve growth and carcass quality. |
