Natural Growth Promoter

A 42 day feeding trial involving twenty five, seven
weeks old male grass cutters with an initial weight of 604.9 – 609.7g was
conducted to determine the growth response and carcass characteristics of
weaner grass cutters fed diets supplemented with P. longifolia seed oil as a natural growth promoter. Five diets
were formulated to contain basal diet + 0% P.longifolia
oil and Oxytetracycline for T1 this served as negative control while T2 was fed
basal diet containing Oxyteteracycline (synthetic growth promoter) as positive
control at 25mg/kg, T3, T4 and T5 were fed basal diet supplemented with P. longifolia oil as natural growth
promoter at 0.2%, 0.3% and 0.4% respectively. The grass cutters were randomly
divided into five groups of five grass cutters each with each grass cutters
serving as replicate in a completely randomized design experiment. Feed and
clean water were provided ad libitum. There was a significant (P<0.05)
differences among the treatments for final live weight, feed conversion ratio,
carcass weight and dressing percentage. There was no significant differences
(P>0.05) in mortality, feed intake, daily water intake, feed cost per kg and
relative weights of the organs examined ( liver, kidney, heart, spleen, testis,
intestine and abdominal fat). The result of this study indicates that the
inclusion of P. longifolia oil up to
0.40% has no deleterious effect on the performance and health status of grass


Keywords: Polyalthia longifolia
