Email this article Effect of African nutmeg (monodora myristica) spice in aflatoxin-infected diets on growth performance of broilers
Abstract
Effect of toasted African Nutmeg (Monodora myristica) spice in Aspergillus flavus-infested diets on growth performance of broilers was investigated using broilers in a 3x2 factorial experiment. Infection status was significant (P<0.05) for daily weight gain, feed conversion ratio and protein efficiency ratio. Daily weight gain, feed conversion ratio and protein efficiency ratio were 134.19g/b/d, 39.23g/b/d, 3.59g/b/d and 1.10g/b/d for the non-infected diets, while aflatoxin infection from Aspergillus flavus was observed to reduce (P<0.05) feed intake to 130.51g/b/d and weight gain (33.67g/b/d). FCR and PER were also reduced (P<0.05) by the presence of aflatoxin from Aspergillus flavus in the diet. Effect of Monodora myristica supplementation on feed intake, average daily weight gain, FCR and Protein efficiency ratio was significant (P<0.05) for all the measured parameters. The Feed intake, average daily weight gain, FCR and Protein efficiency increased (P<0.05) as Monodora myristica inclusion level increased. Feed intake (119.8g/b/d), daily weight gain (28.90g/b/d), FCR (4.28) and PER (0.94) were observed in the Monodora-free (0%) diet. 0.5% and 1.0% levels of Monodora inclusion produced similar (P>0.05) effects on all the growth parameters but were higher than the control. The interaction of aflatoxin infection and Monodora inclusion level were significant for all the growth parameters. The interaction of aflatoxin infection x Monodora inclusion levels recorded feed intake of 107.97g/b/d, 137.36 and 146.19g/b/d respectively for 0%, 0.5% and 1.0% Monodora; 22.27g/b/d, 37.87g/b/d and 40.83g/b/d daily weight gain and 4.85%, 3.63% and 3.58% FCR. The interaction effect of Monodora inclusion level in infection-free diets on the birds feed intake were 131.65g/b/d, 147.24g/b/d and 123.67g/b/d respectively for 0%, 0.5% and 1.0%. The interaction effect at 0.5% inclusion level x non-infected diet was significantly higher (41.31g/b/d) than that at 0% inclusion level on daily gain. However, the daily weight gains of 40.83g/b/d observed in the interaction of 1.0% Monodora level x aflatoxin -free diet similar (P<0.05) to that observed in the 0.5% inclusion level. The feed conversion ratio produced by the interactions at the three different levels (0%, 0.5% and 1.0%) in the Aspergillus-free diets were (P>0.05) 3.71, 3.57 and 3.49 respectively while PER were (P<0.05) 1.05, 1.13 and 1.11 respectively. From the results, Monodora myristica tends to be a beneficial to poultry farmers, since about 90% of the poultry feed ingredients especially grains are constantly exposed to aflatoxin infection from Aspergillus flavus and other mycotoxin infections which hinder maximum nutrient utilization and affect the rate of conversion of feed.
