Two hundred and forty Ross Broiler chicken were used in a completely randomized design to evaluate the apparent digestibility of Obatampa, a quality protein maize (QPM) and normal maize (NM) nutrients with respect to crude protein, crude fibre, ether extract, ash and nitrogen free extract, as well as total tract and Ileal amino acids. There were 4 dietary treatments, each having 3 replicates with 20 birds per replicate. Two pure diets each of NM and QPM were formulated, one each without synthetic lysine supplementation (T2 and T3 for NM and QPM respectively) and one each with synthetic lysine supplementation (T2 and T4 for NM and QPM respectively). The diets were fed to the birds for two weeks before feacal collections and dissecting for Ileal sampling. Apparent Digestibility of nutrients, fecal and Ileal amino acids were higher for normal maize diets without lysine supplementation. Supplementation of diets with synthetic lysine increased nutrient and amino acids digestibility for QPM. |

An experiment was conducted to study the replacement value of dusa (locally processed maize offal) for maize in the diets of pullets (9-20 weeks) and their subsequent early laying performance. Three hundred and seventy eight (378) eight weeks old egg type pullets of approximately equal weights were randomly allocated to seven dietary treatments with three replicates of 18 birds each. The seven dietary treatments composed of rations in which graded levels of dusa replaced maize up to 100% in diet seven. At the end of the experiment average feed consumption was significantly (p<0.05) lower for the control and it increased as the level of dusa increased in the diets. The final body weight of pullets was better for treatment four which contained equal proportion of maize and dusa in the diets. The cost (N*kg gain) was significantly (p<0.05) higher for the control diet and it decreased as the level of dusa increased in the diets. The subsequent performance of birds revealed that the weight of birds at first egg, 10% and at 50% egg production were better for treatment four. The weight of first egg and ages at first egg were better for the diets with higher level of maize. There were no significant differences (p>0.05) in ages at 10%, 50%, peak egg production, weight of eggs at peak production and cost (N*dozen egg) for all the treatments. There was a 39.03% savings in cost of production by using dusa in pullets diets. |

This study was conducted to evaluate the effects of Palm Kernel Meal (PKM) in diets supplemented with or without enzyme (Maxigarin®) as replacement for Maize in broiler diets. Four hundred and five day old Arbor acres broiler chickens were randomly allotted to nine isonitrogeneous diet where PKM was included in the diet at 10, 20, 30, and 40% levels. Four of the diets contain PKM without Maxigrain® while the other four contained PKM with Maxigrain® supplementation. The Maxigrain® was added to the already formulated diet (supplementation) at 0.01% to four of the nine diets. At the starter phase the final body weight, weight gain and average daily weight gain were significantly (P<0.001) higher in 10% and 20% PKM diets Maxigrain® supplementation compared to other treatments. Feed intake was significantly (P<0.001) higher in the control, 10% and 20% PKM diets with Maxigrain®. The feed : gain ratio was significantly (P<0.001) lower in the 10% PKM diet with Maxigrain® compared to all other treatments. All levels of PKM diets with Maxigrain® were significantly (P<0.001) lower than the corresponding levels without Maxigrain®. The feed cost/kg weight gain were significantly (P<0.001) lower in all PKM diets with and without Maxigrain® compared to the control. At the finisher phase, the final weight, weight gain and average daily weight gain were significantly (P<0.001) higher in the 10% and 20% PKM diets with Maxigrain® compared to all other treatments. Feed intake was significantly (P<0.001) higher in all PKM diets with and without Maxigrain® compared with the control. Feed : gain ratio and feed cost/kg weight gain (N) were significantly (P<0.001) lower in the control and all PKM diets with Maxigrain® supplementation compared to all PKM diets without Maxigrain®. The results indicate that Maxigrain® supplementation of PKM diets improved the utilization of PKM. Diets with 10 and 20% inclusion of PKM and Maxigrain® were better than the control maize based diets. The dressed weight, neck, liver, lungs, kidney, abdominal fat, pancrease, spleen and length of intestines were significantly (P<0.001) different across treatments. Similarly, the percentage weight of the breast, thigh, heart and the intestines were significantly (P<0.001) different across treatments with no particular trend established. The drumstick, wings, head and gizzard were significantly (P<0.05) different across treatments. No significant difference in the dressing percentage and the back across the treatments. |

A nutrient retention trial was conducted over a twenty four day period. Eighty one day old chicks of Arbor acres strain were randomly allotted to nine isonitrogeneous dietary treatments where PKM was included in the diet at 0,10,20,30 and 40% levels and PKM treated with Maxigrain® at 10, 20, 30, and 40% levels with three replicates and three birds each in metallic cages. Results show that there was significant (P<0.001) difference in protein, fat, NFE and metabolizable energy retention which were higher in the control and Maxigrain® treated diets compared with the corresponding diets without Maxigrain®. The crude fibre retention was significant (P<0.05) lower in the control compared treatments. The crude fibre retention values at 20 and 30% PKM diets with Maxigrain® were significantly (P<0.05) lower than values for 20 and 30% PKM diets without Maxigrain®. The results indicates that enzyme treatment of PKM increased the retention of vital nutrients and metabolizable energy. |

Three hundred and sixty days old Ross Broiler Chicks were used in a completely randomized design feeding trial to evaluate the benefits of replacing Normal Maize (NM) with Quality Protein Maize (QPM) (Obatampa variety) in Broiler diets. There were 6 treatments of 3 replicates each and each replicate had 20 chicks. Six diets were formulated in which the NM in diet was replaced by QPM at 0, 25, 50, 75 and 100% representing T1, T2, T3, T4 AND T5, respectively while T6 was normal maize base diet balanced for lysine. The appropriate diets were fed to the birds for 4 weeks in the starter phase and 4 weeks in the finisher phase. At the starter phase, there was gradual numerical increase in weight gain as QPM increased in the diet. T5 was significantly better than T1-T4 but T6 was the overall best performance. Feed consumption was similar for T1-T5 but significantly higher for T6. Feed/gain ratio improved as QPM increased in the diet (p<0.05). Dressing % and weights of organs expressed as % of live weight and body parts expressed as % of dressed weight were not different statistically (p>0.05). |

Quality protein maize (QPM) was used to substitute normal maize variety in intensive rabbit study in attempt to reduce the cost of production. Thirty-six weaner rabbits with age ranging between 6-8 weeks and weighing between 225-300g were assigned to six treatment groups in a completely randomized design; six rabbits per treatment were individually caged and fed. The ration involved a percent replacement of normal maize with Quality protein maize at 0, 25, 50, 75, 100 % levels of inclusion across the treatments. The control diet involves a 0% level of QPM supplemented with synthetic lysine. Water and feed was provided ad-libitum throughout the study period of 56 days. Feed intake, water consumption, weight gain and mortality were recorded. Results showed no significant difference (P > 0.05) in total feed intake, weight gain, feed efficiency, water consumption, mortality rate, feed cost/kg weight gain. However, there was significant difference (P < 0.001) in feed cost/kg feed across the treatments. Carcass characteristics showed significant difference (P < 0.05) with no established trends in live weight, length of small and large intestines, liver, legs and tail. There was no significant difference (P > 0.05) in carcass weight, dressing percentage, heart, shoulder, loin, thigh, lungs, kidneys, spleen and head. The results indicated that feeding QPM to rabbits without lysine supplementation could sustain rabbits without affecting their performance, health and reduced cost of production. |
