  A study was conducted to determine the response of broiler starter and finisher chicks to dietary levels of Lablab purpureus beans processed by boiling in water for 30 min at 100 °C. For both the starter and the finisher phases, seven isonitrogenous diets containing 23.78% crude protein for the starter and 20.91% crude protein for the finisher were formulated to contain lablab seed meal at 0.0, 5.0, 10.0, 15.0, 20.0, 25.0 and 30.0% levels respectively. Diet 1, in each phase had no lablab and served as the control. Each dietary treatment for the starter and the finisher phases was replicated three times in a completely randomized design. There were 25 birds per replicate. Feed and water were given ad libitum. The experiment lasted from 0 to 4 weeks for the starter phase and from 5 to 8 weeks for the finisher phase. Results obtained for the starter phase shows significant (p<0.05) depression in final weight, weight gain, feed intake, feed efficiency and feed-gain ratio. These parameters decreased as the level of lablab seeds in the diets increased. However, feed cost (/kg feed and /bird) were significantly (p<0.05) reduced as the level of lablab seed meal increased in the starter diets. The results obtained for the finisher phase also showed a similar trend. While there were significant (p<0.05) decreases in final weight, weight gain, feed intake and feed efficiency as the level of lablab seed meal increased in the diets, feed cost (/kg feed and /bird) were significantly (p<0.05) lowered. Parameters measured for carcass analysis such as live weight and weights of the breast, thigh, wing, neck, legs and head showed a significant (p<0.05) decrease as the dietary levels of lablab seed meal increased. The PCV, Hb and the TP status of the blood indicated significant (p<0.05) decreases as the levels of lablab in the diets increased. However, Lablab purpureus beans can be included up to 5% level in broiler starter and up to 10% level in broiler finisher diets without any adverse effect on the performance of the birds.

  This study was conducted to determine the response of laying hens to graded dietary levels of cooked Lablab purpureus beans. Six isonitrogenous diets with similar calorie levels were formulated to contain lablab seed meal at 0.0, 7.5, 15.0, 22.5, 30.0 and 37.5%, respectively. Diet 1, which contained no lablab, served as the control diet. It was a normal groundnut cake-maize based layers ration. Each treatment was replicated three times in a completely randomized design. There were 25 laying hens per replicate. Feed and water were provided ad libitum. The birds were managed under the deep litter system. The experiment lasted for 6 months. There was a significant (p>0.05) decrease in final weight, percent change in body weight, feed intake (g bird-1 day-1), feed efficiency, percent hen-day and hen-housed egg production, percent production at peak, average egg weight (g) and income above feed expenses (x) as the level of lablab beans in the diets increased but feed cost (x/12 eggs), age at 25, 50 and at peak egg production (days) and the Roche Yolk Colour Fan (RYCF) score increased significantly (p<0.05) as dietary level of lablab seeds increased. It was concluded that lablab seed meal can be fed up to 7.5% dietary level in layers ration without any significant (p>0.05) adverse effect on percent hen-day and hen-housed egg production.

  This study was conducted to determine the effect of duration of cooking of Lablab purpureus beans on the performance, carcass characteristics and haematological profile of broiler finishers from 4-8 weeks of age. Seven isonitrogenous and isocaloric diets were formulated to contain 50% of Lablab beans boiled at 100OC for 0.0, 10.0, 20.0, 30.0, 40.0, 50.0 and 60.0 min, respectively together with a control diet which was a conventional groundnut cake-maize based broiler finisher diet. This amounted to a total of eight dietary treatments. Each treatment was replicated three times, in a complete randomized design. There were 25 broiler chicks (4 weeks old) per replicate. Feed and water were given ad libitum. The experiment lasted for four weeks. Results obtained show that increasing the duration of cooking of lablab seeds up to 30 min had significant (p<0.05) positive effect on final weight, weight gain, feed intake, feed efficiency and mortality rate. The performance of the birds became better as the duration of cooking increased up to 30 min. Beyond that, performance began to decline as the cooking time increased beyond 30 min. It was observed that birds fed the control diet performed significantly (p<0.05) better than all the lablab based diets.

  A total of 120 birds were divided into 5 groups of twenty four birds each. Each group was regarded as treatment. The treatment was subdivided into 3 groups of 8 birds each as replicates. Treatment 1 served as control diet with no rice bran and yeast supplementation, diet 2 and 3 contained 30 and 35% rice bran without yeast supplementation, respectively. Diets 4 and 5 were the same as diets 1 and 2 except that 2 g kg-1 of yeast was added to each. Between 45th and 50th week of age of the birds egg quality trial was conducted to assess haugh unit, shell thickness and yolk index. Results of feed intake, hen day egg production, feed conversion ratio and mortality were not significantly (p<0.05) influenced by dietary treatments. Haugh unit, yolk index and average weight of egg did not vary significantly (p<0.05) between treatments, however, shell weight and shell thickness were significantly affected by the treatments. Total cost of production was higher (p<0.05) for the control group compared to treatments 2, 3 and 5. Revenue generated from sale of eggs was higher for birds on treatment 4 compared to those on treatments 1 and 5 (p<0.05). Net farm income was higher for treatments 2, 3 and 4 compared to the control. It could be concluded from the results of this study that performance of birds was not affected by the levels of rice bran with and without yeast supplementation. However, shell thickness, shell weight and net farm income were significantly affected by the treatments.

  This study was conducted to determine the response of Shika Brown cockerels to graded levels of Lablab purpureus beans, processed by boiling in water for 30 min at 100°C. Six isonitrogenous diets with similar caloric levels were formulated to contain lablab seed meal at 0.0, 7.5, 15.0, 22.5, 30.0 and 37.5%, respectively. Diet 1, which had no lablab seeds and served, as the control, was a groundnut cake-maize based chick diet. Each diet served as a treatment and each treatment was replicated three times in a completely randomized design. There were 30 birds per replicate making a total of 540 birds for the study. Feed and water were provided ad libitum. The experiment lasted 8 weeks. The results obtained showed significant (p<0.05) negative responses of the cockerels to dietary levels of lablab. It was observed that there was a significant (p<0.05) decrease in final weight and weight gain as the level of lablab in the diet increased. Feed efficiency was observed to decrease significantly (p>0.05) as the level of lablab in the diet increased. Mortality was not however significantly (p>0.05) affected by feeding lablab in the diet of the cockerels. Feed cost (/bird) and total cost (/bird) were significantly reduced (p<0.05) as the dietary levels of lablab seed increased. Also organ weights and haematological parameters were not significantly (p>0.05) affected by feeding graded dietary levels of cooked Lablab purpureus beans in the diets of Shika brown cockerels.

  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.
