  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.

  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.

  Abstract: The lablab seeds were cooked for 30 min, sundried for three days and thereafter milled and incorporated into chickens’ diets. Six treatments, comprising of six dietary levels of lablab at 0.0, 7.5, 15.0, 22.5, 30.0 and 37.5%, respectively was fed during the grower’ s phase. Results obtained for the growers phase indicate that final weight (g/bird), weight gain (g/bird) and feed cost (N kg- 1) decreased significantly (p<0.05) as the level of lablab increased in the diet. Feed intake (g/bird and g/bird/day) as well as feed cost (N/bird) and total cost (N/bird) also decreased significantly (p<0.05) as the level of lablab increased in the diet up to 22.5% inclusion level before increasing as the level of lablab in the diets continued to increase. The level of lablab in the diet had no effect on mortality throughout the experimental period. In addition haematological parameters such as Packed Cell Volume (PCV), Haemoglobin (Hb) and Total Protein (TP) were not significantly (p<0.05) affected by feeding diets containing graded levels of cooked lablab beans to pullets. Results obtained during the laying phase indicates that feeding lablab seed meal up to 22.5% in the diets at the growers stage had no significant adverse effect (p<0.05) on final weight, feed intake, feed efficiency, percent henday and henhoused egg production, percent production at peak, kilogramme feed per twelve eggs, feed cost per twelve eggs, Haugh Unit and yolk index. However, age of birds at first egg, age at 50% production and age at peak egg production were increased significantly (p>0.05) with increase in the level of lablab seed meal in the growers diets.

  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.

  A study was conducted in a completely randomized design to evaluate the effect of diets formulated on the basis of four critical essential amino acids (lysine, methionine, tryptophan and threonine) on the crude protein requirement of broiler finisher chickens (28-56 days) reared under tropical environment. One hundred and eighty chickens were used in this experiment. There were four experimental diets each with three replicates (15 birds per replicate). The experimental diets were formulated in a gradual crude protein increase from 18-21 by 1% interval. Diet 1-4 contained 18-21% dietary crude protein respectively. All the diets were formulated to have an additional 10% for the four critical essential amino acids. The performance of chickens fed 19% CP was similar to chickens fed 20 and 21% CP diets in terms of final weight, weight gain and feed conversion ratio. Feeding 18% CP with essential amino acids diet resulted in significantly (p<0.05) lower final weight, weight gain, average daily weight gain and poor FCR than those fed diets higher crude protein diets. Generally, it was observed that chickens fed 19, 20 and 21% CP supplemented with balanced essential amino acids were statistically similar in terms of the carcass weight, dressing percentage, thighs, drumsticks, heart, lung and back weights compared to the chickens fed 18% CP supplemented with balanced essential amino acids. It can be concluded that crude protein requirement of broiler finisher chickens (28-56 days) can be reduced to 19% with essential amino acids supplementation without having any adverse effect on growth, carcass quality and haematological parameters of broiler finisher chickens reared under the tropical environment.
