    Effects of dietary inclusion of chickpeas or mung beans on the performance of male broiler chicks
    Lodebo, Beriso ( 1991)
    Male broiler chicks (Inghams) were reared to 5 days of age on a commercial starter ration and then fed a control diet or a diet containing 10, 20, 30, 40 or 50% of either chickpeas or mung beans up to 28 days of age. At the end of the feeding trial, a sample of birds from each group were sacrificed for carcass and visceral organ assessment. The chickpeas, mung beans and other ingredient grains were assayed for trypsin inhibitor (TI), chymotrypsin inhibitor (CTI), tannin and haemagglutinin activities. The diets were assayed for apparent metabolizable energy (AME), TI and CTI. Average daily feed intake (FI) ranged from 66.89 � 1.96 to 76.23 1.96g showing a significant (P< 0.01) reduction in FI with increasing level of either bean. Average daily live weight gain (ADG) varied from 37.38 � 1.07 to 45.43 � 1.61g showing a linear and highly significant (P< 0.001) decrease in ADG as the level of both chickpeas and mung beans increased. Feed conversion efficiency deteriorated with increasing level of beans in the diets (P< 0.001) and chickpeas showed poorer FCR than mung beans (P< 0.01). AME of the diets ranged from 11.4 to 12.6 MJ/Kg indicating a significant (P< 0.05) reduction in energy efficiency as the level of either bean increased. Fasted live weight of chicks on 28th day of age ranged from 928 90 to 1114 � l Og (P< 0.001). Birds grown on mung bean diets had nonsignificantly (P> 0.05) higher live weight and carcass output than those on chickpeas while those grown on the, control diet yielded significantly higher (P< 0.01) carcass output. Actual weights of both pancreas and intestines and their weights as percentage of live weight significantly increased (P< 0.001) with increasing levels of either bean and the increase was comparatively greater for chickpeas than for mung beans. There was no significant variation in actual weight of liver but the weight of liver as percentage of live weight significantly increased (P< 0.05) as the level of either bean increased. TI, CTI, tannin and haemagglutinating activities in chickpeas and mung beans were 3.25 vs 3.35, 4.30 vs 0.24, 6.4 vs 9.4mg/g and 6.4 vs 51.2HU/g respectively while TI and CTI activities in the control diet wwle 0.04 and 0.00 respectively. Levels of ANFs increased as level of either bean in the diet increased, hence performance of chicks declined linearly. Among the ANFs detected, the level of total protease inhibitors (TI + Cf I ) activity gives clear explanation for the variation in chick performance. In addition, it was suggested that the poorer performance of chicks on chickpea diets could also be attributed to lower digestibility and availability of carbohydrates in chickpeas. 2

    Growth and digestibility in finishing pigs fed various levels of raw mung beans (Phaseolus aureus [Roxb.] var. Berkin)
    Wiryawan, I Ketut Gede ( 1991)
    Two experiments were conducted to evaluate raw mung beans (Phaseolus aureus [Roxb] var. Berkin) as a source of protein and energy for finishing pigs. In the first experiment, 6 cross-bred (Landrace X Large White) boars of 53 kg liveweight were used to determine the digestible energy (DE) content of ground mung beans by substitution where 30% ground mung beans were included in a basal (wheat) diet at the expense of wheat. The DE content of mung beans was 16 � 0.9 MJ/kg DM. In the second experiment, 24 boars of 58 - 65 kg liveweight were allocated to 6 groups of four and individually fed diets containing 0% (control), 10%, 15%, 20%, 25% and 30% mung beans substituting for the same amount of soybean meal. All diets contained 14.5 MJ DE/kg and an estimated 0.65 g lysine/MJ DE.. Daily feed allowance was restricted to approximately 35 MJ DE. There was no significant difference (P>0.05) between treatments in average daily gain (ADG), feed conversion ratio (FCR), backfat (P2) or relative weights of pancreas, liver, kidney, stomach, small intestine and large intestine. The ADG and FCR were 0.96 � 0.02 kg and 2.60 � 0.05 units of feed/units of gain respectively, whilst P2 was 15.9 � 0.27 mm. The weight of the pancreas, liver, kidney, stomach, small intestine and large intestine relative to body weight were 0.15 � 0.01; 2.07 � 0.03; 0.39 � 0.01; 0.61 � 0.01; 1.96 � 0.03 and 1.41 � 0.03 per cent respectively. Organic matter (OM) and ether extract (EE) digestibilities were not affected by the levels of mung beans, but levels beyond 20% significantly (P< 0.05) decreased apparent digestibility of crude protein (CP) and increased digestibility of neutral detergent fibre (NDF). Under the condition of this study, this variety of mung beans can be incorporated in finisher diets up to 30% without negative effects on growth performance.
