“…Multipurpose trees were also complained of anti nutritional factors (Reed et al, 1990;Melaku et al, 2004), which could significantly limit their utilization. These results are also close to the findings of Yami et al (2000) who reported that the inclusion of varying levels L. leucocephala leaves in the diets had significantly (P < 0.05) affected body weight gain.…”

A study was conducted to determine effect of supplementation with isonitrogenous level of concentrate mixture (CM; 33% noug seed cake (NSC) and 67% wheat bran (WB)), alfalfa, lablab, and Leucaena leucocephala (LL) on feed intake, digestibility, daily body weight gain (ADG) and net return of sheep kept on Rhodes grass hay (RGH) basal diet. Twenty four yearling male Dorper×Afar F1 crossbred sheep were used in completely randomized block design blocked by initial body weight into 6 blocks of 4 animals and allocated to one of the treatments. Treatments were RGH fed ad libitum to all treatments plus 300 g/day CM (T1), 286 g/day alfalfa hay (T2), 326 g/day lablab hay (T3) and 299 g/day LL hay (T4). The study contained 90 days feeding and 7 days digestibility trials. The CP, NDF and ADF contents of RGH was 11, 77 and 51%, respectively. The CP contents of NSC, WB, alfalfa, lablab and LL were 32, 17, 23, 20 and 22%, respectively. Among the supplements alfalfa and lablab had relatively higher NDF and ADF levels. Total DM intake differed among treatments and was greater (P<0.05) for T2 and T4 than T3, and values for T4 was greater than T1 (P<0.001) (715, 727, 682 and 809 g/day for T1, T2, T3 and T4, respectively). The CP intake was 103, 110, 92, 130 (SEM = 5.83) and was in the order of T4 > T1 = T2 > T3 (P<0.05). Apparent DM digestibility ranged from 62-66% and was lower (P<0.05) for T2 than T1 and T4, while values for T3 was similar (P>0.05) with all other treatments. The apparent digestibility of CP was greater for T1 than T2 and T3, but values for T4 was similar with the other treatments (82.3, 78.7, 78.3 and 80.4 (SEM = 0.02) for T1, T2, T3 and T4, respectively). ADG was 65, 45, 40 and 69 g/day (SEM = 8.36) for T1, T2, T3 and T4, respectively and the values were greater (P<0.05) for T1 and T4 as compared to the other two treatments, while other mean values were similar (P>0.05). The net return in the currents study was 836, 797, 888 and 982 ETB. Thus, based on biological performance and net return, T4 and T1 outweighs other treatments. However, all supplements used in this study induced favorable ADG and thus can be employed in feeding systems depending on their availability and relative cost.

“…In contrast with Gupta et al (1988), who reported that the reduction in intake of buffaloes has been related to an increased proportion of leucaena in the diet. However, previous studies suggested that the improved intakes were not as high as the intakes of ruminants fed diets containing 34% (Haque et al 2008) and 45% (Yami et al 2000) of leucaena. The digestibility of nutrients being the highest in SB and MB fed diets containing 25% and 50% of leucaena, respectively.…”

Four Thai swamp buffaloes (SB) and four Murrah buffaloes (MB) fed a based diet of fresh ruzi grass (Bachiaria ruziziensis) with an increased proportion of fresh leucaena leaves. Intake of nutrients in animals increased when ruzi grass was mixed with leucaena. Digestibility of nutrients were the highest in SB and MB fed diets containing 25% and 50% of leucaena, respectively, and nitrogen (N) balances in both animal breeds were varied among diets. The regression equation coefficient of mimosine + DHP in the urine was twice as high in SB than in MB. Urinary purine derivatives excretion rate in SB was higher than that in MB. Plasma triiodothyronine and thyroxine declined in both animal breeds fed a diet containing >1 g mimosine intake/kg BW(0.75)/day. Plasma urea-N was the lowest in SB, but the highest in MB when fed a diet containing 84% of leucaena. Plasma β-HBA in SB have declined when diets contained >50% of leucaena but that in MB was not affected by any diet. In conclusion, the effect of leucaena in diet upon buffalo breeds depends on the proportion of leucaena in the diet, mimosine contents and condensed tannins components.

“…Data were analyzed using General Linear Models procedures of SAS (1990). First, subsequent treatments of Yami et al (1999) did not influence responses in this experiment and, therefore, were not considered. Data were analyzed by breed as a split-plot with a model containing shedding status (main plot), time after initial Leucaena consumption (subplot), and their interaction.…”

Thirty Angora (16±2 kg) and 20 Spanish (19±2 kg) 8-month-old doelings, having not previously consumed Leucaena leucocephala, were used to determine effects of dietary inclusion of a moderate level of Leucaena on fleece shedding and subsequent fibre characteristics. A diet of 22.5% Leucaena leaf meal (0.17% mimosine in total diet dry matter) was consumed ad libitum for 8 days starting on November 13, with daily mimosine intake in the first 3 d averaging 56 mg/kg body weight. At d 10, fleece shedding was clearly visible in 17 of the 30 Angora doelings and in 9 of the 20 Spanish doelings. Doelings in which the visual shedding score was above 2 (5-point scale: 1 = no shedding and 5 = excessive shedding; mean of cashmere and guard shedding scores for Spanish doelings) on d 19 were categorized as exhibiting a shedding response to Leucaena. By d 35, six Angora and three Spanish doelings had completely shed fleece. Clean mohair growth rate in Angora doelings was lower (PO.05) for shedding vs nonshedding doelings on d 8 to 40 (0.29 vs 0.68 mg/ (cm 2 d* 1 )) but similar (P>0.10) between shedding groups on d 41 to 63 (1.51 vs 1.46 mg/(cm 2 d 1 )), although cashmere growth rate was not different (P>0.10) between shedding groups on either d 8 to 40 or d 41 to 63. Secondary follicle activity was lower (PO.05) on d 8 for shedding than for nonshedding Angora doelings (89 vs 99%), but activity on d 63 was similar (95 and 96%, respectively). Secondary follicle activity for Spanish does was similar between shedding groups on d 8 and 63 (P>0.10). In conclusion, feeding of Leucaena holds promise as a means of inducing fleece shedding in goats, apparently without marked subsequent effects on productivity. However, further research with higher dietary levels of mimosine is necessary.
