“…When Flores et al (1979) replaced casein with Leucaena and obtained similar results with Rhodes grass, they attributed it to the presence of condensed tannins in Leucaena that protected dietary protein from excessive degradation in the rumen, the same way that formaldehyde protected casein in the rumen. In that case, moderate tannins in Leucaena were shown to be beneficial.…”

The purpose of this study was to determine the effect of varying levels of Leucaena supplement on the intake, flow and digestibility of nutrients of two low-quality forages. Partial digestion methods were used. The overall results showed that the supplementation of veld grass with Leucaena hay improved the performance of veld grass more significantly (P < 0.05) than the supplementation of Eragrostis grass with Leucaena hay. The crude protein of Diets 2-4, which contained veld grass, increased by 67.1%, 95.3% and 130.6%, compared with the control diet, while the in vitro organic matter digestibility increased by 15.5%, 25.7% and 15.24%, respectively. Similarly, neutral detergent fibre content decreased by 6.5%, 14.7% and 23.3%, respectively. Feed intake increased by 22.7%, 14.9% and 11.3%, and crude protein intake increased by 2.13, 2.25 and 2.57 times, respectively. The production of ammonia nitrogen increased by 17%, 38.4% and 44.3%, and volatile fatty acids increased by 31.3%, 28% and 26%, respectively. The flow of non-ammonia nitrogen through the abomasum increased by 3.28, 3.9 and 4.76 times, respectively. The disappearance of organic matter from the rumen increased by 29.3%, 36.2% and 24.7% and in the small intestine increased by 1.8, 2.3 and 2.2 times, respectively. The overall digestibility of organic matter in the whole digestive tract was increased by 9.9%, 16.3% and 9.7%, respectively. In comparison, the crude protein of Diets 6-8, which contained Eragrostis grass, increased by 37.5%, 80% and 103.3%, compared with the control, while the neutral detergent fibre content decreased by 4.8%, 14.8% and 21.6%, respectively. Feed intake increased by 41.3%, 36% and 28.4%, and crude protein intake by 1.93, 2.43 and 2.52 times, respectively. The production of ammonia nitrogen increased by 13.8%, 25% and 21.7%, and volatile fatty acids increased by 18.8%, 17.4% and 14.7%, respectively. The flow of nonammonia nitrogen through the abomasum increased by 1.27, 166 and 1.50 times, respectively. However, there was no significant effect on the flow of the other nutrients. However, the overall digestibility of organic matter was not significantly different from that of the control diet. The conclusion was that the supplementation of the poorer forage with Leucaena was more beneficial and more cost-effective than the supplementation of the better-quality forage with Leucaena.

“…Dairy cattle produce well when fed with L. leucocephala [32,37]. Henke and Morita [38] reported that dairy cows produce milk with higher fat content when they are fed with L. leucocephala compared to similar cows fed on pasture and concentrates or ammoniated rice straw in the grass-based diet.…”

Leucaena leucocephala trees are commonly known as White Lead tree. It is native to Southern Mexico and Northern Central America and spread across many tropical and sub-tropical locations. It has multipurpose uses, such as generation of firewood, timber, greens, fodder, and green manure, as well as to provide shade and control soil erosion. It has been used for medicinal purposes because of possessing multiple pharmacological properties. Studies have shown the presence of various secondary metabolites such as alkaloid, cardiac glycosides, tannins, flavonoids, saponins, and glycosides in this species. In traditional medicine, it is used to control stomach ache and as contraception and abortifacient. In the present study, the global distribution, taxonomy, chemical composition, pharmacological activities, and potential uses of Leucaena leucocephalaare discussed.

“…There are factors peculiar to Leucaena which limit its degradation in the digestive tracts of animals (Flores, et al, 1979;Jones & Bray, 1982;Quirk, et al, 1988;Hammond, 1995;Kaitho, 1997). Therefore, the browse/silage mixtures unlike their corresponding fecal manures maintained higher C: N ratios in the soil similar to that of the control soil.…”

Soil organic carbon (C) and nitrogen (N) decomposition in fecal manure of cattle fed browses of Calliandra (Calliandra calothyrsus), Gliricidia (Gliricidia sepium) and Leucaena (Leucaena leucocephala) browse/maize silage mixtures and maize (Zea mays) silage alone when applied to the soil were investigated in a pot experiment in comparison to the corresponding silages fed. Maize silage alone had the lowest N and a larger C: N ratio, making it a poor quality compost when applied to the soil, but compared to the browse/maize silage mixtures it had the highest level of soluble N as non-protein nitrogen (NPN) which makes much of its N available for soil microbial decomposition of its organic C. Calliandra browse/maize silage mixture had the highest level of fiber-bound N (ADFN), which reduces N availability for soil microbial decomposition of its organic C in spite of its high N content and a narrower C: N ratio. Fecal manure from maize silage alone had a lower level of N and a wider C: N ratio than fecal manure from the other silages fed which would affect its decomposition in the soil, but it had the lowest level of ADFN and much of its N is made available for soil microbial decomposition of its organic C. Soil samples after 12 weeks of the experiment showed that Calliandra browse/maize silage mixture maintained the highest level of C in the soil, while maize silage alone maintained the lowest level. Also soils treated with fecal manure from the other browse/maize silage mixtures maintained higher levels of C than fecal manure from maize silage alone. Organic C levels were lowest at 8 weeks of the experiment for all treatments and rose to the original levels at 12 weeks which could have been as a result of biotic and hydrologic factors coupled with soil aggregation. Decomposition of organic N followed a similar trend as organic C. The two elements are linked in both plant inputs in the soil and in the eventual soil humic substances. The soils treated with browse/maize silage mixtures maintained C: N ratios that were similar to that of the control soil and higher than those of the fecal manure treatments. Thus, in spite of the added silage materials to the soil, rapid decomposition of organic C could not occur to reflect benefits of adding the silage materials to the soil. Thus, fecal manure, particularly from feeding animals on browse/forage diets is more beneficial in the soil as it would decompose more readily releasing the plant nutrients they contain.

The influence of the legume Leucaena leucocephala and formal-casein on the production and composition of milk from grazing cows

Abstract: Twenty-four lactating Jersey cows, grazing a 3-week regrowth of nitrogen-fertilized Chloris gay ana cv. Pioneer pastures selected a diet containing 18% crude protein and were given 0, 2 or 4 kg/day of fresh Leucaena leucocephala or 250 g/day of formal-casein.
