“…The CP content of dried Leucaena leaves was 30.1% higher than cassava. This content was within the range of 24 to 34% reported by Verdecia et al (2019) and low compared to the 40.1% DM reported by Barwani et al (2022). This trend was similar for ash, organic matter, and crude bre.…”

This experiment was conducted to investigate the effect of dried Leucaena (Leucaena leucocephala) and cassava (Manihot esculenta) leaves on feed intake, milk production, and milk composition of Holstein Friesian x Ankole crossbred cows. Three cows in early lactation, with initial milk production of 4 ± 1.20 kg/day and 359 ± 24 kg average live body weight, were randomly assigned to the experimental diet in a 3x3 Latin square design. Three 15-day experimental periods were adopted (1 to 10-day: diet adaptation and 11 to 15-day: data collection). Cows were fed on a freshly chopped Guatemala grass diet supplemented with 1.25 kg DM of brewers’ spent grain (control). The experimental diets were similar to the control diet differing in the presence of dried Leucaena or cassava leaves, both at the inclusion rate of 20% of the basal diet intake. Total dry matter intake, nutrient intake, milk production, and milk composition showed significant variation among treatments. Cows supplemented with dried cassava leaves had higher total dry matter intake and organic matter intake. Leucaena significantly increased (p < 0.001) daily milk production by 15% compared to cassava (3%). Leucaena had a higher milk fat content (38.44 g), while cassava and the control diet had higher milk protein (38.53 and 38.43 g), lactose (56.79 g and 56.111 g), and not-fat solids (102.41 g and 101.27 g). These results indicate that dried Leucaena and cassava leaves can be used as protein supplements for Guatemala grass basal diet for crossbred cows to improve milk production and quality.

“…The green leaves and legumes can be used for grazing or as fodder to be distributed in the animal feeder, administered in a fresh state or in pellets. Season of the year and cutting age affect chemical composition and digestibility of Leucaena forage; Verdecia et al [ 50 ] found that the cell wall components (neutral detergent fiber, NDF; acid detergent fiber, ADF; lignin), calcium, and silica as well as the fiber-to-nitrogen (N) ratios (NDF/N and ADF/N) increased with the regrowth age in the rainy season. Meanwhile, crude protein (CP), cell content, in vitro dry matter digestibility (IVDMD), and in situ dry matter digestibility (ISDMD) decreased; similar trends were observed for NDF, ADF, lignin, NDF/N, and ADF/N (increase with age) and for CP, cell content, and IVDMD (decrease with age) during the dry season.…”

In tropical and subtropical regions, as well as in the internal and/or marginal Mediterranean areas, one of the most important problems related to animal production is represented by the inadequate nutritional supplies. The low productivity of the animals, often connected to reduced annual growth, is, in fact, not infrequently attributable to the low nitrogen content and the high fiber content of the local plant species and crop residues that constitute the base ingredients of the rations commonly adopted by farmers. The use of the supplementation with arboreal and shrub fodder, although often containing anti-nutritional factors and toxins that limit its use, could be a profitable way to alleviate the nutritional deficiencies of the basic diets. Leucaena leucocephala (Lam.) De Wit is native to Central America and widely naturalized in the majority of Latin American countries. It is a legume suitable for tropical and subtropical environments including the countries of the Mediterranean area. Moreover, its spread is desirable if we consider the multiple uses to which it is suitable, the considerable amount of biomass produced, and its role in preserving the environment. The aim of this work was to highlight the characteristics of Leucaena that can justify its wide diffusion. A structured analysis of strengths and weaknesses was performed accordingly. Being a good protein source for feeding livestock, it could be a species to be introduced in the inland areas of the Mediterranean countries as an alternative protein source; the limit represented by the presence of anti-nutritional factors could be overcome by feed processing and by launching targeted research programs.

“…The determination of secondary metabolites with state-ofthe-art equipment and reagents with a certain chemical specification that make their analysis costly and limit the number of samples that can be performed. There is evidence that the production of these is carried out by the plant as a defense mechanism and from the primary metabolites (sugars and nitrogen) which vary according to the regrowth age [1][2] [3], hence the validity of the models described by Verdecia [15], so that with the use of appropriate mathematical methods, time and resources can be saved to calculate or predict these variables. It is also worth noting that the results achieved on the content of sucrose, glucose, fructose and nitrogen and their variability with age (forage maturity) are within the range described in the international literature for G. Sepium and other shrubby forage plants used in livestock [5][7] [11][12] [20].…”

“…For millions of years, many plant species survived thanks to their ability to produce substances that protect them from predators. Even though several of these compounds (condensed tannins, phenols, alkaloids, oligosaccharides and saponins) can produce a violent and immediate reaction, in most cases they have a subtle effect that manifests itself with prolonged ingestion [3].…”

The objective is to estimate the content of secondary metabolites in Gliricidia Sepium from the age and content of primary compounds (nitrogen, fructose, glucose, and sucrose). The present study was developed following a randomized block design, with three treatments (60, 120 and 180 days) and n repetitions. Nitrogen (N), glucose (Glu), fructose (Frut) and sucrose (Suc) content were evaluated for validation. In addition, mathematical models were validated for the estimation of secondary metabolites from the primary ones and regrowth age. To establish the functional relationship between age and primary metabolites, regression equations were analyzed. Reporting a decrease for N, Glu, Frut and Suc with the highest values at 60 days, and quadratic equations with R2 greater than 0.91 were adjusted. The regrowth age had a marked effect on the contents of primary metabolites (N, Glu, Frut and Suc), which explains the close relationship through the established regression equations. As well as it was evidenced that the validation of the models for the prediction of secondary metabolites in both periods of the year, can be applied due to the dependence of these compounds on their precursors (nitrogen and sugars).
