The aim of the present study was to evaluate the effects of Leucaena (Leucaena leucocephala) and Banana flour (Musa cavendishii) on performance of laying hens. Fifty laying hens (3 months of age) were randomly distributed into five experimental groups, each consisting of 10 laying hens. The groups were control (10 laying hens); L6 (Leucaena, 6 g/da...

The study was conducted to determine the intake and weight gain in goats fed varying levels of Faidherbia albida pods. Twenty goats weighing an average of 12.75 kg were used for the study. The animals were weighed and randomly allotted to four different treatments with varying level of Faidherbia albida pods as T 1 (10%), T 2 (20%), T 3 (30%) and T...

... Thanks to pigment content in these leaf meals, it proved that this content increased chicken's skin yellow darkness improved egg yolk color, and increased meat and egg palatability (Hien et al., 2016(Hien et al., , 2017.

... Although Leucaena it is a plant rich in nutrients, it contains tannins, trypsin inhibitors and toxic substances, such as the non-protein amino acid β-[N-(3-hydroxy-4oxo pyridyl)]-α-aminopropionic (mimosine); its fibre level restricts its use by affecting the performance of laying hens according to the inclusion levels (Dumorné, 2018;Oliveira et al. 2014). ...
O objetivo do estudo foi avaliar o efeito da inclusão do feno da folha de leucena em dietas sobre a metabolização de nutrientes, desempenho e características dos ovos de poedeiras comerciais. Foram utilizadas 216 poedeiras com 32 semanas de idade, distribuídas em delineamento inteiramente casualizado com 6 tratamentos, 6 repetições de 6 aves cada, durante 12 semanas. Os tratamentos consistiram em uma dieta formulada com milho, uma dieta formulada com sorgo e outras 4 formuladas com sorgo contendo 2, 4, 6 e 8% de feno da folha de leucena. Foi observada redução linear sobre os coeficientes de metabolizabilidade da matéria seca, proteína bruta, energia bruta e nos valores de energia metabolizável aparente e energia metabolizável aparente corrigida para balanço de nitrogênio. Observou-se redução linear na produção de ovos e na ingestão de energia metabolizável aparente corrigida para balanço de nitrogênio com o aumento da leucena nas dietas. Galinhas alimentadas com dietas contendo 8% de leucena apresentaram menor produção de ovos e ingestão de energia metabolizável aparente corrigida para balanço de nitrogênio em relação as aves alimentadas com o sorgo. A inclusão de 2% de feno da folha da leucena na dieta proporcionou gemas com pigmentação superior às obtidas com as dietas a base de milho. De acordo com os resultados, pode-se incluir até 6% de feno da folha de leucena em dietas de poedeiras comerciais formuladas com sorgo.
... Adult chickens fed with Leucaena leaf meal up to 7% of the diet showed an increase in the use of crude protein and metabolizable energy [75]. Dumorné [76] found positive effects on weight gain, body weight, and feed intake of laying hens with inclusion of Leucaena leaves meal from 6 up to 12 g/bird/day, in comparison with the control diet without Leucaena. Feeding broiler chicken with boiled L. leucocephala meal (10% of the diet) was recommended since it furnished high carcass and meat attributes of broiler chicken [77]. ...
Simple Summary
The need to address the shortage of protein ingredients linked to both territoriality and growing demand pushes research to focus attention on alternative protein sources, both vegetable and animal (insects). This review describes the characteristics, uses, strengths, and weaknesses of Leucaena leucocephala, a legume that can be used in the zootechnical field as an alternative to traditional protein sources for feed formulation.
Abstract
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.
... Seguidamente, el producto se dejó en reposo para disminuir la temperatura hasta una que permitiera su manipulación para ser cortado en ruedas y, posteriormente, secado. Ambos ingredientes se introdujeron en una estufa ventilada durante 48 h a 60°C, con la metodología desarrollada por Dumorné (2018). Cumplida esa etapa, se realizó la molienda en un molino Willey utilizando una criba de 2 milímetros (mm). ...
... Los resultados aquí expuestos permiten asumir que Musa spp., como sustrato complementario energético, conserva la mayoría de indicadores productivos en pollos de engorde, al igual que las aves expuestas al consumo de balanceado comercial Dumorné (2018), comprobó también que la inclusión de Leucaena leucocephala y harina de Musa cavendishii ejerce efecto positivo sobre el incremento de peso, consumo y conversión alimenticia de gallinas ponedoras. Es importante resaltar que las aves de corral carecen de enzimas degradadoras de fibra para descomponer los carbohidratos complejos, lo cual condiciona el hábito de consumo (Thirumalaisamy et al. 2016). ...
Introducción.
La avicultura moderna demanda el desarrollo de estrategias alimenticias que incrementen el nivel de sostenibilidad en las parvadas, lo cual ha generado interés por incluir ingredientes no tradicionales en las dietas para aves.
Objetivo.
Evaluar el efecto de la inclusión parcial de frijol caupí(Vigna unguiculata) y plátano (Musa spp.) sobre parámetros zootécnicos de pollos de engorde.
Materiales y métodos.
Se formuló una dieta isoprotéica (20% PC) e isocalórica (3,7 kcal ED/g) para alimentar durante 42 días 160 pollitos Cobb 500, con sustitución parcial de 0; 18; 20 y 22% el alimento concentrado (AC) por una mezcla experimental (ME) de V. unguiculata y Musa spp. Las aves fueron distribuidas al azar en 16 corrales según los tratamientos (T): T0: 100% AC; T1: 82% AC + 18% ME; T2: 80% AC + 20% ME y, T3: 78% AC + 22% ME y 4 repeticiones. Para evaluar la respuesta productiva, se consideraron los parámetros ganancia total de peso (GTP), ganancia diaria de peso (GDP), factor de conversión alimenticia (FCA), consumo (C), rendimiento en canal (RC) y mortalidad (M).
Resultados.
El tratamiento control (T0) registró la mayor GTP (2,461±0,02 g), GDP (58,60±0,03 g), C (4,247±3,20 g) y FCA (1,73±0,06); sin embargo, el análisis estadístico reveló que el T0 y T1 son estadísticamente iguales, mientras que T2 y T3 presentaron diferencia significativa (p<0,05) entre sí para la mayoría de variables y, frente a T0 y T1. En cuanto al RC, el T0 y T1 difirieron significativamente (p<0,05) con respecto a T2 y T3. Durante el experimento no murieron aves en ninguno de los tratamientos evaluados.
Conclusión.
Sustituir hasta un 18% el AC por una mezcla balanceada a base de V. unguiculatay Musaspp. en pollos de engorde, resulta una alternativa nutricional para la avicultura familiar.
