<b>Inclusion of leucaena leaf hay in the diet of laying hens during the growing phase

Abstract

ABSTRACT. Current experiment evaluated the effects of inclusion of leucaena leaf hay (LLH) on the performance and nutrient digestibility of diets for laying hens during the growth phase (14-18 weeks). Ninety pullets (Rhode Island Red and New Hampshire) were distributed in a completely randomized design with three treatments (0%, 5% and 10% inclusion of LLH) and five replicates, with six birds. Feed intake (g bird -1 day -1 ), weight gain (g bird -1 day -1 ), feed conversion (kg kg -1 ), metabolizable energy intake (kcal bird -1 day -1 ), intake of crude protein (g bird -1 day -1 ), coefficients of dry matter (CDDM) and gross energy (CDCE), nitrogen digestibility (CDN), apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen (AMEn) were evaluated. The inclusion of LLH did not statistically influence CDN, AME and AMEn of diet. However, this inclusion significantly affected CDDM and CDCE, resulting in lower CDDM and CDCE with inclusion of 10%. Whereas the use of nutrients by chicks fed on diets with the inclusion of LLH allowed the same amount of metabolizable energy, inclusion of up to 10% of LLH diet during the growth phase (14-19 weeks) of laying hens (Rhode Island Red and New Hampshire) may be recommended.Keywords: alternative food, poultry, fiber, leucaena, nutrition.Inclusão de feno da folha de leucena na ração de poedeiras na fase de crescimento RESUMO. O experimento avaliou os efeitos da inclusão do feno da folha de leucena (FFL) sobre o desempenho e digestibilidade dos nutrientes das rações para poedeiras em crescimento (14 a 18 semanas de idade). Utilizaram-se 90 frangas (Rhode Island Red e New Hampshire), distribuídas em delineamento inteiramente casualisado com três tratamentos (0%, 5% e 10% de inclusão do FFL) e cinco repetições de seis aves. Avaliou-se o consumo de ração (g ave -1 dia -1 ), o ganho de peso (g ave -1 dia -1 ), a conversão alimentar (kg kg -1 ), a ingestão de energia metabolizável (kcal ave -1 dia -1 ), a ingestão de proteína bruta (g ave -1 dia -1 ) e os coeficientes de digestibilidade da matéria seca (CDMS), da energia bruta (CDEB), do nitrogênio (CDN), energia metabolizável aparente (EMA) e energia metabolizável aparente corrigida para nitrogênio (EMAn). A inclusão de FFL não influenciou estatisticamente CDN, EMA e EMAn da ração. Entretanto, influenciou significativamente os CDMS e CDEB, resultando em menor CDMS e CDEB com inclusão de 10%. Considerando que o aproveitamento dos nutrientes da ração pelas aves alimentadas com a inclusão do FFL possibilitou o mesmo valor de energia metabolizável pode-se recomendar a inclusão de até 10% do FFL na ração de crescimento (14 a 19 semanas de idade) para poedeiras (Rhode Island Red e New Hampshire).Palavras-chave: alimento alternativo, aves, fibra, leucena, nutrição.

Importance of banana flour and its effect on growth performance of broiler

“…Increasing fiber level in the diet may cause several metabolic and physiological effects in the broiler organism such as increase in the rate of endogenous excretion, and reduction in the activity of digestion enzymes and of the feed pathway through the gastrointestinal tract (Araujo & Silva, 2008; Nunes De Oliviera et al, 2014). Shaddel‐Tili, Eshratkhah, Kouzehgari, and Ghasemi‐Sadabadi (2017) have reported that the process of absorption that occurs in the body of the livestock is influenced by the age, so that the feed given to livestock should be adjusted to the age.…”

“…However, the production of adequate food is the biggest challenge for industries (Cullere et al., 2017). Many investigations have been conducted to evaluate the suitability of various feed ingredients as alternative protein and energy sources for poultry (Abdel‐Hafeez Saleh, Tawfeek, Youssef, & Abdel‐Daim, 2018; Azizi et al., 2018; Ebrahimi, Qotbi, Seidavi, Laudadio, & Tufarelli, 2013; Gatrell, Derksen, O’Neil, & Lei, 2017; Nunes De Oliviera, Freitas‐Braga, Thales, Jeromino Do Nascimiento, & Castro‐Lima, 2014). However, scarce interest has been given to banana flour as potential ingredient for poultry diets.…”

Increasing the dietary supply of carotenoids through forage supplementation: Effect on nitrogen and mineral retention in captive Golden pheasants (Chrysolophus pictus)

“…However, green forages contain more fiber and less energy and feeding of excessive forages may depress performance [Horsted et al, ]. There are some studies which indicate that small amounts of green forages can be incorporated into layer diets without any adverse effect on performance [Odunsi et al, ; Kakengi et al, ; Oliveira et al, ]. It is well documented that there is inter‐species difference in feed consumption and nutrient utilization among different species of bird [Sultan et al, ; Sheppard et al, ].…”
