Farelo de manga na dieta de cordeiros em confinamento

Abstract

 RESUMOAvaliou-se o efeito da substituição do milho por farelo de manga em dietas para ovinos. As características avaliadas foram: consumo e digestibilidade aparente da matéria seca (MS), da proteína bruta (PB), da fibra em detergente neutro (FDN), da matéria orgânica (MO), do extrato etéreo (EE), da energia bruta (EB), da energia digestível (ED), dos carboidratos não fibrosos (CNF) e dos carboidratos totais (CT). Vinte e quatro cordeiros Santa Inês foram distribuídos em delineamento inteiramente ao acaso, com quatro tratamentos, constituídos pelas porcentagens de substituição do milho pelo farelo de manga  0, 33, 66 e 100% , com seis repetições. A matéria seca fecal foi estimada utilizando-se o indicador LIPE ® . Não houve efeito da inclusão do farelo de manga sobre o consumo dos nutrientes e nos coeficientes de digestibilidade. Os consumos de EB e ED, em kcal/gMS, aumentaram linearmente com a inclusão do farelo de manga. O farelo de manga pode substituir o milho em dietas para ovinos, sem comprometer o consumo e a digestibilidade dos nutrientes, indicando a possibilidade de uso na dieta desses animais como alimento alternativo.Palavras-chave: fruta, confinamento, consumo, coprodutos, digestibilidade (0, 33, 66 and 100%) with six replicates. The fecal dry matter was estimated using LIPE ® external marker. There is no effect of mango meal inclusion levels on the intake and apparent digestibility. The intakes of GE and DE in kcal/gDM increase linearly with mango meal inclusion. The mango meal can replace corn in diets for lambs without compromising the intake and digestibility of nutrients, indicating potential as an alternative feed. ABSTRACT The effect of replacing corn meal with mango meal in diets of feedlot lambs was evaluated. Apparent digestibility and intakes of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), organic matter (OM) (EE), gross energy (GE), digestible energy (DE), non-fiber carbohydrates (NFC) and total carbohydrates (TC) were evaluated. Twenty-four Santa Inês lambs were distributed in a randomized design with four treatments, consisting of the replacement levels of corn meal by mango

Silage or fresh by-product of peach palm as roughage in the feeding of lambs

“…Some other studies utilizing the same roughage:concentrate ratio have found NDF digestibilities of 56.6 % in a diet with Tifton 85 hay (Costa et al 2012) and 78.7 % in a diet with fresh Elephant grass (Aragão et al 2012), which demonstrates compatibility of the values found in the present experiment with those found in the literature.…”

“…The diets with concentrate presented similar apparent DM digestibility to the values observed in diets with the same roughage:concentrate proportion using corn silage (Moreno et al 2010)-78.7 %; Elephant grass hay (Lima et al 2012)-80.1 %; and fresh Elephant grass (Aragão et al 2012), with 81.8 % of digestibility. Diet FU, which did not have concentrate feeds, showed an apparent DM digestibility close to the values observed by Bringel et al (2011) and Miotto et al (2012)-59.4 and 51.3 %, respectively-in diets with Elephant grass silage only.…”

Effect of Dietary Partial Replacement of Corn Grains by Mango Seeds on Productive and Reproductive Characterization of Damascus Goat Bucks at Prepubertal Stage

“…Replacement of the corn grains (33%) by MSM was recommend by Silva et al (2016), because of the better fermentation of fiber carbohydrates and reduces feeding costs. Aragão et al (2012) evaluated corn grains replacement with MSM in sheep diets and found no effects on nutrient intake, even with 100% replacement, demonstrating its acceptability. These results may indicate that increasing MS level more than 30% in the diet may has no effect on growth performance of the animals, because MS up to 30% in our study resulted in the best productive performance of kids.…”

“…Several authors studied the effect of MS inclusion in the diet on growth performance of sheep (Aragão et al, 2012), goats (Silva et al, 2016), and rabbit (Teye et al, 2020). The information on the influence of MS replacement in the diets on reproductive performance of small ruminants is rare.…”

Replacement of corn with mango meal for dairy goats

“…In general, mango fruit is rich in carbohydrates and organic acids, which are important energy and flavor providers, with volatile compounds as the factors responsible for the flavor (Liu et al, 2013). Aragão et al (2012) evaluated corn replacement with mango meal in sheep diets and found no effects on nutrient intake, even with 100% replacement, demonstrating its acceptability. On the other hand, Cavalcante et al (2006) reported that inclusion of dehydrated mango above 36.1% DM caused a decrease in nutrient intake of sheep.…”
