“…The diet with the highest (P > 0.05) TDN content was that with 25% of inclusion of whole coconut, which can be explained by the higher proportion of concentrate. The DWG obtained with this diet was higher than that found by Xenofonte et al (2008) using a diet containing 71% TDN.…”

Nutritional value of whole coconut, coconut powder, and coconut fiber treated with sodium hydroxide for sheep

et al. 2016

The growing consumption of green coconut -fresh and industrialized -in Brazil generates a large volume of wastes and coproducts that justifies the search for alternatives for their use in animal feeding. The most limiting factor to the inclusion of these coproducts in ruminant diets is their high fiber content, which may restrict intake and performance. The present study determined the composition and in vitro dry matter degradability of whole coconut, coconut powder, and coconut fiber treated with sodium hydroxide (0%, 3%, and 6%) and the effect of including whole coconut hydrolyzed with 6% sodium hydroxide at different concentrations (25%, 30%, 35%, and 40%) in the diet on apparent digestibility of nutrients, performance, and feeding behavior of sheep. Alkalinization decreased the hemicellulose, NDF, and ADF contents of the evaluated coproducts. Whole coconut and coconut powder provided greater in vitro degradation of DM compared with coconut fiber, with highest values obtained with the inclusion of 6% sodium hydroxide. Inclusion of whole coconut in the diets did not affect the intakes of DM, CP, NDF, and ADF, but influenced weight gain, feed conversion, and apparent digestibility of DM and NDF. Regarding the feeding behavior of the animals, the inclusion of whole coconut in the diet only affected their rumination time. Whole coconut hydrolyzed with 6% NAOH can be included in diets for feedlot sheep at up to 35% without reducing intake or weight gain.Index terms: Cocos nucifera; NaOH; coproduct. RESUMOAvaliou-se a composição química e a degradação in vitro da matéria seca do coco integral, do pó de coco e da fibra de coco tratados com hidróxido de sódio (NaOH) e o efeito da inclusão do coco integral hidrolisado com 6% de NaOH sobre a digestibilidade aparente dos nutrientes, o desempenho e o comportamento ingestivo em ovinos -0%, 3% e 6% -e o efeito da inclusão do coco integral hidrolisado com 6% de hidróxido de sódio em diferentes concentrações na dieta -25%, 30%, 35% e 40% -sobre a digestibilidade aparente dos nutrientes, o desempenho e o comportamento ingestivo, em ovinos. A alcalinização diminuiu os teores de hemicelulose, FDN e FDA dos coprodutos avaliados. O coco integral e o pó de coco apresentaram maior degradação in vitro da MS em relação a fibra de coco, com maiores valores obtidos com a inclusão de 6% de hidróxido de sódio. A inclusão de coco integral nas dietas não afetou o consumo de MS, de PB, de FDN e de FDA, mas influenciou o ganho de peso, a conversão alimentar e a digestibilidade aparente da MS e da FDN. Quanto ao comportamento ingestivo dos animais, só houve efeito de inclusão do coco integral na dieta sobre o tempo de ruminação. O coco tratado com 6% de NaOH pode ser utilizado em até 35% na dieta de ovinos, pois não reduz o consumo e o ganho de peso desses animais.

“…Special care has to be taken when using Babassu coproducts, even in diets calculated to have the same NDF content. Previous researches have related the decrease in the DMi due to physical factors that may cause ruminal filling (SOUSA JUNIOR et al, 2007;XENOFONTE et al, 2008).…”

“…Current researches seek the chemical composition of Babassu co-products and their inclusion level recommendations, such as Babassu meal and cake (ABDALLA et al, 2008;SOUSA JUNIOR et al, 2007;XENOFONTE et al, 2008), as well as mesocarp meal type II and I (MIOTTO et al, 2012;SOUSA et al, 2014). However, to our knowledge, no research has provided inclusion level recommendations for ruminant diets with Babassu endocarp meal types II and I.…”

Nutritional evaluation of babassu endocarp meal type II with different inclusions in sheep diets

Industrialization of the Babassu coconut for edible oil production generates many co-products and has great potential to be used in ruminant nutrition. The aim of this study was to evaluate the effect of different inclusions of endocarp meal type II of Babassu coconut (BEMII) on intake and digestibility of sheep diets. Twenty non-castrated male sheep with an undefined breed were distributed in a completely randomized design with four treatments and five replications. The animals received an experimental diet with increasing inclusions of BEMII (0.0%, 7.5%, 15.0%, and 22.5%). Increasing additions of the coproduct negatively influenced dry matter intake (g/BW and g/kg0.75). Crude protein intake (in grams) per day decreased linearly with the inclusion of BEMII, presenting a reduction of 49.35 g/d. The inclusion of 7.5% showed the best response for energy balance among all inclusions and presented the closest nitrogen balance value when compared to the control group; therefore, this inclusion percentage is the best for endocarp meal utilization.

“…Reference [21] found a decreasing linear effect on DM intake, when assessing the inclusion (0, 10, 20, and 30%) of babassu meal in the diet of sheep. This result demonstrates that though distinct babassu byproduct was used in this research, it has the same fibrous characteristics, which may affect the dry matter intake due to physical factors of rumen fill.…”

The aim of this study was to evaluate the effect on intake, apparent digestibility, and ruminal constituents of sheep in response to the addition of increasing levels of babassu mesocarp flour (BMF) to the diet. Twenty crossbred sheep (29.17 ± 2.23 kg) were used in a randomized complete block design. Lambs were confined for 21 days, with 16 days for diet adaptation and 5 days for data collection, in which they were fed an isonitrogenous diet (16.5 ± 0.2 CP, DM basis) containing 70% of concentrate and 30% (DM basis) of Tifton 85 hay. Increasing levels of BMF were 0, 10, 20, and 30% (DM basis). There was a quadratic effect (P < 0.05) on the DM intake, nutrients intake, and digestibility of CP and NFC. The digestibility of DM, OM, TC, and NDF decreased linearly, while EE digestibility increased linearly with increasing levels of BMF. The high NDF content presented in the chemical composition of the babassu mesocarp flour ranked the same as fibrous food, which can limit the inclusion in the diet of high production animals. So, babassu mesocarp flour is an alternative for energy source in lambs feed and can be added at levels up to 10%.
