“…Feed conversion ranged from 4.7 to 7.7 and was negatively (P < 0.05) influenced (P < 0.05) by the WC 6%NaOH inclusion levels, showing that the animals will need to consume greater amounts of feed to convert it to 1 kg LW. The same response was found by Azevedo et al (2012), who detected a linear increase in feed conversion values as they increased the levels of macauba palm (Acrocomia aculeata) cake in finishingsheep diets, with values ranging from 5.5 to 6.4. The apparent digestibility of DM (DMD) differed (P < 0.05) between the diets with 25% and 35% or 40% WC 6%NaOH (Table 4); between the diets with 25% and 40% WC 6%NaOH , this difference was 7.3%.…”

“…For the diet with 25% WC 6%NaOH , DWG was higher than the 205 g observed by Azevedo et al (2012) using tropical grasses as roughage with a roughage:concentrate ratio of 30:70 in the diet. The low NDF content and the higher energy uptake with the increased level of concentrate in this diet contributed to this result.…”

“…It is believed that the intake was not affected by the inclusion of WC 6%NaOH due to the improvement in the fiber digestion with the alkaline agent. The DMI in g/ day were higher than the 82.37 g/unit of metabolic weight found by Azevedo et al (2012) with sheep fed a diet containing 30% roughage and 70% concentrate.…”

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.

“…Análises químicas realizadas nas tortas residuais do fruto da macaúba demonstram que essa poderia ser aproveitada na alimentação de ruminantes, dado o seu alto teor de energia (RUFINO et al, 2011;AZEVEDO et al, 2012). Segundo PEREIRA et al (2011), a inclusão de coprodutos na formulação de rações para animais em produção, substituindo, parcialmente ou totalmente, os alimentos convencionais, consiste em boa alternativa, cujo potencial é ainda pouco explorado.…”

“…AZEVEDO et al (2013), avaliando a inclusão da torta de macaúba na dieta de vacas em lactação, também encontraram valores elevados de extrato etéreo para o coproduto. Durante o experimento observou-se que os animais apresentaram aceitabilidade reduzida nas dietas com altos níveis de TM, o que também pode ter contribuído para a redução no CMS e, consequentemente, na PL.…”

Biocomposites based on macaíba shell (MS) and Polycaprolactone (PCL) were melting processed in this work; seeking better compatibility between PCL, MS was chemically treated with maleic anhydride (MA) and sodium hydroxide (NaOH), in addition, PCL‐g‐MA was used as compatibilizer. The biocomposites' performance was evaluated through Fourier transform infrared (FTIR), thermogravimetry (TG), contact angle, water absorption, scanning electron microscopy (SEM), the tensile experiments were executed according to ASTM D638 and the nonisothermal crystallization kinetics was performed from differential scanning calorimetry (DSC) scans using Pseudo‐Avrami, Ozawa, and Mo models. Chemical treated and compatibilized biocomposites presented better tensile behavior with no significant changes in the thermal stability. Higher HDT was verified on PCL/MS biocompounds due to the MS hardening effect, whereas higher contact angle and water absorption were computed for PCL/MS most due to new ways origin for the water get in as provided by MS. Related to crystallization kinetics Ozawa as displayed in the Appendix S1 failed to fit PCL/MS kinetics whereas Pseudo‐Avrami and Momay be safely used form processing purposes. Summing up, PCL/MS biocomposites were carefully investigated and gathered information may be promptly used in sundry applications as well as be added to the literature database.
