“…In these studies, however, the NDF intake was not limiting (<11 g kg −1 body weight) in any of the inclusion levels of the by-product. Miotto et al (2012) evaluated 0, 21, 38, 62, and 78% of BMB in sheep diets and did not find alterations in DM intake, which was attributed to the large variability in the acceptance of this by-product by the animal species used.…”

-The objective of this study was to evaluate the feeding behavior and feedlot productive performance of dairy-origin steers fed for 84 days ground pearl millet grain-based diets with 0, 120, 240, 360, and 480 g kg -1 of babassu mesocarp bran (BMB) and a standard diet based on ground corn. Thirty Holstein-Zebu steers with average initial body weight of 371.02±27 kg were used. The experimental design was completely randomized, with five replications. Dry matter intake showed better fit with the quadratic regression equation with the inclusion of BMB, reaching a maximum value in diets with 360 g of this by-product. There was no difference for dry matter intake between pearl millet-and corn-based diets. There was no difference in total digestible nutrients intake between diets. The digestibility coefficient of organic matter decreased linearly with the increase in the dietary level of BMB. The digestibility coefficient of organic matter was not different between corn and millet diets. There was no difference in feeding time between diets. Total requirement of metabolizable energy increased linearly with inclusion of BMB. However, total requirements of metabolizable energy did not differ between the corn-and pearl millet-based diets. Average daily gain decreased linearly with the increase in BMB, with adjustment forced by the sharp decline of this variable in diets with 480 g of BMB. There was no difference in average daily gain between corn-and pearl millet-based diets. The inclusion of levels above 360 g of babassu mesocarp bran in pearl millet-based diets reduces the supply of metabolizable energy and the productive performance of feedlot dairy steers.

“…Miotto et al (2012) studied intake and digestibility of Babassu mesocarp meal levels in sheep diets and detected a reduction in EEi for percent BW and g/kg 0.75 with increasing inclusions of the byproduct. This reduction was attributed to the Napier grass silage used in that experiment, whose EE levels were three times superior when compared to Babassu mesocarp meal (1.9% and 0.7% of EE, respectively).…”

“…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.…”

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.

“…The nutritional value of ruminant feed depends largely on the interaction between ingested nutrients and the action of microorganisms in the digestive tract (MIOTTO et al, 2012). The quality of the protein in ruminant diets has been traditionally evaluated by determining the level of digestible protein and less frequently by evaluating the nitrogen balance.…”

Twenty neutered male sheep were subjected to 26 days of a metabolic assay at Embrapa Eastern Amazon in Belém, PA, Brazil (01°26'02"S and 48°26'21"W; altitude 8 m). The trial followed a completely randomized design, with five treatments and four repetitions. Treatment A (control) consisted of a diet containing 100% grass. The diet in treatment B contained 10% CM and 90% grass; that in treatment C contained 20% CM and 80% grass; that in treatment D contained 40% CM and 60% grass; and that in treatment E contained 60% CM and 40% grass. Intake of experimental diet and apparent digestibility coefficient of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ethereal extract (EE), cellulose (CEL), hemicellulose (HEM), and nitrogen balance (NB) were assessed. Results showed that the level of CM replacement significantly affected intake of mineral matter (IMM), crude protein (ICP), ethereal extract (IEE), and cellulose (ICEL), with the highest (P < 0.05) values of IMM, ICP, and IEE being observed for feed in which 60% of grass was replaced by CM, indicating that the acceptance of the experimental diet was good. ICEL decreased as levels of CM replacement increased. At 40% replacement, the apparent DM digestibility coefficient was the lowest (41.54%) and did not statistically differ from diets with 60% (45.74%) and 20% (54.19%) CM replacement. The lowest values for the apparent digestibility coefficients of OM, CP, NDF, and ADF were observed when grass was replaced with 40% and 60% CM. For diets with up to 20% replacement of Mombaça grass by CM, the apparent digestibility coefficients of DM, OM, NDF, and ADF were the highest and did not significantly differ from those of the control treatment. Nitrogen excretion in feces differed significantly; the lowest values were found with 0%, 10%, and 20% CM replacement. Use of CM represents an alternative method of dietary supplementation for ruminants and is a good source of protein and energy, since replacing Mombaça grass with increasing levels of CM led to an increase in the voluntary feed intake by ovines.
