13. Use of elephant grass (Pennisetum purpureum) as substrate for cellulase and xylanase production in solid-state cultivation by Penicillium echinulatum
Abstract The high cost of the enzymes used for the hydrolysis of lignocellulosic biomass is one of the bottlenecks in the production of second-generation ethanol and the use of local biomass, such elephant grass, can help to reduce this cost. In this investigation elephant grass biomass was evaluated as a carbon and inducer source of production of cellulases

14. BRS Kurumi and BRS Capiaçu - New elephant grass cultivars for grazing and cut-and-carry system
Abstract Cultivar BRS Kurumi is characterized by short plant height, short internodes, high dry matter production (29.25 t ha-1yr-1), has a high nutritional value and is recommended for the cut-and-carry system or grazing. Cultivar BRS Capiaçu, indicated for silage and the cut-and-carry system, has tall upright growth, high dry matter production (49.75 t ha

15. Performance and metabolite profile of dairy cows fed tropical grasses and concentrates containing crude protein with low or high degradability
ABSTRACT Ten Holstein-Zebu crossbred cows distributed into two simultaneous Latin squares (5 × 5) as a 2 × 2 factorial arrangement formed by chopped sugarcane or elephant grass silage, both with high or low protein degradability supplements and a corn silage as a control treatment, were compared using orthogonal contrasts. The studied variables were the pe

16. Nutritional evaluation of elephant-grass silages with different levels of by-products from the cashew juice industry
ABSTRACT This study was conducted to evaluate the intake, apparent digestibility (AD), and degradability in situ of elephant grass (Pennisetum purpureum Schum) silages containing 0, 35.0, 70.0, 105.0, and 140.0 g kg-1 by-product from dried cashew apple (DCBP) (as fed basis). A completely randomized design with four replicates was adopted. For the study of de

17. Degradação e produção de gases in vitro de glicerina da cadeia produtiva do biodiesel
his study was realized to evaluate the production of gas and volatile fatty acids when glycerin was used to replace four forage species through the use of a semi-automated technique in vitro. The experimental design included 4 treatments and 4 replications. The treatments consisted of increasing levels of glycerin (0, 30, 50 and 70%), which was used to repla

18. Forage cactus associated with different fiber sources for lactating Sindhi cows: production and composition of milk and ingestive behavior
The objective of this study was to evaluate the association of forage cactus with different fiber sources (elephant grass hay - EGH; corn straw - CS, hay of cassava shoots - HCS; fresh sugarcane bagasse - FSB; and hydrolyzed sugarcane bagasse - HSB) on the milk yield and composition and the feeding behavior of lactating Sindhi cows. Five cows with average bo

19. Elephant grass ensiled with wheat bran compared with corn silage in diets for lactating goats
The objective of this study was to evaluate the use of wheat bran as an additive in elephant-grass silage on intake and digestibility of the nutrients, ingestive behavior, and yield and chemical composition of milk. Eight goats with 45 days of lactation were distributed in a (4 × 4) Latin square design.The treatments consisted of corn silage (CS), elephant-

20. Forage cactus associated with different fiber sources for lactating Sindhi cows: intake, digestibility and microbial protein production
This experiment was carried to evaluate the effect of forage cactus with different fiber sources (elephant grass hay [EGH], corn straw [CS], hay of cassava shoots [HCS], fresh sugarcane bagasse [FSB], and hydrolyzed sugarcane bagasse [HSB]) on intake, apparent digestibility and macrobiotic protein production of cows. Five cows with 265 kg average body weight

21. Kinetic study of the catalytic pyrolysis of elephant grass using Ti-MCM-41
This work aimed to study the kinetics of thermal and catalytic pyrolysis using Ti-MCM-41 as catalyst in order to assess the catalytic pyrolysis efficiency compared to thermal pyrolysis of elephant grass. Ti-MCM-41 molecular sieve was synthesized by hydrothermal method from hydrogel with the following molar composition:1.00 CTMABr: 4.00 SiO2:X TiO2: 1 + X Na2

22. Forage mass and stocking rate of elephant grass pastures managed under agroecological and conventional systems
The objective was to evaluate elephant grass (Pennisetum purpureum Schum.) pastures, under the agroecological and conventional systems, as forage mass and stocking rate. In the agroecological system, the elephant grass was established in rows spaced by 3.0 m from each other. During the cool season ryegrass (Lolium multiflorum Lam.) was established between th

23. Tratamentos térmico e químico para remoção de óxidos alcalinos de cinzas de capim elefante
Elephant grass ash (EGA) was produced at 700 °C, with two different treatments: hot water (EGAhw) or acid solution (EGAas). The efficiency of the treatments at removing the potassium oxide was evaluated with the aim of using the EGA as a pozzolanic mineral addition for cement-based composites. Characterizations were carried out by X-ray fluorescence (XRF),

24. Chemical composition and nutrient degradability in elephant grass silage inoculated with Streptococcus bovis isolated from the rumen
Objetivou-se avaliar a composição químico-bromatológica e a degradabilidade in situ de silagens de capim-elefante inoculadas com Streptococcus bovis isolado do rúmen bovino. O delineamento experimental foi o inteiramente casualizado, com quatro tratamentos e seis repetições: Silagem de capim-elefante; Silagem de capim-elefante inoculada com 106 CFU/g
