Infuence of ensiling time and Elephant Grass silage alkaline pretreatment in anaerobic co‑digestion with vinasse for met...
This study investigated the anaerobic co-digestion of sugarcane vinasse (V) and elephant grass silage (S) to produce methane. Box-Behnken experimental design was applied to verify the statistical efects of the elephant grass ensiling time (40, 80 and 120 days), alkaline pretreatment of elephant grass silage (0.5, 2.25 and 4.00% w/v NaOH) and S:V mi...
Perfil fermentativo, valor nutricional e estabilidade aeróbia de silagens mistas de capim-elefante e cunhã.
...
Objetivou-se avaliar o efeito da inclusão de cunhã na dinâmica fermentativa, qualidade nu-tricional e estabilidade aeróbia de silagens mistas de capim-elefante. Níveis de cunhã (0, 20, 40, 60 e 80% na matéria natural) foram adicionados às silagens de capim-elefante. Adotou-se o delineamento inteiramente casualizado, com 5 tratamentos e 3 repetições...
Milk fatty acid profile of cows grazing elephant grass BRS Kurumi pasture with and without energy supplementation.
This study evaluated the effects of energy supplementation on the intake and milk fatty acid composition of cows grazing BRS Kurumi elephant grass pasture during the rainy season. Two treatments (with and without supplementation) were evaluated using a switchback design with six Holstein × Gyr dairy cows after the peak of lactation. The average mil...
Potential use of vitiviniculture waste in mixed cactus pear silages with elephant grass in lamb diet.
...
The aim was to evaluate intake, digestibility, water balance, nitrogen balance, ingestive behavior, performance, and carcass traits of lambs on diets containing levels of vitiviniculture waste in mixed cactus pear silages with elephant grass. Twenty-four crossbred male lambs (150 days of age, 20.75 kg ± 1.33 kg body weight) were assigned to a rando...
Produção de biogás a partir de biomassas lignocelulósicas sorgo e capim-elefante.
O Brasil se destaca como um grande produtor agropecuário no cenário mundial. O setor do agro tem como contribuir muito com o desenvolvimento social e econômico, com um grande desafio de alcançar excelência no que se refere ao meio ambiente. O processo de biodigestão é uma forma de dar uma destinação adequada aos resíduos gerados na agropecuária ou ...
Caracterização química de genótipos de capim-elefante.
Simulation and risk analysis of the use of elephant grass silage cultibrate BRS Capiaçú compared to corn silage for dair...
Given the high production of dry matter that can be obtained by the cultivar BRS Capiaçu compared to corn for silage, there is a great economy of area used. with the BRS Capiaçu cultivar, in addition to its perenniality. Even when ensiled with corn meal, the silage of the BRS Capiaçú cultivar remains competitive in relation to corn silage, and can ...
Effects of thermotherapy and meristem culture on forage production and nutrition value in elephant grass cultivars.
Elephant grass plays important role in dairy cattle production and has received special attention due to its potential in bioenergy and phytoremediation, as well as to its medicinal properties. The aim was investigating the effects of thermotherapy and meristem culture on elephant grass (Cenchrus purpureus (Schumach.) Morrone) forage production and...
Estimation of repeatability and genotypic superiority of elephant grass half-sib families for energy purposes using mixe...
...
The mixed-model methodology is an alternative to select genotypes for traits highly influenced by the environment. In addition, this method allows FOR estimating the repeatability coefficient and predicting the number of assessments needed for a selection process to increase reliability. This study aimed to determine the minimum number of evaluatio...
