1. Forage sources in diets for dairy goats
ABSTRACT. The objective of this study was to evaluate the use of sorghum silage, Buffel grass hay and forage palm fodder in the diet of dairy goats by means of performance tests and economic viability of different roughage sources. Eight Anglo-Nubian goats, multiparous, weighing around 40.13 ± 2.76 kg of live weight were used. The experiment lasted 84 days,

2. Influence of the storage environment on the physiological quality of millet seeds (Pennisetum glaucum (L.) R. Br.)
Resumo: O milheto é uma espécie da família das gramíneas, utilizada na produção de pastagens para bovinos, feno, silagem e na cobertura do solo em sistema de plantio direto. No entanto, estudos sobre produção de sementes e técnicas de pós-colheita para esta espécie são incipientes considerando-se a demanda e o potencial desta cultura. Diante diss

3. Performance and digestibility of confined lambs fed with Babassu cake (Orbignya speciosa) as a substitute for elephant grass silage
RESUMO Objetivou-se avaliar a substituição parcial da silagem de capim elefante por torta de babaçu (Orbignya speciosa) sobre o desempenho, consumo, digestibilidade, composição química e ganho em peso de carcaça de ovinos. Cinquenta e quatro machos, castrados (19,08±2,76kg) foram distribuídos em delineamento inteiramente casualizado e administrado u

4. Nutritive value of elephant grass silage added with cottonseed cake in diet for sheep
RESUMO Objetivou-se avaliar o consumo, digestibilidade dos nutrientes e balanço de nitrogênio em ovinos alimentados com rações contendo silagem de capim-elefante (Pennisetum purpureum Schum) contendo 0; 7; 14 e 21% de torta de algodão. Foram utilizados vinte ovinos Morada Nova em delineamento inteiramente casualizado com quatro tratamentos e cinco repet

5. Fermentative losses and chemical composition of elephant grass silage added with castor bean hull
RESUMO A fermentação e a composição química da silagem de capim-elefante foram avaliadas com 0; 10; 20 e 30% de casca de mamona com base na matéria natural.O delineamento experimental foi inteiramente casualizado com cinco repetições. Os silos foram pesados durante a confecção dos mesmos, sendo novamente pesados antes e após a abertura, depois de

6. Fatty acid profile in vertical strata of elephant grass subjected to intermittent stocking
ABSTRACT The milk and meat from animals with a pasture-based diet have higher proportions of CLA and C18:3 and lower omega-6:omega-3 ratios than products from animals with diets based on corn silage and concentrate. However, most of the published studies have evaluated fatty acid profiles in temperate climate grasses and the literature with tropical grasses

7. The use of crude glycerin as an alternative to reduce fermentation losses and enhance the nutritional value of Piatã grass silage
ABSTRACT The objective of this study was to evaluate fermentation losses and the nutritional value of silage of Brachiaria brizantha cv BRS Piatã ensiled with different levels of crude glycerin. The experiment followed a 4 × 2 completely randomized factorial design with four doses of crude glycerin (0, 100, 200, and 300 g kg–1 of DM silage) and two cutti

8. 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

9. ANAEROBIC MODELING FOR IMPROVING SYNERGY AND ROBUSTNESS OF A MANURE CO-DIGESTION PROCESS
Abstract Biogas production is becoming increasingly important in the environmental area because, besides treating wastewaters, it also generates energy. Co-digestion has become more and more powerful since it is possible, with the use of abundant and cheap substrates, to dilute the inhibitory effects of various other substrates, making the process of anaerob

10. Enhancing the analytical capacity for biogas development in Brazil: assessment of an original measurement system for low biogas flow rates out of agricultural biomass residues
ABSTRACT This study presents a comparison of two systems for measuring low-flow biogas production rates. Grass silage was used as substrate in the experiment. Measurements were made by using (a) manual readings and (b) an automated system. The automated system proved to be efficient as it allowed readings of the biogas flow rates in real time. Results were s

11. 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

12. 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
