“…Different from protein levels, low levels of NDF are desirable and indicate high nutritional quality of the forage, because according to Sandahl et al (2005), the NDF content of a forage plant was consolidated as the bromatological component more closely related to their potential intake by ruminants. Thus, the lower the levels of this component, the better the quality of the forage produced and the greater the consumption of MS (SANTOS et al, 2010). In this sense, smaller doses of LSM provided the forage with best quality.…”

This study aims at assessing the influence of mineral fertilization and biofertilizer from liquid swine manure (LSM) in productivity, levels of crude protein (CP), neutral detergent fiber (NDF) and Acid Detergent Fiber (ADF) of Urochloa decumbens. The experiment was carried out in a red Latosol under a Urochloa decumbens pasture, in a state of degradation with loss of vigor and forage productivity. The delineation chosen for this study was randomized blocks with six treatments (control without fertilization, control with use of mineral fertilizer and four unique concentrations of liquid swine manure biofertilizer (61 m3 ha-1, 121 m3 ha-1, 181 m3 ha-1, 241 m3 ha-1)). The application of residue has been split in two times on the surface of the soil, by means of a distributor of liquid waste with a fan-shaped application. Yield and bromatological features were evaluated for two years. Fertilization with LSM can fully replace mineral fertilizing in Urochloa decumbens pasture systems, resulting in an increase, as a result, in the dry mass yield from the dosage of 121 m3 ha-1 and the reduction in fiber content in neutral and acid detergent. The increments in yield were observed in the second year, while improvement in bromatological quality was observed from the first application of LSM.

“…Portanto, esse parâmetro é um dos mais importantes na determinação da qualidade do processo fermentativo da massa ensilada (sAnTos et al, 2010). No presente estudo, verificou-se efeito quadrático para os valores de N-NH 3 (P=0,032) (Figura 4), com variação de O volume do efluente produzido em um silo é influenciado, principalmente, pelo conteúdo de matéria seca da espécie forrageira ensilada e o grau de compactação, além de outros, tais como: tipo de silo, pré-tratamento mecânico da forragem, dinâmica de fermentação e fertilização do solo que tem influência direta sobre o desenvolvimento da cultura e, em conseqüência, sobre a percentagem de matéria seca (WooLFord, 1984).…”

RESUMO: Objetivou-se investigar as características fermentativas e nutricionais da rama da batata doce (Ipomoea batatas) na forma de silagem utilizando níveis de fubá de milho como aditivo. O delineamento experimental utilizado foi inteiramente casualizado com sete níveis de aditivo (fubá de milho) (0; 5; 10; 15; 20; 25 e 30%) e quatro repetições, totalizando 28 mini silos laboratoriais (unidades experimentais). Efeito quadrático foi observado nos teores de matéria seca (MS), proteína bruta (PB), proteína insolúvel em detergente neutro (PIDN), proteína insolúvel em detergente ácido (PIDA) e carboidratos totais das silagens da rama da batata doce com diferentes níveis de aditivo. Houve aumento no teor de MS com adição do aditivo, e a PB reduziu de 11,23% (zero aditivo) para 9,46% (30% aditivo) nas silagens da rama da batata doce. Os teores da PIDN e PIDA foram menores das silagens da rama da batata com 30% de aditivo (1,15% e 0,70%, respectivamente). Não foi observada diferença significativa nos teores de matéria orgânica, cinzas, extrato etéreo, fibra em detergente ácido, fibra em detergente neutro e nutrientes digestíveis totais nas silagens da rama da batata doce em relação aos níveis de aditivos. Na avaliação dos parâmetros fermentativos, foi observado efeito quadrático no pH, nitrogênio amoniacal, em porcentagem do nitrogênio total [N-NH 3 (%NT)], perda por gases e perda por efluentes das silagens da rama da batata doce com diferentes níveis de aditivo. Menor valor de pH foi observado no nível de 15% de aditivo (3,31) e maiores nos níveis 20%, 25% e 30% de aditivo (3,88; 3,89 e 3,88, respectivamente). Os valores de N-NH 3 (%NT) variaram de 2,84% (zero aditivo) a 3,59% (15% aditivo), e a menor perda por gases e efluentes foi de 2,38% MS e 199 kg/t nas silagens da rama da batata doce com 30% e 10%de aditivo, respectivamente. A rama da batata doce representa um volumoso alternativo de boa qualidade que pode ser armazenado na forma de silagem, desde que se utilize aditivo absorvente de umidade, como o fubá de milho, em nível não inferior a 20%.Palavras-chave: carboidratos totais, efluente, gases, nitrogênio amoniacal, pH. CHARACTERIZATION OF SILAGE MADE FROM SWEET POTATO VINES USING CORN MEAL AS ADDITIVEABSTRACT: The objective of this study was to investigate the fermentative and nutritional characteristics of sweet potato (Ipomoea batatas) vine silage using different levels of corn meal as additive. A completely randomized design consisting of seven levels of the additive (0, 5, 10, 15, 20, 25 and 30% corn meal) and four replicates was used, totaling 28 laboratory mini-silos (experimental units). The different levels of additive in sweet potato vine silage exerted quadratic effects on the content of dry matter (DM), crude protein (CP), neutral detergent insoluble protein (NDIP), acid detergent insoluble protein (ADIP), and total carbohydrates. There was an increase in DM content with inclusion of the additive and CP was reduced from 11.23% (no additive) to 9.46% (30% additive) in sweet potato vine silage. NDIP ...

“…Rowghani et al (2008) observed, in inoculated corn silage, butyric and lactic acid values of 30.5 and 2.85 g/kg DM, respectively, whereas Filya et al (2004) found no butyric acid in silages treated with L. plantarum and P. acidipropionici, which presented concentrations of 1.2 g/kg DM alcohol and 66.0 g/kg DM lactic acid. According to Santos et al (2010), the butyric acid content reflects the extension of clostridia activity and is related to final higher pH levels. Concentrations below 3 g/kg DM indicate lower energy and dry matter losses (Tomich et al, 2003).…”

-The objective of this study was to evaluate the production practices and use of corn silage in dairy farms in Southern Brazil, and to evaluate their impact on the nutritional quality and occurrence of mycotoxins. The data were collected by application of questionnaires among the producers, and by analysis of silage samples. The variables were subjected to factorial analysis of data reduction through the principal components method, thus obtaining 84.12% of the variance associated with the location, corn hybrid, crop production management, and inoculant used, characterizing the farms into four distinct groups. In farms from Paraná, the silage production technologies were more associated with implantation and crop management processes, and investment in equipment related to ensilage/silo feed-out was less frequent. Farms of Rio Grande do Sul showed high adoption of outsourced services, self-propelled machines, bunker silos, double-sided plastic film, and inoculant to control aerobic deterioration, and the silages showed higher levels of propionic acid (7.95 g/kg DM), and lower concentrations of aflatoxins (7.7 ppb) and total mycotoxins (26.58 ppb). The farms evaluated in Southern Brazil have good production efficiency and corn silages with excellent quality, regardless of their production characteristics.
