“…The median values obtained for the ammoniacal nitrogen variable in relation to the total nitrogen varied from 29.5 to 33.5 g.kg −1 total nitrogen (TN), which are lower than the average values reported by Pinto et al (2007) [20] and by Velho et al (2007) [17] of 58 and 41 g.kg −1 TN, respectively, for corn silage and similar to those reported by Santos et al (2010) [21], with a mean of 29 g.kg −1 TN. The ammoniacal nitrogen quantity varies in relation to the position in the feed-out face (core, lateral, and apical parts) of the silage and the ensiling procedure [22].…”

“…The ammoniacal nitrogen quantity varies in relation to the position in the feed-out face (core, lateral, and apical parts) of the silage and the ensiling procedure [22]. This variable is indicative of the degradation of protein in the fermentation phase of silage formation, which is one of the most important parameters for determining the quality of fermentation [21] and should be below 10% in quality silage [23]. Therefore, the results obtained for the ammoniacal nitrogen variable in the present study are indicative of the quality of the forage corn silage samples analyzed.…”

Does compaction degree and particle size influence bromatological composition and mycotoxin levels in corn silage?

et al. 2020

The objective of this study was to evaluate the effects of compaction degree and particle size on the presence of mycotoxins and the bromatological composition of corn silages. Samples from 47 silos with forage corn silage were collected from the northern region of Paraná State, Brazil. The bromatological composition and concentration of mycotoxin in silages were analyzed according to both the compaction degree (600 kg.m-3 and 700 kg.m-3) and particle size. Mycotoxins were detected using enzyme-linked immunosorbent assay, and test results were considered positive when the mycotoxin concentration was above the detection limit of 100 µg.kg-1 for deoxynivalenol, 2.5 µg.kg-1 for aflatoxin, 5 µg.kg-1 for zearalenone, and 200 µg.kg-1 for fumonisin. Silages with 600 kg.m-3 compaction degree had higher initial and final pH than silages with a higher compaction degree. Silage with a mean particle size less than or equal to 14.56 mm had 12% higher dry matter content than silage with a mean particle size more than 14.56 mm. There was no effect of the compaction degree or particle size on the concentration of mycotoxin, and 83% of the analyzed samples had contamination above the detection limits according to at least one of the studied mycotoxins. Silages with smaller average particle sizes had higher dry matter content. Thus, the degree of compaction and particle size did not affect the presence of mycotoxins in corn silage

“…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.…”

Fertilization with liquid swine manure increases productivity and improves the quality of Urochloa decumbens

et al. 2019

View full text Add to dashboard Cite

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.

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 ...
