<b>Agronomic characteristics of sorghum genotypes and nutritional values of silage

Abstract

The objective was to assess agronomic characteristics of sorghum genotypes and nutritional values of produced silage. A total of 15 sorghum genotypes were used. Planting was carried out through a randomized-block design with three replications per genotype, totaling forty-five (45) plots. Agronomic and nutritional characteristics, besides the quality of the silage, were assessed. There were differences between genotypes for all characteristics analyzed, with the exception of levels of acid detergent unavailable nitrogen (ADUN), acid detergent unavailable protein (ADUP) and water activity (aw). The assessment of the parameters, except for genotypes 1016013, 1016025, 1016037, 1016039, Volumax and BRS 610, which presented protein level below 7%, showed that the other genotypes can be used for silage production, since they have a good profile of fermentation and in vitro dry matter digestibility; however, genotype SF15 is the most favorable one for silage production due to its little participation in the neutral detergent fiber fraction.

Isolation and identification of lactic acid bacteria in fresh plants and in silage from Opuntia and their effects on the fermentation and aerobic stability of silage

“…The NH 3 -NT content is related to proteolysis, which occurs during the fermentation process and results from the growth of undesirable microorganisms, such as clostridia and enterobacteria (Muck, 2010). Costa et al (2016) state that well-fermented silage should present NH 3 -NT contents <100 g/kg of total nitrogen. Opuntia silage can, therefore, be considered to have an adequate fermentation profile since the NH 3 -N/NT contents were in the range of 0.99-2.63 g/kg.…”

Fermentation profile, microbial populations, taxonomic diversity and aerobic stability of total mixed ration silages based on Cactus and Gliricidia

“…Additionally, the proportions of NH 3 in relation to total nitrogen ranged from 0.041 to 0.055. Costa et al (2016) stated that well-fermented silages should provide N-NH 3 levels below 100 g/kg of total nitrogen. Regarding the crude protein values, the silages showed adequate values for a diet that reaches the requirements for lambs, as indicated by the NRC (2007), which recommends around 130 g/kg of CP for 200 g live weight gain per day.…”

Endophytic Fungi from Sorghum bicolor (L.) Moench: Influence of Genotypes and Crop Systems and Evaluation of Antimicrobial Activity

“…Characteristics of plant host are also important features that influence endophytic community composition. S. bicolor (L.) Moench is a well-known crop and its rusticity, high biomass production and great tolerance to water deficit are often mentioned [27]. By the other hand, research about how sorghum genotype influences in its endophytic community composition are scarce.…”

“…Qualimax genotype is a hybrid obtained by the crossing of saccharine and dry stems varieties and when compared to others sorghum genotypes it is considered superior due to its high adaptability to regions of harsh climate [27]. The results stand out Aspergillus spp.…”
