This study aimed to isolate, characterize, and identify acetic acid-producing lactic acid bacteria from fresh sorghum plants silage, evaluate the effect of isolates as microbial inoculants on taxonomic diversity silage fermentation quality. For first experimental stage, eight silos were prepared, plant cv. BRS Ponta Negra (Sorghum bicolor (L.) Moench.) was sampled characterize bacteria. Five strains chosen be inoculated in second a 7 × 2 factorial design, with seven treatments two opening...
The objective of this experiment was to evaluate the effects adding cassava scrapings on gas and effluent losses, dry matter recovery, pH, contents N-NH3, organic acids volatile fatty bromatological composition elephant grass silages. It used a randomized complete design, with four levels (0, 7, 15 or 30% natural matter) each one replications per level. cut at 50 days regrowth ensiled in 15-L silos, equipped Bunsen valve allow outflow. losses decreased quadratically addition scrapings,...
Abstract The present study aimed to evaluate the chemical composition, profile and fermentative losses, microbial population aerobic stability of mixed silages cactus pear gliricidia. treatments corresponded addition levels gliricidia ( Gliricidia sepium (Jacq.) Steud), in Opuntia ficus indica Mill.), at ratios 0%, 25%, 50%, 75% 100% data were subjected analysis variance regression effect average related opening days compared by Tukey’s test hours exposure air Student’s t-test. silage...
Abstract This study aimed to evaluate the effects of forage neutral detergent fiber ( fNDF ) levels on voluntary feed intake, digestibility, ruminal fermentation and feeding behavior goats fed diets with cactus pear. Five non‐lactating ruminally cannulated ad libitum were randomly assigned a 5 × Latin square design. Treatments consisted at 0, 109, 222, 339 463 g/kg dry matter DM in pear‐based diets. The intakes NDF quadratically affected p ≦ .045) by levels. Voluntary water intake VWI...
Abstract The current study aimed to select the strains of lactic acid bacteria (LAB) isolated from forage cactus plants and silage assess their effects on fermentation aerobic stability. Forty wild isolates plant silage, classified as LAB, were evaluated for metabolite production identified by 16S ribosomal DNA sequencing. These Lactobacillus plantarum , Weissella cibaria confusa paramesenteroides LAB populations differed among silage. use microbial inoculants did not influence gas or...
The aim was to evaluate the chemical composition, carbohydrates, protein fractionation and in vitro gas production of silages composed spineless cactus tropical forages their effect on sheep performance. Treatments consisted silages: corn silage (CS), (SCS), + gliricidia (SCG), buffel grass (SCBG) pornunça (SCP). Silos were opened 60 days after ensiling, analyses carried out. digestibility test lasted for 36 days, with eight animals per treatment. A completely randomized design adopted....
The aim of this study was to evaluate the intake, digestibility, water balance and growth performance lambs receiving diets containing cactus silage under an intermittent supply. Thirty-six male, uncastrated Santa Inês with initial weight 19.8 ± 2.1 kg age 6 months were distributed in a 3 × factorial arrangement, three proportions pear (0 (control diet Tifton hay), 21% 42% dry matter) periods supply (0, 24 48 h), four repetitions. Lambs that received non-isonitrogenous showed higher intakes...
Silicon (Si) nanoparticles can attenuate nutritional disorders caused by phosphorus in forages through homeostasis. This paper aims to evaluate the effects of P deficiency and toxicity Megathyrsus maximus cultivated two types soils verify whether Si application via fertigation mitigate these imbalances. The following experiments were carried out: cultivation forage plants pots with Entisol Oxisol, a 3 × 2 factorial design, three levels (deficient, adequate, excessive) concentrations...
Nitrogen (N) holds a prominent position in the metabolic system of plants, as it is main constituent amino acids, which are basic building blocks proteins and enzymes. Plants primarily absorb N form ammonium (NH4+) nitrate (NO3−). However, most plants exhibit severe toxicity symptoms when exposed to NH4+ sole source. Addressing stress requires effective strategies, use silicon (Si) has shown promising results. there lack underlying studies on impact C:N:P stoichiometric balance role Si these...
The current study aimed to evaluate the application effects of preactivated Lactobacillus buchneri and urea on fermentative characteristics, chemical composition aerobic stability in corn silages. design was completely randomized, a 6 × 5 factorial arrangement, with six types additive five opening times. treatments consisted silage; silage freeze-dried inoculant; inoculant +1.0% urea; activated urea, 1.0% urea. Populations lactic acid bacteria stabilized at 70th day, average values 8.91 9.15...
Cactus pear is used in large proportions diets for small ruminants semiarid regions. However, its exclusive use not recommended due to the low fiber and crude protein content high water mineral content, leading metabolic disorders, dry matter intake, weight loss. The of mixed cactus silage associated with fibrous sources seeks overcome deficits matter, protein, aiming improve nutritional quality that will be offered ruminants. Thus, gliricidia hay silages could represent an important...
ABSTRACT The objective of this study was to evaluate the effect a phytogenic additive on nutrient intake, diet digestibility, nitrogen balance, and ruminal parameters lambs. Four lambs with an average body weight 27.6 ± 2.9 kg were distributed in 4 × Latin square design fed basal composed 600 g DM/day corn silage 400 concentrate. supplemented no 0.0, 2.0, 4.0, 6.0 g/kg DM pepper. intake DM, crude protein (CP), organic matter (OM), neutral detergent fiber (NDF) g/day decreased linearly (P...
<title>Abstract</title> Inadequate nitrogen (N) fertilization management in pastures is common and can lead to N deficiency or excess, resulting physiological imbalances forage grasses across different regions of the world. Silicon (Si) fertigation a promising strategy mitigate these issues due its anti-stress properties. However, effects on morphogenic growth processes their influence nutritional value remain unclear. This study investigated detrimental low, adequate, excessive N-urea...

Utilizou-se delineamento blocos completos casualizados com repetições arranjo fatorial 2 × 3. As avaliações consistiram monitoramento mensal aparecimento morte perfilhos em touceiras parcela, sendo os novos classificados basilares aéreos. A altura 15 cm promoveu maior aparecimento, 1,46...
The use of animal manure has been studied increasingly in recent years due to the excess waste confinements, which generates great amounts excreta; and as a result worsening petroleum crisis, cost mineral fertilizing products increased. Thus, studies point out potential this improve biotic abiotic soil condition nutritional value forage. Substances ingested by animals that resist action gastric enzymes are enriched with large bacteria, other microorganisms substances form residual feces,...
