Santos,Andréia de Oliveira dos; Dias Junior,Gilson Sebastião; Pereira,Marcos Neves; Schwan,Rosane Freitas; Ávila,Carla Luiza da Silva.
ABSTRACT Whole-plant corn silage (WPCS) is a commonly used forage for feeding dairy cattle in Brazil. The aim of this study was to evaluate on-farm ensilaging practices and the nutritional value, microbiology and fermentation profiles of WPCS from dairy farms in the south of the state of Minas Gerais, Brazil. Silages from 54 dairy farms located in nine cities were sampled and a questionnaire was distributed for completion to describe the herd profile and ensilage practices. Herd size ranged from 8 to 1,000 lactating cows, and 52 % of the farms had fewer than 50 cows in lactation. The majority of the farms cultivated hard endosperm texture hybrids (52 %) and used pull-type forage harvesters (87 %). Double-sided plastic was the most used form of silo...

Aerobic deterioration influences the fermentative, microbiological and nutritional quality of maize and sorghum silages on farm in high quality milk and cheese production chains R. Bras. Zootec.
Borreani,Giorgio; Bernardes,Thiago Fernandes; Tabacco,Ernesto.
Maize and sorghum silages are good sources of energy for lactating dairy cows that produce milk destined for fresh and matured cheeses. Silages are usually stored in horizontal silos with or without side walls on commercial farms throughout the world. The main microbiological and nutritional quality problems are related to harvesting time, ensiling technology, and management practices during filling and feed-out. Aerobic deterioration is a key point that must avoided on farms in order to improve the hygienic, chemical and sensorial quality of milk and cheeses. Aerobic deterioration causes large losses of dry matter (DM) and quality, and it can cause health problems for animals and humans through the transfer of pathogens and mycotoxins from feed and...

Bumbieris Junior,Valter Harry; Jobim,Clóves Cabreira; Emile,Jean-Claude; Roman,Juliano; Silva,Michele Simili da.
The objective of the present study was to evaluate the aerobic stability and losses during the fermentation process of triticale silages in single crop or in mixtures with oats and/or legumes. The following crops were used for silage production: triticale (X. Triticosecale Wittimack), triticale intercropped with forage pea (Pisum arvense) and triticale intercropped with oats (Avena strigosa Schreb), forage pea and vetch (Vicia sativa). The dry matter content and its recovery did not differ among the silages. Buffer capacity was higher for tricale silage intercropped with oats, forage pea and vetch(88.67 m eq. NaOH/100 g DM) followed by triticale intercropped with forage pea (80.80 m eq. NaOH/100 g DM). Electric conductivity values were higher in the...

Coelho,Mateus Merlo; Gonçalves,Lúcio Carlos; Rodrigues,José Avelino Santos; Keller,Kelly Moura; Anjos,Gustavo Vinícius de Souza dos; Ottoni,Daniel; Michel,Pedro Henrique Fulgêncio; Jayme,Diogo Gonzaga.
Abstract: The objective of this work was to evaluate the effects of re-ensiling and bacterial inoculation on the quality of corn silage. The experiment was carried out in a 2x2 factorial design with or without inoculant (association of Lactobacillus plantarum and Propionibacterium acidipropionici), and with re-ensiling after 36 hours of aerobic exposure or only ensiling of the whole plant of 'BRS 1055' corn. The fermentative quality, nutritional parameters, dry matter losses, aerobic stability, and microbiological counts of silages were evaluated. Re-ensiling caused an increase of pH and in acetic acid and propionic acid concentrations, as well as in the dry matter (DM), crude protein, neutral detergent fiber, and neutral detergent fiber crude protein...

Fermentation and aerobic stability of high-moisture corn silages inoculated with different levels of Lactobacillus buchneri R. Bras. Zootec.
Basso,Fernanda Carvalho; Bernardes,Thiago Fernandes; Roth,Anna Paula de Toledo Piza; Rabelo,Carlos Henrique Silveira; Ruggieri,Ana Cláudia; Reis,Ricardo Andrade.
Fermentation and aerobic stability were evaluated in high-moisture corn (HMC) silage inoculated with different levels of Lactobacillus buchneri. The HMC composed of 654 g/kg dry matter (DM) was ensiled in quadruplicate laboratory silos (7 L) per treatment. L. buchneri 40788 was applied at 5 × 10(4); 1 × 10(5); 5 × 10(5); and 1 × 10(6) cfu/g to the ground corn. Silages with no additive were used as controls. After 140 d of ensiling, the silages were subjected to an aerobic stability evaluation for 12 days in which the chemical parameters, microbiological parameters and silage temperature were measured to determine the aerobic deterioration. The lactic acid, acetic acid and propionic acid concentrations did not differ between silages. The fermentation...

Nutritive value of corn silage from intensive dairy farms in Brazil R. Bras. Zootec.
de Oliveira,Isabella Lasmar; Lima,Luciana Miranda; Casagrande,Daniel Rume; Lara,Márcio André Stefanelli; Bernardes,Thiago Fernandes.
ABSTRACT The objective of this research was to characterize the nutritive value of corn silage made on intensive dairy farms and demonstrate the nutritional variations between silages located at the top and at the center of a bunker silo. Thirty-two dairy farms were visited in four Brazilian states. One corn bunker silo of each farm was chosen and samples were collected from the top and center parts. The nutritive value, fermentation end-products, and microbial counts were assessed. The predicted milk was determined by Milk2006 spreadsheet. The mean, standard deviation, maximum, minimum, and 95% confidence interval of all data were calculated. The ash, neutral detergent fiber (NDF), starch, in vitro NDF, and dry matter (DM) digestibility data were compared...

Sealing type effect on corn silage quality in bunker silos Ciência Rural
Neumann,Mikael; Leão,Guilherme Fernando Mattos; Askel,Eloize Jaqueline; Marafon,Fabiano; Figueira,Danúbia Nogueira; Poczynek,Mailson.
ABSTRACT: Forage conservation in silos depends on the efficiency of silo sealing, among other factors, to minimize aerobic deterioration and consequent qualitative and quantitative losses in silage. Thus, the aim of the present study was to evaluate the effect of two sealing types on dry matter recovery rate, aerobic stability, nutritional composition, and in vitro digestibility of corn silage in bunker silos: 110-µm-thick double-sided polyethylene sealing (conventional sealing) and110-µm-thick double-sided polyethylene sealing superimposed on 111-µm-thick translucent polyethylene sealing (double sealing). There were no significant differences in nutritional composition of silages between conventional and double sealing. However, the double sealing system...

Bueno,Antonio Vinicius Iank; Jobim,Clóves Cabreira; Rossi,Robson Marcelo; Gritti,Viviane Carnaval; Leão,Guilherme Fernando Mattos; Tres,Tamara Tais.
ABSTRACT We aimed to evaluate the effects of glyphosate as a chemical desiccant on the nutritional quality, fermentation pattern, and aerobic stability of wilted black oat (Avena strigosa Schreb) silage. Black oat sowing occurred in the first fortnight of May 2013. Desiccant application took place when oat reached milky/dough grain stage (96 days after planting). Glyphosate dosages evaluated were 0, 500, 750, 1000, and 1250 mL ha−1. Three days after desiccation, all treatments were ensiled, and the silos were kept stored for 150 days. A completely randomized design was used, and all statistical procedures were performed by means of Bayesian Inference. Treating herbage prior to ensiling from 500 mL ha−1 glyphosate increased dry matter and organic matter...
