Minerals and potentially toxic elements in corn silage from tropical and subtro...
Motta,Antonio Carlos Vargas; Araujo,Eloá Moura; Broadley,Martin R.; Young,Scott D.; Barbosa,Julierme Zimmer; Prior,Stephen A.; Schmidt,PatrickABSTRACT Our aim was to assess the mineral composition of corn silages produced in four states of Brazil: Goiás, Minas Gerais, Paraná, and Santa Catarina. In total, seventy-three samples were analyzed. Total element content was extracted by HNO3 and H2O2 microwave-assisted digestion, and inductively coupled plasma-mass spectrometry (ICP-MS) was used to determine concentration. Of the 31 elements analyzed (Ag, A...
Natamycin as a potential silage additive: A lab trial using sugarcane to assess...
Bueno,Antonio Vinicius Iank; Vigne,Gabriela Letícia Delai; Novinski,Charles Ortiz; Bayer,Cimélio; Jobim,Clóves Cabreira; Schmidt,PatrickABSTRACT The objective of this study was to evaluate natamycin, Lactobacillus buchneri (LB), or their combination on the chemical composition, loss, fermentative profile, and aerobic stability as well as gas production and composition of sugarcane silages. The treatments were (wet basis): no additive (control), 10 g t−1 of natamycin (N10), 5 × 104 cfu g−1 of LB, and the combination of 4 g t−1 of natamycin and 2...
Effects of Lactobacillus buchneri on the nutritive value of sugarcane silage fo...
Schmidt,Patrick; Nussio,Luiz Gustavo; Queiroz,Oscar Cézar Müller; Santos,Mateus Castilho; Zopollatto,Maity; Toledo Filho,Sérgio Gil deLactobacillus buchneri 40788 and the fibrolytic enzymes β-glucanase and xylanase were applied to chopped sugarcane to study their effects on the nutritive value of silage. Sugarcane was mechanically harvested after 14 mo of growth and treated without (control) or with L. buchneri at a theoretical application rate of 5 × 10(4) cfu/g, 1 × 10(5) cfu/g, or 1 × 10(5) cfu/g plus enzymes. Forage was packed into farm-s...
Methods of lab silos sealing and fermentation characteristics and aerobic stabi...
Novinski,Charles Ortiz; Junges,Daniel; Schmidt,Patrick; Rossi Junior,Paulo; Carvalho,João Paulo Gomes de; Teixeira,Rodrigo de AlmeidaThe present experimental assay evaluated the effect of lab silo sealing methods on the ensilage of the sugarcane, with or without microbial additives (Lactobacillus plantarum and Propionibacterium acidipropionici). Twenty-liter plastic buckets were used as experimental silos, which were sealed with either a polyethylene sheet (silo cover with a mesh size of 200 µm) or an appropriate plastic lid equipped with Bu...
Voluntary intake of dry matter and performance of Nellore cows and their Nellor...
Vargas Junior,Fernando Miranda de; Wechsler,Francisco Stefano; Rossi,Patrícia; Oliveira,Marcus Vinicius Morais de; Schmidt,PatrickThis study aimed to investigate the influence of calf genetic group on the performance of Nellore lactating cows. The variables studied included milk ingestion, pasture intake, calf weight gain and cow body weight. A total of 13 Nellore calves and 8 crossbred Simental × Nellore calves were used, all born from Nellore mothers. During the experimental period of 210 days, calves were weighted at birth and at 30-da...
Influence of corn processing provided in the diet on the ruminal dynamics of da...
Vargas Junior,Fernando Miranda de; Sanchez,Luis Maria Bonnecarrère; Wechsler,Francisco Stefano; Bianchini,Waldmaryan; Oliveira,Marcus Vinicius Morais deThe objective of the present study was to evaluate the ruminal dynamics of dairy steer fed diets containing whole corn grains, grains ground into grits or whole grain treated with urea. Thus, six rumen-fistulated animals were kept in confinement and fed diets with similar contents of energy and protein. The diet was formulated with 40:60 roughage:concentrate ratio in the dry matter using sorghum silage as rough...
Novos aditivos microbianos na ensilagem da cana-de-açúcar: composição bromatoló...
Schmidt,Patrick; Rossi Junior,Paulo; Junges,Daniel; Dias,Laila Talarico; Almeida,Rodrigo de; Mari,Lucas JoséNesta pesquisa, comparou-se a inclusão de aditivo composto por cepas de Lactobacillus brevis + Enterococcus faecium + L. plantarum à inoculação com aditivo comercial contendo cepas de Lactobacillus buchneri e à ensilagem sem aditivos (controle). As silagens foram confeccionadas em silos experimentais e armazenadas por 90 dias antes da abertura do silo. Foram avaliadas a composição bromatológica da cana-de-açúca...
Ingestive behavior of Nellore cows and their straightbred or crossbred calves
Vargas Junior,Fernando Miranda de; Wechsler,Francisco Stefano; Rossi,Patrícia; Oliveira,Marcus Vinicius Morais de; Schmidt,PatrickThis trial aimed to investigate the influence of calf genetic group on the ingestive behavior of Nellore dams and their offspring on pasture. Twenty one primiparous and multiparous Nellore cows were assigned to the experiment; 13 cows nursed straightbred Nellore calves; and eight cows nursed halfbred Simmental × Nellore calves. The observations started in the morning, as soon as identification of the animals in...
Perdas fermentativas e composição bromatológica da entrecasca de palmito pupunh...
Schmidt,Patrick; Rossi Junior,Paulo; Toledo,Luciandra Macedo de; Nussio,Luiz Gustavo; Albuquerque,Danila Santiago de; Meduri,BeatrizObjetivou-se avaliar o efeito da inclusão de aditivos químicos na ensilagem de resíduos (entrecasca) da produção de palmito pupunha (Bactris gasipaes, Kunth). Utilizaram-se silos experimentais (baldes de 20 litros) providos de aparatos para determinação gravimétrica de perdas por gases e efluentes. Os tratamentos aplicados foram: controle (sem aditivos); ureia (1% da MV) e cal virgem (1% da MV). Decorridos 70 d...
Nutritive value of sugarcane silage treated with chemical additives
Santos,Mateus Castilho; Nussio,Luiz Gustavo; Mourão,Gerson Barreto; Schmidt,Patrick; Mari,Lucas José; Ribeiro,José Leonardo; Queiroz,Oscar Cézar MüllerThe use of ensiled sugarcane has been increased lately in Brazil due to the benefits that this technique represents. The objective of this study was to evaluate the effects of chemical additives on the nutritive value of sugarcane silages. The trial was carried out in a completely randomized experimental design with four replicates per treatment. The following additives were applied onto the fresh forage before...
