Zeolite supplementation effects on lamb growth and gastrointestinal nematode in...
Esteves,Sérgio Novita; Chagas,Ana Carolina de Souza; Oliveira,Márcia Cristina de Sena; Barioni Júnior,Waldomiro; Bernardi,Alberto C. de CamposABSTRACT Zeolite as a dietary supplement can improve animal resistance and resilience against gastrointestinal parasites. The effects of different levels of zeolite supplementation on gastrointestinal nematode infection, growth performance, and economic viability of male and female Santa Ines lambs were investigated. Four zeolite levels (0, 25, 50, and 75 g per day) were fed to 110 day-old animals in a randomiz...
In vivo study of a homeopathic medicine against Rhipicephalus (Boophilus) micro...
Figueiredo,Amanda; Fantatto,Rafaela Regina; Agnolon,Isabela Cabeça; Lopes,Louyse Gabrielli; Oliveira,Patrícia Rosa de; Mathias,Maria Izabel CamargoABSTRACT The tick Rhipicephalus (Boophilus) microplus (Canestrini, 1887) (Acari: Ixodidae) causes large economic losses to cattle breeders and its control is hampered by problems of resistance to the main commercial synthetic acaricides and the risk of residues in animal products. Alternative controls are important for the sustainability of cattle breeding in tropical regions, principally for organic milk produ...
Relationship between virulence factor genes in coagulase-negative Staphylococcu...
Zafalon,Luiz F.; Cunha,Maria L.R.S.; Brandão,Humberto M.; Mosqueira,Vanessa C.F.; Santana,Raul C.M.; Barioni Júnior,Waldomiro; Martins,Katheryne B.ABSTRACT: Coagulase-negative Staphylococcus spp. (CNS) are the main microorganisms involved in ovine mastitis. Treatment at the end of lactation can contribute towards cure and prevention of subclinical cases during the subsequent lactation. However, virulence factors and resistance mechanisms presented by CNS can decrease cure rates. The aims of the study were to identify the species of CNS in milk of mastitic...
GROWTH OF NATIVE TREES IN TWO AGROFORESTRY SYSTEMS
Nicodemo,Maria Luiza Franceschi; Muller,Marcelo Dias; Porfírio-da-Silva,Vanderley; Carpanezzi,Antônio Aparecido; Pezzopane,José Ricardo MacedoABSTRACT Agroforestry systems with eucalyptus prevail in Central and Southeast Brazil, and little information is available about systems using native trees. The aim of the present study was to evaluate the development of seven native tree species grown under two agroforestry systems. The experiment was conducted starting in 2007 in 12-hectare area in the municipality of São Carlos, São Paulo state, Brazil. The ...
ESTABLISHMENT TECHNIQUES FOR TROPICAL LEGUMES IN THE UNDERSTORY OF A EUCALYPTUS...
Nicodemo,Maria Luiza Franceschi; Souza,Francisco Humberto Dubbern de; Pezzopane,Jose Ricardo Macedo; Mendes,João Carlos TeixeiraThis study evaluated establishment methods for a mixture of herbaceous forage legumes [Centrosema acutifolium, Clitoria ternatea, Pueraria phaseoloides, Stylosanthes Campo Grande (Stylosanthes capitata + S. macrocephala), Calopogonium mucunoides, Lablab purpureus, Arachis pintoi, and Aeschynomene villosa] under the shade of an Eucalyptus grandis plantation submitted to thinning (40%) 8 years after planting in A...
Evaluation of sugarcane laboratory ensiling and analysis techniques
Pedroso,André de Faria; Pedroso,Alexandre Mendonça; Barioni Júnior,Waldomiro; Souza,Gilberto Batista deThe objective was to evaluate the effects of laboratory-silo type and method of silage extract production, respectively, on sugarcane silage fermentation and recovery of fermentation products. Sugarcane was mechanically harvested and ensiled in three different types of laboratory silos (five replicates): 9.7 × 30 cm PVC tubes with tight lids, equipped or unequipped with Bunsen valves, and 20 L plastic buckets w...
New methods to quantify NH3 volatilization from fertilized surface soil with urea
Alves,Ana Carolina; Oliveira,Patrícia Perondi Anchão; Herling,Valdo Rodrigues; Trivelin,Paulo Cesar Ocheuze; Luz,Pedro Henrique de CerqueiraGaseous N losses from soil are considerable, resulting mostly from ammonia volatilization linked to agricultural activities such as pasture fertilization. The use of simple and accessible measurement methods of such losses is fundamental in the evaluation of the N cycle in agricultural systems. The purpose of this study was to evaluate quantification methods of NH3 volatilization from fertilized surface soil wi...
Fermentation parameters, quality and losses in sugarcane silages treated with c...
Pedroso,André de Faria; Rodrigues,Armando de Andrade; Barioni Júnior,Waldomiro; Souza,Gilberto Batista deThe objective of this trial was to evaluate chemical additives and a bacterial inoculant on the inhibition of alcoholic fermentation and reduction of losses in sugarcane silages. Treatments were (doses on a fresh forage basis): without additive (control); urea (10 g/kg); urea (5 g/kg) + sodium benzoate (0.5 g/kg); sodium benzoate (1 g/kg); urea + ammonium sulfate in a 9:1 relation (10 g/kg); Lactobacillus buchn...
Aditivos químicos e inoculante bacteriano na ensilagem de cana-de-açúcar: efeit...
Pedroso,André de Faria; Rodrigues,Armando de Andrade; Barioni Júnior,Waldomiro; Barbosa,Pedro Franklin; Santos,Flávio Augusto PortelaOs objetivos neste experimento foram avaliar o desempenho de tourinhos alimentados com rações completas preparadas com silagens de cana-de-açúcar tratadas ou não com aditivos e estudar o efeito dos aditivos sobre a fermentação das silagens. Trinta tourinhos Canchim com peso médio de 312 kg foram distribuídos em delineamento de blocos casualizados para avaliar três tipos de rações isoproteicas e isoenergéticas (...
Determinação do coeficiente de repetibilidade e estabilização genotípica das ca...
Ferreira,Reinaldo de Paula; Vasconcelos,Edmar Soares de; Cruz,Cosme Damião; Barioni Júnior,Waldomiro; Rassini,Joaquim BartolomeuForam estimados os coeficientes de repetibilidade das características de produção de matéria seca (PMS), altura das plantas no momento do corte (APC), tolerância a doenças (TD) e altura no florescimento (AF), em genótipos de alfafa. As características foram avaliadas em 92 genótipos nos anos 2004 e 2005, durante 11 cortes, feitos nos períodos das águas (novembro a março, cinco cortes) e da seca (abril a setembr...
