Influence of homeopathy on the quality of quail eggs stored for different periods of time

The purpose of this trial was to assess the influence of homeopathy products on the diet of quails based on egg quality when submitted to different storage periods. Methodology: Two hundred, 45 day old Japanese quails and 80% of production were used, in a completely randomized design comprised of a 4x3 factorial, and 4 diets (basal feed, inert vehicle and 2 homeopathic products: Fertsigo® (Sulphur10 CH, Sepia 15CH ) and Ovosigo® (Belladonna 12CH,Silicea 12 CH, Natrum mur. 30CH, Calcarea phos. 30CH, Sulphur 12CH) and 3 storage periods (0 days, 7 days and 14 days) with ten repetitions of three eggs per treatment. The weight, percentages of yoke, albumen and shell, albumen height and yolk color, specific gravity, Haugh unit, yolk index and shell thickness were evaluated. The data were submitted to variance analysis to verify whether there was a interaction effect between homeopathy factors and storage time, and when absent, the isolated effects. Results: An interaction between the homeopathic products and time was found for the parameters of albumen height and yolk, Haugh unit and yolk index, which reduced over time. For egg weight, yolk, albumen and shell, a significant effect (p<0.05) was found only in the case of homeopathy for the percentages of albumen and shell. For egg and albumen weights, yolk and albumen percentages, specific gravity and colorimetry there was an effect for time, however these parameters reduced over the storage time in days. The addition of the homeopathic based products Ovosigo® and FertSigo® are indicated for the diets of Japanese quail during the laying phase since it resulted in better weights for the egg and its components. Conclusion: The different homeopathic products did not have an influence on conserving the quality of the Japanese quail eggs during the periods evaluated.

Effect of homeopathy on soybean germination through soil and seed treatment

Homeopathy is a technique approved by the MAPA for organic production systems. Experiments demonstrating the effectiveness of homeopathy in agriculture are essential. Aims: To evaluate the effects of homeopathic treatment on soybean seed germination. Methodology: The experiment was performed in MS-Brazil. An area of 70 m² was used, divided into two comparison plots of 30 m² each. The soil of plot 1 (treated group) was treated with 5.25 kg of powdered Lithothamniummixed with 250 ml of 30% hydroalcoholic solution (HS) containing homeopathic ingredients. The soil of plot 2 (control group) was treated with thesame preparationbutwithout homeopathic ingredients. Additionally, the 400 seeds assigned toplot 1 were treated with 0,3 ml of a solution made up of 10 ml of 30% HS with homeopathic ingredients dilutedin 300 ml of water. The 400 seeds assigned toplot 2 were treated with 0.3 ml of a solutionmade up of 10 ml of HS without homeopathic ingredients diluted in 300 ml of water. The homeopathic ingredients Sulph 9C, Mag-c12C, and Calc-p 9C were used on soil and seed treatment. The selection and prescription of those ingredients followed Materia Medica instructions. The experiment was conducted using randomized design and 400 seeds per group were sown. Results and discussion: In plot 1, anaverage of 11 seeds per m² germinated, adding up to 330 germinated seeds at a percentage of 82.5%. In plot 2, an average of 7 seeds per m² germinated, adding up to 210 germinated seeds at a percentage of 52.5%. The frequency of seed germinationin both groups was assessed by the Chi-square test to check for significant differences(p<0.05). There was a statistical difference (p<0.05) in the seed germination in the treated group (n=330) compared to the control group (n=210). Conclusion:Homeopathic compounds can be used as a viable treatment for soybean germination.

Effect of homeopathy on quality of corncobs naturally exposed to sugarcane virus

The use of pesticides is damaging to the health of farmers and consumers as their use is associated with numerous diseases. Homeopathy is one of the techniques for organic agriculture currentlyauthorized by the MAPA. Aims: To assess the effect of homeopathic compounds on corncob quality in pesticide-free cultures. Methodology:The experiment was performed in, MS-Brazil. Two culture fields were used, each 30m2in size. The homeopathic group treatment consisted of 1ml of30% hydroalcoholic solution with homeopathic ingredients. This solutionwas diluted into 30ml of water and then sprayed onto 100 seeds. The control group was submitted to the same protocol excluding the homeopathic ingredients. The homeopathic ingredients used were Sulph9C, Mag-c12C, and Calc-p9C, prescribed according to Materia Medica instructions. The evaluationwas performed at harvest by comparing theaverage weight of 1000 kernels pergroup, obtained from a weighingof 3000 kernels per group. In addition, a number of corncobs from both groups werequalitatively evaluated as "good" or "bad." Statistics analysis used the T-test to compare the kernel weight averages and Fisher's exact test to analyze the corncob quality frequency. Both groups were naturally infected by a virus from a neighboring sugarcane field, causing qualitative and quantitative losses on both groups. Results and discussion: The average weight of 1000 kernels from the treated group (329 g) was not significantly greater (p=0.06) than the average weight of 1000 kernels from the non-treated group (308 g). It was observed that 71out of 158 (44.9%) corncobs from the homeopathic treatment group were classified as "good" while zero outof 50 (0%) corncobs from the non-treated group were classified as "good", resulting in a significant difference (p<0.01). Conclusion: Homeopathic compounds can be used as a feasible treatment for health and productivity in the corn crop.

Control of Rhipicephalus microplusticks in dairy cattle using homeopathic therapy

The negative impact of Rhipicephalus microplusinfestations on cattle farming is well-known. The main control method is the use of ixodicides, which have as side effects environmental contamination, the selection of resistant lineages, and toxicity. Their use is also prohibited in systems that produce organic and agroecological food. Such factors reinforce the importance of strengthening researchrelated to the application of homeopathic principles in animal production. Aim: In this setting, this work aimed at assessing the efficacy of the homeopathic therapy to control Rhipicephalus microplusticks in dairy cattle. Methodology: 63 crossbred and Girolando breed cows, 1 and 9 years of age, naturally infested by ticks and created under a semi-intensive system in three farms (1, 2,and 3) were assayed. The animals were divided into three control groups and three treated groups, using the drug product EndectoSigo® (Psorinum12 CH, Sulphur 12CH, Ledum palustre12 CH, Cina12 CH e Apis mell.7CH) at a dose of 10 g/animal/day added to mineral and/or food supplement. The visual counting of teleogines with the size equal to or higher than four millimeters indiameter was performed in the neck or udder area of the animal. Pluviometry and registration of ixodicide baths were performed as well.The means obtained were compared by using ANOVA test and Tukey's test. Results: The mean number of teleogines on farm 1was significantly lower (p<0.05) in the treatment group. As for farms 2 and 3, there was no statistical difference between the groups (treated and control); however, it was observed that two ixodicide baths were required in the control group (farm 2). Thepluviometry did not interfere with the manifestation. Conclusion: It was concluded that the homeopathic treatment has the efficacy required to control this tick in cattle and can be an alternative to the use of chemical ixodicides.

Effects of platelet-rich plasma gel on skin healing in surgical wound in horses.

PURPOSE: To establish a low-cost method to prepare platelet-rich plasma (PRP) and evaluates the potential of platelet derived factors to enhance wound healing in the surgical wounds in equine. METHODS: To obtain a PRP gel, calcium gluconate and autologous thrombin were added to platelet-rich plasma. For the tests six saddle horses were used and two surgical incisions were made in each animal. Wounds were treated with PRP gel or untreated. Sequential wound biopsies collected at Treatment 1: at days 5 and 30 and Treatment 2: at days 15 and 45 post wounding permitted comparison of differentiation markers and wound repair. RESULTS: The optimal platelets enrichment over 4.0 time's baseline values was obtained using 300 g for 10 min on the first centrifugation and 640 g for 10 min on the second centrifugation. CONCLUSION: Wounds treated with PRP gel exhibit more rapid epithelial differentiation and enhanced organization of dermal collagen compared to controls in equine.

OBJETIVO: Estabelecer um método econômico na preparação de plasma rico em plaquetas (PRP) e avaliar se os fatores derivados destas plaquetas aceleram a cicatrização de feridas cirúrgicas em cavalos. MÉTODOS: Gluconato de cálcio e trombina autógena foram adicionados ao PRP para a obtenção do gel de PRP. Foram usados seis cavalos de sela, cada um dos quais sofreu duas incisões cirúrgicas. Uma destas incisões foi tratada com gel de PRP e a outra suturada de maneira tradicional (controle). A biópsia das feridas foi coletada de maneira seqüencial; Tratamento 1. nos dias 5 e 30 e Tratamento 2. nos dias 15 e 45 do período pós-operatório permitindo uma comparação na diferenciação epitelial e no reparo das feridas. RESULTADOS: O enriquecimento das plaquetas obtido através de uma primeira centrifugação usando 300 g por 10 minutos e uma segunda 640 g por 10 minutos acelerou quatro vezes a reparação tecidual em relação ao controle. CONCLUSÃO: As feridas tratadas com gel de PRP apresentaram uma mais rápida diferenciação epitelial e acelerou a organização do colágeno da derme comparado ao grupo controle em cavalos.

Steroidal saponin concentrations in Brachiaria decumbens and B. brizantha at different developmental stages / Concentrações de saponina esteroidal em diferentes fases do desenvolvimento de Brachiaria decumbens e B. brizantha

Brachiaria species contain steroidal saponins and are involved in outbreaks of hepatogenous photosensitization. This research presents the levels of a steroidal saponin, protodioscin, in the seeds and aerial parts of B. brizantha and B. decumbens during different developmental stages (growth, bloom, fructification and seed fall). The butanolic fraction of the ethanolic extract of each stage was submitted to thin layer chromatography (TLC) and spectrophotometric analysis through the Ehrlich reagent in 515nm. The chromatograms in TLC of the butanolic fraction of B. brizantha and B. decumbens showed similar spots as the protodioscin standard. The estimated level of protodioscin isomers in B. brizantha and B. decumbens ranged from 0.5 percent to 2.1 percent, having the highest level at the end of their developmental stages during seed falling comparison with the previous one. Protodioscin was not detected in the seeds. Outbreaks of Brachiaria spp. poisoning in central Western Brazil are frequently observed in pastures that had been more than 30 days without animals grazing, and also during the growing or blooming stage of the pastures. Other saponin determinations in toxic and non toxic pastures are necessary to determine the saponin concentrations that cause intoxication.

As Brachiaria spp contêm saponinas esteroidais envolvidas no desenvolvimento de fotossensibilizacão hepatógena. No presente trabalho foram determinados os teores da saponina esteroidal protodioscina nas partes aéreas de B. brizantha e B. decumbens, durante as diferentes fases do desenvolvimento (crescimento, floração, frutificação e queda das sementes) e nas sementes. A fração butanólica do extrato etanólico de cada fase foi submetida à cromatografia de camada delgada (CCD) e à análise espectrofotométrica por meio do reagente de Ehrlich em 515nm. Os cromatogramas em CCD da fração butanólica de B. brizantha e B. decumbens, de cada fase do desenvolvimento, apresentaram manchas similares ao padrão de protodioscina. Por meio da análise de protodioscina por espectrofotometria, os teores de protodioscina em B. brizantha e B. decumbens variaram entre 0.5 por cento e 2.1 por cento, sendo mais altos na fase de queda das sementes. Nas sementes não foi encontrada protodioscina. Surtos de intoxicação por Brachiaria spp. no Centro-Oeste brasileiro são freqüentemente observados em pastagens diferidas por mais de 30 dias e também durante as fases de crescimento e florescimento. São necessárias outras dosagens de saponinas em pastagens tóxicas e não-tóxicas para determinar as concentrações capazes de causar intoxicação.

Intoxicaçäo por Vernonia rubricaulis em bovinos no Mato Grosso do Sul / Intoxication by Vernonia rubricaulis in cattle in Mato Grosso do Sul

Descrevem-se surtos de intoxicaçäo por Vernonia rubricaulis em bovinos em nove fazendas no Estado de Mato Grosso do Sul, entre setembro de 1999 e maio de 2001. No total morreram pelo menos 954 animais. Alguns fatores foram aparentemente importantes para a ocorrência da intoxicaçäo: a utilizaçäo de técnicas que favorecem a brotaçäo da planta incluindo a utilizaçäo da roçadeira ("trilho") para o controle de plantas invasoras, assim como a queima ou o desmatamento do campo; o transporte de animais procedentes de outras fazendas ou de outros piquetes da mesma fazenda, com ou sem manejo de animais no curral; e a superlotaçäo de piquetes. O curso clínico variou de 12 a 48 horas. Os sinais clínicos foram, principalmente, agressividade ou depressäo, salivaçäo, cegueira, gemidos, incoordenaçäo, retraçäo de abdômen, fezes ressecadas com muco e estrias de sangue, focinho seco e decúbito. A letalidade foi de 100 por cento. Os principais achados de necropsia foram observados no fígado. As lesöes hepáticas variavam num mesmo animal e entre diferentes animais. Areas focais vermelhas de hemorragias com tamanhos variando entre 1mm e 25cm, foram observadas em meio ao tecido hepático amarelado em alguns casos. Fígados inteiros ou áreas hepáticas com aspecto de noz-moscada e fígados difusamente amarelados com ou sem hemorragias petequiais, também foram observados. Ocorriam, também, hemorragias em diferentes tecidos e órgäos. As principais alteraçöes histológicas caracterizaram-se por necrose centrolobular com vacuolizaçäo dos hepatócitos das áreas periportais e intermediárias ou necrose massiva e vacuolizaçäo difusa dos hepatócitos. A intoxicaçäo foi reproduzida experimentalmente em três bovinos. A menor dose que causou morte foi de 3g/kg da planta verde fresca em fase de brotaçäo. Os sinais clínicos e as lesöes macro e microscópicas observadas foram semelhantes às apresentadas pelos animais intoxicados naturalmente
