| Urospermia in horses | Author : Jailson Honorato, José Adalmir Torres de Souza, Deyse Naira Mascarenhas Costa, Diego Carvalho Viana | Abstract | Full Text | Abstract :Contamination of the raw semen with urine can result in irreversible damage to the semen. The sensitivity of spermatozoa to osmotic damage differs markedly between species. Urospermia has been associated with intermittent subfertility and infertility in the horse. The cause may involve failure of the bladder sphincter occlusion and a functional disorder in the components of the autonomic sympathetic and parasympathetic autonomic nervous system that control urination, erection, and ejaculation. Few studies have been done reporting the effects of urospermia on changes in pH, osmolality and motility of equine semen, but it has been reported in the literature that a urospermic condition leading to
a hyperosmolar solution is detrimental to sperm motility in horses |
| O vírus ORF (Ectima Contagioso) | Author : Rosana Léo de Santana | Abstract | Full Text | Abstract :Contagious ecthyma is a severe and proliferative viral disease affecting ovine and caprine species, and eventually men, caused by the contagious ecthyma virus (ECV) of the Parapoxvirus genus. The disease is spread worldwide, including in Brazil, where in the state of Pernambuco, due to its endemicity, can be mistaken by other vesicular diseases such as the Foot and mouth Disease, which requires its diagnostic differentiation. Meanwhile, the control of the infection in endemic regions is limited due to the difficulties in replicating the virus in cell cultures, for the development of
vaccines |

| Plant extracts in the biological control of Botrytis cinerea organic strawberry | Author : Cristiano Pereira da Silva, Rafaella Caroline Bernardi Marchiotti | Abstract | Full Text | Abstract :Strawberry culture is one of the most difficult when it comes to the biological control of fungi. The use of plant extracts
as an alternative control to minimize the incidence of persistent fungi in crops or planting areas has been researched in
recent years, in the search for more natural control and less harmful to the environment and human health. The objective
of this work was to verify the effect of the extracts of the plants, losna (Artemisia absinthium L.), arruda (Ruta
graveolens L.), pimento-longa (Piper aduncum L.) on the biological control of the fungus Botrytis cinerea. The extracts
were prepared by extracting the crude extract of the plants, diluted in ethanol-based solvents, dosed at 0 (control or
control), 25g.L-1, 50g.L-1, 100g.L-1, 12 treatments, 5 replicates and 10 plants. Among the results obtained, we highlight the concentrations of 100g.L-1 for the extracts of Piper aduncum L. with significant effect on the control of Botrytis cinerea fungi with significant decrease of the presence and infestation in plants as in fruits |
| Grafting in tomato cultivar Yoshimatsu | Author : Luziane Vitor de Souza, Daniel Felipe de Oliveira Gentil | Abstract | Full Text | Abstract :This work verified the compatibility between commercial tomato cultivars and Yoshimatsu by means of grafting.
Approach grafting underwent five treatments (‘Santa Cruz’, ‘Santa Cruz Kada Gigante’, ‘Santa Cruz Kada Paulista’,
‘Santa Clara 5800’ and ‘Gaúcho Melhorado’ scions) plus four repetitions. Full cleft grafting underwent four treatments
(‘Santa Cruz’, ‘Santa Cruz Kada Gigante’, ‘Santa Cruz Kada Paulista’ and ‘Santa Clara 5800’) plus five repetitions.
Yoshimatsu cultivar stood as under stock. Commercial cultivars showed compatibility, with greater affinity between
under stock and ‘Santa Clara 5800’ and ‘Santa Cruz Kada Paulista’ scions, especially upon full cleft grafting (nearly
90% attachment rate) |
| Productivity of gherkin cultivars in different cropping systems | Author : Herodilson Guimarães da Costa, Ana Francisca T. A. Ferreira e Ferreira, Hiroshi Noda, Jânia Lília da Silva Bentes | Abstract | Full Text | Abstract :the family farmers in a traditional way, with the fruit in contact with the soil, which induces the commercial
depreciation of the fruits and the frequent occurrence of diseases. Several techniques have been implemented for the
cultivation of fruit vegetables, being the tutoring one of the most used, for promoting the increase of productivity and to
improve the quality of the fruits. The objective of this work was to evaluate the productivity of three cultivars of
gherkin (North, Northeastern and INPA) in three (undergrowth, in vertical stake and espalier) in the dry and rainy
season in Amazonas. Parameters related to weight, length, diameter and number of fruits were evaluated, and
productivity was estimated. However, the best quality of the fruits was obtained in the cultivation with espalier. Among
the cultivars, INPA presented the best performance. The period of drought was the one that favored the production and
quality of the fruits of maxixe, which is recommended for the planting of this crop in the state of Amazonas |
| Potato genotypes for organic cultivation in Central-West Brazil | Author : Giovani Olegário da Silva, Juliana Zucolotto, Gabriel Emiliano Pereira, Carlos Francisco Ragassi, Agnaldo Donizete Ferreira de Carvalho, Arione da Silva Pereira | Abstract | Full Text | Abstract :Potato genotypes were evaluated under organic cultivation in Central-West Brazil. Seven potato genotypes were
evaluated during three crop seasons, 2016, 2017 and 2018 in a randomized complete block design with five replications.
Productivity (total and marketable and number of marketable tubers) and quality traits (average mass of marketable
tubers and specific gravity) were assessed. IPR Cris and BRSIPR Bel stood out for total productivity along the three
crop seasons. BRSIPR Bel followed by BRS Ana had the highest specific gravity, whereas IPR Cris and BRS F63 had
intermediate values. IPR Cris and BRSIPR Bel can be recommended for cultivation under such conditions |
| Laser sensor for determining the leaf volume of woody plants canopy | Author : André Luís da Silva Quirino, Mauri Martins Teixeira, Haroldo Carlos Fernandes, Francisco de Assis de Carvalho Pinto, Alexandre Santos Brandão | Abstract | Full Text | Abstract :This study aims to evaluate the performance of the laser sensor, Model LMS 111, in the extraction of features related to
the canopy of woody plants. To validate the proposal, an adult coffee plant was placed in controlled conditions. For leaf
volume reconstruction technique the LMS 111 was mounted on a mobile platform controlled at 1, 3 and 6 km/h. In such
case, the time required to determine the volume of a plant from the cloud point was lower than the time required to
leave the end of one plant and to start capturing information from the next one |
| Intake and digestibility of diets containing extruded castor meal provided to lactating goats | Author : Sueli Freitas dos Santos, Magno José Duarte Cândido, Marco Aurélio Delmondes Bomfim, Diego Barcelos Galvani, José Luis Ramirez Ascheri | Abstract | Full Text | Abstract :The objective was to evaluate the intake, apparent digestibility and nitrogen balance in dairy goats fed diets containing
extruded food-based castor meal (EFCM) in dairy goats. The non-fibrous carbohydrate intake (g / d) was affected (P
<0.05), presenting a positive linear relashionship with inclusion level of EFCM. The was no influence of treatment on
the DMD, OMD, CPD, NDFD DEE and nutrients, causing linear effect (P <0.05). As well as in DCNF that showed a
quadratic effect (P <0.05). It was observed that the values found for fecal nitrogen, were affected (P <0.05). The results
indicate that the EFCM despite causing a reduction in digestibility of nutrients, can be used in replacement of soybean
meal in diets of dairy goats without reductions in nutrient intake, and without providing any damage to animal health |
