1. Storage of boar semen at 16-18 °C in the long-term commercial extender prepared with deionized water or nanowater
Abstract The aim of this study was to assess the usefulness of nanowater (NW; water declusterized using cold plasma treatment) as a diluent for a commercial boar semen extender during the 15-day storage (Days 1 to 15) at 16-18 °C. Ejaculates collected from 8 boars were subjected to the standard evaluation and then diluted in the extender prepared with deion

2. Invasive wild boars and native mammals in agroecosystems in the Atlantic Forest of Western Brazil
Resumo: O objetivo deste trabalho foi estimar um índice de biomassa relativa por espécie, em uma comunidade de mamíferos de médio a grande porte, assim como determinar como o javali (Sus scrofa) invasor se ajusta a esse índice, e verificar se a ocupação de locais por cães interfere na ocupação por javalis e quanto o período de atividade dos cães

3. Addition of chlorogenic acid and caffeine during the processing of cooled boar semen
RESUMO O objetivo deste estudo foi avaliar os efeitos da adição de ácido clorogênico (ChA) antes do resfriamento e sua combinação com cafeína adicionada durante o reaquecimento sobre a qualidade do sêmen suíno resfriado. Dez ejaculados foram diluídos em diluidor comercial com adição ou não de 4,5mg/mL de ChA e armazenados a 15°C. Após zero, 24

4. Risk of exposure of farms and subsistence nurseries to contact with wild boar in southern Mato Grosso do Sul
RESUMO: Com o avanço da distribuição do javali no ambiente rural, seus impactos não se restringem somente a sanidade suidea, embora as exigências quanto ao monitoramento e controle da espécie sejam exigências previstas pela OIE, para o reconhecimento do status de zona livre de peste suína clássica. A construção de modelos ecológicos de favorabili

5. Organic selenium supplementation is cost-effective for increasing the number of seminal doses produced by sexually mature boars
ABSTRACT The present experiment was carried out to evaluate the economic viability of supplementing boar diets with organic selenium aiming to increase the number of seminal doses of sexually mature boars. Twelve boars were divided into three groups: control group received 0.3 mg kg−1 Se from sodium selenite (n = 4), inorganic group received 0.5 mg kg−1

6. Semen quality and reproductive performance of boars kept in pens containing conventional coffee husk as a floor covering
ABSTRACT The objective of this study was to evaluate the putative effects of the use of coffee husk as floor covering on boar semen quality. Sixteen boars were divided into two groups. The first group was held in a conventional system with a compact floor. The second group was kept on a compact floor covered with coffee pods. The experimental period was 60 d

7. Effect of photoperiod on sexual activity of boar
The main objective of this study was to assess the effect of photoperiod on sexual activity of three breeds of boars: Swedish Landrace (n=34), Large White (n=38), and Duroc (n=32). Boar sexual activity was analysed based on the libido index and intensity of ejaculation. The libido index was calculated as the ratio between the duration of ejaculation and time

8. Seasonal variation in sperm characteristics of boars in southern Uruguay
The objective of this study was to evaluate the effects of season, natural photoperiod, and room temperature at the housing facility on boar semen characteristics in Uruguay (34º66'S; 56º29'W). For this purpose, 117 ejaculates, obtained from eight adult males collected through 12 consecutive months, were assessed for sperm viability, DNA integrity, abnorma

9. USO DE DILUENTES ALTERNATIVOS A BAIXAS TEMPERATURAS NA MANUTENÇÃO DA QUALIDADE ESPERMÁTICA DO SÊMEN SUÍNO / USE OF ALTERNATIVE SOLVENTS AT LOW TEMPERATURES IN THE MAINTENANCE OF SPERM QUALITY OF SWINE SEMEN
Countless studies have been conducted with the purpose of improving the conservation of boar semen, either with the use of diluents or alternative temperature ranges, or adding antioxidants or amino acid to the diluent. The present study aimed to define an alternative diluent and temperature preservation of boar semen and evaluate the effects of adding trolo

10. Uso de análise multivariada para determinar a associação do desempenho reprodutivo de machos suinos com as caracteristicas seminais / Use of multivariate analyses to determine the association of boar fertility with semen traits
The application of new approaches that measure certain sperm motion characteristics and their association with boar fertility has shown a recent increase. Computer-assisted semen analysis (CASA) offers standardized assessment of multiple sperm motion parameters and it is plausible that the combination of these parameters with morphological sperm defects may

11. Estudo etiológico e patológico de pneumonias em javalis criados de forma confinada no estado do Rio Grande do Sul / Etiological and pathological study of pneumonia in captive wild-boars in the state of Rio Grande do Sul
As doenças respiratórias são muito comuns na produção intensiva de suínos, já em javalis são escassas informações sobre prevalência, etiologia e apresentação clínico-patológica destas enfermidades. No entanto, a presença de patógenos respiratórios comuns entre javalis selvagens e confinados e suínos domésticos já foi relatada. Este traba

12. Genetic characterization and phylogeography of the wild boar Sus scrofa introduced into Uruguay
The European wild boar Sus scrofa was first introduced into Uruguay, in southern South America during the early decades of the last century. Subsequently, and starting from founder populations, its range spread throughout the country and into the neighbouring Brazilian state Rio Grande do Sul. Due to the subsequent negative impact, it was officially declared
