Abstract: The objective of present study was to evaluate the transmissibility of the caprine arthritis-encephalitis virus (CAEV) through artificial insemination (AI), and to assess the influence of viral load on this probable transmission. It also aims to verify whether the inflammatory process caused by the use of intravaginal sponges would facilitate virus entry in the female reproductive tract. For this purpose, 30 undefined breed goats were used, all serologically negative for CAEV. One Anglo-Nubian buck, also seronegative, was used to artificially inseminate females in this study. His semen was contaminated with the standard CAEV-Cork virus strain, with two distinct infective titres, one 106 TCID50/mL, for high viral load (HVL), and another of 102 TCID50/mL, for low viral load (LVL). Females had estrus synchronised by using two protocols, intravaginal sponges in Group 1 (G1, N = 15) and auricular subcutaneous implants in Group 2 (G2, N = 15). For inseminations, the goats were divided into three groups of 10 animals each. One group was inseminated with HVL, another with LVL and the third with semen from the same virus-free buck, as a negative control. The experiment was conducted in accordance to the ethical principles for animal experimentation. Statistical analyses were performed by the chi-square test (P < 0.05). Thirty days after insemination, the experimental infection was confirmed, when 12 out of the 20 (60%) inseminated goats had seroconverted. Sixty days after insemination, all females from the HVL and LVL groups presented anti-CAEV antibodies. There was no statistical difference (P > 0.05) among groups regarding viral loads nor between the two estrus synchronisation protocols. Goats from the control group remained seronegative throughout the experiment (12 months). Concerning reproductive parameters, no difference was found between the control group and the infected groups. Based on these results, it is possible to conclude that the virus can be transmitted through artificial insemination with infected semen. Therefore, the venereal route is a potential route of infection.

The objective of this study was to identify sorghum varieties that have growth and grain yield potential under saline conditions. The study was conducted in 2016 at a greenhouse of the Embrapa Semiárido, in Petrolina, state of Pernambuco, Brazil (9° 8? 8.9?? S, 40° 18? 33.6?? W, and altitude of 373 m). A randomized block experimental design, with a 6 × 5 factorial arrangement, and three replications was used. The treatments consisted of six grain sorghum varieties (1011-IPA, 2502-IPA, 2564-IPA, 2600-IPA, Ponta Negra, and Qualimax), and five salinity levels of the irrigation water (ECw = 0, 1.5, 3.0, 6.0, and 12.0 dS m-1). Plant height, stem diameter, dry matter yield, width and length of the +3 leaf, total leaf area, water use efficiency, and grain yield were evaluated. The sorghum varieties 2502-IPA and 1011-IPA presented the highest grain yields when using an ECw of 6.0 dS m-1, followed by Ponta Negra, Qualimax, and 2600-IPA. The 2564-IPA, 2600-IPA, and Qualimax varieties were more sensitive to the salinity effects, with reductions of 50% of the production with ECw of 3.52, 2.75, and 4.38 dS m-1, respectively. |
