| The objective of this work was to evaluate the influence of low-stress handling (LSH) on reactivity score and pregnancy rate during fixed-time artificial insemination (FTAI) for extensively raised Nellore cows. Multiparous cows (n = 126) were randomly allocated into two groups: G1 (n = 66) and G2, the control group (n = 60). Group G1 was subjected to LSH, in which the animals were handled in a calm and quiet manner, without loud noises or physical aggression, using the point of balance, respecting the flight zone and using flags to supplement handling. Group G2 was handled following the typical procedure, with yelling, kicking and the use of electric prods and sticks. On D0, D8 and D10, FTAI was performed in both groups. Reactivity was scored on D0, D8 and... |

| ABSTRACT Cucumber mosaic virus (CMV) is one of the most economically damaging viral pathogens affecting vegetable crops around the world. In the present research, 50 cabbage (Brassica oleracea L.) lines chosen from the Black Sea Agricultural Research Institute (BSARI, Turkey) were evaluated for their reaction to CMV. The level of resistance to CMV was determined based on biological assays, symptom expression, disease severity rating, and viral titer, as determined by ELISA. Eight cabbage lines were identified as moderately susceptible and 3 were susceptible to the CMV-BA isolate. These plants exhibited various symptoms and accumulated high levels of virus titer. However, the results showed that 17 lines had high resistance, 12 were found to be resistant... |
