Abstract. The objective was to compare the behavioural and productive response of cows to either abrupt or two-step weaning with nose flaps. Calves were fitted with nose flaps during the 14 days before separation from their dams (NF group); were abruptly and permanently separated (AW group), or remained as non-weaned controls (NW group). The behaviour of the cows was recorded before and after nose-flap insertion and permanent separation. Milk yield and composition were determined. After permanent separation, milk yield of NW cows was greater than that of NF and AW cows. AW cows paced and vocalised more than NF and NW cows, and NF cows more times than NW cows. The two-step weaning method with nose flaps was positive for the wellbeing of cows, as it reduced the main behavioural changes that indicate distress and decreased the bodyweight loss. Weaning, either in one or two steps, decreased milk yield 1 week after permanent separation. |

ABSTRACT.
Some entomopathogenic fungi such as Metarhizium and Beauveria not only have the ability to infect and kill insects but also the capability to associate with plant roots. The potential benefits from this plant-fungus association include nutrient acquisition, plant growth promotion and protection against stressors. The objective of this study was to evaluate the delivery of entomopathogenic fungi in seed coating to determine whether the fungal presence affected maize performance. Additionally, fungal biocontrol ability was assessed in terms of plant resistance to the larvae of Costelytra giveni (Coleoptera: Scarabaeidae) and to the fungus Fusarium graminearum (Nectriaceae). Maize seeds were coated with conidia from Metarhizium spp. or Beauveria bassiana and plant performance was evaluated as seed germination and plant dry weight. Larval mortality and the presence of Fusarium root rot symptoms were also determined. The entomopathogenic fungal persistence on the maize rhizosphere was demonstrated with a M. anisopliae isolate expressing the green fluorescent protein. Presence of both challengers was detrimental to maize performance with 33% reduction in root dry weight in control plants while no variation was observed when the entomopathogenic fungi were used to coat seeds. Some seed coatings resulted in up to 67% mycosis of C. giveni larvae and a reduction in Fusarium rot root symptoms between 24?44%. This study showed that seed coating with conidia of Metarhizium or Beauveria can be used as a delivery system for pests and plant pathogen control, while at the same time hyphae formed a close association with plant roots after conidial germination.
