Article Synopsis
  • Anthelmintic treatment in lactating dairy cattle may improve milk production, but optimal use depends on identifying which cows benefit most, potentially reducing drug resistance.
  • An observational study in south-west Victoria found no significant difference in milk production between cows with low and elevated fecal egg counts (FEC) shortly after calving.
  • The variability in FEC and milk yield across farms indicates that individual FEC results might not effectively identify cows that need anthelmintic treatment in these pasture-based dairy systems.

The purpose of this study was to investigate the influence of an identity leadership-framed reflective practice intervention on perceptions of leadership, social identity, and psychological safety in cricket. Building on previous evidence, an eight-week design included three intervention group coaches and their athletes ( = 32) and three control group coaches and their athletes ( = 34). Measurements of perceived coach identity leadership, social identity, and psychological safety were completed by cricket athletes at week 0 and week 8 for both groups.

In Australian pastoral dairy systems, a variety of 'routine' anthelmintic programs are used in lactating cows varying from nil anthelmintic use to bi-annual application. Anthelmintic resistance has been repeatedly diagnosed on dairy farms and studies have indicated variable milk production benefits from anthelmintics internationally. We aimed to identify the predominant gastrointestinal parasites in recently calved dairy cows in south-west Victoria and examined the relationship between individual faecal egg counts (FEC) and other cow and management factors such as body condition score, age, and historical anthelmintic use.

This was a prospective cohort study to determine how events from birth until first calving affect reproductive performance in the first lactation in pasture-based dairy herds in Victoria, Australia. Events during the preweaning (0 to 84 days), weaning to first breeding (85 to 473 days) and first breeding to first calving periods (474 to 804 days) were recorded and their association with reproductive performance during the first lactation was quantified. Reproductive performance outcomes included the number of days from first mating start date to first service (MSD-S1) and the number of days from first mating start date to first conception (MSD-CON).

Objective: Stress is ubiquitous and how individuals view the nature of stress can influence psychological wellbeing. The present study aimed to investigate the mediating role of proactive coping on the relationships between stress mindset and challenge appraisal tendencies and examine how this in turn related to psychological wellbeing. A secondary aim was to investigate if there were any differences in stress mindset between athletes and non-athletes.
